Abstract

Introduced here are pressure-mitigation systems able to mitigate the pressure applied to a human body by the surface of an object (also referred to as a "structure"). A controller device (or simply "controller") can be fluidly and electrically coupled to a pressure-mitigation device that includes a series of selectively inflatable chambers and a wireless power transmission system integrated adjacent to the chambers. When a pressure-mitigation device is placed between a human body and a surface, the controller can continuously, intelligently, and autonomously circulate fluid through the chambers of the pressure-mitigation device and electrical current through the wireless power transmission system. The controller may cause the chambers to be selectively inflated, deflated, or any combination thereof. The wireless power transmission system may generate an electromagnetic field to emit electrical power to one or more ancillary electronic devices to track ambulation, monitor vital signs, or any combination thereof.

PRESSURE-MITIGATION APPARATUS WITH WIRELESS POWER TRANSMISSION SYSTEM FOR ANCILLARY ELECTRONIC DEVICES

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to US Provisional Application No. 63/674,499, titled “Pressure-Mitigation Apparatus with Wireless Power Transmission System for Ancillary Electronic Devices” and filed on July 23, 2024, which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

[0002] Various embodiments concern pressure-mitigation systems, including pressure-mitigation apparatuses with a wireless power transmission system able to mitigate the pressure applied to a human body by the surface of an object and supply power to ancillary electronic devices and controllers for managing the flow of fluid and electrical current into the pressure-mitigation apparatuses.

BACKGROUND

[0003] Pressure injuries — sometimes referred to as “decubitus ulcers,” “pressure ulcers,” “pressure sores,” or “bedsores” — may occur as a result of steady pressure being applied in one location along the surface of the human body for a prolonged period of time. Regions with bony prominences are especially susceptible to pressure injuries. Pressure injuries are most common in individuals who are completely immobilized (e.g., on an operating table, bed, or chair) or have impaired mobility. These individuals may be older, malnourished, or incontinent — all factors that predispose the human body to formation of pressure injuries.

[0004] These individuals are often not ambulatory, so they sit or lie for prolonged periods of time in the same position. Moreover, these individuals may be unable to reposition themselves to alleviate pressure. Consequently, pressure on the skin and underlying soft tissue may eventually result in inadequate blood flow to the area, a condition referred to as “ischemia,” thereby resulting in damage to the skin or underlying soft tissue. Pressure injuries can take the form of a superficial injury to the skin or a deeper ulcer that exposes the underlying tissues and places the individual at risk for infection. The resulting infection may worsen, leading to sepsis or even death in some cases.

[0005] There are technologies on the market that profess to prevent or treat pressure injuries. While these conventional technologies have many deficiencies, a common theme is the inability to precisely control the spatial relationship between a human body and a support surface (or simply “surface”) that applies pressure to the human body. For example, some cushions allegedly lessen the pressure applied to the human body through the inclusion of a malleable material such as foam or gel, while other cushions allegedly lessen the pressure applied to the human body by shifting the body at least partially toward the left and right lateral recumbent positions. Individuals who use these conventional technologies are still prone to developing pressure injuries or suffering from related complications, as these conventional technologies fail to fully address the reasons that pressure injuries initially develop and continue to worsen over time.

[0022] Various features of the technologies described herein will become more apparent to those skilled in the art from a study of the Detailed Description in conjunction with the drawings. Embodiments are illustrated by way of example and not limitation in the drawings. While the drawings depict various embodiments for the purpose of illustration, those skilled in the art will recognize that alternative embodiments may be employed without departing from the principles of the technologies. Accordingly, while specific embodiments are shown in the drawings, the technology is amenable to various modifications.

DETAILED DESCRIPTION

[0023] The term “pressure injury” refers to a localized region of damage to the skin and/or underlying tissue that results from force being applied thereto that results in contact pressure (or simply “pressure”) on the corresponding anatomical region of the human body. Pressure injuries tend to form over bony prominences, such as the skin and soft tissue overlying the sacrum, coccyx, heels, or hips. However, other sites may also be affected. For instance, pressure injuries may form on the elbows, knees, ankles, shoulders, abdomen, back, or cranium. Pressure injuries may develop when pressure is applied to the blood vessels in soft tissue in such a manner that blood flow to the soft tissue is at least partially obstructed (e.g., due to the pressure exceeding the capillary filling pressure), and ischemia occurs at the site when such obstruction occurs for an extended duration. Accordingly, pressure injuries are normally observed on individuals who are mobility impaired, immobilized, or sedentary for prolonged periods of time.

[0024] Once pressure injuries have formed, the healing process is normally slow. When pressure is relieved from the site of a pressure injury, the body will rush blood (with proinflammatory mediators) to that region to perfuse the area with blood. The sudden reperfusion of the damaged (and previously ischemic) region has been shown to cause an inflammatory response, brought on by the proinflammatory mediators, that can actually worsen the pressure injury (and prolong recovery). Moreover, in some cases, the proinflammatory mediators may spread through the bloodstream beyond the site of the pressure injury to cause a systematic inflammatory response (also referred to as a “secondary inflammatory response”). Secondary inflammatory responses caused by proinflammatory mediators have been shown to exacerbate existing conditions and trigger new conditions (and, again, prolong recovery). Recovery can also be prolonged by factors that are frequently associated with individuals who are prone to pressure injuries, such as old age, immobility, preexisting medical conditions (e.g., arteriosclerosis, diabetes, or infection), smoking, and medications (e.g., antiinflammatory drugs). Inhibiting the formation of pressure injuries (and reducing the prevalence of proinflammatory mediators) can enhance and expedite many treatment processes, especially for those individuals whose mobility is impaired during treatment. [0025] Individuals whose mobility is impaired tend to remain sedentary — either on a chair or bed during treatment. In many cases, one or more monitoring electronic devices (or simply “monitoring devices”) are coupled to these individuals, to the chair or bed, or to both. Examples of monitoring devices include those that track ambulation (e.g., when a patient walks or gets up without assistance) and monitor vital signs such as heart rate, respiratory rate, oxygen saturation, and blood pressure. These monitoring devices are examples of ancillary electronic devices (or simply “ancillary devices”) that provide support in terms of initiating, providing, or documenting treatment. Examples of monitoring devices include motion sensors (e.g., active motion sensors, such as vibration sensors, tilt sensors, accelerometers, ultrasonic sensors, active infrared sensors, and the like, and passive motion sensors, such as passive infrared sensors, ambient light sensors, and the like), pulse oximeters, electrocardiographs, blood pressure monitors, blood glucose meters, continuous glucose monitors, drug infusion pumps, ventilators, intermittent pneumatic compression devices (also called “IPC devices”), etc. Documenting electronic devices (or simply “documenting devices”) via which information can be input — for example, for entry in an electronic health record — can also be characterized as ancillary devices. Examples of documenting devices include mobile workstations, laptop computers, and tablet computers. Individuals suffering from long-term immobility may also be coupled to — or treated with — larger ancillary devices, such as IPC devices, pressure relief mattresses (also called “air mattresses”), and the like.

[0026] Generally, each ancillary device requires power be supplied by a separate cable, especially if used for extended durations (e.g., hours or days), as is often the case for individuals whose mobility is impaired. However, when many ancillary devices are used to provide a patient with optimal care, the ancillary devices may create cable management issues. For example, if every electronic device includes a separate cable that electrically couples it to a power source, an excess of cables may surround the patient. This not only tends to make patients uncomfortable but can also materially limit movement around the patient’s space, making it more difficult for healthcare professionals to access the space for treatment of the patient and/or maintenance of the ancillary devices. Examples of healthcare professionals include doctors, nurses, therapists, members of clinical staff, and the like.

[0027] Battery-powered devices, easily replaceable devices, and disposable devices have been implemented to reduce the cable wiring surrounding a patient’s space. However, these remedies create issues in and of themselves, as battery-powered devices often die when used continuously for extended periods of time, requiring healthcare professionals to replace or recharge those devices frequently. This creates a power management issue that requires healthcare professionals to spend extra time monitoring the patient’s devices. These frequent exchanges can be time consuming, especially when performed for multiple devices used for each of multiple patients throughout the course of treatment. Exchanges can include but are not limited to removing cables, removing devices, recharging devices, replacing devices, replacing one or more batteries of a device, etc. While ancillary devices may be effective in monitoring, providing, or documenting treatment, there has been no way to monitor and coordinate the power supply provided to these devices to reduce the number of exchanges required by healthcare professionals.

[0028] Introduced here, therefore, are pressure-mitigation systems (or simply “systems”) that are designed to mitigate the pressure applied to a living body by the surface of an object (also referred to as a “structure”). Note that while embodiments are generally described in the context of human bodies, the systems could also be designed and used for mitigating the pressure applied to other living bodies (e.g., animal bodies). As further discussed below, a pressure-mitigation system can include a controller device (or simply “controller”) and a pressure-mitigation device (also referred to as a “pressure-mitigation apparatus” or a “pressure-mitigation pad”) that includes a series of selectively inflatable chambers (also referred to as “cells” or “compartments”) and a wireless power transmission system (also referred to as “wireless power transfer system”). The controller can be fluidly coupled to the pressure-mitigation device. When the pressure-mitigation device is placed between a living body and a surface, the controller can continuously, intelligently, and autonomously circulate fluid through the chambers of the pressure-mitigation device. Normally, the controller circulates air through the chambers of the pressure-mitigation device, though the controller could circulate another fluid, such as water or gel, through the chambers of the pressuremitigation device. As discussed further below, the controller may cause the chambers to be selectively inflated, deflated, or any combination thereof.

[0029] The controller can also be electrically coupled to the wireless power transmission system included in the pressure-mitigation device. Specifically, the controller can be electrically coupled to a wireless power transmission system via electrical wiring. This electrical wiring could be included in multi-channel tubing that is interconnected between the controller and pressure-mitigation device. Alternatively, this electrical wiring could be included in separate tubing (also called an “electrical conduit”) that is interconnected between a power interface accessible along an exterior surface of the controller and a power interface accessible along an exterior surface of the pressure-mitigation device. When one or more ancillary devices are placed in proximity to the wireless power transmission system, the ancillary devices can receive electrical energy that is emitted by the wireless power transmission system. In some embodiments, the controller constantly supplies electrical current to the wireless power transmission system — or at least as long as the controller is operating— such that the wireless power transmission system constantly emits electrical energy. In other embodiments, the controller supplies electrical energy to the wireless power transmission system in response to a determination that one or more ancillary devices are proximate to the pressure-mitigation device. The wireless power transmission system can thereby supply power to ancillary devices, either constantly or periodically (e.g., on an ad hoc basis). The power source for the controller can be a single external power source (e.g., electrical energy coming from a wall outlet in the form of a constant voltage). For example, the controller may be electrically coupled to a wall outlet via an electrical cable with a plug, and the controller may use some electrical energy obtained from the wall outlet for its own operations and transmit some electrical energy obtained from the wall outlet to the wireless power transmission system. Such an approach allows a single power source — for example, the wall outlet — to power the pressuremitigation system and one or more ancillary devices, significantly reducing the wiring in the patient’s vicinity and the amount of ancillary device management (e.g., from exchanging ancillary devices, replacing batteries, etc.). [0030] The present disclosure concerns various aspects of systems that comprise one or more pressure-mitigation devices with a wireless power transmission system. In some embodiments, the one or more pressure-mitigation devices include one or more inflatable chambers whose pressure can be regulated by a single controller that independently regulates fluid flow into the inflatable chambers of the one or more pressure-mitigation devices. Because each of these devices includes at least one inflatable chamber, these devices are capable of being pressurized and, therefore, may be referred to as “pressurizable devices.” Accordingly, the controller may be fluidly coupled to — and responsible for managing fluid flow into — multiple pressurizable devices. These multiple pressurizable devices are generally deployed to apply pressure to, or alleviate pressure from, different anatomical regions of the same living body, though these multiple pressurizable devices could be deployed to apply pressure to, or alleviate pressure from, different living bodies.

[0031] As the size of the pressure-mitigation device increases — for example, to have a form comparable to a fitted mattress — additional functionalities, such as the wireless power transmission system, can be implemented. The controller may be electrically coupled to — and responsible for managing electrical current flow into — the wireless power transmission system. The controller may be programmed to identify at least one ancillary electronic device within a predetermined proximity to the wireless power transmission system. For example, the at least one ancillary electronic device can emit an electronic signature detectable by the controller. Accordingly, the controller may control and regulate electrical current, by one or more electrical wires, to the wireless power transmission system such that the wireless power transmission system can emit power (e.g., via a generated electromagnetic field) to the at least one ancillary electronic device. Additionally, a user (e.g., a patient, healthcare professional, etc.) may indicate, via controls of the controller, when electrical power from the wireless power transmission system should be emitted to the at least one ancillary electronic device. In some embodiments, a wireless power transmission system can be integrated into the pressure-mitigation device, either below or alongside the inflatable chambers. The wireless power transmission system can supply power to ancillary electronic devices, such as electronic devices that track ambulation or monitor vital signs. Depending on the amount of electrical power available, the wireless power transmission system can further supply power to larger ancillary electronic devices, like IPC devices. It is worth noting that although the wireless transmission system can be integrated into the pressure-mitigation device, the at least one ancillary electronic device that receives electrical power from the wireless transmission system is not necessarily required for the operation of the pressure-mitigation device. Rather, the at least one ancillary electronic device may be used to assist in monitoring treatment of the patient and/or to relieve some responsibilities of healthcare professionals.

[0032] In some embodiments, the single controller regulates fluid flow into multiple pressurizable devices and electrical current flow into the wireless power transmission system in accordance with different schedules and/or timing schedules. These pressurizable devices can be used to manage multiple individuals (also referred to as “patients,” “subjects,” or “users”), or these pressurizable devices can be used to manage a single individual in an attempt to relieve pressure from, or apply pressure to, multiple anatomical regions. These pressurizable devices may be employed in an effort to promote and monitor early mobilization to aid in (and expedite) the recovery of injuries affecting different anatomical regions. In addition, the ancillary electronic devices, powered by the wireless power transmission system, can collect patient data (e.g., mobility or vitals data) that can be used to track a patient’s progress and make health-related insights. As further discussed below, these pressurizable devices can be designed for deployment in a home setting, a hospital setting, or both. For example, systems designed for a home setting may include, offer, or support features that might otherwise be provided by equipment accessible in a hospital setting. Likewise, systems designed for a hospital setting may include, offer, or support features that might otherwise be provided by equipment accessible in a home setting. Note that the term “hospital setting” is intended to cover various healthcare environments, including clinics, therapy facilities, surgery facilities, and the like, and not simply hospitals.

[0033] The embodiments disclosed herein propose a solution to both the cable management issues and the power management issues described above by integrating the wireless power transmission system into the pressure-mitigation system. In some embodiments, the wireless power transmission system is integrated into one or more regions of the pressure-mitigation device itself. For example, the wireless power transmission system can be a coil, pad, mat, disc, transmitter, etc., integrated below or alongside the inflatable chambers of the device. The wireless power transmission system can be integrated into the device such that pressure applied to the device (e.g., by the patient sitting or lying down on the device) does not break the wireless power transmission system. It can also be advantageous to include the wireless power transmission system in a location that is adjacent to the inflatable chambers in an area that does not make direct contact with the skin of the patient since the wireless power transmission system may radiate heat. Radiated heat may cause patient discomfort and/or thermal application to unintended areas.

[0034] Such an approach to mitigating pressure and supplying power to ancillary electronic devices is useful in various contexts.

[0035] Assume, for example, that an individual has been identified as a candidate for treatment after entering a hospital. In such a scenario, a healthcare professional may obtain a portable pressure-mitigation system (or simply “system”) comprised of a pressure-mitigation device with a wireless power transmission system and a controller. The healthcare professional can deploy the pressure-mitigation device on a surface on which the individual is to be immobilized, either partially or entirely, and then orient the individual on top of the pressure-mitigation device. Thereafter, the healthcare professional can cause the system to shift a point of pressure applied by the surface to the individual by pressurizing the inflatable chambers of the pressure-mitigation device to varying degrees in accordance with a programmed pattern. For example, the healthcare professional may initiate pressurization of the inflatable chambers by indicating that treatment should begin via the controller. In addition, the controller may indicate that the individual’s heart rate monitor and ambulation tracker are compatible with wireless charging and are within proximity of the wireless power transmission system. The healthcare professional can indicate via the controller that these devices should be charged using the wireless power transmission system.

[0036] As another example, assume that an individual has been instructed to utilize a pressure-mitigation device as part of a treatment regimen (e.g., following discharge from a hospital). In such a scenario, the individual may be provided with a system comprised of a pressure-mitigation device with a wireless power transmission system, a wireless ambulation tracking device, and a controller. When the individual reaches her home, she can deploy the pressure-mitigation device on a surface on which she is to be immobilized. For example, the individual may arrange the pressure-mitigation device on a chair or bed, as further discussed below. After the individual arranges herself on top of the pressure-mitigation device, she can cause the system to shift a point of pressure applied by the surface to her body by pressurizing the inflatable chambers of the pressure-mitigation device to varying degrees in accordance with a programmed pattern. For example, the individual may interact with the controller in such a manner (e.g., by pressing a mechanical interface component, such as a button or switch) so as to indicate that fluid should begin flowing into the pressure-mitigation device. In addition, the controller may indicate (e.g., via a display or a mechanical interface component) that the individual’s ambulation tracking device may be paired with the wireless power transmission system. The individual may interact with the controller (e.g., by pressing the display or a mechanical interface component) so as to indicate that electrical current should begin flowing into the wireless power transmission system. Those skilled in the art will recognize that a similar process may be performed if the system is provided to, or deployed by, a caregiver of the individual. Note that the term “caregiver,” as used herein, is generally used to refer to a person who helps another person to receive treatment but is not herself a healthcare professional. Examples of caregivers include family members, friends, and aides.

[0037] Embodiments may be described with reference to particular pressurizable devices, anatomical regions, treatment regimens, environments, etc. However, those skilled in the art will recognize that the features are similarly applicable to other pressurizable devices, anatomical regions, treatment regimens, environments, etc. As an example, embodiments may be described in the context of multiple pressuremitigation devices that are positioned adjacent to different anatomical regions of the individual. However, aspects of those embodiments may apply to a controller that manages fluid flow and electrical current flow into a single pressure-mitigation device with a wireless power transmission system and another pressurizable device with a wireless power transmission system or multiple pressurizable devices with one or more wireless power transmission systems. Embodiments may be described in the context of pressure-mitigation devices for the purpose of illustration only, as pressure-mitigation devices and methods of operation are discussed in greater detail with reference to Figures 1 A-B, 5-6B, and 8-1 1 .

[0038] While embodiments may be described in the context of machine-readable instructions, aspects of the technology can be implemented via hardware, firmware, or software. As an example, a controller may not only execute instructions for determining an appropriate rate at which to permit fluid (e.g., air) to flow into each inflatable chamber of a pressure-mitigation device but may also be responsible for facilitating communication with other computing devices. For example, the controller may be responsible for determining if wireless ancillary electronic devices are within range of the wireless power transmission system and whether to provide power to the ancillary electronic devices. In an additional example, the controller may be able to communicate with a mobile device that is associated with the individual or a caregiver, or the controller may be able to communicate with a computer server of a network-accessible server system. In some scenarios, the controller can notify the user that one or more ancillary devices are within range of the wireless power transmission system on the user’s mobile device and the user can select which of the ancillary electronic devices to provide power to.

Terminology

[0039] References in the present disclosure to “an embodiment” or “some embodiments” mean that the feature, function, structure, or characteristic being described is included in at least one embodiment. Occurrences of such phrases do not necessarily refer to the same embodiment, nor are they necessarily referring to alternative embodiments that are mutually exclusive of one another.

[0040] Unless the context clearly requires otherwise, the terms “comprise,” “comprising,” and “comprised of” are to be construed in an inclusive sense rather than an exclusive or exhaustive sense (i.e. , in the sense of “including but not limited to”). The term “based on” is also to be construed in an inclusive sense rather than an exclusive or exhaustive sense. Thus, unless otherwise noted, the term “based on” is intended to mean “based at least in part on.”

[0041] The terms “connected,” “coupled,” and variants thereof are intended to include any connection or coupling between two or more elements, either direct or indirect. The connection or coupling can be physical, logical, or a combination thereof. For example, elements may be electrically or communicatively coupled to one another despite not sharing a physical connection.

[0042] The term “module” may refer broadly to software, firmware, hardware, or combinations thereof. Modules are typically functional components that generate one or more outputs based on one or more inputs. A computer program may include or utilize one or more modules. For example, a computer program may utilize multiple modules that are responsible for completing different tasks, or a computer program may utilize a single module that is responsible for completing all tasks.

[0043] When used in reference to a list of multiple items, the word “or” is intended to cover all of the following interpretations: any of the items in the list, all of the items in the list, and any combination of items in the list.

[0044] The sequences of steps performed in any of the processes described here are exemplary. However, unless contrary to physical possibility, the steps may be performed in various sequences and combinations. For example, steps could be added to, or removed from, the processes described here. Similarly, steps could be replaced or reordered. Thus, descriptions of any processes are intended to be open-ended.

[0045] A pressure-mitigation device may include one or more chambers (also referred to as “cells” or “compartments”) into which fluid or air can flow. Some pressuremitigation devices include a single chamber, while other pressure-mitigation devices include a plurality of chambers. Each chamber may be associated with a discrete flow of air so that the pressure can be varied as necessary. Figures 1 A-B illustrate an example of a pressure-mitigation device — referred to as an “alignment-facilitating device” — that includes a plurality of chambers, wherein the pressure of each of the chambers can be independently varied. The pressure-mitigation device can further include a wireless power transmission system that can emit electrical energy to power one or more ancillary devices placed in proximity to the pressure-mitigation device. Several examples of pressure-mitigation devices with wireless power transmission systems are described below with respect to Figures 1 A-4. Unless otherwise noted, any features described with respect to one embodiment are equally applicable to other embodiments. Some features have been described only with respect to a single embodiment for the purpose of simplifying the present disclosure.

[0046] Figures 1 A-B are top and bottom views, respectively, of an example pressuremitigation device 100 with a wireless power transmission system 150. The pressuremitigation device 100 is able to relieve the pressure on an anatomical region applied by the surface of an elongated object in accordance with embodiments of the present technology. The wireless power transmission system 150 is able to provide power, continuously or intermittently, to ancillary devices in proximity to the pressure-mitigation device 100. While the pressure-mitigation device 100 may be described in the context of elongated objects, such as mattresses, stretchers, operating tables, and procedure tables, the pressure-mitigation device 100 could be deployed on non-elongated objects. In some embodiments, the pressure-mitigation device 100 is secured to a support surface using an attachment apparatus. In other embodiments, the pressure-mitigation device 100 is placed in direct contact with the surface without any attachment apparatus therebetween. For example, the pressure-mitigation device 100 may have a tacky substance deposited along at least a portion of its outer surface that allows it to temporarily adhere to the surface. Examples of tacky substances include latex, urethane, and silicone rubber.

[0047] As shown in Figure 1 A, the pressure-mitigation device 100 can include a central portion 102 (also referred to as a “contact portion”) that is positioned alongside at least one of the side supports 104. Here, a pair of the side supports 104 are arranged on opposing sides of the central portion 102. However, some embodiments of the pressure-mitigation device 100 do not include any side supports. For example, the side support(s) 104 may be omitted when the individual is medically immobilized (e.g., under anesthesia, in a medically induced coma, etc.) and/or physically restrained by an underlying object (e.g., by rails along the side of a bed, armrests along the side of a chair, etc.) or some other structure (e.g., physical restraints, casts, etc.). However, it may be advantageous to include the side supports 104 when the pressure-mitigation device 100 includes the wireless power transmission system 150. For example, the wireless power transmission system 150 can be in the side supports 104 such that components of the wireless power transmission system 150 do not make direct contact with the skin of the patient, preventing radiated heat from the wireless transmission system 150 from contacting unintended areas.

[0048] As shown in Figures 1 A-B and as described above, the wireless power transmission system 150 can be in one of the side supports 104. More specifically, the wireless power transmission system 150 can include a wireless power source 152 that, when supplied with electrical current from one or more electrical conduits 156, can emit electrical energy to the ancillary devices in proximity to the pressure-mitigation device 100. The electrical conduits 156 can be electrically coupled to an electrical current supply via one or more power interface(s) 154. For example, the power interfaces 154 can electrically couple a controller that can supply electrical current to the electrical conduits 156 that are electrically coupled to the wireless power source 152, enabling the wireless power source 152 to emit electrical energy to power the ancillary devices. The electrical conduits 156 can be electrical wire(s) made of conductive material (e.g., copper, aluminum, metal alloys, etc.) and lined with an insulative material (e.g., silicon rubber, polyurethane, etc.) to prevent damage to the electrical wires and to decrease the amount of heat radiated from the electrical conduits 156.

[0049] The pressure-mitigation device 100 also includes a series of chambers 106 whose pressure can be individually varied. In some embodiments, the series of chambers 106 are arranged in a geometric pattern designed to relieve pressure on specific anatomical region(s) of a human body. As noted above, when placed between the human body and a surface, the pressure-mitigation device 100 can vary the pressure on these specific anatomical region(s) by controllably inflating and/or deflating chamber(s). The electrical conduits 156 can be located generally adjacent to the series of chambers 106 such that the electrical conduits 156 have little to no effect on the inflation and/or deflation of the series of chambers 106. For example, and as shown in Figures 1 A-B, the electrical conduits 156 can be positioned between the series of chambers 106 and one of the side supports 104 on one side of the pressure-mitigation device 100.

[0050] In some embodiments, the series of chambers 106 are arranged such that pressure on a given anatomical region is mitigated when the given anatomical region is oriented over a target region 108 of the geometric pattern. As shown in Figures 1 A-B, the target region 108 may be representative of a central point of the pressure-mitigation device 100 to appropriately position the anatomy of the human body with respect to the pressure-mitigation device 100. For example, the target region 108 may correspond to an epicenter of the geometric pattern. However, the target region 108 may not necessarily be the central point of the pressure-mitigation device 100, particularly if the series of chambers 106 are positioned in a nonsymmetric arrangement. The target region 108 may be visibly marked so that an individual can readily align the target region 108 with a corresponding anatomical region of the human body to be positioned thereon. Thus, the pressure-mitigation device 100 may include a visual element representative of the target region 108 to facilitate alignment with the corresponding anatomical region of the human body. The individual could be a physician, nurse, caregiver, or the patient.

[0051] The pressure-mitigation device 100 can include a first portion 110 (also referred to as a “first layer” or “bottom layer”) designed to face a surface and a second portion 112 (also referred to as a “second layer” or “top layer”) designed to face the human body supported by the surface. In some embodiments, the pressure-mitigation device 100 is deployed such that the first portion 110 is directly adjacent to the surface. For example, the first portion 110 may have a tacky substance deposited along at least a portion of its exterior surface that facilitates temporary adhesion to the support surface. In other embodiments, the pressure-mitigation device 100 is deployed such that the first portion 1 10 is directly adjacent to an attachment apparatus designed to help secure the pressure-mitigation device 100 to the support surface. [0052] One or more components of the wireless power transmission system 150 can be located between the first portion 110 and the second portion 112. For example, the wireless power source 152 can be positioned in one of the side supports 104 between the first portion and the second portion 112. In some embodiments, the electrical conduits 156 are positioned along a periphery of the pressure-mitigation device 100 between the first portion 1 10 and the second portion 1 12. Additionally or alternatively, the electrical conduits 156 can be integrated into the attachment apparatus described above such that a majority of the electrical conduits 156 are not within the pressuremitigation device 100. Said another way, a portion of the electrical conduits 156 are between the first portion 1 10 and the second portion 1 12 to couple the wireless power source 152, and the remainder of the electrical conduits 156 are on the attachment apparatus.

[0053] In some embodiments, the pressure-mitigation device 100 may include multiple wireless power transmission systems. For example, each of the side supports 104 can include one or more of the wireless power transmission systems 150. Each of the wireless power transmission systems 150 can be arranged in different locations and/or can have different or varied power supply parameters (e.g., types of power supply, transmission mechanisms, power strengths, etc.). For example, the pressuremitigation device 100 can include a first wireless power transmission system in one of the side supports 104 and a second wireless power transmission in the other one of the side supports 104. The first wireless power transmission system can be configured to emit a generally stronger or larger electromagnetic field than the second wireless power transmission system, thereby enabling the first wireless power transmission system to supply power to, for example, generally larger ancillary electronic devices and/or more ancillary electronic devices than the second wireless power transmission system.

[0054] In some embodiments, one or more components of the wireless power transmission system(s) 150 can be positioned between the chambers 106 such that the components of the wireless power transmission system(s) 150 do not affect inflation of the chambers 106. For example, the electrical conduits 156 can be positioned between the chambers 106 or on the periphery of the pressure-mitigation device 100 such that the same electrical conduits can be part of the first and second wireless power transmission systems (i.e., the same electrical conduits can supply electrical current to both a first wireless power source and to a second wireless power source of the first and second wireless power transmission systems, respectively). It is worth noting that multiple wireless power transmission systems can be located in various portions of the pressure-mitigation device 100, including but not limited to, within a top, bottom, or side portion of the central portion 102, within a separate overhang portion that extends from the central portion 102 (as described in Figure 3), and/or the like.

[0055] The pressure-mitigation device 100 may be constructed of various materials, and the material(s) used in the construction of each component of the pressuremitigation device 100 may be chosen based on the nature of the body contact, if any, to be experienced by the component. For example, because the second portion 1 12 will often be in direct contact with the skin, it may be comprised of a soft fabric or a breathable fabric (e.g., comprising moisture-wicking materials or quick-drying materials or having perforations). In some embodiments, an impervious lining (e.g., comprised of polyurethane) is secured to the inside of the second portion 112 to inhibit fluid (e.g., sweat) from entering the series of chambers 106 and/or from contacting one or more components of the wireless power transmission system 150. As another example, if the pressure-mitigation device 100 is designed for deployment beneath a cover (e.g., a bed sheet), then the second portion 112 may be comprised of a flexible, liquid-impervious material, such as polyurethane, polypropylene, silicone, or rubber. The first portion 1 10 may also be comprised of a flexible, liquid-impervious material.

[0056] Generally, the first and second portions 110, 112 are selected and/or designed such that the pressure-mitigation device 100 is readily cleanable. However, the specific materials that are used may vary depending on the environment in which the pressure-mitigation device 100 is to be deployed. Assume, for example, that the pressure-mitigation device 100 is intended to be deployed in a hospital environment. In such a scenario, the first and second portions 1 10, 112 may be readily cleanable with a cleaning agent (e.g., bleach) or a cleaning procedure (e.g., sterilization). Because the pressure-mitigation device 100 will remain in the hospital environment under the care of knowledgeable persons, the first and second portions 110, 112 could be comprised of materials that may degrade quickly if not properly cared for. Examples of such materials include high-performance fabric, upholstery, vinyl, and other suitable textiles. If the pressure-mitigation device 100 is instead intended to be deployed in a home environment, the first and second portions 1 10, 1 12 may be comprised of materials that can be readily cleaned by persons without extensive experience. For example, the first portion 110 and/or the second portion 1 12 may be comprised of a vinyl that is easy to clean with commonly available cleaning agents (e.g., bleach, liquid dish soap, all- purpose cleaners). Regardless of the environment, the first and second portions 1 10, 1 12 may contain antimicrobial additives, antifungal additives, flame-retardant additives, and the like. Additionally or alternatively, the wireless power transmission system 150 can be positioned between the first and second portions 1 10, 112 such that materials within the pressure-mitigation device 100 and/or the materials used to clean the pressure-mitigation device 100 do not disturb the electrical performance of the wireless power transmission system 150.

[0057] The series of chambers 106 may be formed via interconnections between the first and second portions 1 10, 112. For example, the first and second portions 110, 112 may be bound directly to one another, or the first and second portions 110, 112 may be bound to one another via one or more intermediary layers. In some embodiments, the electrical conduits 156 can be positioned between the first and second portions 110, 1 12 at the interconnections forming the series of chambers 106. In the embodiment illustrated in Figures 1A-2B, the pressure-mitigation device 100 includes an “M-shaped” chamber intertwined with two “C-shaped” chambers that face one another. Such an arrangement has been shown to effectively mitigate the pressure applied to the sacral region of a human body in the supine position by a support surface when the pressure in these chambers is alternated. The series of chambers 106 may be arranged differently if the pressure-mitigation device 100 is designed for an anatomical region other than the sacral region or if the pressure-mitigation device 100 is to be used to support a human body in a non-supine position (e.g., a prone position or sitting position). Generally, the geometric pattern of chambers 106 is designed based on the internal anatomy (e.g., the muscles, bones, and vasculature) of the anatomical region on which pressure is to be relieved.

[0058] The person using the pressure-mitigation device 100 and/or the caregiver (e.g., a nurse, physician, family member, etc.) may be responsible for actively orienting the anatomical region of the human body lengthwise over the target region 108 of the geometric pattern. If the pressure-mitigation device 100 includes at least one of the side supports 104, the side support(s) 104 may actively orient or guide the anatomical region of the human body laterally over the target region 108 of the geometric pattern. In some embodiments, the side support(s) 104 are inflatable, while in other embodiments, the side support(s) 104 are permanent structures that protrude from one or both lateral sides of the pressure-mitigation device 100. For example, it may be advantageous for the wireless power transmission system 150 to be within a permanent structure to ensure that inflation of the pressure-mitigation device 100 does not impact the electrical components of the wireless power transmission system 150. Additionally or alternatively, at least a portion of each of the side supports 104 may be stuffed with cotton, latex, polyurethane foam, or any combination thereof.

[0059] As further described below with respect to Figures 6A-7C, a controller can separately or independently control the pressure in each chamber (as well as the side supports 104, if included) by providing a discrete airflow via one or more of the valves 1 14. In some embodiments, the valves 1 14 are permanently secured to the pressuremitigation device 100 and designed to interface with tubing that can be readily detached (e.g., for easier transport, storage, etc.). Here, the pressure-mitigation device 100 includes five of the valves 1 14. Three valves are fluidically coupled to the series of chambers 106, and two valves are fluidically coupled to the side supports 104. Other embodiments of the pressure-mitigation device 100 may include more than five valves or fewer than five valves. For example, the pressure-mitigation device 100 may be designed such that a pair of the side supports 104 are pressurized via a single airflow received via a single valve.

[0060] In some embodiments, the controller supplies electrical current to the wireless power transmission system 150 via the power interfaces 154 accessible along the exterior of the pressure-mitigation device 100. Here, the pressure-mitigation device includes two of the power interfaces 154 on either side of one of the valves 114. One of the power interfaces 154 can be an input power interface electrically coupled to one of the electrical conduits 156, and the other one of the power interface 154 can be an output power interface electrically coupled to another one of the electrical conduits 156. In some embodiments, the electrical conduit 156 that electrically couples the input power interface is an “input electrical conduit,” and the electrical conduit 156 that electrically couples the output power interface is an “output electrical conduit.” The input electrical conduit can carry electrical current from the input power interface to the wireless power source 152. The electrical current can travel through the wireless power source 152 to generate an electromagnetic field used to power the ancillary devices in proximity to the pressure-mitigation device 100. The output electrical conduit can carry electrical current from the wireless power source 152 to the output power interface. For example, when the electromagnetic field is no longer needed (e.g., there are no longer ancillary devices in proximity to the wireless power source 152), electrical current flow through the wireless power source 152 can be ceased by directing any stored energy from the wireless power source 152 to the output electrical conduit as electrical current. The output electrical conduit can carry the electrical current to the output power interface, which can direct the electrical current to a discharge path where it dissipates (e.g., through a resistor or similar load). The wireless power source 152 can include one or more coils, inductors, antennas, and/or the like used to transmit electrical energy via an electromagnetic field. The process for inducing an electromagnetic field is described in more detail with reference to Figure 11 .

[0061] In some embodiments, the controller can recognize/detect ancillary electronic devices within a predetermined proximity to the controller and/or the wireless power transmission system 150. For example, the controller can be configured to detect electronic signatures of the ancillary electronic devices within three to five meters of the controller. Depending on the type of wireless power source 152 included in the wireless power transmission system 150 and/or the amount of electrical current available, the predetermined proximity can be generally less or greater than three to five meters. For example, RF frequency antennas are configured to supply electrical energy over a generally greater distance, whereas inductive charging (e.g., Qi) is typically designed to emit electrical energy over only a few millimeters. Thus, the predetermined proximity can be generally larger for RF frequency antennas, and the predetermined proximity can be generally smaller for inductive charging. Additionally, the amount of electrical current flowing through the wireless power source 152 is generally proportional to the size of the electromagnetic field generated by the wireless power source 152. Thus, the predetermined proximity can be generally larger if more electrical current is available to flow through the wireless power source 152, and the predetermined proximity can be generally smaller if less electrical current is available to flow through the wireless power source 152.

[0062] Once the controller identifies one or more ancillary electronic devices within the predetermined proximity, the controller can supply electrical current from an external power source (e.g., a wall outlet) to the wireless power source 152 via the power interface(s) 154 and the electrical conduit(s) 156. As described above and herein, the electrical current flowing through the wireless power source 152 can generate an electromagnetic field that the ancillary electronic devices can receive electrical energy from. In some embodiments, the controller includes a user interface and/or controls that allow a user to identify ancillary electronic devices within the predetermined proximity, select when to supply electrical current to the wireless power source 152, select which ancillary electronic devices to supply electrical energy to, and/or the like. Additionally or alternatively, the controller can be configured to determine the amount of electrical current available to transmit (or the amount being transmitted) to the wireless power source 152 and the corresponding electromagnetic field size. Depending on the size of the electromagnetic field, the controller can determine which ancillary electronic devices to supply electrical energy to. For example, if a generally larger amount of electrical current is available, the wireless power transmission system can emit electrical energy to power larger ancillary devices, such as IPGs. In some embodiments, the controller can automatically select and/or enable ancillary electronic devices to extract electrical energy from the electromagnetic field generated based on an electrical current threshold being reached. The electrical current threshold can generally correspond to the electrical current necessary to maintain operation of one or more of the ancillary electronic devices within the predetermined proximity. [0063] In some embodiments, the pressure-mitigation device 100 includes one or more design features 116a-c designed to facilitate securement of the pressuremitigation device 100 to the surface of an object and/or an attachment apparatus. As illustrated in Figure 1 B, for example, the pressure-mitigation device 100 may include three design features 116a-c, each of which can be aligned with a corresponding structural feature that is accessible along the surface of the object or the attachment apparatus. For example, each design feature 116a-c may be designed to at least partially envelop a structural feature that protrudes upward. One example of such a structural feature is a rail that extends along the side of a bed. The design feature(s) 1 16a-c may also facilitate proper alignment of the pressure-mitigation device 100 with the surface of the object or the attachment apparatus. In some embodiments, a portion or an entirety of the electrical conduits 156 can be located along the periphery of the pressure-mitigation device 100 around one or more of the design features 116a-c such that the electrical conduits 156 can electrically couple the wireless power source 152.

[0064] While not shown in Figures 1 A-B, one or more release valves (also referred to as “discharge valves”) 1 18 may be located along the periphery of the pressuremitigation device 100 to allow for quick discharge of the fluid stored therein. Normally, the release valve(s) 1 18 are located along the longitudinal sides to ensure that the release valve(s) 1 18 are not located beneath a human body situated on the pressuremitigation device 100. Release valve(s) 1 18 may allow discharge of fluid from the side supports 104 and/or the series of chambers 106. In some embodiments, fluid is separately or collectively dischargeable from the side supports 104 (e.g., where each side support has at least one release valve). Such a design is desirable in some scenarios because fluid can quickly be discharged from the side supports 104, which allows the human body situated on the pressure-mitigation device 100 to be accessed (e.g., in the case of a medical emergency). In other embodiments, fluid is only collectively dischargeable from the side supports 104. This approach to “dually deflating” the side supports 104 may be taken if release valve(s) 1 18 are connected to only one side support, though both side supports are fluidically coupled to one another. The release valve(s) 118 may be manually or electrically actuated. For example, the release valve(s) 1 18 may be manually actuated by pressing a mechanical button (also referred to as a “strike button”) that, when pressed, allows fluid to flow out of the corresponding chamber or side support. In embodiments where the fluid is air, the air may be permitted to flow into the ambient environment. In embodiments where the fluid is water or gel, the fluid may be directed into a container (e.g., from which the fluid can then be rerouted through the controller as further discussed below). Similarly, the pressure-mitigation device 100 can include an external circuit breaker (not illustrated) configured to interrupt electrical current flow through the wireless power transmission system 150. The circuit breaker can cause electrical current in the wireless power transmission system 150 to cease if electrical conditions exceed a threshold (e.g., temperature of the wireless power source 152 exceeds a temperature threshold), preventing damage to components of the wireless power transmission system 150 and/or the pressure-mitigation device 100 and ensuring patient safety. As another example, the release valve(s) 1 18 and/or the circuit breaker may be electronically actuated by interacting with a switch assembly (e.g., located along the exterior surface of the pressure-mitigation device 100), a controller, or another computing device (e.g., a mobile phone or wearable electronic device) that is communicatively connected to the pressure-mitigation device 100.

[0065] Figures 2A-B are top and bottom views, respectively, of an example pressuremitigation device 200 able to relieve the pressure on an anatomical region applied by the surface of an elongated object in accordance with embodiments of the present technology. Like the pressure-mitigation device 100 of Figures 1 A-B, the pressuremitigation device 200 of Figures 2A-B can include a wireless power transmission system 250 that may include a wireless power source 252 that, when supplied with electrical current from one or more electrical conduits 256, can emit electrical energy to one or more ancillary devices in proximity to the pressure-mitigation device 200. The pressure-mitigation device 200 and the wireless power transmission system 250 can be identical to or generally similar to the pressure-mitigation device 100 and the wireless power transmission system 150 of Figures 1 A-B, respectively, except that the wireless power transmission system 250 is located on a side support 204 opposite one or more power interfaces 254. The wireless power transmission system 250 can include one or more electrical conduits 256 positioned along a periphery of the pressure-mitigation device 200. For example, the electrical conduits can be positioned along a periphery of a central portion 202 (also referred to as a “contact portion”) to the side support 204 opposite the power interfaces 254. Such an arrangement allows the electrical conduits 256 to remain accessible when a living body is centered over a target region 208 that may correspond to an epicenter of the geometric pattern in which the series of inflatable chambers 206 are arranged.

[0066] As shown in Figure 2B, the electrical conduits 256 can also be positioned around design features 216a-c such that the electrical conduits 256 do not interfere with attachment and/or positioning of the pressure-mitigation device 200. As described above and herein, the electrical conduits 256 can be positioned partially and/or entirely within the pressure-mitigation device 200 in a manner that does not interfere with inflation and/or deflation of a series of inflatable chambers 206 formed via interconnections between a first portion 210 (also referred to as a “first layer” or “bottom layer”) and a second portion 212 (also referred to as a “second layer” or “top layer”) of the pressure-mitigation device 200. The first and second portions 210, 212 are described in more detail with reference to the first and second portions 1 10, 1 12 of Figures 1 A-B.

[0067] Figure 3 is a top view of a pressure-mitigation device 300 with a wireless power transmission system 350 configured in accordance with embodiments of the present technology. The pressure-mitigation device 300 is generally used in conjunction with non-elongated objects that support individuals in a seated or partially erect position. For example, the pressure-mitigation device 300 can include a first portion 302 (also referred to as a “first layer” or “bottom layer”) designed to face the seat of a wheelchair, a second portion 304 (also referred to as a “second layer” or “top layer”) designed to face a human body supported by the seat of the wheelchair, a series of chambers 306 formed by interconnections between the first and second portions 302, 304, and multiple of the valves 308 that control the flow of fluid into and/or out of the chambers 306. Other examples of non-elongated objects include chairs (e.g., office chairs, examination chairs, recliners, etc.) and the seats included in vehicles and airplanes. Accordingly, the pressure-mitigation device 300 may be positioned atop surfaces that have side supports integrated into the object itself (e.g., the side arms of a wheelchair or recliner). Note, however, that the pressure-mitigation device 300 could likewise be used in conjunction with elongated objects in a manner generally similar to the pressuremitigation devices 100, 200 of Figures 1A-2B.

[0068] The pressure-mitigation device 300 can include various features similar to the features of the pressure-mitigation devices 100, 200 described above with respect to Figures 1 A-2B. For example, the pressure-mitigation device 300 may include a series of chambers 306 (also referred to as “a plurality of chambers”) formed via interconnections between the first and second portions 302, 304. In this embodiment, the pressuremitigation device 300 includes an “M-shaped” chamber intertwined with a backward “J- shaped” chamber and a backward “C-shaped” chamber. Varying the pressure in such an arrangement of chambers 306 has been shown to effectively mitigate the pressure applied by a surface to the gluteal and sacral regions of a human body in a seated position (e.g., on the seat of a wheelchair). These chambers may be intertwined to collectively form a square-shaped pattern. Pressure-mitigation devices designed for deployment on the surfaces of non-elongated objects may have substantially quadrilateral-shaped patterns of chambers, while pressure-mitigation devices designed for deployment on the surfaces of elongated objects may have substantially squareshaped patterns of chambers.

[0069] As further discussed below, the chambers 306 can be inflated and/or deflated in a predetermined pattern and to predetermined pressure levels. The individual chambers of the chambers 306 may be inflated to higher pressure levels than the chambers 106, 206 of the pressure-mitigation devices 100, 200 described with respect to Figures 1 A-2B because the human body being supported by the pressure-mitigation device 300 is in a seated position, thereby causing more pressure to be applied by the underlying surface than if the human body were in a supine or prone position. Further, unlike the pressure-mitigation devices 100, 200 of Figures 1A-2B, the pressuremitigation device 300 of Figures 3 does not include side supports. As noted above, side supports may be omitted when the object on which the individual is situated (e.g., seated or reclined) already provides components that will laterally center the human body, as is often the case with non-elongated support surfaces. One example of such a component is the armrests along the side of a chair.

[0070] As shown in Figure 3, the pressure-mitigation device can include an overhang portion 310 that includes the wireless power transmission system 350. The overhang portion 310 can be configured to fit or rest in a gap near, beneath, or in the backrest of the chair supporting the individual in a seated or partially erect position. In some embodiments, the wireless power transmission system 350 radiates heat, and thus, it is advantageous to have the wireless power transmission system 350 on a non-patientcontacting surface of the pressure-mitigation device 300 (e.g., the overhang portion 310). The overhang portion 310 can be a part of at least one of the first and second portions 302, 304. In some embodiments, the overhang portion 310 is only a part of one of the first and second portions 302, 304 and does not inflate. Additionally or alternatively, the overhang portion 310 can be a part of the individual chambers 306 and can partially or entirely inflate. In some embodiments, the overhang portion 310 can be one or more of the side supports described herein (e.g., the side supports 104, 204, and 414 of Figures 1 , 2, and 4, respectively) that are not necessarily inflated. Rather, the side supports can be extensions of a central portion (e.g., the central portion 102 of Figure 1 ) such that the wireless power transmission system 350 is positioned away from at least some of the skin-contacting portions of the pressure-mitigation device 300. It is worth noting that although the overhang portion 310 and thus the wireless power transmission system 350 in Figure 3 are located on a top portion of the pressuremitigation device 300, the overhang portion 310 could also extend from a bottom or side portion of the pressure-mitigation device 300. For example, the overhang portion 310 can extend from the bottom of the pressure-mitigation device 300 and can hang or wrap underneath the latitudinal side of a chair (i.e., underneath the seat). Additionally or alternatively, the overhang portion 310 can extend from a side portion of the pressuremitigation device 300 such that the overhang portion 310 hangs over and/or is accessible along the longitudinal sides of the chair and/or seat. These applications may be especially useful for chairs and/or seats that do not necessarily include an accessible back latitudinal opening. [0071] In some embodiments, the pressure-mitigation device 300 is secured to a surface using an attachment apparatus. In other embodiments, the attachment apparatus is omitted such that the pressure-mitigation device 300 directly contacts the underlying surface. In such embodiments, the pressure-mitigation device 300 may have a tacky substance deposited along at least a portion of its outer surface that allows it to temporarily adhere to the surface. Additionally or alternatively, the overhang portion 310 may include a tacky substance deposited on its outer surface to secure the overhang portion 310 to another portion of the object supporting the individual, such as a back surface of the chair or underneath the seat.

[0072] As can be seen in Figure 3, the pressure-mitigation device 300 can include one or more valves 308 and one or more power interfaces 354. The valves 308 and the power interfaces 354 can be identical or generally similar to the valves 1 14, 214 and power interfaces 154, 254, respectively. Here, however, the valves 308 and the power interfaces 354 can be located near the backrest of the wheelchair (e.g., on or extending onto the overhang portion 310). Such a design may allow the tubing connected to the valves 308 and the power interfaces 354 to be routed through a gap near, beneath, or in the backrest. In some embodiments, the valves 308 extend onto the overhang portion 310 — for example, if the overhang portion 310 is a part of the individual chambers 306 and can partially and/or entirely inflate. However, here, the valves 308 extend from a portion of the pressure-mitigation device 300 positioned on the seat surface toward the back portion of the pressure-mitigation device 300. As described above, the overhang portion 310 can also be on the bottom or side portions of the pressure-mitigation device 300. Similarly, the valves 308 and/or the power interfaces 354 can extend from a bottom or side portion of the pressure-mitigation device 300, for example, if the back longitudinal side of the chair is not readily accessible.

[0073] As further described below with respect to Figures 7A-C, a controller can control the pressure in each chamber 306 by providing a discrete airflow via one or more valves 308. Here, the pressure-mitigation device 300 includes three of the valves 308, and each of the three of the valves 308 corresponds to a single chamber of the chambers 306. Other embodiments of the pressure-mitigation device 300 may include fewer than three valves or more than three valves, and each valve can be associated with one or more chambers to control inflation/deflation of those chamber(s). A single valve could be in fluid communication with two or more chambers. Further, a single chamber could be in fluid communication with two or more valves (e.g., one valve for inflation and another valve for deflation). Additionally or alternatively, the controller can control the electrical current received at one or more electrical conduits 356 via the power interfaces 354. The electrical conduits 356 can be electrically coupled to the wireless power source 352 such that electrical current received at the wireless power source 352 generates an electromagnetic field that ancillary electronic devices can receive electrical energy from. As shown in Figure 3, the wireless power transmission system 350 includes two of the electrical conduits 356 each coupled to one of the power interfaces 354. In some embodiments, one of the electrical conduits 356 and one of the power interfaces 354 are an input electrical conduit and an input power interface, respectively, and the other one of the electrical conduits 356 and the other one of the power interfaces 354 are an output electrical conduit and an output power interface, respectively. Input and output electrical conduits and/or power interfaces are described in more detail with reference to Figures 1 A-2B and 1 1 .

[0074] Figure 4 is a top view of a pressure-mitigation device 400 for relieving pressure on an anatomical region applied by an elongated object in accordance with embodiments of the present technology. As mentioned above, examples of elongated objects include mattresses, stretchers, operating tables, and procedure tables. The pressure-mitigation device 400 can include features similar to the features of the pressure-mitigation device 300 of Figure 3, the pressure-mitigation device 200 of Figures 2A-B, and the pressure-mitigation device 100 of Figures 1 A-B. For example, the pressure-mitigation device 400 can include a wireless power transmission system 450 designed to provide electrical energy to ancillary electronic devices in a predetermined proximity. The wireless power transmission system 450 can include a wireless power source 452 electrically coupled to one or more electrical conduits 456 that carry electrical current from one or more power interfaces 454 to the wireless power source 452 and back to the power interfaces 454. Additionally, the pressure-mitigation device 400 can include a first portion 402 (also referred to as a “first layer” or “bottom layer”) designed to face the surface of the elongated object, a second portion 404 (also referred to as a “second layer” or “top layer”) designed to face a human body supported by the elongated object, a series of chambers 406 formed by interconnections between the first and second portions 402, 404, and multiple valves 408 that control the flow of fluid into and/or out of the chambers 406. As can be seen in Figure 4, the pressuremitigation device 400 may be designed such that the valves 408 and the electrical conduits 456 will be accessible along a longitudinal side of the elongated object. Such a design may allow the tubing connected to the valves 408 or electrical conduits 456 connected to the power interfaces 454 to be routed alongside the elongated object (e.g., along or through a handrail of a bedframe). Alternatively, the pressure-mitigation device may be designed such that the valves 408 and/or the power interfaces 454 are located near the top or bottom of the pressure-mitigation device 400 so as to allow the tubing to be routed along a latitudinal side of the elongated object.

[0075] While the pressure-mitigation devices 100, 200 of Figures 1A-2B are designed to occupy the lumbar, gluteal, and femoral regions while the human body positioned thereon is in the supine position, the pressure-mitigation device 400 of Figure 4 can be designed to also occupy cervical, thoracic, and leg regions. Thus, the pressure-mitigation device 400 may be able to alleviate pressure applied by the elongated object anywhere along the posterior side of the human body between the skull and ankle.

[0076] Embodiments of the pressure-mitigation device 400 could also include (i) a cranial portion 410 (also referred to as a “cranial cushion” or “cranial cup”) that is designed to envelop the posterior side of the cranium while the human body is in the supine position and/or (ii) a heel portion 412 (also referred to as a “heel cushion” or “heel cup”) that is designed to envelop the posterior end of the foot while the human body is in the supine position. The cranial portion 410 and heel portion 412 may include a different number of chambers than the geometric arrangements designed to occupy the lumbar and femoral regions. Generally, the cranial portion 410 and heel portion 412 only include one or two chambers, though the cranial portion 410 and heel portion 412 could include more than two chambers. In embodiments where the pressure-mitigation device 400 includes cranial and heel portions, the pressure-mitigation device 400 may be referred to as a “full-body pressure-mitigation device.” In embodiments where the pressure-mitigation device 400 includes cranial and heel portions, the pressuremitigation device 400 may have a longitudinal form that is at least six feet in length. In embodiments where the pressure-mitigation device 400 does not include cranial and heel portions, the pressure-mitigation device 400 may have a longitudinal form that is at least four feet in length.

[0077] As shown in Figure 4, the pressure-mitigation device 400 can include side supports 414 that are able to orient the human body actively or passively with respect to the chambers of the pressure-mitigation device 400. In some embodiments, a single side support extends longitudinally along each opposing side of the pressure-mitigation device 400. In other embodiments, multiple side supports are located along each opposing side of the pressure-mitigation device 400. As an example, along each longitudinal side, the pressure-mitigation device 400 may include a first side support that is intended to be parallel to the thoracic region and a second side support that is intended to be parallel to the leg region. As another example, along each longitudinal side, the pressure-mitigation device 400 may include a first side support that is intended to be parallel to the thoracic and lumbar regions, a second side support that is intended to be parallel to the leg region, and a third side support that is intended to be parallel to the calf region. Accordingly, the pressure-mitigation device 400 may include more than one side support along each side, and each side support may be responsible for orienting a different anatomical region of the human body. As shown in Figure 4, components of the wireless power transmission system 450 can be located on, within, and/or adjacent to one of the side supports 414 described herein. For example, the wireless power source 452 can be located within one of the side supports 414 such that heat radiated from the wireless power source 452 is not making direct contact with the skin of the patient.

[0078] More generally, the pressure-mitigation device 400 includes a first geometric arrangement of a first series of chambers and a second geometric arrangement of a second series of chambers. When controllably inflated, the first series of chambers can relieve the pressure applied to a first anatomical region of a human body by an underlying surface. Similarly, when controllably inflated, the second series of chambers can relieve the pressure applied to a second anatomical region of the human body by the underlying surface. When the pressure-mitigation device 400 has a longitudinal form, as shown in Figure 4, the first geometric arrangement can be longitudinally adjacent to the second geometric arrangement so as to accommodate the first anatomical region that is superior to the second anatomical region. As shown in Figure 4, the second geometric arrangement may be representative of another instance of the first geometric arrangement that is mirrored across a latitudinal axis that is orthogonal to the longitudinal form of the pressure-mitigation device 400. Alternatively, the second geometric arrangement may be identical to the first geometric arrangement. The wireless power transmission system 450 can be located on, within, and/or adjacent to side portions adjacent to the first and/or second series of chambers.

[0079] Moreover, the pressure-mitigation device may include a third geometric arrangement of a third series of chambers. When controllably inflated, the third series of chambers can relieve the pressure applied to a third anatomical region of the human body by the underlying surface. The third anatomical region may be superior to the anatomical region (e.g., when the third geometric arrangement corresponds to the cranial portion 410), or the third anatomical region may be inferior to the second anatomical region (e.g., when the third geometric arrangement corresponds to the heel portion 412).

[0080] As mentioned above, the pressure-mitigation device could include cranial and heel portions in some embodiments. Therefore, the pressure-mitigation device may include a third geometric arrangement of a third series of chambers and a fourth geometric arrangement of a fourth series of chambers. When controllably inflated, the third series of chambers can relieve the pressure applied to a third anatomical region of the human body by the underlying surface. Similarly, when controllably inflated, the fourth series of chambers can relieve the pressure applied to a fourth anatomical region of the human body by the underlying surface. The third anatomical region may be superior to the first anatomical region, while the fourth anatomical region may be inferior to the second anatomical region. The wireless power transmission system 450 can be located on, within, and/or adjacent to side portions adjacent to the third and/or fourth series of chambers.

Overview of Approaches to Mitigating Pressure

[0081] Figure 5 is a partially schematic top view of a pressure-mitigation device 500 illustrating how a pressure gradient can be created by varying pressure distributions to avoid ischemia in a mobility-impaired patient in accordance with embodiments of the present technology. When a human body is supported by a surface 502 for an extended duration, pressure injuries may form in the tissue overlaying bony prominences, such as the skin overlying the sacrum, coccyx, heels, or hips. Generally, these bony prominences represent the locations at which the most pressure is applied by the surface 502 and, therefore, may be referred to as the “main pressure points” along the surface of the human body.

[0082] To prevent the formation of pressure injuries, healthy individuals periodically make minor positional adjustments (also known as “micro-adjustments”) to shift the location of the main pressure point. However, individuals having impaired mobility often cannot make these micro-adjustments by themselves. Mobility impairment may be due to physical injury (e.g., a traumatic injury or a progressive injury), movement limitations (e.g., within a vehicle, on an aircraft, or in restraints), medical procedures (e.g., those requiring anesthesia), and/or other conditions that limit natural movement. For these mobility-impaired individuals, the pressure-mitigation device 500 can be used to shift the location of the main pressure point(s) on their behalf. That is, the pressure-mitigation device 500 can create moving pressure gradients to avoid sustained, localized vascular compression and enhance tissue perfusion.

[0083] The pressure-mitigation device 500 can also include a series of chambers 504 whose pressure can be individually varied. The chambers 504 may be formed by interconnections between the top and bottom layers of the pressure-mitigation device 500. The top layer may be comprised of a first material (e.g., a permeable, non-irritating material) configured for direct contact with a human body, while the bottom layer may be comprised of a second material (e.g., a non-permeable, gripping material) configured for direct contact with the surface 502. Generally, the first material is permeable to gasses (e.g., air) and/or liquids (e.g., water and sweat) to prevent buildup of fluids that may irritate the skin. Meanwhile, the second material may not be permeable to gasses or liquids to prevent soilage of the underlying object. Accordingly, air discharged into the chambers 504 may be able to slowly escape through the first material (e.g., naturally or via perforations) but not the second material, while liquids may be able to penetrate the first material (e.g., naturally or via perforations) but not the second material. Note, however, that the first material is generally selected such that the top layer does not actually become saturated with liquid to reduce the likelihood of irritation. Instead, the top layer may allow liquid to pass therethrough into the cavities, from which the liquid can be subsequently discharged (e.g., as part of a cleaning process). The top layer and/or the bottom layer can be comprised of more than one material, such as a coated fabric or a stack of interconnected materials.

[0084] The pressure-mitigation device 500 can include a wireless power transmission system 550 configured to emit an electromagnetic field that ancillary electronic devices can extract electrical energy from. The wireless power transmission system 550 can include a wireless power source coupled to one or more power interfaces via one or more electrical conduits. The components of the wireless power transmission system 550 can be located on one or more of the top and bottom layers of the pressure-mitigation device 500 or within interconnections between the top and bottom layers of the pressure-mitigation device 500. The wireless power transmission system 550 can be located on a portion of the pressure-mitigation device 500 that makes generally less contact with the skin of the patient. For example, and as shown in Figure 5, the wireless power transmission system 550 can be located on a top portion of the pressure-mitigation device 500 above the chambers 504 such that when the chambers are inflated, the wireless power transmission system 550 makes little to no contact with the skin of the patient. It is worth noting that although the wireless power transmission system 550 is located within the boundary of the surface 502 in Figure 5, the wireless power transmission system 550 can be positioned on a part of the pressure-mitigation device 500 that does not necessarily lay flat against the surface 502. For example, and as described in more detail with reference to Figure 3, the wireless power transmission system 550 can be located on an overhang portion that hangs over and/or adheres to a side of the surface 502 that the skin of the patient does not directly contact (e.g., an arm, a side rail, underneath a seat, behind a seat, etc.). Additionally or alternatively, the wireless power transmission system 550 can be incorporated into a side support of the pressure-mitigation device 500 that is not in direct contact with the skin of the patient, as described in more detail with reference to Figures 1 A-2B and 4.

[0085] The pressure-mitigation device 500 may be designed such that inflation of at least some of the chambers 504 causes air to be continuously exchanged across the surface of the human body. Said another way, simultaneous inflation of at least some of the chambers 504 may provide a desiccating effect to inhibit generation and/or collection of moisture along the skin in a given anatomical region. In some embodiments, the pressure-mitigation device 500 is able to maintain airflow through the use of a porous material. For example, the top layer may be comprised of a biocompatible material through which air can flow (e.g., naturally or via perforations). In other embodiments, the pressure-mitigation device 500 is able to maintain airflow without the use of a porous material. For example, airflows can be created and/or permitted simply through varied pressurization of the chambers 504. This represents a new approach to microclimate management that is enabled by simultaneous inflation and deflation of the chambers 504. At a high level, each void formed beneath a human body due to deflation of at least one chamber can be thought of as a microclimate that cools and desiccates the corresponding portion of the anatomical region. Heat and humidity can lead to injury (e.g., further development of ulcers), so the cooling and desiccating effects may present some injuries due to inhibition of moisture generation/collection along the skin in the anatomical region.

[0086] As discussed below with respect to Figure 12, a pump (also referred to as a “pressure device”) can be fluidically coupled to each chamber 504 (e.g., via a corresponding valve), while a controller can control the flow of fluid generated by the pump into each chamber 504 on an individual basis in accordance with a predetermined pattern. The controller can operate the series of chambers 504 in several different ways. [0087] In some embodiments, the chambers 504 have a naturally deflated state, and the controller causes the pump to inflate at least one of the chambers 504 to shift the main pressure point along the anatomy of the human body. For example, the pump may inflate at least one chamber located directly beneath an anatomical region to momentarily apply contact pressure to that anatomical region and relieve contact pressure on the surrounding anatomical regions adjacent to the deflated chamber(s). Alternatively, the controller may cause the pump to inflate two or more chambers adjacent to an anatomical region to create a void beneath the anatomical region to shift the main pressure point at least momentarily away from the anatomical region.

[0088] In other embodiments, the chambers 504 have a naturally inflated state, and the controller may cause deflation of at least one of the chambers 504 to shift the main pressure point along the anatomy of the human body. For example, the pump may cause deflation of at least one chamber located directly beneath an anatomical region, thereby forming a void beneath the anatomical region to momentarily relieve the contact pressure on the anatomical region. To deflate a chamber, the controller may simply prevent an airflow generated by the pump from entering the chamber, as further discussed below with reference to Figures 9-10. Additionally or alternatively, the controller may cause air contained in the chamber to be released (e.g., via a release valve). At least partial deflation may naturally occur in this scenario if air escapes through the valve quicker than air enters the chamber.

[0089] Whether configured in a naturally deflated state or a naturally inflated state, the continuous or intermittent alteration of the inflation levels of the individual chambers 504 moves the location of the main pressure point across different portions of the human body. As shown in Figure 5, for example, inflating and/or deflating the chambers 504 creates temporary contact regions 506 that move across the pressure-mitigation device 500 in a predetermined pattern, thereby changing the location of the main pressure point(s) on the human body for finite intervals of time. Thus, the pressuremitigation device 500 can simulate the micro-adjustments made by healthy individuals to relieve stagnant pressure applied by the surface 502.

[0090] The series of chambers 504 may be arranged in an anatomy-specific pattern so that when the pressure of one or more chambers is altered, the contact pressure on a specific anatomical region of the human body is relieved (e.g., by shifting the main pressure point elsewhere). As an example, the main pressure point may be moved between eight different locations corresponding to the eight temporary contact regions 506, as shown in Figure 5. In some embodiments the main pressure point shifts between these locations in a predictable manner (e.g., in a clockwise or counterclockwise pattern), while in other embodiments, the main pressure point shifts between these locations in an unpredictable manner (e.g., in accordance with a random pattern or a semi-random pattern, based on the amount of force applied by the human body to the chambers, or based on the pressure of the chambers). Those skilled in the art will recognize that the number and position of these temporary contact regions 506 may vary based on the size of the pressure-mitigation device 500, the arrangement of chambers 504, the number of chambers 504, the anatomical region supported by the pressure-mitigation device 500, the characteristics of the human body supported by the pressure-mitigation device 500, the condition of the human body (e.g., whether the person is completely immobilized, partially immobilized, etc.), or any combination thereof.

[0091] Additionally, the controller can control the flow of electrical current from an external power source to the wireless power transmission system 550 on an ad hoc basis. In some embodiments, the amount of electrical current supplied to the wireless power transmission system 550 depends on the ancillary electronic devices within a predetermined proximity to the pressure-mitigation device 500. For example, the controller can recognize/detect electronic signatures of the ancillary electronic devices within three to five meters of the pressure-mitigation device 500 and transmit enough electrical current to the wireless power transmission system 550 to power at least one of the ancillary electronic devices. In some embodiments, a user can select when to supply electrical current to the wireless power transmission system 550 and/or which ancillary electronic devices to supply electrical energy to. Additionally or alternatively, the controller can determine the amount of electrical current available in the wireless power transmission system 550 and the corresponding electromagnetic field size. Depending on the size of the electromagnetic field, the controller can determine and/or automatically select which ancillary electronic devices to supply electrical energy to.

[0092] Additionally or alternatively, the controller may cause electrical energy emitted from the wireless power transmission system 550 to cease (e.g., via a circuit breaker) if electrical conditions exceed an environmental threshold that could negatively affect the patient and/or one or more components of the pressure-mitigation device 500. For example, if the wireless power source (e.g., the component that generates an electromagnetic field) exceeds a temperature threshold that would damage a top or bottom layer of the pressure-mitigation device 500, the circuit breaker can be used to dissipate the electromagnetic field.

[0093] As discussed above, the pressure-mitigation device 500 may not include side supports if the condition of a user would not benefit from the positioning assistance provided by the side supports. For example, side supports can be omitted when the user is medically immobilized (e.g., under anesthesia, in a medically induced coma, etc.) and/or physically restrained on the underlying surface 502 (e.g., by rails on the side of a bed, arm rests on the side of a chair, restraints that limit movement, etc.). In such embodiments, the wireless power transmission system 550 can be located on an overhang portion that extends from a top, bottom, and/or side portion of the pressuremitigation device 500 onto a latitudinal or longitudinal side of the surface 502.

[0094] Figure 6A is a partially schematic side view of a pressure-mitigation device 602a for relieving pressure on a specific anatomical region by deflating one or more chambers in accordance with embodiments of the present technology. The pressuremitigation device 602a can be positioned between the surface of an object 600 and a human body 604. Examples of objects 600 include elongated objects, such as mattresses, stretchers, operating tables, and procedure tables, and non-elongated objects, such as chairs (e.g., office chairs, examination chairs, recliners, and wheelchairs) and the seats included in vehicles and airplanes. To relieve the pressure on a specific anatomical region of the human body 604, at least one chamber 608a of multiple chambers (collectively referred to as “chambers 608”) proximate to the specific anatomical region is at least partially deflated to create a void 606a beneath the specific anatomical region. In such embodiments, the remaining chambers 608 may remain inflated. Thus, the pressure-mitigation device 602a may sequentially deflate chambers (or arrangements of multiple chambers) to relieve the pressure applied to the human body 604 by the surface of the object 600.

[0095] Figure 6B is a partially schematic side view of a pressure-mitigation device 602b for relieving pressure on a specific anatomical region by inflating one or more chambers in accordance with embodiments of the present technology. For example, to relieve the pressure on a specific anatomical region of the human body 604, the pressure-mitigation device 602b can inflate two chambers 608b and 608c disposed directly adjacent to the specific anatomical region to create a void 606b beneath the specific anatomical region. In such embodiments, the remaining chambers may remain partially or entirely deflated. Thus, the pressure-mitigation device 602b may sequentially inflate a chamber (or arrangements of multiple chambers) to relieve the pressure applied to the human body 604 by the surface of the object 600.

[0096] The pressure-mitigation devices 602a, 602b of Figures 6A-B are shown to be in direct contact with the object 600. However, in some embodiments, an attachment apparatus is positioned between the pressure-mitigation devices 602a, 602b and the object 600. The attachment apparatus may be designed to help secure the pressuremitigation devices 602a, 602b and the object 600. For example, the attachment apparatus may be made of a material that is naturally tacky or sticky so as to inhibit movement of the pressure-mitigation devices 602a, 602b with respect to the object 600. Alternatively, the bottom side of the pressure-mitigation devices 602a, 602b could be coated with a material, such as a removable adhesive (e.g., an elastomer- or silicone- based sealant or a pressure-sensitive film) or tacky substance (e.g., silicone rubber).

[0097] In some embodiments, the pressure-mitigation devices 602a, 602b of Figures 6A-B have the same configuration of chambers 608 and can operate in both a normally inflated state (described with respect to Figure 6A) and a normally deflated state (described with respect to Figure 6B) based on the selection of an operator (e.g., the user or some other person, such as a healthcare professional or family member). For example, the operator can use a controller to select a normally deflated mode such that the pressure-mitigation device operates as described with respect to Figure 6B and then change the mode of operation to a normally inflated mode such that the pressuremitigation device operates as described with respect to Figure 6A. Thus, the pressuremitigation devices described herein can shift the location of the main pressure point by controllably inflating chambers, controllably deflating chambers, or a combination thereof.

Overview of Controller Devices

[0098] Figures 7A-C are isometric, front, and back views, respectively, of a controller device 700 (also referred to as a “controller”) that is responsible for controlling inflation and/or deflation of the chambers of a pressure-mitigation device and transport of electrical current to a wireless power transmission system of the pressure-mitigation device in accordance with embodiments of the present technology. For example, the controller 700 can be coupled to at least one of the pressure-mitigation devices 100, 200, 300, 400 described above with respect to Figures 1 A-4 to control the pressure within the chambers and/or electrical current within the wireless power transmission system. The controller 700 can manage the pressure in each chamber of the pressuremitigation device by controllably driving one or more pumps. In some embodiments, a single pump is fluidically connected, via the controller 700, to all the chambers of the pressure-mitigation device such that the pump is responsible for generating the fluid flow to be directed to and/or from multiple chambers. In other embodiments, the controller 700 is coupled to two or more pumps, each of which can be fluidically coupled to different chambers of the pressure-mitigation device to drive inflation/deflation of those chambers. The pump(s) may reside within the housing of the controller 700 such that the system is easily transportable. Alternatively, the pump(s) may reside in a housing separate from the controller 700. In other embodiments, the controller 700 is coupled to at least one external power source that is electrically coupled to the wireless power transmission system. The controller can manage the electrical current available at the wireless power transmission system and thereby manage the electrical energy the wireless power transmission system is able to emit to ancillary electronic devices (e.g., via an electromagnetic field).

[0099] As shown in Figures 7A-C, the controller 700 can include a housing 702 in which internal components (e.g., those described below with respect to Figure 8) reside and a handle 704 that is connected to the housing 702. In some embodiments, the handle 704 is fixedly secured to the housing 702 in a predetermined orientation, while in other embodiments, the handle 704 is pivotably secured to the housing 702. For example, the handle 704 may be rotatable about a hinge connected to the housing 702 between multiple positions. The hinge may be one of a pair of hinges connected to the housing 702 along opposing lateral sides. The handle 704 enables the controller 700 to be readily transported, for example, from a storage location to a deployment location (e.g., proximate to a human body that is positioned on a surface). Moreover, the handle 704 could be used to releasably attach the controller 700 to a structure. For example, the handle 704 could be hooked on an intravenous (IV) pole (also referred to as an “IV stand” or “infusion stand”).

[00100] In some embodiments, the controller 700 includes a retention mechanism 714 that is attached to, or integrated within, the housing 702. Cords (e.g., electrical cords), tubes, and/or other elongated structures associated with the system can be wrapped around or otherwise supported by the retention mechanism 714. Thus, the retention mechanism 714 may provide strain relief and retention of an electrical cord (also referred to as a “power cord”) used to provide power to the controller 700. In some embodiments, the power cord is plugged into an external power source that can provide an electrical current supply for powering the wireless power transmission system. Additionally or alternatively, the retention mechanism 714 includes a flexible flange that can retain the plug of the electrical cord.

[00101] As further shown in Figures 7A-C, the controller 700 may include a connection mechanism 712 that allows the housing 702 to be securely, yet releasably, attached to a structure. Examples of structures include IV poles, mobile workstations (also referred to as “mobile carts”), bedframes, rails, handles (e.g., of wheelchairs), and tables. In some embodiments, the connection mechanism 712 is coupled to one or more ancillary electronic devices, such as displays used to monitor or assist with patient care but not necessarily needed for the pressure-mitigation device to function. The connection mechanism 712 may be used instead of, or in addition to, the handle 704 for mounting the controller 700 to the structure. In the illustrated embodiment, the connection mechanism 712 is a mounting hook that allows for single-hand operation and is adjustable to allow for attachment to mounting surfaces with various thicknesses. In some embodiments, the controller 700 includes an IV pole clamp 716 that eases attachment of the controller 700 to IV poles. The IV pole clamp 716 may be designed to enable quick securement, and the IV pole clamp 716 can be self-centering with the use of a single activation mechanism (e.g., knob or button).

[00102] In some embodiments, the housing 702 includes one or more input components 706 for providing instructions to the controller 700. The input component(s) 706 may include knobs (e.g., as shown in Figures 7A-C), dials, buttons, levers, and/or other actuation mechanisms. An operator can interact with the input component(s) 706 to alter the airflow provided to the pressure-mitigation device, discharge air from the pressure-mitigation device, alter electrical current provided to the wireless power transmission system, dissipate electrical current and/or electrical energy from the wireless power transmission system, or disconnect the controller 700 from the pressuremitigation device (e.g., by disconnecting the controller 700 from fluid and/or electrical tubing connected between the controller 700 and the pressure-mitigation device).

[00103] As further discussed below, the controller 700 can be configured to independently inflate and/or deflate one or more chambers of the pressure-mitigation device in a predetermined pattern specific for the pressure-mitigation device by managing one or more flows of fluid (e.g., air) produced by one or more pumps. In some embodiments, the pump(s) reside in the housing 702 of the controller 700, while in other embodiments, the controller 700 is fluidically connected to the pump(s). For example, the housing 702 may include a first fluid interface through which fluid is received from the pump(s) and a second fluid interface through which fluid is directed to the pressuremitigation device. Multi-channel tubing may be connected to either of the fluid interfaces. For example, multi-channel tubing may be connected between the first fluid interface of the controller 700 and multiple pumps.

[00104] Additionally, and as discussed further below, the controller can be configured to control the flow of electrical current to a wireless power source such that the wireless power source emits an electromagnetic field for ancillary electronic devices to extract electrical energy from. The controller 700 can be electrically coupled to an external power source that provides electrical current that can be transported to the wireless power transmission system via one or more electrical conduits. In some embodiments, the housing 702 may include a first power interface through which electrical current is received from the external power source and a second power interface through which electrical current is directed to the wireless power transmission system of the pressuremitigation device. Multi-channel tubing may be connected to either of the power interfaces.

[00105] As another example, multi-channel tubing may be connected between the second fluid interface of the controller 700 and multiple valves of the pressure-mitigation device. Additionally or alternatively, multi-channel tubing may be connected between the second power interface of the controller 700 and power interfaces of the pressuremitigation device. Here, the controller 700 includes a first fluid interface 708 and a second fluid interface 718, each of which can be designed to each interface with tubing (e.g., for single- or multi-channel fluid delivery). For example, the first fluid interface 708 may be designed for multi-channel tubing, while the second fluid interface 718 may be designed for single-channel tubing. Alternatively, the first and second fluid interfaces 708, 718 could be designed for multi-channel tubing.

[00106] In some embodiments, the first and second fluid interfaces 708, 718 restrict flow to a single direction — namely, from the controller 700 to the pressure-mitigation device(s) fluidly connected thereto — and therefore may be called “unidirectional fluid interfaces.” In other embodiments, the first and second fluid interfaces 708, 718 permit fluid flow in both directions and, therefore, may be called “bidirectional fluid interfaces.” Thus, if the first and second fluid interfaces 708, 718 are bidirectional fluid interfaces, fluid returning from a pressure-mitigation device (e.g., as part of a discharge process) may travel back to the controller 700 through either the first fluid interface 708 or the second fluid interface 718. By controlling the exhaust of fluid returning from the pressure-mitigation device, the controller 700 can actively manage the noise created during use. [00107] In some embodiments, the first fluid interface 708 and/or the second fluid interface 718 also include one or more power interfaces. Accordingly, the tubing that is connected to the first fluid interface 708, for example, could include a cable that is designed to facilitate the transmission of power (e.g., via a physical connection of electrical contacts). In such embodiments, the cable may terminate in a connector (e.g., a plug, socket, or spring-loaded contact) that is configured to mate with a corresponding power interface located in or near the first fluid interface 708. The power interface may include one or more conductive terminals, pads, or pins that are electrically connected to a power source or circuitry within the controller 700. When the tubing is connected to the first fluid interface 708, the cable’s connect can mechanically and electrically engage with the power interface, thereby establishing a conductive path for power transfer.

[00108] For example, the power interface may utilize a keyed or polarized connector to ensure proper alignment and prevent incorrect connections. The electrical contacts may be arranged in a coaxial, blade, or pin-and-socket configuration and may include features such as gold plating or spring-loaded contacts to enhance conductivity and reduce contact resistance. In some embodiments, the connection may be made automatically as the tubing is inserted, using a blind-mate connector system that does not require manual alignment by the user. Optionally, the power interface may also include sealing features (e.g., gaskets or O-rings) to maintain fluid integrity and prevent ingress of contaminants at the connection point.

[00109] In some embodiments, the power interface supports one or more additional functionalities, such as data communication or identification of the connected tubing, by incorporating additional signal lines or data contacts alongside the power conductors. The power interface may be rated for a specific voltage and current and may include safety features such as current limiting, fusing, or interlock mechanisms to prevent accidental energization when the tubing is not properly connected.

[00110] Note that, in some embodiments, the power interface may be designed for, and permit connection of, an input electrical current tube (or simply “input tube” or “input channel”) and an output electrical current tube (or simply “output tube” or “output channel”) that transport electrical current to the wireless transmission system and out of the wireless power transmission system, respectively. For example, the output tube can be connected to a resistor to cease emission of electrical energy from the pressuremitigation device in the event the electrical energy is no longer needed or an environmental threshold has been reached, as discussed herein.

[00111] While the power interfaces are described as being part of, or located near, the first and second fluid interfaces 708, 718, the controller 700 could additionally or alternatively offer an entirely separate power interface. In such embodiments, a pressure-mitigation device could be fluidly connected to the controller 700 via tubing that extends from the pressure-mitigation device to the first fluid interface 708 or second fluid interface 718 and could be electrically connected to the controller 700 via a cable that extends from a power interface accessible along the surface of the pressuremitigation device to another power interface accessible along the surface of the controller 700.

[00112] By monitoring the connections with the first and second fluid interfaces 708, 718 — or the power interface, if the power interface is separate from the first and second fluid interfaces 708, 718 — the controller 700 may be able to detect which type of pressurizable device has been connected. Each type of pressurizable device may include a different type of connector at the first fluid interface 708, second fluid interface 718, or the power interface. For example, a pressure-mitigation device designed for elongated objects (e.g., the pressure-mitigation devices 100, 200 of Figures 1 A-2B) may include a first arrangement of magnets in its connector, while a pressure-mitigation device designed for non-elongated objects may include a second arrangement of magnets in its connector. The controller 700 may include one or more sensors arranged near the first fluid interface 708 and/or the second fluid interface 718 that are able to detect whether magnets are located within a specified proximity. The controller 700 may automatically determine, based on which magnets have been detected by the sensor(s), which type of pressurizable device is connected. In some embodiments, the wireless power transmission system of a pressure-mitigation apparatus is electrically coupled to the power interface via single- or dual-channel tubing, whereas a pressure-mitigation apparatus may be fluidically coupled to the fluid interface 708 via multi-channel tubing having at least three channels through which fluid is able to flow toward a corresponding chamber. The controller 700 may be able to automatically determine which types of pressurizable devices are connected thereto simply by monitoring the first fluid interface 708 or second fluid interface 718 (e.g., to identify, for each interface, how many tubing channels are being occupied) or the power interface.

[00113] Additionally or alternatively, the controller 700 may monitor other connections proximate to the first fluid interface 708, second fluid interface 718, or power interface to identify the type of pressure-mitigation device connected. For example, some pressurizable devices may be fluidically connected to the first fluid interface 708 (and potentially the power interface, as discussed above) via cabling that includes one or more fluid or electrical current channels, as well as one or more data channels. Some pressurizable devices may be identifiable simply through the presence of these data channels, while other pressurizable devices may be identifiable based on the number or combination of the fluid channels, power channels, and/or data channels. In the event that a data channel exists, the controller 700 could also receive, via the data channel, an input that is indicative of an identification of the type of pressurizable device. Thus, the pressurizable device might indicate, to the controller 700, its type upon establishing a connection thereto. As further discussed below with reference to Figure 8, this input could also be received by the controller 700 at its communication module 808. In some embodiments, one or more of the ancillary electronic devices are fluidically and/or electrically coupled to the first fluid interface 708, second fluid interface 718, or power interface. For example, in addition to or opposed to extracting electrical energy from the wireless power transmission system, a vital sign monitoring device may receive electrical energy (e.g., in the form of electrical current) via a direct connection to the controller 700.

[00114] Pressurizable devices may have different geometries, layouts, and/or dimensions suitable for various positions (e.g., supine, prone, sitting), various supporting objects (e.g., wheelchair, bed, recliner, surgical table), and/or various user characteristics (e.g., weight, size, ailment), and the controller 700 can be configured to automatically detect the types of pressurizable devices connected thereto. In some embodiments, the automatic detection is performed using other suitable identification mechanisms, such as the controller 700 reading a radio-frequency identification (RFID) tag or barcode on the pressurizable devices. Alternatively, the controller 700 may permit an operator to specify the types of pressurizable devices connected thereto. For example, the operator may be able to select, using an input component (e.g., input component 706), a type of pressurizable device via a display 710. The controller 700 can be configured to dynamically and independently alter the pattern for inflating and/or deflating chambers based on which types of pressurizable devices are connected.

[00115] Similarly, the controller 700 may automatically detect the presence of ancillary electronic devices in proximity to the controller by reading an RFID tag or barcode on the ancillary electronic devices. Alternatively, the controller 700 may permit an operator to detect and/or select one or more ancillary electronic devices to provide electricity to. For example, the operator may use the input component 706 to select at least one ancillary electronic device to provide power to via the display 710. The controller 700 can be configured to dynamically and independently alter the amount of electrical current transferred to the wireless power transmission system based on the number and/or type of ancillary electronic devices selected.

[00116] As shown in Figures 7A-B, the controller 700 may include the display 710 for displaying information related to the pressure-mitigation device, the wireless power transmission system, and/or the user, such as the pattern of inflations/deflations, the electrical current available, the ancillary electronic devices in proximity to the pressuremitigation device, etc. For example, the display 710 may present an interface that specifies which type of pressurizable device is connected to the controller 700. As another example, the display 710 may present an interface that specifies the programmable pattern that is presently governing inflation/deflation of the pressurizable device, as well as the current state within the programmable pattern for the pressurizable device. As yet another example, the display 710 may present the size of an electromagnetic field emitted by the wireless power transmission system based on the electrical current available to transfer or currently being transferred. Other display technologies could also be used to convey information to an operator of the controller 700. In some embodiments, the controller 700 includes a series of lights (e.g., lightemitting diodes) that are representative of different statuses to provide visual alerts to the operator or the user. For example, a status light may provide a green visual indication if the controller 700 is presently providing therapy, a yellow visual indication if the controller 700 has been paused (i.e., is in a pause mode), a red visual indication if the controller 700 has experienced an issue (e.g., noncompliance of patient, patient not detected) or requires maintenance (i.e., is in an alert mode), etc. These visual indications may dim upon the conclusion of a specified period of time or upon determining that the status has changed (e.g., the pause mode is no longer active).

[00117] In some embodiments, the controller 700 includes a rapid deflate function that allows an operator to rapidly and independently deflate the pressurizable device. The rapid deflate function may be designed such that the entirety of the pressurizable device is deflated or a portion (e.g., the side supports of a pressure-mitigation device) of the pressurizable device is deflated. This may be a software-implemented solution that can be activated via the display 710 (e.g., when configured as a touch-enabled interface) and/or input components (e.g., tactile actuators such as buttons, switches, etc.) on the controller 700. This rapid deflation, in particular, the deflation of the side supports, is expected to be beneficial to operators when there is a need for quick access to the user, such as to provide cardiopulmonary resuscitation (CPR). The controller 700 can also include a rapid current cessation function that allows an operator to rapidly dissipate electrical current within the wireless power transmission system or cease the electromagnetic field emitted by the wireless power transmission system if the system exceeds some critical environmental value. Similarly, the operator can activate rapid cessation via the display 710 and/or using the input components described herein.

[00118] Figure 8 illustrates an example of a controller 800 in accordance with embodiments of the present technology. As shown in Figure 8, the controller 800 can include a processor 802, memory 804, display 806, communication module 808, manifold 810, and/or power component 812 that is electrically coupled to a power interface 814. These components may reside within a housing (also referred to as a “structural body”), such as the housing 702 described above with respect to Figures 7A- C. In some embodiments, the aspects of the controller 800 are incorporated into other components of a pressure-mitigation system. For example, some components of the controller 800 may be incorporated into a computing device (e.g., a mobile phone or a mobile workstation) that is remotely coupled to the pressurizable device and/or one or more ancillary electronic devices. Figure 8 illustrates an example of a controller 800 independently directing fluid flow into a pressure-mitigation device and electrical current flow into a wireless power transmission system of the pressure-mitigation device (in the case illustrated, a pressurizable device 832). In the example illustrated, the controller 800 independently directs fluid flow into the pressurizable device 832 via a fluid interface 830 and electrical current flow into the wireless power transmission system of the pressurizable device 832 via a power interface 835.

[00119] Each of these components is discussed in greater detail below. Those skilled in the art will recognize that different combinations of these components may be present depending on the nature of the controller 800. Other components could also be included depending on the desired capabilities of the controller 800.

[00120] For example, the controller could include one or more fragrance output mechanisms (e.g., spray pumps or spray nozzles) that are able to discharge scented fluid (e.g., air or liquid) from corresponding reservoirs so as to produce an aroma. Such a feature may be desirable if the pressurizable device is intended to be used as part of a therapy program.

[00121] As another example, the controller could include a circuitry that is able to detect and then examine electronic signatures emitted by nearby beacons or ancillary electronic devices. Accordingly, if an item (e.g., a wristband, file, device barcode, etc.) that includes a beacon is presented to the controller, the controller may be able to detect the electronic signature emitted by the beacon and then take appropriate action. For instance, the controller may determine, based on the electronic signature that conveys information regarding the human body to be treated, how to independently inflate each of the chambers of the two or more pressurizable devices. Additionally or alternatively, the controller may determine, based on the electronic signature that conveys information regarding an ancillary electronic device, how large of an electromagnetic field must be emitted (i.e., how much electrical current must be transferred to the wireless power transmission system) to power such a device. Electronic signatures may be transmitted via RFID, Bluetooth, Near Field Communication (NFC), or another short-range wireless communication protocol. Additionally or alternatively, the controller may be able to examine machine-readable codes (e.g., Quick Response codes, bar codes, and alphanumeric strings) that are printed on items such as wristbands, files, and the like. By examining the machine- readable code that is printed on an item associated with a human body, the controller may be able to determine, infer, or derive information regarding the human body. These features allow a controller to act as a “single action” solution for treating the human body since the controller may automatically begin treatment after an electronic signature or machine-readable code has been presented. Similarly, by examining the machine- readable code that is printed on an item associated with an ancillary electronic device, the controller may be able to determine, infer, or derive information regarding the ancillary electronic device. These features allow a controller to act as a “single action” solution for powering the ancillary electronic device since the controller may automatically begin transferring electrical current after an electronic signature or machine-readable code has been presented.

[00122] The processor 802 can have generic characteristics similar to general- purpose processors, or the processor 802 may be an application-specific integrated circuit (ASIC) that provides control functions to the controller 800. As shown in Figure 8, the processor 802 can be coupled to all components of the controller 800, either directly or indirectly, for communication purposes.

[00123] The memory 804 may be comprised of any suitable type of storage medium, such as static random-access memory (SRAM), dynamic random-access memory (DRAM), electrically erasable programmable read-only memory (EEPROM), flash memory, or registers. In addition to storing instructions that can be executed by the processor 802, the memory 804 can also store data generated by the processor 802 (e.g., when executing the analysis platform). Note that the memory 804 is merely an abstract representation of a storage environment. The memory 804 could be comprised of actual memory chips or modules.

[00124] The display 806 can be any mechanism that is operable to visually convey information to an operator. For example, the display 806 may be a panel that includes LEDs, organic LEDs, liquid crystal elements, or electrophoretic elements, as shown in Figures 7A-B. Alternatively, the display 806 may simply be a series of lights (e.g., LEDs) that are able to indicate the status of the controller 800. In some embodiments, the display 806 is touch sensitive. Thus, an operator or user may be able to provide input to the controller 800 by interacting with the display 806 itself. Additionally or alternatively, the operator may be able to provide input to the controller 800 by interacting with input components, such as knobs, dials, buttons, levers, and/or other actuation mechanisms.

[00125] The communication module 808 may be responsible for managing communications between the components of the controller 800, or the communication module 808 may be responsible for managing communications with other computing devices (e.g., one or more ancillary electronic devices, a mobile phone associated with the operator, a network-accessible server system accessible to an entity responsible for manufacturing, providing, or managing pressure-mitigation devices). The communication module 808 may be wireless communication circuitry that is designed to establish communication channels with other computing devices. Examples of wireless communication circuitry include integrated circuits (also referred to as “chips”) configured for Bluetooth, Wi-Fi, NFC, and the like.

[00126] Moreover, the communication module 808 may be responsible for providing information for uploading to, and retrieving information from, the electronic health record that is associated with the human body that is presently being treated. Assume, for example, that the controller 800 receives input indicating that a given person is to be treated using two or more pressurizable devices. In such a situation, the controller 800 may establish a connection with a storage medium that includes the electronic health record of the given person. In some embodiments, the controller 800 downloads information from the electronic health record into the memory 804, while in other embodiments, the controller 800 simply accesses the information in the electronic health record. This information could be used to determine how to treat the given person. For example, the controller may determine, based on the weight and age of the given person, which patterns to select for inflating each of the chambers of the pressurizable device, whether and when to adjust the patterns, etc. Additionally or alternatively, the controller 800 may be responsible for providing information for uploading to, and retrieving information from, an ancillary electronic device database that is associated with the ancillary electronic devices used to support treatment of the patient and/or healthcare professionals. For example, the controller 800 can download information regarding an ancillary electronic device identified in proximity to the controller 800 such that an appropriate electromagnetic field is generated.

[00127] The controller 800 may be connected to a pressure-mitigation device that includes a series of chambers whose pressure can be individually varied and a wireless power transmission system that can generate an electromagnetic field for ancillary electronic devices to extract electrical energy from. When the pressure-mitigation device is placed between a human body and the surface of an object, the controller 800 can independently cause the pressure on an anatomical region of the human body to be varied by controllably inflating and/or deflating chamber(s). Additionally or alternatively, the controller 800 can cause electrical current to be delivered to a wireless power source to generate the electromagnetic field. Such actions can be accomplished by the manifold 810, which controls the flow of fluid to the series of chambers of each pressure-mitigation device and the flow of electrical current to the wireless power transmission system. The manifold 810 is further described with respect to Figures 9- 1 1.

[00128] As further discussed below, transducers mounted in the manifold 810 can generate an electrical signal based on the pressure detected in each chamber of the pressurizable device. Generally, each chamber is associated with a different fluid channel and a different transducer. Accordingly, if the manifold 810 is designed to facilitate the flow of fluid to a pressurizable device with four chambers, the manifold 810 may include four fluid channels and four transducers. In some embodiments, the manifold 810 includes fewer than four fluid channels and/or transducers or more than four fluid channels and/or transducers. Pressure data representative of the values of the electrical signals generated by the transducers can be stored, at least temporarily, in the memory 804. As further discussed below, the manifold 810 may be driven based on a clock signal that is generated by a clock module (not shown). For example, the processor 802 may be configured to generate signals for driving valves in the manifold 810 (or driving integrated circuits in communication with the valves) based on a comparison of the clock signal to programmed patterns that indicate when each chamber of the two or more pressurizable devices should be independently inflated or deflated. The programmed patterns may belong to a set of multiple programmed patterns that are stored in the memory 804.

[00129] Likewise, transducers mounted in the manifold 810 can generate an electrical signal based on the electrical current in each electrical conduit of the wireless power transmission system of the pressurizable device. Generally, each electrical conduit is associated with a different power interface, electrical current channel, and transducer. Accordingly, if the manifold 810 is designed to facilitate the flow of electrical current via an input electrical current channel to an input electrical conduit and from an output electrical current conduit to an output electrical current channel, the manifold 810 may include two electrical current channels and two transducers. In some embodiments, the manifold 810 includes fewer than two electrical current channels and/or transducers or more than two electrical current channels and/or transducers. Power data, or data regarding the electrical current signals detected, can be stored in the memory 804, as described above.

[00130] An analysis platform may be responsible for examining the pressure data and/or power data. For convenience, the analysis platform is described as a computer program that resides in the memory 804. However, the analysis platform could be comprised of software, firmware, or hardware that is implemented in, or accessible to, the controller 800. In accordance with embodiments described herein, the analysis platform may include a processing module 816, analysis module 818, and graphical user interface (GUI) module 820. Each of these modules can be an integral part of the analysis platform. Alternatively, these modules can be logically separate from the analysis platform but operate “alongside” it. Together, these modules enable the analysis platform to gain insights not only into whether the pressurizable device connected to the controller 800 is being used properly but also into the health of the human body situated on or in the pressurizable device and/or into the characteristics of the ancillary electronic devices within proximity.

[00131] The processing module 816 can process pressure data obtained by the analysis platform into a format that is suitable for the other modules. For example, in preparation for analysis by the analysis module 818, the processing module 816 may apply algorithms designed for temporal aligning, artifact removal, and the like. Accordingly, the processing module 816 may be responsible for ensuring that the pressure data is accessible to the other modules of the analysis platform. As further discussed below, the processor 802 may forward at least some of the pressure data, in either its processed or unprocessed form, to the communication module 808 for transmission to a destination for analysis. In such a scenario, the processing module 816 may apply operations (e.g., filtering, compressing, labeling) to the pressure data before it is forwarded to the communication module 808 for transmission to the destination.

[00132] By examining the pressure data in conjunction with flow data representative of the fluid flowing into the controller 800 from the pump(s), the analysis module 818 can control how the chambers of the pressurizable device 832 are inflated and/or deflated. For example, the analysis module 818 may be responsible for separately and independently controlling the set point for fluid flowing into each chamber such that the pressures of the chambers match a predetermined pattern for the pressurizable device.

[00133] By examining the pressure data, the analysis module 818 may also be able to discover, predict, or otherwise determine characteristics of the living body to which the pressurizable device 832 provides treatment. For example, the analysis module 818 may be able to sense movements of the human body under which a pressurizable device (e.g., pressure-mitigation device 100 of Figures 1 A-B) is positioned. These movements may be caused by the user, another individual (e.g., a caregiver or an operator of the controller 800), or the underlying surface. The analysis module 818 may apply algorithms to the data representative of these movements (also referred to as “movement data” or “motion data”) to identify repetitive movements and/or random movements to better understand the health state of the user. For example, the analysis module 818 may be able to produce a coverage metric indicative of the amount of time that the human body is properly positioned on or in each pressurizable device. As further discussed below, the controller 800 (or another computing device) may be able to independently establish whether each pressurizable device has been properly deployed and/or operated based on the coverage metric. As another example, the analysis module 818 may be able to establish the respiration rate, heart rate, or another vital measurement based on the movements of the user. Generally, the movement data is derived from the pressure data. That is, the analysis module 818 may be able to infer movements of the human body by analyzing the pressure of the chambers of each of the pressurizable devices in conjunction with the rate at which fluid is being delivered to those chambers. Consequently, some embodiments of each of the pressurizable devices may not actually include any sensors for measuring movement, such as accelerometers, tilt sensors, or gyroscopes.

[00134] Similarly, the controller 800 may examine the power data with flow data representative of the electrical current flowing into the controller 800 from the external power source to control the electromagnetic field emitted by the wireless power transmission system. By examining the power data, the analysis module 818 may also be able to discover, predict, or otherwise determine characteristics of the ancillary electronic devices to which the wireless power transmission system of the pressurizable device 832 is providing electrical energy. For example, the analysis module 818 may be able to predict the remaining operation time available for an ancillary electronic device extracting electrical energy from the wireless power transmission system.

[00135] The analysis module 818 may respond in several ways after examining the pressure data. For example, the analysis module 818 may generate a notification (e.g., an alert) to be transmitted to another computing device by the communication module 808. The other computing device may be associated with a medical professional (e.g., a physician or a nurse), a caregiver (e.g., a family member or friend of the user), or some other entity (e.g., a researcher or an insurer). As another example, the analysis module 818 may cause the pressure data (or analyses of such data) to be integrated with the electronic health record of the user. Generally, the electronic health record is maintained in a storage medium that is accessible to the communication module 808 across a network. Similarly, the analysis module 818 may cause the power data (or analysis of such data) to be integrated into the ancillary electronic device database.

[00136] Note that, in some embodiments, the analysis module 818 is also responsible for ensuring that the pressurizable device 832 is either sequentially or simultaneously controlled in a logical manner. For example, if the controller is responsible for managing electrical current flow into the wireless power transmission system, it may be desirable for the analysis module 818 to coordinate that electrical current flow with fluid flow into the pressure-mitigation device to reduce the likelihood of interference. As a specific example, the analysis module 818 may indicate — to the processor 802 — that electrical current flow into the wireless power transmission system should stop entirely when pressurized fluid flow into the pressurizable device 832 is initiated. Accordingly, the analysis module 818 may manipulate flow of electrical current based on a programmed pattern indicating how fluid should flow into the pressure-mitigation device.

[00137] The GUI module 820 may be responsible for generating interfaces that can be presented on the display 806. Various types of information can be presented on these interfaces. For example, information that is calculated, derived, or otherwise obtained by the analysis module 818 may be presented on an interface for display to the user or operator. As another example, visual feedback may be presented on an interface so as to indicate whether the user is properly situated on or in the pressurizable device. As yet another example, visual feedback may be presented on the interface so as to indicate whether the at least one ancillary electronic device is extracting electrical energy from the wireless power transmission system.

[00138] The controller 800 may include a power component 812 that is able to provide power to the other components residing within the housing, as necessary. Examples of power components include rechargeable lithium-ion (Li-ion) batteries, rechargeable nickel-metal hydride (NiMH) batteries, rechargeable nickel-cadmium (NiCad) batteries, etc. In some embodiments, the controller 800 does not include a power component and, thus, must receive power from an external source. In such embodiments, a cable designed to facilitate the transmission of power (e.g., via a physical connection of electrical contacts) may be connected between the power interface 814 of the controller 800 and the external source. The external source may be, for example, an alternating current (AC) power socket or another computing device. The cable connected to the power interface 814 of the controller 800 may also be able to convey power so as to recharge the power component 812. Additionally or alternatively, the cable connected to the power interface 814 may be able to convey power to the electrical interface electrically coupled to the wireless transmission system of the pressurizable device 832.

[00139] Embodiments of the controller 800 can include any subset of the components shown in Figure 8, as well as additional components not illustrated here.

[00140] For example, while the controller 800 is able to receive and transmit data wirelessly via the communication module 808, other embodiments of the controller 800 may include a physical data interface through which data can be transmitted to another computing device. Examples of physical data interfaces include Ethernet ports, Universal Serial Bus (USB) ports, and proprietary ports.

[00141] As another example, some embodiments of the controller 800 include an audio output mechanism 822 and/or an audio input mechanism 824. The audio output mechanism 822 may be any apparatus that is able to convert electrical impulses into sound. One example of an audio output mechanism is a loudspeaker (or simply “speaker”). Meanwhile, the audio input mechanism 824 may be any apparatus that is able to convert sound into electrical impulses. One example of an audio input mechanism is a microphone. Together, the audio output and input mechanisms 822, 824 may enable the user or operator to engage in an audible exchange with a person who is not located proximate to the controller 800. Assume, for example, that the user is misaligned on a pressure-mitigation device that is treating her or the battery of a vitals- monitoring device has gone dead. In such a scenario, the user may utilize the audio input mechanism 824 to verbally ask for assistance, for example, from another person who is able to verbally confirm that assistance is forthcoming using the audio output mechanism 822. The other person could be a medical professional or caregiver of the user. This may be useful in situations where the user is unable to reposition herself on or in the pressure-mitigation device or get up from the pressure-mitigation device due to an underlying condition that inhibits or prevents movement.

[00142] The audio input mechanism 824 may also be able to generate a signal that is indicative of more nuanced sounds. For example, the audio input mechanism 824 may generate data that is representative of sounds originating from within the human body situated on or in the pressurizable device 832. These sounds may be representative of auscultation sounds generated by the circulatory, respiratory, and gastrointestinal systems. This data could be transmitted (e.g., by the communication module 808) to a destination for analysis.

[00143] Other sensors may also be implemented in, or accessible to, the controller 800. For example, sensors may be contained in the housing of the controller 800 and/or embedded within the pressurizable device 832. Collectively, these sensors may be referred to as the “sensor suite” 826. For example, the sensor suite 826 may include a motion sensor whose output is indicative of the motion of the controller 800 or the pressurizable device 832. Examples of motion sensors include multi-axis accelerometers and gyroscopes. As another example, the sensor suite 826 may include a proximity sensor whose output is indicative of proximity to the controller 800 or pressurizable device 832. A proximity sensor may include, for example, an emitter that is able to emit infrared (IR) light and a detector that is able to detect reflected IR light that is returned toward the proximity sensor. These types of proximity sensors are sometimes called laser imaging, detection, and ranging (LiDAR) scanners. Proximity sensors may be especially useful in detecting ancillary electronic devices near the controller and/or the pressurizable device 832. Other examples of sensors include an ambient light sensor whose output is indicative of the amount of light in the ambient environment, a temperature sensor whose output is indicative of the temperature of the ambient environment, and a humidity sensor whose output is indicative of the humidity of the ambient environment. The output(s) produced by the sensor suite 826 may provide greater insight into the environment in which the controller 800 is deployed (and thus the environment in which the human body situated on or in the pressurizable device is to be treated). Additionally or alternatively, the sensor suite 826 can provide insight into the environment throughout treatment using the pressurizable device. For example, if humidity at the portion of the pressurized device where the wireless transmission system is located exceeds a humidity threshold, the controller 800 can cease flow of electrical current. In some embodiments, the sensor suite 826 includes sensors for an electromagnetic field (EMF) meter that can measure electric, magnetic, and RF fields generated by the wireless power transmission system.

[00144] In some embodiments, the sensor suite 826 includes one or more specialty sensors that are designed to generate, obtain, or otherwise produce information related to the health of the human body. For example, the sensor suite 826 may include a vascular scanner. The term “vascular scanner” may be used to refer to an imaging instrument that includes (i) an emitter operable to emit electromagnetic radiation (e.g., in the near infrared range) into the body and (ii) a sensor operable to sense electromagnetic radiation reflected by physiological structures inside the human body. Normally, an image is created based on the reflected electromagnetic radiation that serves as a reference template for the vasculature of an anatomical region. Thus, the vasculature in an anatomical region could be periodically or continually monitored based on outputs produced by a vascular scanner included in the sensor suite 826.

Additionally or alternatively, the sensor suite 826 may include sensors that are designed to perform pulse oximetry by determining oxygen level of the blood, measuring blood pressure, computing heart rate, etc.

[00145] Based on the output(s) produced by the sensor suite 826, the controller 800 (or some other computing device) may be able to compute some or all of the main vital signs— namely, body temperature, blood pressure, pulse rate, and breathing rate (also referred to as “respiratory rate”). Moreover, the controller 800 (or some other computing device) may be able to compute metrics that are indicative of the health of the human body despite not being one of the main vital signs. For example, output(s) generated by the sensor suite 826 could be used to establish whether the human body is performing a given activity (e.g., sleeping or eating). The output(s) could be used to ascertain not only the sleep pattern of the human body but also whether changes in the sleep pattern indicate whether the health state of the human body has improved (e.g., sleep more consistent with longer duration following deployment of a pressure-mitigation device).

[00146] Note that the sensors included in the sensor suite 826 need not necessarily be included in the controller 800. For example, the controller 800 may be communicatively connected to ancillary sensors that are included in various items (e.g., blankets and clothing), attached to the human body, etc.

[00147] These various components may allow the controller 800 to be readily integrated into a network-connected environment, such as a home or hospital. Thus, the controller 800 may be communicatively coupled to mobile phones, tablet computers, wearable electronic devices (e.g., fitness trackers and watches), or network-connected devices (also referred to as “smart devices”), such as televisions and home assistant devices. Similarly, the controller 800 may be communicatively coupled to medical devices, such as cardiac pacemakers, insulin pumps, glucose monitoring devices, and the like. In some embodiments, the wireless power transmission system is capable of wirelessly providing power to one or more of the medical devices communicably coupled to the controller 800, reducing the cables within the treatment area and making patients generally more accessible to operators. Additionally, if the medical devices are battery powered, the wireless power transmission system can reduce the number of times that operators must replace batteries or switch out ancillary electronic devices, allowing the operator more time to focus on treatment of the patient. This level of integration can provide several notable benefits over conventional technologies for mitigating pressure.

[00148] As an example, the pressure-mitigation system of which the controller 800 is a part may be used to monitor health of a human body in a more holistic sense. As mentioned above, insights into movements of the human body can be surfaced through analysis of pressure data generated by the controller 800 or pressurizable devices. Analysis of these movements over an extended period of time (e.g., days, weeks, or months) may lead to the discovery of abnormalities that might otherwise go unnoticed. For example, the controller 800 (or some other computing device) may infer that the human body is suffering from an ailment in response to a determination that its movements over a recent interval of time differ from those that would be expected based on past intervals of time. At a high level, insights gained through analysis of the pressure data can be used not only to define a “health baseline” for the human body but also to discover when deviations from the health baseline occur.

[00149] As another example, the controller 800 may be responsible for providing or supplementing prompts to administer medication in accordance with a regimen. Assume, for example, that a user positioned on or in the pressurizable device 832 is associated with a regimen that requires a medication to be administered regularly. The controller 800 may promote adherence to the regimen by prompting the user or another person (e.g., an operator of the controller 800) to administer the medication. Visual notifications could be presented by the display 806, or audible notifications could be presented by the audio output mechanism 822. Additionally or alternatively, the controller 800 could cause digital notifications (also referred to as “electronic notifications”) to be presented by a computing device that is communicatively coupled to the controller 800. In some embodiments, the regimen is stored in the memory 804 of the controller 800. In other embodiments, the regimen is stored in the memory of a computing device that is communicatively coupled to the controller 800. For example, the regimen may be implemented by a computer program that is executing on a mobile device associated with the user, and when the computer program determines that a dose of the medication is due to be administered, the computer program may transmit an instruction to the controller 800 to generate a notification.

[00150] Similarly, the controller 800 may be responsible for detecting ancillary electronic devices within proximity that are on low battery or in need of additional electrical energy. The controller 800 can further be responsible for initiating the transfer of electrical current to the wireless power transmission system such that the wireless power transmission system can generate an electromagnetic field. Additionally or alternatively, the controller 800 may prompt the user or another person to initiate the transfer of electrical current. In some embodiments, the wireless power transmission system may be already generating an electromagnetic field. In such embodiments, the controller 800 can automatically initiate extraction of electrical energy by the ancillary electronic device(s). Additionally or alternatively, the controller 800 can provide a visual notification to the user to initiate extraction of electrical energy by the ancillary electronic device(s), as described above.

[00151] As another example, the controller 800 may be able to facilitate communication with medical professionals. Assume, for example, that the controller 800 is deployed in a home environment that medical professionals visit infrequently or not at all. In such a scenario, the controller 800 may allow the user to communicate with medical professionals who are located outside of the home environment. Thus, the user may be able to communicate, via the audio output and input mechanisms 822, 824, with medical professionals who are located in a hospital environment (e.g., at which the user received treatment) or their own home environments.

[00152] As another example, the controller 800 may be able to facilitate communication with emergency services. For instance, if the controller 800 determines (e.g., through analysis of pressure data) that no movement has occurred for a predetermined amount of time, the controller 800 may prompt the user to respond. Similarly, if the controller 800 receives input from the user indicative of a request for assistance, the controller 800 may initiate communication with emergency services. Thus, the controller 800 may be programmed to perform some action if, for example, it determines (e.g., through analysis of the signal generated by the audio input mechanism 824) that the user has indicated she has fallen or has experienced a medical event (e.g., shortness of breath, heart palpitations, excessive sweating).

[00153] These benefits allow pressure-mitigation systems to be deployed in situations where frequent visits by medical professionals may not be practical or possible. For example, when deployed in a hospital environment, a pressure-mitigation system with a wireless power transmission system may allow medical professionals to visit patients less frequently. For example, medical professionals may not need to continually check on patients if pressure-mitigation systems are able to autonomously discover changes in health and/or if one or more ancillary electronic devices in the proximity of the controller need to be charged. As another example, when deployed in a home environment, a pressure-mitigation system may be able to counter a lack of visits from medical professionals. If a patient is instructed to situate herself on the pressuremitigation device or pair the ancillary electronic devices to the pressure-mitigation system while at home, the patient may only need to be visited every few (e.g., three, five, or seven) days rather than once per day or multiple times per day. Overall, implementing pressure-mitigation systems can lead to significant cost savings because medical professionals are required to make visits less frequently, perform fewer medical procedures, and replace ancillary electronic devices less frequently and because patients can be discharged more quickly.

[00154] The controller 800 may also be designed to focus on wellness in addition to, or instead of, treatment for (and prevention of) pressure-induced injuries. As an example, embodiments of the controller 800 may be designed to aid in sleep management for healthy individuals and/or unhealthy individuals. Using the audio output mechanism 822 in combination with the manifold 810, the controller 800 may be able to accomplish tasks such as simulating the presence of another person, for example, by producing vocal sounds, breathing sounds, applying pressure, and the like.

[00155] Figure 9 is an isometric view of a manifold 900 for controlling the flow of fluid (e.g., air) to the chambers of a pressure-mitigation device and electrical current flow to a wireless transmission system of the pressure-mitigation device in accordance with embodiments of the present technology. As discussed above, a controller can be configured to inflate and/or deflate the chambers of a pressure-mitigation device to create a pressure gradient that moves the main point of pressure applied by an object across the surface of a human body situated on the pressure-mitigation device. To accomplish this, the manifold 900 can guide fluid to the chambers through a series of valves 902. In some embodiments, each valve 902 corresponds to a separate chamber of the pressure-mitigation device. In some embodiments, at least one valve 902 corresponds to multiple chambers of the pressure-mitigation device. In some embodiments, at least one valve 902 is not used during operation. For example, if the pressure-mitigation device includes four chambers, multi-channel tubing may be connected between the pressure-mitigation device and four valves 902 of the manifold 900. In such embodiments, the other valves may remain sealed during operation.

[00156] Additionally or alternatively, the controller can be configured to detect ancillary electronic devices within a predetermined proximity and initiate generation of an electromagnetic field for the ancillary electronic devices to extract electrical energy from. To accomplish this, the manifold 900 can guide electrical current through a series of power interfaces 912. In some embodiments, the power interfaces 912 correspond to a separate electrical conduit of the wireless power transmission system. For example, one of the power interfaces 912 can be an input power interface that electrically couples an input electrical conduit and the other power interface 912 can be an output power interface that electrically couples an output electrical conduit.

[00157] Generally, the valves 902 are piezoelectric valves designed to switch from one state (e.g., an open state) to another state (e.g., a closed state) in response to an application of voltage. Each piezoelectric valve includes at least one piezoelectric element that acts as an electromechanical transducer. When a voltage is applied to the piezoelectric element, the piezoelectric element is deformed, thereby resulting in mechanical motion (e.g., the opening or closing of a valve). Examples of piezoelectric elements include disc transducers, bender actuators, and piezoelectric stacks.

[00158] Piezoelectric valves provide several benefits over other valves, such as linear valves and solenoid-based valves. First, piezoelectric valves do not require holding current to maintain a state. As such, piezoelectric valves generate almost no heat. Second, piezoelectric valves create almost no noise when switching between states, which can be particularly useful in medical settings. Third, piezoelectric valves can be opened and closed in a controlled manner that allows the manifold 900 to precisely approach a desired flow rate without overshoot or undershoot. In contrast, the other valves described above must be in either an open state, in which the valve is completely open, or a closed state, in which the valve is completely closed. Fourth, piezoelectric valves require very little power to operate, so a power component (e.g., power component 812 of Figure 8) may only need to provide 3-6 watts to the manifold 900 at any given time. While embodiments of the manifold 900 may be described in the context of piezoelectric valves, other types of valves, such as linear valves or solenoid-based valves, could be used instead of, or in addition to, piezoelectric valves.

[00159] In some embodiments, the manifold 900 includes one or more transducers 906 and a circuit board 904 that includes one or more chips for managing communication with the valves 902 and the transducer(s) 906. Because these local chip(s) reside within the manifold 900 itself, the valves 902 can be digitally controlled in a precise manner. The local chip(s) may be connected to other components of the controller. For example, the local chip(s) may be connected to other components housed within the controller, such as processors (e.g., processor 802 of Figure 8) and clock modules. The transducer(s) 906, meanwhile, can generate an electrical signal based on the pressure of each chamber of the pressure-mitigation device. Generally, each chamber is associated with a different valve 902 and a different transducer 906. Here, for example, the manifold includes six valves 902 capable of interfacing with the pressure-mitigation device, and each of these valves may be associated with a corresponding transducer 906. Pressure data representative of the values of the electrical signals generated by the transducer(s) 906 can be provided to other components of the controller for further analysis.

[00160] The power interfaces 912 can, similarly, include a first state (e.g., an off-state) that switches to another state (e.g., an on-state). As an example, the power interfaces 912 can include one or more transducers 916 (e.g., current transducers). The transducers 916 can include switches that allow for opening and/or closing of a secondary circuit when a threshold is detected by sensors paired with the transducer. The secondary circuit can control flow of electrical current into the power interfaces 912. For example, if electrical current is flowing to the wireless power transmission system and a sensor detects an environmental change over a certain threshold, a switch in the secondary circuit of the transducer 916 can flip to an off-state that opens an electrical circuit and prevents electrical current from flowing into the wireless power transmission system. In some embodiments, switching the circuit to an off-state also triggers any electrical current already in the wireless power transmission system and/or the electromagnetic field generated to be ceased, for example, by sending any remaining electrical current out of the wireless power transmission system through an output electrical conduit. Additionally, the transducers 916 can switch to an on-state (i.e., by closing the secondary circuit) to initiate electrical current flow through the power interfaces 912 and into the wireless power transmission system. In some embodiments, the secondary circuit is located on the circuit board 904.

[00161] As another example, the power interfaces 912 and/or the transducers 916 can include toggle switches that, in an off-state, cause an open circuit at a secondary circuit, preventing electrical current from flowing to the wireless power transmission system from the power interface 912. The toggle switches can include a lever that a user or operator can flip to switch the power interfaces 912 to an on-state (i.e., closing the circuit and allowing electrical current to flow to the wireless power transmission system). In some embodiments, the power interfaces 912 and/or the transducers 916 include other types of switches, such as push-button switches, rotary switches, or magnetically operated switches instead of, or in addition to, the toggle switches.

[00162] In addition to the valves 902 and transducer(s) 906, the transducers 916 can couple the circuit board 904 with local chip(s) for managing communication with the power interfaces 912 and the transducer(s) 916. The transducer(s) 916 can generate an electrical signal based on the electrical current within the wireless power transmission system and/or the size of the electromagnetic field emitted from the wireless power transmission system. Generally, each electrical conduit is associated with a different power interface 912 and a different transducer 916. Here, for example, the manifold includes two power interfaces 912 interfacing with the pressure-mitigation device, and each of these power interfaces 912 may be associated with a corresponding transducer 916. Power data (e.g., data from the power interface 912) represented as electrical signals generated by the transducer(s) 916 can be provided to other components of the controller for further analysis.

[00163] The manifold 900 may also include one or more compressors, for example, for controlling the flow of fluid to the chambers of the pressure-mitigation device. In some embodiments, each valve 902 of the manifold 900 is fluidically coupled to the same compressor, while in other embodiments, each valve 902 of the manifold 900 is fluidically coupled to a different compressor. Each compressor can increase the pressure of fluid by reducing its volume before guiding the fluid to the pressuremitigation device.

[00164] Fluid produced by a pump may initially be received by the manifold 900 through one or more ingress fluid interfaces 908 (or simply “ingress interfaces”). As noted above, in some embodiments, a compressor may then increase pressure of the fluid by reducing its volume. Thereafter, the manifold 900 can controllably guide the fluid into the chambers of a pressure-mitigation device through the valves 902. The flow of fluid into each chamber can be controlled by local chip(s) disposed on the circuit board 904. For example, the local chip(s) can dynamically vary the flow of fluid into each chamber in real time by controllably applying voltages to open/close the valves 902.

[00165] In some embodiments, the manifold includes one or more egress fluid interfaces 910 (or simply “egress interfaces”). The egress fluid interface(s) 910 may be designed for high pressure and high flow to permit rapid deflation of the pressuremitigation device. For example, upon determining that an operator has provided input indicative of a request to deflate the pressure-mitigation device (or a portion thereof), the manifold 900 may allow fluid to travel back through the valve(s) 902 from the pressure-mitigation device and then out through the egress fluid interface(s) 910. Thus, the egress fluid interface(s) 910 may also be referred to as “exhausts” or “outlets.” To provide the input, the operator may interact with a mechanical input component (e.g., mechanical input component 706 of Figure 7A) or a digital input component (e.g., visible on display 710 of Figure 7A).

[00166] Similarly, electrical current from an external source may initially be received by the manifold 900 through one or more ingress power interfaces 918 (or simply “ingress interfaces”). In some embodiments, a current amplifier or a current attenuator can be used to increase or decrease the initial electrical current received, respectively. For example, the circuit board 904 can include a current attenuator that decreases the electrical current provided from the external power source to a range safer for being near a patient. Thereafter, the manifold 900 can introduce electrical current into the wireless power transmission system of the pressure-mitigation device through the power interface(s) 912. The flow of electrical current into each chamber can be controlled by local chip(s) disposed on the circuit board 904. For example, the local chip(s) can dynamically vary the flow of electrical current into the electrical conduits of the wireless power transmission system in real time by switching a switch from an off- state to an on-state.

[00167] In some embodiments, the manifold includes one or more egress power interfaces 920 (or simply “egress interfaces”). The egress power interface(s) 920 may be designed for discharging electrical current from the wireless power transmission system, for example, through a discharge path including a resistor or similar load. The egress power interface(s) 920 permits cessation of electrical energy from the wireless power transmission system. For example, upon determining that an operator has provided input indicative of a request to cease emission of the electromagnetic field from the wireless power transmission system (or a portion thereof), the manifold 900 may allow electrical current from the wireless power transmission system to travel back through the power interface(s) 912 and then out through the egress power interface(s) 920. To provide the input, the operator may interact with a mechanical input component or a digital input component of the controller, as described above. Additionally or alternatively, the pressure-mitigation device can include an external circuit breaker that causes electrical current in the wireless power transmission system to cease.

[00168] Figure 10 is a generalized electrical diagram illustrating how the piezoelectric valves 1002 of a manifold can separately control the flow of fluid along multiple channels in accordance with embodiments of the present technology. In Figure 10, the manifold includes seven piezoelectric valves 1002. Other embodiments of the manifold may include fewer than seven valves or more than seven valves. Fluid, such as air, can be guided by the manifold through the piezoelectric valves 1002 to the chambers of a pressure-mitigation device. In Figure 10, the manifold is fluidically connected to a pressure-mitigation device that has five chambers. However, in other embodiments, the manifold may be fluidically connected to a pressure-mitigation device that has fewer than five chambers or more than five chambers.

[00169] All of the piezoelectric valves 1002 included in the manifold need not necessarily be identical to one another. Piezoelectric valves may be designed for high pressure and low flow, high pressure and high flow, low pressure and low flow, or low pressure and high flow. In some embodiments, all of the piezoelectric valves included in the manifold are the same type, while in other embodiments, the manifold includes multiple types of piezoelectric valves. For example, piezoelectric valves corresponding to side supports of the pressure-mitigation device may be designed for high pressure and high flow (e.g., to allow for a quick discharge of fluid stored therein), while piezoelectric valves corresponding to chambers of the pressure-mitigation device may be designed for high pressure and low flow. Moreover, some piezoelectric valves may support bidirectional fluid flow, while other piezoelectric valves may support unidirectional fluid flow. Generally, if the manifold includes unidirectional piezoelectric valves, each chamber in the pressure-mitigation device is associated with a pair of unidirectional piezoelectric valves to allow fluid flow in either direction. Here, for example, Chambers 1 -3 are associated with a single bidirectional piezoelectric valve, Chamber 4 is associated with two bidirectional piezoelectric valves, and Chamber 5 is associated with two unidirectional piezoelectric valves.

[00170] The chambers of a pressure-mitigation device may be inflated/deflated for a predetermined duration of 15-180 seconds (e.g., 30 seconds, 60 seconds, 90 seconds, 120 seconds, 150 seconds, or any duration therebetween) in accordance with a predetermined pattern. Thus, the status of each chamber may be varied at least every 60 seconds, 90 seconds, 120 seconds, 240 seconds, etc. Generally, the predetermined pattern causes the chambers to be inflated/deflated in a nonidentical manner. For example, if the pressure-mitigation device includes four chambers, the first and second chambers may be inflated for 30 seconds, the second and third chambers may be inflated for 45 seconds, the third and fourth chambers may be inflated for 30 seconds, and then the first and fourth chambers may be inflated for 45 seconds. These chambers may be inflated/deflated to a predetermined pressure level from 0-100 millimeters of mercury (mmHg) (e.g., 15 mmHg, 20 mmHg, 30 mmHg, 45 mmHg, 50 mmHg, or any pressure level therebetween). In some embodiments, the inflation pattern administered by the controller inflates/deflates two or more chambers at one time. In these embodiments, the chambers can be inflated/deflated to the same or different pressure levels, and the duration that the chambers are maintained at the pressure levels may be the same or different. For example, in the scenario above where the first and second chambers are inflated, the first chamber may be inflated to a pressure of 15 mm Hg, while the second chamber may be inflated to a pressure of 30 mm Hg. In other embodiments, the controller can apply different inflation/deflation patterns to the individual chambers.

[00171] Figure 11 is a generalized electromagnetic field diagram illustrating how electrical current flowing in and out of an electrically powered transmitter device 1152 can generate an electromagnetic field 1 125 in accordance with embodiments of the present technology. In Figure 11 , an electrical current can be input into a transmitter system 1150 (also referred to as a “wireless power transmission system”) via an input power interface 1154. The power interface 1 154 can be electrically coupled to the electrically powered transmitter device 1152 (also referred to herein as the “wireless power source”). For example, an input electrical conduit can electrically couple the power interface 1154 on one end and the electrically powered transmitter device 1 152 at another end such that electrical current can travel through the electrically powered transmitter device 1152. In some embodiments, the power interfaces 1 154 are on a pressure-mitigation device, as described herein. Additionally or alternatively, the power interfaces 1 154 can be electrically coupled to one or more power interfaces on a manifold of a controller (e.g., the power interfaces 912 on the manifold 900 of Figure 9). Here, a manifold that includes two power interfaces would be connected to a pressuremitigation device that has two power interfaces (e.g., the power interfaces 1 154) — for example, an input power interface and an output power interface. Other embodiments of the manifold and/or the pressure-mitigation device may include fewer than two power interfaces or more than two power interfaces. Electrical current can be guided by the manifold to the power interfaces 1154 to the electrically powered transmitter device 1 152 and back.

[00172] In some embodiments, the electrically powered transmitter device 1152 is one or more coils, pads, mats, discs, antennas, and/or devices that can emit an electromagnetic field after receiving an electrical current. In Figure 11 , the electrically powered transmitter device 1 152 is a coil. When electrical current (e.g., an alternating current) travels through the coil (e.g., a conductor), a changing magnetic field is created around the coil. As shown in Figure 1 1 , the electromagnetic field 1 125 generated around the coil alternates in strength and direction. The size of the electromagnetic field 1 125 can depend on the strength of the alternating current and/or the number of rotations the coil includes. Inducing the electromagnetic field 1 125 can induce an electromotive force (emf), and the emf can induce an alternating current in the circuitry of the one or more ancillary electronic devices in a predetermined proximity. In some embodiments, the alternating current is converted to a direct current, providing electrical energy to the ancillary electronic device. Additionally or alternatively, the coil illustrated can be placed near a magnet that changes the magnetic flux running through the coil, inducing the emf and creating the time-varying electromagnetic field 1125.

[00173] In some embodiments, the electromagnetic field 1125 generated can be dissipated by directing the electrical current out of the transmitter system 1150. For example, the transmitter system 1150 can include an output power interface 1154 that is electrically coupled to a discharge resistor and/or a ground that dissipates the electrical energy from the transmitter system 1150. Additionally or alternatively, the time-varying electromagnetic field generated from the input electrical current can naturally decay over time if no capacitors and/or inductive elements are active in the transmitter system 1150 and no more electrical current is input into the transmitter system 1150.

Overview of Pressure-Mitigation Systems with Wireless Power Transmission System

[00174] Figure 12 is a partially schematic side view of a pressure-mitigation system 1200 (or simply “system”) for orienting a patient 1202 (also referred to as a “user”) over a pressure-mitigation device 1206 in accordance with embodiments of the present technology. Here, the system 1200 includes a pressure-mitigation device 1206 that include side supports 1208, an attachment device 1204, a pressure device 1214, and a controller 1212. Other embodiments of the system 1200 may include a subset of these components. For example, the system 1200 may include a pressure-mitigation device 1206, a pressure device 1214, and a controller 1212. The pressure-mitigation device 1206 is discussed in further detail with respect to Figures 1 A-4, and the controller 1212 is discussed in further detail with respect to Figures 7A-11 . The pressure-mitigation device 1206 includes a series of chambers interconnected on a base material that may be arranged in a geometric pattern designed to mitigate the pressure applied to an anatomical region by the surface of an object (e.g., here, hospital equipment 1216).

[00175] In this embodiment, the pressure-mitigation device 1206 includes a pair of elevated side supports 1208 that extend longitudinally along opposing sides of the pressure-mitigation device 1206. The elevated side supports 1208 can include a wireless power transmission system 1222 that ancillary electronic devices 1218 can extract electrical energy from. The wireless power transmission system 1222 can be positioned on or within the side support 1208 on a face facing away from the skin of the user 1202 (e.g., an outer side wall or an upper face of the side support 1208) such that heat radiated from the wireless power transmission system 1222 has little to no effect on the user 1202, decreasing the likelihood of patient harm or discomfort. Additionally or alternatively, the pressure-mitigation device 1206 can include a pair of elevated side supports that are deployed on the surface of the object (e.g., the hospital equipment 1216) or no elevated side supports. In such embodiments, the pressure-mitigation device 1206 may include an overhang portion, as discussed in more detail with reference to Figure 3, to position the wireless power transmission system 1222 on a portion of the pressure-mitigation device 1206 that has generally less contact with the skin of the patient.

[00176] The elevated side supports 1208 can be configured to actively orient the anatomical region of the user 1202 over the series of chambers. For example, the elevated side supports 1208 may be responsible for actively orienting the anatomical region widthwise over the epicenter of the geometric pattern. As shown in Figure 12, the anatomical region may be the sacral region. However, the anatomical region could be any region of the human body that is susceptible to pressure. The elevated side supports 1208 may be configured to be ergonomically comfortable. For example, the elevated side supports 1208 may include a recess designed to accommodate the forearm that permits pressure to be offloaded from the elbow. The elevated side supports 1208 may be significantly larger in size than the chambers of the pressure- mitigation device 1206. Accordingly, the elevated side supports 1208 may create a barrier that restricts lateral movement of the user 1202. In some embodiments, the elevated side supports 1208 are approximately two to three inches taller in height as compared to the average height of an inflated chamber. Because the elevated side supports 1208 straddle the user 1202, the elevated side supports 1208 can act as barriers for maintaining the position of the user 1202 on top of the pressure-mitigation device 1206. As discussed above, the elevated side supports 1208 may be omitted in some embodiments. For example, the elevated side supports 1208 may be omitted if the user 1202 suffers from impaired mobility due to physical injury, structural components that limit movement, anesthesia, or some other condition that limits natural movement. In such embodiments, the pressure-mitigation device can include an overhang portion that positions the wireless power transmission system in a manner that makes little to no contact with the skin of the patient.

[00177] In some embodiments, the inner side walls of the elevated side supports 1208 form, following inflation, a firm surface at a steep angle of orientation with respect to the pressure-mitigation device 1206. For example, the inner side walls may be on a plane of approximately 1 15 degrees, plus or minus 24 degrees, from the plane of the pressuremitigation device 1206. These steep inner side walls can form a channel that naturally positions the user 1202 over the chambers of the pressure-mitigation device 1206. Thus, inflation of the elevated side supports 1208 may actively force the user 1202 into the appropriate position for mitigating pressure by orienting the body in the correct location with respect to the chambers of the pressure-mitigation device 1206.

[00178] After the initial inflation cycle has been completed, the pressure of each elevated side support 1208 may be lessened to increase comfort and prevent excessive force against the lateral sides of the user 1202. Oftentimes, a healthcare professional will be present during the initial inflation cycle to ensure that the elevated side supports 1208 properly position the user 1202 over the pressure-mitigation device 1206, though that need not necessarily be the case (e.g., if the pressure-mitigation device 1206 is deployed in a home environment).

[00179] The controller 1212 can be configured to regulate the pressure of each chamber in the pressure-mitigation device 1206 (and the elevated side supports 1208 if included) via one or more flows of air generated by a pressure device 1214. One example of a pressure device is an air pump. These flow(s) of air can be guided from the controller 1212 to the pressure-mitigation device 1206 via tubing 1210. For example, the chambers may be controlled in a specific pattern to preserve blood flow and reduce pressure applied to the user 1202 when inflated (i.e., pressurized) and deflated (i.e., depressurized) in a coordinated fashion by the controller 1212. As shown in Figure 12, the tubing 1210 may be connected between the pressure-mitigation device 1206 and the controller 1212. Accordingly, the pressure-mitigation device 1206 may be fluidically coupled to a first end of tubing (e.g., single-channel tubing or multi-channel tubing), while the controller 1212 may be fluidically coupled to a second end of the tubing. While the pressure device 1214 is normally housed within the controller 1212, these components could be connected via tubing. Thus, the pressure device 1214 could be fluidically coupled to a first end of tubing (e.g., single-channel tubing or multi-channel tubing), while the controller 1212 may be fluidically coupled to a second end of the tubing. As mentioned above, the multi-channel tubing 1210 may not be necessary in some embodiments. For example, the controller 1212 can directly attach to the pressure-mitigation device 1206, thereby eliminating the need for tubing between the controller 1212 and pressure-mitigation device 1206.

[00180] Likewise, the controller 1212 can be configured to regulate the electromagnetic field emitted by the wireless power transmission system 1222 via one or more flows of electrical current from an external power source 1224. One example of an external power source is a wall outlet. These flow(s) of electrical current can be guided from the controller 1212 to the wireless power transmission system 1222 of the pressure-mitigation device 1206 via electrical tubing 1220.

[00181] As discussed above, some embodiments of the system 1200 include a communication module configured to facilitate wireless communication with nearby computing devices. For example, the controller 1212 may include a communication module able to wirelessly communicate with hospital equipment 1216 involved in treatment of the user 1202 or ancillary devices 1218 involved in monitoring the user 1202 or assisting operators of the pressure-mitigation system. Examples of the hospital equipment 1216 can include ECMO machines, mechanical ventilators, mobile workstations, monitors, and the like. In some embodiments, the hospital equipment 1216 can be a part of the ancillary electronic devices 1218 that extract electrical energy from the wireless power transmission system 1222. The ancillary electronic devices 1218 can be devices within a predetermined proximity of the pressure-mitigation device 1206 but are not necessary for treatment using the pressure-mitigation device 1206 (e.g., motion sensors, pulse oximeters, electrocardiographs, blood pressure monitors, drug infusion pumps, ventilators).

[00182] Additionally or alternatively, the controller 1212 may be able to pressurize the inflatable chambers of the pressure-mitigation device 1206 based on information obtained from the hospital equipment 1216. For instance, the controller 1212 may alter a programmed pattern for pressurizing the inflatable chambers based on the current status of the hospital equipment 1216, whether the hospital equipment 1216 indicates that there is a problem, etc. As an example, the controller 1212 may receive, via the communication module, input from a mechanical ventilator that a procedure (e.g., suctioning, spraying of medication, bronchoscopy) will be performed. In such a scenario, the controller 1212 may cause all inflatable chambers of the pressuremitigation device 1206 to be pressurized (i.e., inflated) or depressurized (i.e., deflated) so that the procedure is easier to perform. Similarly, the controller 1212 may be able to initiate the flow of electrical current to the wireless power transmission system 1222 based on information obtained from the ancillary electronic devices 1218. For example, the controller 1212 may be able to detect at least one ancillary electronic device 1218 (e.g., here, a vital sign monitoring device) is generally low on battery. Rather than directly plugging the ancillary electronic device 1218 into a power interface, the controller 1212 can direct electrical current to the wireless power transmission system 1222, and the wireless power transmission system 1222 can emit an electromagnetic field that the ancillary electronic device 1218 can extract electrical energy from and charge. Additionally, the controller 1212 can be configured to automatically detect and/or select the ancillary electronic devices 1218 to power, decreasing the amount of time operators must spend monitoring ancillary electronic device 1218 and increasing overall efficiency and quality of treatment. Thus, the controller 1212 may discontinue treatment in accordance with the programmed pattern and/or the controller 1212 can cease emission of the electromagnetic field by the wireless power transmission system 1222 in response to determining that it is not safe, appropriate, or desirable to continue.

[00183] Figure 13 is a flow diagram of a process 1300 for varying the pressure in the chambers of a pressure-mitigation device that is attached to or juxtaposed to a human body in accordance with embodiments of the present technology. By varying the pressure in the chambers, a controller can move the main point of pressure applied by the surface across the human body. For example, the main point of pressure applied by the support surface to the human body may be moved amongst multiple predetermined locations by sequentially varying the pressure in different predetermined subsets of chambers. Note that the human body could be in nearly any position, with minimal changes to the process 1300. Thus, the pressure-mitigation device may be arranged so that pressure is relieved on an anatomical region located along the anterior or posterior side of the human body. The controller can independently control or direct fluid flow or airflow into the pressure-mitigation device. Additionally, the same controller can direct electrical current flow into a wireless power transmission system of the pressuremitigation device, as described in more detail with reference to Figure 14.

[00184] Initially, a controller can determine that a pressure-mitigation device has been connected to the controller (step 1301 ). The controller may detect which type of pressure-mitigation device has been connected by monitoring the connection between a fluid interface (e.g., the fluid interfaces 708 of Figure 7B) and the pressure-mitigation device. Each type of pressure-mitigation device may include a different type of connector. For example, a pressure-mitigation device designed for deployment on elongated objects (e.g., pressure-mitigation devices 100, 200, 400 of Figures 1 A-2B and 4) may include a first arrangement of magnets in its connector, and a pressuremitigation apparatus designed for deployment on non-elongated objects (e.g., the pressure-mitigation device 300 of Figures 3) may include a second arrangement of magnets in its connector. The controller may determine which type of pressuremitigation apparatus has been connected based on which magnets have been detected within a specified proximity. As another example, the pressure-mitigation device designed for deployment on elongated objects may include a beacon capable of emitting a first electronic signature, while the pressure-mitigation device designed for deployment on non-elongated objects may include a beacon capable of emitting a second electronic signature. Examples of beacons include Bluetooth beacons, USB beacons, and infrared beacons. A beacon may be configured to communicate with the controller via a wired communication channel or a wireless communication channel.

[00185] The controller can then identify a pattern that is associated with the pressuremitigation device (step 1302). For example, the controller may examine a library of patterns corresponding to different pressure-mitigation devices to identify the appropriate pattern. The library of patterns may be stored in a local memory (e.g., the memory 804 of Figure 8) or a remote memory that is accessible to the controller across a network. The controller may modify an existing pattern based on the pressuremitigation device, the user, the ailment affecting the user, etc. For example, the controller may alter an existing pattern responsive to determining that the pattern includes instructions for more chambers than the pressure-mitigation device includes. As another example, the controller may alter an existing pattern responsive to determining that the weight of the user exceeds a predetermined threshold.

[00186] In some embodiments, the pattern is associated with a characteristic of the user in addition to, or instead of, the pressure-mitigation device. For example, the controller may examine a library of patterns corresponding to different ailments or different anatomical regions to identify the appropriate pattern. Thus, the library may include patterns associated with anatomical regions along the anterior side of the human body, patterns associated with anatomical regions along the posterior side of the human body, or patterns associated with different ailments (e.g., ulcers, strokes, etc.).

[00187] The controller can then cause the chambers of the pressure-mitigation apparatus to be inflated in accordance with the pattern (step 1303). As discussed above, the controller can cause the pressure on one or more anatomical regions of the human body to be varied by controllably inflating one or more chambers, deflating one or more chambers, or any combination thereof. For example, upon receiving input that is indicative of a request to initiate a deflation procedure for the pressure-mitigation apparatus (step 1304), the controller can cause deflation of one or more chambers of the pressure-mitigation apparatus (step 1305). Generally, all chambers of the pressuremitigation apparatus are deflated as part of the deflation procedure. If, for example, the pressure-mitigation apparatus is a pressure-mitigation device, the controller can cause deflation of its chambers and/or side supports. Steps 1304-1305 can be performed before, after, and/or simultaneously to operation of the wireless power transmission system, as described in more detail with reference to Figure 14.

[00188] Other steps may be performed in some embodiments. As an example, the controller may be configured to regulate inflation of the chambers based on a total duration of use of the pressure-mitigation device. For instance, the controller may increase or decrease the flow of air into the chambers (and, therefore, the pressure of those chambers) in a continual, periodic, or ad hoc manner to account for extended applications of pressure on the human body. In some embodiments, the controller determines the total duration of use based on a clock signal generated by a clock module housed in the controller. In other embodiments, the controller determines the total duration of use based on signal(s) generated by some other computing device. For instance, the controller may be able to infer how long the pressure-mitigation device has been used based on the presence of a signal generated by a computing device associated with the patient, such as a mobile phone or wearable electronic device. Said another way, the controller may infer the presence of the patient based on whether his/her computing device is located within a given proximity. For example, the controller may infer that the pressure-mitigation device has been in use so long as the computing device (1 ) is presently detectable (e.g., via a point-to-point wireless channel, such as Bluetooth or Wi-Fi P2P) and (2) has been detectable for at least a certain amount of time (e.g., more than three minutes, five minutes, etc.).

[00189] Those skilled in the art will recognize that the approaches to mitigating the pressure described herein may be useful in various contexts. Several examples are provided below; however, these examples should not be construed as limiting in any sense. Instead, these examples are provided to illustrate the usefulness of mitigating pressure in a few different scenarios.

[00190] Figure 14 is a flow diagram of a process 1400 for independently directing electrical current to a wireless power transmission system of a pressure-mitigation device that is attached to or juxtaposed to a human body in accordance with embodiments of the present technology. By directing electrical current to the wireless power transmission system, the controller can initiate emission of an electromagnetic field that one or more ancillary electronic devices can extract electrical energy from. For example, ancillary electronic devices can include vital signs monitors and/or displays that are not necessarily required for the operation of the pressure-mitigation device but can improve patient monitoring throughout treatment. The controller can also be configured to direct fluid flow or airflow into the chambers of the pressure-mitigation device to move the main point of pressure across the surface of the human body, as described above in more detail with reference to Figure 13.

[00191] Initially, a controller can determine that a pressure-mitigation device has been connected to the controller (step 1401 ). Similar to step 1301 discussed above in relation to Figure 13, the controller may detect which type of pressure-mitigation device has been connected by monitoring the connection between a power interface (e.g., the power interface 835 of Figure 8) and the pressure-mitigation device. Each type of pressure-mitigation device may include a different type of connector depending on the object the pressure-mitigation device is configured to be deployed on, the number of power interfaces on the pressure-mitigation device, the number of fluid interfaces on the pressure-mitigation device, and/or the like. In some embodiments, the type of pressuremitigation device is identified by a magnet arrangement on or at the one or more connectors (i.e., power and/or fluid interfaces). Additionally or alternatively, an electronic signature of the pressure-mitigation device (e.g., a beacon) can be used to identify the type of pressure-mitigation device.

[00192] The controller can then identify at least one ancillary electronic device within a predetermined proximity to the wireless power transmission system of the pressuremitigation device (step 1402). For example, the controller can be configured to detect electronic signatures of the ancillary electronic devices within three to five meters of the controller. Depending on the type of wireless power source included in the wireless power transmission system and/or the amount of electrical current available, the predetermined proximity can differ. The controller may be in wireless communication with one or more ancillary electronic devices near the patient. Similar to the pressuremitigation device, each ancillary electronic device can be associated with a beacon or electronic signature (e.g., Bluetooth beacons, USB beacons, and infrared beacons, etc.) that is detectable by the controller. The controller can identify one or more characteristics (also referred to as a “status”) of the at least ancillary electronic device, such as functions, battery percentage, approximate operation time available based on current battery percentage, last charging time, etc. The one or more characteristics can be used to prioritize charging of the ancillary electronic devices within the predetermined proximity.

[00193] Additionally or alternatively, the controller can notify an operator about the ancillary electronic devices within a predetermined proximity. For example, the controller can provide an operator of a status of the ancillary electronic devices within proximity via a display (e.g., the display 710 of Figures 7A-7C), and an operator can choose which ancillary electronic device(s) to provide electrical energy to. In some embodiments, the controller automatically chooses which ancillary electronic device(s) to provide electrical energy to depending on the status of the ancillary electronic devices and/or the available power. The one or more characteristics of the ancillary electronic devices can be stored in a local memory (e.g., the memory 804 of Figure 8) or a remote memory that is accessible to the controller such that the controller can use historical charging data and other information about the ancillary electronic device to identify a status and priority of the ancillary electronic devices.

[00194] The controller then receives an input of a request to initiate power transmission to the at least one ancillary electronic device (step 1403). In some embodiments, the input of a request comes from an operator selecting one or more of the ancillary electronic devices the controller has identified on the controller display. Additionally or alternatively, the controller can automatically request that power be transmitted to one or more ancillary electronic devices based on, for example, the devices being below a threshold amount of battery power.

[00195] Upon receiving input that is indicative of a request to initiate a power transmission to the at least one ancillary electronic device (step 1403), the controller can cause transport of electrical current to the wireless power transmission system (step 1404). For example, the controller can cause electrical current from an external source (e.g., AC current from a wall outlet) to be transferred to one or more electrical conduits electrically coupled to a wireless power source. In some embodiments, the electrical current can be modified (e.g., amplified, attenuated, etc.) before being transferred to the electrical conduits of the wireless power transmission system. Once the electrical current has traveled through the wireless power source, the wireless power source can generate an electromagnetic field that the at least one ancillary electronic device can extract electrical energy from (step 1405). In some embodiments, the at least one ancillary electronic device is compatible with the wireless power source. For example, the ancillary electronic device includes a wireless power receiver that resonates with the emitted electromagnetic field such that the electromagnetic field induces a current in the wireless power receiver that can be converted or rectified into a DC current to charge the ancillary electronic device. Generating a time-varying electromagnetic field is discussed in greater detail with reference to Figure 11 .

[00196] In some embodiments, the wireless power transmission system already has enough electrical current to emit a time-varying electromagnetic field and/or the electromagnetic field is already being emitted. Steps 1402 and 1403 can be performed intermittently to adjust the ancillary electronic devices extracting electrical energy and/or to select a new ancillary electronic device to extract electrical energy.

[00197] Those skilled in the art will recognize that the approaches to power management described herein may be useful in various contexts. Several examples are provided below and herein; however, these examples should not be construed as limiting in any sense. Instead, these examples are provided to illustrate the usefulness of mitigating pressure in a few different scenarios. Processing System

[00198] Figure 15 is a block diagram illustrating an example of a processing system in which at least some operations described herein can be implemented. For example, components of the processing system 1500 may be hosted on a controller (e.g., controller 1212 of Figure 12) responsible for controlling the flow of fluid to the pressuremitigation device (e.g., pressure-mitigation device 1206 of Figure 12) and the flow of electrical current to the wireless power transmission system (e.g., wireless power transmission system 1222 of Figure 12). As another example, components of the processing system 1500 may be hosted on a computing device that is communicatively coupled to the controller.

[00199] The processing system 1500 may include a processor 1502, main memory 1506, non-volatile memory 1510, network adapter 1512 (e.g., a network interface), video display 1518, input/output device 1520, control device 1522 (e.g., a keyboard, pointing device, or mechanical input such as a button), drive unit 1524 that includes a storage medium 1526, or signal generation device 1530 that are communicatively connected to a bus 1516. The bus 1516 is illustrated as an abstraction that represents one or more physical buses and/or point-to-point connections that are connected by appropriate bridges, adapters, or controllers. The bus 1516, therefore, can include a system bus, Peripheral Component Interconnect (PCI) bus, PCI-Express bus, HyperTransport bus, Industry Standard Architecture (ISA) bus, Small Computer System Interface (SCSI) bus, USB, Inter-Integrated Circuit (l²C) bus, or bus compliant with Institute of Electrical and Electronics Engineers (IEEE) Standard 1394.

[00200] The processing system 1500 may share a similar computer processor architecture as that of a computer server, router, desktop computer, tablet computer, mobile phone, video game console, wearable electronic device (e.g., a watch or fitness tracker), network-connected (“smart”) device (e.g., a television or home assistant device), an augmented or virtual reality system (e.g., a head-mounted display), or another computing device capable of executing a set of instructions (sequential or otherwise) that specify action(s) to be taken by the processing system 1500.

[00201] While the main memory 1506, non-volatile memory 1510, and storage medium 1526 are shown to be a single medium, the terms “storage medium” and “machine-readable medium” should be taken to include a single medium or multiple media that store one or more sets of instructions. The terms “storage medium” and “machine-readable medium” should also be taken to include any medium that is capable of storing, encoding, or carrying a set of instructions for execution by the processing system 1500.

[00202] In general, the routines executed to implement the embodiments of the present disclosure may be implemented as part of an operating system or a specific application, component, program, object, module, or sequence of instructions (collectively referred to as “computer programs”). The computer programs typically comprise one or more instructions (e.g., instructions 1504, 1508, 1528) set at various times in various memories and storage devices in a computing device. When read and executed by the processor 1502, the instructions cause the processing system 1500 to perform operations to execute various aspects of the present disclosure.

[00203] While embodiments have been described in the context of fully functioning computing devices, those skilled in the art will appreciate that the various embodiments are capable of being distributed as a program product in a variety of forms. The present disclosure applies regardless of the particular type of machine- or computer-readable medium used to actually cause the distribution. Further examples of machine- and computer-readable media include recordable-type media such as volatile and nonvolatile memory 1510, removable disks, hard disk drives, optical disks (e.g., Compact Disc Read-Only Memory (CD-ROMS) and Digital Versatile Disks (DVDs)), cloud-based storage, and transmission-type media such as digital and analog communication links.

[00204] The network adapter 1512 enables the processing system 1500 to mediate data in a network 1514 with an entity that is external to the processing system 1500 through any communication protocol supported by the processing system 1500 and the external entity. The network adapter 1512 can include a network adapter card, a wireless network interface card, a switch, a protocol converter, a gateway, a bridge, a hub, a receiver, a repeater, or a transceiver that includes an integrated circuit (e.g., enabling communication over Bluetooth or Wi-Fi). [00205] The techniques introduced here can be implemented using software, firmware, hardware, or a combination of such forms. For example, aspects of the present disclosure may be implemented using special-purpose hardwired (i.e., nonprogrammable) circuitry in the form of ASICs, programmable logic devices (PLDs), field- programmable gate arrays (FPGAs), and the like.
