DETAILED DESCRIPTION

[0033] To make those skilled in the art able to better understand the solutions in the present disclosure, the technical solutions in the embodiments of the present disclosure are clearly and completely described hereinafter with reference to the drawings in the embodiments of the present disclosure. It should be apparent that the described embodiments are merely some rather than all embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those having ordinary skills in the art without going through any creative work should fall within the scope of protection of the present disclosure.

[0034] The terms "first", "second", "third" and the like in the specification, claims and drawings of the present disclosure are used to distinguish different objects, and are not used to describe a specific sequence. Furthermore, those terms "including" and "provided with" and any variations thereof are intended to cover non-exclusive inclusion. For example, processes, methods, apparatuses, products, or devices including a series of steps or units are not limited to the listed steps or units, but optionally include steps or units not listed, or optionally include other steps or units inherent to these processes, methods, products, or devices.

[0035] The following embodiments include plumbing devices such as faucets, bathtubs, toilets, and showers. The term "plumbing fixture" refers to an apparatus that is connected to a plumbing system of a house, building or another structure. The term "bathroom fixture" may more specifically refer to individual types of plumbing fixtures found in the bathroom. The term "kitchen fixture" may more specifically refer to individual types of plumbing fixtures found in the bathroom. The term "sanitary devices" may refer to the appliances found in the bathroom including toilets, urinals, lavatories, and other devices.

[0036] By way of introduction, a microwave radar sensor emits electromagnetic wave signals and receives electromagnetic wave echo signals reflected by targets. Millimeter wave radar sensor with FMCW (Frequency Modulated Continuous Wave) technology is a high-precision radar ranging technology that generates an intermediate frequency signal with target distance and signal strength after mixing the microwave transmitted wave with the reflected wave of the target through a radio frequency (RF) circuit. The intermediate frequency signal is processed to obtain the distance, intensity, and speed of the targets. Based on these behavioral characteristics of targets, the sensor identifies users approaching a sanitary device, movements of the users, and/or the duration of urination and controls the amount of water flushed to achieve water saving. [0037] The microwave radar sensor is configured to detect the presence of one or more objects or motion of one or more objects. The microwave radar sensor may be included in a control device according to the following embodiments, which includes a millimeter wave sensor module, a microcontroller unit (MCU), a solenoid valve or other type of valve, and at least one power supply or power supply circuit. The microwave radar sensor may be in communication with another control device. As used herein, the term "controller" refers to the microcontroller internal to the microwave radar sensor as well as any external control device. [0038] In one example, millimeter wave control unit, the microwave operating frequency can be selected as either 24GHz or 60/77GHz, with no frequency restrictions. The millimeter wave sensor control device is anonymous from users behind the back wall of the urinal or lavatory ceramic. In other words, the millimeter wave sensor control device is not visible to a user standing in front of the urinal or lavatory.

[0039] The basic process of microwave ranging, and speed measurement is summarized according to the following. The transmission antenna (Tx chirp) of the millimeter wave sensor module transmits millimeter wave signal. The receiving antenna of the millimeter wave sensor module receives reflected waves (Rx chirp) when there is a user in the range. The emitted wave and reflected wave are mixed in the mixer to generate an intermediate frequency signal in the millimeter wave sensor. The MCU of the millimeter wave sensor performs fast Fourier transform (FFT) operation on the intermediate frequency signal to obtain the distance, intensity, and velocity information of the targets (e.g., users and urine steams). Based on the characteristics of radar signals, when a person approaches or leaves or when urination starts and ends may be identified.

[0040] FIG. 1A illustrates an example millimeter wave radar device 111. The millimeter wave radar device 111 may be pointed in a variety of directions and mounted on a variety of devices including bathroom appliances and kitchen appliances as descried herein. The millimeter wave radar device 111 may detect objects (e.g., humans) even through a component of the bathroom appliances and kitchen appliances. For example, an opaque component may cover or otherwise shield the millimeter wave radar device 111 from vision of a person.

[0041] The millimeter wave radar device 111 may be associated with a detection range. The detection range may depend on factors such as the electrical power rating, antenna size, or other electrical parameters. The detection range may depend on the orientation or other placement of the millimeter wave radar device 111. The millimeter wave radar device 111 may be rated with or otherwise include multiple detection ranges. As shown in FIG. 1A, the millimeter wave radar device 111 includes detection ranges LI, L2, and L3. LI corresponds to a detection range at distance or height H where the millimeter wave radar device 111 detects objects when the millimeter wave radar device 111 is in a standby more or sleep mode. L2 corresponds to a detection range at distance or height H where the millimeter wave radar device 111 detects objects that are stationary when the millimeter wave radar device 111 is in an active mode. L3 corresponds to a detection range at distance or height H where the millimeter wave radar device 111 detects objects that are moving or active when the millimeter wave radar device 111 is in an active mode. In each instance the detection ranges may be defined according to the detection of humans. Other detection ranges are possible for other objects.

[0042] FIG. IB illustrates an example block diagram for the millimeter wave radar device 111. The millimeter wave radar device 111 may include components mounted on and electrically connected through a printer circuit board. The millimeter wave radar device 111 may include a microcontroller 152, at least one transmitter 153, at least one receiver 155, an analog to digital converter (ADC) 157, and a digital signal processor 159. As illustrated in FIG. IB, a pattern of receivers 155 may be included. For example, the millimeter wave radar device 111 may include a receiver 155 at each of four corners of the printer circuit board. Additional, different or fewer components may be included. [0043] The microcontroller 152 generates and/or initiates pulses to be emitted from the at least one transmitter 153. The pulses may be tuned according to a particular application. The microcontroller 152 may select a frequency based on an input setting specified by the user or manufacturer. The selected frequency may depend on the desired range for the device or the materials of the device. When the device is a toilet, a frequency is selected suitable for the materials of the toilet and the expected range of the user for the toilet. When the device is a lavatory, a frequency is selected suitable for the materials of the lavatory and the expected range of the user for the lavatory. Other devices as described herein may be associated with other frequencies for the emitted pulses.

[0044] The emitted waves (e.g., pulses) include millimeter electromagnetic wave energy that reflects of an object such as the user. The return waves (e.g., pulses) includes a smaller amount of electromagnetic wave energy than the emitted waves. The return waves are received at the at least one receiver 155 after a propagation delay and at a reflection angle. The microcontroller 152 is configured to calculate one or more kinematic properties of the object based on the energy, time, and/or angle of the return pulse. The transmitter 153 and the receiver 155 may be combined into a single component (e.g., transceiver).

[0045] The ADC 157 is configured to receive the radio waves as analog signals and covert the analog signals to digital signals that are analyzed by the microcontroller 152. Optionally, the digital signal processor 159 may analyze the digital signals.

[0046] As noted above, the MCU of the millimeter wave sensor 111 performs fast Fourier transform (FFT) operation on the intermediate frequency signal to obtain the distance, intensity, and velocity information of the objects. Based on the characteristics of radar signals, when a person approaches or leaves may be identified. The emitted wave and reflected wave are mixed in the mixer to generate an intermediate frequency signal in the millimeter wave sensor.

[0047] Specifically, the intermediate frequency signal is an electrical signal having a frequency and an intensity (e.g., an amplitude). The frequency of the intermediate frequency signal ranges from several-hundred Hz to about 5KHz. The frequency of the intermediate frequency signal has a mathematical relationship with a distance between the sensor 111 and the object (e.g., users or urine steams). The frequency of the intermediate frequency signal also has a mathematical relationship with a velocity of the motion of the object based on the Principle of Doppler (e.g., the Doppler shift). The object in motion with respect to the sensor 111 results in a change in the frequency of the waves generated by the sensor 111. Thus, the start time and the end time of the urine may be determined based on the frequency of the intermediate frequency signal. The frequency of the intermediate frequency signal increases when the distance between the sensor 111 and the object increases. The frequency of the intermediate frequency signal increases when the velocity of the motion of the object.

[0048] The intensity of the intermediate frequency signal indicates a probability of the presence of the object. This is because, when the echo signal is reflected by the object, the echo signal contains energy having a value. The probability of the presence of the object increases when the intensity of intermediate frequency signal increases. [0049] When the intensity of intermediate frequency signal is smaller than a predetermined intensity, the controller may determine that the intermediate frequency signal is an invalid signal and thus will not perform an A/D sampling and an FFT operation on the intermediate frequency signal.

[0050] The frequency and the intensity (e.g., the amplitude) of the intermediate frequency signal may be determined by using the FFT operation. Specifically, the microcontroller of the millimeter wave sensor 111 performs the A/D sampling. The changes in the frequency and the amplitude of the intermediate frequency signal correspond to the change in the voltage of the intermediate frequency signal. Thus, the voltages of the intermediate frequency signal may be sampled. Then, the MCU of the millimeter wave sensor performs the FFT operation on the intermediate frequency signal (e.g., the sampled voltages of the intermediate frequency signal) to obtain the frequency and the intensity (e.g., the amplitude) of the intermediate frequency signal so as to obtain the distance, intensity, angle, and/or velocity information of the objects (e.g., users and urine steams).

[0051] FIG. 2 illustrates an example toilet 100 including millimeter wave radar devices 111. The toilet 100 includes a toilet seat or ring 101 and a lid or cover 105 as well as other components. The toilet 100 may include a base 118 (e.g., a pedestal, bowl, etc.) and a tank 119. The base 118 is configured to be attached to another object such as a drainpipe, floor, or another suitable object. The base 118 includes a bowl, a sump (e.g., a receptacle) disposed below the bowl, and a trapway fluidly connecting the bowl to a drainpipe or sewage line. The tank 119 may be supported by the base 118, such as an upper surface of a rim. The tank 119 may be integrally formed with the base 118 as a single unitary body. In other embodiments, the tank 119 may be formed separately from the base 118 and coupled (e.g., attached, secured, fastened, connected, etc.) to the base 118. The toilet 100 may further include a tank lid covering an opening and inner cavity in the tank 119. The toilet 100 may include a seat assembly including a seat 101 and a seat cover or lid 105 rotatably coupled to the base 118. A tankless toilet may also be used. Additional, different, or fewer components may be included.

[0052] The toilet 100 is coupled to one or more millimeter wave radar device 111. In each example location, the millimeter wave radar device 111 may be in a cavity of the vitreous body of the toilet 100. Alternatively, the millimeter wave radar device 111 may be in a housing that is attached or adhered to the vitreous body of the toilet 100. In some examples an insert may be inserted into the mold for the toilet 100 as the vitreous body is formed. The insert may form the cavity for the millimeter wave radar device 111. One example location for the millimeter wave radar device 111 is inside the tank 119. One example location for the millimeter wave radar device 111 is inside the base 118. One example location for the millimeter wave radar device 111 is under the lid 117 of the tank 119. One example location for the millimeter wave radar device 111 is outside of the toilet 100 but in proximity to the toilet 100. For example, the millimeter wave radar device 111 may be mounted on the wall or ceiling. The one or more microwave sensors may not be visible from a front of the toilet 100.

[0053] In some examples, the cavity for the millimeter wave radar device 111 also includes a battery. The battery provides electrical power to one or more microwave sensors. The battery may be charged wirelessly through the vitreous material. For example, an inductive charger may be placed next to the vitreous material to charge the battery. In another example, the toilet 100 may include a turbine that is turned by the water entering or leaving the tank 119. The turbine generates electrical power that is used to charge the battery or otherwise provided to the millimeter wave radar device 111.

[0054] The millimeter wave radar device 111 is configured to collect sensor data descriptive of a user in proximity to the toilet 100. The millimeter wave radar device 111 may detect when a user is in a distance range. As described above, the distance range may depend on the state of the millimeter wave radar device 111 and the motion of the user. The millimeter wave radar device 111 may detect gestures of the user. The millimeter wave radar device 111 may detect the position of the user such as standing versus sitting. The microcontroller configured to receive sensor data from the microwave sensors and generate a control signal response for the toilet in response to the sensor data from the microwave sensors.

[0055] The control signal may be configured to actuate a valve. The toilet 100 may include a valve configured to selectively provide water at the toilet. The valve may include a fill valve that provides water from a water supply to the tank 119. The valve may be a flush valve that provides water from the tank 119 to the bowl or base 120. The valve may provide water to a rim outlet for rinsing the bowl. The valve may provide water to a sump jet.

[0056] The control signal may be configured to open or close the seat 101 or lid 105. In this way, when the user approaches the toilet 100 the seat 101 and/or lid 105 is opened. Similarly, when the user walks away from the toilet 100 the seat 101 and/or lid 105 is closed.

[0057] In some examples, the controller may instruct the toilet 100 or otherwise cause the seat 101 and/or lid 105 to remain closed when small children or pets approach the seat. When the sensor data indicates a first body size or shape, the control signal causes the toilet seat 101 or lid 105 to open, and when the sensor data indicates a second body size or shape, the toilet seat 101 or lid 105 remains closed. Similarly, in some examples when the sensor data indicates a first body size or shape, the control signal causes the toilet seat 101 or lid 105 to remain open, and when the sensor data indicates a second body size or shape, the toilet seat 101 or lid 105 is closed.

[0058] The control signal may be configured to fill the tank 119 only when a user is present. For example, the tank 119 may be left empty until the sensor data indicates that a user has approached the toilet. In response to the sensor data, the controller instructs the flush valve to turn on, filling the tank 119.

[0059] The control signal may be configured to activate a treatment device in response to the sensor data. The treatment device may apply an additive to the water in the tank 119. The treatment device may apply an electric current to the water in the tank 119. The treatment device may provide ozone to the water. The treatment device may include an ultraviolet light. [0060] The control signal may be configured to activate a cleaning device in response to the sensor data. The cleaning device may provide cleaning solution or other agent to the interior of the bowl or the tank 119.

[0061] The controller may analyze the sensor data to determine the presence and amount of solid waste in the toilet 100 and adjust the amount of water, force, or other parameters of the flush to ensure sufficient removal. For example, the controller may identify solid waste in the bowl and select a first amount of water for a flush if solid waste is present and a second amount of water for a flush is solid waste is not present. The amount of flush water may be set by the duration that the flush valve is opened. [0062] FIG. 3 includes another toilet 110 in which the millimeter wave radar device 111 is included in a toilet seat assembly. The millimeter wave radar device 111 may be visible when the seat 101 is opened to provide access for battery replacement, maintenance, or other purposes. When the seat 101 is closed, the millimeter wave radar device 111 is not visible. FIG. 4 illustrates the seat 101 in the closed position and dotted lines for the millimeter wave radar device 111 that is concealed by the seat 101.

[0063] FIG. 4 also illustrates a flushometer valve 151 that may house the millimeter wave radar device 111. The flushometer valve 151 may also be operated based on the control signal generated in response to the sensor data. The millimeter wave radar device 111 may detect the user and cause the flushometer 151 to flush the toilet 110.

[0064] The controller may also change the mode of the flushometer valve 151 when no user is present. The flushometer valve 151 may be switched to standby or a power save mode when no user has been present for a time period (e.g., 30 seconds). In this way power is conserved. In the case of battery power, the battery lifetime is improved.

[0065] FIG. 5 illustrates an example bidet including a millimeter wave radar devices. FIG. 5 illustrates a toilet 170 including one or more of the features above. The toilet 170 includes a bidet 178 as part of a seat assembly 176. The seat assembly 176 may connect or include a seat 177 that rests on a rim 175 of the toilet 170. In some examples, the millimeter wave radar device 111 is housed inside the bidet 178 and in others in the toilet 170.

[0066] The bidet 178 includes a handle 180 for manual operation (movement) and/or a button 181 for manual inputs (power on/off, modes, settings, etc.). The bidet 178 includes a rear wand 171 (e.g., first wand) including an arm 173 and one or more openings 280. The bidet 178 includes a front wand 172 (e.g., second wand) including an arm 183 and one or more openings 280.

[0067] Either bidet wand may be configured to spray water toward the user. When the sensor data indicates body size, body shape, or body position, the controller may cause the control signal to operate the rear wand 171 or the front wand 172 in response.

[0068] The rear wand 171 or the front wand 172 may be operable at different angles. When the sensor data indicates a first body size or shape, the control signal causes the bidet wand to dispense water at a first angle, and when the sensor data indicates a second body size or shape, the control signal causes the bidet wand to dispense water at a second angle. When the sensor data indicates a first body shape or position, the control signal causes the rear bidet wand to dispense water at a first angle, and when the sensor data indicates a second body shape or position, the control signal causes the front bidet wand to dispense water at a second angle.

[0069] FIG. 6 is a urinal 20 including a bowl 24, an inner portion 22, an outer portion 21, and a water outlet 23. Additional, different or fewer components may be included.

[0070] The urinal 20 may be substantially formed as a vitreous body. An example manufacturing technique for vitreous bodies is described herein. The vitreous body may include a front portion (e.g., user-facing side), which is opposite to a rear portion (e.g., fixture facing side) in certain embodiments. The urinal 20 may include the water outlet on the front portion and above the bowl 24. The bowl 24, which may be referred to as a basin or reservoir, is defined by a bowl surface that forms part of the front portion of the urinal 20. [0071] The urinal 20 may also include a trapway connected to the bowl 24 and for fluidly coupling the bowl 24 to a sewer or drainpipe at an outlet port. An inner portion 22 of the urinal extends upwardly from the bowl 24. The urinal 20 further includes a first side portion 28 and a second side portion 29 located opposite the first side portion 28. According to the exemplary embodiment shown, the urinal 20 is symmetrical about an x-z plane extending through the middle of the urinal 10, such that the first side portion 28 is the mirror image of the second side portion 29. The urinal 10 further includes an upper portion and a rear portion. The urinal 10 is configured to be coupled to, for example, a wall of a building at the rear portion (i.e., the urinal 20 is configured as a wall-hung urinal). It should be appreciated, however, that the urinal 20 may be configured as a floor-mounted urinal, according to other exemplary embodiments. The bowl 24 may also include, or otherwise be coupled to, a sump that extends to the trapway.

[0072] One example technique for manufacturing or otherwise forming the urinal 20 may include a series of steps. In a first step, a mold having the basic shape and structure of the urinal 20 is filled with liquid clay slip. The mold is oriented such that the rear portion is located on the bottom of the mold with the front portion oriented in an upward direction above the rear portion. In a second step, the liquid clay slip may set up in the cast to form the various solid cast walls of the urinal 20. In a third step, some components of the mold are removed (e.g., funnels for directing liquid slip into the mold, pins, etc.) and the mold is tilted at an angle relative to horizontal, such that the remaining liquid slip drains. In a fourth step, the mold may be laid flat with a back piece of the mold removed, such that various forming operations can be performed on the urinal 20 (e.g., holes punched, radii formed, etc.). In a fifth step, the mold may be flipped back over to remove the other parts of the mold from the urinal 10. Additionally, the various parting lines and edges of the urinal 20 may be removed or smoothed. In a seventh step, the urinal 20 is dried for a period of time. In an eighth step, the urinal 20 may be sprayed with glaze and then baked in a kiln to form the urinal 20.

[0073] FIGS. 7 and 8 illustrate the control system for improvements according to the present disclosure. FIG. 7 is an example wall installation for a control system for the urinal 20 according to an embodiment of the present disclosure. The control system, or at least a portion thereof, is installed, mounted, or otherwise coupled to components within the wall 25. The urinal 20 may be mounted to the wall 25. In this way the urinal 20 may not include any components of the control system. In some examples, the sensor 30 is mounted to the wall.

[0074] The control system includes a power supply 31, a control unit 32, a main valve 33, and a sensor 30. Optionally, an input valve 34 may connect the main valve 33 to a water supply. Additional, different or fewer components may be included.

[0075] The sensor 30 may be a microwave radar sensor. The microwave radar sensor emits electromagnetic wave signals and receives electromagnetic wave echo signals reflected by targets. One example frequency for the emitted electromagnetic waves is 24 GHz (i.e., wavelength of approximately 12.5 millimeters). The microwave radar sensor is configured to detect the presence of one or more objects or motion of one or more objects. The microwave radar sensor emits microwaves that may travel through a variety of media including both air and solid objects. The vitreous body of the urinal 20 is a solid body through which microwaves of the microwave radar sensor can travel. The microwave radar sensor may be minimally affected by external factors such as temperature, humidity, noise, airflow, light, scale, and residue. The microwave radar sensor may be configured to distinguish between water and open space.

[0076] The microwave radar sensor may continuously send out microwave signals through one or more transmitters. The microwave signals reflect, or otherwise return, based on the objects in the vicinity or detection range of the microwave radar sensor. Through analysis of the return signals through one or more antenna or receivers, it can be determined the motion and/or position of the objects in the vicinity of the microwave radar sensor. The sensor 30 may generate sensor data in response to the return signals that indicate the timing of the received signals. Different objects have different reflection characteristics for electromagnetic waves. The response time of the detection of the electromagnetic waves by the sensor 30 may be low (e.g., less than 0.5 seconds). [0077] The microwave radar sensor may include a circuit board (e.g., printed circuit board) having a predetermined arrangement of the one or more transmitters and one or more receivers. The sensor 30 may compare the received signals and calculate, based on the predetermined arrangement of the one or more receivers whether objects in the detection range of the microwave radar sensor have moved.

[0078] The sensor 30 may be coupled to the fixture-facing side (e.g., front portion) of the vitreous body. One example, object in the detection range of the sensor 30 is a urine stream S, as shown in FIG. 7, that the user is depositing in the bowl 24 of the urinal 20. In other words, as the user urinates into the bowl 24, the sensor 30 detects the presence of the urine stream S or motion of the urine stream S. The detection range may extend horizontally to the extent of the bowl 24. The detection range may extend vertically to a predetermined height along the inner portion 22 of the urinal 20. The urine stream S may also reflect the electromagnetic waves in a single and uniform relative motion speed. The sensor 30 and/or the control unit 32 may identify the urine stream S based on this characteristic.

[0079] The control unit 32 is configured to receive sensor data from the sensor 30 and generate a command to provide water to the water outlet 23 in response to the sensor data from the sensor 30. Water from the water outlet 23 flushes or rinses the urinal 20. The sensor 30 or the control unit 32 may analyze the sensor data to determine the duration of the urine stream S. The control unit 32 may determine a timer period for the water outlet 23 to release water based on the duration of the water stream S. For example, for every 10 seconds of the duration of the urine stream S, the control unit 32 activates the water outlet 23 to release water for 1 second. Other ratios or proportions may be used.

[0080] In some examples, the control unit 32 may analyze the sensor data indicative of the reflected electromagnetic waves to identify one or more characteristics of the object. In this way, the control unit 32 may distinguish liquids from solids, water from urine, urine from the human body, or any other combination of the above.

[0081] The main valve 33 is configured to selectively provide the water to the water outlet 23 in response to the command from the control unit. The main valve 33 may include a solenoid, a diverter, or another type of gate configured to selectively connect a plumbing system to the water outlet 23.

[0082] The plumbing system may include one or more pipes or hoses to connect the main valve 33 to the water outlet 23 and the main valve 33 to a water supply through an input valve 34. The input valve 34 is one example of a supply valve configured to provide a safety shutoff to the main valve 33. Other types of valves are possible. As shown in FIG. 7, the plumbing system includes a first path 41 (e.g., first pipe or hose) to connect the water supply (e.g., utility line, line-pressure water, water tank, recycled water, grey water, or other source) to the input valve 34, a second path 42 (e.g., second pipe or hose) to connect the input valve 34 to the main valve 33, and a third path 43 (e.g., second pipe or hose) to connect the main valve 33 to the water outlet 23. A portion of the plumbing system, as designated by path 44 may be internal to the urinal 20.

[0083] The control system further includes an electrical system. For example, the power supply 31 is configured to provide power to the control unit and/or the sensor 30. The power supply 31 may be electrically coupled to AC power for example for the house or building in which the urinal 20 is installed. Example AC power includes 110 Volts / 60 Hertz and 220 Volts 150 Hertz. The power supply 31 may be electrically coupled to a DC power source such as one or more batteries.

[0084] The power supply 31 may include a first battery for the control unit 32. The power supply 31 may include a second battery for the sensor 30. A single battery may provide power to both the control unit 32 and the sensor 30.

[0085] FIG. 8 is an example internal installation for a control system for the urinal 20 according to another embodiment of the present disclosure. In the example of FIG. 3, the control system, or at least a portion thereof, is installed, mounted, or otherwise coupled to components within the urinal 20. The urinal 20 may be mounted to the wall 25 or be supported apart from the wall 25. The urinal 20 includes substantial portions of the control system including two or more of the power supply 31, the control unit 32, the main valve 33, and the sensor 30. Optionally, the input valve 34 may connect the main valve 33 to a water supply internally or externally to the urinal 20. The urinal 20 may include a cavity include the main valve 33, the control unit 32, the power supply 31, and the sensor 30. A cover may conceal a rear portion of the urinal 20 including the cavity. In this way, the urinal 20 may include only a power port or connection to provide power to the power supply 31 and/or a water port or connection to provide water to the input valve 34 or the main valve 33. In some examples, the power supply 31 includes one or more batteries. In this example, the urinal may include a water port or connection. Thus, all components of the control system may be internal and only the water port or connection is external to the urinal 20. Additional, different or fewer components may be included.

[0086] In some examples, the flushing function of the water outlet 23 of the urinal 20 may also be performed by an override switch. The override switch may be mounted on the urinal or adjacent to the urinal 20 (e.g., on the wall 25). The override switch may be triggered by a physical depress, infrared induction, capacitive touch, etc. The urinal 20 may be mounted on wall such that the urinal 20 and the sensor 30 are on the user-facing side of the wall and the drain 48 is behind the wall. The urinal 20 may be mounted a predetermined distance above the floor.

[0087] A sensor zone may be defined based on the wall and/or the floor. For example, the user may stand up to a set back distance (e.g., 70 centimeters) from the wall and trigger the sensor 30 as a first feature and/or a urine stream may trigger the sensor 30 as a second feature.

[0088] The urine stream detection may be operable in a defined fluid detection zone. The defined fluid detection zone may be set according to a field of view (FOV) of the sensor 30. The control unit 32 may identify urine stream is within the FOV to determine the urine stream drops in the urinal bowl according to the second feature. [0089] The control unit 32 may also perform urine stream velocity signal processing. From the sensor 30, the control unit 32 may continuously or semi- continuously (e.g., based on a sampling rate) collect urine stream speed signals with consistent directions and in the speed range or velocity range of the set threshold. In one example, the velocity range, or a vertical component of the velocity range, is centered at 1 to 2 meters per second. [0090] The control unit 32 may determine a first characteristic (e.g., value or flag) in response to the presence of the user. The control unit 32 may determine a second characteristic (e.g., value or flag) in response to the presence of a urine stream. The control unit 32 may determine a third characteristic (e.g., velocity measurement) in response to the time period that the urine stream is detected.

[0091] After meeting the first, second, and third characteristics, the control unit 32 starts a timer. For example, the timer may be started when the speed signal appears, and stopped when the speed signal disappears. The control unit 32 may calculate the duration of urination. Based on the characteristics of a target discrimination model, the millimeter wave sensor detects the user is within the set range and there is a certain amount of speed information of urination for a certain period of time. The control unit 32 turns on the main valve 33 for an amount of time calculated from the measured time duration of the urine stream to dispense the certain amount of water to flush the urine. [0092] FIG. 9 illustrates a bathroom setting 130 including multiple sanitary devices. The sanitary devices may include one or more toilets 420, one or more urinals 430, and one or more sinks or lavatories including faucets 440. A water tank 412 and an additive tank 410 connect through a plumbing system (pipes 414, 416, 424, 426). One or more of the sanitary devices may include a millimeter wave radar device 111. In addition, one or more millimeter wave radar devices may be included in walls of the bathroom setting 130. Additional, different or fewer components may be included.

[0093] The locations of the millimeter wave radar devices 111 may be a predetermined pattern selected in order to cover the bathroom setting 130. The predetermined pattern may be selected to have redundancy in case of one sensor failing. The predetermined pattern may be selected to cover the high traffic paths in the bathroom setting 130.

[0094] Any of the millimeter wave radar devices 111 may monitor motion or user presence at any of the sanitary devices. For example, a millimeter wave radar device 111 mounted within one of the toilets 420 may also detect activity near urinal 430 or near faucets 440. The controller is configured to identify of sanitary devices in response to the sensor data and send an instruction to the identified at least one of the sanitary devices. For example, the millimeter wave radar device 111 at the toilet 420 may detect a user approaching urinal 430, and the controller sends an instruction after a time delay to flush the urinal 430. In one example, detection of a millimeter wave radar device 111 at the urinal causes an action, such as flushing, at a toilet. In one example, detection of a millimeter wave radar device 111 at the urinal causes an action, such as turning on water, at a faucet.

[0095] The controller may identify the user based on the sensor data. The controller may identify a detected object has a human. The controller may identify the gender of the user.

[0096] The controller may receive sensor data from multiple millimeter wave radar devices 111 and generate the control signal in response to sensor data from multiple millimeter wave radar devices 111. For example, the user may be tracked in a trajectory toward the toilet, which results in raising the lid, treating the water, etc. The user may be tracked in a trajectory away from the toilet, which results in initiation of a cleaning cycle, flushing the toilet, and starting a faucet. Starting the faucet may also indicate to the user which faucet to use.

[0097] A single controller (central controller) may receive sensor data from all of the millimeter wave radar devices 111. The central controller may also generate control signals for any of the sanitary devices. In other examples, a single millimeter wave radar device 111 is used for the sensor data and multiple sanitary devices are controlled. For example, the controller may receive data descriptive of a user in in a bathroom and generate multiple control signals for multiple sanitary devices. The controller generates, a first control signal for a first sanitary device a second control signal for a second sanitary device.

[0098] The central controller may track the number of users that enter the bathroom setting 130 and/or the particular locations that each user visits in the bathroom setting 130. The central controller may determine how long (dwell time) the user's stay at the particular locations. The central controller may adjust restocking timing based on the user activity. For example, the central controller may generate an alert to replace toilet paper after a predetermined number of people have visited the corresponding stall. Similar techniques may be applied to other consumables such as soap and paper towels.

[0099] The central controller may adjust cleaning timing based on the user activity. For example, the central controller may generate an alert to clean an area after a predetermined number of people have visited. The central controller may directly dispatch cleaning personnel.

[00100] The central controller may adjust maintenance timing based on the user activity. For example, the central controller may generate an alert to inspect or replace certain hardware (e.g., toilet seat, flush valve) after a predetermined number of people have visited. The central controller may directly dispatch maintenance personnel.

[00101] FIG. 10 is a lavatory 50 according to another embodiment of the present disclosure. The lavatory 50 is a sink including a basin 52 mounted on a countertop 51. The lavatory 50 includes a faucet 53. Optionally, the lavatory 50 may include one or more manual controls such as a hot water knob 54, a cold water knob 55, and a drain actuator 56. Additional, different or fewer components may be included.

[00102] The lavatory 50 may include a vitreous body including a user-facing side opposite to a fixture-facing side. The vitreous body may include the basin 52 and the countertop 51. The user-facing side of the vitreous body is illustrated in FIG. 5. The faucet 53 is a water outlet coupled to the user-facing side of the vitreous body.

[00103] FIG. 11 is an example control system for the lavatory 50. FIG. 11 illustrates the fixture-facing side of the lavatory 50 including portions of the countertop 51 and the basin 52.

[00104] The control system of the embodiment also includes a power supply 31, a control unit 32, a main valve 33, and a sensor 30. Optionally, an input valve 34 may connect the main valve 33 to a water supply.

[00105] The sensor 30 may be a microwave radar sensor as described herein. In the embodiment, one example frequency for the emitted electromagnetic waves is 60 GHz (i.e., wavelength of approximately 5 millimeters). The sensor 30 may be coupled to the fixture-facing side of the vitreous body of the lavatory 50. For example, as shown in FIG. 6, the sensor 30 is coupled (e.g., adhesive or fastened) to the basin 52. The sensor 30 may also be coupled to the countertop 51, preferably the fixture-facing side of the countertop. Because the microwave radar sensor emits microwaves that penetrate and pass through the lavatory 50, the sensor 30 can be mounted behind the lavatory 50 without line of sight, and out of sight of a user on the user-facing side of the lavatory 50. [00106] The detection range of the sensor 30 may be calibrated based on the position of the faucet 53. The detection range may extend horizontally only to the extent of the faucet 53. The detection range may extend vertically to a predetermined range under the faucet 53. In other words, the sensor 30 may be programmed to detect objects only directly below the faucet 53. The detection range of the sensor 30 may be set according to at least one distance range and at least one angle range.

[00107] The microwave radar sensor may continuously send out microwave signals through one or more transmitters. The microwave signals reflect, or otherwise return, based on the objects in the vicinity or detection range of the microwave radar sensor. Through analysis of the return signals through one or more antenna or receivers, it can be determined the motion and/or position of the objects in the vicinity of the microwave radar sensor. The sensor 30 may generate sensor data in response to the return signals that indicate the timing of the received signals.

[00108] The microwave radar sensor may include a circuit board (e.g., printed circuit board) having a predetermined arrangement of the one or more transmitters and one or more receivers. The sensor 30 may compare the received signals and calculate, based on the predetermined arrangement of the one or more receivers whether objects in the detection range of the microwave radar sensor have moved.

[00109] The control unit 32 is configured to receive sensor data from the sensor 30 and generate a command to provide water to the water outlet 23 in response to the sensor data from the sensor 30. Water from the water outlet 23 may be used for washing hands or other objects, rinsing the basin 52, or performing other cleansing or sanity functions.

[00110] The sensor 30 or the control unit 32 may analyze the sensor data to determine whether the user's hand is present under the faucet 53. The control unit 32 may determine a timer period for the water outlet 23 to release water based on the presence of the user's hand. In some examples, other that propagation delay, there is no delay between the presence of the user's hand below the faucet 53 and dispensing water from the faucet 53.

[00111] The main valve 33 is configured to selectively provide the water to the water outlet 23 in response to the command from the control unit. The main valve 33 may include a solenoid, a diverter, or another type of gate configured to selectively connect a plumbing system to the water outlet 23.

[00112] The plumbing system may include one or more pipes or hoses to connect the main valve 33 to the water outlet 23 and the main valve 33 to a water supply through an input valve 34. The input valve 34 is one example of a supply valve configured to provide a safety shutoff to the main valve 33. Other types of valves are possible. As shown in FIG. 6, the plumbing system includes a first path 41 (e.g., first pipe or hose) to connect the water supply (e.g., utility line, line-pressure water, water tank, recycled water, grey water, or other source) to the input valve 34, a second path 42 (e.g., second pipe or hose) to connect the input valve 34 to the main valve 33, and a third path 43 (e.g., second pipe or hose) to connect the main valve 33 to the water outlet 23. A portion of the plumbing system, as designated by path 44 may be internal to the urinal 20.

[00113] The control system further includes an electrical system. For example, the power supply 31 is configured to provide power to the control unit and/or the sensor 30. The power supply 31 may be electrically coupled to AC power or DC power source.

[00114] FIG. 12 is another example lavatory including at least one millimeter wave radar device 111. The basin 62 may be undermounted on a cabinet below the countertop 51. A housing 161 may be independently mounted on the cabinet. The housing 161 may include at least one millimeter wave radar device 111, the controller, a power supply, and a valve. The controller may operate the valve to selectively provide water to the faucet 53 through a water line 166 that is coupled to the faucet 53 through a connector 165.

[00115] FIG. 13 illustrates a bathroom setting 40 including multiple millimeter wave radar sensors 111. Example locations for the millimeter wave radar device 111 in the bathroom setting 40 include a bathtub 16, a cabinet 12, and a mirror 1. A lavatory 15 including a faucet 8 may rest on a countertop 108 of the cabinet 12. Additional, different or fewer components may be included.

[00116] The locations of the millimeter wave radar device 111 in the bathroom setting 40 are hidden and not viewable to a user. In one example, the millimeter wave radar device 111 may be placed behind a door 321 of the cabinet and be accessible using a handle 75 to open the door 321.

[00117] FIG. 14 illustrates a shower system 70 including at least one millimeter wave radar sensor 111. The shower system 70 includes at least one sprayer 121 or water dispenser, a user input display 122, at least one millimeter wave radar device 111, and a controller. The controller may be implemented by one or more of the millimeter wave radar devices 111. Alternatively, the shower system 70 may include a standalone controller. Additional, different or fewer components may be included.

[00118] The millimeter wave radar device 111 may be in various locations in the shower system 70 including on a tile, behind a tile, in the wall, on the wall, in the ceiling, on the ceiling, inside a showerhead, a hand sprayer, a body sprayer, or other locations. The millimeter wave radar device 111 may be placed in locations outside of the shower system 70. The millimeter wave radar device 111 may be spaced apart from the interior of the shower. At least one opaque object may separate the shower and the sensor. Example opaque objects include the tiles, walls, and flooring.

[00119] The opaque object may be a multifunctional tile that carries data, water, or power in a network or pattern defined by the tiles. The multifunctional tile may include a pipe, fluidic channel, solenoid, electrical conductor, or other devices. The millimeter wave radar device 111 may be included within the multifunctional tile and receive power from the electrical network established by the pattern of multifunctional tiles. The microcontroller of the millimeter wave radar device 111 may operate the solenoid of the multifunctional tile in response to the sensor data received at the multifunctional tile. The multifunctional tile may include multiple millimeter wave radar devices 111. [00120] The multifunctional tiles may be arranged along a wall or in a floor in a grid pattern, such that the entire wall or floor is covered by the multifunctional tiles. The multifunctional tiles may be selectively opened and closed to create different patterns of water that travels through the water paths of the multifunctional tiles or different patterns of water dispensers that spray into the shower 70. Thus, each shower tile may be part of different patterns such that any shower tile forms a first pattern through a first subset of a plurality of shower tiles and a second pattern through a second subset of the plurality of shower tiles. The controller may select the pattern in response to the position of the user or gestures of the user. When the sensor data indicates a first position of a user, the first pattern is selected, and when the sensor data indicates a second position of the user, the second pattern is selected.

[00121] The controller may receive sensor data from the millimeter wave radar device 111 and, in response to the sensor data, generate instructions for at least one of the water dispensers. The water dispensers may include shower head, rain showers, faucets, body sprayers, or hand sprayers. Additional water features may be included. The sensor data may include the position of the user. The sensor data may describe a gesture (e.g., hand movement, foot movement) performed by the user.

[00122] In one example, the instructions for the water dispenser are selected to move one or more water dispensers. A drive mechanism may be connected to one or more water dispensers and be configured to change an angle or height of the one or more water dispensers in response to the instructions from the controller.

[00123] One example scenario for adjusting the position of a water dispenser is to follow the user. In other words, as the user moves around within the shower, the controller tracks the user and generates instructions for the drive mechanism to move the water dispensers to continue to spray toward the user. In one example, the water dispenser may be moved so that the center of the spray corresponds to the position of the user.

[00124] In one example, the sensor data describes a body outline and the instructions for the water dispensers in response to the sensor data corresponds to the body outline. Certain sprayers may be moved based on the body outline. In some alternatives, water dispensers or individual nozzles may be activated or deactivated based on the body outline.

[00125] In addition, or in the alternative, the sensor data may describe a height and/or width of the user. The controller may identify the user based on height and/or width. The controller may identify a type of user based on the height and/or weight. Different types of users include adults, children, males, females, or others.

[00126] The controller may identify a body part that should be kept dry and turn on or off the water dispensers in a sequence and pattern that keeps water away from the identified body part. For example, the user may select a mode that keeps the hair dry. The controller may avoid water dispensers that would spray water on the user's hair. Similarly, the control may identify a cast or bandage and avoid water dispensers that would spray water on the cast or bandage.

[00127] Any of the examples with different water dispensing being turned and off may be implement with electronic mixing valves. Each of the mixing valves is associated with and fluidly coupled to one or more water dispensers. In this technique, water dispensers may be turned on and off as the user moves in the shower 70.

[00128] In addition, each mixing valve may be associated with a different zone. For example, the shower may be divided into four quadrants where each quadrant is serviced by multiple water dispensers coupled to a single mixing valve. In one example, the mixing valves are independently controlled to different temperatures. Thus, the shower 70 may include a hot zone and a cold zone, which are defined by user gestures or user movements. For example, a first mixing valve corresponds to a warmer portion of the shower, and a second mixing valve corresponds to a colder portion of the shower. [00129] In one example, the instructions for the water dispenser are selected to change a flow rate or intensity (e.g., water usage) of one or more water dispensers. This may be implemented by a variable valve configured to adjust a flow rate of at least one of the water dispensers.

[00130] One example scenario for adjusting the flow rate of a water dispenser may be to conserve water. The water flow is decreased when the user is not present. For example, the user may turn on the water but not actually enter the shower. In this situation, the water flow may be reduced. In addition, the water flow may be reduced when the user steps out of the water spray. For example, if the user steps out of the water to apply shampoo, shave, or perform other activities, the water flow can be reduced without affecting the user experience.

[00131] One example scenario for adjusting the flow rate of a water dispenser may be based on the distance between the water dispenser and the user. For example, as the user places a body part (or any object) closer to the water dispenser, the flow rate is increased. As the user places a body part (or any object) farther away from the water dispenser, the flow rate is decreased.

[00132] In another embodiment, the millimeter wave radar device 111 may be utilized to track water usage. The millimeter wave radar device 111 may collect sensor data for detection or estimation the flow of water sprayed by the water dispenser. The controller is configured to calculate the flow rate based on how much water is moving through the detection zone of the millimeter wave radar device 111. The sensor data may also describe a velocity of the water. The control signal from the controller may turn off the water dispensers after a predetermined amount of water has been used. In other examples, the water usage may be sent to an external device.

[00133] The millimeter wave radar device 111 may be installed in a puck that is impermeable to water. The puck is placed in the shower and monitors the water usage. The water usage may be transmitted to a server or other device wirelessly.

[00134] FIG. 15 illustrates an example cabinet 90 including at least one millimeter wave radar sensor 111. The cabinet 90 may be formed of a shelving unit 298 and a door 292. The front of the door 292 may include a mirror surface or mirrored member. The cabinet 90 may include a housing 291 including at least one millimeter wave radar device 111. The cabinet 90 may include a camera 295. The mirror surface may be a smart mirror that is implemented as a screen or display 296 using images or video from the camera 295. In other words, the display 296 mimics a mirror by providing images on the screen in real time or near real time as the images are collected by the camera 295. Additional, different or fewer components may be included. [00135] The images collected by the camera 295 may include or depict a user that is positioned relative to the smart mirror. The display 296 configured to display images collected by the camera 295.

[00136] In addition to the camera 295, the millimeter wave radar device 111 also collects sensor data in front of the mirror member. The sensor data may be descriptive of the user in proximity to the mirrored member.

[00137] The controller is configured to receive sensor data from the microwave sensors and generate instructions for the camera or display in response to the sensor data from the microwave sensors.

[00138] In one example, the controller causes the images on the display to be modified in response to the sensor data. The controller may modify an image parameter for multiple pixels in the image. Example image parameters may include color, brightness, hue, or others. A portion of the image may be increased in size in order to simulate a zoom function. This may be implements by changing the image parameters of the pixels in the image.

[00139] The zoom may be implemented when the user places a body part closer to the mirror. The sensor data describes the user's position relative to the smart mirror. As the users leans closer to the mirror, the controller determines that more zoom is needed and zooms into the image. As the user moves away from the mirror, the controller determines that less zoom is needed and zooms out. In another example, gestures may be identified from the sensor data. A first gesture causes the controller to zoom into the image. A second gesture causes the controller to zoom out of the image.

[00140] The controller may adjust a mode of the mirror based on the sensor data. The mirror may operate in a standby mode and an active mode. When the user approaches the mirror, the instructions cause the camera 293 or display 296 to enter the active mode (a first mode) and/or when the user moves away from the smart mirror, the instructions cause the camera 293 or display 296 to enter the standby mode (a second mode). Other mode changes are possible. n [00141] The controller may adjust an auxiliary device of the mirror based on the sensor data. One auxiliary device is an anti-fogging device that helps prevent the mirror from fogging. The anti-fogging device may provide heat to the mirror.

[00142] The controller may adjust an image property of the display 296. In one example, when the user approaches the mirror, the instructions cause the display 296 to brighten the image.

[00143] The controller may present data on the display 296 in response to the sensor data. In one example, when the user approaches the mirror, data is displayed for the time, date, battery life, or weather.

[00144] The controller modifies the video stream collected by the camera 295 based on the sensor data from the one or more millimeter wave radar devices 111. The modification may include zooming in on a predetermined region of the user's body, adjusting an image characteristic of the video stream, or cropping a portion of the video. [00145] FIGS. 16 and 17 illustrate an example movable mirror assembly 200 including at least one millimeter wave radar sensor 111. The movable mirror assembly 200 may include a mirrored surface 210, a frame 220, a data overlay 230, a mount 240, and an arm 250, and a support 260. The support 260 rests on a horizontal surface in the example of FIG. 16. The support 260 is mounted to a vertical surface or wall in the example of FIG. 17. Additional, different or fewer components may be included.

[00146] A drive mechanism 270 is configured to position the mirror. The drive mechanism 270 may include one or more motors or one or more solenoids. The drive mechanism 270 may include a telescoping arm that brings the mirrored member 210 closer to the user or to the object detected in the sensor data. The drive mechanism 270 may include a first motor or solenoid for a first degree of freedom or axis of rotation and a second motor or solenoid for a second degree of freedom or axis of rotation.

[00147] The first motor or solenoid of the drive mechanism 270 may rotate the frame 220 with respect to the mount 240 such that the rotation of axis is horizontal as shown in FIG. 16. The second motor or solenoid of the drive mechanism 270 may picot the frame 220 around the axis of arm 250. [00148] The one or more millimeter wave radar devices 111 of the mirror assembly 200 is configured to collect sensor data descriptive of a user in proximity to the mirror assembly 200. The controller is configured to receive sensor data from the microwave sensors 111 and generate instructions for the mirrored assembly 200 in response to the sensor data from the microwave sensors.

[00149] The instructions from the controller may adjust a position of the mirrored member 210 by commanding the drive mechanism 270 to move the mirror member 210. The instructions may provide a first angle for the first axis of rotation and a second angle for the second angle of rotation.

[00150] The movement of the mirrored member 210 may change the zoom or magnification of the mirror assembly 200. In one example, the mirror assembly 200 includes two mirrored surfaces. One mirror surface has a low magnification, and the other mirror surface has a high magnification.

[00151] The mirrored member 210 may also provide image adjustments with one or more active filters. The active filters may change a light intensity, brightness, or color. In this way, the instructions form the controller may select a light intensity, brightness, or color in response to the sensor data.

[00152] The mirror assembly include a data overlay 230 with a screen or a projector that presents a string of computer generated images and/or alphanumeric characters on the mirrored surface 210. In some examples, information from the sensor data may be included in the data overlay 230. The data overlay 230 may include data indicative of vitals of the user, weather data, or time data.

[00153] FIG. 18 illustrates an example lighting assembly 500 including at least one millimeter wave radar sensor 111. One or more lights 501 may be connected to a motor or solenoid configured to change the angle of the lights 501. The lighting assembly 500 may be mounted to a ceiling or otherwise at a high vantage point in a room. The millimeter wave radar device 111 collects sensor data for a large portion or all of the room. The controller is configured to analyze the sensor data to track or continuously update the position of one or more users present in the room. The controller generates a control signal for the motor or solenoid to move the lights 501 to follow the positions of the users so that the user's receive the best lighting at all locations in the room. Other settings may be available where the lights are pointed away from the users or pointed at multiple users simultaneously. The controller may also identify the user or type of user based on the sensor data and generate a control signal to adjust one or more lighting parameters in response to the sensor data. Example lighting parameters may include brightness, color, or hue. Alternatively, the controller may apply a lighting schedule according to the identified users. Some users may select lighting only at night. The lighting schedule may specify a start time or end time.

[00154] The lighting assembly 500 of FIG. 18 may also implement a control system to detect slips and falls using multiple millimeter wave radar devices 111. The following control system to detect slips and falls may be implemented by any embodiment described herein, including a collaboration of the millimeter wave radar devices 111 in the bathroom settings of FIGS. 9 and 13.

[00155] The lighting assembly 500 of FIG. 18 may also implement a security system and send alerts when intruders are present. For example, the user may provide a setting that the home residents are leaving the residence and the security system should be activity. If the millimeter wave radar devices 111 detect motion during this time, an alert is sent to a mobile device or an external device for emergency services. Similarly, the lighting assembly 500 or any of the millimeter wave radar devices 111 may detect when nobody is present in the home. The controller may turn off one or more system in response to an absence of humans in the home. Systems that may be shut down include water, air conditions, furnaces, electric, lights, and individual appliances.

[00156] The millimeter wave radar devices 111 are configured to collect sensor data descriptive of a user. The controller is configured to receive sensor data from the microwave sensors and identify an abnormal position of the user. The abnormal position is a fall or a fallen user.

[00157] The controller may analyze the sensor data to determine when the motion of the user indicates a fall. In one example, a fall is detected when the user moving in the direction of gravity and/or accelerating near the rate of acceleration of gravity. Thus, the controller detects a fall based on the velocity and/or acceleration of the user. [00158] In one example, the controller may compare the sensor data of the user to a template indicative of an abnormal position or fall. A memory (e.g., memory 352) is configured to store at least one template for the abnormal position of the user. The controller is configured to access the template from memory and compare the sensor data to the at least one template.

[00159] The millimeter wave radar device 111 may be pointed at or placed adjacent to a floor. When the floor is in the sensor region the millimeter wave radar device 111 may include a two dimensional footprint near the floor. One example is shown in FIG. 13 with the millimeter wave radar devices 111 in the cabinet. When a person is standing in such a sensor region, only a small part of the person is in the two dimensional footprint (e.g., standing feet or legs). However, if a person falls in the sensor region, the person will be laying on the floor, and a large portion of the person's body will be in the two dimensional footprint.

[00160] Another example is the shower system of FIG. 14. Any of the millimeter wave radar devices 111 may detect an abnormal position of the user in the shower by tracking movement of the user or detection the user laying on the floor.

[00161] Another example is the bathtub 16 of FIG. 13. The millimeter wave radar device 111 of the bathtub 16 may be configured to detect falls inside or outside of the bathtub 16 according to the techniques described herein. When the fall or slip is inside the bathtub, the controller may send a control signal to a valve to open a drain in response to the abnormal position.

[00162] The controller may also send the control signal to an annunciator device. The annunciator device is configured to provide an alert to the user in response to the abnormal position of the user. The annunciator device may include a light, a speaker, or a display to communicate the alert. The controller may also send an alert to an external receiver. The external receiver may be connected to the controller through a network device that communicates over radio waves, wirelessly, a telephone connection or the internet to the external receiver. Medical help may be dispatched by the external receiver. [00163] The bathtub 16 of FIG. 13 may also include, or operate as, a vital sign monitoring device. Other examples of the vital sign monitoring device include the shower system 70 and mirror described herein. The vital sign monitoring device includes at least one millimeter wave radar device 111 and a controller.

[00164] The controller of the vital sign monitoring device is configured to receive sensor data from the microwave sensors and identify a vital sign condition of the user. The sensor data may describe movement of the user's skin. The sensor data may describe a change in volume of the user's body.

[00165] Through these observations, the controller may calculate or otherwise estimate pulse. The heartbeat of a human body causes slight variation in the skin that can be measured by the millimeter wave radar device 111.

[00166] Through these observations, the controller may calculate or otherwise estimate respiration. As the user breathes the diaphragm raises the user's chest, which can be measured by the millimeter wave radar device 111.

[00167] Through these observations, the controller may calculate or otherwise estimate blood oxygen level from the color of the skin. A first color may indicate a first blood oxygen level and a second color may indicate a second blood oxygen level.

[00168] The bathtub 16 may be an ice bath. The ice bath may provide very cold water by applying a chiller to the water supply before dispensing the water. The controller may operate the chiller in response to the sensor data of the millimeter wave radar device 111. When the vital sign condition passes a threshold, the chiller may be turned off.

[00169] The bathtub 16 may include a valve configured to open or close in response to the vital sign condition of the user. For example, the valve may open a drain of a bathtub 16 in response to the vital sign condition. In another example, the valve may be a mixing valve configured to adjust a water temperature in response to the vital sign condition. When the vital sign condition exceeds a particular opening threshold, the valve is opened. When the vital sign condition exceeds a particular closing threshold, the valve is closed. [00170] The vital sign monitoring device may also include communication hardware to sends alerts of the vital sign conditions to external devices. The communications hardware may include a radio (e.g., 802.11, Bluetooth, etc.). The communications hardware may be configured to communication over the internet or cable to transmit data indicative of the vital sign condition to an external device.

[00171] The vital sign monitoring device may also include a local indicator that presents information indicative of the vital sign condition to an external device. The local indicator may include a light, a display, or a speaker.

[00172] FIG. 19 illustrates an example kitchen setting 320 including at least one millimeter wave radar sensor 111 mounded within a cabinet and hidden from view of the user. Additional kitchen devices may include integrated millimeter wave radar devices 111. Possible kitchen devices include a kitchen faucet 221, a dishwasher 322, a garbage disposal 323, a refrigerator 324 including a water dispenser 216, a water heater 25a including an upstream line 25c and a downstream line 25b, and a water filter 26. Each of the intelligent kitchen devices may be connected to a water supply 27 and a drain 328. Each of the intelligent kitchen devices is configured to collect data indicative of a user using the millimeter wave radar device 111 and adjust one or more settings and/or initiate operations in response to the sensor data.

[00173] The garbage disposal 323 may include an internal millimeter wave radar devices 111 that is configured to detect contents in the garbage disposal 323. A controller may determine whether there are contents inside the garbage disposal 323 and turn on the garbage disposal in response. The controller may determine when there is a high volume of contents inside the garbage disposal 323 and place the garbage disposal 323 in a boost mode in response to the high volume of contents. The controller may identify when a solid object, a hand, or other human body part is near the garbage disposal 323 and turn the garbage disposal 323 off in response to the detection of the object or human body part.

[00174] The kitchen faucet 221 may include a at least one millimeter wave radar sensor 111 as described above. The at least one millimeter wave radar sensor 111 collects sensor data in the vicinity of the kitchen faucet 221. The sensor data describes objects that are placed near the kitchen faucet 221. The controller turns on and off a valve for water to the kitchen faucet 221 in response to the sensor data. The controller may also select a temperature of the water through operation of a mixing valve in response to the sensor data.

[00175] In one example, the flow of the kitchen faucet 221 is adjusted depending on what objects are placed near the kitchen faucet 221. A low flow may be provided when hands are placed at the kitchen faucet 221 for washing. A high flow may be provided when a dish (e.g., a pan with food particles) is placed at the kitchen faucet 221. [00176] In one example, the flow of the kitchen faucet 221 is started and stopped to fill a detected pot. For example, the controller may determine a size of the pot. The controller may operate the valve for a calculated amount of time to fill the detected pot. [00177] The dishwasher 322 may include an internal millimeter wave radar device 111 that is configured to detect contents of the dishwasher 322. In one example, the controller automatically turns on the dishwasher at the appropriate cycle based on the sensor data. In another example, the sensor data describes users in proximity to the dishwasher 322. The controller may be configured to pause a cycle of the dishwasher 322 when users are present in order to reduce noise.

[00178] The dishwasher 322 may include an internal millimeter wave radar devices 111 that is configured to detect a type of container that is placed at the water dispenser 216. The controller may operate a valve for the water dispenser 216. The controller may select a time of operation of the valve for the water dispenser 216 to fill the detected container.

[00179] Any of the kitchen devices may include an internal millimeter wave radar devices 111 that is configured to detect users in proximity to the kitchen setting. The water heater 25a may include a controller that turns off the water heater 25a when no users are present for a predetermined time period.

[00180] An irrigation system may include one or more sprinklers or water dispensers (e.g., sprinklers) that are controlled based on one or more millimeter wave radar devices 111. The millimeter wave radar devices 111 may be mounted outdoors to detect when humans, animals, or pets are present in the lawn. The controller may open or close a valve for the irrigation system based on the sensor data. The irrigation system may pause operation, or a zone of operation, when humans, animals, or pets are present. In another example, the millimeter wave radar devices 111 may detect a foreign or unexpected pet or other animal in the yard (e.g., urinating or defecating in the yard) and the controller activates the valve to spray the animal and scare it away.

[00181] FIG. 20 illustrates an example trash receptacle 600 (garbage can) including at least one millimeter wave radar sensor 111. The trash receptable 600 includes a movable lid 601 and a base 602. A pedal 603 may be physical couple to the lid 601 such that pressing the pedal 603 causes the lid 601 to pivot upward and open the trash receptacle 600. In addition, or in the alternative, a drive mechanism (e.g., motor, solenoid) may be mounted internally and configured to open the lid 601. Additional, different or fewer components may be included.

[00182] A controller may generate instructions for the drive mechanism to open the lid 601 in response to the sensor data of the millimeter wave radar device 111. Certain gestures may be identified by the controller to trigger opening the lid 601. Presence of a user near the trash receptacle 600 may trigger opening the lid 601.

[00183] FIG. 21 illustrate an example hand dryer 279 including at least one millimeter wave radar sensor 111 and one or more hand opening 273. Additional, different or fewer components may be included.

[00184] A controller may generate instructions for the hand dryer 279 to operate an air pump in response to sensor data from the millimeter wave radar device 111. The controller may identify a gesture in the sensor data. In other examples, presence of the user in proximity to the dryer 279 triggers operation of the air pump.

[00185] The controller may cause the hand dryer 279 to operate in different modes depending on the sensor data from the millimeter wave radar device 111. When a larger human or larger hands are detected, a high output mode is detected. When a smaller human or smaller hands are detected, a low output mode is detected. A gesture may also allow the user to choose between the low output mode and the high output mode. [00186] FIG. 22 illustrate an example ceiling fan 290 including at least one millimeter wave radar sensor 111. The ceiling fan 290 may include a blower 190, a duct 192, and a power supply 140. Additional, different or fewer components may be included.

[00187] The millimeter wave radar device 111 may detect activity in the room below. The controller may operate the ceiling fan 290 in response to sensor data from the millimeter wave radar device 111. In one example, the controller may identify when a toilet is in use and trigger the ceiling fan 290 to turn on in response. In one example, the controller may identify when a shower is in use and trigger the ceiling fan 290 to turn on in response.

[00188] The controller may cause the ceiling fan 290 to operate in different modes depending on the sensor data from the millimeter wave radar device 111. When shower usage is detected, the ceiling fan 290 may be placed in a water exhaust mode. When toilet usage is detected, the ceiling fan 290 may be placed in an odor removal mode.

[00189] FIG. 23 is an example block diagram for a controller 1000, which may be implemented by the control unit 32 of any of the embodiments described herein. The controller 1000 may include a processor 300, a memory 352, and a communication interface 353 for interfacing with devices or to the internet and/or other networks 346.

In addition to the communication interface 353, a sensor interface may be configured to receive data from the sensors described herein or data from any source. The controller 1000 may include an integrated indicator (e.g., display, LED, speaker, or other output devices). The components of the control system may communicate using bus 348. The control system may be connected to a workstation or another external device (e.g., control panel) and/or a database for receiving user inputs, system characteristics, durations and any of the thresholds described herein.

[00190] Optionally, the control system may include an input device 355 and/or a sensing circuit 356 in communication with any of the sensors such as sensor 30. The sensing circuit receives sensor measurements from sensors as described above. The input device 355 may alternatively include one or more user inputs such as buttons, touchscreen, a keyboard, a microphone or other mechanism for calibrated any of the system characteristics, durations and any of the thresholds described herein.

[00191] Optionally, the control system may include a drive unit 340 for receiving and reading non-transitory computer media 341 having instructions 342. Additional, different, or fewer components may be included. The processor 300 is configured to perform instructions 342 stored in memory 352 for executing the algorithms described herein.

[00192] FIG. 24 illustrates an example flow chart for the operation of the controller 1000 for the control system of the apparatus having a vitreous body according to any of the embodiments described herein. Additional, different or fewer acts may be included.

[00193] At act S101, the controller 1000 (e.g., processor 300) receives sensor data from a microwave radar sensor describing position or movement of a user in proximity to a sanitary device.

[00194] At act S103, the controller 1000 (e.g., processor 300) compares the sensor data to a threshold. The threshold may be a position threshold. For example, when the motion of the object falls within a target position range, the threshold is met. The target position range may be selected by the controller 1000 from within the limited range of action of the microwave radar sensor.

[00195] At act S105, the controller 1000 (e.g., processor 300) sends a command to the sanitary device in response to the comparison. The command may open or close a valve of the sanitary device. The command may activate or deactivate a mode of operation of the sanitary device. The command may power on or off a circuit or component of the sanitary device.

[00196] FIG. 25 is a urinal 20 according to a first embodiment of the present disclosure. The urinal 20 includes a bowl 24, an inner portion 22, an outer portion 21, and a water outlet 23. The urinal may include at least one indicator 41 or light installed on the inner portion 22 of the urinal 20. Additional, different or fewer components may be included. [00197] The urinal 20 may be substantially formed as a vitreous body. An example manufacturing technique for vitreous bodies is described herein. The vitreous body may include a front portion (e.g., user-facing side), which is opposite to a rear portion (e.g., fixture facing side) in certain embodiments. The urinal 20 may include the water outlet on the front portion and above the bowl 24. The bowl 24, which may be referred to as a basin or reservoir, is defined by a bowl surface that forms part of the front portion of the urinal 20.

[00198] The urinal 20 may also include a trapway connected to the bowl 24 and for fluidly coupling the bowl 24 to a sewer or drainpipe at an outlet port. An inner portion 22 of the urinal extends upwardly from the bowl 24. The urinal 20 further includes a first side portion 28 and a second side portion 29 located opposite the first side portion 28. According to the exemplary embodiment shown, the urinal 20 is symmetrical about an x-z plane extending through the middle of the urinal 10, such that the first side portion 28 is the mirror image of the second side portion 29. The urinal 10 further includes an upper portion and a rear portion. The urinal 10 is configured to be coupled to, for example, a wall of a building at the rear portion (i.e., the urinal 20 is configured as a wall-hung urinal). It should be appreciated, however, that the urinal 20 may be configured as a floor-mounted urinal, according to other exemplary embodiments. The bowl 24 may also include, or otherwise be coupled to, a sump that extends to the trapway.

[00199] One example technique for manufacturing or otherwise forming the urinal 20 may include a series of steps. In a first step, a mold having the basic shape and structure of the urinal 20 is filled with liquid clay slip. The mold is oriented such that the rear portion is located on the bottom of the mold with the front portion oriented in an upward direction above the rear portion. In a second step, the liquid clay slip may set up in the cast to form the various solid cast walls of the urinal 20. In a third step, some components of the mold are removed (e.g., funnels for directing liquid slip into the mold, pins, etc.) and the mold is tilted at an angle relative to horizontal, such that the remaining liquid slip drains. In a fourth step, the mold may be laid flat with a back piece of the mold removed, such that various forming operations can be performed on the urinal 20. Example operations may include holes punched, radii formed, or inserts placed in the mold. In one example, a hole is punched, or an insert is used to provide an installation hole or cavity for the indicator 41. In a fifth step, the mold may be flipped back over to remove the other parts of the mold from the urinal 10. Additionally, the various parting lines and edges of the urinal 20 may be removed or smoothed. In a seventh step, the urinal 12 is dried for a period of time. In an eighth step, the urinal 20 may be sprayed with glaze and then baked in a kiln to form the urinal 20.

[00200] FIGS. 26 and 27 illustrate the control system for improvements according to the present disclosure. FIG. 26 is an example wall installation for a control system for the urinal 20 according to a first embodiment of the present disclosure. The control system, or at least a portion thereof, is installed, mounted, or otherwise coupled to components within the wall 25. The urinal 20 may be mounted to the wall 25. In this way the urinal 20 may not include any components of the control system. In some examples, the sensor 30 is mounted to the urinal 20, and in other examples, the sensor is mounted to the wall 25. The control system includes a power supply 31, a control unit 32, and a sensor 30. Additional, different or fewer components may be included.

[00201] The sensor 30 may be a microwave radar sensor. The microwave radar sensor emits electromagnetic wave signals and receives electromagnetic wave echo signals reflected by objects. In the first embodiment, one example frequency for the emitted electromagnetic waves is 24 GHz (i.e., wavelength of approximately 12.5 millimeters). The microwave radar sensor is configured to detect the presence of one or more objects or motion of one or more objects. The microwave radar sensor emits microwaves that may travel through a variety of media including both air and solid objects. The vitreous body of the urinal 20 is a solid body through which microwaves of the microwave radar sensor can travel. The microwave radar sensor may be minimally affected by external factors such as temperature, humidity, noise, airflow, light, scale, and residue. The microwave radar sensor may be configured to distinguish between water and open space.

[00202] The microwave radar sensor may continuously send out microwave signals through one or more transmitters. The microwave signals reflect, or otherwise return, based on the objects in the vicinity or detection range of the microwave radar sensor. Through analysis of the return signals through one or more antenna or receivers, it can be determined the motion and/or position of the objects in the vicinity of the microwave radar sensor. The sensor 30 may generate sensor data in response to the return signals that indicate the timing of the received signals. Different objects have different reflection characteristics for electromagnetic waves. The response time of the detection of the electromagnetic waves by the sensor 30 may be low (e.g., less than 0.5 seconds).

[00203] The microwave radar sensor 30 may include a circuit board (e.g., printed circuit board) having a predetermined arrangement of the one or more transmitters and one or more receivers. The sensor 30 may compare the received signals and calculate, based on the predetermined arrangement of the one or more receivers whether objects in the detection range of the microwave radar sensor have moved.

[00204] As noted above, the MCU of the millimeter wave sensor 30 performs fast Fourier transform (FFT) operation on the intermediate frequency signal to obtain the distance, intensity, and velocity information of the objects (e.g., users and urine steams). Based on the characteristics of radar signals, when a person approaches or leaves or when urination starts and ends may be identified. The emitted wave and reflected wave are mixed in the mixer to generate an intermediate frequency signal in the millimeter wave sensor.

[00205] Specifically, the intermediate frequency signal is an electrical signal having a frequency and an intensity (e.g., an amplitude). The frequency of the intermediate frequency signal ranges from several-hundred Hz to about 5KHz. The frequency of the intermediate frequency signal has a mathematical relationship with a distance between the sensor 30 and the object (e.g., users or urine steams). The frequency of the intermediate frequency signal also has a mathematical relationship with a velocity of the motion of the object based on the Principle of Doppler (e.g., the Doppler shift). The object in motion with respect to the sensor 30 results in a change in the frequency of the waves generated by the sensor 30. Thus, the start time and the end time of the urine may be determined based on the frequency of the intermediate frequency signal. The frequency of the intermediate frequency signal increases when the distance between the sensor 30 and the object increases.

[00206] The intensity of the intermediate frequency signal indicates a probability of the presence of the object. This is because, when the echo signal is reflected by the object, the echo signal contains energy having a value. The probability of the presence of the object increases when the intensity of intermediate frequency signal increases. [00207] When the intensity of intermediate frequency signal is smaller than a predetermined intensity, the MCU will determine that the intermediate frequency signal is an invalid signal.

[00208] The frequency and the intensity (e.g., the amplitude) of the intermediate frequency signal may be determined by using the FFT operation. Specifically, the MCU of the millimeter wave sensor performs the A/D sampling. The changes in the frequency and the amplitude of the intermediate frequency signal correspond to the change in the voltage of the intermediate frequency signal. Thus, the voltages of the intermediate frequency signal may be sampled. Then, the MCU of the millimeter wave sensor performs the FFT operation on the intermediate frequency signal (e.g., the sampled voltages of the intermediate frequency signal) to obtain the frequency and the intensity (e.g., the amplitude) of the intermediate frequency signal so as to obtain the distance, intensity, angle, and/or velocity information of the objects (e.g., users and urine steams).

[00209] In an ideal state, during the time difference, a reflected wave is formed by the object reflecting the transmission wave and has substantially the same wave shape as the transmission wave. In this embodiment, the reflected wave is in a linear shape, and thus the MCU may perform the FFT operation more easily.

[00210] There is a frequency difference (i.e., the frequency of the intermediate frequency signal) between the transmission wave and the reflected wave.

[00211] The sensor 30 may be coupled to the fixture-facing side (e.g., front portion) of the vitreous body. One example, object in the detection range of the sensor 30 is a urine stream S, as shown in FIG. 26, that the user is depositing in the bowl 24 of the urinal 20. In other words, as the user urinates into the bowl 24, the sensor 30 detect the presence of the urine stream S or motion of the urine stream S. The detection range may extend horizontally to the extent of the bowl 24. The detection range may extend vertically to a predetermined height along the inner portion 22 of the urinal 20. The urine stream S may also reflect the electromagnetic waves in a single and uniform relative motion speed. The sensor 30 and/or the control unit 32 may identify the urine stream S based on this characteristic.

[00212] The indicator 41 may be integrated with the vitreous body. For example, the vitreous body may be formed with inserts for one or more indicators 41 to be placed later. The at least one indicator 41 may include a light emitting diode (LED). The at least one indicator 41 may include a waterproof display screen that is coupled to the urinal 20.

[00213] The control unit 32 is configured to receive sensor data from the sensor 30 and generate a command to illuminate the at least one indicator 41 in response to the sensor data. In one example, the control unit 32 illuminates the at least one indicator 41 when the urine stream S is detected.

[00214] FIG. 27 illustrates another indicator 51 that simulates movement along a track 52 or set path. The indicator 51 is illustrated as a bug or insect. The movement of the bug or insect is simulated by illuminating different portions of the indicator or different indicators at different positions in the urinal 20.

[00215] In one example, the control unit 32 analyzes the sensor data and determines when the urine stream is near a target designated by the indicator 51. The control unit 32 may compare the sensor data to a positional threshold defined by the current position of the indicator 51. When the sensor data indicates that the urine stream S is near the target, the control unit 32 illuminated another indicator to simulate that the bug has moved to a new position. In this way, the user may be encouraged to follow the track 52 with the urine stream S.

[00216] FIG. 28 illustrates another indicator 61 that simulates a game. The control unit 32 may perform the actions of a computer player. The indicator 61 includes multiple detection zones. As just one example, a tic-tac-toe board includes nine zones. [00217] The control unit 32 may analyze sensor data and determine when the urine stream S has intersected a detection zone. In some examples, the control unit 32 determines when the detection zone has been targeted for a predetermined duration of time. In response to a detected hit of the urine stream S, the control unit 32 may cause an indicator to illuminate and display an "X" or "O" for the game. The control unit 32 may immediately select another "X" or "O" placement. In this way, the user is encouraged to pay attention to the urine stream S and selected targets within the safe splash zone of the urinal 20.

[00218] Other game scenarios are possible. When the control unit commands a first indicator to illuminate when the urine stream is detected in a first detection zone and commands a second indicator to illuminate when the urine stream is detected in a second detection zone.

[00219] A valve is configured to selectively provide the water to the water outlet 23 in response to the command from the control unit. The main valve may include a solenoid, a diverter, or another type of gate configured to selectively connect a plumbing system to the water outlet 23.

[00220] The plumbing system may include one or more pipes or hoses to connect the main valve to the water outlet 23 and the main valve to a water supply through an input valve. Other types of valves are possible to connect the water supply (e.g., utility line, line-pressure water, water tank, recycled water, grey water, or other source).

[00221] The control system further includes an electrical system. For example, the power supply 31 is configured to provide power to the control unit and/or the sensor 30. The power supply 31 may be electrically coupled to AC power for example for the house or building in which the urinal 20 is installed. Example AC power includes 110 Volts / 60 Hertz and 220 Volts / 50 Hertz. The power supply 31 may be electrically coupled to a DC power source such as one or more batteries.

[00222] The power supply 31 may include a first battery for the control unit 32. The power supply 31 may include a second battery for the sensor 30. A single battery may provide power to both the control unit 32 and the sensor 30. [00223] The control system for the urinal 20 may be internal to the urinal 20. The control system, or at least a portion thereof, is installed, mounted, or otherwise coupled to components within the urinal 20. The urinal 20 may be mounted to the wall 25 or be supported apart from the wall 25.
