Title: bodycam system
The various aspects and implementations relate to a body camera system for capturing audio-visual data and in particular to how to connect such camera system to another object.
Cameras that are wearable on bodies of people to record what happens around the person are for example worn by the police. Such bodycam systems are dedicated rugged systems that are generally relative expensive and suitable for only one use case. This is generally not an issue for use by the police, who may have to wear such cameras all time during their service.
It is preferred to provide a system for recording audio-visual data that can be worn by a person, for example on clothing worn by the person, that is convenient to handle, both in use and by wearing.
To this end, a first aspect provides a system for capturing of audio-visual data. The system comprising a first module and a second module. The first module comprises a capturing set comprising at least one sensor for capturing audio-visual data and generating an signal carrying the captured data and a first electrically conductive engagement unit comprising at least two first electrically conductive engagement elements.
The second module comprises a second electrically conductive engagement unit comprising at least two second electrically conductive engagement elements that are arranged to engage with the first electrically conductive engagement elements to have the first electrically conductive engagement unit with the second electrically conductive engagement unit and a connector arranged to provide the signal to a processing device separate from the system when the first electrically conductive engagement is engaged with the second electrically conductive engagement unit. In this system, a first set of the first electrically conductive engagement elements and the second electrically conductive engagement elements comprises an electrically conductive rods extending out of a first of the first module and the second module; and a second set of the first electrically conductive engagement elements and the second electrically conductive engagement elements comprises electrically conductive securing elements for engaging with the electrically conductive rods in a releasable locking fashion.
Such system allows for efficient and rugged attachment of the system to a garment or other article to be worn by a user. In particular, it allows for a wired connection between the system on one hand and a processing device like a mobile telephone on the other hand, which wired connection may be provided under clothing, rather than in front of it. This provides more protection to the wired connection.
In an implementation, the electrically conductive securing elements comprise biased clamps for exerting a friction force on the electrically conductive rods in a direction substantially parallel to the length of the rods to lockingly releasably engage with the rods. This implementation allows for a reliable mechanical connection of electrical conductors even in case of significant shocks.
In a further implementation, electrically conductive securing elements comprise latches to mechanically lock the electrically conductive rods in the receptacles. This implementation provides enhance mechanical security of the mechanical connection between modules, providing better reliability.
In again another implementation, the electrically conductive rods are provided with at least one of radial protrusions or radial indentations arranged to engage with the latches. Latches generally provide robust and secure locking.
In again a further implementation, the first module comprises a first sub-module comprising the capturing set, a first sub-unit engagement unit and a first electrical terminal unit electrically connected to the capturing set; and a second sub-module comprising the first electrically conductive engagement unit, a second sub-unit engagement unit arranged to engage with the first sub-unit engagement unit and a second electrical terminal unit arranged to be in conductive electrical contact with the first electrical terminal unit when the first sub-unit engagement unit is engaged with the second sub-unit engagement unit. This implementation allows the camera unit - in the first sub-module - to be taken off, if it would require particular protection or if recording of data is not allowed, for example in particular environments.
In yet another implementation, a first of the first sub-unit engagement unit and the second sub-unit engagement unit comprises a magnet and a second of the first sub-unit engagement unit and the second sub-unit engagement unit comprises an element comprising a ferro- magnetic material. Such implementation is relatively simple to manufacture and convenient to use.
In yet a further implementation, the electrically conductive securing elements are movable between a first position in which the electrically conductive securing elements engage with the electrically conductive rods in a releasable locking fashion and a second position in which the electrically conductive securing elements do not lockingly engage with the electrically conductive rods. This allows for convenient disengagement between the rods and the securing elements, which in turn allows for quick removal of the system from the garment.
In another implementation, the electrically conductive securing elements are connected to a securing body by means of an electrically isolating connection. This implementation allows for more efficient disengagement.
In a further implementation, the clamps are movable in a direction substantially perpendicular to the length of the electrically conductive rods. For such disengaging movement, less force may be required than for a direction in which a retention force may have to be overcome.
In again another implementation, the electrically conductive securing elements are rigidly connected to the securing body and the securing body is movable within the module in which it is provided. This implementation allows for more efficient disengagement.
In again a further implementation, the securing body is provided with an actuating member for engaging with the securing body to translate a movement of the actuating member to a sliding movement of the securing body. Such actuating member may be a lever arranged to provide leverage to the securing body, such that less force is to be applied to the actuating member than has to be applied to the securing body for the disengagement action.
In yet another implementation, the actuating member is arranged to rotatably move relative to the securing body. This allows for a convenient implementation and use.
In yet a further implementation, the electrically conductive rods are biased in an outward direction relative to the module in which the electrically conductive rods are provided. This allows for improved reliability of the mechanical and electrical connection.
In another implementation, the electrically conductive rods are biased by means of a spring. Such springs are relatively simple to use, providing an option to use readily available pogo pins to implement.
In a further implementation, the first module comprises a first guiding element for guiding a movement of the electrically conductive rods relative to the first module. This allows for quick and fast engagement of the modules, with less risk for bending of the rods.
In again another implementation, the second module comprises a second guiding element for guiding a movement of the electrically 5 conductive rods relative to the second module. This allows for quick and fast engagement of the modules, with less risk for bending of the rods.
In again a further implementation, the first module comprises a first housing for at least partially housing of components comprised by the first module and the second module comprises a second housing for at least partially housing components comprises by the second module. By providing a housing, sensitive electronic circuitry may be better protected agamst harsh environment, like rain and snow.
In yet another implementation, the first engaging means comprises four electrically rods and the second engaging means comprises four electrically conductive securing elements and wherein the four electrically conductive securing elements. Using for channels is convenient as it allows compatibility with the USB standard.
In yet a further implementation, a distal end of the electrically conductive rods are arranged to penetrate a layer of material, in particular a layer of woven material or knitted material. This implementation allows for convenient application of the system to a garment.
A second aspect provides a system for capturing of audio-visual data. The system comprises a first module and a second module.
The first module comprises an image sensor for capturing image data and generating an signal carrying the captured image data, an audio sensor for capturing audio data and generating an signal carrying the captured audio data, a user input sensor, a first processing unit and a first communication unit. The second module comprises: a second communication unit, arranged to be connected to the first communication unit via a wired connection, a second processing unit, a storage unit, and a third communication unit. In this system, the second processing unit is arranged to control the first processing unit, via the second communication unit and the first communication unit, to capture audio-visual data by means of at least one of the image sensor and the audio sensor, in response to receiving, by the second processing unit, via the first communication unit and the second communication unit, a user input signal generated by the user input unit; and the second processing unit is arranged to receive, via the first communication unit and the second communication unit, the captured audio-visual data and to perform at least one of storing the received audio- visual data in the storage unit, and sending the received audio-visual data to a remote server by means of the third communication unit.
Such system allows for manufacturing a relatively simple first module, while providing actual data processing and device control in the second module. This allows separation of the first module and the second module, such that the first module may be provided on an outer side of a person's garment and the second module inside, in a protected environment.
In an implementation, with the first module comprising a light source, the first processing unit is arranged to operate the light source to emit light if audio-visual data is captured by at least one of the image sensor and the audio sensor. And advantage of this implementation is that anyone close to the device and the wearer thereof is well warned of the fact that the camera 1s recording. If a person has privacy issues, he can move away from the camera in time.
In another implementation, the first processing unit operates the light source by an instruction received from the second processing unit, in response to the second processing unit receiving the user input signal. By providing full control by the second module, the first module may be provided in a more simple and less costly way.
In a further implementation, the second processing unit compares the user input signal to at set of at least a first pre-determined criterion and if the user input signal satisfies the first pre-determined criterion, the captured audio-visual data is stored in the storage unit. This allows operation of the camera only if the proper command is given. This, in turn, allows to reduce a risk of accidental operation of the system.
In again another implementation, the second processing unit compares the user input signal to at set of at least a second pre-determined criterion and if the user input signal satisfies the second pre-determined criterion, the captured audio-visual data is sent to the remote server. This allows for more diverse operation and, more in particular, for direct data capturing in case of, for example, emergency. Firstly, another person may be directly alarmed by data received by the remote server. Second, in particular in combination with an implementation where a light is turned on during operation of the image sensor, people who may have an intention of harming the wearer of the system, are warned that they are being recorded. For which reason they may flee.
In again a further implementation, wherein the light source is arranged to emit light in at least a first colour and a second colour, wherein the light source is operated to emit the first colour if the user input signal satisfies the first pre-determined criterion. This allows for warning users in different ways, depending on the operating mode of the image sensor.
In yet another implementation, the light source is arranged to emit light in at least a first colour and a second colour, wherein the light source is operated to emit the second colour if the user input signal satisfies the second pre-determined criterion. This allows for warning users in different ways, depending on the operating mode of the image sensor.
In yet a further implementation, the storage unit comprises computer executable data for programming the second processing unit to cause the second processing unit to run a procedure to monitor the second processing unit for the user input signal and to instruct the first processing unit to capture audio-visual data by means of at least one of the audio sensor and the image sensor. This allows for background operation of an application that controls the first module.
In another implementation, the user input sensor is embodied by the audio sensor and user input signal is generated by the audio sensor. The audio sensor may thus provide the function as capturing module for audio- visual data, as well as user in put unit. This means that the user input unit does not necessarily has to be implemented as a separate unit, within the system. This allows for less cost for manufacturing and it allows for more convenient use of the system.
In a further implementation, the user input sensor comprises a button and the user input signal is generated by the button. A button may be operated without making sound or by making very little sound.
Furthermore, such user input unit is reliable.
In again another implementation, the image sensor is provided with at least one lens, forming a camera. This allows for protection of the image sensor and allows for improved image quality.
In again a further implementation, the first module comprises a first housing for housing the image sensor, the audio sensor, the user input sensor, the first processing unit and the a fist communication unit, and a second housing for housing the second communication unit, the second processing unit, the storage unit and the third communication unit.
The various aspects and implementations thereof will now be discussed in further detail in conjunction with drawings. In the drawings:
Figure 1: shows a user with a camera system;
Figure 2: shows an exploded view of the camera system; and
Figure 3: shows a functional diagram of the camera system.
Figure 1 shows a person 102 wearing a camera system 100 on his shirt 196. The camera system 100 comprises a capturing module 110, an outer docking module 150 and an inner docking module 170. The outer docking module 150 is connected to the inner docking module 170 through the shirt 196. The capturing module 110 is connected to the outer docking module 150. To the inner connection module, a wired communication line 192 is provided for connecting the camera system 100 to a mobile telephone 350 as a computing device.
Figure 2 shows an exploded view of the camera system 100 with the wired communication line 192 connected to it. The capturing module 110 comprises a sensor housing 112,with a camera 114 provided therein as an image sensor, provided with a lens. The capturing module 110 further comprises a microphone 116 as an audio capturing device and a button 118 as a user input device. The button 118 may be provided with a light source.
In this implementation, a set 122 of spring loaded contact pins, popularly known as pogo pins, is provided at the back of the sensor housing 112 to facilitate electrical contact between the capturing module 110 and other devices to enable electronic communication with other devices.
The outer docking module 150 comprises an outer docking plate 154, a pin holder 156 and contact pins 158 or rods as part of a first electrically conductive engagement unit. The contact pins 158 are arranged to be mn electrically conductive contact with the set 122 of spring loaded contact pins at a proximal side of the contact pins 158, when the capturing module 110 is placed on - docked on - the outer docking module 150. The contact pins 158 may be provided with a sharp or pointed end at a distal end to allow for piercing of a fabric of the shirt 196.
To allow docking of the capturing module 110 on the outer docking module 150, a recess may be provided in the back of the capturing module 110 to accommodate the pin holder 156 to ensure each of the spring loaded contact pins 122 is in contact with one of the contact pins 158. In one example, this allows for the spring loaded contact pins 122 to bias the contact pins 122 out of the outer docking module 150.
To secure the capturing module 110 to the outer docking module 150 and prevent the capturing module 110 from falling off the outer docking module 150, securing means may be provided. The securing means may comprise at least one magnet, in particular a permanent magnet, and at least one element comprising a ferromagnetic material. The permanent magnet may be provided in a first of the capturing module 110 and the outer docking module 150 and the element comprising the ferromagnetic material may be provided in a second of the capturing module 110 and the outer docking module 150. In another example, the capturing module 110 and the outer docking module 150 are provided in one and the same housing.
To connect and preferably fixate the camera system 100 to the shirt 196, the contact pins 158 protrude through the back of the outer docking module 150, through the pin holder 156 and through the hole in the outer docking plate 154. The contact pins 122 protrude through the fabric of the shirt 196 and are, as indicated above, provided with a pointed distal end to enable piercing through a woven or knitted material, but also through a continuous layer of material, like neoprene.
The inner docking module 170 comprises an inner docking plate 174 and a back housing 172. The inner docking plate 174 and the back housing 172 form part of an inner docking housing. In the inner docking plate, a set 176 of holes are provided for receiving the contact pins 158.
Inside the inner docking module 170, clamping elements 182, as electrically conductive securing elements, are provided on a clamping carrier 184 as part of a second electrically conductive engagement unit. The clamping carrier 184 is in this example provided as predominantly comprising an electrically insulating material.
The clamping elements 182 are in this example electrically conductive and each of the clamping elements 182 is connected to a conductor in the wired communication line 192. At an opposite side of the wired communication line 192, a USB-C plug is provided, though other types of plugs may be envisaged as well.
The clamping elements 182 are arranged to receive the contact pins 158 such that each clamping element 182 receives a contact pin 158. As shown by Figure 2, the clamping elements 182 comprise a rounded front to enable insertion of the contact pins 158. Due to a bias provided by the clamping elements 182, more force is required to overcome a friction force and to pull the contact pins 158 from the clamping elements 182. In this way, the outer docking module 150 is firmly connected to the inner docking module 170.
In order to facilitate removal of the outer docking module 150 from the inner docking module 150 and thus in order to facilitate removal the contact pins 158 from the clamping elements, a lever 186 is provided.
The lever 186 is provided within the housing of the outer docking module via a lever hole 188 in the lever 186, left in the drawing.
By pulling - rotating - the lever 186 downward, the clamping carrier 184 is lifted upward such that the clamping part of the clamping elements 182 is removed from the contact pins 158. Hence, the clamping carrier is moved in a direction substantially perpendicular to the length of the contact pins. The lifting action of the clamping elements 182 allows free movement of the contact pins 156 relative to the inner docking module, thus allowing the outer docking module 150 to be removed from the inner docking module.
The clamping elements 182 described above and shown in Figure 1 allow relatively simple manufacturing of securing elements. In another implementation, a set of latches may be provided. Each latch is in such example arranged to secure a contact pin 158, for example by latching onto an unevenness in a contact pin 158, like a radial recess or a radial protrusion. Such recess or protrusion may be fully or partially circumferential to the contact pins 158. In other implementations, also other securing elements may be used, either conductive or not.
At the lower part of the inner docking module 170 and at the lower part of the inner docking plate 174, a housing support 180 is provided.
The housing support 180 extends downward from the inner docking module 170, at the side facing the outer docking module 150. The housing support 180 reduces and may prevent any risk of the camera system 100 tilting upward when worn.
Figure 3 shows a functional diagram of various components of the camera system 100 and the capturing module 110 in particular and the mobile telephone 350 operationally connected thereto. As discussed above, the capturing module 110 comprises the camera 114, the microphone 116, the switch and the light source 120. Above, light source 120 is discussed as being provided in conjunction with the switch 118, but in other implementations, the light source 180 may be provided separately.
The camera 114, the microphone 116, the switch 118 and the light source 120 are connected to a capturing processing unit 132. The capturing processing unit 132 may comprise one or more integrated circuits, arranged to process data captured by the camera 114 and by the microphone 116. In one example, the capturing processing unit 132 is arranged to provide a stream of compressed audio-visual data, based on the data captured by means of the camera 114 and the microphone 116. It is noted that such audio-visual data may comprise solely audio data, solely video data or both audio and video data.
The capturing processing unit 132 is also arranged to receive a signal from the switch 118. The capturing processing unit 132 is in this example arranged to determine how long the switch 118 is operated. The capturing processing unit 132 may be arranged to determine how often and/or how long the switch 118 is operated within a particular time interval.
In another implementation, this processing may be performed by means of a telephone processing unit 352, which is discussed below. The switch 118 may be operated by means of a pushbutton, a knob, a sliding button, other, or a combination of two or more thereof.
The capturing processing unit 132 may be further arranged to operate the light source 120. In Figure 3, the light source 120 is depicted as a light emitting diode. In some implementations, the light source 120 may be implemented by means of more than one light emitting diode, providing a light source for RGB operation, which is arranged to emit light in different colours. The colour or colours emitted may be controlled by the capturing processing unit 132.
The capturing processing unit 132 is connected to a capturing memory 134 to store data and retrieve processed data and data to be processed. The capturing memory may store data to program the capturing processing unit 132 to execute the various steps discussed above and below and variations thereof.
To the capturing processing unit 132, a first USB communication unit 136 is connected for communicating data processed by the capturing processing unit 132 to a second USB communication unit 356 comprised by the mobile telephone 350. The second USB communication unit 356 is connected to a telephone processing unit 352 to provide the data received from the capturing module 110 to the telephone processing unit 352.
The telephone processing unit 352 is connected to a telephone memory 354 to store data and retrieve processed data and data to be processed. The telephone memory may store data to program the telephone processing unit 352 to execute the various steps discussed above and below and variations thereof.
The mobile telephone 350 further comprises a telephone transceiver 358 arranged to communicate with a cellular network or another wireless communication network. To this end, the telephone transceiver 358 is connected to the telephone processing unit 352. The mobile telephone 350 also comprises a touch screen 362 that provides functionality of a telephone user input module and telephone user output module. The telephone processing unit 352 is arranged to receive instructions from a user by means of the touch screen 362.
Furthermore, the mobile telephone 350 is arranged to provide user feedback by providing an audible signal via a speaker comprised by the mobile telephone 350, by means of a vibration unit comprised by the mobile telephone 250 or by means of earphones or headphones connected to the mobile telephone 350 by means of a wired or wireless connection, for example via a Bluetooth connection.
In operation, a set of computer readable instructions - a computer application, also known as an 'app' - is executed on the telephone processing unit 352. Running of the application may be initiated by means of an instruction provided by means of the touch screen 362.
While running the instructions, the telephone processing unit 352 listens, via the second USB communication unit 356, for any data provided by the capturing module 110, via the first USB communication unit 136. In standby operation, the computer application uses only few resources, while being continuously active in listening during operation of different and other applications. Upon receiving data, the computer application executed further actions as programmed.
Upon receiving a user input signal that complies with a first criterion, the telephone processing unit 352 instructs at least one of the camera 114 and the microphone 116 to capture audio-visual data. This instruction is communicated to the capturing processing unit 132, via the second USB communication unit 356 and the first USB communication unit 136. The user input signal may be generated by at least one of the switch 118 or by the microphone 116.
In operation, a signal generated by the switch 118 may be converted to a data signal by the capturing processing unit 132, which may send the data signal to the telephone processing unit 352, via the first USB communication unit 136 and the second USB communication unit 356.
If the user input signal is generated by the switch, the capturing of audio-visual data may be started by means of a brief single push. In such case, the first criterion is a short signal. If generated by the microphone, the signal may be the word "record" or an equivalent thereof in another language. In one particular optional example, the word "record" is to be spoken while operating the switch in order for the telephone processing unit 352 to capture the voice command.
While capturing the audio-visual data, the telephone processing unit 352 may control the light source 120 to emit light. More in particular, the telephone processing unit 352 may control the light source 120 to emit light with a particular colour, like white, green or blue.
In this example, audio-visual data captured as discussed above 1s stored in the telephone memory 354. If the user input satisfies another criterion, a different procedure may be executed. If a user operates the switch 118 for a longer time, for example more than three seconds, or multiple time in an interval, for example five time in five seconds, the telephone processing unit 352 may execute a different procedure for capturing and processing of audio-visual data. This may also be the case if a particular voice command is received by the telephone processing unit 352, for example "emergency" or "help" - or any equivalent thereof in a different language.
If the telephone processing unit 352 determines that the user input signal satisfies the second criterion, the telephone processing unit 352 may instruct at least one of the camera 114 and the microphone 116 to record data. The captured data, processed by the capturing processing unit
132 may in this case be directly transmitted to a remote server and stored there for further assessment.
Such implementation is particularly useful in emergency situations. As an option, geolocation data, captured by means of a geolocation module 364, is periodically provided with the audio-visual data sent to the remote server. During emergency operation, the light source 120 may be operated to emit light of a particular colour, for example white, red or yellow.
The telephone processing unit 352 may be arranged to process the audio-visual data received further. In case instructed, the telephone processing unit may be arranged to detect objects in the audio-visual data, for example faces.
