[ technical field ] A method for producing a semiconductor device

The present invention relates to an information capturing device, and more particularly, to an information capturing device capable of wirelessly activating other corresponding devices within a range.

[ background of the invention ]

generally, the information capturing device is portable and can be used to capture media data such as video and audio. With the rise of public security awareness, the portable information capturing device can be used as a security auxiliary device due to the features of portability and real-time information capturing, and is widely applied in various fields. For example, police officers can wear the information capturing device to assist police work during work, and the media data recorded by the information capturing device can be used for proving and clearing responsibility in the future. In use, the user can start the portable information capturing device to capture the real-time information by operating the start switch on the information capturing device.

[ summary of the invention ]

However, in an emergency situation, the user often has no time to manually start capturing, or has missed the time point when capturing the image and/or sound of the critical situation at the start. Most police personnel wear only one information capturing device, and only can shoot at a single visual angle, so that it is difficult to provide comprehensive media data. Even if some police officers do not wear the information capturing device, they cannot record the police affairs. In addition, some information capturing devices have no networking function, so that the remote server cannot be notified in real time when an event occurs.

Accordingly, the present invention provides an information capturing device, which is suitable for wirelessly activating corresponding information capturing devices within a range when an event occurs, and does not need to wait for manual activation, so as to automatically record an environmental image and/or sound when the event occurs in real time.

In some embodiments, the present invention provides an information retrieving device, which can also notify a remote server through a peripheral device supporting telecommunication technology when an event occurs.

In one embodiment, an information retrieving apparatus includes: a near field communication module, a recording unit, a storage unit, and a control unit. The control unit is coupled with the near field communication module, the video recording unit and the storage unit. The near field communication module receives an event message including a destination information. The recording unit captures an environment data. The storage unit stores the first identification code. The control unit compares the first identification code with the destination information. Wherein, when the first identification code is matched with the destination information, the control unit starts the recording unit. When the first identification code does not accord with the destination information, the control unit broadcasts the event information through the near field communication module.

[ detailed description ] embodiments

Referring to fig. 1 and 2, the event detecting and recording system includes a status sensor 20, a plurality of information retrieving devices 30a-30f, a trigger box (trigger box) device 40, and a server 60.

In this case, the state sensor 20 can sense a predetermined operation of a target object and generate event information when the predetermined operation occurs in the target object. For example, taking the target object as the gun 10, the status sensor 20 can be disposed on the holster 12 and generate an event message when the user pulls the gun 10 to sense an event that the gun 10 leaves the holster 12. Herein, the state sensor 120 may include a metal sensing element, and detect whether the gun 10 is in a sensing range through the metal sensing element. In another example, the status sensor 20 can be disposed on a hand ornament such as a bracelet or ring, and can sense a user's gun-lifting action to generate an event message when the user lifts the gun 10. Herein, the state sensor 20 may include a posture sensing element, and senses whether the hand wearing the hand ornaments moves and a moving direction through the posture sensing element. In another example, the status sensor 20 may also detect the sound of the gun 10 when fired by sound sampling and generate an event message when the sound of the gun is detected.

In some embodiments, each of the information capturing devices 30a-30f may be normally in an off state, a sleep state, or not operating, and may be activated only when an event occurs, thereby reducing power consumption and prolonging the lifetime of the information capturing devices 30a-30 f. In some embodiments, the information capture device 30a-30e may be a portable camera device. In some embodiments, the information capturing device 30f may be a stationary camera, such as: a tachograph mounted on the vehicle 50.

In some embodiments, the information capturing devices 30a to 30f may not have networking function, i.e. no remote communication module (e.g. WIFI module, 3G module, 4G module, etc.), so as to reduce the power consumption and prolong the service time of the information capturing devices 30a to 30 f.

In some embodiments, referring to FIG. 3, one or more of the information extraction devices 30a-30c, 30e-30f do not have networking capabilities, while others of the information extraction devices 30a-30f have networking capabilities 30 d.

Herein, the state sensor 20 further includes a near field communication module. When the event information is generated, the near field communication module broadcasts the event information. Here, the event information includes a destination information. For example, the nfc module may be, for example, a bluetooth Beacon (Beacon) module, and the event information may be a Beacon signal.

in some embodiments, referring to FIG. 4, each information extraction device 30 (i.e., any one of 30a-30 f) includes: a near field communication module 310, a recording unit 320, a storage unit 330, and a control unit 340. The control unit 340 is coupled to the nfc module 310, the recording unit 320 and the storage unit 330. Each information retrieving device 30 has an identification code, and the identification code is stored in the storage unit 330. In some embodiments, the information capturing devices 30a-30f have different identification codes.

For clarity of description, the identification code stored in the storage unit 330 is referred to as a first identification code hereinafter.

Referring to fig. 1 to 5, the information retrieving device 30 receives an event message by a nfc technology (step S110), i.e. receives the event message broadcast by the status sensor 20 through the nfc module 310. The control unit 340 reads the first identification code from the storage unit 330, and compares the first identification code with the destination information carried in the event information (step S120).

In one embodiment, when the first identification code matches the destination information, the control unit 340 activates the recording unit 320 (step S130), so that the recording unit 320 starts to capture an environment data to generate a corresponding media file, i.e. record images and/or sounds of the surrounding environment. When the first identification code does not match the destination information, the information retrieving device 30 broadcasts the event information by nfc (step S160), i.e. the control unit 340 directly sends the received event information in a broadcast form through the nfc module 310.

In some embodiments, the destination information in the event message may specify a unique identifier. For example, it is assumed that the first identifier stored by the information extraction device 30a is "05", the first identifier stored by the information extraction device 30b is "06", and the destination information is designated as "05". The information extraction devices 30a, 30b are both within the signal range of the state sensor 20, while the information extraction devices 30c-30f are outside the signal range of the state sensor 20. Both of the information capturing devices 30a and 30b receive the event information broadcast by the status sensor 20. Also, the first identification code "" 05 "" of the information extraction device 30a matches the destination information "" 05 "" in the event information, so that the recording unit 320 of the information extraction device 30a is activated to start extracting the environment data. The first identifier "06" of the information retrieving device 30b does not match the destination information "05" in the event message, so that the nfc module 310 of the information retrieving device 30b forwards the event message in a broadcast manner. At this time, the information capturing device 30c in the signal range of the information capturing device 30b receives the event information broadcast by the information capturing device 30b, i.e., the event information is transmitted to the information capturing device 30c via the information capturing device 30 b. When the first identification code of the information retrieving device 30c does not match the destination information in the event information, the nfc module 310 of the information retrieving device 30c will forward the event information in a broadcast manner, so as to broadcast the event information to the information retrieving devices 30d and 30e in the signal range, and further forward the event information to the trigger box device 40.

here, the trigger box device 40 has a networking function, that is, a remote communication module (e.g., a WIFI module, a 3G module, a 4G module, etc.). When receiving the event information, the trigger box device 40 can generate a notification signal according to the received event information, and transmit the notification signal to a server 60 by using the telecommunication technology, i.e. connect to the network through the telecommunication module, and transmit the notification signal to the server 60 through the network. The notification signal may include event information and location data of the trigger box device 40. Also, the event information may further include source information. The source information represents the identification code of the status sensor 20 that generated the event information. Therefore, the server 60 can know the location of the event by the source information carried by the event information in the notification signal. In some embodiments, the trigger box assembly 40 may be mounted on a cart 50 and networked via the cart network of the cart 50.

In some embodiments, the destination information in the event information may specify a plurality of identification codes or specify all of them. For example, it is assumed that the first identifier stored by the information extraction device 30a is "05", the first identifier stored by the information extraction device 30b is "06", and the destination information is designated as "all". At this time, after the information capturing devices 30a and 30b receive the event information, the control units 340 of both determine that the first identification code matches the destination information in the event information, and thus activate the recording unit 320 to start capturing the environment data.

In another embodiment, the event information may further include a time stamp, and the time stamp represents the time when the status sensor 20 generates the event information. At this time, the storage unit 330 of each information capturing device 30 further stores a time threshold.

In one embodiment, referring to fig. 6, when the first identifier matches the destination information, the control unit 340 activates the recording unit 320 (step S130) to enable the recording unit 320 to start capturing an environment data to generate a corresponding media file, i.e. recording images and/or sounds of the surrounding environment. When the first identification code does not match the destination information, the control unit 340 of the information retrieving device 30 first calculates a time difference between the timestamp of the event information and the current time (step S150), and compares the time threshold with the calculated time difference (step S152). When the timestamp does not fall within the time threshold, the control unit 340 discards the received event information (step S154), i.e., does not perform the broadcasting step of the event information (step S160). When the timestamp falls within the time threshold, the control unit 340 broadcasts the event information by the nfc technology (step S160), that is, the control unit 340 directly sends the received event information in a broadcast form through the nfc module 310. For example, assume that the time threshold is 10 minutes. When the time difference between the generation time of the event information and the current time (i.e., the time difference between the time stamp and the current time) exceeds 10 minutes, the control unit 340 discards the received event information. On the contrary, the control unit 340 broadcasts the event information in the nfc technology when a time difference between the generation time of the event information and the current time (i.e., a time difference between the time stamp and the current time) is less than or equal to 10 minutes.

In another embodiment, the event information may further include a location data, and the location data represents the geographic location of the state sensor 20 when generating the event information. At this time, the storage unit 330 of each information capturing device 30 further stores a distance threshold.

Referring to fig. 7, when the first identifier matches the destination information, the control unit 340 activates the recording unit 320 (step S130), so that the recording unit 320 starts to capture an environment data to generate a corresponding media file, i.e. record images and/or sounds of the surrounding environment. When the first identification code does not match the destination information, the control unit 340 of the information capturing apparatus 30 first calculates a distance difference between the position data in the event information and the current position (step S150 '), and compares the distance threshold with the calculated distance difference (step S152'). When the distance difference does not fall within the distance threshold, the control unit 340 discards the received event information (step S154'), i.e., does not perform the step of broadcasting the event information (step S160 is not performed). When the distance difference falls within the distance threshold, the control unit 340 broadcasts the event information by the nfc technology (step S160), that is, the control unit 340 directly sends the received event information in a broadcast form through the nfc module 310.

In some embodiments, the storage unit 330 of each information capturing device 30 further stores a peripheral device lookup table. The peripheral device lookup table records the identification codes of other information capturing devices 30 located in the periphery of the information capturing device 30. For clarity, the identification code recorded by the peripheral device lookup table is referred to as the second identification code hereinafter.

Referring to fig. 8, when the first identifier matches the destination information, the control unit 340 activates the recording unit 320 (step S130), so that the recording unit 320 starts to capture an environment data to generate a corresponding media file, i.e. record images and/or sounds of the surrounding environment. When the first identifier does not match the destination information, the control unit 340 of the information retrieving device 30 searches the surrounding device lookup table with the destination information in the event information (step S140). When the one or more second identification codes of the comparison table of the peripheral devices are matched with the destination information, the information capturing device 30 broadcasts the received event information by the nfc technology (step S160), i.e. the control unit 340 directly sends the received event information again in a broadcast form through the nfc module 310. Otherwise, when the one or more second identification codes of the peripheral device lookup table do not match the destination information, the control unit 340 of the information capturing device 30 discards the received event information (step S142).

in another embodiment, the event information may further include a time stamp, and the time stamp represents the time when the status sensor 20 generates the event information. At this time, the storage unit 330 of each information capturing device 30 further stores a time threshold.

In an example, referring to fig. 9, when the one or more second identification codes of the peripheral device lookup table correspond to the destination information, the control unit 340 of the information capturing device 30 first calculates a time difference between the time stamp in the event information and the current time (step S150), and compares the time threshold with the calculated time difference (step S152). When the timestamp does not fall within the time threshold, the control unit 340 discards the received event information (step S154), i.e., does not perform the broadcasting step of the event information (step S160). When the timestamp falls within the time threshold, the control unit 340 broadcasts the event information by the nfc technology (step S160), that is, the control unit 340 directly sends the received event information in a broadcast form through the nfc module 310.

In another example, referring to fig. 10, when the first identification code does not match the destination information, the control unit 340 of the information capturing device 30 calculates a time difference between the timestamp of the event information and the current time (step S150), and compares the time threshold with the calculated time difference (step S152). When the timestamp does not fall within the time threshold, the control unit 340 discards the received event information (step S154), i.e., does not perform the broadcasting step of the event information (step S160). When the timestamp falls within the time threshold, the control unit 340 further searches the peripheral device lookup table according to the destination information in the event message (step S140). When the one or more second identification codes of the comparison table of the peripheral devices are matched with the destination information, the information capturing device 30 broadcasts the event information by the nfc technology (step S160), that is, the control unit 340 directly sends the received event information in a broadcast form through the nfc module 310.

In another embodiment, the event information may further include a location data, and the location data represents the geographic location of the state sensor 20 when generating the event information. At this time, the storage unit 330 of each information capturing device 30 further stores a distance threshold.

in an example, referring to fig. 11, when the one or more second identification codes of the peripheral device lookup table correspond to the destination information, the control unit 340 of the information capturing device 30 calculates a distance difference between the position data in the event information and the current position (step S150 ') and compares the distance threshold with the calculated distance difference (step S152'). When the distance difference does not fall within the distance threshold, the control unit 340 discards the received event information (step S154'), i.e., does not perform the step of broadcasting the event information (step S160 is not performed). When the distance difference falls within the distance threshold, the information capturing device 30 broadcasts the event information by the nfc technology (step S160), i.e. the control unit 340 directly sends the received event information in a broadcast form through the nfc module 310. Otherwise, when the one or more second identification codes of the peripheral device lookup table do not match the destination information, the control unit 340 of the information capturing device 30 discards the received event information (step S142).

In another example, referring to fig. 12, when the first identification code does not match the destination information, the control unit 340 of the information capturing apparatus 30 calculates a distance difference between the position data in the event information and the current position (step S150 '), and compares the distance threshold with the calculated distance difference (step S152'). When the distance difference does not fall within the distance threshold, the control unit 340 discards the received event information (step S154'), i.e., does not perform the step of broadcasting the event information (step S160 is not performed). When the distance difference falls within the distance threshold, the control unit 340 further searches the peripheral device lookup table according to the destination information in the event information (step S140). When the one or more second identification codes of the comparison table of the peripheral devices are matched with the destination information, the information capturing device 30 broadcasts the event information by the nfc technology (step S160), that is, the control unit 340 directly sends the received event information in a broadcast form through the nfc module 310.

In some embodiments, referring to fig. 3, 13 and 14, when the information acquisition apparatus 30d of the received event information has the remote communication module 350, the control unit 340 generates a notification signal according to the event information (step S170), and transmits the notification signal to the server 60 by a remote communication technology through the remote communication module 350 (step S172). The notification signal may include event information and location data of the trigger box device 40. Also, the event information may further include source information. The source information represents the identification code of the status sensor 20 that generated the event information. Therefore, the server 60 can know the location of the event by the source information carried by the event information in the notification signal.

It should be noted that, although the steps are described in sequence, the sequence is not a limitation of the present invention, and persons skilled in the art should understand that the execution sequence of the partial steps can be performed simultaneously or exchanged in sequence where reasonable.

In some embodiments, the destination information carried by the event information generated by the state sensor 20 can be preset by an electronic device and stored in the storage unit of the state sensor 20. In other words, in the set state, the state sensor 20 can establish communication with the electronic device in a wired or wireless manner. Then, the electronic device generates a set value of the destination information and transmits it to the state sensor 20. The state sensor 20 is set to be brought into one or more designated identification codes as destination information at the time of generating event information based on the received setting value.

In one embodiment, the identification code of the information retrieving device 30 can be preset and stored in the storage unit 330 at the time of factory shipment. In another embodiment, the identification code of the information capturing device 30 can be preset by an electronic device and stored in the storage unit 330 of the information capturing device 30. In other words, in the set state, the information capturing device 30 can establish communication with the electronic device in a wired or wireless manner. Then, the electronic device generates a setting value of the identification code and transmits the setting value to the information capturing device 30.

In one embodiment, the threshold values (time threshold value or distance threshold value) may be preset and stored in the storage unit 330 at the time of factory shipment. In another embodiment, the aforementioned threshold values can also be preset by an electronic device and stored in the storage unit 330 of the information capturing device 30. In other words, in the set state, the information capturing device 30 can establish communication with the electronic device in a wired or wireless manner. Then, the electronic device generates a threshold value setting value and transmits the threshold value setting value to the information capturing device 30.

In one embodiment, the peripheral device lookup table may be assembled and loaded from the server 60 into each information retrieval device 30 for storage in the storage unit 330. In other words, each information acquisition device 30 can transmit its own position data and its own identification code to the server 60. The server 60 integrates the identification codes of the information capturing devices 30 within a predetermined range of the position data of each information capturing device 30 into a peripheral device comparison table based on the position data of each information capturing device 30, and returns the peripheral device comparison table to the corresponding information capturing device 30. For example, the information capturing device 30 with networking function will periodically establish communication with the server 60 via the network to update its own location data and receive the peripheral device mapping table recording the identification codes of other information capturing devices 30 within a predetermined range around the updated location data. The information capturing device 30 without networking function can transmit its own location data to the peripheral electronic devices with networking function by near field communication technology or wire, and further transmit to the server 60, and receive the returned comparison table of the peripheral devices.

In some embodiments, the storage unit may be implemented by one or more storage elements. The storage device may be, for example, a memory or a register, but is not limited thereto.

In some embodiments, the nfc module may be, for example, but not limited to, a bluetooth module.

In some embodiments, the aforementioned control unit may be implemented by one or more processing elements. Each processing element may be a microprocessor, microcontroller, digital signal processor, central processing unit, programmable logic controller, state machine, or any analog and/or digital device that manipulates signals based on operational instructions.

In some embodiments, the video recording unit can be implemented by a camera lens and an image processing unit. In one example, the image processing unit may be an image signal processing chip (ISP). In another example, the image processing unit and the control unit are implemented in the same chip.

In summary, the information capturing device of the present invention is suitable for wirelessly activating the corresponding information capturing device within the range when the event occurs, and does not need to wait for manual activation, so as to automatically record the environmental image and/or sound when the event occurs in real time. In some embodiments, the information capturing apparatus according to the present invention can also notify the remote server through the peripheral apparatus supporting telecommunication technology when an event occurs.
