Abstract

Systems and methods for archiving a stream of sensor data, are disclosed. One method comprises: receiving a stream of sensor data from at least one corresponding sensor device; storing the sensor data to a corresponding capture buffer; receiving, from a trigger device, a request to archive a portion of the capture buffer; and responsive to the archive request, copying the requested portion of the capture buffer to an archive buffer. The sensor device has a coverage area, and the trigger device is located proximate to the sensor coverage area. A user explicitly originates the archive request through the trigger device.

Claims

1. A method of archiving a stream of sensor data, the method comprising the steps of:

receiving a stream of sensor data from at least one corresponding sensor device, the sensor device having a coverage area;

storing the sensor data to a corresponding capture buffer;

receiving, from a trigger device that is proximate to the sensor coverage area, a request to archive a portion of the capture buffer, wherein a user explicitly originates the archive request; and

responsive to the archive request, copying the requested portion of the capture buffer to an archive buffer.

2. The method of claim 1, wherein the storing step further comprises:

storing the sensor data to the capture buffer in a circular manner such that newly recorded data persists for a buffer duration and is discarded after the buffer duration.

3. The method of claim 1, further comprising the steps of:

providing, to a client, an identifier of the archive buffer.

4. The method of claim 1, further comprising the steps of:

receiving, from a client, an archive buffer identifier; and

transmitting, to the client, the contents of the identified archive buffer.

5. The method of claim 1, further comprising the steps of:

determining an event interval associated with the archive request; and

identifying the requested portion based on the event interval.

6. The method of claim 1, further comprising the steps of:

configuring the trigger device so that a predetermined event interval is associated with the trigger device; and

responsive to the archive request received from the trigger device at a request time, identifying the requested portion based on the request time and the predetermined event interval.

7. The method of claim 1, wherein the at least one sensor device comprises a plurality of sensor devices, the method further comprising the steps of:

determining which of the at least one of the plurality of sensor devices is associated with the trigger device; and

responsive to the archive request received from the trigger device, identifying the requested portion based on the associated sensor device.

8. The method of claim 1, wherein the at least one sensor device comprises a plurality of sensor devices, the method further comprising the steps of:

configuring the trigger device so that the plurality of sensor devices is associated with the trigger device;

configuring the trigger device so that a predetermined event interval is associated with the trigger device;

responsive to the archive request received at a request time;

identifying the requested portion based on the request time and the predetermined event interval; and

copying the requested portion of each corresponding capture buffer to a corresponding archive buffer.

9. A system for archiving a stream of sensor data, comprising:

means for receiving a stream of sensor data from at least one corresponding sensor device, the sensor device having a coverage area;

means for capturing the sensor data to a corresponding buffer;

means for receiving, from a trigger device that is proximate to the sensor coverage area, a request to archive a portion of the capture buffer, wherein a user explicitly originates the archive request; and

means for copying the requested portion of the capture buffer to an archive buffer, in response to the archive request.

10. The system of claim 9, wherein the means for capturing further comprises:

means for storing the sensor data to the capture buffer in a circular manner such that newly recorded data persists for a buffer duration and is discarded after the buffer duration.

11. The system of claim 9, further comprising:

means for providing, to a client, an identifier of the archive buffer.

12. The system of claim 9, further comprising the steps of:

means for receiving, from a client, an archive buffer identifier; and

means for transmitting, to the client, the contents of the identified archive buffer.

13. The system of claim 9, further comprising:

means for determining an event interval associated with the archive request; and

means for identifying the requested portion based on the event interval.

14. The system of claim 9, further comprising:

means for configuring the trigger device so that a predetermined event interval is associated with the trigger device; and

means for identifying the requested portion, based on a request time at which the archive request received from the trigger device, and based on the predetermined event interval.

15. The system of claim 9, wherein the at least one sensor device comprises a plurality of sensor devices, the system further comprising:

means for determining which at least one of the plurality of sensor devices is associated with the trigger device; and

means for identifying the requested portion based on the associated sensor device.

16. The system of claim 9, wherein the at least one sensor device comprises a plurality of sensor devices, the system further comprising:

means for configuring the trigger device so that the plurality of sensor devices is associated with the trigger device;

means for configuring the trigger device so that a predetermined event interval is associated with the trigger device;

means for identifying, responsive to the archive request received at a request time, the requested portion based on the request time and the predetermined event interval; and

means for copying, responsive to the archive request received at a request time, the requested portion of each corresponding capture buffer to a corresponding archive buffer.

17. A method of archiving a stream of sensor data, the method comprising the steps of:

receiving a stream of sensor data from at least one corresponding sensor device, the sensor device having a coverage area;

storing the sensor data to a corresponding capture buffer;

receiving, from a trigger device that is proximate to the sensor coverage area, a request to archive a portion of the capture buffer, wherein the trigger device originates the request in response to an automatically recognized behavior occurring within the coverage area; and

responsive to the archive request, copying the requested portion of the capture buffer to an archive buffer.

18. The method of claim 17, wherein the trigger device comprises a gesture recognition device, and wherein the gesture recognition device originates the request in response to recognizing a gesture within the coverage area.

19. The method of claim 17, wherein the trigger device comprises a positional sensor, and wherein the trigger device originates the request in response to recognizing a specific body motion of a person within the coverage area.

20. The method of claim 17, wherein the storing step further comprises:

storing the sensor data to the capture buffer in a circular manner such that newly recorded data persists for a buffer duration and is discarded after the buffer duration.

21. The method of claim 17, further comprising the steps of:

22. The method of claim 17, further comprising the steps of:

receiving, from a client, an archive buffer identifier; and

transmitting, to the client, the contents of the identified archive buffer.
