Abstract

A recording unit includes one or more signal sensors and a recording controller. The recording controller is configured to execute a first recording instruction to record first data received from the one or more signal sensors. The first data is recorded according to first recording rules that specify a first value of a parameter. The recording controller is also configured to, in response to an irregularity detected in the first data, execute a second recording instruction to record second data received from the one or more signal sensors. The second data is recorded according to second recording rules that specify a second value of the parameter, where the second value differs from the first value.

Claims

1. A recording unit comprising:

one or more signal sensors; and

a recording controller, wherein the recording controller is configured to;

execute a first recording instruction to record first data received from the one or more signal sensors, wherein the first data is recorded according to first recording rules, wherein the first recording rules specify a first value of a parameter; and

in response to an irregularity detected in the first data, execute a second recording instruction to record second data received from the one or more signal sensors, wherein the second data is recorded according to second recording rules, wherein the second recording rules specify a second value of the parameter, wherein the second value differs from the first value.

2. The recording unit of claim 1, wherein the parameter is associated with a recording schedule.

3. The recording unit of claim 1, wherein the parameter is associated with recording sensitivity.

4. The recording unit of claim 1, wherein the parameter is associated with recording duration.

5. The recording unit of claim 1 wherein the parameter is associated with recording resolution.

6. The recording unit of claim 5, wherein the recording resolution associated with the second value of the parameter is greater than the recording resolution associated with the first value of the parameter.

7. A system comprising:

one or more signal sensors;

a recording unit operative to record first data from the one or more signal sensors according to a recording plan; and

a docking station including;

an analyzer configured to analyze the first data received from the recording unit and to produce an analysis based on the first data; and

a controller configured to adapt the recording plan to produce an adapted recording plan in response to detection of an irregularity in the first data, the irregularity detected via the analysis;

wherein the recording unit is further operative to record second data from the one or more signal sensors according to the adapted recording plan in response to the detection of the irregularity.

8. The system of claim 7, wherein the adapted recording plan specifies a schedule associated with the recording of the second data.

9. The system of claim 7, wherein the adapted recording plan specifies a sensitivity associated with the recording of the second data.

10. The system of claim 7, wherein the adapted recording plan specifies a duration associated with the recording of the second data.

11. The system of claim 7, wherein the adapted recording plan specifies a resolution associated with the recording of the second data.

12. The system of claim 7, wherein the irregularity is detected by comparing the first data to a predefined pattern.

13. The system of claim 12, wherein the first data is received by the recording unit from a first sensor and wherein the adapted recording plan specifies a second sensor from which the recording unit is to receive the second data.

14. The system of claim 7, wherein the irregularity is detected by an indication that an average value of the first data over a particular duration exceeds a first threshold value.

15. The system of claim 7, wherein the irregularity is detected by an indication that at least one value of the first data exceeds a second threshold value.

16. The system of claim 7, wherein the irregularity is detected by an indication that a time characteristic of the first data matches a particular time characteristic.

17. The system of claim 7, wherein the irregularity is detected by an indication that a frequency characteristic of the first data matches a particular frequency characteristic.

18. The system of claim 7, wherein the first data includes first information received from a first sensor during a first time period and second information received from a second sensor during a second time period, and wherein the analysis includes detecting the irregularity in the first data by:

recognizing a first abnormal pattern in the first information;

recognizing a second abnormal pattern in the second information; and

detecting a correlation between the first abnormal pattern and the second abnormal pattern.

20. The method of claim 18, wherein the second information is received from a second sensor that is specified in the adapted recording plan.

19. A method comprising:

recording first data according to a recording plan, wherein the first data is based on first information received from a first sensor of one or more sensors during a first time period; and

in response to detection of an irregularity in the first data;

specifying an adapted recording plan, wherein the adapted recording plan is based on the recording plan; and

recording second data in accordance with the adapted recording plan, wherein the second data is based on second information received from one of the one or more sensors during a second time period.
