Abstract

The described embodiments relate generally to methods, systems and devices for maintaining data integrity of storage media of a handheld electronic device, particularly when such device may be dropped, for example, i.e. subject to some unintended motion, which may cause the power supply to the storage media to be interrupted or terminated.

Claims

1. A method for maintaining data integrity of data stored on storage media of an electronic device, the device having:

(a) a detector configured to detect when the electronic device is moving; and

(b) a processor operatively coupled to the storage media and to the detector,

the method comprising;

(c) detecting when the electronic device is moving; and

(d) updating the data stored on the storage media responsive to the detection that the device is moving.

2. The method as claimed in claim 1, wherein the step of detecting when the electronic device is moving detects that the device is accelerating.

3. The method as claimed in claim 2, wherein the step of detecting detects that the device is accelerating at a rate above a threshold.

4. The method as claimed in claim 3, wherein the threshold is selected as a rate of acceleration that is indicative of unintended acceleration.

5. The method as claimed in claim 1, wherein the sensor is a freefall detector configured to detect when the electronic device is in freefall.

6. The method as claimed in claim 1, wherein the step of detecting when the electronic device is moving detects that the device is subject to a change in direction of movement.

7. The method as claimed in claim 6, wherein the step of detecting detects that the device is subject to a change in direction of movement at a rate of change above a threshold.

8. The method as claimed in claim 7, wherein the threshold is selected as a rate of change of direction of movement that is indicative of an unintended change of direction of movement.

9. The method as claimed in claim 6, wherein the detector comprising an inertial detector that detects a change of direction of movement of the electronic device irrespective of the effect of gravaity.

10. The method as claimed in claim 9, wherein the inertial sensor comprises a gyroscope.

11. The method as claimed in claim 1, wherein the data stored on the storage media comprises file allocation table data and wherein the step of updating comprises updating the file allocation table data.

12. The method as claimed in claim 1, wherein the electronic device further comprises a housing and a power supply port located within the housing and wherein the power supply port is configured to releasably receive a power supply module.

13. The method as claimed in claim 12, wherein the power supply module comprises a battery and wherein the housing comprises a compartment and wherein the power supply port is positioned within the compartment.

14. The method as claimed in claim 1, further comprising providing a sensory indicator to the user upon detection of the acceleration of the electronic device.

15. The method as claimed in claim 14, wherein the sensory indicator comprises an audible tone.

32. A computer readable medium storing computer readable instructions executable by a processor of a computing system to cause said system to implement the steps of the method of claim 1.

16. An electronic device, comprising:

(a) a housing;

(b) a detector operatively coupled to the housing and configured to detect when the electronic device is moving;

(c) a processor operatively coupled to the detector; and

(d) memory storage accessible to the processor and configured to store data and wherein the memory storage is further configured to store program code executable by the processor for executing a media memory preservation application, and wherein the media memory preservation application is configured to cause the processor to update the stored data.

17. The device as claimed in claim 16, wherein the processor is responsive to the detector, and wherein the processor is configured to execute the media memory preservation application upon the detector detecting that the device is moving.

18. The device as claimed in claim 16, wherein the detector is configured to generate motion signals upon detecting that the device is moving, and wherein the processor is configured to receive the motion signals.

19. The device as claimed in claim 18, wherein the processor is configured to execute the media memory preservation application upon receiving the motion signals.

20. The device as claimed in claim 16, further comprising a power supply port located within the housing and configured to releasably receive a power supply module.

21. The device as claimed in claim 20, wherein the power supply port is configured to release the power supply module.

22. The device as claimed in claim 20, further comprising a compartment within the housing, wherein the power supply port is positioned within the compartment.

23. The device as claimed in claim 22, further comprising a barrier movable from a closed position to an open position, wherein in the closed position access to the compartment is restricted.

24. The device as claimed in claim 23, wherein the barrier comprises a compartment cover.

25. The device as claimed in claim 16, wherein the memory storage comprises a storage media card.

26. The device as claimed in claim 25, wherein the memory storage comprises a flash memory card.

27. The device as claimed in claim 16, wherein the stored data comprises a file allocation table.

28. The device as claimed in claim 16, wherein the detector comprises a freefall detector for detecting when the device is in freefall.

29. The device as claimed in claim 16, wherein the detector comprises an accelerometer for detecting when the device is subject to an acceleration.

30. The device as claimed in claim 16, wherein the detector comprises an inertial detector for detecting a change in a direction of movement of said device.

31. The device as claimed in claim 30, wherein the inertial detector comprises a gyroscope.
