Abstract

A detection device for detecting the manner in which a peripheral device is removed from an electronic device is proposed. The detection device can be on the peripheral device or the electronic device and detects whether the peripheral device was removed in a manner that indicates the removal was intentional or unintentional.

Claims

1. A detection system for detecting a manner in which a peripheral device is removed from an electronic device, the detection system comprising:

a detector configured to sense an action during removal of the peripheral device from the electronic device; and

an output interface configured to output a signal corresponding to the action sensed.

2. The detection system of claim 1, wherein the detector comprises a touch sensor that senses if a portion of the peripheral device is touched during removal of the peripheral device from the electronic device.

3. The detection system of claim 2, wherein the touch sensor is one of a capacitive pad, a mechanical switch, a force transducer and a piezoelectric pad.

4. The detection system of claim 1, wherein the detector is a proximity sensor that senses if an object comes within a pre-determined distance of the detector during removal of the peripheral device.

5. The detection system of claim 4, wherein the proximity sensor is one of an optical sensor, an infrared sensor and a capacitive sensor.

6. The detection system of claim 1, further comprising a processor configured to compare the action sensed to a pre-determined action and in response to the action matching the pre-determined action, to provide the electronic device with an instruction corresponding to the pre-determined action.

7. The detection system of claim 6, wherein the instruction is to deactivate a system of the electronic device.

8. The detection system of claim 6, wherein the instruction is to turn off an audio output.

9. The detection system of claim 1, wherein the output interface is a wireless transmitter.

10. The detection system of claim 1, wherein the output interface is further configured to output a deactivation signal to deactivate a system on the electronic device.

11. The detection system of claim 1, wherein the detector is located on the peripheral device.

12. The detection system of claim 1, wherein the detector is located on the electronic device.

13. A method of detecting a manner in which a peripheral device is removed from an electronic device, the method comprising:

sensing an action during removal of the peripheral device from the electronic device; and

outputting a signal corresponding to the action sensed.

14. The method of claim 13, wherein the sensing comprises sensing if a portion of the peripheral device is touched during removal of the peripheral device from the electronic device.

15. The method of claim 13, wherein the sensing comprises sensing if an object comes within a pre-determined distance of the detector during removal of the peripheral device.

16. A system comprising:

an electronic device;

a peripheral device connectable to the electronic device;

a detector configured to sense an action during removal of the peripheral device from the electronic device; and

an output interface configured to output a signal corresponding to the action sensed.

17. The system of claim 16, wherein the detector and the output interface are located on the peripheral device.

18. The system of claim 16, wherein the detector is located on a connector for connecting the peripheral device to the electronic device.

19. The system of claim 16, wherein the detector and the output interface are located on the electronic device.

20. The system of claim 16, further comprising a processor configured to compare the action sensed to a pre-determined action and in response to the action matching the pre-determined action, to provide the electronic device with an instruction corresponding to the pre-determined action.

21. The system of claim 16, wherein the detector is a touch sensor.

22. The system of claim 16, wherein the detector is a proximity sensor.
