Abstract

A method, performed by a tag device that is coupled to an electronic device, for initiating a function in the electronic device includes receiving a signal from an interrogator device. The method also includes determining from the signal to initiate a function in the electronic device, and signaling the electronic device to initiate the function.

Claims

1. A method, performed by a tag device that is coupled to an electronic device, for initiating a function in the electronic device, the method comprising:

receiving a signal from an interrogator device;

determining from the signal to initiate a function in the electronic device;

signaling the electronic device to initiate the function.

2. The method of claim 1, wherein signaling the electronic device to initiate the function comprises signaling the electronic device to at least one of power on or power off.

3. The method of claim 2, wherein signaling the electronic device to at least one of power on or power off comprises operating a switch in the tag device using the signal to at least one of power on the electronic device or power off the electronic device off.

4. The method of claim 1, wherein signaling the electronic device to initiate the function comprises signaling the electronic device to perform at least one of:

lock or unlock the electronic device;

modify content stored in the electronic device;

or

change a setting of the electronic device.

5. The method of claim 1, wherein determining from the signal to initiate the function comprises determining a level of the signal, wherein the function initiated in the electronic device depends on the level of the signal.

6. The method of claim 5, wherein determining from the signal to initiate the function comprises:

comparing the level of the signal to at least one threshold of a plurality of thresholds;

determining a highest threshold of the plurality of thresholds that was exceeded by the level of the signal;

determining to initiate a function associated with the highest threshold that was exceeded by the level of the signal.

7. The method of claim 5, wherein the level of the signal and the function initiated in the electronic device depend on proximity of the interrogator device to the tag device.

8. The method of claim 7, wherein the level of the signal comprises an amount of energy extracted from the signal by an energy harvesting rectifier in the tag device, wherein the amount of the extracted energy and the function initiated in the electronic device depend on the proximity of the interrogator device to the tag device.

9. The method of claim 5 further comprising providing an indication of the level of the signal as feedback to the interrogator device.

10. The method of claim 1 further comprising:

receiving a status indication from the electronic device;

providing the status indication to the interrogator device, wherein the signal from the interrogator device is received in response to providing the status indication.

11. The method of claim 1, wherein the signal is received using short range radio communication.

12. Tag device apparatus comprising:

a signal reception and processing element configured to receive a signal from an interrogator device and determine from the signal to initiate a function in an external electronic device; and

a control element coupled to the signal reception and processing element, wherein the control element is configured to signal the electronic device to initiate the function.

13. The tag device apparatus of claim 12, wherein the signal reception and processing element comprises an energy harvesting rectifier coupled to a processor and configured to:

extract energy from the signal; and

indicate to the control element when a level of the extracted energy is reached that is sufficient to signal the electronic device to initiate the function.

14. The tag device apparatus of claim 13, wherein the control element comprises a switch that is configured to signal the electronic device to initiate the function when the level of the extracted energy exceeds a threshold amount.

15. The tag device apparatus of claim 13 further comprising a memory element configured to store a feedback indication of whether the level of the extracted energy is sufficient to initiate the function in the electronic device.

16. The tag device apparatus of claim 12, wherein the control element is configured to initiate one of a plurality of different functions in the electronic device depending on a level of the signal from the interrogator device.

17. The tag device apparatus of claim 12 further comprising a memory element coupled to the signal reception and processing element, wherein the memory element is configured to store at least one of a status indication or control indication of whether the electronic device is at least one of powered on or off.

18. A method performed by an interrogator device for controlling a function in an electronic device, the method comprising:

determining, from a tag device coupled to an electronic device, a status for the electronic device;

sending a signal to the tag device to control a function in the electronic device based on the status for the electronic device.

19. The method of claim 18, wherein sending a signal to control the function in the electronic device comprises sending a signal to control in the electronic device at least one of:

powering on or off;

locking and unlocking;

modifying stored contents;

or

changing a device setting.

20. The method of claim 18 further comprising:

receiving feedback from the tag device of a level of the signal;

providing, in response to the feedback, a prompt to move the interrogator device closer to the tag device.
