Abstract

A battery powered electronic device (112) is protected from being stolen in connection with battery charging. A method comprises establishing a connection with an electric charging device (102), entering a locked mode of operation, where the locked mode of operation comprises monitoring an existence of an unlock signal and monitoring an existence of the connection with the electric charging device, and performing a protective action in response to a non-existence of the signaling connection and a non-existence of the unlock signal.

Claims

1. A method in a battery powered electronic device for protecting the device from being stolen in connection with battery charging, the method comprising:

establishing a connection with an electric charging device,

entering a locked mode of operation, where the locked mode of operation comprises monitoring an existence of an unlock signal and monitoring an existence of the connection with the electric charging device, and

performing a protective action in response to a non-existence of the connection and a non-existence of the unlock signal.

2. The method of claim 1, wherein:

the establishing of the connection with the electric charging device comprises establishing a signaling connection, and

the monitoring of an existence of the connection with the electric charging device comprises monitoring an existence of the signaling connection.

3. The method of claim 1, wherein:

the establishing of the connection with the electric charging device comprises receiving electric charge from the electric charging device, and

the monitoring of an existence of the connection with the electric charging device comprises monitoring an existence of electric charge reception.

4. The method of claim 1, wherein the monitoring of an existence of an unlock signal comprises any of:

monitoring reception of an identification code;

or

monitoring reception of any of a voice detection signal, a face recognition signal and a biometric recognition signal.

5. The method of claim 1, wherein the performing of a protective action comprises providing any of an audible alarm indication and a visual alarm indication.

6. The method of claim 1, wherein the performing of a protective action comprises transmitting an alarm signal to an alarm signal receiving device.

7. The method of claim 1, wherein the performing of a protective action comprises at least partly disabling operation of the battery powered electronic device.

8. The method of claim 1, wherein the performing of a protective action comprises recording any of:

geographic location detected by the battery powered electronic device,

sound picked up by the battery powered electronic device, and

an image picked up by the battery powered electronic device.

9. A non-transitory computer-readable medium containing instructions executable by at least one processing unit, the non-transitory computer-readable medium storing instructions to:

establish a connection with an electric charging device,

enter a locked mode of operation, where the locked mode of operation comprises monitoring an existence of an unlock signal and monitoring an existence of the connection with the electric charging device, and

perform a protective action in response to a non-existence of the connection and a non-existence of the unlock signal.

10. A battery powered electronic device configured for protecting the battery powered electronic device from being stolen in connection with battery charging, comprising:

connection circuitry for establishing a connection with an electric charging device,

operation circuitry for entering a locked mode of operation, comprising monitoring circuitry for monitoring an existence of an unlock signal and monitoring circuitry for monitoring an existence of the connection with the electric charging device, and

protection circuitry for performing a protective action in response to a non-existence of the connection and a non-existence of the unlock signal.

11. The battery powered electronic device of claim 10, wherein:

the connection circuitry for establishing a connection with an electric charging device comprises circuitry for establishing a connection with a wireless electric charging device, and

the monitoring circuitry for monitoring an existence of the connection with the electric charging device comprises circuitry for monitoring an existence of a connection with the wireless electric charging device.

12. A method in an electric charging device for protecting a battery powered electronic device from being stolen in connection with battery charging, the method comprising:

establishing a connection with the battery powered electronic device,

monitoring an existence of an alarm signal transmitted by the battery powered electronic device, and

performing a protective action in response to the alarm signal.

13. The method of claim 12, wherein the performing of a protective action comprises providing any of an audible alarm indication and a visual alarm indication.

14. An electric charging device configured for protecting a battery powered electronic device from being stolen in connection with battery charging, comprising:

connection circuitry for establishing a connection with the battery powered electronic device,

monitoring circuitry for monitoring an existence of an alarm signal transmitted by the battery powered electronic device, and

protection circuitry for performing a protective action in response to the alarm signal.

15. The electric charging device of claim 14, wherein the charging device is a wireless charging device.
