Abstract

This disclosure describes methods, apparatus, and systems related to providing wireless power to a wireless device; determining wireless power is no longer required by the wireless device; and disabling one or more functions of at least one of the wireless charging device and the wireless device in response to determining wireless power is no longer required by the wireless device, wherein the disabling includes disabling generation of at least one of a presence pulse and a long beacon extension request pulse at the wireless device.

Claims

1. A computer readable non-transitory medium including instructions stored thereon, which when executed by one or more processor(s) of a wireless charging device, cause the device to perform operations of:

facilitating receipt of wireless power by a wireless device from a wireless charging device;

determining wireless power is no longer required by the wireless device; and

preventing the generation of at least one of a presence pulse or a long beacon extension request pulse by the wireless device in response to the wireless charging device.

2. The medium of claim 1, wherein preventing the generation of at least one of the presence pulse or the long beacon extension request pulse comprises:

disabling a circuit of the wireless device, wherein the circuit is associated with the generation of the presence pulse or the long beacon extension request pulse.

3. The medium of claim 1, wherein determining wireless power is no longer required comprises:

determining at least one of a battery of the wireless device is fully charged or the wireless device is connected to a wired power source.

4. The medium of claim 1, wherein facilitating receipt of wireless power comprises:

determining receipt of a beacon;

causing to transmit a presence pulse to the wireless charging device;

determining a receipt of a magnetic field at a resonator of the wireless device; and

charging a battery of the wireless device using the received magnetic field.

5. The medium of claim 1, wherein determining wireless power is no longer required comprises:

causing to send a charge complete signal to the wireless charging device.

6. The medium of claim 1, wherein preventing the generation of at least one of the presence pulse or the long beacon extension request pulse comprises:

disabling the generation of the presence pulse or a long beacon extension request pulse.

7. The medium of claim 6, wherein the presence pules includes at least two current signals having power difference of at least 0.5 watts.

8. A wireless device, comprising:

at least one memory that stores computer-executable instructions; and

at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to;

facilitate receipt of wireless power by a wireless device from a wireless charging device;

determine wireless power is no longer required by the wireless device; and

prevent the sending of at least one of a presence pulse or a long beacon extension request pulse by the wireless device.

9. The wireless device of claim 8, wherein the instructions to prevent sending of at least one of a presence pulse or a long beacon extension request pulse comprises:

disable a pin in an circuit of the wireless device, wherein the circuit is associated with the generation of the presence pulse or a long beacon extension request pulse.

10. The wireless device of claim 8, wherein the instructions to determine wireless power is no longer required by the wireless device comprises:

determine at least one of a battery of the wireless device is fully charged or the wireless device is connected to a wired power source.

11. The wireless device of claim 8, wherein the instructions to determine wireless power is no longer required by the wireless device comprises:

cause to send a charge complete signal to the wireless charging device.

12. The wireless device of claim 8, wherein the instructions to prevent the sending at least one of the presence pulse or the long beacon extension request pulse comprises:

disable the generation of the presence pulse or a long beacon extension request pulse.

13. The wireless device of claim 8, wherein the presence pules includes at least two current signals having power difference of at least 0.5 watts.

14. The wireless device of claim 13, where the instructions to facilitate receipt of wireless power comprises:

determine receipt of a beacon;

cause to transmit a presence pulse to the wireless charging device;

determine a receipt of a magnetic field at a resonator of the wireless device; and

charge a battery of the wireless device using the received magnetic field.

15. A method comprising:

receiving, by a wireless device, wireless power from a wireless charging device;

determining, by the wireless device, that the wireless power is no longer desired by the wireless device; and

disabling, by the wireless device, at least a portion of a circuit of the wireless device to prevent the sending a presence pulse or a long beacon extension request pulse by the wireless device in response to a beacon received from the wireless charging device.

16. The method claim 15, wherein disabling at least a portion of a circuit of the wireless device comprises:

switching a state of a pin in an circuit of the wireless device, the circuit is associated with the generation of the presence pulse or a long beacon extension request pulse.

17. The method of claim 15, wherein determining wireless power is no longer required comprises:

determining at least one of a battery of the wireless device is fully charged or the wireless device is connected to a wired power source.

18. The method of claim 15, wherein determining wireless power is no longer required comprises:

sending a charge complete signal to the wireless charging device.

19. The method of claim 15, further comprising:

determining the wireless device needs charging; and

enabling, by the wireless device, at least the portion of the circuit of the wireless device to enable the sending a presence pulse or a long beacon extension request pulse by the wireless device in response to a beacon received from the wireless charging device.

20. The method of claim 15, wherein the presence pules includes at least two current signals having power difference of at least 0.5 watts.
