Abstract

Techniques are described herein for determining which power receiver clients are within a set network and limiting power transmission to these select clients. Ignoring some power requests frees up the wireless power transmission system to preferentially supply power to wireless power receiver clients that are determined to be of higher importance. This may be particularly beneficial within a home or business setting where the wireless power transmission system coverage region extends into locations where unknown devices are located.

Claims

1. A method of scheduling power delivery for a wireless power transmission system, the method comprising:

responsive to broadcasting a network sharing message a wireless power delivery environment, receiving, by the wireless power transmission system, a wireless power consumption request initiated by a first wireless power receiver in the wireless power delivery environment,

wherein the wireless power consumption request uniquely identifies the first wireless power receiver;

determining that the first wireless power receiver does not belong to a set of wireless power receivers synchronized with the wireless power transmission system for wireless power delivery;

determining, based on current charging demands, that the first wireless power receiver can be added to a wireless power delivery schedule for the wireless power transmission system; and

modifying the wireless power delivery schedule for the wireless power transmission system to include the first wireless power receiver with a lower priority than the wireless power receivers that belong to the set of wireless power receivers synchronized with the wireless power transmission system.

2. The method of claim 1, further comprising:

querying the wireless power delivery schedule to identify the current charging demands.

3. The method of claim 1, wherein the wireless power delivery schedule includes multiple tiers of wireless power receivers.

4. The method of claim 3, wherein the multiple tiers of wireless power receivers comprise at least a first tier and a second tier, and wherein wireless power receivers in the first tier have a higher priority than wireless power receivers in the second tier by the wireless power transmission system when generating the wireless power delivery schedule.

5. The method of claim 1, further comprising:

providing wireless power to the wireless power receivers in the wireless power delivery environment that are included in the wireless power delivery schedule.

6. The method of claim 1, further comprising:

synchronizing the first wireless power receiver with the wireless power transmission system for wireless power delivery.

7. The method of claim 6, wherein the synchronizing the first wireless power receiver with the wireless power transmission system for wireless power delivery comprises registering the first wireless power receiver with the wireless power transmission system.

8. The method of claim 6, wherein the synchronizing the first wireless power receiver with the wireless power transmission system for wireless power delivery comprises registering the first wireless power receiver with a cloud-based system.

9. The method of claim 6, wherein the synchronizing the first wireless power receiver with the wireless power transmission system for wireless power delivery comprises sharing credentials of the first wireless power receiver with the wireless power transmission system.

10. The method of claim 6, wherein the synchronizing the first wireless power receiver with the wireless power transmission system for wireless power delivery comprises activating a synchronization button on the first wireless power receiver and the wireless power transmission system with a predetermined period of time of each other.

11. The method of claim 6, wherein the synchronizing the first wireless power receiver with the wireless power transmission system for wireless power delivery comprises obtaining information from a user of the first wireless power receiver.

12. The method of claim 6, wherein the synchronizing the first wireless power receiver with the wireless power transmission system for wireless power delivery comprises obtaining payment information.

13. A wireless power transmission system, comprising:

an adaptively-phased antenna array having multiple radio frequency (RF) transceivers;

control circuitry configured to;

process a wireless power consumption request initiated by a first wireless power receiver in the wireless power delivery environment, wherein the wireless power consumption request uniquely identifies the first wireless power receiver;

determine that the first wireless power receiver does not belong to a set of wireless power receivers synchronized with the wireless power transmission system for wireless power delivery;

determine, based on current charging demands, that the first wireless power receiver can be added to a wireless power delivery schedule for the wireless power transmission system; and

modify the wireless power delivery schedule for the wireless power transmission system to include the first wireless power receiver with a lower priority than wireless power receivers that belong to the set of wireless power receivers synchronized with the wireless power transmission system.

14. The wireless power transmission system of claim 13, wherein the control circuitry is further configured to:

query the wireless power delivery schedule to identify the current charging demands.

15. The wireless power transmission system of claim 13, wherein the wireless power delivery schedule includes multiple tiers of wireless power receivers, the multiple tiers of wireless power receivers comprising at least a first tier and a second tier, and wherein wireless power receivers in the first tier have a higher priority than wireless power receivers in the second tier by the wireless power transmission system when generating the wireless power delivery schedule.

16. The wireless power transmission system of claim 13, wherein the control circuitry is further configured to provide wireless power to the wireless power receivers in the wireless power delivery environment that are included in the wireless power delivery schedule.

17. The wireless power transmission system of claim 13, wherein the control circuitry is further configured to synchronize the first wireless power receiver with the wireless power transmission system for wireless power delivery.

18. A non-transitory computer-readable storage medium having program instructions stored thereon which, when executed by one or more processors, cause the one or more processors to:

process a wireless power consumption request initiated by a first wireless power receiver in the wireless power delivery environment, wherein the wireless power consumption request uniquely identifies the first wireless power receiver;

determine that the first wireless power receiver does not belong to a set of wireless power receivers synchronized with the wireless power transmission system for wireless power delivery;

determine, based on current charging demands, that the first wireless power receiver can be added to a wireless power delivery schedule for the wireless power transmission system; and

modify the wireless power delivery schedule for the wireless power transmission system to include the first wireless power receiver with a lower priority than the wireless power receivers that belong to the set of wireless power receivers synchronized with the wireless power transmission system.

19. The non-transitory computer-readable storage medium of claim 18, wherein the program instructions, when executed by the one or more processors, further cause the one or more processors to:
