Abstract

Techniques are described for retention of known data within a wireless power transmission system, or within a cloud-based processing system. In order to perform scheduling procedures for determining which device to power, it is necessary to collect data regarding a device, e.g., the battery type, power usage, device model, present charge level and amount of power delivered per power cycle. A wireless power receiver client typically needs to collect or infer the information from the device and then provide the information directly to the charger via a messaging protocol. In existing wireless power transmission systems, information is re-transmitted to the wireless power transmission system every time the receiver engages or reengages the system.

Claims

1. A method of reducing messaging in a wireless power delivery environment, the method comprising:

responsive to a first discovery event, receiving, by a wireless power transmission system, a first communication including a receiver identifier (ID) that uniquely identifies a first wireless power receiver client associated with a first device in the wireless power delivery environment;

receiving device information corresponding to the first device;

associating the receiver ID with device information corresponding to the first device;

responsive to a subsequent discovery event, receiving a second communication including the receiver ID that uniquely identifies the first wireless power receiver client associated with the first device in the wireless power delivery environment; and

retrieving the device information corresponding to the first device from a device registry using the receiver ID.

2. The method of claim 1, further comprising:

responsive to associating the receiver ID with device information corresponding to the first device, storing the associated receiver ID with the device information in the device registry.

3. The method of claim 2, wherein the device registry is stored on the wireless power transmission system.

4. The method of claim 2, wherein the device registry is stored on a cloud-based processing system.

5. The method of claim 1, further comprising:

prior to receiving the device information corresponding to the first device, processing the receiver ID to determine if the first device is a known device; and

sending a request for the device information for delivery to the first power receiver client when the first device is a known device.

6. The method of claim 1, further comprising:

generating a wireless power delivery schedule for the wireless power transmission system,

wherein the wireless power delivery schedule includes the first wireless power receiver client.

7. The method of claim 1, wherein a discovery event comprises an indication that the first device is available for receiving wireless power within the wireless power delivery environment.

8. The method of claim 1, wherein the receiver ID comprises a radio ID.

9. The method of claim 8, wherein the radio ID is associated with a model number.

10. The method of claim 9, wherein the model number indicates one or more of a battery capacity or a device type of the first device.

11. A method of reducing messaging in a wireless power delivery environment, the method comprising:

responsive to a first discovery event, processing a first communication including a receiver identifier (ID) that uniquely identifies a first wireless power receiver client associated with a first device in the wireless power delivery environment;

receiving device information corresponding to the first device;

associating the receiver ID with device information corresponding to the first device; and

storing the associated receiver ID with the device information in a device registry.

12. The method of claim 11, further comprising:

responsive to a subsequent discovery event, receiving the receiver ID that uniquely identifies the first wireless power receiver client associated with the first device in the wireless power delivery environment; and

retrieving the device information corresponding to the first device from the device registry using the receiver ID.

13. The method of claim 11, further comprising:

responsive to associating the receiver ID with device information corresponding to the first device, storing the associated receiver ID with the device information in the device registry.

14. The method of claim 13, wherein the device registry is stored, in whole or in part, on the wireless power transmission system and on a cloud-based processing system.

15. The method of claim 11, further comprising:

prior to receiving the device information corresponding to the first device, processing the receiver ID to determine if the first device is a known device; and

sending a request for the device information for delivery to the first power receiver client when the first device is a known device.

16. The method of claim 15, further comprising querying a cloud-based processing system to determine if the first device is a known device.

17. The method of claim 11, further comprising:

generating a wireless power delivery schedule for the wireless power transmission system,

wherein the wireless power delivery schedule includes the first wireless power receiver client.

18. The method of claim 11, wherein the receiver ID comprises a radio ID, wherein the radio ID is associated with a model number that indicates one or more of a battery capacity or a device type of the first device.

19. A wireless power transmission system, comprising:

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

control circuitry configured to;

responsive to a first discovery event, process a first received communication including a receiver identifier (ID) that uniquely identifies a first wireless power receiver client associated with a first device in the wireless power delivery environment;

process device information corresponding to the first device;

associate the receiver ID with device information corresponding to the first device;

responsive to a subsequent discovery event, process a second communication including the receiver ID that uniquely identifies the first wireless power receiver client associated with the first device in the wireless power delivery environment; and

retrieve the device information corresponding to the first device from a device registry using the receiver ID.

20. The wireless power transmission system of claim 19, wherein the control circuity is further configured to:

responsive to associating the receiver ID with device information corresponding to the first device, store the associated receiver ID with the device information in the device registry.
