Techniques For Reducing Messaging Requirements In Wireless Power Delivery Environments

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.

What is claimed is: 
     
         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:
