Wireless power transfer apparatus and method thereof

Abstract

In accordance with various aspects of the disclosure, a method and apparatus is disclosed that includes features of a receiving antenna configured to wirelessly receive power transmitted by a transmitting device and arranged to associate or dissociate with the transmitting device.

What is claimed is: 
     
         1 . An apparatus comprising:
 a power receiving unit (PRU) configured to wirelessly receive power transmitted by a power transmitting unit (PTU), the received power to be used by the PRU to provide operational power for the PRU and/or to charge a battery in the PRU,   wherein the PRU is also configured to wirelessly receive at least one command from the PTU through a Bluetooth link and to wirelessly transmit at least one parameter to the PTU through the Bluetooth link.   
     
     
         2 . The apparatus of  claim 1 , further comprising a Bluetooth radio. 
     
     
         3 . The apparatus of  claim 1 , wherein the at least one parameter comprises a charge status of the battery. 
     
     
         4 . The apparatus of  claim 1 , wherein the PRU further comprises a switch to regulate the received power. 
     
     
         5 . The apparatus of  claim 4 , wherein the at least one command is to be used to control the switch. 
     
     
         6 . A method comprising:
 wirelessly receiving power transmitted by a power transmitting unit (PTU);   using the received power to provide operational power and/or to charge a battery; and   wirelessly receiving at least one command from the PTU through a Bluetooth radio and wirelessly transmitting at least one parameter to the PTU through the Bluetooth radio.   
     
     
         7 . The method of  claim 6 , wherein the at least one parameter comprises a charge status of the battery. 
     
     
         8 . The method of  claim 6 , further comprising using a switch to regulate the reception of power. 
     
     
         9 . The method of  claim 8 , further comprising using the at least one command to control the switch. 
     
     
         10 . An apparatus comprising:
 a power transmitting unit (PTU) configured to wirelessly transmit power to be received by a power receiving unit (PRU),   wherein the PTU is further configured to wirelessly transmit at least one command to the PRU through a Bluetooth link and to wirelessly receive at least one parameter from the PRU through the Bluetooth link.   
     
     
         11 . The apparatus of  claim 10 , further comprising a Bluetooth radio. 
     
     
         12 . The apparatus of  claim 10 , wherein the at least one parameter comprises a charge status of a battery in the PRU. 
     
     
         13 . The apparatus of  claim 10 , wherein the at least one command is to be used to control a switch in the PRU for regulating reception of the power by the PRU. 
     
     
         14 . A method comprising:
 wirelessly transmitting power to be received by a wireless power receiving unit (PRU); and   using a Bluetooth radio to transmit at least one command to the PRU and to receive at least one parameter from the PRU.   
     
     
         15 . The method of  claim 14 , wherein the at least one parameter comprises a charge status of a battery in the PRU. 
     
     
         16 . The method of  claim 14 , wherein the at least one command is to be used to control a switch in the PRU for regulating the reception of power in the PRU.
