Abstract

In an aspect, a wireless power transfer system includes at least one powering device and at least one powered device. Each powering device includes powering circuitry for wireless power transfer to the powered device. Each powered device includes powered circuitry for reception of the wireless power transfer from the powering device. The powering device may include communication circuitry for a close-range wireless communication with the powered device, while the powered device may also include communication circuitry for the close-range wireless communication with the powering device, so as for the powering device and the powered device to discover each other through the communication. The powering device and powered device may conditionally activate and deactivate the powering circuitry and powered circuitry, respectively, based on the discovery using the close-range wireless communication.

Claims

1. A method, comprising:

providing a powering device having powering circuitry for wireless power transfer;

providing a powered device having powered circuitry for reception of the wireless power transfer; and

conditionally activating and deactivating the powering circuitry and powered circuitry for optimizing the wireless power transfer.
