METHODS AND APPARATUSES FOR WIRELESS POWER TRANSFER

摘要

This document discusses, among other things, a method for providing wireless power from a power providing device to a portable electronic device. The method includes generating a wireless power signal as a beam having a propagation path directed toward the portable electronic device. The beam can be generated based on parameters for an incoming signal received from the portable electronic device. The wireless power signal can be received by a portable electronic device and converted into operating power for the portable electronic device.
