Abstract

The wireless power transmission is a system for providing wireless charging and / or primary power to electronic / electrical devices via microwave energy. The microwave energy is focused to a location in response to receiving a beacon signal from a beacon device by a power transmitter having one or more adaptively-phased microwave array emitters. Rectennas within the device to be charged receive and rectify the microwave energy and use it for battery charging and / or for primary power.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Application No. 12 / 861,526, filed August 23, 2010, which is a continuation-in-part of U.S. Patent Application Serial No. 11 / 812,060, filed June 14, 2007, Their contents are hereby deemed fully incorporated into this application by reference. technical field [0003] The present invention relates generally to power transfer systems and battery chargers, and more particularly to methods and systems for wireless power transfer to power devices requiring power via microwave transmission. Background technique [0004] Many portable electronic devices are powered by batteries. Rechargeable batteries are often used to avoid the cost of replacing conventional dry batteries and to conserve valuable resources. However, recharging batteries with conventional rechargeable battery chargers requires access to an alternating current (A.C.) power outlet, which is sometimes unav...
