TRACKING SURFACE FOR DETERMINING OPTIMAL CHARGING POSITION
First Claim
1. A method for transmitting wireless power, comprising:
- generating two or more RF waves from a transmitter with at least two RF transmit antenna;
forming controlled constructive and destructive interference patterns from the generated RF waves;
accumulating energy or power in the form of constructive interference patterns from the RF waves to form pockets of energy;
converging the pockets of energy in 3-d space to a targeted electronic device;
sensing the converging pockets of energy for determining the power level and efficiency received by the targeted electronic device; and
maintaining or changing the electronic device position for maximizing the efficiency of receiving the converged pockets of energy in a receiver connected to the electronic device with at least one antenna for powering the targeted electronic device from the pockets of energy.

Abstract
The present disclosure describes a methodology for tracking position and orientation of one or more electronic devices, which may receive charge through wireless power transmission based on pocket-forming. This methodology may include one transmitter and at least one or more receivers, being the transmitter the source of energy and the receiver the device that is desired to charge or power. The transmitter may identify and locate the device to which the receiver is connected for subsequently charge and/or charge it. In order to increase charging and/or powering of electronic devices, a plurality of sensors may provide information determining the optimal position and/or orientation aimed to receive charge and/or power at the maximum available efficiency.
