METHOD FOR 3 DIMENSIONAL POCKET-FORMING
First Claim
1. A method for 3-dimensional pocket-forming in wireless power transmission, comprising the steps of:
- capturing a first signal from a receiver with a first subset of antennas from an antenna array on a transmitter;
switching to a different subset of antennas on the transmitter;
capturing a second signal from the receiver with a second subset of antennas from the antenna array on the transmitter; and
processing the first and second signals by a microprocessor on the transmitter in order to adjust the antenna array on the transmitter to form pockets of energy directed to the receiver to charge or power an electronic device.

Abstract
The present disclosure describes a methodology for wireless power transmission based on pocket-forming. The method includes a transmitter device capable of forming pockets of energy used by a receiver device to charge an electronic device such as a computers, cell phones, tablet and/or devices of the like. The method may include using an array of antennas at the transmitter to locate the position of a receiver device. The transmitter may identify the position of the device by capturing a signal from a receiving device using two subsets from the array of antennas. The subset of antennas may then be adjusted to form pockets of energy at the appropriate location of the receiving device. Previously stored data pertaining to each antenna in the array may serve to determine the proper adjustments for the entire array of antennas based on the results from the subsets used to capture the receivers signal.
