METHOD FOR 3 DIMENSIONAL POCKET-FORMING
First Claim
1. A method of forming a pocket of energy, the method comprising:
- capturing, by a transmitter, a first signal from a receiver, wherein the first signal is captured by a first subset of antennas of the transmitter;
transmitting, by the transmitter, one or more power transmission waves to the receiver based on data contained in the first signal, wherein the one or more power transmission waves are transmitted using the first subset of antennas;
capturing, by the transmitter, a second signal from the receiver, wherein the second signal is captured by a second subset of antennas of the transmitter; and
transmitting, by the transmitter, the one or more power transmission waves to form a pocket of energy at a location relative to the receiver based on the first and second signals, wherein the transmitter continuously adjusts the first subset of antennas and the second subset of antennas to form the pocket of energy at the location relative to the receiver.

Abstract
The embodiments described herein include a transmitter that transmits a power transmission signal (e.g., radio frequency (RF) signal waves) to create a three-dimensional pocket of energy. At least one receiver can be connected to or integrated into electronic devices and receive power from the pocket of energy. The transmitter can locate the at least one receiver in a three-dimensional space using a communication medium (e.g., Bluetooth technology). The transmitter generates a waveform to create a pocket of energy around each of the at least one receiver. The transmitter uses an algorithm to direct, focus, and control the waveform in three dimensions. The receiver can convert the transmission signals (e.g., RF signals) into electricity for powering an electronic device. Accordingly, the embodiments for wireless power transmission can allow powering and charging a plurality of electrical devices without wires.
