SYSTEMS AND METHODS FOR WIRELESS POWER TRANSMISSION
First Claim
1. A method for transmitting wireless power comprising:
- determining, by a transmitter, whether a first wireless power receiver coupled to a first electronic device is within range of the transmitter;
transmitting, by the transmitter, a communication signal to the first wireless power receiver to identify a location the of first wireless power receiver relative to a transmission antenna array;
receiving, by the transmitter, a communication signal from the receiver identifying the location of the first wireless power receiver;
assigning, by the transmitter, a first set of a plurality of antennas to the first wireless power receiver coupled to a first electronic device based on the location of the first electronic device; and
generating, by the transmitter, two or more power transmission waves with the first set of the plurality of antennas forming controlled constructive interference patterns that converge at the location first wireless power 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.
