First Claim
1. A method for receiving wireless power, comprising:
- receiving, by a receiver, two or more power transmission waves from a transmitter with at least two antennas, the power transmission waves accumulating in the form of constructive interference patterns to form a pocket of energy at a first position of a targeted electronic device coupled to the receiver;
transmitting, by the receiver, a power level and efficiency of the pocket of energy received one or more sensors in the targeted electronic device;
transmitting, by the receiver, a second position of the electronic device to the transmitter for adjusting the pocket of energy determined by the one or more sensors; and
receiving, by the receiver, two or more power transmission waves from the transmitter with at least two antennas, the power transmission waves accumulating in the form of constructive interference patterns to form a pocket of energy at a second position of the targeted electronic device coupled 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.
