METHODOLOGY FOR POCKET-FORMING
First Claim
1. A method for transmitting wireless power, the method comprising:
- transmitting, by a transmitter device, a plurality of power transmission waves, wherein the transmitter comprises a plurality of antennas configured to transmit the plurality of power transmission waves;
determining, by the transmitter, a constructive interference pattern associated with the power transmission waves based on a location of a receiver; and
automatically adjusting, by the transmitter, transmission of the plurality of power transmission waves to converge based on the constructive interference pattern, thereby establishing a pocket of energy relative to the location of 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.

16. A transmitter device for wireless power transmission comprising:
-
an array of one or more antennas configured to transmit one or more power transmission waves, wherein at least one antenna is configured to receive one or more communication signals from one or more receivers; and a processor configured to determine a constructive interference pattern associated with the one or more power transmission waves based on a target location to establish a pocket of energy, and to adjust based on data in the one or more communication signals, transmission of the one or more power transmission waves to converge the one or more power transmission waves according to the constructive pattern, thereby establishing the pocket of energy at the target location. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
