Receivers for Wireless Power Transmission
First Claim
1. A receiver device comprising:
- an antenna element configured to receive one or more power transmission waves that converged to form a pocket of energy and generate an electrical current by harvesting energy from the one or more power transmission waves, wherein the electrical current is in an alternating current form of electricity;
a rectifier coupled to the antenna element and configured to rectify the alternating current form of electricity into a direct current form of electricity;
a power converter coupled to the rectifier and configured to generate a constant voltage output of electrical current in the form of direct current, wherein the power converter is communicatively coupled to an electronic device associated with the receiver, and wherein the receiver provides the direct current to the electronic device; and
a communications component configured to transmit a communication signal to a transmitter device, wherein the communication signal identifies the receiver to the transmitter and indicates the location of the receiver relative to the transmitter.

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.
