| 摘要 |
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. |

1. A method for multiple pocket-forming in wireless power transmission, the method comprising:
establishing, by a transmitter, a first communication connection associating the transmitter with a first receiver in response to the transmitter receiving a first communication signal from the first receiver; transmitting, by the transmitter, one or more power transmission waves in a direction of the first receiver based on the first communication signal received from the first receiver; adjusting, by the transmitter, a phase of the power transmission waves and a gain of the one or more power transmission waves to converge at a location with respect to the receiver in accordance with the first communication signal received from the first receiver, thereby forming a pocket of energy at the location that the one or more power transmission waves converge; responsive to the transmitter receiving a second communication signal from a second receiver:
establishing, by the transmitter, a second communication connection associating the transmitter with the second receiver; andidentifying, by the transmitter, a second subset of one or more antennas from an array of antennas of the transmitter, wherein the second subset is associated with the second receiver, and wherein a first subset of one or more antennas is associated with the first receiver; andtransmitting, by the transmitter, one or more power transmission waves in the direction of the second receiver based on the second signal received from the second receiver, wherein the second subset of antennas transmits the one or more power transmission waves to the second receiver. |
