20210313840 | SYSTEMS AND METHODS OF WIRELESSLY DELIVERING POWER TO A RECEIVER DEVICE - A method of wireless power transmission is provided. The method includes, at a wireless power transmitter, receiving a signal from a receiver device and determining a location of the receiver device based, at least in part, on data included in the signal. The method further includes in response to determining that the location of the receiver device is within a wireless power transmission range of the wireless power transmitter: (I) selecting at least two antennas of the wireless power transmitter's antenna array based, at least in part, on the location of the receiver device, and (II) transmitting, via the at least two antennas of the antenna array, radio frequency power transmission waves that: (i) constructively interfere at the location of the receiver device to produce a focused energy at the location and (ii) destructively interfere around the location of the receiver device to form null-spaces around the focused energy. | 2021-10-07 |
