Patent attributes
A system for wireless-power transmission includes a radio-frequency wireless-power transmitter that is in communication with a sensor for acquiring data for motion recognition and tracking of a plurality of objects within at least a portion of a transmission field of the radio-frequency wireless-power transmitter; and one or more processors of the radio-frequency wireless-power transmitter configured to: detect location and displacement of an object of the plurality of objects within the transmission field; and send instructions to cause adjustments to transmission of one or more radio-frequency power-transmission waves by the radio-frequency wireless-power transmitter to a receiving electronic device based on the location and displacement of the object. The receiving electronic device is configured to use energy from the one or more radio-frequency power-transmission waves to (i) power the receiving electronic device and/or (ii) to charge a power source of the receiving electronic device.
