    摘要： An RF signal generator wirelessly transferring power to a wireless device includes, in part, a multitude of generating elements generating a multitude of RF signals transmitted by a multitude of antennas, a wireless signal receiver, and a control unit controlling the phases and/or amplitudes of the RF signals in accordance with a signal received by the receiver. The signal received by the receiver includes, in part, information representative of the amount of RF power the first wireless device receives. The RF signal generator further includes, in part, a detector detecting an RF signal caused by scattering or reflection of the RF signal transmitted by the antennas. The control unit further controls the phase and/or amplitude of the RF signals in accordance with the signal detected by the detector.

    摘要： A method of generating a DC power from incident RF waves, includes, in part, measuring the amount of power being received by a device generating the DC power, and controlling the phases of the RF waves being transmitted by a multitude of RF transmitters in accordance with the measured power. A programmable test load is optionally used at the device to measure the received power. The device optionally includes, an antenna, an RF-to-DC converter to generate the DC power, an impedance matching/transformation circuit, and an RF load/matching circuit.

    摘要： A device includes, in part, an antenna adapted to receive an RF signal that includes modulated data, a splitter/coupler adapted to split the received RF signal, a receiver adapted to demodulate the data from a first portion of the RF signal, and a power recovery unit adapted to convert to a DC power a second portion of the RF signal. The splitter/coupler is optionally adjustable to split the RF signal in accordance with a value that may be representative of a number of factors, such as the target data rate, the DC power requirement of the device, and the like. The device optionally includes a switch and/or a power combiner adapted to deliver all the received RF power to the receiver depending on any number of operation conditions of the device or the device's distance from an RF transmitting device.
