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： An electrical signal transformation device (100) configured for emulation of physical, for example, optical, phenomena and/or a mathematical or logical process. The device employs a first plurality (X oriented Li j ) , second plurality (Y oriented Lij) and third plurality (Cij) of electrical components each having a first terminal and a second terminal. The first plurality and second plurality of electrical components are arranged along a first direction (X) and a second direction (Y) respectively, to form a planar two dimensional lattice (110) . The first plurality of electrical components (X oriented Lij) are configured to provide at least one of a constant signal propagation velocity and/or amplitude while the second plurality of electrical components (Y oriented Lij ) are configured to provide at least one of a varying signal propagation velocity and/or amplitude. The lattice includes at least two input signal nodes and at least one output signal node and is configured to transform and communicate a plurality of input signals from the input node to the output node .

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.

摘要： An RF lens includes a multitude of radiators adapted to transmit radio frequency electromagnetic EM waves whose phases are modulated so as to concentrate the radiated power in a small volume of space in order to power an electronic device positioned in that space. Accordingly, the waves emitted by the radiators are caused to interfere constructively at that space. The multitude of radiators are optionally formed in a one-dimensional or two-dimensional array. The electromagnetic waves radiated by the radiators have the same frequency but variable amplitudes.
