摘要： Aspects are described for a device comprising a wireless transceiver configured to receive a radio frequency (RF) emission from a source device, an energy-harvesting unit configured to charge the first device wirelessly, using a first part of the RF emission, and a processor communicatively coupled to the transceiver. The processor is configured to modulate the first part of the RF emission based on information detected by the device and determine that an energy level of the device is above a threshold. The processor is further configured to transmit, in response to determining that the energy level is above the threshold, using the wireless transceiver, the modulated first part of the RF emission to the source device. The processor is further configured to transmit, in response to determining that the energy level is above the threshold, using the wireless transceiver, a second part of the RF emission wirelessly to another device to charge the other device.

摘要： A signal transfer device includes a signal transmitter, a first amplitude adjustment means, an adjustment signal output means, a detector and a second amplitude adjustment means. The signal transmitter outputs signals to first and second transfer paths based on single-phase or differential input signal. The first amplitude adjustment means adjusts at least one of amplitudes of the signals transferred to the first and second transfer paths based on a predetermined amplitude ratio. The adjustment signal output means outputs adjustment signals to the first and second transfer paths. The detector detects the adjustment signals. The second amplitude adjustment means adjusts at least one of the amplitudes of the signals transferred to the first and second transfer paths based on detection result of the detector.

摘要： A signal processing unit includes a substrate (20) with a ground component (20c), a signal processor (10) on the substrate with an oscillator (3), and a conductive housing (22). The conductive housing is connected to a first site of the ground component and to a second site, and configured such that a first area overlaps at least part of a second area. The first area is in a position that is an odd-numbered multiple of 1/4 wavelength of oscillation away from the first site. The second area is, when the second site is located at the ground component, in a position that is an even-numbered multiple of 1/4 wavelength of oscillation away from the second site, or, when the second site is the open end of the extension line, in a position that is an odd-numbered multiple of 1/4 wavelength of oscillation away from the second site.

摘要： The invention concerns a signal transmission device 1 including a signal sender 2 that sends first and second transmission signals S(+), S(-) of mutually opposite phases, a first transmission path 31 over which the first transmission signal S(+) is transmitted, a second transmission path 32 over which the second transmission signal S(-) is transmitted, and a signal receiver that converts the first transmission signal received from the first transmission path and the second transmission signal received from the second transmission path into an output signal Sout of a single phase. The signal transmission device differentiates each amplitude of the first and second transmission signals sent from the signal sender, and the signal receiver, based on an amplitude ratio of the first and second transmission signals, converts the received first and second transmission signals.
