摘要： A communication partner appliance is implemented within a near field communication system. The communication partner appliance includes a receiver, a detector, and a processor. The receiver receives a NFC command signal from another communication partner appliance. The detector detects whether a carrier signal from the other communication partner appliance is present at the receiver at a time other than during a transmission of the NFC command signal from the other communication partner appliance to the receiver. The processor controls a power supply element based on a determination by the detector whether the carrier signal from the other communication partner appliance is present at the receiver. The power supply element is configured to establish a connection to either a first power supply or a second power supply. The first power supply is dependent on the carrier signal, and the second power supply is independent of the carrier signal.

摘要： Systems and methods for performing both wireless communications and wireless sensing in combination are disclosed herein. In one example embodiment, the system includes a base station (BS) including each of at least one antenna device including a first antenna device and at least one control unit. The control unit includes an input port coupled at least indirectly to the first antenna device, an output port, and a controllable circuit including each of a spillover cancellation circuit and a bypass circuit. The BS is configured to operate in each of a communication mode and a sensing mode. When the BS operates in the sensing mode, the spillover cancellation circuit of the controllable circuit is enabled and performs spillover cancellation. When the BS operates in a communication mode, the bypass circuit operates so that the spillover cancellation circuit is bypassed or otherwise does not affect how the output signal is generated.
