Abstract:
1. A communication partner appliance comprising: a receiver to receive a near field communication (NFC) command signal from another communication partner appliance; a detector coupled to the receiver, wherein the detector is configured to detect 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, causing a status signal to be generated; and a processor coupled to the receiver and the detector, wherein the processor is configured to receive the status signal from the detector and control 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, wherein the power supply element is configured to establish a connection to either a first power supply or a second power supply, wherein the first power supply is dependent on the carrier signal, and the second power supply is independent of the carrier signal.
