Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A communication partner appliance comprising: a transmitter configured to transmit a near-field communication (NFC) command signal to another communication partner appliance according to an active communication mode, wherein the NFC command signal includes a request for data from the another communication partner appliance; and a processor coupled to a generator and the transmitter, wherein the processor is configured to switch from the active communicatio…
