COMMUNICATION PARTNER APPLIANCE WITH AUTOMATIC SEND MODE ACTIVATION
First Claim
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; and
a processor coupled to the receiver and the detector, wherein the processor is configured to 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.

Abstract
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.

9. 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 command signal includes a request for data from the other communication partner appliance; and a processor coupled to the generator and the transmitter, wherein the processor is configured to switch from the active communication mode to a passive communication mode in response to a determination that the response signal is not received from the other communication partner appliance. - View Dependent Claims (10, 11, 12)

13. A method comprising:
-
making a determination at a first communication partner appliance whether a carrier signal from a second communication partner appliance is present at the first communication partner appliance at a time other than during a transmission of a near-field communication (NFC) command signal from the second communication partner appliance to the first communication partner appliance; and controlling a power supply element of the first communication partner appliance based on the determination whether the carrier signal from the second communication partner appliance is present at the first communication partner appliance, 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. - View Dependent Claims (14, 15, 16, 17)
