Abstract: Data carriers for inventorying by means of a communication station, whereby the communication station and each data carrier are brought into communicative connection, and each data carrier brought into communicative connection with the communication station is configured to generate a response signal that renders possible an inventorying of the data carrier and is capable of delivering a generated response signal with the use of a transmission start moment that can be selected from a plurality of transmission start moments, each data carrier tests whether another data carrier is already giving its response signal. Each data carrier is configured to discontinue the generation or delivery of its response signal if another data carrier is already providing its response signal.
Abstract translation: 用于通过通信站进行库存的数据载体，由此使通信站和每个数据载体进行通信连接，并且与通信站进行通信连接的每个数据载体被配置为产生响应信号，其使得可能的库存 数据载体并且能够通过使用可以从多个传输开始时刻中选择的传输开始时刻来传递所生成的响应信号，每个数据载体测试另一个数据载体是否已经提供其响应信号。 如果另一数据载体已经提供其响应信号，则每个数据载体被配置为中止其响应信号的产生或传递。

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.
Abstract translation: 通信伙伴设备在近场通信系统中实现。 通信伙伴设备包括接收器，检测器和处理器。 接收器从另一通信伙伴设备接收NFC命令信号。 检测器检测在来自另一个通信伙伴设备的NFC命令信号的传输期间，来自另一通信伙伴设备的载波信号是否存在于接收机处，而不是在从另一个通信伙伴设备传输到接收机的时间。 处理器基于检测器的确定来控制电源元件，来自另一通信伙伴设备的载波信号是否存在于接收机。 电源元件被配置为建立到第一电源或第二电源的连接。 第一电源取决于载波信号，第二电源与载波信号无关。

Abstract: Embodiments of a method for clock synchronization in a radio frequency identification (RFID) equipped device, an RFID equipped device, and a hand-held communications device are described. In one embodiment, a method for clock synchronization in an RFID equipped device involves measuring a difference between a field clock frequency generated from an external clock and an internal clock frequency generated from an internal clock and generating outgoing bits in the RFID equipped device in response to the measured difference. Generating the outgoing bits involves adjusting the bit length of at least one of the outgoing bits in response to the measured difference. Other embodiments are also described.
