摘要： A method for wireless data transmission between a base station and one or more, in particular passive, transponders is provided, in which electromagnetic carrier waves are emitted by the base station. Data comprising successive characters are transmitted from a respective transponder to the base station by modulation and backscattering of the electromagnetic carrier waves, and a respective one of the characters is coded and transmitted by a respective transponder within a predefined time interval. Within at least one of the predefined time intervals, a safeguard character formed from the data to be transmitted is transmitted in addition to the character to be transmitted.

摘要： A method and apparatus for transmitting data in a radio frequency identification system, which includes a reader and at least one transponder, is provided. The reader transmits data sequences to the transponder including at least command data, associated check data, and a subsequent return link header data. Upon receiving unrecognized command data and/or unsupported parameter and address data the transponder notifies the reader of this condition. The notification takes place at times when the reader transmits end signals indicating an end of a data sequence, transmits an optional parameter and address data, or transmits the return link header data. Thus, communication between the reader and other transponders is not disrupted when a transponder cannot execute a command.

摘要： In certain embodiments, a method comprises receiving a data transmission comprising a header with a symbol and at least one symbol delimiter. The method may comprise monitoring the received data transmission to determine whether a time period between successive symbol delimiters of the header exceeds a maximum time. The method may comprise resetting a transponder to an initial state if the time period exceeds the maximum time. The maximum time may be determined based at least in part on the symbol after receiving successive symbol delimiters.

摘要： A method and apparatus is provided for data transmission in RFID and remote sensor systems with at least one reader and a plurality of transponders or remote sensors being located in an electromagnetic field of the reader, in which a multipart return link header containing transmission parameters for the return link, such as timing or modulation references, is transmitted at the beginning of a return link transmission of useful data from a transponder or sensor to a reader. A relative time duration of individual subsymbols of the return link header is modified to select a data transfer mode from among a number of different data transfer modes. A combination of different return link transmission mechanisms is thereby possible, whereby these are mutually compatible and moreover are simple to realize in terms of circuitry and control engineering.

摘要： A method for recognizing time-variable functional states, e.g., in the course of a programming process, in RFID systems is disclosed, which includes at least one transponder or remote sensor and at least one base station, which transmits data and/or power to the transponder or sensor by a carrier signal. According to the invention, after a specified process state is attained at least one confirmation symbol is transmitted by the transponder or sensor to the base station. As a result, no unfavorable “worst case” scenario has to be provided for chronologically controlling time-variable processes because the base station is able to clearly recognize the beginning and end of the process, as well as the state thereof. RFID systems or remote sensor systems can thus be controlled more quickly and more reliably, resulting especially in reduced costs.
