A position-sensing sensor of a position-sensing system includes first and a second radio transponders that each have a transmitter/receiver connected to an antenna and has a memory for persistent data storage, wherein the first radio transponder has an energy supply source and is selectively switchable into a reduced energy consumption idle state and into an active operating state with complete range of functionality, where during the active operating state, a radio connection to a first radio transponder reader is established for position sensing, where the second radio transponder, which is inductively supplyable with energy by a radio transponder reader, upon entering a range of a second radio transponder reading unit, transfers the first radio transponder from the idle state into the active operating state or transfers position information associated with the second radio transponder to a server of the position-sensing system via the second radio transponder reader.

A method for configuring a communication module of at least one RFID reader that is connected via the communication module to a communication network, wherein the at least one RFID reader is connected to the communication module via a serial interface, wherein configuration information comprising at least communication network address information and device type information is stored in a configuration storage unit of the communication module, where the configuration information stored in the configuration storage unit of the communication module is conveyed via the serial interface to the at least one RFID reader and stored there in a predetermined configuration storage area, and where the configuration information stored in the predetermined configuration storage area of the RFID reader is loaded during a device start of a replacement communication module used instead of the communication module after a successful validity check for configuration of the replacement communication device.

An object tracking system includes a plurality of tags. Each tag includes a mechanism for transmitting a triangulation signal and a position signal that is indicative of a change of position of the respective tag in a time period since a respective reset event. A plurality of triangulation stations receive the triangulation signals from the tags. At least one antenna receives the position signals from the tags. A computer is coupled to the triangulation stations and to the antenna. The computer is programmed to switch between (a) a first tag location algorithm to determine a current location of one of the tags using a differential time of arrival procedure based on the triangulation signal, and (b) a second tag location algorithm to determine a current location of the tag based on the position signal transmitted by the tag and a previous known location of the tag.

To check the useful data of a read-write memory, subsets of the data are formed from the total quantity of useful data, and error-correction data are calculated for each subset of useful data. The subsets of useful data and the corresponding error-correction data are transmitted block-by-block to the read-write memory. During each reading operation, the block containing the desired useful data is read out and the integrity of that data is checked with the aid of the error-correction data.
