The invention relates to a slave bus subscriber for a serial data bus with a master bus subscriber, wherein the slave subscriber recognizes the bit rate of a data packet received over the data bus, whose header has a sync break field, a sync field and an ID field, with the help of the header of the data packet in such a manner that the periods between falling edges of bits having known bit intervals at least of the sync field and of the sync break field are evaluated and the bit rate is determined from the evaluated periods.

Slave bus subscriber for a serial data bus

To enable a method and a system, having at least one base station and/or one data carrier, for transmitting signals between the base station and a number of mobile data carriers operating in the crypto mode or in the plain mode, wherein [a] the base station emits at least one command signal and/or data signal that is provided with at least one identifying pattern, [b] at least one of the data carriers receives the command signal and/or data signal emitted by the base station that is provided with the identifying pattern, [c] at least one of the data carriers that receive the command signal and/or data signal transmits to the base station a response signal that is a response to the command signal and/or data signal, and [d] the base station receives the response signal transmitted by the data carrier.

Method, system, base station and data carrier for clash-free transmission between a base station and a number of mobile data carriers

In order to provide a method for locating moving objects that will allow high precision in position determination and thus largely eliminate sorting errors, and also to provide a device suitable for executing the method, it is envisaged that on at least one defined location within the reading range of an interrogator () arranged in a stationary position, an interference pulse, which influences a response signal transmitted by a transponder () carried by a moving object () in response to a signal transmitted by the interrogator (), is exerted on the object (), and a position of the object () is determined in dependence on a time when the influence of the response signal occurred.
