摘要： A system, especially an installation, having a vehicle which is maneuverable on a floor is described. The vehicle has an RFID reading device which is connected to an antenna SL, and when the antenna SL enters the coupling region of a floor-installed antenna connected to a stationary RFID transponder, especially an RFID tag, then data stored in the transponder are able to be read out by the reading device. One or more permanent magnet(s) is/are situated on the floor, in particular fixedly joined in the floor, and the vehicle includes a sensor for detecting the direction of the magnetic field.

摘要： In a method for interference suppression of a signal composed of symbols, each symbol is transmitted twice in temporal succession as first symbol and second symbol, so that a segment of a symbol corresponds to a segment of the first symbol and a segment of the second symbol. An interference-suppressed signal is composed from the first and second symbols.

摘要： A method for bus arbitration is for use when working with multi-carrier modulation methods. Each user on a bus is assigned a unique address which identifies the user and which is transmitted upon each initiation of communication. The address is represented as a sequence of binary numerals, the number of bits of the binary numerals being equal to the number of carriers used in the multi-carrier modulation method. This sequence of binary numerals is transmitted successively for the arbitration via the multi-carrier modulation method, a user being eliminated from the arbitration when a further user at the same time has transmitted a binary numeral having higher priority. The transmission of the binary numeral may be repeated if the arbitration of the numeral does not lead to a result in one step. The method for bus arbitration may be used advantageously in a system for contactless energy supply. A redundant sending of phase-shifted signals reduces the failure rate because of random destructive interference.

摘要： In a method for data transmission by orthogonal frequency multiplexing (OFDM) between a transmitter and a receiver using a data signal, the data signal having a telegram, which is made up of OFDM symbols, the OFDM symbols are transmitted by the transmitter in symbol-wise fashion at a rate of repetition n-fold in succession within the telegram, and in the process of receiving in the receiver, the respectively n-fold successively transmitted OFDM symbols are added symbol-wise in phase.
