  • Patent number: 8102303
    Abstract: A method for distance measurement and data transmission in a continuous wave radar system is described. A continuous wave radar system has a transmit and receive module and at least one transponder device, a mobile control and monitoring device and an HMI system. Transponder devices are searched for with the aid of an unmodulated continuous wave signal as an interrogation signal, such that the transponder device can send a radio response signal to the transmit and receive module in response to the interrogation signal, as a result of which a data transmission takes place from the transponder device to the transmit and receive module. Upon completion of the data transmission a frequency-modulated continuous wave signal is generated in order to measure, on the basis thereof, a distance between the transponder device and the transmit and receive module.

  • Patent number: 7016647
    Abstract: A method and system for transferring data between at least one read/write device (RWD) and at least one mobile data memory (MDM). The mobile data memory (MDM) is preferably attached to an object for recording object-related status and/or process data, e.g. in a dispatch, transport and/or manufacturing system for the individual objects. According to the method, a difference in transfer time between the received data signals of a mobile data memory (MDM) and transmitted data signals of the read/write device (RWD) is determined in the read/write device (RWD) and the received data signals of the mobile data memory (MDM) are processed further in said read/write device (RWD) only if the difference in transfer time which has been determined lies within a predefined transfer time limit.

  • Patent number: 6944240
    Abstract: A method and circuit for transmitting a data-modulated high-frequency data signal fC from a transmitter to a receiver, for transmitting data between a read-write device (RWD) and at least one mobile data memory (MDM) in an identification system that has a number of mobile data memories (MDM) which are placed on objects and which are provided for detecting object-specific status data and/or process data. Such an identification system is particularly useful, e.g., in a shipping, transport and/or manufacturing system of the individual objects. In addition to the transmitted high frequency data signal fC, a further high-frequency data signal fS is transmitted, which serves to convert the frequency and/or to modulate the carrier code of the high-frequency data signal fC.
