  • Patent number: 9985730
    Abstract: A receiving device and a method for operating a receiving device are provided in which a signal is divided into two separate signal parts. The two signal parts are demodulated simultaneously and, from the demodulated signals, the difference is formed. After the formation of the difference, an information item is obtained from the difference signal and compared with a predetermined information item. In the case of correspondence of the obtained information and the compared information, a wake-up signal is generated.

  • Patent number: 8958766
    Abstract: An electronic appliance comprising an electrical circuit and an operating mode switching unit which can be awakened out of a sleep state into a working state in which the current consumption of the circuit is greater in than in the sleep state. To receive a radio signal, the appliance has a receiver comprising a UHF carrier that is amplitude-modulated by a modulation signal. The receiver comprises a UHF antenna connected to a passive filter stage to an input of a passive rectifier circuit. An output of the rectifier circuit is connected to a detector for the modulation signal. To wake the electrical circuit from the sleep state, the operating mode switching unit has a control connection to the detector. The appliance has a low current draw in the sleep state by matching the output impedance of the rectifier circuit to the input impedance of the detector.

  • Publication number: 20130033393
    Abstract: The invention relates to a system having an emitter for emitting a first microwave radiation, a receiver for detecting a second microwave radiation derived from the first microwave radiation and a control system connected to the emitter and the receiver. The first microwave radiation is emitted at a plurality of points in time at different frequencies assigned to the points in time. The correlation of point in time and frequency is random or pseudo-random. Alternatively or additionally, at the point in time, the length of the time period for an emission or reception is random or pseudo-random. The invention further relates to a method for suppressing interference in frequency-modulated radar systems.

  • Patent number: 7714706
    Abstract: The invention relates to the coupling of a sensor element to a transponder, the connection of said sensor element to the transponder being achieved by capacitive or inductive coupling. This enables any separation layer that may lie between the sensor element and the transponder to be retained, allowing the invention to be advantageously used in gas and liquid-tight containers, such as tires. In addition, electrically non-conductive materials of the object to be measured can be used as a dielectric for the capacitive coupling and electrically conductive parts can form part of a conductor loop for the inductive coupling.

  • Publication number: 20090042515
    Abstract: The invention relates to a transponder circuit comprising a high-quality resonator and a demodulator. After being demodulated, the AM-modulated signal emitted by an emitting and receiving appliance has a frequency corresponding to the resonance frequency of the high-quality resonator, for exciting the high-quality resonator. Said transponder circuit also comprises a rectifier, an energy accumulator and a semiconductor circuit which are connected downstream of the resonator. The input impedance of the high-quality resonator is adapted to the loaded impedance of the semiconductor circuit in such a way that a supply voltage for the semiconductor circuit is obtained in the energy accumulator by means of the impedance transformation. Data and/or measuring values can be retrieved and/or updated in a non-contact manner by radio by means of the transponder circuit.

  • Patent number: 7123591
    Abstract: Crosstalk is eliminated in a transceiver which is operated in a frequency-division-multiplex full duplex mode. The technique is suitable in particular for what is referred to as software-defined telecommunications equipment. The frequency division multiplex transceiver has a baseband block, a transmit path and a receive path which respectively transmit and receive on different frequencies (full duplex mode). Furthermore, an auxiliary transmit path is provided which is connected to the receive path and which adds to the received signal a signal whose phase is shifted by 180° with respect to the phase of the crosstalk portion in the first receive path at the summation or superimposition point and which has the same frequency range as the transmit signal. The auxiliary transmit path is driven here, independently of the first transmit path, by the baseband block so as to minimize the crosstalk sensed by the baseband block.

  • Patent number: 6297747
    Abstract: A tool holder for holding a tool has at least one sensor for measuring an operating parameter of the tool holder or the tool during the operation thereof and generating measured value signals which are fed to a signal processing unit for evaluation. The sensor is a surface acoustic wave sensor operating according to acoustic wave principles and its measured value signals are readable in a contactless manner by means of radio waves. The surface acoustic wave sensor requires no current supply circuit but instead draws transmission energy required for transmission of the measured value signals to the signal processing unit from a high frequency interrogation signal, that is transmitted by radio waves from the signal processing unit and is received by the surface acoustic wave sensor.
