  • Arrangement for monitoring at least one parameter for a number of motor vehicle wheels
    Patent number: 6980099
    Abstract: The arrangement for monitoring at least one parameter for a number of motor vehicle wheels uses at least one receiver antenna that features a directional characteristic such that at least the signals which are transmitted by detector units located at two different vehicle wheels can be uniquely assigned to the relevant wheel positions as a result of the different receive level. The use of a number of receiver antennas allows either the number of distinguishable detector units to be increased or a redundancy to be created to improve the reliability of the detection.
    Type: Grant

  • Antenna, in particular for an anti-theft system of a motor vehicle
    Patent number: 5844524
    Abstract: An antenna is constructed as an "on-board antenna" in the form of conductor tracks on a circuit board. A conductor track on the upper surface of the circuit board is electrically connected to a conductor track on the lower surface thereof through plated-through holes. This increases both the effective antenna surface area and thus the radiation power.
