Abstract: An integrated circuit is combined with a transponder to function either as a voltage or power supply for the transponder by extracting energy out of an electromagnetic field transmitted by a base station or as a detector in the transponder to act as a remote sensor.

Abstract: When a vehicle travels a bend, tire pressure measurement devices (2) are assigned to wheel positions. For this purpose, it is determined by means of ABS (4) whether it is a left-hand or right-hand bend. Wheel revolution counts are then measured in each tire and sent along with identification codes to a central analysis unit (3). There the wheel revolution counts are collated with the bend data determined by the ABS. The two higher wheel revolution counts are then assigned to the side of the vehicle on the outside of the bend and the two lower wheel revolution counts are assigned to the other side of the vehicle.

Abstract: A system for the detection of a pressure drop in a tire comprising a tire air pressure sensor, a tire temperature sensor and an evaluating unit. The evaluating unit converts the measured air pressure values and temperature values into temperature compensated air pressure values and produces an alarm signal when the temporal fluctuation exceeds an air pressure fluctuation threshold value. The evaluating unit decreases the air pressure threshold value with increasing deviation from the measured temperature compensated air pressure value of a predetermined temperature compensated air pressure reference value. At least one further sensor may be provided for measuring a parameter which influences the air pressure in the tire whereby the evaluating unit corrects the measured and, regarding to the production of an alarm signal, evaluated air pressure according to this parameter.
