  • Detection of a low pressure condition of a vehicle tire
    Patent number: 4578992
    Abstract: A tire pressure indicating device includes a coil, and mounted in a tire forming with a capacitor to form a passive oscillatory circuit. The circuit is energized by pulses supplied via a coil positioned outside the tire and secured to the vehicle and the frequency in the passive oscillatory circuit is varied with tire pressure due to changes caused to the capacitance value of the capacitor. The frequency in the passive oscillatory circuit is sensed via a coil positioned outside the tire and secured to the vehicle.
