Abstract
A tire-monitoring device comprises, on a wheel of a vehicle, a converter stage which processes an electric signal representing measurements of the pressure and/or temperature of the tire in pulse form and a stage for transmitting the signal to the vehicle by inductive coupling. In order to minimize the consumption of electric energy by circuit components on the wheel, a solid state switch responsive to the transmission of energy from the vehicle to the wheel disconnects the circuit components on the wheel from the energy source. Also, in order to further minimize the consumption of electrical energy, only the positions of the ascending and descending fronts of the electric signal pulses representing the measurements are transmitted to the vehicle and the transmission coil is connected to the source of energy only when the pulse signals have ascending or descending fronts.
