Abstract: The invention relates to a method of measuring pressure in which an evacuated capsule (1) containing a resonant element (5) is placed in the fluid whose pressure is to be measured, a vibration characteristic of the element is measured, and the pressure is deduced from said characteristic. A resonant element is used which, during measurement, is to be found in a stress state that is close to buckling. For this purpose, it is possible to use heater means for heating the element and servo-controlled so as to keep the frequency of vibration thereof constant. The resonant element can be made of silicon. The invention is particularly applicable to oil wells.

Abstract: A self-propelled vehicle alternator used both as a generator and as an electric motor for starting the engine of the vehicle. A coil-carrying rotor and a multiphase stator connected to a bridge of diodes and switches for rectifying and controlling the phases cooperate for selective operation as a generator or starting motor. A control unit for the switches recognizes a code signal transmitted by a code transmitter and controls the phases of the stator to cause the alternator to operate as an electric motor and start the engine only if it receives a code signal from the transmitter authorizing starting.

Abstract: A circuit for measuring the duration of a cut-off period in the power supply to an electronic system, for example the control system of a motor vehicle starter, comprises a voltage splitting bridge and a processing unit receiving the output of the splitting bridge. The bridge supply voltage is derived from the power supply to the electronic system, and the bridge has a branch which includes a temperature variable resistor. The processing unit determines the duration of the cut-off period as a function of the value of the output voltage from the splitting bridge at the end of a cut-off period.
