    Abstract: A vibrating gyroscope includes a proof mass (1); a spring suspension system (5, 6, 7, 8; 9) for suspending the proof mass; an electrical drive mechanism for vibrating the proof mass along a drive axis (x); and electrodes (2, 3) for building together with at least a part of the proof mass (1) a capacitance system for detecting moves of the proof mass along a sense axis (z) perpendicular to the drive axis. The gyroscope is arranged so that quadrature forces generate displacements of the proof mass without substantially displacing the neutral point (10) of the proof mass along the sense axis (z). This may be achieved by tilting the proof mass while keeping its neutral point at a constant position along the sense axis, or by applying a constant electrostatic force.

    Abstract: Microelectromechanical system (MEMS) comprising: an active part (5) comprising an electromechanical device (28), at least one base (6) for fastening said microsystem on a support (8), at least one fastener (21, 21′) fastening said active part (5) to said at least one base (6) and allowing a displacement of said active part (5) relatively to said at least one base (6) along an axis (Z) more or less perpendicular to the plane of said support (8) when said microsystem is fastened onto said support (8), bumper elements (27, 27′, 37′) for limiting the amplitude of the displacements of said active part (5) relatively to said at least one base (6) along said perpendicular axis (Z). The active part (5) being capable of moving relatively to the base (6) to which it is fastened, it is isolated from any mechanical constraint that could be sustained by the base (6), in particular torsion or flexion due to it being fastened onto a support (8). On the other hand, since the movements of the active part (5) are limited by the bumper elements (27, 37, 27′, 37′), it can be guaranteed thanks to the invention that the fastener or fasteners (21, 21′) will not be stretched beyond their elasticity range, thus avoiding their irreversible deformation and/or their rupture.

    Abstract: A differential pressure transducer has a measurement chamber which is divided by a membrane into first and second measurement spaces which can be exposed to first and second pressures whereby differential pressure causes deflection of the membrane from its neutral position. A deflection sensor measures the deflection of the membrane and produces a deflection signal. An electromagnet arrangement produces a magnetic force which compensates for the deflection force which is caused by the differential pressure. The coil current for producing the magnetic compensation force represents a measure of the differential pressure.
