    摘要: The invention concerns a system for measuring at least one physical parameter in a site of a patient's body accessible by a medical probe, comprising a medical probe (1) consisting of a rod (2) equipped with means sensing said parameter and means for delivering an electric signal representing said parameter, and collected by the sensor, to a data processing device external to the patient. The sensor is contained in an electronic measuring module (41, 42) which also includes other elements constituted by electronic means associated with the sensor for supplying a measurement signal, means for remote transmission of the measurement signal, means for powering said elements.

    摘要: A resonator micro-electronic inertial sensor, preferably a micro-electromechanical system (MEMS) sensor (e.g. a gyro), for detecting linear accelerations and rotation rates in more than one axis comprises: €¢ a proof-mass system (21.1, ..., 21.4) flexibly suspended above a substrate for performing a rotational in-plane vibration about a central axis (24,) €¢ a drive electrode system (D1, ..., D4) for driving the proof-mass system (21.1, ..., 21.4) to perform said rotational in-plane vibration, €¢ and a sensing electrode system (S1, ..., S8) connected to the proof-mass system (21.1, ..., 21.4) for detecting linear accelerations or rotation rates in more than one axis. Said proof-mass system (21.1, ..., 21.4) has more than two proof-mass elements flexibly coupled (25.1a, 25.1 b) to each other. Each proof-mass element (21.1, 21.2) is directly and flexibly connected (23.1, 25.1a, 25.1 b) to an anchor structure (22) on the substrate (32). The proof-mass elements (21.1, ..., 21.4) are preferably arranged in a ring-shaped configuration between an inner and an outer radius (R1, R2) with respect to the central axis (24).

    摘要: The invention relates to a mechanical oscillator equipped with a bar (11), said bar (11) including a first silicon layer (Cs1) having a crystal lattice extending in a first direction (Ds1) of a plane, a thermally compensating layer (Co1) formed from a material having a Young's modulus of thermal coefficient of opposite sign to that of silicon, and a second silicon layer (Cs2) having a crystal lattice extending in a second direction (Ds2) of the plane, the first and second directions (Ds1, Ds2) being shifted by an angle of 45° in the plane of the layers, and the thermally compensating layer (Co1) extending between the first and second silicon layers (Cs1, Cs2).
