    Abstract: PCT No. PCT/FR96/01968 Sec. 371 Date Jul. 30, 1998 Sec. 102(e) Date Jul. 30, 1998 PCT Filed Dec. 10, 1996 PCT Pub. No. WO97/22010 PCT Pub. Date Jun. 19, 1997An accelerometer based on monocrystalline silicon. A moving mass is connected to a fixed frame by suspension arms. The sensor is produced in the stack of two silicon wafers in which stop and counter-stop functions are produced so as to limit the amplitude of the movements of the moving mass.

    Abstract: L'invention concerne un accéléromètre électromagnétique comportant une partie sensible en silicium avec une masse mobile (2) reliée à un cadre périphérique (3) via des bras de suspension (80,81). La partie sensible en silicium est solidaire d'un moteur (1) à raideur dite négative comprenant une enceinte polaire (12) fixe liée au cadre périphérique, un aimant (5), une bobine (6) et une partie polaire mobile (14) insérée dans l'enceinte (12), ladite partie polaire (14) étant solidaire de la masse mobile (2). Application: géophone.

    Abstract: PCT No. PCT/FR96/01969 Sec. 371 Date May 4, 1999 Sec. 102(e) Date Apr. 5, 1999 PCT Filed Dec. 10, 1996 PCT Pub. No. WO97/22011 PCT Pub. Date Jun. 19, 1997An electromagnetic accelerometer includes a peripheral frame, a mass suspended from the peripheral frame, a plurality of strain gauges configured to detect displacement of the mass, and a magnetic motor. The magnetic motor includes a first pole piece defining a chamber, a second pole piece positioned in the chamber and coupled to the mass, a permanent magnet coupled to the first pole piece, and a coil coupled to the first pole piece. The permanent magnet and the coil surround at least a portion of the second pole piece.
