    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: 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.
