    Abstract: An apparatus and method for flexibly suspending a sensing mechanism between a pair of cover plates, including a sensing mechanism formed in a crystalline silicon substrate; a pair of cover plates formed in crystalline silicon substrates; a first plurality of complementary interfaces in fixed relation between the sensing mechanism and a first one of the cover plates; and a second plurality of complementary interfaces flexibly suspended between the sensing mechanism and a second one of the cover plates with one or more of the flexibly suspended interfaces being a complementary male and female interface.

    Abstract: A net zero isolator having an elongated linear displacement member; and first and second counter rotation members arranged crosswise to the linear displacement member at either end thereof, each of the first and second counter rotation members including a mounting portion spaced apart from an isolated portion on respective first and second sides of the elongated linear displacement member. The elongated linear displacement member and the first and second counter rotation members are structured such that a displacement of the mounting portions along the linear displacement member is balanced by a displacement of the isolated pads. The net zero isolator acts through each of the first and second counter rotation members to generate displacements of the isolated portions that cancel a linear displacement of the mounting portions.

    Abstract: A force rebalance accelerometer includes a proof mass suspended by one or more flexures between stationary mounted upper and lower excitation rings. Pick-off capacitance plates formed on opposing sides of the proof mass form capacitance elements whose capacitance varies in response to displacement of the proof mass to provide a displacement signal. The displacement signal is applied to one or more electromagnets, used to force the proof mass back to a null or at-rest position. The drive current applied to the electromagnets thus represents the force or acceleration applied to the accelerometer. The electromagnets include a magnet and a pole piece which forms a magnetic return path. In order to relieve stresses due to thermal expansion, the magnet is spaced apart from the pole piece to enable the bonding area to be constrained to a minimum which, in turn, reduces the overall stress on the accelerometer.
