    Abstract: A transducer assembly includes first and second stators which are axially aligned with, and bear upon opposite sides of a proof mass. The stators and proof mass are clamped together by means of a sleeve having a side portion with spaced apart upper and lower flanges extending therefrom. The flanges bear against receiving surfaces on the stators with the sleeve under elastic deformation such that a compression force tending to reduce the spacing between the flanges is transmitted to the stators and proof mass as a controlled compressive axial preload.

    Abstract: A method and apparatus for enclosing a sensing device, such as an accelerometer, for reducing outside forces and strains on the sensing device. The cover includes two parts that bond to each other thereby forming a clamshell-type cover. The sensing device can float within the cover, is bonded to bonding points on one of the cover parts or is held in place by a pressure fit of the two cover parts on the sensing device.

    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. In particular, a bead of relatively noncompliant epoxy is used for bonding the excitation ring and pole piece to the magnet. In order to further reduce thermal stresses, a ring of relatively compliant epoxy is disposed concentric to the noncompliant epoxy.

    Abstract translation: 力重平衡加速度计包括通过固定安装的上和下激励环之间的一个或多个挠曲物悬挂的检验质量块。 拾取电容板形成在检测质量体的相对侧上的电容元件，其电容响应于证明块的位移而变化以提供位移信号。 位移信号被施加到一个或多个电磁体，用于迫使质量块回到空或静止位置。 因此，施加到电磁体的驱动电流表示施加到加速度计的力或加速度。 电磁铁包括形成磁返回路径的磁铁和极片。 为了减轻由于热膨胀引起的应力，磁体与极片间隔开，使得接合面积被限制在最小限度，这又降低了加速度计上的整体应力。 特别地，使用相对不符合环氧树脂的焊道将激励环和极片接合到磁体。 为了进一步降低热应力，相对顺应性的环氧树脂环与不合适的环氧树脂同心地设置。

    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.
