    Abstract: According to some aspects, there is provided a microelectromechanical systems (MEMS) device wherein one or more components of the MEMS device exhibit attenuated motion relative to one or more other moving components. The MEMS device may comprise a substrate; a proof mass coupled to the substrate and configured to move along a resonator axis; and a first shuttle coupled to the proof mass and comprising one of a drive structure configured to drive the proof mass along the resonator axis or a sense structure configured to move along a second axis substantially perpendicular to the resonator axis in response to motion of the proof mass along the resonator axis, wherein displacement of at least a first portion of the proof mass is attenuated relative to displacement of the first shuttle and/or a second portion of the proof mass.

    Abstract: Novel structural features applicable to a variety of inertial sensors. A composite ring composed of concentric subrings is supported by a compliant support structure suspending the composite ring relative to a substrate. The compliant support structure may either be interior or exterior to the composite ring. The compliant support may be composed of multiple substantially concentric rings coupled to neighboring rings by transverse members regularly spaced at intervals that vary with radius relative to a central axis of symmetry. Subrings making up the composite ring may vary in width so as to provide larger displacement amplitudes at intermediate radii, for example. In other embodiments, electrodes are arranged to reduce sensitivity to vibration and temperature, and shock stops are provided to preclude shorting in response to shocks.

    Abstract: Micromachined inertial devices are presented having multiple linearly-moving masses coupled together by couplers that move in a linear fashion when the coupled masses exhibit anti-phase motion. The couplers move in opposite directions of each other, such that one coupler on one side of the movable masses moves in a first linear direction and another coupler on the opposite side of the movable masses moves in a second linear direction opposite the first linear direction. The couplers ensure proper anti-phase motion of the masses.
