    摘要: A coupling apparatus allows anti-phase movements of inertial sensor element frames along parallel axes but substantially prevents in-phase movements of the frames. The coupling apparatus includes a bar coupled between first and second sensor element frames and at least one supporting structure supporting the bar. The at least one structure is coupled to a substrate underlying the frames. The structures allow the bar to rotate at a pivot point when the frames move in anti-phase to one another along substantially parallel axes but substantially prevent in-phase movements of the frames.

    摘要: An inertial sensor includes a cross-quad configuration of four interconnected sensor elements. Each sensor element has a frame and a resonator suspended within the frame. The sensor elements are arranged so that the frames of adjacent sensor elements are allowed to move in anti-phase to one another but are substantially prevented from moving in phase with one another. The sensor elements may be configured in a horizontally coupled arrangement, a vertically coupled arrangement, or a fully coupled arrangement. A pair of sensor elements may be vertically coupled.

    摘要: A capacitive accelerometer. The capacitive accelerometer includes a first fixed electrode and second fixed electrode. The first fixed electrode is separated from the second fixed electrode by a gap. A movable electrode is positioned between the first and second fixed electrodes, the movable electrode being movable between the first and second fixed electrodes. The movable electrode is dimensioned to produce a squeeze damping effect between the movable and fixed electrodes to damp movement of the movable electrode. Circuitry determines the position of the movable electrode in any position across substantially the entire gap between the first and second fixed electrodes.

    摘要: Each of a number of resonator masses is split into two separate lobes or masses joined together by a short flexure. The short flexure allows the separate lobes or masses to rotate slightly as they resonate so as to substantially relieve longitudinal stresses in certain resonator structures.

    摘要: An inertial sensor has an interior filled with a relatively low viscosity fill gas. To that end, the inertial sensor has a housing forming the noted interior, and a movable component within the interior. The inertial sensor also has the noted fill gas within the interior. The fill gas has a viscosity that is less than the viscosity of nitrogen under like conditions. For example, when subjected to the same temperatures and pressures, the fill gas has a viscosity that is less than the viscosity of nitrogen.

    摘要: Quadrature suppression is provided by placing a resonator mass adjacent to a quadrature suppression electrode. The resonator mass is capable of moving substantially parallel to the quadrature suppression electrode and includes a notch formed adjacent to a portion of the quadrature suppression electrode such that a length of resonator mass that is directly adjacent to the quadrature suppression electrode varies as the resonator mass moves relative to the quadrature suppression electrode. The quadrature suppression electrode is capable of producing a lateral force on the resonator mass that varies based on the length of resonator mass that is directly adjacent to the quadrature suppression electrode. Such quadrature suppression can be used in sensors having one or more resonator masses.
