    摘要: A sensor for measuring acceleration in three mutually orthogonal axes, X, Y and Z is disclosed. The sensor comprises a sensor subassembly. The sensor subassembly further comprises a base which is substantially parallel to the X-Y sensing plane; a proof mass disposed in the X-Y sensing plane and constrained to move substantially in the X, Y, and Z, about by at least one linkage and is responsive to accelerations in the X, Y and Z directions. The sensor includes at least one paddle disposed in the sensing plane; and at least one pivot on the linkage. Finally, the sensor includes at least one electrode at the base plate and at least one transducer for each sensing direction of the sensor subassembly responsive to the acceleration.

    摘要: The present invention is directed towards apparatuses for rotating a gimbaled platform with rotatable actuators. Gimbal springs comprised of component springs with compliant axes that intersect at a nonzero angle are coupled to the gimbaled platform. Preferably, the compliant axes of the component springs are oriented at an approximately 45 degree angle relative to the actuator rotation axes. Wraparound lever arms coupling the rotatable actuators with the gimbal springs serve to increase the leverage ratio, thereby permitting greater platform rotation for a given actuator rotation.

    摘要: Optical fibers are inserted and bonded in a two dimensional array of feedthroughs provided by an insert having a top plate, a bottom plate and a sandwiched spacer plate. Top and bottom plate feature funnel shaped hole sections that capture the approaching fiber end during its insertion. The funnel sections terminate in narrow hole sections that tightly hold the inserted fiber ends. Having top and bottom plate spaced apart provides for high angular precision of the bonded fiber ends with minimal fabrication effort of the insert. Optical fibers may be combined in linear arrays and simultaneously inserted significantly reducing assembly efforts. The insert is attached to a fiber housing and hermetically sealed within an external housing, which features a glass plate to provide beam propagation to and from the fiber ends. An optical gel fills the gap between the insert's output face and the glass plate.

    摘要: In a method and system in accordance with the present invention, solder balls are added on top of vertically integrated MEMS with CMOS by using wafer scale fabrication compatible with existing chip scale packaging capabilities. In the present invention, both the MEMS and the CMOS dies are fabricated in equal dimensions. On the MEMS level, silicon islands are defined by DRIE etching to be bonded on top of CMOS pads. These conducting silicon islands later provide electrical connections between the CMOS pads and the conducting traces that lead to solder balls on top.

    摘要: A system and method in accordance with the present invention provides for a low cost, bulk micromachined accelerometer integrated with electronics. The accelerometer can also be integrated with rate sensors that operate in a vacuum environment. The quality factor of the resonances is suppressed by adding dampers. Acceleration sensing in each axis is achieved by separate structures where the motion of the proof mass affects the value of sense capacitors differentially. Two structures are used per axis to enable full bridge measurements to further reduce the mechanical noise, immunity to power supply changes and cross axis coupling. To reduce the sensitivity to packaging and temperature changes, each mechanical structure is anchored to a single anchor pillar bonded to the top cover.

    摘要: A wafer-scale fabrication method for providing MEMS assemblies having a MEMS subassembly sandwiched between and bonded to a cap and a base is provided. The MEMS subassembly includes at least one MEMS device element flexibly connected to the MEMS assembly. The vertical separation between the MEMS device element and an electrode on the base is lithographically defined. Precise control of this critical vertical gap dimension is thereby provided. Fabrication cost is greatly reduced by wafer scale integration.

    摘要: An angular velocity sensor has two masses which are laterally disposed in an X-Y plane and indirectly connected to a frame. The two masses are linked together by a linkage such that they necessarily move in opposite directions along Z. Angular velocity of the sensor about the Y axis can be sensed by driving the two masses into Z-directed antiphase oscillation and measuring the angular oscillation amplitude thereby imparted to the frame. In a preferred embodiment, the angular velocity sensor is fabricated from a bulk MEMS gyroscope wafer, a cap wafer and a reference wafer. In a further preferred embodiment, this assembly of wafers provides a hermetic barrier between the masses and an ambient environment.
