    摘要: A micromachined inertial sensor with a single proof-mass for measuring 6-degree-of-motions. The single proof-mass includes a frame, an x-axis proof mass section attached to the frame by a first flexure, and a y-axis proof mass section attached to the frame by a second flexure. The single proof-mass is formed in a micromachined structural layer and is adapted to measure angular rates about three axes with a single drive motion and linear accelerations about the three axes.

    摘要: Angular rate sensor for detecting rotation about first and second mutually perpendicular axes which has first and second masses coupled together for torsional drive mode oscillation of equal amplitude and opposite phase about third axes which are perpendicular to the first and second axes. The first mass is mounted for oscillation about the second axis in response to Coriolis forces produced by rotation about the first axis, and the second mass is mounted for oscillation about the first axis in response to Coriolis forces produced by rotation about the second axis. In some disclosed embodiments, the rate sensor also includes a pair of accelerometer masses which are connected together for torsional movement of equal amplitude and opposite phase about axes parallel to the third axes in response to acceleration along the second axis and for torsional movement of equal amplitude and opposite phase about axes parallel to the second axis in response to acceleration along the third axes.

    摘要: A MEMS device which utilizes a capacitive sensor or actuator is enhancement by initially fabricating the capacitive assembly which comprises the sensor or actuator as two sets of interdigitated fingers in a noninterdigitated configuration. One of the two sets of fingers is coupled to a movable stage. The stage is moved from an initial position to a post-release position in which the two sets of interdigitated fingers are interdigitated with each other. The stage is carried by two pairs flexures which maintain the stability of motion of the stage and when in the post-release position provide stiffness which prevents deflection of the set of fingers coupled to the stage. The stage and hence the assembled sets of fingers are then locked into the post-release position.
