摘要： An electrostatically actuated micromechanical sensor having a guard band electrode for reducing the effect of transients associated with a dielectric substrate of the sensor. A proof mass, responsive to an input, is suspended over the substrate and one or more electrodes are disposed on the substrate in electrostatic communication with the proof mass to sense the input acceleration and/or to torque the proof mass back to a null position. A guard band electrode is disposed over the dielectric substrate in overlapping relationship with the electrodes and maintains the surface of the substrate at a reference potential, thereby shielding the proof mass from transients and enhancing the accuracy of the sensor. A dissolved wafer process for fabricating the micromechanical sensor is described in which the proof mass is defined by a boron doping step. An alternative fabrication technique is also described in which the proof mass is defined by an epitaxial layer.

摘要： A gimballed vibrating wheel gyroscope for detecting rotational rates in inertial space. The gyroscope includes a support oriented in a first plane and a wheel assembly disposed over the support parallel to the first plane. The wheel assembly is adapted for vibrating rotationally at a predetermined frequency in the first plane and is responsive to rotational rates about a coplanar input axis for providing an output torque about a coplanar output axis. The gyroscope also includes a post assembly extending between the support and the wheel assembly for supporting the wheel assembly. The wheel assembly has an inner hub, an outer wheel, and spoke flexures extending between the inner hub and the outer wheel and being stiff along both the input and output axes. A flexure is incorporated in the post assembly between the support and the wheel assembly inner hub and is relatively flexible along the output axis and relatively stiff along the input axis. With this arrangement, the wheel assembly is gimballed on the support. More particularly, the post flexure flexes in response to the output torque; whereas, the spoke flexures allow for the rotational vibration in the first plane. Also provided is a single semiconductor crystal fabrication technique which allows for improved device manufacture.

摘要： A, micromechanical tuning fork gyroscope is fabricated from a unitary silicon substrate utilizing etch stop diffusions and selective anisotropic etching. A silicon structure is suspended over the selectively etched pit. The silicon structure includes at least first and second vibratable structures. Each vibratable structure is energizable to vibrate laterally along an axis normal to the rotation sensitive axis. The lateral vibration of the first and second vibratable structures effects simultaneous vertical movement of at least a portion of the silicon structure upon the occurrence of angular rotation of the gyroscope about the rotation sensitive axis. The vertical movement of the silicon structure is sensed, and a voltage proportional to the movement is generated, for providing an indication of angular rate of rotation detected by the gyroscope.

摘要： A double gimbal micromachined gyroscopic transducer is provided in a substrate having a pit extending downwardly from a top surface of the substrate. A gyroscopic transducer element suspended above the pit comprises an outer sense gimbal plate integral with the substrate, coupled to the substrate by a pair of flexible elements attached to opposite ends of the plate. The flexible elements are axially aligned to permit oscillatory motion about a sense axis passing through the flexible elements. The gyroscopic transducer further includes an inner drive gimbal plate integral with and interior to the sense gimbal plate. The drive gimbal plate is coupled to the sense gimbal plate by a second pair of flexible elements along an axis orthogonal to the first pair of flexible elements. The drive gimbal plate also includes a balanced mass generally centrally located on the drive gimbal plate. Also included are drive and sense electronics, for energizing the drive gimbal plate to oscillate about the drive axis, and for sensing any movement of the sense gimbal plate indicative of an angular rate about an input axis. The sense electronics includes a sense electrode disposed so as not to be in close proximity to and interfere with free oscillatory motion of the drive gimbal plate.

摘要： This invention relates to the fabrication of planar inductive components whereby the design in cross-section describes a conductor surrounded by magnetic material along the length of the conductor; an electrical insulator is placed between the conductor and the magnetic material. Cases also apply where more than one independent conductor is used. The planar form allows integration of inductive components with integrated circuits. These inductive components can be embedded in other materials. They can also be fabricated directly onto parts.

摘要： A rate gyroscope and accelerometer multisensor, and a process for fabricating the device. The device has an inner magnetically-suspended spinning wheel rotor, with outer stator portions adjacent both faces of the rotor. In one embodiment of the process, three substrates of magnetic material are provided. A first substrate is used to form the portion comprising the rotor. The other two substrates are used to form the outer stator portions. A series of spaced concentric grooves are formed in the central region of both faces of the first substrate. Outside of the grooves on both faces of the first substrate a series of spaced spiral grooves are formed. A hole is placed at the center of the spiral grooves, and filled with magnetic material. A conductor is then deposited into the spiral grooves. A central wheel is formed, the wheel carrying the spaced concentric grooves and defining along its edge a series of spaced teeth. A series of spaced serpentine grooves are formed on one active face of each of the other two substrates. On the same face, a series of generally radial grooves are formed. A conductor is then deposited into the serpentine grooves, and a magnetic material is deposited into the generally radial grooves. The active faces of the two outer substrates are then bonded against the first substrate such that the outer end of each magnetic path overlays a filled hole in the first substrate, to create the stator of an axial air gap reluctance motor.
