    摘要: Micromachined accelerometer having one or more proof masses (16, 36, 37, 71, 72) mounted on one or more decoupling frames (17, 38, 39) or on a shuttle (73) such that the proof mass(es) can move along a first (y) axis in response to acceleration along the first axis while being constrained against movement along a second (x) axis and for torsional movement about a third (z) axis perpendicular to the first and second axes in response to acceleration along the second axis. Electrodes (26, 53, 54, 78, 79) that move with the proof mass(es) are interleaved with stationary electrodes (27, 56, 57, 81, 82) to form capacitors (A-D) that change in capacitance both in response to movement of the proof mass(es) along the first axis and in response to torsional movement of the proof mass(es) about the third axis, and circuitry (31-34) connected to the electrodes for providing output signals corresponding to acceleration along the first and second axes. The capacitances of two capacitors on each side of the second axis change in the same direction in response to acceleration along the first axis and in opposite directions in response to acceleration along the second axis. Signals from the capacitors that change capacitance in opposite directions both in response to acceleration along the first axis and in response to acceleration along the second axis are differentially combined to provide first and second difference signals, and the difference signals are additively and differentially combined to provide output signals corresponding to acceleration along the first and second axes.

    摘要: Dithering mechanism and method for eliminating the effects of zero-rate bias in a rate sensor or gyroscope. Both continuously moving and indexing embodiments are disclosed. The mechanism includes a first part mounted in a fixed position centered about a dither axis perpendicular to the input axis of the gyroscope, a second part disposed coaxially of the first part and affixed to the sensing element of the gyroscope, and a plurality of piezoelectrically driven quartz flexure beams extending radially between the first and second parts for dithering the second part about the dither axis. In some embodiments, the dithering mechanism is formed separately from and affixed to the sensing element of the gyroscope, and in others it is formed integrally with the sensing element. In the indexing embodiments, radial arms and fixed stops limit movement of the mechanism between two fixed positions, and drive signals and holding potentials are applied alternately to dither the mechanism between the two positions and to hold it alternately in those positions during successive data acquisition periods.

    摘要: A pressure sensor system for measuring the pressure of a corrosive media includes a silicon plate forming a diaphragm and a glass plate or ring bonded to said silicon plate with an opening over the diaphragm. The diaphragm has resistive areas of different orientations to provide first resistive areas which have increased resistance with diaphragm deflection, and other areas which have decreased or little change in resistance with diaphragm deflection. The resistive areas may be formed by doping the silicon plate. The resistive areas have broad doped connectors extending outward to areas beyond the seal between the glass plate or ring, to wire bond areas on the silicon plate. Accordingly, the wire bond pads are not exposed to the corrosive media.
