    Abstract: An angular rate sensor provides a digital delta theta output signal. A drive member is formed of a single, silicon wafer having a pair of oppositely-facing planar surfaces. The drive member includes a frame and a drive member central portion connected to the frame and arranged to have rotational compliance between the frame and the central portion about an axis perpendicular to the planar surfaces of the silicon wafer. Drive signals are applied to a plurality of electrodes on the central portion to cause rotational oscillation of the drive member central portion about a drive axis perpendicular to the planar surfaces of the silicon wafer. A silicon sensing member is connected to the drive member. The sensing member has a central support member connected to the drive member central portion such that rotational oscillations of the drive member central portion are transmitted to the sensing member central portion. A sensing portion is connected to the sensing member central support member to allow the sensing portion to oscillate about the drive axis and to allow an input rotation rate about an axis perpendicular to the drive axis to produce out-of-plane oscillations of the sensing portions. Signal processing apparatus is connected to the sensing portion for producing a signal indicative of the input rotational rate as a function of the amplitude of the out-of-plane oscillations of the sensing portion.

    Abstract: A three-dimensional acceleration sensor capable of detecting a small acceleration value and even an acceleration value amounting up to 100G occurring in the event of a collision comprises a diaphragm for linking a frame and a massive part and diaphragms and beams for linking the massive part and a central part. These elements are formed by working a single crystalline silicon plate. Gaps between the massive part and opposing electrodes are changed by acceleration applied to the massive part. A circuit connected to terminals detects the changes in gaps as changes in capacitances and determines direction and level of the applied acceleration.

    Abstract: A resonant bridge two-axis microaccelerometer is disclosed comprising polysilicon resonant bridges orthogonally attached to a silicon proof mass, such that the silicon proof mass is suspended by the resonant bridges. Acceleration in the plane of the substrate causes differential axial loads on the opposing microbridges in each pair, thereby shifting their resonant frequencies. The acceleration component aligned with a pair is measured by the difference in resonant frequencies.

    Abstract: A resonant bridge microaccelerometer is formed using patterned Silicon-on-Insulator (SOI) material. A buried layer is formed in the silicon substrate using preferably oxygen ion implanting techniques. A predetermined proof mass is subsequently formed by selective deposition of an appropriate material on an epitaxially grown layer of silicon generally over the buried layer. The buried layer is subsequently removed by a hydrofluoric acid etch, thereby forming a gap generally everywhere therebetween the proof mass and the supporting silicon substrate, and delineating the resonant microbridges within the microaccelerometer.
