    摘要: An apparatus for measuring the rate of rotation and linear acceleration of a moving body in two perpendicular axis (X and Y). The rate of rotation is determined by measuring the force resulting from the Coriolus effect and the linear acceleration is determined by measuring the resulting force in the axis of acceleration. The apparatus includes an integral flexing unit which during rest extends in the Z axis, having a flexure zone with two degrees of flexing freedom. A proof mass is resiliently mounted on the flexing unit remote from the flexure zone with one degree of oscillation in parallel to the Z axis. The proof mass is caused to oscillate at constant amplitude by suitable electric means whereby, upon rotation of the body or linear acceleration thereof, the flexure unit oscillates by periodic bending of the flexure zone and the extent of flexure which is proportionate to the rate of rotation and/or linear acceleration, is determined by suitable electro optical means. The apparatus further includes processor means for calculating the angular velocity components about the axis of rotation and the linear acceleration components along the axis of acceleration from the extent of flexure.

    摘要: A permanent magnet two degree of freedom gyroscope (10) utilizing a single rotor (12) having a trapezoidal shaped pattern formed thereon. The trapezoidal pattern consists of a reflective segment (11) and a non reflective segment (13). Two optical sensors (14, 18) fixed with respect to the stator, obtain angular displacement information about the two axes perpendicular to the spin axis, rotor pole location information, which is used for commutation, and, rotor speed information. The present invention deals with an apparatus and method for starting, running and torquing the two degree of freedom permanent magnet gyro motor (10) based on position and displacement information obtained from the two optical detectors (14, 18). The angular displacement information is obtained by sensing differences in the optical pattern as the rotor (12) spins and is displaced about cross-axes, perpendicular to the spin axis.

    摘要: An inertial sensor arrangement comprises two electrically restrained gyros with three mutually orthogonal input axes. After A/D-conversion pick-off signals are supplied to a digital computer which forms part of the restraining loop of the gyros and provides digital output signals. The output signals are applied to a D/A-converter which supplies corresponding currents to the torquer of the gyros. Thereby integrating quantization errors are avoided. The cross-coupling behavior and gyro errors can be compensated in the computer. The inertial sensor arrangement can be measured as an entirety. The gyro parameters measured thereby are memorized in an EEPROM and are taken into account in the computer.

    摘要: The disclosure relates to a gyroscope in which an electric signal corresponding to an angle (-.alpha., +.alpha.) between the rotor of the gyroscope and the frame of the rotor is generated. The rotor is provided with one or more permanent magnets. An element of magnetic material is disposed in the frame of the rotor so that the latter may move in relation to the element during its rotation. The element may be passed by the magnetic fields of the permanent magnets during rotation of the rotor so that magnetic flux changes occur in the element. The element is arranged such that the flux changes are dependent upon the above-mentioned angle and the flux changes are sensed by an electric induction winding which generates the electric signal.

    摘要: In a multisensor assembly for detecting angular rates and linear accelerations, a diamond-shaped piezoelectric crystal beam is used to restrain a gyroscopic element to a base of the multisensor assembly. The diamond-shaped piezoelectric crystal is fixed to both the gyroscopic element and the base of the assembly by means of wires in an orientation orthogonal to the hinge axis and the spin axis of the assembly. This allows the piezoelectric crystal to experience only one degree of freedom. To improve the accuracy of the output electrical signal, oblong electrodes are placed on opposite surfaces of the piezoelectric crystal beam.
