  • Patent number: 6407526
    Abstract: Some automobiles have mechanisms for adjusting the height of accelerator and brake pedals, and any clutch pedal, so that drivers large and small can adjust the pedals to the best height. All pedals are adjusted by a single reversible electric motor having a shaft connected directly or by a flexible shaft to the adjusting mechanisms. If any fault develops in any mechanism, the pedals may not be adjusted to the same height, which is hazardous to the driver. A safety switching system detects any serious misalignment of the pedals and de-energizes the motor. The system comprises separate switches which are operable by adjustment of the pedals, and are electrically connected in series with the power supply circuit for the motor. When the pedals are aligned, the bridging contactors of the switches are aligned and are effective to maintain the electrical continuity of the motor circuit. Each contactor has three contact sliders which successively engage staggered tabs on contact strips for the respective pedals.

    Abstract: A two-axis rate gyroscope of the captured type is provided having a cylindrical rotor with one or more inwardly projecting flanges. The rotor is disposed within a sealed toroidal cavity in a rotor housing and the interior of the cavity is evacuated to a "hard" vacuum. An electrostatic suspension system restrains the rotor from translatory movement along the gyroscope spin axis and two axes perpendicular thereto so that a virtually frictionless spin bearing is provided for the rotor. The suspension system functions to prevent relative angular rotation between the rotor and the rotor housing about two precession axes. The rotor housing is mounted on a flexure joint which prevents translatory movement of the housing along three orthogonal axes but permits rotational movement of the housing about the two precession axes.
