  • Noise generator using combined outputs of two pseudo-random sequence generators
    Patent number: 5153532
    Abstract: The pseudo-random-bit sequence generators are clocked by separate clock signals of different frequency. The two pseudo-random-bit sequence generator outputs are logically combined by an exclusive-or gate to provide a pseudo-random-bit sequence generator which, when converted to analog signal has improved white noise characteristics.

  • Method of fabricating a readout apparatus for a ring laser gyroscope
    Patent number: 5000571
    Abstract: A gyro readout mask is made from the actual readout interference fringe pattern. A photographic image of the readout interference fringe pattern is made, and the resulting photographic image, or a derivative thereof, is itself used as the mask.

  • Shaded pole electric motor and brake
    Patent number: 3997827
    Abstract: A shaded pole electric motor which utilizes shading coils on the shaded poles is operated to provide a braking action. The shading coils are normally operated to cause the motor to operate either clockwise or counterclockwise. The current flow in the shading coils is used to gate a triac for normal operation. When the triac is not gated, the energizing potential for the motor operates a unidirectional current control circuit to energize the motor winding with half-wave direct current to brake the motor.
