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.

Abstract: Disclosed is a housing and support plate assembly for use with a dithered ring laser gyroscope which attenuates thermal and structural changes due to a varying environment. A dither mechanism is structurally supported between a housing and a support plate in a manner which serves to attenuate cross-axis movement and input axis tilting of the gyro assembly, and torsional stress.

Abstract: A discriminant apparatus for laser angular rate sensors which provides an output signal related to a selected weighted vectorial sum of the coupling of energy between counterpropagating waves traveling about a closed-loop path. The discriminant apparatus is utilized in a closed-loop control system for minimizing the lock-in rate of the sensor and/or maintaining and selecting scale factor linearity.
