Abstract: A ring laser gyro system having at least one fixed mirror, and two movable mirror assemblies, for causing a pair of laser beams to counter-rotate therebetween, including amplitude control circuits and a phase control circuit for causing the movable mirror assemblies to sinusoidally oscillate at the same amplitude and frequency, but 180.degree. out of a phase with one-another, to substantially eliminate lock-in.

Abstract: A system for measuring the position of a vibrating object relative to a reference point, such as the block of a ring-laser gyroscope relative to its case, uses a continuous velocity sensor that is noisy and subject to drift and a precise position crossing detector. A mixer-filter combines the data from the two sensors so that the capability of the velocity sensor to provide a continuous reading of position is exploited to interpolate data between the instants that the position crossing detector indicates that the object position crosses through zero. The mixer-filter is implemented in the form of an extended Kalman filter which operates upon the inputs to provide an optimum estimate of the position of the vibrating object.

Abstract: A device to measure the mass-flow rate of a fluid from the Coriolis force resulting from the flow of the fluid through the device during oscillation. The device comprises four U-shaped tubes wherein the phase and direction of flow in these tubes are arranged so as to cancel the errors due to motion of the instrument base.

Abstract: The present invention operates on the principle that the velocity vector of a land-vehicle is along the longitudinal axis of the vehicle. The invention uses an odometer in conjunction with a set of three single axis rate gyros strapped down to the vehicle to provide a land vehicle navigation system. The single axis rate gyros are rigidly mounted to the body with input axes parallel to a set of reference axes in the vehicle. By means of these gyros it is possible to infer the heading of the vehicle and thereby achieve a navigation accuracy comparable to the accuracy that the same gyros would provide in a gimballed system, but without the necessity for the set of gimbals.

Abstract: A system for cancelling lock-in in a spring suspended ring laser gyroscope by dithering it at a rate which is a function of measured optical phase and dither rate.

Abstract: A system for offsetting lock-in in a spring-suspended ring laser gyroscope by dithering it by means of a torquer whose input is controlled by the sum of an analog positive-feedback signal for cancelling out losses due to damping and a piecewise-constant signal for adjusting the effective dither angular velocity phase in each cycle.

Abstract: An electrical circuit interposed between the pickoffs and torquers of a two-axis gyroscope. The circuit output controls the torquers. When the pickoff signals vary at the nutation frequency, the angular accelerations produced by the torquers damp the nutation. No angular accelerations are produced when the pickoff signals are not varying and only negligible angular accelerations are produced when the pickoff signals vary at a frequency other than the nutation frequency.

Abstract: In a ring laser gyroscope the residual "lock-in" which normally remains with an open loop dither system is overcome through the use of a dynamic feedback system between the output of the ring laser gyro and the dither rate input.

Abstract: An ellipticity control system for controlling the elliptical deviation of the vibratory element of a displacement sensor. The apparatus incorporates a plurality of drive electrodes, at least six in number, mounted concentrically along the longitudinal axis of the elongated vibratory element. Each drive electrode is formed in pairs oriented along separate axes. A pair of X-axis pickoffs and a pair of Y-axis pickoffs axially spaced from the drive electrodes are also mounted concentrically of the vibratory element to sense the deviation of the vibratory element from null and to provide control signals by way of circuit means to the drive electrodes.

Abstract: Stable reference gyroscopic apparatus is provided in the form of an angular displacement sensor which employs an end-supported vibratory rod or wire, instead of the commonly used rotatable element. The apparatus of the invention incorporates an improved means for maintaining the vibrational amplitude of the center of the vibratory element constant, and electronic circuit means for causing the orbit of center of the vibratory element to remain in a straight line, both means being effective to eliminate the major sources of potential drift in the sensor.

Abstract: A precision accelerometer is provided which is capable of measuring linear accelerations along three axes. The accelerometer incorporates a self-charging radioactive particle as the inertial acceleration sensing mass. The particle is contained in an evacuated cubical chamber, and the position of the particle within the chamber is established by the differential between the mean number of emitted charged particles detected at the opposite walls of the chamber, whenever the particle moves from a central position within the chamber. The accelerometer includes an electronic control system which generates feedback signals that tend to maintain the particle centered within the chamber in the presence of accelerations, and at the same time to provide electrical outputs which are measurements of the accelerations along the three coordinate axes.
