摘要： One example includes a hemispherical resonator gyroscope (HRG). The HRG includes a sensing system comprising a plurality of electrodes arranged in a symmetrical annular arrangement about a sensitive axis and configured to electrostatically force a resonator into a substantially periodic motion based on a plurality of forcer signals applied to the plurality of electrodes. The plurality of electrodes are configured to provide an indication of rotation about a sensitive axis of the HRG. The HRG also includes a controller configured to generate the plurality of forcer signals in a phase-disparate manner to provide the substantially periodic motion in a vibration pattern such that a ratio of the plurality of electrodes and the vibration pattern is a non-integer number, and to measure the rotation about the sensitive axis of the HRG in response to the plurality of forcer signals.

摘要： A vibratory rotation sensor includes a heimspherical resonator, a ring forcer electrode and a plurality of discrete forcer and pick-off electrodes. A vibratory or flexural standing wave pattern is established in the resonator and signals from the pick-off electrodes are combined to produce first (E.sub.c) and second (E.sub.s) signals that represent two independent components of the vibration pattern. A reference phase generator generates timing signal that are used to demodulate E.sub.c and E.sub.s to obtain in-phase and quadrature components thereof. The quadrature components are transformed in a computer to generate nodal and antinodal quadrature signals. The nodal quadrature signal is used as the error signal in a quadrature control loop that keeps both components of the vibration pattern in phase. The antinodal quadrature signal is used as the error signal in a phase-locked loop that keeps the phase of the reference phase generator locked to the phase of the vibration.

摘要： Control for overlapping instruction execution in an arithmetic unit is provided by stepping a sequence of instructions through a plurality of registers connected in cascade and separately decoding each instruction in a register for control of a corresponding stage in one or more data processing paths, each comprising stages through which data being processed is stepped, each stage corresponding to only one register of the control pipeline. The output of the decoder of each instruction register controls the required operations in the corresponding stage of the data pipeline. Automatically indexed indirect addressing is provided by use of pointers for data sources and destinations as required in the execution of every instruction in order to facilitate highly iterative and structured operations on blocks or arrays of data.

摘要： A command guidance weapon system comprising a radar target tracking system, and a weapon with small thrusters mounted on the periphery thereof and with a small beacon transmitter which is tracked by a ground-based fire control system is disclosed. A rapid terminal maneuver is executed by the weapon at an appropriate point in the trajectory of the weapon by sequentially firing the small thrusters. The angular orientation of the weapon is obtained by canting a polarized antenna, located on the rear of the weapon, with respect to the longitudinal axis of the weapon so that the signal transmitted from the weapon to the ground-based fire control system is modulated. The fire control system computes the precise time, based upon the angular orientation of the weapon and the distance between the weapon and the target, to initiate the terminal maneuver by the weapon, and sends a command signal to the weapon.

摘要： An exemplary vibrating mass gyroscope uses a mass disposed for movement along an x-axis and y-axis. First and second electrodes are disposed adjacent surfaces of the mass along an x-axis and y-axis. Circuitry, coupled to the first and second electrodes, provides during a first mode a dither driving voltage on one of the first and second electrodes causing vibrating displacement of the mass along the one of the x-axis and y-axis. The measurement voltage is sensed on the other of the first and second electrodes where the measurement voltage represents a first angular rate value. During a second mode, the circuitry provides a dither driving voltage on the other of the first and second electrodes causing vibrating displacement of the mass along the other of the x-axis and y-axis and measurement voltage is sensed on the one of the first and second electrodes where the measurement voltage represents a second angular rate value. A combiner coupled to the circuitry receives the first and second angular rate values, and generates a resulting angular rate value based on both the first and second angular rate values wherein common bias errors are canceled. The common bias errors cancel because the pickoff sensing axis is coincident with the forcing axis when the same electrode is used for both the forcing and for the pickoff.

摘要： The invention is a method for obtaining linear measures of one or more parameters p.sub.m of a device having one or more input ports i and an output port where m takes on integer values from 1 to M, M being an integer equal to or greater than 1, and i takes on integer values from 1 to I, I being an integer equal to or greater than 1. The device causes one or more input signals G.sub.i (p.sub.m)E.sub.ei (t) fed into one or more input ports to be transformed into an output signal comprising a summation over i of G.sub.i (p.sub.m)H.sub.i (p.sub.m)E.sub.oi (t) at the output port. The function G.sub.i (p.sub.m) is a weighting function associated with the i'th input port, E.sub.ei (t) is an excitation signal associated with the i'th input port, and E.sub.oi (t) is the transformation of the excitation signal E.sub.ei (t) that results from E.sub.ei (t) traversing the path from the input port i to the output port. The signals E.sub.ei (t) and E.sub.oi (t) are both independent of the parameter p.sub.m. The product function G.sub.i (p.sub.m)H.sub.i (p.sub.m) is representable by a power series of order N.sub.im in p.sub.m, the value of N.sub.im depending on a specified accuracy of representation. The method comprising the steps (1) generating one or more linearizing weighting functions G.sub.il (p.sub.m) for which the output signal is a linear measure of the parameter p.sub.m to the specified accuracy of representation, (2) feeding the input signals G.sub.il (p.sub.m)E.sub.ei (t) into the device; and (3) using a component of the output signal as a linear measure of each of the one or more parameters p.sub.m.
