Latest Patents

One of Loper's latest patents is the vibratory rotation sensor. This device includes a heimspherical resonator, a ring forcer electrode, and multiple 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 signals that are used to demodulate E.sub.c and E.sub.s to obtain in-phase and quadrature components. The quadrature components are transformed in a computer to generate nodal and antinodal quadrature signals. The nodal quadrature signal serves as the error signal in a quadrature control loop that maintains both components of the vibration pattern in phase. The antinodal quadrature signal is utilized 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.

Another significant patent is the single-axis crystal constrained temperature compensated digital accelerometer. This device employs a pair of SC-cut crystals that respond differentially to acceleration inputs. Each crystal exhibits a highly temperature-sensitive resonant mode and a relatively temperature-insensitive resonant mode. Both modes are excited simultaneously by an oscillator. The difference frequency data between respective modes of each crystal, as well as the difference frequency data between the two modes of one of the crystals, is processed to obtain a temperature-compensated value of acceleration.
