摘要： A shear-mode quartz resonator designed to mechanically oscillate at a predetermined frequency and electronic circuits for inhibiting oscillation of the shear-mode quartz resonator in response to externally applied mechanical forces which otherwise induce mechanical vibration of the shear-mode quartz resonator at frequencies significantly less than the predetermined frequency. The shear-mode quartz resonator includes a cantilevered quartz beam having relatively large metallic electrodes attached on opposite sides thereof, the relatively large metallic electrodes, in use, being coupled to an external oscillator circuit. The beam also has relatively smaller sense and rebalance electrodes attached on the same opposite sides of said quartz beam as said relatively large metallic electrodes. The relatively smaller sense and rebalance electrodes being coupled, in use, with said electronic circuits for inhibiting oscillation of the shear-mode quartz resonator in response to externally applied mechanical forces.

摘要： A magnetometer has a resonating structure which is naturally resonant in at least first and second resonant modes, a resonant frequency of the second mode being at least an order of magnitude greater than a resonant frequency of the first mode, the resonating structure having two sense electrodes disposed on opposing major surfaces of the resonating structure and having a conductive path formed as a loop, the loop being disposed near or at edges of the resonating structure and the two sense electrodes being formed inwardly of the edges of the resonating structure and also inwardly of said loop. First and second oscillators are provided, the first oscillator being coupled to the loop for applying an oscillating current to the loop, the oscillating current having a frequency essentially equal to the resonant frequency of the first mode of the resonating structure, the second oscillator being coupled to said sense electrodes, the second oscillator oscillating with a fundamental frequency corresponding to the resonant frequency of the second mode of the resonating structure, the second oscillator also producing sidebands indicative of the magnetometer sensing an external magnetic field.

摘要： An apparatus for driving and sensing motion in a gyroscope including a dielectric mass, an anchor, a spring coupled between the anchor and the dielectric mass, a substrate adjacent the dielectric mass, an insulator layer on the substrate, and a first electrode and a second electrode on the insulator layer. When an alternating current voltage is applied between the first and second electrodes, an electric field gradient is generated in the dielectric mass and causes the dielectric mass to move relative to the anchor. When the dielectric mass has motion relative to the anchor and a voltage is applied between the first and second electrodes, the movement of the dielectric mass generates a current at the first and second electrodes proportional to the motion.
