摘要： Inertial Measurement Units based on integrated designs to reduce alignment and assembly costs. Integration also leads to performance improvement, increased miniaturization and simplification as well as reduced cost. Also disclosed are gyroscopes and accelerometers that are identical, yet by their mechanization, can be made to act as separate sensors. Miniaturization and simplification is improved by combining instruments that can share a common member. Savings in space and complexity are also possible in the electronics when elements are shared.

摘要： A human-portable MEMS azimuth sensing unit and method that determines the azimuth of a target. There is a spinning support structure, with at least a gyroscope carried by the support structure. The gyroscope has an input axis and an output signal. There is an angle resolver that measures the spin angle of the support structure relative to a reference direction and that has an output signal. Circuitry determines the target azimuth based on the phase difference between the output signals of the gyroscope and the angle resolver. The phase difference can be based on the time between zero crossings of the sinusoidal gyro and angle resolver signals. An accelerometer can also be carried by the support structure, in which case its output can be used to level the unit.

摘要： A system and method for damping undesired motion of a suspended structure that is connected by one or more flexures that have an elastic limit to a fixed structure in a MEMS sensor, wherein the undesired motion is caused by a high G acceleration pulse. At one or more of before and during a high G acceleration pulse that could move the suspended structure beyond the elastic limit of a flexure, the system actively generates an attractive force that acts to counteract motion of the suspended structure caused by the high G acceleration pulse, so as to maintain motion of the suspended structure within the elastic limit of the flexure.

摘要： A single-mode optical-fiber directional coupler including at least two optical fibers each having a core surrounded by a cladding material and having a region of reduced cladding diameter contiguous with a reduced-cladding diameter region of the other fiber throughout the length of an optical interaction area. Each reduced-cladding-diameter region is bounded on each end by a tapered region which gradually increases in diameter as it extends away from the reduced-cladding-diameter region toward a full-diameter region of each fiber. There is also a substrate and means for securing the reduced-cladding-diameter region to the substrate, means for supporting the fibers in their full-diameter region beyond each end of the optical interaction area, means for fastening the support means to the substrate and a medium surrounding the reduced-diameter regions and having an index of refraction similar to that of the cladding material. This invention also features a method of making such a directional coupler involving temperature gradients in temperature sensitive etchant placed along portions of the cladding areas of at least two optical fibers.

摘要： A system and method for separating bias instability of MEMS inertial instruments such as gyroscopes or accelerometers from the instrument signal, in which the inertial measurement instrument has an input axis and an output signal, and the bias instability has a frequency. The instrument is oscillated about an oscillation axis that is orthogonal to the input axis, at a frequency that is greater than the bias instability frequency. The instrument output signal is detected, and demodulated with a phase-sensitive detection method referenced to the instrument rotation.
