摘要： The present disclosure relates to an inertia measurement module for an unmanned aircraft, which comprises a housing assembly, a sensing assembly and a vibration damper. The vibration damper comprises a first vibration-attenuation cushion; and the sensing assembly comprises a first circuit board, a second circuit board and a flexible signal line for connecting the first circuit board and the second circuit board. An inertia sensor is fixed on the second circuit board, and the first circuit board is fixed on the housing assembly. The inertia measurement module further comprises a weight block, and the second circuit board, the weight block, the first vibration-attenuation cushion and the first circuit board are bonded together. The present disclosure greatly reduces the influence of the operational vibration frequency of the unmanned aircraft on the inertia sensor and improves the measurement stability of the inertia sensor.

摘要： An apparatus (36) includes a motion amplification structure (52), an actuator (54), and a sense electrode (50) in proximity to the structure (52). The actuator (54) induces an axial force (88) upon the structure (52), which causes a relatively large amount of in-plane motion (108) in one or more beams (58, 60) of the structure (52). When sidewalls (98) of the beams (58, 60) exhibit a skew angle (28), the in-plane motion (108) of the beams (58, 60) produces out-of-plane motion (110) of a paddle element (62) connected to the end of the beams (58, 60). The skew angle (28), which results from an etch process, defines a degree to which the sidewalls (98) of beams (58, 60) are offset or tilted from their design orientation. The out-of-plane motion (110) of element (62) is sensed at the electrode (50), and is utilized to determine an estimated skew angle (126).

摘要： The present invention provides a composite vibrator that can maintain high sensitivity even when miniaturized. The composite vibrator includes tuning bar vibrators having the same length and support members for supporting the tuning bar vibrators. The tuning bar vibrators are arranged in a direction orthogonal to the longitudinal direction to be coupled with each other near nodes of bending vibrations occurring at both free ends of the tuning bar vibrators. In this arrangement, since the tuning bar vibrators are coupled with each other, the mass of the composite vibrator increases. Thus, even when the length of the longitudinal direction of the tuning bar vibrator is reduced, due to the increased mass, higher sensitivity for the detection of an angular velocity can be obtained.
