摘要： A rotation measurement system that includes at least two proof masses and at least one pick-off is provided. Each proof mass is driven in a first axis of motion. The at least one pick-off is configured to measure movement of the at least two proof masses in a second axis when the system is rotated about a rotation point and generate Coriolis signals and Euler signals based on the measured movement of the at least two proof masses.

摘要： A vibrating-mass gyroscope system includes a substantially planar vibrating-mass including opposite first and second surfaces and electrodes that extend longitudinally in a periodic pattern across the first and/or second surfaces. The electrodes include sets of drive and sense electrodes that are capacitively coupled to respective matching sets of drive and sense electrodes associated with a housing and which are separated from and facing the respective first and second surfaces. A gyroscope controller generates a drive signal provided to one of the array of drive electrodes and the substantially matching array of drive electrodes to provide for in-plane periodic oscillatory motion of the vibrating-mass, and generates a force-rebalance signal that is provided to one of the array of sense electrodes and the substantially matching array of sense electrodes to calculate rotation of the vibrating-mass gyroscope system about an input axis.

摘要： A rotation rate sensor includes a first rotationally suspended mass that exhibits a first axis of rotation. The first mass includes a first rotation-rate-measuring element that captures a first rate of rotation about the first axis of rotation and that outputs the first rate of rotation in a first signal. The sensor further includes a second rotationally suspended mass that exhibits a second axis of rotation and is arranged parallel to the first axis of rotation. The second mass includes a second rotation-rate-measuring element that captures a second rate of rotation about the second axis of rotation and that outputs the second rate of rotation in a second signal. The sensor further includes a propulsion device that propels the first and second mass and an evaluating device that outputs a difference of the signals as a third rate of rotation to be measured.

摘要： Provided herein is a method for determining a bias-compensated inertial rotation rate of a Coriolis vibratory gyroscope (“CVG”). The method comprises determining an initial mode that the CVG is operating; obtaining average uncompensated inertial rotation rate measurements from a previous mode transition period; obtaining average uncompensated bias measurements from the previous mode transition period; determining a first transition between a AGC mode and a FTR mode of a given axis; calculating a first estimate of bias of the CVG based on the first transition that was determined and the average uncompensated bias measurements from the previous mode transition period; and calculating, by a processor, a first bias-compensated inertial rotation rate of the CVG based on the first bias that was calculated and the average uncompensated inertial rotation rate measurements from a previous mode transition period.

摘要： An vibration element includes a drive vibration section and a detection vibration section, and the detection vibration section has a detection mode 1 and a detection mode 2 as an vibration mode for detection in which the detection vibration section resonates with Coriolis force produced in the drive vibration section and vibrates. A resonance frequency (vibration frequency) of the drive vibration section is higher than a resonance frequency (vibration frequency) in the detection mode 1 and a resonance frequency (vibration frequency) in the detection mode 2, or the vibration frequency of the drive vibration section is lower than the resonance frequency (vibration frequency) in the detection mode 1 and the resonance frequency (vibration frequency) in the detection mode 2.
