A system and method for determining acceleration along a motor axis of a MEMS gyroscope includes a processor. The processor includes a notch filter to remove a sinusoid from an instantaneous voltage from a motor pick up of the MEMS gyroscope. A memory bus allows random access to data stored in a processor readable memory. A processor-readable memory in operative engagement with the memory bus allows access to the processor-readable memory containing data. The data includes a model relating at least one instantaneous voltage in a remaining instantaneous voltage to an acceleration of a proof mass along the motor axis. Instructions to the processor include a routine to compare the at least one instantaneous voltage in the model to the remaining instantaneous voltage.

A sensor structure using vibrating sensor elements (1a, 1b, 1c, 1d) which can detect an angular rate and accelerations in two axes at the same time is provided. 2 sets of vibration units (1a, 1b; 1c, 1d) which vibrate in out-of-phase mode (tunning-fork vibration) and include four vibrating sensor elements of the approximately same shape supported on a substrate in a vibratile state are provided and the vibrating sensor elements are disposed so that vibration axes of the vibration units cross each other at right angles. Each of the vibrating sensor elements includes a pair of detection units (3a, 3b, 3c, 3d) and adjustment units (4a, 4b, 4c, 4d) for adjusting a vibration frequency. The vibrating sensor elements constitute a combined sensor having supporting structure for supporting the vibrating sensor elements independently so that the vibrating sensor elements do not interfere with each other.

An acceleration-detecting type gyro apparatus of an electrostatic supporting type, in which displacements of a gyro rotor are actively made zero is proposed. The acceleration-detecting type gyro apparatus includes: a gyro case; a gyro rotor which is supported within the gyro case by electrostatic supporting forces such that the gyro rotor is not in contact with the gyro case; electrostatic supporting electrodes for generating the electrostatic supporting forces; a rotor drive system for rotating the gyro rotor around the spin axis at high speed; a displacement-detection system for detecting displacements of the gyro rotor; and a restraining system having a feedback loop for correcting control voltages applied to the electrostatic supporting electrodes so that displacements of the gyro rotor become zero, the gyro rotor is annular-shaped, and the electrostatic supporting electrodes are disposed in a manner of surrounding the gyro rotor.

Capteur inertiel composite du type mécanique. Le rotor (1) et l'arbre d'entraînement (5) sont mécanique­ment reliés par une jante souple (3), déformable élasti­quement et agencée pour laisser au susdit rotor (1) trois degrés de liberté, à savoir un degré de liberté en translation selon l'axe de rotation arbre d'entraînement (5)-rotor (1), et deux degrés de liberté en rotation autour de deux axes formant un trièdre avec ledit axe de rotation. Un dispositif à moteurs couples (6) est prévu pour exercer sur le susdit rotor (1) au moins trois forces parallèles au susdit axe de rotation, et un dis­positif détecteur (7) est prévu pour déterminer la position du susdit rotor (1) par rapport à la structure du capteur.

In order to blur a virtual object in a video in real time as the video is acquired by a device capturing a real scene, a salient idea comprises estimating an apparent motion vector between two successive images, being captured at two successive device poses, wherein the apparent motion vector estimation is based on a motion of the device. The successive images are then filtered based on the estimated apparent motion vector.
