The gyros are used to maintain the platform's inertial orientation by sensing rotations of the platform caused by vehicle-rotation-induced friction at the gimbal pivot points... One gyro-called the vertical gyro-is oriented so its input axes are aligned with the X and Y platform axes; its input axes provide IMU [Inertial Measurement Unit] platform roll and pitch stabilization. The second gyro is oriented so that one input axis lies along the platform's Z axis and the other lies in the X-Y plane. This gyro-the azimuth gyro-provides platform yaw stabilization with the Z input axis, while the second input axis is used as a platform rate detector for built-in test equipment. 3, record 2, English, - azimuth%20gyroscope

The sensors for angular velocity are vibrating gyroscopes (3 axes, to detect rotation and pitch/roll pendulations of the payload). An error signal is obtained differencing the signal from the azimuth gyroscope and a constant level settable from the telemetry, which controls the speed of rotation. Such error signal drives an analog PID [Proportional Integral Differential] circuit; the output of the PID is connected to the PWM [Pulse Width Modulation] driver supplying current to the pivot azimuth motors. 3, record 2, English, - azimuth%20gyroscope

The single-axis inertial platform... The angular motions of the controlled member are sensed by the single-axis gyro. The output signal of the gyro is electronically processed and fed to the torque motor(TM) of the stable element and to the torque generator(TG) of the gyro. The problem is to determine how to do the electronic processing so that the controlled member maintains its orientation in spite of disturbances. The voltage across the output signal generator(SG) of the gyroscope is proportional to the integral of the angular velocity of the controlled member about the gyroscope's input axis. Consequently, this signal is fed to an amplifier and then to a motor, which drives the controlled member in the proper direction to null the ouptut of the gyroscope. 1, record 3, English, - output%20signal%20generator

The on-orbit Attitude Determination and Control Subsystem(ADACS) provides three axis pointing control for the satellite. The ADACS maintains system pointing by controlling torque in three mutually orthogonal wheels. The torque is determined by analysis of spacecraft orientation in space. Input to these computations are acquired from the Earth Sensor Assembly(ESA) for pitch and roll, and an inertial reference with sun sensor updates for yaw. 2, record 12, English, - inertial%20reference

The intercontinental ballistic missiles (ICBM) and submarine-launched ballistic missiles (SLBM) developed over the past 50 years have employed successive generations of increasingly accurate inertial guidance systems. The comparatively short time of guided flight and high acceleration levels characteristic of the ballistic missile application place a premium on accelerometer performance to achieve desired weapon system accuracy. To date, the accelerometer design of choice for strategic missiles has been the Pendulous Integrating Gyroscopic Accelerometer (PIGA) instrument, an accelerometer whose origins trace back to the German V2 rocket, and has been refined through several generations of development to achieve unsurpassed performance. 4, record 21, English, - pendulous%20integrating%20gyroscopic%20accelerometer

Integrated Cantilever Beam Tunneling Sensor. Our researchers have exploited the extremely sensitive quantum tunneling effect between metals to design MEMS sensors that can sense a force applied to a silicon-based, surface micromachined structure with extraordinary sensitivity and six orders of magnitude of dynamic range. The force is applied to a micromachined cantilever (one electrode) and is sensed as a result of a tunneling current produced between the cantilever and a tunneling tip (the other electrode). The sensor is operated in a force rebalance mode such that the cantilever and tip do not actually move with respect to each other but are held in a servo-locked state with the voltage required to maintain the servo-lock proportional to the force being sensed by the cantilever. 2, record 30, English, - force%2Drebalance%20mode

Dans cette étude de la quantification, le mouvement est supposé le résultat d'échanges de matière entre l'électron et le proton. Ces échanges prennent place dans toutes les directions de l'espace. De ce fait la rotation orbitale doit être considérée comme le résultat d'une action mécanique qui agit dans deux directions orthogonales. En d'autres termes la rotation peut être considérée comme la somme de deux rotations orthogonales. Il en résulte que le champ magnétique qui correspond à une action sur une seule direction de plans ne peut modifier que la moitié de l'action associée à la rotation. D'autre part les doublets ont en fait pour origine la possibilité pour l'électron de pouvoir tourner pour une même quantification angulaire avec une masse constante ou variable indépendamment de la vitesse radiale et rien n'indique que les doublets correspondent à des états de spin-up et de spin-down. 1, record 33, French, - quantification%20angulaire

The nuclear magnetic resonance(NMR) gyroscope is a rate-integrating, single-axis gyro that obtains its rotational information from the dynamic angular motion of certain nuclei... The NMR gyro utilizes the intrinsic property of certain nuclei to determine angular displacement about a defined input axis. These nuclei have angular momentum, hence magnetic moment. 5, record 38, English, - magnetic%20moment

Le principe de la résonance magnétique repose sur le fait que lorsqu'un moment magnétique situé dans un champ magnétique est soumis à une excitation magnétique périodique, son comportement n'est influencé par l'excitation que si celle-ci à une fréquence bien déterminée. Cette perturbation affecte le comportement électromagnétique de l'échantillon étudié et peut être mesurée. On obtient alors une courbe de variation appelée raie de résonance. La mesure directe de la résonance magnétique a été améliorée à l'occasion des études sur les radars pendant la Seconde Guerre mondiale. 6, record 38, French, - moment%20magn%C3%A9tique

Lévitation magnétique [...] - rotation: il est possible de faire léviter un objet avec des aimants fixes. Un exemple en est le lévitron : il s'agit d'une toupie aimantée qui est en lévitation au-dessus d'une base aimantée. En fait, le lévitron peut être considéré comme une sorte de corps diamagnétique : par rotation, on stabilise la direction du moment magnétique dans l'espace (on a un gyroscope magnétique) et on place cet aimant dans un champ magnétique anti-parallèle. 7, record 38, French, - moment%20magn%C3%A9tique
