Laser Position Measurement. A commercially available position measuring device, Lasernet, was donated by the Namco Controls Corporation. A single narrow-beam laser is continuously swept across the field at a fixed height. A reflector of known geometry on the vehicle reflects the beam back to the device, which reports the initial angle, in the local geographic frame, at which a reflection is detected and the angular width over which the reflection is continuously detected. Knowing the geometry of the reflector, which should be independent of the heading of the aircraft, is sufficient to determine the vehicle's two-dimensional position in the local geographic frame. 1, record 4, English, - position%20measuring%20device

Rate gyro : Principles of Operation. The Crossbow DMU [dynamic measurement unit] contains three accelerometers and three angular rate gyros. The three angular rate gyros use vibrating piezoelectric ceramic transducers to measure the Coriolis acceleration. In the 1830's G. G. de Coriolis discovered that an object moving perpendicular to a rotating frame will cause an observer on the rotating frame to see an apparent acceleration of the object. 1, record 5, English, - vibrating%20piezoelectric%20ceramic%20transducer

Deux procédés s'offrent à lui pour mesurer la rotation instantanée de ce laboratoire : la mécanique rationnelle et l'optique. Mécanique rationnelle : par l'existence des forces d'inerties (centrifuges, gyroscopiques) cette voie conduit à la réalisation de gyromètres mécaniques décrits par des lois classiques (Galilée, Newton...) Optique : cette voie, par l'influence de la rotation du laboratoire (et par la suite des instruments utilisés) sur l'interaction instrument-lumière, conduit à la réalisation des gyromètres à fibres optiques et à celle des gyromètres laser. 3, record 12, French, - gyrom%C3%A8tre%20m%C3%A9canique

Un solide est un corps dont les différents points restent à des distances constantes les uns des autres au cours du mouvement. Un solide pouvant se mouvoir librement a sa position déterminée par la donnée de six paramètres : la position d'un point (trois coordonnées) et trois angles qui, dans le cas général, sont les angles d'Euler et, plus souvent, des angles adaptés au solide (par exemple pour un bateau, des angles correspondant au changement de cap, au tangage et au roulis). On dit que, dans le cas le plus général de mouvement, le solide possède six degrés de liberté. Des liaisons peuvent réduire les mouvements possibles et, en conséquence, diminuer le nombre de degrés de liberté; ainsi un solide en rotation autour d'un axe fixe à un degré de liberté. 3, record 14, French, - ensemble%20de%20navigation%20inertielle%20%C3%A0%20six%20degr%C3%A9s%20de%20libert%C3%A9

In the torque viscometer, a sensor (spindle) is rotated at some speed through the same couple arrangement which allows the sensor to be displaced to an equilibrium position at which point the calibrated torque spring gives a reference to the viscosity of the fluid being measured.

The rotating-vane-type viscosity measuring element depends upon the drag on a rotating member in contact with the material whose viscosity is to be measured. The vane or rotating element is driven by a synchronous electrical motor. The torque required to rotate the member of the vane is measured and is proportional to the viscosity in contact with the rotating element. The synchronous motor drives the cage at a constant speed. The upper spindle arm is coupled to the cage through a calibrated beryllium-copper spring. During measurement, the spring is wound up until its force exactly equals the viscous drag on the spindle; then the cage and spindle continue to operate at the same speed, but with a definite angular relationship to each other proportional to the torque on the spring. 4, record 15, English, - rotating%20spindle%20apparatus%20for%20measuring%20viscosity
