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 1, English, - position%20measuring%20device

La centrale à inertie est un appareil de mesure du positionnement très utilisé en raison de son autonomie et de sa faible sensibilité aux perturbations externes. On en trouve à bord des avions de ligne, des sous-marins, ou des missiles intercontinentaux. Elle est aujourd'hui souvent couplée à un GPS : ce système hybride permet de réduire les erreurs, et donc d'améliorer la qualité de la mesure.  1, record 1, French, - appareil%20de%20mesure%20du%20positionnement

The density of liquids can be measured with acoustic techniques. This is done by measuring sound velocity and acoustic impedance of the liquid. The presented work describes a novel ultrasonic density sensor that determines the sound reflection coefficient to measure the acoustic impedance of the liquid. It aims to be suitable for industrial applications by achieving a high measurement accuracy while meeting the mechanical and chemical conditions of the process. The high accuracy is obtained with the help of an additional reference measurement inside the sensor.  2, record 2, English, - density%20sensor

Seam Testing Methods... Electronic methods are the newest of the methods used to evaluate seam integrity. The ultrasonic pulse echo technique is basically a thickness measurement technique and is only for use with nonreinforced geomembranes. Here a high-frequency pulse is sent into the upper geomembrane and(in the case of a good seam) reflects off of the bottom of the lower one. If, however, an unbonded area is present, the reflection will occur at the unbonded interface. The use of two transducers, a pulse generator, and a CRT monitor are required.  1, record 3, English, - ultrasonic%20pulse%20echo%20technique
