Title: A method and apparatus for testing the response of a stress wave sensor
IPC: G01R31/00
Filed: 1990-03-09
Granted: 1993-10-06
Abstract: The invention relates to a method and apparatus for testing the response of a stress wave sensor (10) to confirm that the transducer (12) and amplifier (20) are functioning satisfactorily. A pulser (24) is connected to the stress wave sensor (10) at a point between the transducer (12) and the amplifier (20). The pulser (24) supplies a first and a second electrical pulse in series to the stress wave sensor (10). The first electrical pulse has a large amplitude such that it causes an operative transducer (12) to oscillate and produce an additional electrical pulse. The first electrical pulse and the additional electrical pulse are supplied to the amplifier (20). An operative amplifier amplifies the first electrical pulse and any additional pulse to give an output signal, the output signal indicates if either the transducer or amplifier are not operating satisfactorily, The lack of an output signal indicates the amplifier is inoperative. The second electrical pulse has a predetermined amplitude and is supplied to the amplifier, and is amplified by an operative amplifier to give a measure of the gain of the amplifier.

Abstract: An RF signal is transformed (12 and 12') to increase its current component, while reducing its voltage component below the voltage that would damage a GaAs switching device (16 or 16'). The current and voltage transformation are selected so that the power of the RF signal remains substantially constant. Subsequent to the GaAs switching device, the signal is converted (24 and 24') to increase the voltage component while decreasing its current component to substantially recreate the original RF signal.

Abstract: L'invention a pour objet un système d'armes constitué d'une pluralité de mines, pour la défense d'une zone. Chacune des mines comporte notamment une rampe de lancement dans laquelle est disposé un projectile contenant une charge militaire, des moyens d'initialisation qui assurent notamment la mise en position de la rampe de lancement et des moyens de détection de cible. Selon un mode de réalisation, la détection d'une cible par une mine a pour effet le lancement du projectile dans la direction de la cible, de sorte que celui-ci soit en auto-rotation autour de son axe longitudinal et conserve sur sa trajectoire une attitude de vol constante. Selon un autre mode de réalisation, les mines sont susceptibles de dialoguer entre elles pour opérer une attaque simultanée d'une pluralité de cibles situées dans la zone défendue. Le projectile comporte des moyens de détection de la cible, liés au projectile et émettant un faisceau d'énergie rayonnée qui effectue un balayage du sol en bandes (hyperboles) successives. La détection de la cible entraîne la mise à feu de la charge militaire. L'axe de celle-ci fait avec l'axe longitudinal du projectile un angle déterminé pour que l'empreinte au sol soit maximum et en tenant compte des valeurs désirées pour l'angle d'attaque de la cible (de préférence par le toit).

Abstract: The device comprises at least two oscillating rods which are attached, at a given distance apart, to a membrane, the edge of which is connected to a screwed piece. On the side of the membrane remote from the oscillating rods, a tensioning screw is ridigly connected to the membrane so that the tensioning screw and the membrane adopt a position relative to each other in which the axes of symmetry coincide. The tensioning screw is surrounded by a pile of annular piezoelectric elements, electrodes and insulating rings. This pile consitutes the exciting and receiving transducer of the device. The transducer is clamped and fastened between the membrane and a hexagonal nut. The pile thus rests on pressure points arranged between the membrane and a metal ring which terminates the pile. The clamping force is chosen so that the membrane is simultaneously pretensioned in a concave shape. The exciting transducer causes the oscillating rods to oscillate at their natural resonance frequency in opposite directions and perpendicular to their longitudinal axes. Any change in the oscillating behaviour of the oscillating rods is detected by the receiving transducer and used to determined and/or monitor the predetermined volume. It is thus possible to exploit both the frequency and the amplitude of oscillation of the oscillating rods.

Abstract: The speed of a supercritically operated electric machine can be increased over a range between a first critical speed and a second critical speed. To this end, the shaft (11, 12) of the electric machine is elastically mounted on either side of the rotor (7). The flexural strength of the shaft (11, 12) between the rotor (7) and the second bearing (8) is substantially greater than in the region between the rotor (7) and the first bearing (9). As a result, the second critical speed shifts to higher speeds more readily than the first critical speed, and the difference between the first and the second critical speeds, and thus the maximum range over which the speed of the machine can be controlled, increases. The invention can be applied in supercritically operated, variable-speed electrical machines.

Abstract: An electrostatic spraying device in which liquid emerging from an outlet of the device nozzle (12) is subjected to an electrical field sufficiently high for the liquid to be drawn from the outlet as one or more ligaments which break up into charged droplets to form the spray. The device is adapted for the spraying of targets which are conventionally difficult to coat electrostatically, eg. targets of insulating material. This is achieved by the use of circuitry (18, 20, 22, 24) which generates a bi-polar high voltage output having a frequency such that successive clouds of particles are charged with opposite polarity but do not discharge each other in flight. In this way, the charge applied to the particles is effective to assist seeking of the target without leading to build-up of charge on the target. <IMAGE>
