Title: Systeme de reduction des fuites dans des circuits integres
Inventor: UVIEGHARA GREGORY A
IPC: H03K19/00
Filed: 2003-10-29
Abstract: L'invention concerne un système permettant de réduire des fuites de courant dans un circuit intégré. Ledit système comprend un premier composant de circuit et un second composant de circuit dans une voie entre un état de haute tension et un état de faible tension, telle que la terre. Un mécanisme de rétroaction fournit sélectivement une rétroaction d'une sortie du second composant de circuit vers une entrée du premier composant de circuit pour couper sélectivement la voie au niveau du premier circuit lorsque la voie n'est pas coupée au niveau du second circuit. Dans un autre mode de réalisation plus spécifique, un mécanisme de rétroaction préserve des données dans le circuit intégré par un multiplexeur qui permet sélectivement d'obtenir la rétroaction lorsque le circuit intégré est en mode veille. Les premier et second composants de circuit sont des inverseurs à semi-conducteur complémentaire à l'oxyde de métal (SCOM) à seuil à haute tension (HVT). La voie de rétroaction est choisie de sorte que lorsque la voie de rétroaction est activée, les voies de fuites situées à travers les inverseurs SCOM sont coupées.

Abstract: New structure for making a large screen or minor, such as used in a vehicle simulator, whereby such large structure is divided into a plurality of, preferably, identical segments (10, 11). Each segment, then, is made on the same mold or pattern which ensures an accurate radius of curvature and that the edges of each segment will co-act with the adjacent segment in a laterally non-slipping relationship. By this structure, the curved surfaces co-act together to define a smooth larger surface. Each segment is formed of expanded polyurethane foam (17) with the two surfaces (12, 13 and 15, 16) treated in different ways, depending on the use to which the structure is to be put.

Abstract: A universal abrasive cleaning apparatus comprising a plurality of arms (16) which are rotatably connected in series with one another. A plurality of nozzles (20) are connected to the distal end of the series of arms (16) by means of a nozzle support (18). Conduit means (30) interconnecting the nozzles to the source of abrasive and fluid are disposed within the interior of each arm thereby protecting the conduits from damage during manipulation of the arms. The proximal end of the series of arms is connected to a drum (22) rotatably disposed within a housing (24). The drum is powered by a motor.

Abstract: A tamper evident closure and package having a container (10), a resealable, substantially rigid closure (12) for closing, opening and reclosing the container (10), a color changing portion (32a in Figs. 1-6) which effects a color change upon stretching, and a coating mechanical arrangement (24, 36, 44 and 46 in Figs. 1-6) for uncapping and recapping the closure (10) and for stretching the color changing portion (32a) which clearly and unequivocally indicates the condition of the package, e.g., open or closed. Where legends, or other well defined indicia, indicating opening is desired, the color changes can be localized in the skirt by providing thin sections (32a) which stretch preferentially and adjacent thicker sections (38) which remain substantially unstretched. The thin sections (32a) for example can be legend, or alternatively the thick sections (38) can be the legend while the thin sections (32a) provide a suitable background. The color changes employed by the invention can be accomplished by such phenomena as stress whitening inherent in various plastic materials. Alternatively, the color changes can be accomplished by mechanism such as the use of encapsulated staining or coloring agents incorporated in a suitable matrix

IPC: G01F1/698
Filed: 1987-10-16
Abstract: A fluid flow detecting system and method wherein a pair of electrically heated matched temperature sensitive devices (11, 12) are used to measure fluid flow. One of the devices (11) is placed in a position out of the fluid flow to be measured but in thermal relation to the fluid such that the device (11) is affected by variation in ambient temperature. The other device (12) is placed in the flowing fluid to be measured. Thus, a change in flow rate results in a change in the ratio of dissipation coefficients of the devices (11, 12). Circuitry (17, 45) is coupled to each of the devices (11, 12) for maintaining the two devices at substantially equal temperature. A change in the ratio of the power in the device (11, 12) with respect to each other indicates a change in the dissipation coefficient ratio which is insensitive to variation in ambient temperature.

Title: Method to achieve a linear standard curve in a sandwich immunoassay
Inventor: TUNG KER-KONG
IPC: G01N33/543
Filed: 1988-04-13
Abstract: A method for obtaining an actual linear standard curve in a sandwich type of immunoassay where a first antibody bound to an insoluble support and a second unbound labelled antibody complex with the antigen contained in a test sample to form an insoluble antibody:antigen:labelled antibody complex which is then detected. Unbound unlabelled first antibody and/or unbound unlabelled second antibody are added to the reaction mixture to divert excess antigen away from the desired end-product complex, thus rendering the antigen of interest the rate-limiting factor in the overall immunoreaction. This results in a pseudo first-order reaction which produces an actual linear standard curve.

Title: Internal combustion engine noise reduction plate
Inventor: BALLHEIMER BENNY
IPC: F01M1/06
Filed: 1988-10-21
Abstract: Rigidifying or structural members are used to increase structural stiffness of cylinder block and consequently have reduced vibrations and noise emitted therefrom. These devices in the past have reduced serviceability, increased engine component complexity, increased cost and allowed additional interfaces for lubricant to leak therefrom. The subject structural member or rigidifying member (70) provides a simple, inexpensive, light-weight solution to increasing structural stiffness of cylinder block (12). The subject structural member (70) has an uninterrupted flange (76) therearound and a plurality of equally spaced longitudinally positioned openings (78) therethrough. The flange (76) is secured in frictional contact with the inner mounting surface (48) inside the oil pan (60). Thus, the interface for lubrication leakage of past members has been eliminated. The openings (78) have reduced the weight of the member and provide an opening through which the crankshaft can swing preventing the need to increase the engine height. The structural member (70) is free of connection with the main bearing caps (14) which reduces component complexibility, cost and simplifies serviceability.

Abstract: A method and apparatus for a containment for treating a surface, such as on an aircraft, in-situ. A treating compartment (29) having a conductive screen (34) and an insulating fiber member (37) therein is held in place on the surface (11) by a retaining membrane (14) attached around the periphery of the treating compartment (29). The treating fluid (40) is held in a separate container (42) that is coupled to the treating compartment (29). A suction is placed on the treating compartment (29) which pulls the membrane (14), screen (34) and fiber (37) against the surface (11) and into contact with each other. The suction also pulls the treating fluid (40) into the treating compartment (29). The fluid (40) spreads evenly along the insulating member disposed between the screen (34) and the surface under treatment. A voltage potential difference is placed between the conductive screen (34) and the surface (11), causing current to run through the treating fluid (40) to provide treatment of the surface (11).
