Abstract: A linear preload fluid power operated latch (10) has two coaxial pistons (42, 44), one (44) slidable inside the other (42) and the other (42) slidable within a cylinder (40). The one piston (44) slides inside the other (42) to cam dogs (30) which are slidable in slots of a nose (28) which is secured to the other piston (42) so as to engage an undercut (29) in a cup in which the nose (28) is received. After the dogs (30) are engaged in the cup (20), which secures the latch (10), both pistons (42, 44) are retracted to apply a linear preload force between the two bodies (14, 15) being latched. In one embodiment (22; 322), the pistons (42, 44; 342, 344) are moved in both directions under fluid pressure and in another embodiment (122; 222), both pistons (142, 144) are returned by compression springs (170, 172, 174; 270, 272, 274). In either case, the cup (20; 320) is drawn closer to the cylinder (40, 140, 240, 340) with a certain preload force, to latch a body (14) to which the cup (20; 320) is attached to a second body (15) to which the cylinder (40, 140, 240, 340) is attached with that preload force. An elastomeric isolator (32; 332) is interposed between the one body (14) and the cup (20; 320) so as to attenuate the transmission of vibrations from the cup (20; 320) to the body (14) or vice versa, and also to provide lateral and vertical compliance for helping to align the cup (20; 320) and locking unit (22; 122; 222; 322) with one another.

Title: Appareil et procede pour des matrices actives programmables
Inventor: SOSNOWSKI RONALD GEORGE
IPC: C12Q1/68
Filed: 1996-09-06
Abstract: L'invention concerne un système pour réaliser, par des méthodes de biologie moléculaire, des diagnostics, des analyses et des réactions à étapes multiples et combinées. Ce système comporte un dispositif micro-électronique auto-adressable et auto-assembleur permettant d'effectuer efficacement des réactions contrôlées à une échelle microscopique. De préférence, un dispositif fluidique fait circuler un échantillon sur la surface active d'une microplaquette dans des conditions permettant d'optimiser le diagnostic. De préférence, le dispositif fluidique comprend une cellule à flux continu ayant une fenêtre. Une activation pulsée des électrodes de la microplaquette du dispositif fluidique permet, d'une manière avantageuse, un échantillonnage plus complet du contenu de l'échantillon biologique. Un système de détection amélioré utilise une fibre d'excitation telle qu'une fibre optique, de préférence orientée coaxialement, cette fibre optique étant placée dans un guide optique, tel qu'un guide optique à liquide. De cette manière, on peut analyser la fluorescence en utilisant des dispositifs de taille réduite et assurer une analyse d'ADN à des fins diagnostiques, qui est hautement automatisée. Les changements du signal de fluorescence durant la dénaturation électronique sont examinés et analysés pour en tirer des renseignements d'ordre analytique ou diagnostique. Ces changements sont utilisées avec d'autres informations pour améliorer l'analyse. La cartographie de l'ADN est obtenue par une hybridation de fragments d'ADN d'une longueur donnée avec une séquence de capture au site testé, suivie de la détermination de la polarisation inverse nécessaire pour influer sur l'hybridation, par exemple pour provoquer une dissociation du produit de l'hybridation, ce qui permet de déterminer la longueur de l'ADN.

Abstract: A method and apparatus for interference cancellation in a high-speed modem are disclosed. The apparatus includes a first coupler for receiving a differential signal including a received data signal, a second coupler for deriving a common mode signal for the transmitted signal, and a phase-shift circuit coupled to the second coupler for deriving orthogonal signals from the common mode signal. First and second multipliers mix the orthogonal signals with the received signal. First, second, and third integrators integrate the mixed orthogonal signals and the common mode signal to produce signed orthogonal signal level measurements ITONE and QTONE and a common mode signal level measurement CMTOME, respectively. A controller derives orthogonal correction signals from measurements by dividing ITONE and ATONE respectively by CMTONE and multiplying by an appropriate constant. This output is then used to increment or decrement the signals to the respective digital to analog converters, DACI and DACQ. Multipliers combine these orthogonal correction signals to the orthogonal signals. An adder the combines the corrected orthogonal signals with the received signal for deriving the received data signal by cancelling interference therein.

IPC: F04D29/66
Filed: 1999-02-22
Abstract: A motor housing for a vacuum cleaner includes a main body, a peripheral rim, and an interconnecting base bounding portions of a working air chamber. A portion of the peripheral rim defines a sidewall having a plurality of vanes and a plurality of exhaust openings, with the vanes and the exhaust openings cooperating to exhaust air from the working air chamber in response to rotation of the impeller. Each of the vanes having an airfoil-shaped cross section, and each vane is oriented such that the airfoil of each vane is oriented oppositely relative to the airfoil of its adjacent vanes. Thus, a first set of the vanes are positioned to direct air through the exhaust openings, while a second set of vanes are positioned to direct excess air from adjacent the exhaust openings toward the chamber and back into the flow pattern. The excess air is thus smoothly remixed at a different velocity with the air moving through the working air chamber such that synchronization of the air flow is reduced, and harmonic induced noise is minimized.
