Abstract: ABSTRACT OF THE DISCLOSURE     A pseudo-luminous panel has a substrate and a thin film optical color filter formed all over the main surface of the substrate with or without a reflecting film inter-posed therebetween.  The main surface of the substrate is formed by obliquely downward and upward band-like surface portions alternately arranged side by side in a vertical direction.   Obliquely downward band-like surface portions of the reflecting film, formed on the obliquely downward band-like surface portions of the substrate, or the ob-liquely downward band-like surface portions of the sub-strate, are each a smooth reflecting surface. Obliquely upward band-like surface portions of the reflecting film, formed on the obliquely upward band-like surface portions of the substrate, or the obliquely upward band-like sur-face portions of the substrate, are each a smooth, irregu-lar or uneven reflecting surface. Obliquely downward band-like surface portions of the thin film optical  color filter are each a smooth surface extending straight in the longitudinal section of the panel, and obliquely upward band-like surface portions of the color filter are each a rough surface.     With the pseudo-luminous panel of such a structure, it is possible to prevent that a pattern on the panel is too dazzling in the daytime and too dark at night to recognize in a predetermined hue when the panel is set up out doors high above the ground.

IPC: B62M1/24
Filed: 1993-04-02
Abstract: PRÉCIS Le vélo traditionnel utilise un vilebrequin en guise de pédalier, afin de transmettre l'énergie humaine à la roue de traction. L'utilisation de ce vilebrequin ne permet de communiquer qu'une partie de la force appliquée De fait, sur une course de 360 degrés, seulement 90 degrés contribuent à générer cette force. Les 270 degrés qui restent à parcourir, en plus de ne transmettre aucune force consomment une partie de la force appliquée pour ramener le pédalier à son point de départ. La présente invention est un principe qui permet de remplacer le pédalier conventionnel par un pédalier qui est mieux adapté aux mouvements de balancier du corps humain. En effet, ce pédalier utilise un mouvement de va-et-vient sur une distance de 12 pouces et transforme ce mouvement en un mouvement de rotation efficace sur 360 degrés sans perte d'énergie.

Title: System and method for using an anamorphic fiber optic taper to extend the application of solid-state image sensors
Inventor: HOAGLAND KENNETH A
IPC: H04N5/335
Filed: 1993-01-25
Abstract: An apparatus and method for allowing television systems using solid-state image sensors to be compatible with a multiplicity oh television standards.     Scenes conforming to a standard which specifies a format aspect ratio or a specific number of active scan lines per frame are input into the anamorphic television system. The anamorphic television system modifies these scenes to take optimum advantage of the resolution of the solid-state image sensor. The anamorphic television system alters the dimensions of the scene along the horizontal and/or vertical axis so that the scene conforms to the format aspect ratio of the solid state image sensor and/or to the number of active scan lines per frame as specified in the applicable standard. The solid-state image sensor converts the optical information into an electrical signal. This electrical signal is retrieved from the solid-state image sensor by timing circuitry. The retrieved electrical information is converted into a composite video signal which is then displayed on the display monitor. The original proportionality of the scene is recaptured by altering the vertical and/or horizontal height controls on the display monitor and/or by altering the rate at which the information is retrieved from the image sensor and displayed on the display monitor.

Title: Agglutination reaction device having geometrically modified chambers
Inventor: PARSONS ROBERT G
IPC: B01L3/00
Filed: 1991-11-15
Abstract: Disclosed is a device for performing agglutination reactions comprising: in adherent relationship, a first wettable layer (1), a second liquid-occlusive layer (2) parallel to and overlying the first layer (1), and a third layer (3) parallel to and overlying the second layer (2) and having a window for observing particles.  The second layer is interposed between, and is in adherent relationship to the first and third layers. The second layer (2) has at least one general slot (25) defining a channel for directing liquid conducted by capillary action through a chamber defined by the slot in conjunction with the first (1) and third (3) layers. The chamber has a proximate zone and a distal zone. The geometry of the chamber is modified to provide flow paths having different rates of flow per unit area along the paths. This arrangement of such different paths in the chamber allows agglutination reactions in the chamber to result in the formation of a non-random pattern of aggregated particles in the distal zone of the chamber. Such a non-random pattern is more readily observable than a random pattern of aggregated particles.
