Title: Modular power step
Inventor: PASCOE DAVID MARK
IPC: B60R3/02
Filed: 1999-01-19
Abstract: A power-retractable step assembly for a motor vehicle comprises a substantially sealed housing assembly (12), a pivoting structure (14) including a step structure, a gear assembly, and a motor assembly (18). The step structure presents an upper load carrying surface, and the pivoting structure is mounted for pivotal movement about an axis. The gear assembly is disposed in the sealed housing assembly and coupled to the pivoting structure. The motor assembly is drivingly coupled with the gear assembly and is constructed and arranged to pivot the pivoting structure about the axis and thereby drive the pivoting structure between deployed and stored positions. The step structure is moved in an outboard vehicle direction when the pivoting structure is moved from the stored position to the deployed position, and is also moved in a for-aft vehicle direction when the pivoting structure is moved between the stored and deployed positions. The axis is disposed at an angle such that, as the axis extends upwardly, i) the axis extends in the outboard vehicle direction and ii) the axis extends in a same fore-aft vehicle direction as the fore-aft direction that the step structure moves when the pivoting structure is moved from the stored position to the deployed position.

Title: Electrocatheter for inducing vessel stenosys having two arrays of diverging electrodes
Inventor: TARTAGLIA JOSEPH M
IPC: A61B18/08
Filed: 1999-08-20
Abstract: A catheter includes a first plurality of expandable leads (100) and a second plurality of expandable leads (102) separate and longitudinally spaced-apart from the first plurality to deliver energy to a hollow anatomical structure, such as vein, fallopian tube, hemorrhoid, esophageal varix, to effectively ligate that structure. Each of the leads includes an electrode located at the distal end of the respective electrode lead. Polarizations of the leads may be selected to achieve the power distribution desired. Each electrode lead includes an outward bend such that when a movable sheath (108) is moved out of contact with the leads, they expand outwardly into apposition with an inner wall of the structure to be ligated. High frequency energy can be applied from the leads to create a heating effect in the surrounding tissue of the anatomical structure. The diameter of the hollow anatomical structure is reduced by the heating effect, and the electrodes are freely moved inward by the shrinking structure while still maintaining apposition with the inner wall of the shrinking structure.

Title: Hybrid metal matrix composites
Inventor: LO JASON SIN HIN
IPC: B22D27/00
Filed: 2001-09-12
Abstract: A hybrid composite reinforced metal matrix in which the metal is aluminum, aluminum alloy, or a magnesium alloy containing a relatively high percentage of aluminum. In addition to the reinforcement, which is typically alumina, the metal matrix also includes a hardening agent which is at least one intermetallic compound of aluminum with at least one second metal chosen from iron, nickel, titanium, zirconium, cobalt and niobium. The metal matrix optionally also includes graphite as a wear resistant agent. The intermetallic compound(s) can be added as a powder to the metal matrix during formation of the composite, or can be created in the composite by adding the at least one second metal as a powder to the molten metal matrix during composite preparation. If the intermetallic compound is created in the composite, the composite when made initially can be readily machined and is self hardening through repeated heating cycles. The composite finds use in brake parts, such as brake rotors and brake drums as a replacement for the commonly used grey cast iron and exhibits adequate strength and compression properties up to a working temperature of at least about 450ÀC.

Abstract: Square and octagonal building elements for a set of toy building elements that are capable of being inteconnected in a releasable engagement both side-to-side and top-to-bottom. The side walls of the building elements include a groove and/or a split flexible tongue that is compressed when frontally forced into a groove in another such building element to effect a releasable restraining frictional engagement within the groove. The degree of frictional engagement provided by compression of the tongue when a distal portion of the tongue resides in a base region of the groove is such as to enable a stationary relative disposition of a pair of so engaged building elements to be varied precisely by smoothly sliding the tongue of one of the pair of engaged building elements within the groove of the other of the pair of engaged building elements, and also is such as to provide enough resistance to sliding as to maintain the stationary relative disposition when one of the pair of engaged building elements has the top of its engaged side wall disposed at a greater height than the top of the engaged side wall of the other of the pair of building elements. The tongues and the grooves are also dimensioned so that less force is required to effect engagement by frontally pressing the building elements together than is required to effect disengagement by frontally pulling the building elements apart.

Abstract: L'invention se rapporte à un procédé de commande sélective des couleurs d'une image vidéo numérique, au moyen d'une technique numérique. Ledit procédé est caractérisé par l'utilisation de tables de consultation (LUT look-up tables) dont les valeurs sont calculées à partir de fonctions de commande des couleurs définies de manière unique, pour permettre un changement numérique de la saturation d'une couleur unique de la partie chromatique d'une image vidéo sans altération des saturations des autres couleurs de la partie chromatique de la même image vidéo. Une image d'entrée vidéo numérique est balayée, ligne après ligne, pixel après pixel. Chaque valeur de pixel d'une image d'entrée, définie à partir de la partie chromatique de l'image d'entrée vidéo, est associée à une adresse destinée à servir à des opérations impliquant des valeurs dans des tables LUT de couleurs individuelles. Lorsqu'un changement est souhaité dans une couleur individuelle de cette image, une nouvelle image de sortie vidéo numérique est produite avec le changement souhaité de couleur individuelle sans que cela n'altère les autres couleurs de cette même image.
