Title: Systeme d'alignement temporel multimedia
Inventor: CHOW CHING TONG
IPC: H04N5/44
Filed: 1999-03-04
Abstract: L'invention permet à l'utilisateur de mémoriser des émissions de télévision choisies tandis qu'il regarde ou visualise simultanément une autre émission. Un mode préféré de réalisation de l'invention accepte des trains de signaux d'entrée de télévision (TV) sous une multitude de formes analogiques et numériques. Ces trains de signaux (TV) sont convertis en un train formaté (MPEG) en vue de leur transfert et de leur manipulation internes et sont analysés et séparés en composantes vidéo et audio. Ces composantes sont stockées dans des mémoires tampons. Sont enregistrés des événements qui indiquent le type de la composante ayant été trouvée, son emplacement et le moment de son apparition. La logique du programme est informée qu'un événement s'est produit et les données sont extraites des mémoires tampons. L'analyseur et la mémoire tampon d'événements évitent à l'unité centrale d'avoir à analyser le train MPEG et la rendent indépendante de la nature "temps réel" des trains de données, ce qui permet des vitesses plus faibles de l'unité centrale et du bus et se traduit par des coûts système inférieurs. Les composantes vidéo et audio sont stockées dans une mémoire et lorsque l'émission est appelée pour affichage, les composantes vidéo et audio sont extraites de la mémoire et réassemblées en un train MPEG qui est envoyé à un décodeur. Ce décodeur convertit le train MPEG en signaux de sortie TV qu'il délivre à un récepteur TV. Les instructions de commande données par l'utilisateur sont acceptées et envoyées à travers le système. Ces instructions modifient le flux dudit train MPEG et permettent à l'utilisateur de visualiser des émissions mémorisées, avec au moins les fonctions suivantes: retour, avance rapide, lecture, pose, indice, lecture arrière rapide/lente, et lecture rapide/lente.

Title: Hydraulic system with cross function regeneration
Inventor: STEPHENSON DWIGHT B
IPC: F15B11/00
Filed: 2001-03-14
Abstract: A regeneration method for a hydraulic system enables the fluid being forced from a first actuator to be used to power a second actuator. Often the force of the load acting on a hydraulic actuator is used to move the actuator into a given position which motion forces fluid from the actuator. Rather than simply draining that fluid to the system tank, the fluid is routed to a second actuator to be powered when the pressure of the fluid draining at the first actuator is greater than the pressure required to power the second actuator. At other times the draining fluid can be used to drive the pump which has been configured to operate as a motor thereby driving the prime mover connected to the pump. Alternatively the draining fluid can be routed to an accumulator where it is stored under pressure until needed to power an actuator of the system. A unique bidirectional pilot operated poppet valve

Inventor: PERRICHON CLAUDE ANNIE
IPC: G03B21/62
Filed: 1999-08-20
Abstract: Television images are presented by projecting light on a screen or sensitive film, while for photographs ambient light is used. The invention concerns a method for adding another additional light dimension so as to reduce the medium polarising effect. It consists in at least one electromagnetic spectrum light diffusing in a zone perpendicular to the image light emission, tangential to the image. In a non-exclusive example an apparatus is used showing an observer perceiving a photograph on paper. The usual ambient light is normally reflected by the photograph, whereto is added a light on the periphery and in the photograph medium. The lamp is masked from the observer. Said light diffuses into the photograph material and slightly behind by grazing, brushing the rear surface of the paper. The method also consists in using for television screens the direct light partially diffracted into a radial perpendicular spectrum, by a specific structure of the screen. The method and apparatus are useful in the fields of photography and audio-visual providing depth to the image, close to the original.

Title: Process for the preparation of beta-gamma unsaturated esters
Inventor: BURKE PATRICK MICHAEL
IPC: C07C67/38
Filed: 1999-11-30
Abstract: A process for the carbonylation of allylic butenyl ether (e.g., methyl crotyl ether, 3-methoxybutene-1 and mixtures thereof) or mixture of butadiene and alcohol (e.g., methanol) and production of beta-gamma unsaturated carboxylic acid esters (e.g., methyl-3-pentenoate) utilizing a rhodium-containing catalyst (e.g., dicarbonylacetylacetonate rhodium(I) or the like) promoted with an iodide-containing compound (e.g., HI, AlI3, SnI4, TiI4, CrI3, and CoI2 or the like). Such a process is particularly useful in the production of difunctional monomers and intermediates in the synthesis of adipic acid. The representative reaction showing (a) butadiene in the presence of methanol under catalytic reaction conditions producing the 3-methoxybutene-1 intermediate (a positional isomer of methyl crotyl ether) which is then combined with carbon monoxide to produce methyl pentenoate is illustrative of the overall carbonylation.

Title: Cannula stent
Inventor: FEARNOT NEAL E
IPC: A61F2/91
Filed: 1999-12-16
Abstract: A stent (10) formed from cannula and having flexible segments (11) and high hoop strength segments (12) alternating therealong.  Axial tie bars (21, 22) interconnect the segments; minimal length reduction would occur upon expansion. In the high hoop strength segment (12), struts (16) are initially parallel in the unexpanded strut condition, while in the flexible segment (11), struts (14) extend from a respective bight (15) to converge at distal ends when unexpanded. In one embodiment, certain adjacent struts (16) of the hoop segment are spaced apart by a large gap (20) while others are spaced apart by a small gap (18).  In another embodiment all the struts (16) of the hoop segment are spaced apart uniformly from each other (or from an axial tie bar) by a small gap (23), resulting in minimizing the occurrence of fatigue of high-stress sites upon expansion/contraction cycles from continuous pulsatile events.

Inventor: COLLINGS BRUCE A
IPC: H01J49/42
Filed: 1999-11-09
Abstract: A method is provided of operating a mass spectrometer apparatus comprising a pair of quadrupole rod sets. Each quadrupole rod set is operated in a mass resolving mode. They may be operated in the same or different stability regions. The rod sets are operated to select essentially ions of the same mass to charge ratio, and are operated such that the combined resolution of the two rod sets is greater than the resolution of either rod set. The rod sets can be operated at relatively low resolution, with the combined peak shape from the two rod sets showing high resolution. This can make up for mechanical imperfections in the rod sets, losses due to high gas pressures, etc. A mass shift can be provided to give the desired resolution. The rod sets can be close coupled, and for this purpose neutralizing capacitors can be provided to prevent electrical interference between adjacent rod sets. The rod sets can be provided with the same frequency signal, which preferably is a phase locked and shifted, to give enhanced sensitivity.

Patent CA-2362173-A1 (CA)
Inventor: SWARINGEN STEPHEN N
IPC: B23K26/06
Filed: 2000-02-10
Abstract: A Q-switched solid state laser system (24) operates in a pulse processing control system (10) that employs an autopulse mode and a pulse-on-position mode to stabilize the pulse-to-pulse laser energy delivered to a workpiece (20) that is moved by an X-Y positioner (18). In the autopulse mode, laser pulses are emitted at a near maximum PRF, but the pulses are blocked from reaching the workpiece by an external modulator (28, 32), such as an acousto-optic modulator ("AOM") or electro-optic modulator (also referred to as a Pockels cell). In the pulse-on-position mode, the laser emits a pulse in response to the positioner moving to a location on the workpiece that coincides with a commanded coordinate location. The processing control system delivers a stream of coordinate locations, some requiring processing, at a rate that moves the positioner and triggers the laser at about the near maximum PRF. The pulse processing control system sets the AOM to a transmissive state whenever a coordinate location requiring processing is commanded and otherwise sets the AOM to a blocking state. This pulse timing technique provides a nearly constant interpulse period for the laser, thereby improving its pulse-to-pulse energy stability at the near maximum PRF.
