Patent CA-2175960-C (CA)
Inventor: DOERNER FRANK
IPC: A47C1/032

Granted: 2007-07-03
Abstract: A chair seat tilting mechanism comprises a support for mounting to a chair spindle and a lever arm pivotally mounted at a pivot to the support, which lever arm is for mounting to a chair seat. A link arm is pivotally mounted at a pivot to the support and has a cam with a camming end positioned between the lever arm pivot mount and the link arm pivot mount. An extension of the link arm mounts to a chair back such that when a chair occupant leaning back on the chair back, the link arm pivots about the link arm pivot causing the cam to cam lever arm so that it pivots about its own pivot with the support. This results in the chair seat tilting forwardly.

Abstract: An improved occlusion detector is provided in a medication infusion pump (10) to monitor medication delivery to a patient, and to provide an early alarm in the event of medication nondelivery. The detector comprises a force sensor (52) and related control circuit for reading and comparing the pressure applied to the medication at the time of pump operation to administer a dose to the patient, with the same pressure at a later point in time preceding the next dose. If a difference between the pressure readings is less than a predetermined value, an occlusion of the medication delivery line is indicated and an alarm is activated.

Title: 66 kda antigen from borrelia
Inventor: BERGSTROM SVEN
IPC: A61P31/04
Filed: 1995-06-19
Granted: 2009-04-21
Abstract: Nucleic acid fragments are disclosed which encode a polypeptide antigen reactive with antisera from rabbits immunised with a 66 kDa protein from Borrelia garinii IP90. The presence of nucleic acid fragments encoding such a polypeptide antigen as well as the presence of the polypeptide antigen have been demonstrated in three strains of B. Burgdorferi sensu lato, but are substantialle absent from at least 95 % of randomly selected B. hermsii, B. crocidurae, B. anserina, and B. hispanic a. The encoded polypeptide is surface exposed on the bacterial surface, it is highly conserved, and is thus potentially useful as a vaccine agent and as a diagnostic agent in the diagnosis of infections with B. burgdorferi as are the characteristic nucleic acid fragments of the invention. Also disclosed are methods of producing the polypeptide antigen according to the invention as are antibodies directed against the antigen.

Abstract: L'invention concerne des ensembles-embouts de fibres, à transmission optique, dans lesquels sont incorporées des particules diffusant un rayonnement, utilisés en photothérapie. Selon une variante, l'invention concerne des diffuseurs pourvus de capuchons terminaux réfléchissants. Lorsqu'un rayonnement se propage à travers l'embout de fibre, une partie des rayons est diffusée selon une configuration cylindrique (ou partiellement cylindrique) le long de l'embout de fibre. Le rayonnement qui n'est pas diffusé pendant ce passage initial à travers l'embout peut être réfléchi par au moins une seule face de l'ensemble embout et renvoyé à travers l'embout. Pendant ce second passage, le rayonnement résiduel (ou au moins une partie importante de ce rayonnement réfléchi) rencontre de nouveau les diffuseurs qui créent une autre diffusion radiale de ce rayonnement. Le milieu de diffusion et le capuchon terminal réfléchissant peuvent interagir pour produire une répartition axiale (ou autrement prédéfinie), pratiquement uniforme, du rayonnement laser sur la longueur de l'embout qui forme l'appareil présenté. Selon une autre variante, l'invention concerne des ensembles-boucles de diffusion qui servent à diffuser une rayonnement provenant d'une fibre optique. L'invention concerne également des gaines jetables ainsi que des dispositifs d'arrêt solidaires de l'embout qui limitent la pénétration de l'appareil. Les appareils selon l'invention peuvent être utilisés à différentes fins d'ordre médical ainsi que pour stériliser des instruments médicaux.

Title: Filtre a treillis de fil metallique
Inventor: VOLL BENN ARILD
IPC: B01D29/15
Filed: 1996-03-25
Granted: 2006-01-24
Abstract: Filtre comportant un treillis de fil métallique tissé (14) sur un corps formant support. Ce corps est généralement un tube de métal perforé qui permet le passage de fluide entre le puits et l'équipement de production. Le treillis de fil métallique tissé (14) sert de filtre en évitant l'entrée de particules de sable (30). Ses ouvertures sont orientées suivant différents angles par rapport à sa surface, ce qui fait qu'une certaine surface permet l'entrée de fluide même lorsque de la matière particulaire s'est fixée sur la surface au-dessus d'une ouverture. Des canaux intérieurs permettent au fluide de circuler d'un site de la surface du treillis à un autre site situé au-dessus d'une ouverture de la surface du corps. Le filtre ne comporte pas d'ouvertures à trajet direct, ce qui oblige le fluide à faire des détours multiples (28) pour traverser le treillis. On arrive ainsi à dissiper l'énergie du fluide et à augmenter la résistance à l'usure du treillis. Lorsque de la matière particulaire s'accumule à la surface du treillis, l'agglomérat de particules qui en résulte reste poreux, ce qui augmente la résistance du filtre à l'obstruction.

Title: Method and apparatus for navigating close proximity routes with a vehicle navigation system
Inventor: ZUBER GARY
IPC: G08G1/0969
Filed: 1997-12-05
Granted: 2001-02-27
Abstract: A method and apparatus are provided for generating a route from a source location to a destination in a vehicle navigation system. Initially, the system generates a first partial route from the source location to the end of the first partial route. The system then determines whether a second maneuver is within a first distance from a first maneuver at the end of the first partial route. Where the second maneuver is within the first distance, the system increases the cost associated with the second maneuver. The system then generates a second partial route from the end of the first partial route to the destination, generation of the second partial route being based at least in part on the cost associated with the second maneuver.

Le dispositif comporte également un régulateur à bouclage permettant de réguler le niveau du courant actif par variation des amplitudes de la tension ou du courant impulsionnel. Le procédé de régulation de courant du dispositif consiste à déterminer la valeur du courant actif et à réguler par une boucle la valeur du courant actif.
