Patent CA-2270831-A1 (CA)
Inventor: HUANG DAVID
IPC: A61F9/01
Filed: 1997-10-21
Abstract: This invention is a non-contact apparatus and method for performing laser thermal keratoplasty capable of scanning of treatment areas with shapes that reduce regression. The apparatus includes laser sources (70, 78, 40), a projection optical system, observation system, and control system. The projection system uses two steering mirrors (56, 58) to control laser beam position on the cornea. This projection system enables precise control of the area of corneal heat shrinkage using relatively low-powered lasers, such as diode lasers. Desired changes in corneal refractive power are produced by selected patterns of photothermal shrinkage of corneal collagen tissue. The selected patterns are arrangements of oblong shapes that are preferably tapered at the ends of the long axis. The oblong shape and tapering distribute tension in the cornea over a wider area of collagen shrinkage and improve the stability of refractive correction. The long axes of the oblong treatment areas are preferably oriented radially for hyperopia correction and circumferentially for astigmatism correction.

Title: Procede et dispositif pour inserer une image haute resolution dans une image interactive basse resolution, afin d'obtenir une impression d'immersion realiste
Inventor: MARTIN H LEE
IPC: G06T19/00
Filed: 1998-04-07
Abstract: L'invention concerne un procédé visant à insérer une image haute résolution dans une image interactive basse résolution, afin de donner une sensation accrue de réalité (présence) virtuelle, car le grossissement accru d'une image basse résolution, généralement grand angulaire, réduit ladite sensation dans l'image. Par exemple, selon l'invention, lorsque l'image d'un mur (2) d'une galerie d'art est agrandie dans un contexte de présence virtuelle, on remplace une partie rectangulaire ou autre partie plane, du type tableau (3) accroché au mur, d'une image sur laquelle l'utilisateur fait un zoom avant, par une image haute résolution enregistrée et associée en mémoire. On obtient l'effet de présence virtuelle par une exploration haute résolution sur telle ou telle section de portion d'image, aux fins de superposition sur l'image explorée, dans une seconde mémoire avec une résolution inférieure. L'image haute résolution destinée à l'insertion peut être une partie débarrassée de déformations d'une image interactive saisie par objectif fish eye. De préférence, au moins trois points de référence sur l'image grand angulaire et la portion d'image plane destinée à l'insertion, comme le tableau (3), sont identifiés et enregistrés avec les données d'image, suivant un niveau voulu ou préétabli de grossissement. Ainsi, les trois points d'image peuvent être manipulés et adaptés à la perspective de l'image grand angulaire, à partir de l'image haute résolution. Par ailleurs, aux fins d'identité de perspective, on peut saisir les images grand angulaire et haute résolution depuis le même emplacement de prise de vues. A mesure que l'utilisateur introduit des critères d'angle de vue (par exemple, angles de panoramique et d'inclinaison), il est possible de manipuler l'image rectangulaire pour adaptation. L'appareil de prise de vues peut être numérique, analogique, de type vidéo, cinématographique ou photographique. En outre, il est possible d'insérer une image photographique haute résolution dans une image graphique, et vice-versa.

Title: Use of a cd40:cd154 binding interruptor to prevent counter adaptive immune responses, particularly graft rejection
Inventor: THOMAS DAVID
IPC: A61K31/57
Filed: 1998-05-15
Abstract: Compositions and methods disclosed herein capitalize on the discovery that rejection of a tissue graft can be inhibited using a CD40:CD154 binding interruptor, either alone or in combination with another immunomodulator or immunosuppressor. An advantageous, synergistic combination includes a CD40:CD154 binding interruptor and a CD28 signalling interruptor. An exemplary CD40:CD154 binding interruptor is an anti-CD154 monoclonal antibody, such as an antibody having the antigen-specific binding characteristics of the 5c8 monoclonal antibody. An exemplary CD28 signalling interruptor is a CTLA4-Ig fusion protein. The disclosed compositions and methods unexpectedly can be used to prolong survival of grafted tissue in a recipient host, to reverse acute graft rejection, and to attenuate immunological consequences of the failure of grafted tissue.

Patent CA-2298796-A1 (CA)
Inventor: JOHARI GIRISH CHANDRA
IPC: G06F1/26
Filed: 2000-02-16
Abstract: A power subsystem for a computer system allows a voltage regulator module (VRM) to be removably connected to a system board, while limiting disturbances on the voltage rails of the system board. The electrical disturbances are prevented by charging voltage outputs of the DC/DC circuit of the VRM prior to directly connecting the voltage outputs to the voltage rails. To ensure that the voltage outputs are properly charged, a VRM connector may be used in which the voltage output pins are shorter than charge pins which are coupled to respective capacitors and to the voltage outputs of the DC/DC circuit. In this manner, as the connector is mated with a corresponding connector on the system board, the capacitors are first charged via resistive paths connected to the voltage rails, prior to directly connecting the voltage outputs to the voltage rails. The VRMs are thus "hot-pluggable," enabling a user to upgrade or service the system with no interruption.

Inventor: LEE STEVEN
IPC: G08B13/193
Filed: 2000-03-10
Abstract: A passive infrared sensor uses a modified lens or mirror to vertically elongate the detection zones in regions close to the sensor. This vertical elongation reduces the signal produced by a small pet, such as a cat, while the greater height of a human intruder produces a larger signal. The sensor advantageously uses a single detector and the same algorithm is used to distinguish human intruders from small pets.
