Patent CA-2319087-A1 (CA)
Inventor: DEVORE DALE P
IPC: A61K45/00
Filed: 1999-01-28
Abstract: L'invention concerne une méthode accélérée d'orthokératologie dont les diverses étapes consistent: à amollir la cornée (10) à l'aide d'un agent amollissant, à appliquer un moule (36) pour redonner à la cornée (10) une courbure antérieure voulue, et à rapidement restabiliser ou "fixer" les tissus cornéens de manière que la cornée conserve sa nouvelle configuration. Un agent amollissant chimique, tel que l'anhydride glutarique, est appliqué sur la cornée (10) afin de l'amollir, puis un moule (36) spécialement conçu présentant une courbure et une configuration prédéterminées est appliqué sur la cornée. On applique une pression sur le moule pour reprofiler la cornée. Le moule (36) est maintenu en place, tandis qu'un agent stabilisant, tel qu'une source (96) de rayons ultraviolets, est positionné au-dessus du moule (36). L'agent stabilisant, c'est-à-dire le rayonnement ultraviolet, est appliqué sur la cornée (10), ce qui permet à l'agent stabilisant de restabiliser immédiatement les tissus cornéens de manière que la cornée conserve sa forme lorsqu'on retire le moule (36).
Patent CA-2321730-A1 (CA)
Inventor: KORKOSZ RICHARD AUGUST
IPC: H01Q1/32
Filed: 1999-03-03
Abstract: A system for directing a receiving lobe of an adaptive antenna array toward an aircraft in flight includes an aircraft position vector calculator and an antenna weight vector generator. The aircraft position vector calculator receives aircraft position information from an aircraft tracking service and calculates, based upon the aircraft position information it receives, an aircraft position vector g. An antenna weight vector generator receives the aircraft position vector g from the aircraft position vector calculator and generates, based upon the aircraft position vector g, an antenna element weight vector w. The antenna weight vector w is applied to the elements of an adaptive antenna array to direct a receiving lobe of the array towards an aircraft in flight.

Patent CA-2335839-A1 (CA)
Title: Optical ferrule and method of molding the same, and optical connector using the same
Inventor: NISHIMURA AKITO
IPC: G02B6/38
Filed: 2000-04-20
Abstract: An optical ferrule is disclosed in which a concave portion having a gate in resin molding disposed therein is formed in a ferrule body. According to this constitution, it is possible to easily cut a flash left after a gate of the concave portion of the ferrule body is cut after molding with a gate cutter, so that, when the ferrule body is fitted in a housing of an MPO connector and the like, the problem that the flash protrudes from the concave portion and the flash hitching to an inner wall of the housing does not occur. Accordingly, the labor required for removing the flash by polishing can be eliminated, and hence productivity of the ferrule body can be improved. Thus, a large number of ferrule bodies can be automatically manufactured without requiring much manpower.

Title: Flame simulating assembly
Inventor: HESS KRISTOFFER
IPC: G09F19/12
Filed: 2002-03-26
Abstract: The invention provides a flame simulating assembly for providing an image of flames transmitted in a fluctuating light. The flame simulating assembly has a simulated fuel bed, a light source, a screen disposed behind the simulated fuel bed for diffusing and transmitting light, and a flicker element for creating the fluctuating light, the flicker element being positioned in a path of light from the light source. The simulated fuel bed defines a profile viewable by an observer. In addition, the screen includes a curved portion which is curved in a vertical direction and in a horizontal direction to correspond to the profile of the simulated fuel bed. Also, the curved portion of the screen is positioned adjacent to the simulated fuel bed. The fluctuating light transmitted through the screen is attenuated and a three-dimensional image of flames appears to curve around the profile of the simulated fuel bed.
