Patent CA-2197998-A1 (CA)
Inventor: DE WIT PAULUS PIETER
IPC: G11B7/244
Filed: 1995-08-10
Abstract: L'invention se rapporte au domaine des polymères liquides cristallins, notamment les polyéthers liquides cristallins que l'on obtient par polymérisation d'un mélange de monomères comprenant un composé contenant OH ainsi qu'un mono-époxyde contenant un groupe mésogène. Les polyéthers obtenus à partir d'un tel mélange de monomères se sont avérés posséder une température de transition vitreuse élevée bien qu'ils ne possèdent pas un poids moléculaire particulièrement élevé. En outre, ces polyéthers ont généralement une terminaison OH, et ils sont conçus pour être utilisés dans les couches retardatrices de dispositifs d'affichage à cristaux liquides, de stockage de données numériques tels que des disques compacts ou des films numériques, de stockage numérique à faible densité et de stockage de données analogiques; par contre, lorsque des matières colorantes sont présentes, les films contenant les polyéthers cristallins liquides selon l'invention sont utiles en tant que polariseurs.

Patent CA-2203394-A1 (CA)
Inventor: BRECHNER ERIC L
IPC: G06T15/00
Filed: 1995-10-26
Abstract: Selon un procédé de commande du niveau de détail relatif à un affichage infographique d'une structure complexe, celle-ci est modélisée en tant que volume global délimitant toutes ses parties, chacune de ces parties comprenant des sous-objets délimités dans des sous-volumes. Ce procédé consiste d'abord à sélectionner le volume global (202) puis à déterminer si tous les sous-objets présents dans le volume sélectionné sont effacés (204), et si oui, l'ensemble de l'affichage est éliminé. Si non, le système calcule alors les coordonnées-écran du volume sélectionné (208). Ce procédé consiste ensuite à déterminer si le volume sélectionné s'affiche sur l'écran ou déborde et dans ce cas, l'ensemble du volume est éliminé, mais dans le cas inverse, il détermine si tous les sous-objets sont affichés (214). Si tel est le cas, le nombre de pixels d'affichage nécessaires pour le volume sélectionné est calculé (216). Cette taille d'écran est comparée à un seuil défini par l'utilisateur (218) et si elle est inférieure à ce seuil, l'objet est dessiné sous forme de volume englobant (220). Si l'objet sélectionné présente une taille dépassant ce seuil, le procédé consiste alors à déterminer (230) si ledit objet présente des sous-volumes, et sinon, l'objet détaillé est dessiné (232). Si oui, le système renvoie chaque sous-volume (240) à l'étape permettant de déterminer si tous les sous-objets sont effacés (204), ce qui permet de déterminer, pour l'ensemble du volume global et tous les sous-volumes, le niveau de détail approprié à afficher. Pour un certain niveau de détail, la couleur d'un volume donné est déterminée par une sommation algébrique de la couleur de tous les sous-volumes d'un volume parent, pondérée par le rapport du sous-volume au volume parent élevé à la puissance 2/3. Ceci donne pour l'intensité de couleur des sous-volumes une pente correspondant sensiblement à l'inverse du carré du volume parent et produit des résultats satisfaisants.

Patent CA-2205873-A1 (CA)
Inventor: CUHACI MICHEL
IPC: H01Q1/36
Filed: 1997-05-22
Abstract: The attached document introduces a novel fixed beam planar reflector printed on a dielectric substrate. Realization of flat printed reflectors has previously been the subject of several patents such as: Munson et. al. (Us patent 4,684,952 dated Aug. 4, 1987), Gonzalez (US patent 4,905,014 dated Feb. 27, 1990), and Profera (US patent 5,543,809 dated Aug. 6, 1996). Phase front transformation is the underlying concept in all of the these inventions. The inventors have suggested various printed planar and non-planar configurations to transform the phase of the incoming wave into some other desired phase front. In one specific implementation, such structures have been proposed to replace the conventional reflectors ( where the reflector is curved surface) with that of a planar surface. A major drawback of printed implementations of such structures is that the phase shift mechanism is frequency dependent. This characteristic of previously reported printed reflectors bounds them to frequency scanned applications. In the frequency scanned application the antenna main beam shifts as the operating frequency is swept within the band. Due to this constraint the previously reported art can not be used in fixed beam applications. This deprives such areas as DBS (Direct Brodcasting Satellite), mobile communications and Satellite communications from a low cost, easy to manufacture and easy to deploy antenna candidate.   The current invention deals with methods of constructing fixed beam printed planar or nonplanar reflectors. The invention discusses the methods of phase correction due to frequency deviation for the printed planar equivalent of a conventional reflector but is not limited to that and it can be used in general to compensate the unwanted phase deviation as a result of frequency shift. In one implementation, a second reflective surface is used to fix the beam throughout the operating frequency band. In another implementation a "phase matched feed" is designed in conjunction with a planar printed reflector. Using this feed, a fixed beam is generated throughout the operating band. The design procedure for each case is discussed in detail and the measurement and computer simulated results are presented to substantiate the claims. Different variations of the patent will be discussed.

Title: Sound attenuating motor end shield
Inventor: HARWATH JULIE
IPC: F04C15/00
Filed: 1997-08-12
Abstract: A hydraulic pump-motor having an end shield which deadens the sound generated by the pump-motor do thereby result in a quieter unit.  The present invention provides a conventional hydraulic pump-motor having an electric motor coupled to a pumping mechanism wherein the motor includes an improved sound attenuating end shield design.  Through the use of acoustically deadening materials such as cast iron and polypropylene plastic, the end plates of the present invention deaden the sounds stemming from the vibration of the pump-motor. In addition, the present invention provides an end shield design which allows the stator to be secured to the motor housing and the air gap between the rotor and the stator to be precisely measured prior to the installation of the end shield.  The present invention therefore results in not only a quieter pump-motor but also a pump-motor with higher machining tolerances, improved efficiency, and lower production and maintenance costs.
