Patent CA-2379822-A1 (CA)
Title: Flexible, modular, compact fiber optic switch improvements
Inventor: NEUKERMANS ARMAND P
IPC: H04B10/291
Filed: 2000-07-21
Abstract: A fiber optic switch (400) includes a fiber optic switching module (100) tha t receives and fixes ends (104) of optical fibers (106). The module (100) includes numerous reflective light beam deflectors (172) arranged in a V-sha pe which may be selected as pairs for coupling a beam of light (108) between a pair of optical fibers (106). The module (100) also produces orientation signals from each deflector (172) which indicate its orientation. A portcard  (406) supplies drive signals to the module (100) for orienting at least one deflector (172). The portcard (406) also receives the orientation signals produced by that deflector (172) together with coordinates that specify an orientation for the deflector (172). The portcard (406) compares the receive d coordinates with the orientation signals and adjusts the drive signals supplied to the module (100) to reduce any difference between the received coordinates and the orientation signals. The switch (400) also employs optic al alignment to precisely orient pairs deflectors (172) coupling a beam of ligh t (108) between optical fibers (106).

Title: Objets graphiques ayant des origines definies avec une elasticite
Inventor: HOLLINGSWORTH DAVID E
IPC: G06T11/60
Filed: 2000-07-19
Abstract: Pour traiter la disposition d'objets graphiques, des structures de données élastiques sont établies pour les objets graphiques, de manière à définir des tailles minimum et préférées, des propriétés d'étirage et des propriétés de compression. Les objets graphiques composés ont des propriétés élastiques calculées à partir de leurs composantes par des opérations d'addition et de maximisation qui dépendent des élasticités relatives des composantes. Les positions des origines à l'intérieur des objets graphiques sont définies par paires d'élastiques dans chacune des deux dimensions. La largeur par défaut ou la hauteur préférée d'un objet graphique peuvent être modifiées. Les élastiques de modification sont un mécanisme efficace permettant de modifier les caractéristiques d'affichage d'objets graphiques tout en préservant certaines relations d'affichage.

Inventor: ANDRIEVSKY ANDREI
IPC: C07D487/22
Filed: 1997-04-04
Abstract: The present invention provides calixpyrrole, calixpyridinopyrrole, and calixpyridine macrocycles, having 4, 5, 6, 7 or 8 heterocyclic rings, as well as syntheses, derivatives, conjugates, multimers, and solid supports thereof.  Such macrocycles have proved to be effective and selective ion- and neutral molecule-binding agents forming supramolecular ensembles, and ion- and neutral molecule-separation agents. The macrocycles are fully meso-non-hydrogen-substituted porphyrinogens, a few molecules of which were previously known but not recognized as possessing anion- or molecule-binding properties. The binding mode is noncovalent, primarily that of hydrogen-bonding, thereby providing a new mode for liquid chromatography, that of Hydrogen Bonding Liquid Chromatography. Further useful applications of the macrocyles provided herein include environmental remediation by removal of undesired ions or neutral molecules, and removal of phosphate for kidney dialysis.
