Title: Vcsel a cristal photonique monomode
Inventor: BIRKEDAL DAN
IPC: H01S5/183
Filed: 2005-11-29
Granted: 2015-01-27
Abstract: L'invention concerne un dispositif VCSEL (laser à cavité verticale et à émission par la surface) présentant une sortie monomode et, facultativement, une sortie à polarisation unique. Le dispositif est obtenu par confinement en mode latéral par effet PBG (largeur de bande interdite photonique) créé par gravure superficielle dans un miroir supérieur d'un VCSEL partiel. La zone PBG entoure une région MS (région de mise en forme de mode) caractérisée par des pertes élevées en mode longitudinal. La région MS entoure la région LA (région d'ouverture lumineuse) caractérisée par de faibles pertes en mode longitudinal. La région MS ne contribue pas au confinement en mode latéral relativement à l'ouverture LA et aux modes latéraux confinés par la zone PBG. Le VCSEL est ainsi optimisé pour un fonctionnement en un seul mode fondamental.

Title: Biological surgical patch prepared from animal tissue
Inventor: XU GUOFENG
IPC: A61L31/12
Filed: 2006-12-15
Granted: 2012-02-14
Abstract: Disclosed herein is a biological surgical patch having minimal immune rejection with good biocompatibility, along with safe/reliable application thereof, and a method of preparation thereof.  The biological surgical patch comprises a substrate prepared from a natural animal tissue; the patch is made by a method that includes the steps of crosslinking and fixing the substrate, minimizing antigens from the substrate, tanning the substrate, and incorporating an active layer in the substrate.  Cross-linking and fixing may be accomplished by using an epoxy compound that has a hydrocarbon backbone, that is water-soluble, and which does not contain an ether or ester linkage in its backbone.  Reagents are used to block specific active groups in protein molecules of the substrate, in order to minimize the antigens therein. Tanning is achieved preferably by grafting polymers onto collagen molecules of the substrate. The active layer preferably comprises a polypeptide or glycosaminoglycan.
Patent CA-2638042-C (CA)
Title: Aircraft wing
Inventor: DODD DANIEL
IPC: B64C3/50
Filed: 2007-02-07
Granted: 2014-09-16
Abstract: The part of a wing on which a slat is mounted tends to be significantly recessed to accommodate the slat. The spanwise extent of a leading-edge slat is often therefore restricted due to, for example, the presence of other structural elements which cannot accommodate such a recess, or by the need to house aircraft systems which can require significant storage space in the region of the wing leading-edge. An aircraft wing comprises a leading-edge slat, the slat including a main body portion and a slat extension arranged at a spanwise end of the main body portion. The cross-sectional area of the slat extension is less than the cross-sectional area of the main body portion. The slat extension may therefore provide some of the aerodynamic benefits of the slat, whilst enabling the volume of the leading-edge of the wing on which the slat is mounted, to be relatively large.
