Patent CA-2373778-A1 (CA)
Title: Broadcast transmission system with distributed correction
Inventor: TWITCHELL EDWIN RAY
IPC: H04L27/36
Filed: 2000-05-12
Abstract: A transmission system (14) broadcasts an information signal. Within the system (14), several components (e.g., 20-24) cause distortion to the information signal as the signal is processed and proceeds toward a broadcast antenna. The group of distortion causing components (20-24) is identified as a first group, and is arranged in a sequence along a signal path (12) toward the antenna. The first group of components (20-24) performs various functions, including amplification, but each subjects the information signal to distortion shifts away from intended values. A second group of components (e.g., 28-32) modifies the information signal to compensate for the distortion shifts imposed by the first group of components (20-24). The second group of components (28-32) is located upstream of the first group of components (20-24). The second group of components (28-32) is arranged in a sequence to modify the information signal to compensate for the distortions in an order inverse to the occurrence of the distortions.

Title: Adhesif microencapsule in situ
Inventor: SCHWANTES TODD ARLIN
IPC: C08F285/00
Filed: 2001-08-30
Abstract: L'invention concerne un nouvel adhésif formé in situ dans une microcapsule et un procédé permettant de former un tel adhésif auto-collant ou fluide in situ dans une microcapsule. Le procédé permettant de former ce nouvel adhésif consiste à fournir un mélange aqueux d'un matériau constituant d'un mur dans de l'eau; à ajouter au mélange aqueux, un matériau de coeur sensiblement insoluble dans l'eau, un initiateur à radical libre, et un solvant pour les pré-polymères. Le matériau de coeur comprend un premier pré-polymère d'addition polymérisable présentant une Tg inférieure à environ 0 ·C, un point d'éclair d'au moins 75 ·C, et un point d'ébullition d'au moins 175 ·C. Ils sont généralement choisis dans le groupe comprenant des matériaux de type acrylate ou méthacrylate. Eventuellement, un second pré-polymère d'addition polymérisable est ajouté afin d'obtenir la réticulation ou interaction entre les chaînes polymères. Une agitation par cisaillement élevée est appliquée au mélange aqueux de manière à obtenir une taille particulaire d'environ 0,1 à 250 microns. Le brassage à une première température déclenche la formation de la paroi de la capsule; et le chauffage à une seconde température permet de polymériser les pré-polymères du matériau de coeur de manière à former un adhésif in situ dans les capsules formées.
Patent CA-2385532-A1 (CA)
Inventor: JACOBSON DALE CONRAD
IPC: G02B6/13
Filed: 2002-05-08
Abstract: A method of etching a ferrolectric material is disclosed whereby a single layer of ions is implanted into a surface of the film and then, without first annealing the substrate, the material between that surface and the layer of ion implantation is etched away. Such a method has the benefit of being faster and much less costly as compared to prior art methods. A single ion implantation of sufficient energy causes a high level of electronic damage near the surface of the material and a high level of crystalline damage at the ion implant level. While it is well known that crystalline damage greatly increases the etch rate of a ferroelectric material, the inventors have discovered that the aforementioned electronic damage also substantially increases the etch rate of the material. Since damaged lithium niobate etches at a much faster rate then undamaged lithium niobate, no annealing is necessary to create an etch stop. Additionally, since there is sufficient damage, either electronic or nuclear, continuously from the surface of the material to the implant layer, multiple ion layer implantations are not necessary.

Inventor: EZAKI TAKAYUKI
IPC: G01N33/53
Filed: 2002-06-19
Abstract: A method for testing whether or not an antibody that binds with any of a plurality of target antigens is contained in a test sample. In this method, a test sample is contacted with an antigen microarray having spots of at least eight types of target antigens. In the case the test sample contains an antibody corresponding to the target antigens, that antibody is retained on the antigen microarray by an antigen-antibody reaction. A labeled secondary antibody labeled with a fluorescent pigment is then contacted with the antigen microarray. Fluorescence of the labeled secondary antibody is then detected by a detection device such as a laser fluorescent microscope or laser scanner.

IPC: H03M13/41
Filed: 2001-03-30
Abstract: L'invention concerne un procédé et un dispositif destinés à améliorer le rendement d'un codeur convolutionnel utilisé dans un système de communication à mode crénelé. Dans un système de communication à mode crénelé classique, un flot de symboles codés de manière continue et convolutionnelle est transmis par l'intermédiaire d'une station de base. Une unité à distance comprenant un décodeur convolutionnel capable de décoder ce flot de symboles circule entre des états actif et inactif. Lorsqu'elle se trouve dans un état actif, ladite unité à distance manque une partie du flot continu de symboles. Après l'interruption de ce flot de symboles, les métriques d'état d'un treillis à l'intérieur du décodeur son initialisées. L'initialisation des métriques d'état peut impliquer la polarisation du processus de décodage vers des états valides uniquement, par opposition aux états invalides. En outre, cette initialisation peut impliquer une absence de polarisation vers un état particulier à l'intérieur de ce treillis.
