Patent CA-2239988-A1 (CA)
Inventor: WATERHOUSE PAUL
IPC: G01N21/64
Filed: 1996-12-12
Abstract: Des supports pour gels pour électrophorèse font appel à des fibres enrobées, en particulier des fibres de verre, servant d'éléments d'espacement entre les substrats. Plusieurs fibres avec un noyau interne à point de fusion élevé et un enrobage externe à point de fusion bas sont placées entre des premier et second substrats plats. Les fibres sont chauffées à une température suffisante pour ramollir au moins l'enrobage externe des fibres sans ramollir le noyau interne des fibres. Le tout est ensuite refroidi en maintenant le contact avec les premier et second substrats, pour resolidifier l'enrobage externe. Ceci fait adhérer les fibres aux premier et second substrats et on forme ainsi une chambre pour gel entre les premier et second susbtrats. La chambre pour gel a une hauteur définie par le noyau interne des fibres. Les fibres peuvent être chauffées avant ou après avoir placé le second substrat sur les fibres. Les supports pour gel formés peuvent être remplis immédiatement avec une solution formant un gel tel qu'un polyacrylamide, ou ils peuvent être conservés aussi longtemps que nécessaire, en attente d'utilisation.

Title: Optical filter fabrication method and apparatus, optical filter, fiber holder with spiral groove, and phase mask
Inventor: TERAO YOSHITAKA
IPC: G02B6/36
Filed: 1998-07-06
Abstract: An optical filter is manufactured by placing a photosensitive optical fiber in a spiral arrangement on a fiber holder, preferably having a spiral groove for holding the fiber, and exposing the fiber to ultraviolet light through a phase mask having a spiral diffraction grating, forming an in-fiber Bragg grating.  The fiber can be conveniently scanned by an ultraviolet beam as the fiber holder and phase mask turn on a rotating stage.  The fiber can be compactly packaged between the fiber holder and a cover.  The fiber holder and cover can be formed by coating a substrate with layers of polymer material, the spiral groove being formed by photolithographic patterning of one of the layers.

Patent CA-2267079-A1 (CA)
Inventor: SYDAENMAA MATTI
IPC: G10L19/005
Filed: 1997-09-26
Abstract: A digital audio receiver stores received frames temporarily for decoding and error concealment. A reconstructing block (14) in the decoder reads stored frames using a read window (43) wherein the latest received frame (+cnnxt) is undecoded. Decoding is carried out in stages so that the correctness of the current frame (0) is examined and possible errors are concealed using corresponding data of other frames in the window. Detection of errors is based on checksums (19, 26) and allowed values of bit combinations in certain parts of the frame. In addition, the receiver maintains an estimate (60) for the signal's bit error ratio and uses it to control the operation of the error concealment algorithm.

Patent CA-2268711-A1 (CA)
Inventor: ANDERSON EILIF J
IPC: A01B1/16
Filed: 1999-04-07
Abstract: This invention is a manually-operated tool designed to remove the weeds between the rows of seeded plants in the garden. A T-bar handle and fork assembly make it easy to roll the metal drum over the ground while a spring steel blade sliding along just underneath the surface of the soil loosens the weeds. The drum acts as a depth control and the rods are slanted to perform a scissor- like action that leaves the weeds above ground where they can be easily raked up and deposited on the compost pile. At the same time the ROTOWEEDER breaks up any hard clods in the soil.

Title: Methods for identifying nucleic acid sequences encoding agents that affect cellular phenotypes
Inventor: KAMB CARL ALEXANDER
IPC: C12Q1/68
Filed: 1998-02-27
Abstract: Methods for identifying nucleic acid sequences that affect a cellular phenotype are disclosed. The method uses a reporter gene whose level of expression correlates with the phenotype in conjunction with a method or device for measuring the level of reporter expression. An expression library is introduced into the cells, and those cells exhibiting changes in reporter expression level are selected. Expression library inserts from the selected cells are isolated, thereby providing a sub-library enriched for sequences that affect the phenotype reflected by the reporter. Further rounds of sub-library introduction and cell selection may be carried out to provide additional enrichment. Sequences identified using this method may be used to ascertain the identity of additional molecules involved in generating the cellular phenotype.

Abstract: Dans un système de télévision numérique à satellite, dans lequel un téléviseur reçoit le signal via un récepteur/décodeur, tel qu'un boîtier décodeur, des application interactives peuvent être téléchargées et exécutées sur le récepteur/décodeur. Le code d'application est arrangé en modules, et le téléchargement des modules est précédé d'une recherche dans le module répertoire, à l'intérieur d'une adresse locale spécifique. Les modules sont signés et le module répertoire est signé et chiffré de telle manière qu'un seul chiffrement concerne la totalité des modules formant l'application. Des clés de chiffrement multiples publiques sont mémorisées dans la mémoire ROM du récepteur/décodeur. Ainsi les applications peuvent être créées par différentes sources, sans que ces sources aient besoin de connaître les clés de chiffrement privées des autres. Une fonction permet de mémoriser temporairement une clé de chiffrement dans la mémoire RAM du récepteur/décodeur pour permettre à un fabricant de récepteur/décodeur de vérifier son fonctionnement. Une signature du répertoire peut être cachée à une position variable à l'intérieur d'un bloc de fausses données dans le module répertoire. Une application devant être téléchargée peut être vérifiée au moyen d'une table de bits de validation d'application mémorisée dans le récepteur/décodeur.
