Title: Video conference system with atm cell reuse
Inventor: HORIUCHI EDWARD M
IPC: H04L12/28
Filed: 1998-05-19
Abstract: A multipoint video conferencing system in which the video conferencing terminals are in a daisy-chain arrangement with the head-of-chain terminal connected to the ATM network. ATM cells are relayed from the ATM network downstream to the last terminal, and from each terminal upstream to the network. Each video conference terminal has a video program input port provisioned with a unique ATM address, and a plurality of video program out ports, each provisioned with one of the video program input port addresses. ATM cells generated from each video program input port are transmitted upstream to the ATM network where they are relayed back to the head-of-chain terminal and then downstream to the last terminal.      Each video conferencing terminal may also receive ATM cells having addresses that match the addresses provisioned for its video program output ports. These cells are converted to analog video programs and transmitted out the associated video output ports. In this manner, an ATM cell may be used on several video conferencing terminals.

Patent CA-2261607-A1 (CA)
Inventor: PANDE RAJIV
IPC: C12Q1/68
Filed: 1997-07-16
Abstract: La présente invention concerne un procédé, un kit et une composition de réactif destinés à déterminer la présence d'un acide nucléique cible dans un échantillon, ceci se faisant par réaction cyclique à deux étapes de la cible. Au cours de la première étape de la réaction, l'acide nucléique cible s'hybride avec un acide nucléique sonde pour libérer un activateur dans le milieu du dosage. Au cours de la deuxième étape de la réaction, un complexe analogue de cible-fixateur est clivé par l'activateur, qui accomplit la double fonction de libérer l'analogue de cible dans le milieu du dosage et de lancer l'émission de signaux. L'analogue de cible libéré relance ensuite la réaction cyclique par liaison à une deuxième sonde, qui libère un deuxième activateur, et ainsi de suite. Cette réaction cyclique entraîne une augmentation des signaux émis dans un échantillon à partir d'une seule molécule d'acide nucléique cible, ce qui permet d'améliorer grandement le degré de détection de la cible auquel on peut s'attendre.

Patent CA-2273455-A1 (CA)
Title: Decorative plant cover
Inventor: POSA JOHN G
IPC: A01G13/02
Filed: 1999-06-02
Abstract: A sheet of material exhibiting a decorative floral pattern is used as a protective plant covering in conjunction with a plurality of removable fasteners. The sheet has a peripheral edge preferably defining an area sized to permit wrapping of the sheet in full, uncut form around a single, larger plant, or cutting of the sheet into multiple pieces to wrap a plurality of smaller plants on an individual basis. A non-woven material may be used so that it will not unravel if cut into sections. The material may also be at least semi-transparent to permit floral features of the plant to show through so that the material is less conspicuous when installed. Preferably a design element defining a cell is used having an area substantially less than that of the sheet, which is then replicated in a repeating manner to permit slitting, sectioning, and installation without regard for the orientation of the design. To assist the installed sheet in appearing more visually convincing, a process of producing the final product may include the steps of generating an image of a living plant, converting the image into a form suitable for printing, and printing the converted image onto the sheet.      To correct for compression of the image on either side when the sheet is wrapped around a plant, the aspect ratio of the image may be adjusted so that the printed image appears more life-like when the sheet is wrapped around the plant.

Patent CA-2277252-A1 (CA)
Inventor: HOST-MADSEN ANDERS
IPC: H04Q7/36
Filed: 1999-07-09
Abstract: We consider the problem of multi-user detection for CDMA systems where the codes of some users are known while others are unknown, semi-blind multi-user detection. An example is at the base station of a cellular communication system with interference from both in-cell users, with known codes, and out-of cell users, with unknown codes. In this paper we develop a number of semi-blind multi-user detectors using a subspace approach. One class of detectors developed has a computationally efficient structure of a subspace estimation common to all known users, followed by a simple processing specific to each user. The performance of the detectors is compared to that of the purely blind detector and the non-blind detector, and the semi-blind detectors are seen to have the best performance.
