Patent CA-2273779-A1 (CA)
Title: A control architecture using a multi-layer embedded signal status protocol
Inventor: LANDRY JOSEPH ELIDE
IPC: H04L12/56
Filed: 1999-06-09
Abstract: Distributed switch fabrics can support multiple switching functions while meeting established performance requirements by using a control architecture based on multiple layers of signal status carried within signals transported through the distributed switch fabrics. More specifically, a method and apparatus is provided for controlling the selection of signals through distributed switch fabrics by deriving signal status information for the signals at any point along a transmission path and embedding the signal status information in each of the signals using multiple signal status layers. Each of the signals carries its respective signal status information as it propagates along the transmission path, so that the embedded signal status information can be selectively extracted from any of the multiple signal status layers to facilitate a selection decision at any of the distributed switch fabrics. The multiple layers of signal status can be used to provide a cumulative signal status of a particular signal as it propagates along the transmission path or the multiple layers can be used to support various combinations of status control, such as each layer being used to track a different level or type of status for the signal.

Patent CA-2280261-A1 (CA)
Inventor: PETTY NORMAN W
IPC: H04L12/56
Filed: 1999-08-11
Abstract: In an asynchronous transfer mode (ATM) disassembler unit that is receiving ATM cells from an optical interface and converting data from these cells onto a constant bit rate (CBR) call, only a nominal predefined build out is defined for each optical interface. If an ATM cell is not received within the proper amount of time for the CBR call from the optical interface, the build out is automatically adjusted so that the build out is equal to the amount of delay that was experienced in receiving the next ATM cell for the call. Only the build out for the individual call that actually experienced the delay of the ATM cell is redefined. The other calls being handled by the optical interface are not effected by this automatic adjustment of the build out interval for the individual call. In addition, when an ATM cell is delayed for a particular call, the information that is transmitted for the call is the last PCM sample of the present ATM cell for that call.  This requires in the case of a wideband call that consists of a frame subdivided into a plurality of channels that the frame must be repeated upon an ATM cell being delayed. When the delayed ATM cell is received, all PCM samples for the call are transmitted so that no PCM samples are discarded.

Patent CA-2290697-A1 (CA)
Inventor: SANDBERG THOMAS
IPC: B65D81/26
Filed: 1999-03-12
Abstract: Packaging for volatile, heat-sensitive products, said packaging eliminating all dangerous effects of chance ignition during transport and storage by enabling control of the order in which the various packed components disintegrate when the packaging is exposed to external fire. A sample application for the packaging is the packing of airbag modules: the airbag can be rendered harmless by decomposing (under the influence of heat) before the gas generator ignites. The volatile, heat sensitive component (3) which is to be protected is placed in a thermally insulating material (5) while the insensitive component is left unprotected. Both the product (1) and the thermally insulating bed (5) are placed in a protective container (4). Gases are vented from the purpose-designed and dimensioned protective container (4) after they have escaped via the openings (7). This prevents randomly acting gases giving rise to unidirectional, reaction forces.
Patent CA-2290899-A1 (CA)
Inventor: BERUBE CLAUDE
IPC: G09F15/00
Filed: 1999-12-02
Abstract: Les supports à pictogramme utilisés actuellement sont inadéquats car, de construction rudimentaire, ils sont difficiles à manipuler par temps froid avec des mitaines. De plus, ils sont en pièces détachées, ce qui augmente l'espace requis pour l'entreposage et le nombre d'étapes d'installation (installation du support-recherche du pictogramme approprié-installation dudit pictogramme sur ledit support).  Enfin, les composantes desdits appareils actuels rouillent au contact du sel et calcium ce qui rend la tâche encore plus difficile à l'utilisateur. La présente invention remédie à tous ces inconvénients en reliant les composantes ensemble pour faire un appareil mono-pièce, par l'utilisation de mécanismes plus simples, en utilisant des composantes anti-corrosives et en identifiant le genre de pictogramme incorporé dans l'appareil sur celui-ci.

Patent CA-2294548-A1 (CA)
Title: Pyridazinones as prostaglandin endoperoxide h synthase biosynthesis inhibitors
Inventor: BLACK LAWRENCE A
IPC: A61P29/00
Filed: 1998-08-20
Abstract: The present invention describes pyridazinone compounds which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX-2). COX-2 is the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important "housekeeping" enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectivity of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti-inflammatory drugs (NSAIDs).
Patent CA-2296510-A1 (CA)
Inventor: SUTIN ALEXANDER M
IPC: F41H11/12
Filed: 1998-07-15
Abstract: A device (10) which employs an acoustic signal having one or more frequencies for penetrating into ground, water, or sediments and vibrating a compliant buried object (8) is provided. When these acoustic signals encounter an acoustically compliant object (8) such as a mine, the acoustic signals vibrate the compliant object (8), leading to a vibration of the compliant object (8) against the boundaries of the surrounding medium such as ground sediment, creating a nonlinear distortion of the probing signal including the generation of harmonics and acoustic waves with combination frequencies (nonlinear signals). These nonlinear vibrating signals are received from the surface by a sensor (20). The amplitude of the measured nonlinear signals indicates the presence of an acoustically compliant object (8) such as a mine. The present invention also relates to a method and apparatus which emits an electromagnetic RF probing signal and acoustic or vibration signal (modulating signal), detects the reflected electromagnetic signal from the buried object (8), and processes the received signal, identifying the modulation caused by vibration.
