Title: Method and device for capturing and processing graphical information
Inventor: DEBUISSER THOMAS
IPC: G06F3/0354
Filed: 1993-11-17
Abstract: ABSTRACT        Ultrasound pulses are emitted by two emitters (12,   14)   carried   by   an   instrument   (10)   and substantially aligned with the tip of the instrument. Several  receivers  (62a,  ...,  62e)  occupy  determined positions with respect to the support (50) on which a trace is made with the tip of the instrument 80 that ultrasound pulses emitted from any point on the surface of the support are received by more than two receivers. The  times  of  propagation  of  the  ultrasound  pulses between each of the emitters and receivers are measured in order  to evaluate  the  coordinates  of  the vector defined by the positions of the two emitters and to deduce  therefrom  the  position  of  the  tip  of  the instrument on the support, and at least one of the two instrument orientation   cues   consisting   of   the inclination  of  the  longitudinal  direction  of  the instrument with respect to the support and the angular position  of  the  instrument  about  an  axis  making  a predetermined angle with respect to the support.  The pressure  exerted on  the  support by  the  tip  of  the instrument is moreover detected in such a way as to determine a stroke width cue dependent on at least one of the orientation and pressure cues, on a stroke width cue,  and  to  associate  with  a  cue  representing  the position  of  the  tip  of  the  instrument,   a  cue representing the stroke width for this position.

Title: Codage de signaux vocaux asymetrique pour systeme de communication cellulaire numerique
Inventor: CHUNG MIN I
IPC: H04B7/005
Filed: 1995-09-25
Abstract: Un système de communication cellulaire numérique est doté d'un codeur de paroles asymétrique pour améliorer la qualité audio dans le canal de la liaison ascendante. Un codeur de paroles à débit rapide est utilisé dans la liaison ascendante du système de communication cellulaire numérique pour améliorer la qualité audio. Pour compenser l'élargissement de la bande passante nécessité par ce codeur de paroles à débit élevé, la liaison ascendante utilise un code de canal, tel qu'un code convolutif, qui produit un moins grand nombre de symboles par bit d'entrée, ce qui nécessite une bande passante moins large. La baisse du gain de codage résultant de la modification dans le code convolutif est compensée par l'application d'une stratégie de contrôle de puissance spéciale. Cette stratégie de contrôle de puissance accroît la puissance d'émission des émetteurs-récepteurs utilisant le codeur de paroles asymétrique de l'invention.

Patent CA-2162862-A1 (CA)
Title: Leak detection assembly
Inventor: DAWSON GARY D
IPC: F02M25/08
Filed: 1994-05-16
Abstract: An assembly (12) for testing an evaporative emission control system (10) of an automotive vehicle which controls emission of volatile fuel vapors. The assembly is used to determine if a leak is present in a portion of the system which includes a vapor collection canister (14). The leak detection assembly incorporates a vacuum actuated canister vent control valve (32) which seals the evaporative system so the leak detection test can be performed. A vacuum actuated pump (28) performs a leak detection test. An engine control (26) initialize the pump by drawing air into a pump cavity and also closes the vent control valve (32). After the initialization period, the pump is activated to pressurized the evaporative emission control system. Once a control pressure is achieved, the cycle rate starts to drop off. If no leak, the pump will continue to pump at a rate that will be representative of the flow characteristics of the size of the leak. After the test has been concluded, the vent control valve (32) will unseal the system after the vacuum has been bled out through the orifice/check valve (31) that has been holding the seal during the test.

Patent CA-2164496-A1 (CA)
Title: Electrical circuit protection devices comprising conductive liquid compositions
Inventor: SHEA JOHN JOSEPH
IPC: H01H29/00
Filed: 1995-12-05
Abstract: The invention provides an electrical circuit protection device using a conductive liquid contained in a flexible tube contacted and sealed at each end by an annular metal electrode capped by a flexible membrane. The flexible tube is further sealed inside a solid insulating tube which contains a ferromagnetic liquid. The ferromagnetic liquid surrounds the flexible tube and remains in intimate contact with the outside of the flexible tube and is connected to a load sensing element which generates a magnetic field in the ferromagnetic fluid in response to excessive currents applied in the current path through the conductive liquid between the electrodes. This assembly is contained inside a tubular resistor. Under normal current conditions, a current flows through the conductive liquid which has relatively low resistivity. Upon a fault condition, a self generated magnetic field from the fault current causes the ferromagnetic fluid to rapidly constrict and pinch off current flow in the conductive liquid by constricting the current path in the liquid through deformation of the flexible capsule, i.e., by radial contraction and axial expansion. The current is then preferably commutated to the cylindrical resistor to limit the let through current to a safe value. Once the fault is limited, the magnetic field is dissipated and the flexible membranes force the conductive liquid and ferromagnetic fluid back to its their original position and the conductive liquid accordingly automatically reverts back to low resistivity for normal current conduction.

Title: An excess-flow safety shut-off device
Inventor: ESPLIN TREVOR THOMAS
IPC: F17C13/12
Filed: 1994-08-08
Abstract: A fluid flow safely device comprises a body having an inlet end for connection to a fluid supply and an inlet passageway (8, 48, 103) which leads lo a selective fluid flow sensor chamber (9, 49, 115) having a sealing means (10, 50) which encircles the outlet orifice (11, 51) of smaller cross section than that of the sensor chamber, said outlet orifice leading from the sensor chamber into a pressure chamber (12, 52) within the body leading to an outlet. Between the inlet end of the sensor chamber and the sealing means is a tapered section (13, 117), wherein the bore of the sensor chamber decreases in a diameter as it nears the sealing means. A sensor chamber shield (120) may encircle the sensor chamber by forming, defining and separating the internal length of the sensor chamber passageway from that of the inlet or any other passageway. A ball (16, 56, 119) in the sensor chamber moves between the inlet passageway end of the sensor chamber and the outlet orifice, to form a seal with the sealing means when flow through the sensor chamber is above a predetermined value. Within the pressure chamber is a movable piston (20, 60, 131) in sealing contact with it to increase or decrease the volume of the pressure chamber. Movement of the movable piston from a rest position fully towards the sensor chamber will deny a seal to be made between the ball and the sealing means. The movable piston may be a primary valve mechanism which forms a seal between the inlet and outlet passageways. The movable piston may include an indicator mark visible only when the pressure in the pressure chamber is above a predetermined value. Embodiments for LP gas include separate use of sensor chamber or movable piston with or without primary valve.

Title: Neurophysiologically designed knee orthosis with three dimensional joint
Inventor: BLEAU JEAN-CLAUDE
IPC: A61F5/01
Filed: 1996-02-13
Abstract: A physiologically designed improved knee orthosis in which the lateral and medial hinges are articulated asymmetrically. The improved knee orthosis has a thigh cuff with a medial portion, a lateral portion and an anterior portion, a shank cuff with a medial portion, a lateral portion and an anterior portion, a medial hinge for linking the medial portion of the thigh cuff to the medial portion of the shank cuff, a lateral hinge for linking the lateral portion of the thigh cuff to the lateral portion of the shank cuff, means to strap the thigh cuff to a wearer's thigh, and means to strap the shank cuff to a wearer's shank. The medial hinge, having a first variable axis of rotation, has a first pair of parallel, concentric spherical shells defining a first opening between them, fastened to the medial portion of the thigh cuff, and three rivets, forming a first equilateral triangle having a center coincident with the first variable axis of rotation, fastened to each shell. The medial hinge also has a first spherical shell designed to be inserted into the first opening, fastened to the medial portion of the shank cuff and three grooves to receive the three rivets. The lateral hinge, having a second variable axis of rotation, has a second pair of parallel, concentric spherical shells defining a second opening between the shells, fastened to the lateral portions of the thigh cuff, and three rivets, forming a second equilateral triangle having a center coincident with the second variable axis of rotation, fastened to each shell. The lateral hinge also has a second spherical shell designed to be inserted into the second opening, fastened to the lateral portion of the shank cuff and three grooves to receive the three rivets. The medial hinge and the lateral hinge have concavities opposite each other in order to account for the variable axis of rotation of the knee joint within the anatomical boundaries of the knee. In use, when the wearer's leg is extended, the first variable axis of rotation and the second variable axis of rotation are coincident and in alignment with the wearer's epicondyles, and when the wearer's leg flexes and extends, the first variable axis of rotation and the second axis of rotation are coincident throughout the range of motion, thereby accurately mimicking the instantaneous axis of rotation of the wearer's knee throughout flexion and extension, abduction and adduction and anterior/posterior translation. The improved knee orthosis is adjustable and has a slidable lower shin cuff to prevent migration of the orthosis along the wearer's leg.

Filed: 1994-08-24
Abstract: The present invention pertains to improved closure arrangements which are durable in con-struction, yet easy to open and reclose, and which provide an initial hermetic seal with tamper ev-idency, all utilizing a one-piece lid design. In two embodiments according to the present inven-tion, unique combinations of a mechanical inter-locking closure system (17, 26), heat-sealing or bonding (25), and a weakened failure zone (24) are employed in the vicinity of the lid/container juncture to achieve these desirable characteristics. In a third embodiment of the present invention, a mechanical interlocking and sealing arrangement is utilized to achieve hermetic sealing of the con-tainer without the need for a heat seal or bonded region, and a weakened failure zone is located just inward of the mechanical interlocking con-nection. With all embodiments according to the present invention, upon tearing the lid open the lid forms a recloseable plug-fit closure to reclose the container, while the rim of the lid once re-mains attached to the container in its initial po-sition. The resulting container is extraordinarily simple in construction, rendering it easy and cost effective to produce, yet providing superior per-formance both in maintaining the initial freshness of the product and in providing ease of consumer operation.
Patent CA-2171484-A1 (CA)
Title: Digital remote scaling
Inventor: STRONG WARREN ERIC
IPC: G01B11/28
Filed: 1996-05-07
Abstract: In traditional roundwood scaling methods a truck load of wood is measured by physically measuring the length, width and height of the truck. Then the scaler calculates the area of the measured load. After deductions for loose piling, defects etc. the area or volume is converted to dimensions such as cords or cubic meters morecommonly known in the industry. There is continuously a battle by companies to determine how much fibre they are buying fibre. For instance a truck load of small diameter wood has much less solid wood fibre then a truck load of large diameterwood. Off loading a truck and measuring each piece of wood is to expensive so averaging is the norm with factors for converting stacked volumes to solid volumes.   In this invention, called digital remote scaling (DRS), digital cameras, computers and existing or customized software are combined to help solve these problems. The scaler sits in an office where digital camera's supply images of the truck(i.e. sides and top) to a computer screen. The cameras are located at pre determined distances from the truck. The truck stops in the same position each time. With some calibration the image on the computer screen can be scaled exactly to the actual size of the truck. Standard software or custom software can measure the area of wood on the truck. From that point an average section can be selected by the scaler and the size of each piece of wood measured very easily on the computer screen or the image can be printed in colour or grayscale and measured. This will provide speed with accuracy of scaling and particularly speed with accuracy of solid wood content unheard of in the industry.   These digital images provide picture records that can be used to compare tree size to cutting areas and manipulated to consider other factors of interest to companies. One of the most important factors is that it will cut scaling costs subtaintially and provide accurate estimates for total solid inventories in sawmills and paper companies. As well as economically retaining records of deliveries.
Patent CA-2173317-A1 (CA)
Title: Pharmaceutically acceptable polymeric tissue coating
Inventor: HUBBELL JEFFREY A
IPC: C08G63/91
Filed: 1994-10-05
Abstract: Described herein is a multi-functional polymeric material for use in inhibiting adhesion and immune recognition between cells and cells, cells and tissues, and tissues and tissues. One component of the polymeric material adsorbs well to cells or tissue, and the other component of the polymeric material does not adsorb well to tissues. A water-soluble polymer that does not bear charge (polynonion) and which is not poly(ethylene glycol) is used as the non-binding component. A water-soluble polymer that is positively charged at physiological pH (polycation) and which is not poly(L-lysine) is used as the tissue binding component. When the bi-functional polymeric material contacts a tissue, the tissue-binding component binds and thus immobilizes the attached non-binding component, which will then extend generally away from the tissue surface and sterically block the attachment of other tissues. The method and compositions are useful in inhibiting formation of post-surgical adhesions, protecting damaged blood vessels from thrombosis and restenosis, and decreasing the extent of metastasis of attachment-dependent tumor cells.
