Title: Security access control system enabling automatic invalidation of stolen or lost electronic keys and/or transfer of authorisation to make keys
Inventor: GUERIN DIDIER
IPC: G07C9/00
Filed: 1997-04-15
Abstract: A security access control system comprises a portable storage medium (C) on which is registered an electronic key (CL) including user identification data, the key being provided by a production means (LE), and a means ensuring an electronic locking function (L) to authorise access when the storage medium comprises the required electronic key. According to the invention, a logic key (CL) comprises its own data D¿P?A and its signature S and is registered in the lock (L) when it is first used. When a user loses the medium (C) on which is registered this key (CL), a new key (CL') is registered on another medium and the registration of this new key in the lock overwrites the previous key (CL). To transfer authorisation to make new keys (CL) from one production means (LE) to another, a new public key (K') and the signature (CER) of this key are loaded into it. This invention is useful in the management of buildings.

Patent CA-2258927-A1 (CA)
Inventor: DAMASSE JEAN-MICHEL
IPC: C25D7/00
Filed: 1997-06-26
Abstract: The invention concerns an element of a continuous metal casting ingot mould with a copper or copper alloy cooled wall to be contacted with liquid metal and comprising on its external surface a metal coating, characterised in that the said coating consists of a silver plating. In a preferred embodiment, this wall is a cylinder hoop for a continuous casting machine of thin metal strips between two cylinders or on one single cylinder. The invention also concerns a method for coating with a metal plating the external surface of a copper or copper alloy cooled wall of an element of a continuous metal casting ingot mould, characterised in that a coating is effected by the deposit of a silver plating on said surface preferably by electrolysis. Preferably, the restoration of said silver plating is done by allowing a residual silver plating to subsist on said wall, and by effecting a re-silvering of said plating by placing said wall in cathode in an electrolysis consisting, for instance, of an aqueous silver cyanide solution, of an alkaline metal cyanide and of an alkaline metal carbonate.
Patent CA-2259880-A1 (CA)
Title: Broadcast coupler
Inventor: STENGEL FRANCIS A JR
IPC: H04B1/52
Filed: 1999-01-22
Abstract: A broadcast coupler which couples both a broadcast radio receiver and communications equipment in a vehicle to the existing OHM vehicle antenna wherein no physical modifications are made to either the antenna mast or the antenna base or the antenna feed line. The broadcast coupler has a built-in tuner capability which permits the existing OEM supplied antenna to function as a low standing wave ratio (SAR) communications antenna. The broadcast coupler tunes the existing OEM antenna and provides the necessary isolation to permit the communications equipment, i,e, transmitter, receiver or transceiver, to function without detection by the operation of the vehicle. Since the existing OEM antenna is tuned by the broadcast coupler, the vehicle does not have to be modified and a new antenna does not ave to be purchased.
Patent CA-2260791-A1 (CA)

Title: Colmatage d'un jeu entre un conduit de reception et un conduit de chemisage
Inventor: STEPHENSON ADAM JOHN
IPC: F16L55/16
Filed: 1997-07-30
Abstract: L'appareil selon l'invention permet de colmater un jeu existant entre un conduit de réception (2) et un conduit de chemisage (1), celui-ci venant, en utilisation, s'insérer dans celui-là. Cet appareil comporte un élément tubulaire (3), destiné à se raccorder au conduit de chemisage ou bien à en constituer l'extrémité antérieure, ainsi qu'un joint compressible (6), conçu pour s'allonger sur un plan radial lorsqu'il est comprimé dans le sens de la longueur et qui, en utilisation, est monté sur l'élément tubulaire. Un tel agencement fait que le joint se déplace librement avec l'élément dans le sens de la progression du conduit de chemisage mais que ce mouvement cesse lorsque le conduit de chemisage se retire dans la direction opposée; le joint, qui est alors comprimé dans le sens de la longueur par ledit élément, s'allonge sur un plan radial pour venir au contact de la paroi intérieure du conduit de réception et, partant, colmater le jeu.

Patent CA-2263119-A1 (CA)
Inventor: BICER DEMETRIO
IPC: A61F2/24
Filed: 1997-08-06
Abstract: A bileaflet prosthetic valve has leaflet pivots symmetrically or centrically located, thereby providing a central opening about twice the size of the two lateral openings. The valve opens from the center outward to provide nonturbulent central flow. The laminar leaflets are curved in cross section so that the downstream edges of the leaflets are closer to the centerline of the cylindrical support ring when the leaflets are in an opened configuration. This position dispose the leaflets to favor valve closure when reverse flow of blood occurs. As the leaflets move toward a closed position, upstream edges of the leaflets begin to close the lateral openings, but this movement is opposed by blood flowing through these openings thereby providing a force to decelerate the leaflets and cushion their final closing. When the valve is fully closed, a single point of conflict between the upstream edge of each leaflet and the support ring leaves a small gap between the support ring and the rest of the upstream edge and prevents the downstream edges from touching each other when they close the central opening.

Patent CA-2278235-A1 (CA)
Inventor: VAUGHAN KENNETH F
IPC: H04M3/30
Filed: 1998-06-03
Abstract: A standalone telephone line status monitoring and reporting devi ce (10) for use between a subscriber's premises loop and the local telephone network is disclosed. The device operates on loop current, external AC or DC power from the subscriber's premises, or internal battery (61). The device passively monitors the status of the premises loop until an alarm condition is detected.  When premises communications equipment is on-hook or off-hook, the device detects normal Tip-Ring voltage and current conditions. If an open circuit, short circuit, or invalid loop impedance condition is detected, the device indicates a potential fault in the premises wiring. The device then reports the alarm either by visual or audible indications (11), electronically to an external monitoring device, or by auto-dialing one of two preprogrammed telephone numbers. The fault may be reported over wireline telephone line or radio link (21) to the central office or other location. Additionally, when configured for radio link communications with the central office, the device may be remotely reset.

Title: Restricted mobility area
Inventor: RUNE JOHAN
IPC: H04W12/08
Filed: 1998-01-30
Abstract: The present invention relates generally to dividing a cellular mobile communications system into general geographic areas. The cellular system is logically divided into an access provider, having knowledge of and controlling access to the system over the air interface, and a core service provider having subscribers and providing services to those subscribers over the bearer services provided by the access provider. The core service provider chooses some general area within which a particular service is to be provided or within which access is to be restricted. This information is transmitted to the access provider who then maps this information onto the cellular system, thereby determining which cells within the network lie within the area designated by the core service provider.
Patent CA-2281362-A1 (CA)
Title: Zero cross relay actuation method and system implementing same
Inventor: JENSKI LEONARD
IPC: H01H47/00
Filed: 1999-09-02
Abstract: Disclosed is an electromechanical relay drive system which prolongs relay life by ensuring operation of the relay in a manner to make and break contact between the contact electrodes at a zero crossing point of the switched waveform. Relay aging and environmental variations are dynamically compensated upon each actuation of the electromechanical relay to ensure proper timing of the energization and de-energization of the relay to ensure switching at the zero crossing point. Additionally, the drive system described compensates for variations in the actual contact operation during actuation for the positive and negative half cycle of the switched waveform. Furthermore, the system of the instant invention alternately energizes and de-energizes the electromechanical relay during the positive and negative half cycles of the switched waveform to prevent metal deposition from one contact electrode to the other. This system calculates the appropriate delays on a dynamic historical perspective by sensing slope changes of the coil voltage and current.
