Patent CA-2258286-A1 (CA)
Inventor: CHEN JIANPING
IPC: A61K38/00
Filed: 1997-06-10
Abstract: A method of preparing polyphosphazene microspheres wherein the polyphosphazene microspheres are produced by coacervation. In one embodiment, a solution containing a polyphosphazene is admixed with a dehydration agent, such as a solution containing a salt of a monovalent ion such as a salt of a Group I element (such as, for example, NaCl) to form a dispersion containing polyphosphazene coacervate microdroplets. The dispersion then is admixed with a solution containing a salt of a multivalent ion, such as a salt of a Group II element (such as, for example, CaCl2) to form a suspension of polyphosphazene microspheres. The polyphosphazene microspheres then are recovered from the suspension. Such method enables one to obtain high yields of microspheres having a controlled size distribution.

IPC: G07C15/00
Filed: 1997-09-26
Abstract: In order to validate a bet, a housing identifier and a validating datum representative of a reserve of available game units are stored in a file (MMP) of a main validating device (DVP). When the betting data are introduced by the player in the housing (BO), a restitution information containing these betting data as well as the housing identifier is constituted and this information is restored in sound form to a telephone station (PT). The corresponding telephone signal is then transmitted to a voice server (SV) which restores the data introduced by the player in decrypted form. The game units corresponding to the betting data received are then compared with the reserve of game units, for validating or not validating the bet. Thus there is no transmission of any indication concerning an effective payment for the bet by the telephone line between the housing (BO) and the voice server (SV).

Patent CA-2272918-A1 (CA)
Inventor: ELGIN RICHARD L
IPC: G06Q10/00
Filed: 1997-11-26
Abstract: A method is provided for maintaining components subject to fatigue failure during in service use. The method uses statistical distributions (10) in a simulation of in service use (16) of a fleet of components to predict the failure rate (12) of the fleet over a fixed time increment (14, 26) for an assumed inspection program. These predictions are used to determine an operating plan (20), including an inspection program, that will maintain an acceptable failure rate by detecting components with fatigue indications and removing the components prior to failure (22). The inspection program provides actual fatigue data resulting from in service use (18). As the inspection data base grows, the simulation is revised (24, 48) to incorporate the data. The predicted failure rates and the operating plan (20) are then updated based on the revised simulation.

Title: Waterproof outer garment
Inventor: HARRIGAN CHARLES M JR
IPC: A41D1/08
Filed: 1999-08-30
Abstract: A waterproof outer garment comprises one piece of material wrappable around the wearer between the knees and the back, with edges overlapping and securable to one another by quick locking and quick release fasteners. The edges are securable in varying amounts of overlap to adjust the garment to the size of the wearer, and suspenders prevent the garment slipping down on the wearer. In one embodiment, the entire garment is made from a material impervious to the ingress of water. In another embodiment, portions of the garment which are not subject to contact under pressure with snow and water are made of a lighter weight material which need not be waterproof. Garments according to the present invention which are made partly from non-waterproof material can be made lighter, more comfortable and perhaps more stylish than garments made entirely from waterproof material.

Abstract: The present invention relates to a novel gene, CaSm, that is highly expressed in cancer tissues and cell lines, especially pancreatic cancer. The full length cDNA of CaSm encodes a protein of 133 amino acids. CaSm contains the two Sm motifs found in the common snRNP proteins, with the greatest homology to the Sm G protein (60 % similarity). The present invention further encompasses CaSm peptides, fusion proteins, host cell expression systems, antibodies to CaSm, antisense CaSM molecules, and compounds that modulate CaSm gene expression or CaSm activity. Antisense CaSm RNA is able to alter the transformed phenotype of pancreatic cancer cells by reducing their ability to form large colonies in soft agar when compared to untransfected cells. The present invention also encompasses methods for disease diagnosis, drug screening and the treatment of cancer.

Abstract: On décrit un système et des procédés pour intégrer ou coder des données numériques dans un signal analogique hôte ou de recouvrement. Une caractéristique de signal distribuée du signal de recouvrement dans un domaine particulier (temps, fréquence ou espace) est calculée et comparée avec une série de valeurs de quantification préétablies correspondant à un symbole d'information à coder. Le nombre de changements nécessaires pour modifier la caractéristique de signal relativement à la valeur de quantification cible déterminée est calculé et le signal de recouvrement est modifié en conséquence pour ainsi modifier la valeur de la caractéristique dans un intervalle de temps préétabli. Des symboles d'information sont extraits par la mise en oeuvre du processus opposé.

Title: Commutateur multidiffusion
Inventor: HAGGERTY WILLIAM T
IPC: H04L12/18
Filed: 1998-04-14
Abstract: L'invention concerne un procédé et un appareil permettant d'établir des liaisons dans un réseau de communications commuté destiné au trafic multidiffusion. Une source reçoit un paquet multidiffusion d'un hôte source par un port d'accès, détermine une adresse groupe dans le paquet multidiffusion, et compose et envoie un message "expéditeur présent" à d'autres commutateurs par ses ports réseau. Les commutateurs récepteurs déterminent si un hôte local souhaite faire partie du groupe. Si tel est le cas, ils renvoient un message de relevé d'implantation au commutateur source sur une voie prédéterminée entre le commutateur récepteur et le commutateur source. Il se peut qu'un message de relevé d'implantation aboutisse au niveau d'un commutateur de la voie possédant déjà une liaison pour cette paire groupe/source, et vienne s'y ajouter sous forme de port sortie supplémentaire. De la sorte, un procédé "sortie signal, reconnexion" permet d'établir une voie de connexion entre l'expéditeur et de multiples récepteurs. En outre, le trafic multidiffusion peut être envoyé via une interface commutateur/routeur dans n'importe quel sens, ce qui permet de gérer le trafic multidiffusion entre des réseaux routeurs et des réseaux commutés.

Abstract: In a telecommunications network, broken connections can be detected and located through a next hop loopback technique. The next hop loopback technique involves the generation, transmission, and analysis of specialized data packets which attempt to traverse a telecommunications connection, node by node. The failure of a data packet to properly traverse a link can then be used to determine whether a connection is broken, to notify the network management system as to the location of the broken connection, and whether appropriate action is warranted so that the network operator can re-route data around that portion of the network. In addition, the next hop loopback technique can be triggered on an "as needed" basis by the end user, rather than on a periodic basis, thereby conserving network time and resources.

Abstract: A method of laser processing of materials. The combination of ultrafast laser pulses and high-repetition rate (>1MHz) bursts (or continuous operation) defines a new regime for material processing. The high rate controls thermal processes evolving between each ultrafast laser pulse that 'prepares' the sample surface or bulk for optimal interaction with subsequent ultrafast laser pulses.      The addition of this laser-controlled thermal component overcomes several current limitations of ultrafast laser processing at lower repetition rates (< 1MHz), providing means to fully harness the many attributes by ultrafast lasers for material processing applications.
