Patent CA-2252281-A1 (CA)
Inventor: ARDITO JOHN D
IPC: H04Q9/00
Filed: 1998-10-30
Abstract: A level indicating apparatus for use with a magnetically-actuated remote fluid level sensor prevents misalignment of its magnetic component. The apparatus has a shaft that moves with changing fluid level in a fluid container being monitored, and the shaft is attached to a magnet housing in which is housed a permanent magnet. Themagnet is annularly-shaped and the housing has a curved outer surface that encircles the magnet and physically obstructs it from any radial motion relative to a longitudinal axis of the shaft. A lip on the top of the housing inhibits axial motion of the magnet, and a mounting hole passing through the housing allows attachment to the shaft. The housing may be made of a plastic material that has a degree of elasticity sufficient to allow the magnet to be manually forced past the lip, and sufficient to allow a crimp in the shaft to be forced through the mounting hole, thus allowing the components of the level indicator to be "snapped" together.

Patent CA-2266007-A1 (CA)
Inventor: DUMORTIER PHILIP VINCENT
IPC: H04L12/933
Filed: 1999-04-01
Abstract: The present invention relates to a method and related device to be used to establish a traffic based shortcut when running the Internet Protocol (IP) over a connection oriented network. Such a network may exists of a number of switch-routers and/or one or more IP-routers and/or one or more switches. The shortcutting is performed by the co-operation of the present IP-routers and/or IP-router-parts. The described configuration manages the forwarding of IP  packet flows along a shortcut path. For each shortcut path set-up, a separate virtual channel connection is used. Only a restricted number of virtual channels is available for shortcut paths to be set up. To use the available virtual channels more efficiently, an existing shortcut path can be used to forward one or more IP packet flows simultaneously with, or subsequently to the first shortcutted flow. Also by relating the time-out period of a shortcut path to the local network load the efficiency can be increased.

Title: Procede et dispositif de modulation bidirectionnelle de signaux modules en mode numerique
Inventor: BOTTOMLEY GREGORY E
IPC: H04B7/26
Filed: 1997-12-03
Abstract: La présente invention concerne un procédé et un dispositif de démodulation de symboles numériques transmis via un canal de communication sujet à évanouissements. Le procédé consiste à recevoir (201) séquentiellement une pluralité de premiers symboles numériques (11) prédéfinis, une pluralité de symboles numériques (12) inconnus, et une pluralité de seconds symboles numériques (13) prédéfinis. Le procédé consiste ensuite à stocker les pluralités de symboles numériques (104, 201), et à déterminer (108) un premier et un second ensemble de symboles de références, à partir, respectivement, des pluralités stockées de premiers et de seconds symboles numériques prédéfinis. Un premier bloc constitué d'un nombre prédéfini de symboles numériques inconnus, stockés d'après le premier ensemble de signaux de référence, subit une démodulation aval (154, 203), et ce, en commençant par les symboles inconnus reçus le plus près des premiers symboles numériques prédéfinis. Un second bloc constitué d'un nombre prédéfini de symboles numériques inconnus, stockés d'après le second ensemble de signaux de référence, subit une démodulation amont (155, 203), et ce, en commençant par les symboles inconnus reçus le plus près des seconds symboles numériques prédéfinis. Le procédé consiste alors à évaluer des coefficients de qualité ou "FOM" (56, 57) représentatifs des qualités de démodulation des symboles numériques à démodulation aval et amont, et à les comparer (153, 204) entre eux. Le procédé consiste enfin, d'abord à désigner comme données démodulées, bonnes pour la sortie, l'un ou l'autre des symboles numériques à démodulation aval ou amont, et ce, en s'appuyant sur la comparaison des indices de qualité, et ensuite à sélectionner deux autres blocs et à leur appliquer le traitement jusqu'à épuisement de tous les symboles. Le coefficient de qualité prend en considération des paramètres tels que la puissance du signal.

Title: Switchless call processing
Inventor: CAVE ELLIS K
IPC: H04M3/493
Filed: 1998-04-27
Abstract: A switchless Automatic Call Distribution ("ACD") system distributing incoming calls to call agents networked via a low-cost data network such as an ethernet (220). Standard POTS calls are received from the Public Switched Telephone Network ("PSTN") (102), whereupon a POTS/packet gateway (100) digitizes the signal (103) (if necessary) and compresses it, advantageously from .mu.-law format (64 Kbps) down to approximately 5-6 Kbps. The POTS/packet gateway then converts the signal into a packetized format (107). Responsive to a call distribution algorithm identifying the next available agent by IP address, the caller's packetized voice signals are distributed to the agent over the ethernet. At the same time, Web-enabled database tools (120) generate "documents", advantageously in html, containing database information regarding the caller. These documents are then distributed to the agent over the ethernet. The agent may then converse with the caller using a headset connected to a standard desktop computer running CODEC software to transmit and receive packetized voice signals. At the same time, the computer runs browser software to allow the agent to receive html documents and send back updated information while talking to the caller.
