Abstract: A method of assisting a sales representative to manage a sales opportunity, and a program storage device and computerized sales automation system for implementing the method. The method includes the steps of: establishing an actual sales cycle for an actual sales opportunity, the actual sales cycle having a start date and an end date;  establishing a degree of focus curve for each of the sales skills of probing, proving, and closing as a function of time within the actual sales cycle, and dividing the sales cycle into probe, prove, and close phases in which the probing, proving and closing degree of focus curves are respectively greater than the other degree of focus curves; comparing actual data relating to the actual sales opportunity with model data relating to a model sales opportunity and determining the nature and extent of any gap between the actual data and the model data; and providing a response to the sales representative to assist the sales representative in modifying activities and strategies for closing any gap or for winning the sale. The response is based, at least in part, on the phase of the sales cycle. The method also includes a novel and more accurate means of determining the "probability" that a sale will be won which entails having the sales representative enter his gut feeling on two issues that affect probability. The system calculates a unique value based on this information. The "priority" associated with a sales opportunity is calculated based on the combination of probability and the point of time in the sales cycle. Using information supplied by the user, the system can also calculate its own probability and priority values to check the sales representative's own gut feel.

The reverse link transmitter stops channel transmission on the reverse link in response to the transmission control signal.
Patent CA-2328822-A1 (CA)
Title: Heat exchanger
Inventor: MACKELVIE WINSTON R
IPC: F24D17/00
Filed: 2000-12-28
Abstract: A fluid-to-fluid heat exchanger for use where two fluid streams may be of indeterminate composition, temperature, and flow rate, and, where the two fluid streams may flow at different rates and at different times. Such conditions are found, for example, in the flow patterns of a building's hotwater, cold feed water for a water heater, and drainwater. As defined for heat recovery from drainwater, the present invention comprises a first, central, straight-through heat exchanger tube for cooling flowing drainwater, a second heat exchanger to heat cold water encircling and spaced from the first, and a non-pressurized reservoir between first and second heat exchangers permanently filled with water in thermal contact with first and second heat exchangers. Submerged in the reservoir water there is at least one insulated convection chamber, of small volume, enclosing first heat exchanger with a convection opening uppermost. Opening allows upward convection and therefore heat transfer when drainwater heats convection chamber water making it lighter. Convection and heat transfer ceases when drainwater cools convection chamber water making it heavier, blanketing drainwater heat exchanger in a small volume of cold water. This one-way heat transfer prevents heat loss from remaining reservoir water to cold drainwater. With convection chambers inverted to have convection opening bottommost, the device serves to make coldwater, for drinking, as cold as possible by transferring unwanted heat to colder drainwater. Used in series, heat recovery and fresh water cooling can both be accomplished. Units for horizontal and vertical installation are disclosed.

Abstract: L'invention porte sur un système éliminant d'un signal cible produit par une source cible les signaux parasites produits par une source de parasites. Un diviseur de faisceau (114) divise le signal cible en une série de signaux cibles de largeur de bande limitée (à largeur de bande limitée en fréquence), et divise le signal parasite en bandes à largeur de bande limitée en fréquence correspondantes. Un filtre adaptatif (500) filtre les signaux parasites à largeur de bande limitée de chacun des signaux cibles de largeur de bande limitée. Un sélecteur de faisceau (112) sélectionne les faisceaux simultanément pour améliorer la précision et sélectionne en particulier un faisceau à direction fixe, et un faisceau à direction tournante. Une barrière de bruit (120) commande le signal principal passé par le filtre adaptatif en s'ouvrant quand le rapport signal/bruit d'ambiance dépasse un seuil prédéterminé, et en se fermant quand ce même rapport n'atteint pas ledit seuil. Lorsque le signal cible consiste en conversations d'ambiance provenant d'une téléconférence le filtre adaptatif (500) supprime l'écho présent dans le signal de référence diffusé à l'extrémité éloignée de la téléconférence.

This is achieved by the provision of support for multimedia and real-time traffic in large bandwidth routing devices known as terabit routers. Each terabit router has a plurality of ingress line interface cards (210, 212, 214, 216), a plurality of egress line interface cards (220, 222, 224, 226) and a cell based cross-bar (202). Each ingress card has a plurality of queues, a different queue for each of the egress cards respectively. The cross-bar (202) is controlled by a cross-bar controller (204) in association with a bandwidth controller (206). In operation, a target rate matrix is maintained over a set period. At the beginning of each period, a matrix of numbers of cells queued to be transmitted is calculated in accordance with the target rate. For each successive cell slot within the period, a configuration is found which matches the cell number matrix by servicing only queues which have non-zero cell counts. At the end of the period, the cell counts are all zero.
