IPC: H04L27/06
Filed: 1998-07-06
Abstract: Le dispositif d'accord d'un téléviseur numérique convertit un signal reçu en un avant-dernier signal à fréquence intermédiaire (FI). Les avant-dernières oscillations locales sont transmises en une première et une deuxième mises en phase, la deuxième consistant en une mise en quadrature avec la première, pour hétérodynage avec l'avant-dernier signal FI dans un premier et un second mélangeurs respectivement afin de générer une composante réelle et une composante imaginaire d'un dernier signal FI.

Un premier circuit de conversion analogique-numérique contenant un nombre N de convertisseurs analogiques-numériques numérise la composante réelle du dernier signal FI sur une base de N phases, N valant au moins un. Un deuxième circuit de conversion analogique-numérique, qui contient un nombre N de convertisseurs analogiques-numériques,  numérise la composante imaginaire du dernier signal FI sur une base de N phases. Une porteuse numérique complexe est générée à la fréquence de la porteuse convertie dans la bande du dernier signal FI. Un circuit de synchrodynage répond à la porteuse numérique complexe transmise sous la forme des dernières oscillations locales, et aux échantillons numériques de la composante réelle et de la composante imaginaire du dernier signal FI, afin de récupérer les composantes en phase et en quadrature du signal en bande de base.

Inventor: HENRY JAMES W
IPC: A01C7/08
Filed: 1998-10-28
Abstract: The invention relates to a spreader for use on a delivery tube of a seeding tool.

Patent CA-2255007-A1 (CA)
Inventor: SCHOCK SAM S
IPC: F01B9/02
Filed: 1998-12-04
Abstract: A crankshaft for a reciprocating piston engine has a circular main shaft supported by conventional bearings so as to rotate about the centroidal axis of the main shaft, plus a circular connecting rod journal formed monolithically with or fixedly attached to the main shaft. The connecting rod journal is larger in diameter than the main shaft, and the centroidal axes of the connecting rod journal and the main shaft are separated but parallel, such that the connecting rod journal will rotate eccentrically around the centroidal axis of the main shaft. The connecting rods from the pistons are rotatably mounted to a connecting rod bearing journal which rotatably encircles the connecting rod bearing journal.  When a piston is in its power stroke, the resultant force in the corresponding connecting rod imparts eccentric rotation of the connecting rod journal about the centroidal axis of the main shaft.

Patent CA-2259267-A1 (CA)
Title: Pipeline utilization enhancement including carbon dioxide gas transmission, distribution, and delivery technique
Inventor: ERICKSON STEWART E
IPC: C05D7/00
Filed: 1997-06-27
Abstract: The present invention involves utilization of carbon dioxide, CO2, gas produced from various natural and manmade sources. Where such gas is vented as a waste by-product into the atmosphere, it is a leading gaseous emission contributing to the Earth's atmospheric greenhouse effect and ultimately to devastating global warming. The present invention can include a method of transmission, distribution and utilization of CO2 gas. This aspect of the invention includes the transmission of CO2 gas through idled natural gas pipelines during summer months and delivery of the CO2 gas to field crops to increase crops' yields. This method will increase the seasonal utilization "load factor" of natural gas pipelines during "off-peak" non-heating months, when natural gas is in low demand. Further, the invention can provide a distribution mechanism consisting of a series of trunk lines with gate valves linking to primary manifolds. The primary manifolds may in turn be connected to a series of secondary exhaust pipeline rows. This gas distribution system is compatible with existing farming practices and farming implements. Automated delivery of CO2 through the distribution mechanism's rows of exhaust pipes is easily adapted to remote control by electronic field monitoring devices that economically, precisely, and evenly distribute CO2 gas to field crops. The gas distribution grid, electronic monitoring and automated delivery controls can all be linked in a gas preparation facility designed to optimize the gaseous medium including CO2 concentrations and temperatures incident to crops for photosynthesis.
Patent CA-2259713-A1 (CA)
Inventor: MARUFLU BURC Z
IPC: G09F11/08
Filed: 1999-01-20
Abstract: The present invention is a unique multi-leaf rotating sign mechanism which incorporates a simplified multi-part drive shaft mechanism for rotating the leafs. The drive shaft directly engages a system of pins and flats on the end of each leaf to produce an intermittent rotation of the leafs so as to expose the desired messages placed on the flats of the leafs in a step-wise fashion. The drive shaft also provides a feature to prevent turning of the leafs during the non-rotational portion of the sign's cycle.
Patent CA-2262044-A1 (CA)
Title: Optimizing call-center performance by using predictive data to distribute agents among calls
Inventor: SKARZYNSKI STEPHEN L
IPC: H04M3/523
Filed: 1999-02-15
Abstract: Selection of a call for handling by a call-center agent (106-108) is based on which call's handling by the available agent will tend to optimize call-center performance criteria such as efficiency (e.g., minimize per-call handling time) or derived benefit (e.g., maximize revenue). Each agent has a service profile for each type of call that they handle. A service profile (400-402) comprises present values of a plurality of service metrics, such as proficiency, profitability, customer satisfaction, and agent satisfaction. When an agent becomes available, the present values of the service metrics of the service profile (500-502) of that agent for each type (e.g. skill) of available call handled by the agent are combined (610) into a score according to one of a plurality of formulas which corresponds to that call type, and a call of the type for which the agent has the best (e.g., either highest or just-sufficient) score is assigned (612) to the agent.      Preferably, a call score is also computed (807) for each available call type, based on factors such as the purpose of the call, the call's in-queue wait time, the priority of the call, etc. The call type for which the agent has the best score is selected (812) to be the one for which the call score best matches the agent's corresponding score. When the assigned agent finishes handling the call, his or her performance is evaluated (202-206) based on the service metrics, and the valuations are used (210) to revise the present values of the service metrics of that agent's service profile.      The revision process gives (208) more weight to valuations of more-recently-handled calls to reflect both long-term and short-term agent performance trends and variations.
