Title: Reduced-complexity max-log app decoders and related turbo decoders
Inventor: HUNT ANDREW W
IPC: H03M13/03
Filed: 1999-06-01
Granted: 2007-08-07
Abstract: Methods of reduced-complexity max-log-APP processing are disclosed for use with Turbo and Turbo-like decoders. The invented methods of decoding are derived from max-log-APP processing and significantly lower the processing required for decoding convolutional codes by eliminating a portion of the calculations conventionally associated with max-log-APP processing. The disclosed embodiments provide simplified methods of metric combining based on determining the bits of an MLSE sequence with different alterative approaches. Also disclosed is an early stopping method that uses the reduced-complexity max-log-APP decoder to reduce the average number of decoding operations required by an iterative Turbo decoder.

Title: Continuous centrifugal separator of heavier particulate materials from light particulate materials in a slurry
Inventor: KNELSON BENJAMIN
IPC: B04B1/00
Filed: 1999-07-07
Granted: 2006-07-04
Abstract: A centrifuge bowl for separating heavier particles from lighter particles and water comprises a first conical bowl wall leading to a pair of annular recesses at actually spaced positions. Each recess is generally re-shaped with an upper side wall, a lower side wall and a base. The base contains a plurality of angularly spaced discharge ducts each having a mouth projecting through the base into the interior of the bowl for collecting the heavier particles. A pinch valve is formed as an integral assembly with the mouth and duct and is mounted within a housing carried within the wall of the bowl. The housing, valve and duct can therefore be removed as a separate assembly by pulling from a chamber within the wall of the bowl. A compression fluid supply duct passes through the wall to communicate with the chamber. Each recess includes injection openings in the upper and lower side walls of the recess arranged to inject fluidizing water in a direction generally parallel to the base and across the mouth of each discharge duct. The injection openings are inclined so as to tend to direct the water around the recess.

Title: Distributed interface architecture for programmable industrial control systems
Inventor: CRATER KENNETH C
IPC: G06F9/44
Filed: 1998-05-06
Granted: 2004-02-03
Abstract: An integrated control system comprises one or more controllers each equipped to perform a control function and to gather data (ordinarily from sensors or a video camera) relevant to the control function. Each controller contains computer storage means, such as computer memory, for storing the relevant data and instructions, associated with the data, for causing a remote computer to generate a visual display incorporating the data in a predetermined format; and a communication module for establishing contact and facilitating data interchange with the remote computer. The remote computer, in turn, also includes a communication module compatible with the controller-home module, and which enables the remote computer to download the data, including current video information and/or historical and/or reference video information, and associated instructions from one or more controllers. The remote computer also includes a facility for processing the instructions to create a user interface encoded by the instructions, and which incorporates the data. In this way, controller data is coupled to instructions for displaying that data, and this totality of information is continuously accessible, on a freely selective basis, to the remote computer.
Patent CA-2290137-C (CA)
Inventor: CARON PAUL
IPC: C23C24/10
Filed: 1998-05-27
Granted: 2008-08-12
Abstract: La pièce mécanique à surface antiabrasion est caractérisée en ce qu'elle comprend un corps métallique fritté obtenu par métallurgie des poudres et un revêtement en cermet déposé par la technique au laser. Le revêtement a une certaine épaisseur dont une portion est métallurgiquement liée au corps métallique. Le dépôt par laser permet de fondre en surface la pièce frittée à revêtir sous l'effet du faisceau laser. La surface de la pièce frittée à recouvrir est donc fusionnée sur une épaisseur pouvant aller de 10 .mu.m à 1mm, ce qui permet la fermeture des pores en surface, typique aux pièces frittées et, par conséquent, l'accroissement de sa résistance au choc. De plus, la faible surface couvert e à un instant donné par le laser permet l'auto-trempage de la zone exposée, suite au déplacement du faisceau, par effet de puits de chaleu r du volume métallique environnant. Le revêtement obtenu selon la présente invention présente aussi une très faible porosité à cause de la fusion complète des poudres de la pièce frittée par le laser.

Granted: 2005-10-04
Abstract: This relates to a gas separator (8) of the cascade type, with stratified or non-stratified flow, equipped with automatic level control to perform a process of the gravitational separation of two immiscible fluids of different densities, particularly to separate the gaseous phase from a two-phase mixture (liquid and gas). It is installed at the bottom of an oil well, upstream from a lifting pump (12) in order to minimize the entry of gas into pump (12). The level control system comprises a valve (29), a spring (30) and a packer (26). It is based on the combined effects of the abovementioned components (26, 29, 30), the gas pressure on the region of perforated casing (10) and the thrust exerted on a settling vessel (3) by the liquid on which it floats. The separator according to the invention has a control system for the level of the liquid stored in settling vessel (3) mounted within its separator (8), ensuring flow of the mixture which is ideal for the occurrence of gas separation.

Abstract: Selon cette invention, un système (18) de récupération des vapeurs utilise un oscillateur à quartz (30) pour détecter la présence d'hydrocarbures dans les vapeurs émanant d'un réservoir de carburant (10) pendant le remplissage. L'oscillateur à quartz (30) est recouvert d'une couche faite d'un matériau sensible à la présence d'hydrocarbures. Sous l'effet de toute interaction entre la couche de revêtement et un hydrocarbure, l'oscillateur à quartz (30) subit un déplacement de fréquence d'oscillation par rapport à la fréquence de résonance fondamentale. Le déplacement de fréquence (34) est représentatif de la concentration des hydrocarbures dans les émanations de vapeurs. Un signal de commande (36) basé sur le déplacement de fréquence (34) est généré; il est ensuite utilisé pour réguler la vitesse de fonctionnement de la pompe à vapeur (26).
