Patent CA-2308460-A1 (CA)
Title: Image coding apparatus, image coding method, image decoding apparatus and image decoding method
Inventor: ISU YOSHIMI
IPC: H04N19/00
Filed: 1998-10-23
Abstract: A coded bit stream 30 generated on a coding side consists of a VO header 30a, a VOL header 30b, a GOV header 30c, a VOP header 30d and VOP data 30e, and the VOL header 30b multiplexes an object intra-coded indicator signal 7' indicating whether all the VOP data 30e contained in a VOL or GOV are intra coded or not. This enables a decoding side to recognize whether all the VOP data 30e contained in the VOL or GOV in the coded bit stream 30 are intra coded or not by only analyzing the object intra-coded indicator signal 7'. This can facilitate such processings as frame skip control or random access of the VOPs.

Patent CA-2313564-A1 (CA)
Inventor: FRIES KARL
IPC: F16B2/16
Filed: 2000-07-07
Abstract: The apparatus comprises a chuck member to be mounted within the operating area of the machine tool and a work piece carrier that can be put onto the chuck member and clamped thereto. First positioning members provided on the chuck member and second positioning members provided on the work piece carrier cooperate to define the position of the work piece carrier along three coordinate axes each running perpendicular to each other as well as with regard to the angular orientation. A clamping mechanism fixes the work piece carrier member to the chuck member in the afore mentioned defined position. In order to ensure an increased resistance against tilting momenta and torque occurring during the machining of a work piece, the first positioning members are constituted by conical centering pins and the second positioning members are constituted by recesses in the shape of a two-stage groove having two shoulders. The edges of the shoulders protruding towards the interior of said groove have a mutual distance that is somewhat less than the width of the conical centering pins, measured between those locations that touch the edges of the shoulders once the work piece carrier is clamped to chuck member.

Abstract: L'invention se rapporte à un couvercle qui est destiné à évacuer les gaz d'une batterie de piles à film métallique mince et qui possède des orifices situés au centre de l'une des extrémités des piles. Les orifices de ventilation comprennent des puits cylindriques (72) qui rentrent dans la partie supérieure des cavités pour piles formées dans le boîtier de la batterie, et qui les remplissent partiellement. La taille des cavités est choisie de manière à ce qu'elles retiennent les piles, lesdites cavités étant configurées pour assurer la connexion électrique en série. Les puits comprennent des tuyaux (71) qui s'étendent vers l'extérieur depuis le fond des puits et assurent la communication avec les orifices faits dans la base des puits. Les orifices dans les tuyaux sont recouverts de capuchons de soupapes souples (77), les puits étant recouverts avec des opercules (78). La disposition centrale des puits enfoncés permet aux gaz provenant des piles de s'échapper à travers les orifices mais empêche l'électrolyte de déborder du boîtier. La base du boîtier de la batterie, qui n'est pas munie d'orifices de ventilation, est interchangeable avec le couvercle, ce qui permet d'orienter le boîtier de la batterie avec les bornes vers le haut ou le bas du corps.

Inventor: SAXENA NEERAJ
IPC: C21B13/10
Filed: 2000-09-18
Abstract: An improved rotary hearth furnace having a cylindrical enclosure containing a radially moving belt for transporting pellets containing metal oxide and carbon is disclosed. One or more oxy-fuel burners preferably having a flat flame shape are positioned so as to provide a mixture of fuel and oxidant to the pellets countercurrent to the direction of the pellets. The oxy-fuel burners are operated so as to provide a pre-determined quantity of oxygen in addition to that necessary for combustion so that the additional oxygen oxidizes the carbon monoxide and hydrogen present in the hot combustion gases. Oxygen injectors may also be used to introduce additional oxygen into the furnace. The additional oxygen is strategically injected into the furnace based on thermodynamic modeling of the furnace so that a substantial majority of the fuel is introduced in a reducing zone so that the reducing zone has a fuel-rich atmosphere while the oxidant is primarily introduced in the heating zone so that the heating zone has a fuel-lean atmosphere.

Abstract: The present invention provides a method and Mobile Switching Center (MSC) for automatically re-establishing a call in a communication system. A call is established on a call path in a communication system between a mobile unit and a network element. A processor, such as a Mobile Switching Center (MSC), determines that the mobile unit has disconnected from the call. The processor automatically re-establishes the call on the call path if it was determined that the mobile unit disconnected from the call. The re-establishment of the call preferably occurs on the call path between the MSC and the network element, and occurs without input from the mobile unit.

Title: Driving force control system for four-wheel drive vehicles
Inventor: NIHANDA NORIHISA
IPC: B60K17/35
Filed: 2001-03-05
Abstract: There is disclosed a driving force control system for a four-wheel drive vehicle, which is capable of properly controlling the execution and cancellation of a lock mode in which the engagement forces of clutches for distributing a driving force to auxiliary drive wheels are made maximum, thereby reducing frequency and duration of the lock mode.  Further, there is disclosed a driving force control system for a four-wheel drive vehicle, which is capable of properly controlling the engagement forces of clutches for distributing a driving force of the main drive wheels to auxiliary drive wheels, thereby causing the clutches to efficiently operate without waste of power. When the vehicle is determined to be in a predetermined low vehicle speed condition, and at the same time, the shift lever of the transmission is detected to be in any of predetermined low-speed shift positions, execution of a lock mode is permitted in which the clutch engagement forces are controlled to lockable ones which can lock the main and auxiliary drive wheels to each other. When the driving force of the main drive wheels is lower than a predetermined value, the clutch engagement forces for the lock mode are limited to smaller ones than the lockable ones.

Title: Procede et appareil pour economiser l'energie dans un terminal mobile avec des connexions etablies
Inventor: LARSSON PETER
IPC: H04L12/56
Filed: 1999-07-27
Abstract: Selon cette invention, on réduit la consommation d'énergie d'un terminal mobile au moyen d'un système dans lequel une station de base indique une période à la fin de laquelle un terminal mobile qui "hiberne" en mode d'économie d'énergie doit se mettre à l'écoute des messages diffusés par la station de base. Si aucun message ne lui parvient, le terminal mobile continue à hiberner et économise la batterie en ne communiquant pas avec la station de base. La station de base tout comme le terminal mobile peuvent lancer une procédure pour faire passer le terminal mobile du mode "éveillé" au mode d'hibernation. Dans un autre mode de réalisation de cette invention, utilisé avec les systèmes qui nécessitent des tests fréquents de connectivité, un agent à l'intérieur de la station de base répond à la place du terminal mobile aux interrogations relatives aux tests de connectivité. Le terminal mobile peut communiquer périodiquement avec la station de base pour mettre à jour les informations utilisées par l'agent afin de répondre aux interrogations relatives aux tests de connectivité.
