Patent CA-2320177-A1 (CA)
Inventor: GOERTZEN KENBE D
IPC: G06T9/00
Filed: 1999-02-11
Abstract: An interlaced image processing module receives interlaced first and second fields (355a) and produces a reference field and error field (360a). The reference field corresponds to the still image content, whereas the error field corresponds to the motion content between fields. Motion between fields is thus represented in the error field (E), without redundant representation of the still image content provided by the first field. Where there is little motion between fields, the error terms are small so the predictor (315a) preserves the coding efficiency provided by any auto-correlation in the image.  The interlaced image processing method does not rely on pixel group classification, thus avoiding classification errors and the loss of coding efficiency from still image content in motion classified blocks. Problems of relative motion between fields and local artifacts are avoided. Another embodiment transforms the interlaced fields into frame data having high frequency and low frequency fields.

Title: Method and apparatus for refueling an electrochemical engine
Inventor: MCMANIS JAMES V
IPC: B60K15/03
Filed: 2000-10-11
Abstract: A method and apparatus for refueling a vehicle powered by an electrochemical engine comprises a fuel fill pocket accessible to the exterior of the vehicle and having an interior end with an opening to a hydrogen refueling line. The hydrogen refueling line extends between the fuel fill pocket and a storage tank in the engine. A fuel fill door conceals the fuel fill pocket when closed and operates to open for access to the fuel fill pocket. A nozzle is operably connected to a refueling station and is slideably receivable within the fuel fill pocket. The nozzle has a hydrogen input line. The refueling apparatus has a flow communication means to ensure the hydrogen input line is in flow communication with the hydrogen refueling line for delivering hydrogen. Mating communication ports in the nozzle and the fuel fill pocket operate to send and receive electronic signals therebetween and to a controller for controlling the operation of refueling. The controller ensures that the nozzle is properly inserted before initiating refueling and verifies that line pressures are below a minimum set level before the nozzle may be removed from the fuel fill pocket.

Filed: 1999-07-14
Abstract: A method and system for conducting rapid control traffic in a time division multiple access (TDMA) communication system comprises a base station communicating with a plurality of user stations in assigned time slots of a time frame (601). For bearer traffic, time slots are assigned to particular user stations for an extended duration. In unassigned time slots, the base station transmits a general polling message indicating availability of the time slot. A user station desiring to hand off communication from one base station to another uses multiple available time slots at the target base station for exchanging control traffic messages with the target base station.  The next available time slot is indicated by a slot pointer in the header of each general polling message to facilitate rapid exchange of control traffic messages. During handover, the user station may establish a new link with the target base station before relinquishing the existing communication link with the old base station.

Abstract: L'invention concerne un réseau de transmission (110) comportant un mécanisme d'arbitrage qui permet de fournir des garanties de qualité de service pour les données à durée de vie critique partageant un réseau local avec des données à durée de vie non critique. Des adaptateurs (1000) de dispositifs, placés au niveau des points d'accès, limitent le débit d'admission et commandent la synchronisation des paquets entrant dans le réseau. Un pivot X (4) assure le transport transparent et simultané des signaux transmis par les adaptateurs. Les collisions sont évitées pour le trafic à durée de vie critique, ce qui garantit la délivrance en temps voulu desdits signaux. Une référence temporelle commune, définissant une trame à plusieurs phases, est établie pour les adaptateurs et pour le pivot X. Chaque adaptateur est autorisé à transmettre les paquets de données directement à un ou plusieurs adaptateurs destinataires, sans collision, durant une phase où il est en mode interconnexion. Il peut aussi diffuser des transmissions non planifiées au moyen d'un protocole de réseau classique, tel que CSMA/CD, quand il n'est pas en mode interconnexion. La planification des phases peut être modifiée dynamiquement par un protocole de signalisation basé sur les transmissions non planifiées au moyen du protocole de réseau classique quand le pivot X est configuré de cette manière.
