Abstract: A master station sends polling signals to each slave station with respect to CBR data to which required constant bandwidth has been allocated. Next, the master station sends polling signals to each slave station with respect to VBR data with its average bandwidth kept constant. Finally the master station sends polling signals to ABR data to which residual bandwidth has been allocated. The bandwidth of a frame is allocated to a plurality of data from higher to lower priority order.          Therefore excellent traffic characteristics can be obtained even when a plurality of data of different traffic characteristics are mixed in the system.

Title: Appareil et procede d'interfacage d'un processeur de donnees et d'un controleur des entrees/sorties avec une memoire centrale
Inventor: OLSON STEPHEN W
IPC: G06F13/28
Filed: 1994-03-24
Granted: 2002-02-19
Abstract: L'invention concerne un procédé et un appareil d'interfaçage d'un processeur central (12) et d'un contrôleur des entrées/sorties (30) avec une mémoire centrale (40). Un processeur central et un tampon d'écriture ES comprennent chacun une paire de registres de données d'entrées mémoire situés dans une paire de circuits intégrés (38a, 38b) d'unité de données de mémoire ainsi que deux paires de registres d'adresses de mémoire, un registre d'anciennes adresses mémoire et un comparateur d'adresses situés dans une unité d'adresses de mémoire (36). Ces registres sont utilisés conjointement avec une unité logique de commande associée pour tamponner les adresses et les données d'écriture E/S et du processeur central envoyées dans la mémoire centrale. Si l'écriture des deux registres d'adresses est en souffrance, la concordance du dernier registre d'adresses chargé avec l'adresse d'écriture en cours est vérifiée au moyen du registre d'adresses précédent et du comparateur. La concordance résulte de la combinaison des précédentes données d'écriture et des données d'écriture en cours de manière à former une écriture en souffrance, au moyen de circuits de fusion d'écriture dans les unités de données mémoire (MDU). Les opérations de lecture ES sont réalisées d'abord par chargement des registres de données de lecture de MDU avec les données de lecture en provenance des emplacements mémoire spécifiés par une adresse alignée à mot quadruple dans le premier registre ES, suivie par une adresse alignée à mot quadruple incrémentée dans le deuxième registre d'adresses E/S. Le transfert commence alors et toutes les adresses de lecture ES sont vérifiées de manière à permettre une comparaison des mots quadruples courante. Si une adresse de lecture ES alignée à mot quadruple n'est pas égale au contenu du précédent registre d'adresses ES, une demande de lecture de mémoire est générée au moyen de l'adresse incrémentée et les registres de données de lecture MDU sont avancés. Le procédé selon l'invention se caractérise par le fait qu'aucune adresse spécifique n'est utilisée et qu'aucune connaissance de la largeur de transfert (octet, mot) n'est requise pour déterminer les types d'opération de la mémoire.

Patent CA-2195899-C (CA)
Inventor: DEZONNO ANTHONY J
IPC: H04N7/173
Filed: 1997-01-24
Granted: 2001-06-05
Abstract: A video switching system 108 automatically establishes video communications between an agent terminal 110 and a video communications device 104. A  telephonic switch, such as an automatic call distributor (ACD) 102, selects which agent terminal 110 receives the video communications and generates reports relating to the video communications. A programmable switch 105 receives an initial request from the video communications device 104 to establish video communications. A computer system detects the initial request and instructs the ACD 102 to select the agent terminal 110 which is to receive the video communications. The ACD 102 selects the agent terminal 110, or an agent associated with the agent terminal 110, using known methods and transmits the selected agent terminal 110 to the computer system 112. The computer system 112 instructs the programmable switch 105 to route the video communications to the selected agent terminal 110. When the ACD 102 receives the instructions to select the agent terminal 110, the ACD 102 begins to collect information relating to the video communications. The computer system 112 detects when the video communications has ended and notifies the ACD 102. In response, the ACD 102 stops collecting information, such as communication time, and makes the agent terminal 110 available.

Title: Arc furnace fume collection system
Inventor: SIERADZKI CHRISTOPHER Z
IPC: F27B3/08
Filed: 1997-06-12
Granted: 2000-08-29
Abstract: The present invention provides a system and method for collecting fumes from an arc furnace of the type typically used in metal foundries. The system provides an electrode hood with extended sides for improved collection of fumes from the vicinity of the electrodes. It also provides a movable spout hood for collection of fumes when metal is tapped. A combination of a tilting manifold and stationary duct are used to maintain a path for collecting fumes throughout the entire range of motion of the furnace. The stationary duct has a group of dampers that open and close as the furnace tilts. Variable position dampers may be provided at the electrode hood and furnace door. In the bag house, there is a dust containment assembly to limit the movement of the collected dust. A variable speed fan may be used with the system. One method of the invention involves determining the pressure differential upstream and downstream of the filter bag, determining the fan speed, and closing a damper downstream of the filter to clean the filter bag when the determined values for the pressure differential and fan speed match previously set values. The entire system may be controlled by a programmable logic element to maximize efficiency. Another method involves the steps of adjusting the electrode hood damper, spout hood damper and door hood damper in response to furnace conditions.

Title: Time-based paging for mobile telephone units
Inventor: HANSON ROBERT J
IPC: H04W68/08
Filed: 1997-10-31
Granted: 2002-04-16
Abstract: An arrangement for paging mobile telephone units (MTU) in a cellular mobile system that conserves paging resources. If the elapsed time since the most recent registration of an MTU is small, then an initial page covering only the cell of the most recent cell location for the target MTU, and the neighboring cells for that cell, is used. Advantageously, since the likelihood that the MTU is still within that cell or its neighbors is high, so that paging resources are conserved by paging in only a small number of cells.

Granted: 2008-02-05
Abstract: An extrusion die comprises a die cavity having a shape corresponding to the cross-sectional shape of the required extrusion, and a preform chamber in communication with the die cavity, the preform chamber being of generally similar shape to the die cavity but of greater cross-sectional area, so that regions of the preform chamber communicate with corresponding regions respectively of the die cavity. Each region of the preform chamber has a bearing length which is so determined in relation to its dimensions and position that, in use, extrusion material passing through each region of the preform chamber is constrained to move at a velocity such that the material passes through all regions of the die cavity at a substantially uniform velocity. The die cavity itself is of uniform, preferably zero, bearing length so that the extrusion process is controlled solely by adjustment of the preform chamber, such adjustment then being readily quantifiable and repeatable.
