Title: Brg with pbx capabilities
Inventor: WANG SPENCER
IPC: H04L29/02
Filed: 2000-11-15
Abstract: A residential private branch exchange (PBX) allowing IP telephones, analog telephones and computers to connect to an IP communication network. A  broadband residential gateway (BRG) PBX provides residences with multiple phone lines capability and the implementation of complex calling features traditionally associated with complex and expensive business PBX systems. The BRG PBX provides an open architecture interface minimizing problems during installation and operation, minimizes interoperability problems across multi-vendor equipment platforms and may provide customers with an option to bypass the local telephone company's high cost infrastructure. The BRG PBX may also provide a range of services from basic calling with few features to highly sophisticated calling features servicing multiple phone lines to the residence. The BRG PBX may be configured to connect multiple BRG PBX  systems together in a Local Area Network (LAN) or Wide Area Network (WAN) configuration. These network configurations may be implemented to connect neighborhoods or families across multiple geographic regions. In addition to having the capability of connecting to each other, the BRG PBXs may be connected to IP Central Stations forming an IP communication network.

IPC: H04Q3/00
Filed: 1999-05-18
Abstract: A telecommunications service node (10) includes a multi-level architecture comprising an operating system layer (12) interfaced using a compile time linked interface (22) to a service framework layer (14), and a service application layer (16) interfaced using an object oriented, run time linked interface (22) to the service framework layer. Run time linking of the service applications supports the introduction or modification of service applications during nun time execution (74) of the service node. Each service application inherits from the same base class (32), and is defined by certain criteria (18) which need to be met in order to execute the service.      A trader (28) maintains a reference to each available service application.      When a certain service needs to be performed (40), a set of criteria for that certain service arc evaluated (44) by the trader, and a particular one of the service applications within the service layer defined to meet the criteria set is selected (46). The selected service application is then invoked (52) to support the certain service. Following termination (56) of the invoked service application, the service is shut down (60) in a controlled fashion.

Abstract: The present invention relates to a new, particularly economical process for preparing particulate water-soluble cellulose derivatives. The process involves forming a feed composition of swollen and/or dissolved cellulose derivative, and water. The feed composition is contacted with a superheated gas mixture, in a sieve-free high rotational speed gas jet impact mill, and the cellulose derivative of the feed composition is converted into a solid state form of finely particulate particles. The superheated gas mixture, with which the feed composition is contacted, is selected from: (i) a superheated gaseous mixture of steam and an inert gas; and (ii) a superheated gas mixture of steam and air. The superheated gas mixture has a steam content of 40 wt. % to 99 wt. %, based on the total weight of the superheated gas mixture.

IPC: B27B1/00
Filed: 2001-03-08
Abstract: 1.0 PROBLÉMATIQUE   La rentabilité financière et environnementale d'une usine de sciage dépend en bonne partie de la valeur ajoutée à la matière première qui est des billes d e bois. Il est donc important de maximiser le volume de produit transformé pour chaque bille. C'est ce que l'on nomme le rendement matière.  Pour ce faire, les systèmes de sciage actuels lisent la forme de chaque bill e à l'aide d'un scanner, ajustent les outils de coupe et tournent la bille à l'angle qui sera le plus favorable au rendement matière. Certains systèmes orientent aussi la bille afin d'en tirer le maximum. Cette action, est particulièremen t intéressante pour les billes ayant une forte conicité (voir figure 1). Cependant, les imperfections de forme des billes (noeuds, trous, ovalité, etc.) ainsi que des jeux mécaniques limitent la précision de ce positionnement.</S DOAB>

Abstract: L'invention concerne un procédé qui permet de contrôler la distribution de structures sur une surface ou de particules dans l'espace. Selon le procédé, on génère une image optique bidimensionnelle de la distribution, par exemple par une technique vidéo; on convertit l'image en pixels; on détermine la luminosité moyenne de chaque pixel; et on calcule les différences de luminosité entre pixels adjacents pour des lignes prédéterminées de pixels. Ces valeurs différentielles sont enregistrées et/ou affichées sur un support de données de façon que leur corrélation avec la position des pixels soit conservée sur l'image. A partir de là, on calcule à quels endroits apparaissent des inhomogénéités dans la distribution des structures sur la surface ou des particules dans l'espace. Ce procédé peut être utilisé par exemple pour évaluer l'homogénéité de surfaces, détecter les défauts superficiels ou contrôler l'angle d'ouverture et l'homogénéité d'un jet.
