Filed: 1995-03-02
Abstract: Dans cette invention, une interface homme/machine utilise des parties de document comme éléments structuraux de base de documents. Au moment où une de ces parties de document est ouverte, il s'établit un lien entre un éditeur ou programme d'édition et la partie en question selon un mode qui utilise de la façon la plus efficace les programmes disponibles dans l'ordinateur. Ce système de création de liens détermine d'abord si l'éditeur préféré pour la partie de document en question est disponible dans l'ordinateur. Si oui, il s'établit un lien entre cet éditeur et la partie de document en question et l'éditeur est lancé, s'il ne tourne pas déjà. Si l'éditeur préféré n'est pas disponible, le système tente de localiser le programme de gestion le plus approprié pour la partie de document en question, sur la base de diverses caractéristiques du contenu de ladite partie, telle que sa catégorie et son type. Si un programme d'édition approprié ou tout autre programme de gestion est disponible dans l'ordinateur, il s'établit un lien entre lui et ladite partie et ledit programme est lancé. Si nécessaire, ladite partie est convertie d'un type en un autre type pour lequel un éditeur est disponible. Si aucun éditeur approprié pour la partie de document en question ne peut être localisé dans les programmes disponibles de l'ordinateur, on crée un lien entre un programme de gestion de dernier recours et la partie de document en question, ledit programme de gestion lui servant alors d'éditeur. Un programme de gestion de ce type constitue un outil générique qui permet de présenter à l'utilisateur la partie de document en question, sans offrir toutes les fonctions qui sont normalement associées à un éditeur pour manipuler le type particulier de contenu de cette partie de document.

Patent CA-2200096-A1 (CA)
Title: Apparatus for reducing transmission capacity
Inventor: WOLF GUENTER
IPC: H04Q11/04
Filed: 1997-03-14
Abstract: When signals are transmitted via an integrated services digital network (NET), the transmission capacity of the individual channels is predetermined.  Two independent integrated services digital networks (NET) can be interconnected, for example via a radio link. However the radio link only has a limited number of channels available, and their transmission capacity is not predetermined.  Before the signals of the first integrated services digital network (NET1) are converted into radio signals, the signals are routed to an apparatus (EIN) where they are compressed and divided. The apparatus (EIN) comprises a demultiplexer (DMUX) for demultiplexing the signals to the individual bearer and signalling channels, a switching unit (S) for separately routing signals to be compressed, e.g. voice signals, and signals not to be compressed, e.g. data signals, an encoding unit (K) in which the signals to be compressed are encoded, a multiplexer (MUX) for joining the encoded, not to be compressed, signalling and packet-switched data signals, and a control unit (µP) for controlling the switching unit (S) as a function of the contents of the signalling signals, and to separately route the signals in the signalling channels onward to transmission channels with different transmission capacities.
