Title: An information retrieval system
Inventor: JIANG JASON
IPC: G06F17/30
Filed: 2001-10-17
Granted: 2015-12-29
Abstract: An information retrieval system, including a natural language parser (3) for parsing documents of a document space (1) to identify key terms of each document based on linguistic structure, and for parsing a search query to determine the search term, a feature extractor (4) for determining an importance score for terms of the document space (1) based on distribution of the terms in the document space (1), an index term generator (5) for generating index terms using the key terms identified by the parser (3) and the extractor (4) and having an importance score above a threshold level, and a query clarifier (16) for selecting from the index terms, on the basis of the search term, index terms for selecting at least one document from the document space (1). A speech recognition engine (12) is used to generate the query, and a bi-gram language module (6) generates grammar rules for the speech recognition engine (12) using the index terms.

Abstract: L'invention concerne la transmission en continu de données en temps réel (vidéo, par exemple) sur des réseaux à commutation par paquets (Internet, par exemple). De façon classique, dans les réseaux à commutation par paquets, pour la visualisation de données vidéo émises en continu, un réservoir de données est construit pour réduire les effets de gigue, causés par des variations dans les temps s'écoulant entre les arrivées de paquets de données. Par conséquent, un retard se produit avant que le matériel vidéo puisse être visualisé, à mesure que le réservoir se remplit. L'invention concerne la fourniture de données vidéo émises en continu sans le retard de démarrage, par émission de ces données d'un émetteur vidéo en continu à un visualiseur vidéo à une vitesse supérieure à celle à laquelle le visualiseur vidéo consomme les données, et par utilisation du surplus de données pour construire un tampon au niveau du visualiseur vidéo. Lorsqu'un tampon dimensionné approprié est construit, la vitesse de transmission des données vers le tampon peut être réduite. Afin de fournir à la bande passante appropriée un matériel de la meilleure qualité, on peut commuter la fourniture de données vidéo sur une source à débit binaire supérieur lorsque le réservoir est rempli. Les fluctuations dans un débit de réseau peuvent être compensées lors de la transmission des données sur une échelle fine par régulation de la vitesse de transmission des données, et sur une échelle grossière par commutation entre des trains de données codés à des débits binaires différents. Les fluctuations dans un débit de réseau sont déterminées par le dénombrement de paquets manquants au niveau du visualiseur vidéo, information qui peut être ensuite réacheminée vers le visualiseur vidéo pour réguler en conséquence le flux de données.

Abstract: A track for a toy vehicle is provided. The inventive track includes at least one end segment, either male or female, and at least one middle segment. The middle segment is pivotably attachable to at least one of the male and female segments. A middle segment can have teeth on both ends, tooth-receiving cavities on both ends, or a set of teeth on one end and a cavity on the other. The teeth of one segment are selectively engageable with the edges of a cavity of an adjacent segment. When teeth engage a cavity, one segment is fixedly angled with respect to the other segment. By repeating this pivotably angled structure between a number of segments, the curvature of the track can be altered to the taste and specifications of the user.

Abstract: La présente invention concerne une combinaison de bandes qui présente une rangée de poches ouvertes au moins sur un côté de la combinaison de bandes, permettant d'accueillir des extrémités de lattes. Cette combinaison de bandes est produite sous forme de combinaison de deux parties de bande (3 et 4), qui sont reliées l'une à l'autre de façon adéquate et reposent l'une sur l'autre de manière sensiblement plane. La première partie de bande (3) est constituée d'une matière rétractable (telle que du coton) et la seconde partie de bande (4) est constituée d'une matière non ou peu rétractable (telle que du Nylon ou du coton prérétréci). Ladite combinaison de bandes est soumise à un processus de retrait. Il se forme alors des poches qui ne sont plus planes, mais qui présentent un fond de poche rétréci sur lequel se trouve une partie de poche bombée. La combinaison de bandes selon cette invention peut être produite très facilement et présente une longueur constante, que les extrémités des lattes soient introduites dans les poches ou non. Elle peut facilement, avec la partie rétrécie, être cousue sur un protège-lattes ou sur un protège-matelas.

Abstract: Une méthode de positionnement d'un manchon dans un fond de trou de puits d'hydrocarbures. Un ensemble de descente avec manchon associé est descendu dans un puits produisant des hydrocarbures jusqu'à ce que le manchon soit dans une position désirée dans un conduit. Le manchon est dilaté jusqu'à ce qu'il entre en prise de façon étanche avec le conduit. La pression est maintenue dans le manchon jusqu'à ce que les joints maintenant la pression séquentiellement ne réussissent plus à dilater les extrémités du manchon. Quand un seuil de pression préréglé est atteint, la pression est relâchée. L'ensemble de descente est ensuite remonté à la surface à travers le manchon dilaté. Un avantage majeur de cette méthode est que le manchon dilaté fournit suffisamment de dégagement interne qu'un manchon supplémentaire de la même taille que l'original pourra, par la suite, être passé à travers le manchon dilaté et positionné plus bas dans le puits.
