Abstract: L'invention concerne un procédé de détection du virus de Norwalk (VN) dans un échantillon biologique consistant à: obtenir un échantillon biologique supposé contenir un VN; mettre en contact l'échantillon biologique avec au moins un antigène de groupe sanguin humain permettant la formation d'un complexe de VN avec l'antigène; et détecter ledit complexe. Ce dernier peut être détecté par la mise en contact du complexe VN-antigène avec un anticorps VN se liant à un épitope du VN et par la détection de l'anticorps VN. L'invention concerne également un procédé d'identification de composés, et lesdits composés, susceptibles d'inhiber la liaison entre le virus de Norwalk (VN) et un antigène de groupe sanguin. Le procédé consiste à mettre en contact la cible VN avec un composé, à mettre ensuite en contact le VN avec un composé standard qui peut être lié à un site de liaison déterminant du VN; et déterminer si la liaison du composé standard diminue en présence du composé d'essai, la diminution de la liaison indiquant que le composé d'essai inhibe l'activité de liaison du VN avec le composé standard. Dans des modes de réalisation préférés, le composé standard est un antigène de groupe sanguin.

Abstract: La présente invention concerne des mélanges de polypropylène syndiotactique qui présentent un ensemble unique de propriétés mécaniques et peuvent être préparés par mélange de polypropylène syndiotactique avec un polyéthylène à très faible densité et éventuellement un copolymère statistique de polypropylène isotactique. Les mélanges de polypropylène syndiotactique selon cette invention s'avèrent présenter une résistance aux chocs améliorée, un trouble réduit, un pouvoir de transmission lumineuse amélioré et un module d'élasticité en flexion réduit. L'addition d'environ 10 à environ 50 % en poids d'un plastomère de polyéthylène à très faible densité à un polypropylène syndiotactique permet d'améliorer de manière importante la résistance mécanique, notamment à basses températures, tout en conservant une transparence optique satisfaisante. Le procédé mis en oeuvre à cette fin consiste à utiliser un matériau de polypropylène syndiotactique (sPP) qui présente une transparence optique satisfaisante, puis à disperser le plastomère de polyéthylène à très faible densité uniformément dans la matrice de sPP afin qu'il agisse comme un agent modificateur de la résistance aux chocs. L'addition d'environ 10 à environ 50 % en poids d'un copolymère statistique de polypropylène isotactique à la phase de la matrice de sPP permet d'obtenir des propriétés mécaniques comparables ou meilleures, tout en réduisant de manière importante les durées de cycle de moulage par injection. Les mélanges de polypropylène syndiotactique selon cette invention peuvent être traités ultérieurement selon des pratiques acceptées, afin de produire des films coulés, des films soufflés, des films co-extrudés, des feuilles minces stratifiées, des pièces moulées par injection, des conteneurs moulés par soufflage et d'autres articles, en mettant en oeuvre des techniques de base connues de fabrication de matière plastique.

Title: Speaker recognition in a multi-speaker environment and comparison of several voice prints to many
Inventor: LEYVA MARCEL
IPC: H04M3/487
Filed: 2004-05-17
Abstract: One-to-many comparisons of callers' voice prints with known voice prints to identify any matches between them. When a customer communicates with a particular entity, such as a customer service center, the system makes a recording of the real-time call including both the customer's and agent's voices. The system segments the recording to extract at least a portion of the customer's voice to create a customer voice print, and it formats the segmented voice print for network transmission to a server. The server compares the customer's voice print with multiple known voice prints to determine any matches, meaning that the customer's voice print and one of the known voice prints are likely from the same person. The identification of any matches can be used for a variety of purposes, such as determining whether to authorize a transaction requested by the customer.
