Abstract: A sound reducing system (10) comprises a housing (20), acoustic baffle (60),  and acoustic netting (70). The acoustic baffle is covered with a waterproof protective casing (140) which protects the acoustic baffle from dirt and moisture without interfering with its acoustic properties, and allows it to be cleaned with fluids. The housing (20) comprises an inner pan (30) and an out er pan (40) which are pivotally coupled. The acoustic baffle (60) and the acoustic netting (70) are disposed within the housing (20), but can be remov ed for cleaning when the housing is opened. When the acoustic baffle and acoust ic netting members are placed back within the housing, they are protected from damage.

Title: A method and system for theme-based word sense ambiguity reduction
Inventor: CHALABI ACHRAF
IPC: G06F17/27
Filed: 2002-06-14
Abstract: Word sense ambiguity, for "thematic" words in a sentence, is achieved based on thematic prediction. The senses of "thematic" words are disambiguated in a sentence by determining and weighting possible themes for that sentence. Possible themes are determined for that sentence based on thematic information associated with the different senses of each word in the sentence. A highly deterministic thematic-based word sense disambiguation method is used to preprocess the sentence prior to further syntactic and semantic analysis, thereby enhancing accuracy and decreasing the demand for computational resources (memory and CPU) by reducing input ambiguities.

Filed: 2000-12-22
Abstract: An improved dental adhesive device to hold prosthetic devices in the human mouth is made as a laminate of webs which are bonded together by deforming a  film of thermoplastic ethylene oxide polymer and having an external adhesive  coating on the laminate. The dental adhesive is produced by continuously applying thermoplastic ethylene oxide polymer between moving webs of cellulo se acetate fibers, applying additional thermoplastic ethylene oxide polymer to the external surface of the webs, and then passing said webs in superimposed  relationship between a pair of dry heated calender rolls for thermoplastical ly bonding said webs into a unitary structure. A dry water-activated adhesive material, such as sodium alginate, may be employed with the thermoplastic ethylene oxide polymer by being dissolved or dispersed in the polymer. Synthetic fibers are applied to the webs so as to extend transversely throug h the webs.

Abstract: De manière générale, la présente invention concerne des systèmes et des procédés permettant d'obtenir des informations concernant des chromophores présents dans des milieux physiologiques. Plus particulièrement, l'invention concerne des systèmes et des procédés non invasifs destinés à déterminer des valeurs absolues se rapportant à des hémoglobines oxygénées et/ou désoxygénées ainsi que leurs rapports dans un milieu physiologique. Dans un mode de réalisation préféré, ce système est généralement équipé d'une sonde portable comprenant un module source servant à produire un rayonnement électromagnétique dans un milieu, un module de détection permettant de détecter ce rayonnement à partir d'une zone cible dans ce milieu, ainsi qu'un module de traitement déterminant les valeurs absolues des concentrations des chromophores ainsi que leurs rapports sur la base des paramètres d'entrée et de sortie du module source et du module de détection. Dans un mode de réalisation, l'invention permet d'obtenir une solution pour les paramètres inconnus des chromophores contenus dans un milieu grâce à l'utilisation d'un nouvel algorithme de traitement. Dans un autre mode de réalisation, l'invention concerne une unité portable destinée à effectuer des mesures nécessaires, cette unité étant dotée d'un élément mobile comportant une ou plusieurs sources de rayonnement et un ou plusieurs détecteurs de rayonnement ainsi qu'un actionneur conçu pour amener ledit élément à se déplacer sur des trajets curvilignes prédéterminés. On mesure les propriétés de ces chromophores pour des voxels individuels définis sur chaque trajet de mouvement et/ou pour des voxels transversaux définis au niveau des intersections des voxels sur les différents trajets de mouvement. Dans un mode de réalisation préféré, on utilise alors ces valeurs mesurées pour produire des images bi- ou tridimensionnelles de la répartition des chromophores ou de leurs propriétés. Dans d'autres modes de réalisation, l'invention fait intervenir différents modèles destinés à une répartition optimale des sources et des détecteurs pour la sonde optique, ainsi qu'une opération d'auto-étalonnage de la sonde exécutée pratiquement en temps réel.
