Title: Detecteur de gaz opto-thermique micro-usine
Inventor: WOOD R ANDREW
IPC: G01N21/17
Filed: 1998-06-26
Abstract: L'invention concerne un détecteur opto-thermique intégré, micro-usiné, comprenant une source de lumière à variation d'intensité ou d'impulsions rapide, un filtre interférentiel, un moyen de masquage perforé ou de blocage réfléchissant de la lumière provenant de détecteurs thermiques, ou fonctionnant en mode différentiel, une cavité de gaz dans laquelle le gaz détecté peut s'écouler par un canal ou un filtre, et des éléments de détection thermique permettant de détecter le chauffage du gaz provoqué par l'absorption de lumière, à une longueur d'onde particulière, par le gaz spécifique à détecter. Une autre version du détecteur comporte deux cavités de gaz. L'une des cavités contient le gaz à détecter, l'autre est étanche au milieu ambiant et ne contient pas de gaz. Les signaux transmis par des détecteurs et provenant des cavités sont soustraits l'un de l'autre, ce qui permet d'éliminer un signal fixe dû au rayonnement incident sur les détecteurs. On peut calculer un rapport du signal provenant des détecteurs pour déterminer la présence de gaz ou de fluide. Le détecteur peut n'avoir qu'une seule cavité avec deux groupes de détecteurs thermiques. Chaque groupe de détecteurs reçoit un rayonnement filtré par un filtre interférentiel qui fait passer le rayonnement d'une longueur d'onde pour un groupe et d'une autre longueur d'onde pour l'autre groupe. Un rapport des signaux résultants provenant des deux groupes de détecteurs thermiques, est respectivement calculé pour déterminer la présence de gaz dans le milieu ambiant proche du détecteur.

Abstract: The specification describes a 'hygienic' handling system in the form of a protective mitt, as opposed to a glove. This mitt-like enclosure is formed of a thin, highly flexible plastic like material, fully sealed on three sides from the apex at the lower end, thereof, to define an upper sealed end. The apex or lower open end, said wrapper being adapted to receive a person's hand, up to and including a portion of one's wrist. The adornment of aforesaid highly flexible wrapper, both protects the user from any contamible ingredient and of equal importance, products, such as food stuff from being contaminated by preparer. The clear, see-through, flexible material allows user to maintain full dexterity of his/her hand extremities and at the same time, maintain a low temperture ratio within said wrapper, therefore, reducing the possibility of user developing a rash that may lead to more serious consequences. The 'face' of said wrapper is treated so as to prohibit, in totality, any tranferance of germs, such as salomonala, and other such bacteria. This 'hygienic' wrapper, in its dual capacity, protects both the user from being contaminated through the handling of products and at the same time protects products from being contaminated by user without such protection.

Abstract: L'invention se rapporte à un système de communication mobile, numérique, conçu de manière à comporter au moins deux canaux de transmission à faible débit pour chaque canal de trafic à interface radio grande vitesse entre une station de base (BTS) et une fonction d'interconnexion (IWF). Les trames radio, telles que les trames EDGE, sont transmises sur un canal de trafic à interface radio. Les trames de transmission, telles que les trames TRAU, sont transmises sur les canaux de transmission. La station de base (BTS) et la fonction d'interconnexion (IWF) assurent la transmission des trames de transmission avec un numérotage des trames et/ou des canaux qui sert à indiquer l'ordre des trames et/ou le canal de transmission sur lequel la trame de transmission a été transmise. Conformément à cette invention, la station de base (BTS) ne restaure pas l'ordre des trames de transmission descendantes en fonction dudit numérotage des trames et/ou des canaux mais elle place les données des trames de transmission et au moins le numérotage de la trame et/ou du canal dans les données utiles de la trame radio descendante à transmettre. La station mobile (MS), par contre, qui extrait les données et le numérotage des trames et/ou canaux des trames de transmission, restaure l'ordre correct des données en fonction de ce numérotage. Cette invention simplifie la structure d'une station de base.

Filed: 2000-03-03
Abstract: Lors de l'installation d'un pêne de porte ainsi que sa plaque de pêne, il es t important de les mettre en parallèle afin de faciliter la fermeture et l'ouverture de la port e. Certains mouvements terrestres dûs au climat, aux glissements ou aux séismes (et autres) peuvent  modifier la position de la plaque par rapport au pêne et empêcher celui-ci de bien fonctionner. Il arrive fréquemment dans nos régions nordiques que le gel et le dégel empêchent nos portes de rester fermées. La présente invention a pour but de modifier la plaque de pêne afin de l'adapter aux différents mouvements de la croûte terrestre. Pour se faire, l'invention utilise un mouvement coulissant (de ha ut en bas) de la plaque, ce qui permet à celle-ci de suivre le déplacement du pêne.  Cette invention possède les mêmes caractéristiques qu'une plaque de pên e régulière à la différence que celle-ci est composée de deux pièces assemblée s et coulissantes.
