Title: Procede de transmission, de decodage ou d'enregistrement compatibles de signaux video balayes progessivement a format entrelace
Inventor: HUETTER INGO
IPC: H04N7/24
Filed: 1992-04-16
Abstract: Transmission compatible de signaux vidéo progressifs en format 16:9. WO91/04637 décrit un système de télévision format "boîte aux lettres" qui permet de transmettre 432 lignes actives progressivement balayées de manière compatible avec le format entrelacé au moyen d'un signal auxiliaire. Ce système ne permet toutefois pas de transmettre des bords horizontaux idéaux de réception progressive, même si l'on fait abstraction des pertes entraînées par un transcodage vertical, ce qui peut affecter la qualité de reproduction de l'image. Afin de générer le signal auxiliaire, la ligne "progressive" située entre des lignes entrelacées adjacentes est prédite à partir de ces lignes et la différence entre cette ligne prédite et la ligne "progressive" réelle est transmise de manière codée dans la bande "boîte aux lettres". Les filtres usuels permettent de reconstruire de manière irréprochable les lignes (P2, P4) non transmises à cause du sous-balayage vertical, mais non les lignes (I1, I3, I5) transmises de manière compatible. Une transmission idéale pour la reproduction progressive peut toutefois être obtenue par des filtres de demi-bande spécialement agencé dans le codeur et par un filtrage inverse dans le décodeur. Alternativement, la qualité de reproduction de l'image peut être améliorée, dans le cas où un filtrage passe-bas usuel est effectué dans le codeur avant le sous-balayage entrelacé, par une reproduction approximative du filtrage passe-bas du côté de l'émission dans le décodeur et par un signal de correction ainsi obtenu. Par formation itérative de ce signal de correction, les signaux vidéo reproduits peuvent être davantage rapprochés des signaux originaux émis. L'invention est applicable à des codeurs et à des décodeurs en format 16:9.

Abstract: On décrit un affichage à guide d'ondes pouvant être commandé, comprenant une gaine (3), une supergaine (1 et 6) et/ou un c÷ur (4) utilisant des cristaux liquides. Un champ électrique appliqué à travers la fibre aligne la couche de cristaux liquides. Des changements produits dans l'indice de réfraction de la couche de cristaux liquides commutent la lumière hors de la fibre. Selon un mode de réalisation, la lumière est couplée dans une supergaine (6) placée le long du c÷ur, et est réfléchie hors de la fibre au niveau d'un puits réflecteur (35) découpé dans la fibre. Des alignements parallèles de fibres sont utilisés pour recouvrir un substrat et produire de grands écrans. Une supergaine (6) à rétrécissement permet d'améliorer le rapport de contraste des écrans à l'aide de prises de fibres. Une gaine mince (3) et une gaine sombre (2) étroitement espacées permettent également d'améliorer le rapport de contraste de l'écran. Des techniques de couleur basées sur une fibre à trois c÷urs qui utilise une supergaine unique (1) sont également évoquées, ainsi qu'un procédé d'éclairage qui fractionne la lumière blanche en composantes de couleur (73) à l'aide de filtres diélectriques (103) afin d'utiliser la lumière blanche (102) de manière efficace. On décrit également un système de réaction électronique (96), lequel permet d'obtenir une uniformité de couleurs et de luminosité sur l'écran dans des conditions de température et ambiantes changeantes.

Abstract: Un matériau composite à base de polyuréthane non-cellulaire comprend des particules de caoutchouc déshydraté coulées dans une matrice de polyuréthane non-cellulaire. On combine ces particules de caoutchouc, qui proviennent de pneumatiques ou d'autres sources, avec un déshydratant qui en retire l'humidité. Les particules de caoutchouc désséché et le déshydratant sont mélangés avec un polyol et un isocyanate et forment un mélange précurseur que l'on cuit afin d'obtenir un matériau composite à base de polyuréthane non-cellulaire. On peut utiliser ce matériau composite résultant caoutchouc-polyuréthane pour des pneumatiques, des semelles de chaussures, des revêtements de surfaces et autres applications exigeant un matériau à structure solide et résistant à l'usure. On peut pré-mélanger les particules de caoutchouc désséché avec le polyol et/ou les ajouter à l'ensemble constitué par le polyol et l'isocyanate pendant le moulage du matériau composite.

Abstract: A system for detecting one or more vehicles, such as a train, on a rail track, comprising at least one optical conductor extending near and parallel to the rail track with a light source and light detector coupled thereto. One or more sensors are coupled to the rail track and include the light conductor, which sensors affect the light attenuation in the light conductor locally upon the presence of the vehicle. The sensor includes a free elongated element, which is connected to the mass of the sensor housing via an elastic hinge connection. One end of the element lies against the light conductor running through the sensor housing, which one end subjects the conductor to a microbending in dependence on displacement of the rail. The elongated element is a pin which runs through a drilled block which is integral with the elastic hinge connection, and at its other end is provided with an outstanding pick-up arm of which the end rests on a contact surface of the fixed substructure of the rail such that the sensor is adapted to detect a displacement or sag of the rail. Said arm end may also be free or the pickup arm may be eliminated such that the sensor is adapted to detect vibrations of the rail. For the purpose of measuring modal noise, the system may comprise an additional optical conductor disposed in close contact with the rail. Said conductor may be suspended in a tube provided with perforated partitions, the optical conductor having vibratory masses attached to it.
