Title: Correcteur d'amplitude pour une pluralite de signaux optiques et procede correspondant
Inventor: PEDERSEN CLAUS FRIIS
IPC: H04B10/2537
Filed: 1997-09-25
Abstract: La présente invention concerne un procédé de correction d'amplitude d'une pluralité de signaux optiques de différentes longueurs d'ondes, les signaux optiques étant injectés par une première extrémité d'une fibre optique. Le procédé consiste, avant de les envoyer dans la fibre optique (5), à amplifier les signaux jusqu'à un niveau selon lequel l'un au moins des signaux dépasse une valeur de seuil (TSBS) de stimulation Brillouin stimulée (SBS) caractéristique de la fibre, et ce, defaçon qu'une partie de l'énergie du signal dans la fibre se transfère en un signal de Stokes se propageant dans la fibre (5) dans un sens opposé au signaux optiques considérés. L'invention concerne également un correcteur d'amplitude destiné à une pluralité de signaux optiques de différentes longueurs d'ondes. Ce correcteur comporte une fibre optique (5) caractérisée, d'une part par une extrémité d'entrée (6) par laquelle les signaux sont injectés dans la fibre, et d'autre part par une extrémité de sortie (10) d'où les signaux peuvent être repris après correction. La fibre est affectée d'une valeur de seuil (TSBS) de stimulation Brillouin stimulée (SBS) caractéristique qui correspond, en extrémité de sortie (10) de la fibre, à une valeur d'amplitude maximale définie pour les signaux optiques.

Abstract: La présente invention concerne un dispositif de fermeture hermétique (16) destiné à des ensembles paliers constitués d'un premier palier (3) présentant une première voie interne (5) et d'un second palier (4) présentant une seconde voie interne (8). De telles voies internes (5, 8) sont disposées côte à côte sur un arbre (1) de façon à laisser un intervalle (12) entre elles (5, 8). Par cet intervalle, on introduit de l'huile entre l'arbre considéré (1) et les surfaces des voies internes (5, 8) tournées vers l'arbre (1). L'invention est caractérisée, d'une part en ce qu'elle comprend un organe sensiblement annulaire (17) se montant sur les voies internes (5, 8), d'autre part en ce qu'elle comprend un organe de positionnement (18) permettant, par rapport aux voies internes (5, 8), le positionnement axial du dispositif de fermeture hermétique (16), et enfin en ce que des organes de fermeture hermétique (21, 22) viennent s'appliquer de façon hermétique contre chacune des voies internes (5, 8). Grâce à cette conception, les dispositifs de fermeture des paliers lubrifiés à la graisse sont plus hermétiques, notamment ans le cas des axes de roues des véhicules à moteur.

Abstract: Lentille ophtalmique produisant un effet correcteur monofocal de la vision avec une profondeur de champ accrue, pouvant être implantée dans l'oeil, placée par dessus l'oeil ou fixée dans la cornée. Cette lentille ophtalmique présente une puissance de base en dioptries adaptée à la correction de la vision au loin, une première zone produisant un premier effet correcteur de la vision et une seconde zone ayant une seconde puissance correctrice de la vision. La seconde zone est située radialement à l'extérieur de la première. La première zone présente une puissance correctrice pour la vision rapprochée et la seconde présente une puissance correctrice pour la vision éloignée. La valeur maximale en dioptries de la première zone se situe environ 0,7 dioptries au-dessus de la puissance en dioptries de base, et la valeur minimale en dioptries de la seconde zone se situe à environ 0,5 dioptries en dessous de la puissance de base. La première zone sert à concentrer la lumière à une première distance prédéterminée de la rétine de l'utilisateur, et la seconde zone sert à concentrer la lumière à une seconde distance prédéterminée de la rétine de l'utilisateur. La seconde distance prédéterminée est approximativement opposée et égale à la première distance prédéterminée. Une troisième zone, sensiblement similaire à la première, est située radialement à l'extérieur de la seconde zone et une quatrième zone, sensiblement similaire à la seconde, est située radialement à l'extérieur de la troisième. La troisième puissance correctrice de la troisième zone est sensiblement la même que la première puissance correctrice de la première zone et la puissance correctrice de la quatrième zone est approximativement la même que la seconde puissance correctrice de la seconde zone.

Abstract: In a hybrid vehicle including an engine 61 and
a generator-motor 43 as a drive source, a driving force
transfer system 60 is constituted by disposing a
centrifugal clutch 62, a transmission 48 and a one-way
clutch 65 in a driving force transfer path from the engine
61 up to a driving force joining point 53 where the driving
force of the generator-motor 43 and that of the engine 61
join together. 
     By switching the generator-motor into the motor,
the vehicle can be moved forward by both engine and
generator-motor, while by switching the generator-motor
into the generator, batteries can be charged while electric
power is generated by the engine, and the vehicle can be
moved forward or backward by the generator-motor alone with
the engine OFF. Thus, the vehicle can be moved backward
using the generator-motor as a drive source, and batteries
can be charged through the generator-motor using the engine
as a drive source.

Abstract: A mechanical optical switch having enhanced alignment uses two optical fiber
structures (40,35) containing corresponding arrays of optical fibers (42,37) fixed to first and second
substrates cleaved from a common substrate. In an exemplary embodiment, an array
of optical fibers is fixed to a common substrate substantially parallel to one another.
The resulting structure is cleaved across the optical fiber array to produce cleaved
structures. The enhanced optical fiber alignment at the cleaved edges is provided by
securing particular respective surfaces of the cleaved substrates to surfaces of two
bases aligned in a common plane. Such enhanced alignment occurs in a direction
normal to the plane of the surfaces of the bases. Alignment of the optical fibers in a
direction parallel to this plane and optical connections between optical fibers of the
respective structures occurs by moving the second cleaved structure relative to the first
cleaved structure in a direction along the cleaved edges.
