Inventor: LADSTATTER GERALD
IPC: F21Y103/00
Filed: 2002-10-02
Abstract: A luminaire (1) has means for holding and for electrically connecting a tube-like lamp (2) and a back reflector (4), extending over the length of the lamp (2), which is provided for the purpose of reflecting a part of the light emitted from the lamp (1) counter to a certain emission direction. In the back reflector there are provided through-openings (5) which are provided for the purpose of allowing a part of the light emitted from the lamp (2) to pass through in the emission direction, whereby pot reflectors (6) adjoin onto the through-openings (5) in the back reflector (4) in the emission direction.

Abstract: L'invention concerne un procédé et des dispositifs appropriés pour un fonctionnement stable dans le temps d'un empilement de piles à combustible à membrane alimentées par de l'air et un gaz contenant de l'hydrogène et au moins 100 ppm de monoxyde de carbone, procédé caractérisé en ce qu'il crée une condition d'oxydation au niveau des anodes desdites piles de manière continue et automatique ou de manière séquentiellement discontinue. Selon différentes réalisations de l'invention, on obtient la condition d'oxydation en ajoutant au gaz, contenant de l'hydrogène et du monoxyde de carbone, de l'oxygène produit dans une pile électrolytique intégrée dans l'empilement de piles à combustible, ou en faisant passer de l'air à travers des surfaces poreuses des plaques bipolaires ou encore en utilisant des membranes à vitesse de transporisation élevée, la vitesse d'écoulement de l'air étant régulée dans ces deux derniers cas par réglage de la différence de pression existant entre l'air et le gaz contenant de l'hydogène et du monoxyde de carbone. Selon une autre réalisation du procédé de l'invention, on obtient la condition d'oxydation en court-circuitant séquentiellement les empilements de piles à combustible munis de contacts extérieurs connectés à une unité de commande.

Patent CA-2473006-A1 (CA)
Inventor: SCHENCK JEFF L
IPC: H04M9/08
Filed: 2002-12-17
Abstract: In a speakerphone system, the signal that is directed to a loudspeaker is filtered by a dynamically controllable highpass filter. The filter characteristics are adjusted on the basis of the power of the signal and the degree of recent microphone activity. The filtered signal is a far-talker signal, while the microphone activity is represented as a near-talker signal that includes an echo component as a consequence of loudspeaker-to-microphone coupling. The degree of microphone activity is determined by a subband analyzer. A noise floor estimator may be used to determine the degree to which the near-talker signal is comprised of background noise, so that the noise can be eliminated in the process of controlling the highpass filter

IPC: G02B1/04
Filed: 2003-02-10
Abstract: L'invention concerne un composant moulé ou un article à usage biomédical préparé à partir d'un polymère réticulé non soluble dans l'eau qui lorsqu'il est réticulé et saturé d'eau forme un hydrogel. Ce polymère est préparé de la même manière qu'une composition contenant un diluant non aqueux ajouté au polymère, ce diluant étant présent dans une proportion volumétrique sensiblement égale à la proportion volumétrique de l'eau dans l'hydrogel qui est formé lorsque le polymère est réticulé et saturé d'eau. La composition est fondue dans un moule dans lequel elle est exposée à des conditions entraînant la réticulation par une réaction à laquelle le diluant non aqueux est inerte. La réaction de réticulation produit un gel non aqueux moulé qui est ensuite converti en hydrogel par substitution d'un liquide aqueux tel que de l'eau ou un salin physiologique destinés au diluant non aqueux. L'utilisation d'une composition de moulage dans le traitement consiste presque complètement à réticuler les résultats dans un procédé de moulage donnant lieu à une contraction réduite ou inexistante, et dont l'intégrité dimensionnelle est conservée par formation de l'hydrogel au moyen du diluant non aqueux dans une proportion volumétrique sensiblement identique à celle de l'eau dans l'hydrogel.
