Filed: 1999-07-30
Granted: 2010-07-27
Abstract: An engine is disclosed. According to one embodiment of the present invention, the engine comprises a compressor, and combustor, and an expander. The compressor compresses ambient air. The combustor burns the compressed air, and produces exhaust gases. The expander receives the exhaust gases from the combustor, and expands the exhaust gases. The compressor may be a gerotor compressor or a piston compressor having variable-dead-volume control. The expander may be a gerotor expander or a piston expander having variable-dead-volume control. In another embodiment, an engine comprises a piston compressor, a combustor, a piston expander, and a pressure tank. The piston compressor compresses ambient air. The combustor bums the compressed air, and produces exhaust gases. The piston expander receives the exhaust gases from the combustor, and expands the exhaust gases. The pressure tank receives and stores the compressed air from the compressor. In another embodiment, a gerotor compressor or a gerotor expander comprises an inner gerotor, and an outer gerotor. The inner gerotor and the outer gerotor are driven so that they do not touch. The gerotors may be cantilevered or non-cantilevered.

Abstract: Ce système de valeur stockée hétérogène permet une interopérabilité entre un certain nombre de marques de cartes de paiement privatives à structures de redevances différentes. L'argent électronique obtenu à l'origine grâce à une marque de carte de paiement spécifique est reconsolidé au niveau du règlement, garantissant une reddition de compte pertinente pour ces redevances. Le système peut accepter un flux isolé, l'argent électronique circulant d'un dispositif de chargement (2) vers une carte de paiement (8) et donc d'une carte de paiement (8) vers un point de vente (6) vers le règlement (7), l'argent électronique circulant alors dans une carte de paiement uniquement depuis le dispositif de chargement. Le système peut également accepter une circulation de l'argent électronique, le rechargement se faisant par conséquent par renvoi de l'argent électronique à une carte de paiement (8) comme monnaie d'une transaction de facturation au niveau du point de vente (6). Des cartes de paiement possédant plus d'une fonction de facturation peuvent être acceptées, le client pouvant préciser quelle fonction de facturation sera utilisée pour acquérir l'argent électronique.

Title: Non-contact or non-contact hybrid smart card for limiting risks of fraud
Inventor: KAYANAKIS GEORGES
IPC: H01L23/32
Filed: 2000-11-28
Granted: 2010-01-05
Abstract: The invention relates to a contactless or hybrid contact-contactless smart card, including an antenna on a support, this antenna being formed by at least one turn of electrically conductive ink which is screen printed on the support, two card bodies 24 on each side of the support, each of the card bodies consisting of at least one layer of plastic material, and a chip or module 26 connected to the antenna. The support is made of paper and features cutouts 22 in each corner at which the two card bodies are welded together, thus giving its capacity to delaminate, when the card is bent, at the location where the forces were generated, which highlights any act of deliberate damage a posteriori as the card retains the traces of the bending, and represents a countermeasure against fraud.

Abstract: Cette invention concerne un inhalateur régulé qui s'utilise avec un récipient (25) rempli d'aérosol sous pression et qui est commandé de préférence par la respiration. Une précharge (460) suffisante est appliquée sur la soupape intérieure d'aérosol pour déclencher la libération d'une dose déterminée, mais une force résistante pneumatique (130) vient contrer cette précharge. L'inhalateur comprend un dispositif de libération (520), qui, lorsqu'il est sollicité, relâche la force résistante et permet à la précharge d'actionner la soupape d'aérosol (135). Est alors libérée une dose déterminée que le patient peut inhaler. La force résistante pneumatique est créée par une zone de pression négative (600) définie en partie par une membrane (440). Cette membrane (440) comprend un disque central (441) fait d'un premier matériau "A" à la rigidité assez importante, et un anneau périphérique relié par la partie courbe d'un second matériau "B" à rigidité relativement faible.

Abstract: L'invention concerne un procédé de synthèse de nanocristaux colloïdaux au moyen d'oxydes métalliques ou de sels métalliques utilisés comme précurseur. Ces oxydes métalliques ou ces sels métalliques sont combinés avec un ligand, puis chauffés en combinaison avec un solvant coordinant. Après le chauffage, lesdits oxydes ou sels métalliques sont transformés en complexes métalliques solubles stables. Ces complexes métalliques sont formés par des espèces cationiques se combinant avec les ligands et/ou le solvant coordinant. Finalement, on introduit un précurseur chalcogène élémentaire, tel que Se, Te ou S, dans le complexe métallique soluble en vue d'opérer la formation de nanocristaux à une vitesse régulée. L'utilisation de CdO comme précurseur de cadmium permet de produire des nanocristaux CdSe, CdTe et CdS de haute qualité. Le présent procédé permet de réguler la taille, la composition granulométrique et la forme (points ou tiges) des nanocristaux pendant leur développement. Par exemple, on peut obtenir des nanocristaux pratiquement monodispersés sans séparation par criblage. Par ailleurs, ledit procédé constitue une évolution substantielle vers une technique de chimie écologique destinée à la synthèse de nanocristaux semi-conducteurs de haute qualité.
