Patent CA-2307931-A1 (CA)
Title: Medical dye delivery system
Inventor: URRUTIA HECTOR
IPC: A61M5/40
Filed: 2000-05-09
Abstract: A medical dye delivery system includes a medical dye container and a syringe for withdrawing the medical dye from the container and delivering the dye to a patient. A valve is disposed in the system having an inlet in flow communication with the medical dye container and an outlet in flow communication with the syringe. The valve includes a housing defining a flotation chamber with a valve seat and a flotation member disposed therein. The flotation member seals off the valve seat opening upon medical dye depletion, forcing any remaining fluid flow through a bypass channel that provides restricted flow to provide a tactile warning to the operator of the system that the medical dye container is depleted, yet allow the operator to purge remaining dye from the system. In a preferred embodiment, the flotation member has first and second portions, with a density of the second portion being greater than a density of the first portion. The density of the second portion is sufficient to close against the valve seat, yet is still capable of being suspended above the valve seat when the flotation member floats in the volume of medical dye.

IPC: H01Q15/08

Abstract: A miniature phased array antenna system employs a substrate having a high dielectric constant. A plurality of antenna elements are located on a surface of the substrate, and a superstrate having a high dielectric constant covers the antenna elements. The dielectric constant, thickness, and shape of the superstrate enable it to act as a dielectric lens for controlling the phase relationship of a signal received by the antenna elements. The design of the superstrate dielectric tens permits a reduction in the physical spacing between the antenna elements while maintaining spatial diversity in phase between signals arriving from different directions.  Thus, the antenna array may be significantly smaller than conventional phased array antennas while maintaining a similar phase relationship to that achieved using conventional phased array antennas. Electronic circuitry coupled to each of the plurality of antenna elements applies complex weights to received signals prior to a summation thereof in order to reconstruct a desired signal and to deconstruct an undesired signal. SAW filters employed in the electronic circuitry are temperature controlled to maintain group-delay and phase-offset stability.

Abstract: L'invention concerne un procédé et un système de traitement de comptes permettant de fournir des paramètres spécifiques de pré-autorisation pour des catégories d'opérations qui seraient totalement interdites si l'on disposait uniquement de paramètres généraux d'autorisation. Dès l'établissement d'un compte, certaines catégories d'opérations nécessitent une autorisation spécifique avant que l'opération soit approuvée comme le demande le commerçant (206). Un émetteur de compte fournit un service aux titulaires d'un compte qui permet au directeur des comptes (202) de spécifier indépendamment les paramètres nécessaires pour approuver l'opération au sein de ces catégories. Le directeur des comptes (202) peut aussi spécifier un identificateur d'opération comme par exemple une commande, un ordre de travail ou un numéro de déclaration de sinistre de manière à les associer aux paramètres d'opération requis. Après l'approbation de cette autorisation spécifique requise par l'opération, l'agent d'autorisation (212) transmet les informations propres à l'opération comme par exemple la quantité d'opérations et les informations commerciales avec l'identificateur d'opération attribué auparavant par le directeur des comptes (202) et ceci pendant le traitement des factures. Cette association facilite le rapprochement des comptes pour des opérations de paiement effectuées notamment avec une carte de crédit.

Abstract: L'invention concerne une fraise (70) servant à pratiquer un trou (H) sur une surface (S). Cette fraise comporte une tête de coupe (22) comprenant une cavité (24) et, sur une extrémité, une surface de coupe (36) servant à pratiquer le trou. Un passage (15) destiné à recevoir une mèche (12) s'étend de la cavité à la surface de coupe. La mèche est conçue pour être entraînée par rotation et créer un mouvement axial relatif dans la cavité entre une première position dans laquelle la mèche s'étend dans le passage et une extrémité coupante de la mèche traverse la surface de coupe, et une seconde position dans laquelle la mèche est au moins partiellement rétractée dans la tête de coupe. Lors de l'utilisation, lorsque la mèche est entraînée par rotation, elle peut être enfoncée, alors qu'elle se trouve dans la première position, dans la surface afin d'y percer un trou de guidage jusqu'à ce que la tête de coupe viennent en contact avec la surface. La mèche peut alors être déplacée, selon un mouvement axial relatif, dans la tête de coupe, de sorte qu'elle passe à la seconde position. Une nouvelle rotation de la mèche fait ensuite tourner la tête de coupe, de façon à pratiquer le trou.
