Patent CA-2331421-A1 (CA)
Title: Depot de matiere radioactive par jet de fluide pour dispositifs de curietherapie
Inventor: WILLIS MICHAEL
IPC: G21K5/02
Filed: 1999-05-04
Abstract: L'invention se rapporte à un procédé et à un appareil permettant d'appliquer précisément une matière radioactive sur un substrat tel qu'un dispositif de curiethérapie. Selon ledit procédé, on dépose sur une surface, au moyen d'une tête d'impression par jet fluide, un fluide radioactif réticulable rapidement sous la forme de points distincts. Ledit appareil comporte une tête d'impression par jet fluide en communication avec une chambre contenant un fluide radioactif devant être appliqué par la tête d'impression. La tête d'impression est commandée par un microprocesseur qui peut recevoir une rétroaction d'une station où l'on mesure la radioactivité associée à un dépôt effectué sur un substrat précédent au sein d'un lot, ce qui permet un ré-étalonnage du système en continu lors de la production du lot de dispositifs imprimés. La compensation de l'atténuation du rayonnement par un boîtier peut également être intégrée à la technique de rétroaction. L'invention se rapporte également à un dispositif de curiethérapie doté d'une surface sur laquelle sont imprimés des points de matière émettant un rayonnement, selon un motif comportant diverses bandes, points ou zones. Les fluides convenant à cette impression au moyen d'une tête d'impression par jet fluide contiennent un liant tel qu'une résine acrylique ou un silicate, ainsi qu'un sel, un composé ou un complexe radioactif dissous dans un solvant résistant aux rayonnements. D'autres fluides contiennent des sels, composés ou complexes radioactifs absorbés sur un porteur microparticulaire, ou des particules élémentaires, dispersé dans un milieu fluide résistant aux rayonnements et réticulable rapidement.

Title: Flexible optical rf receiver
Inventor: O'SHEA RICHARD L
IPC: H01Q1/38
Filed: 1999-07-06
Abstract: An array antenna is constructed of radiators disposed upon a flexible substrate wherein a plurality of receiving circuits connect with respective ones of the radiators for conversion of RF (radio frequency) signals, received by the radiators, are converted into IF (intermediate frequency) signals. The signals outputted by the receiving circuits may be applied to a beamformer for generating a receive beam from the array. The receiving circuits have an elongated flexible form to permit bending of the array to have a desired configuration. All power for operating the receiving circuits and all signal paths to and from the receiving circuits are accomplished via optical fibers. Photocells are provided within the receiving circuits for conversion of optical power to operating electric power. Photodetectors within the receiving circuits provide for conversion of optical reference signal to electrical reference signals. An optical modulator within each of the receiving circuits provides for conversion of an outputted electric signal to an output optical signal for transmission via an output optical fiber. In each of the receiving circuits, a mixer provided for conversion between RF and IF is operative without a bias voltage.

Inventor: ENG JAMES ALAN JR
IPC: F02M25/07
Filed: 2001-03-23
Abstract: Exhaust gas recirculation is provided in a turbocharged diesel engine by adding a separate EGR manifold and a secondary exhaust valve for each combustion chamber that permits passage of exhaust gas from the combustion chamber to the EGR manifold. The secondary exhaust valve is opened during the expansion stroke of the engine cycle and sometime after the combustion process has been completed while the pressure in the combustion chamber is still greater than the pressure in the intake manifold. One or two EGR valves can be opened to admit the high pressure exhaust gas from the EGR manifold into the intake manifold. Decompression braking can be provided by an additional valve between the EGR manifold and the exhaust manifold that is opened to dump the gas from the EGR manifold to the exhaust manifold while the secondary exhaust valve in the cylinder head is opened at the beginning of the expansion stroke of the piston whereby the compressed air in the cylinder escapes before performing work on the piston.
