Title: Silver vanadium oxide having a fine particle size for improved cell performance
Inventor: PAULOT WILLIAM
IPC: H01M50/466
Filed: 2002-09-19
Abstract: The present invention relates to the use of SVO classified to a particle size of about 25µ to about 75µ as a cathode active material in a lithium electrochemical cell. The cathode electrode is fabricated into an electrode assembly by overlaying it with an anode electrode and an intermediate separator.      The reduced particle size of the SVO material means that a separator of reduced thickness is used, which provides space for more active materials in a casing of a given volume. The electrode assembly is then hermetically sealed in a casing and used as the power source for such devices as implantable medical devices.

Abstract: A placement plan (202) is developed for the placement of radioactive seeds i n a prostrate for brachytherapy. The placement plan (202) is made available to  an intraoperative tracking interface (204) which also shows a live ultrasoun d image (208) of the needle or catheter placement in the prostate. The difference in the x-y plane between the planned and actual locations of the needle or catheter is calculated, and from that difference, the error in position of each seed is calculated (212). The seeds are moved, or the operator changes the number of seeds (220), and the dose is recalculated. A small column of ultrasound images is taken (224), and each seed located in t he column of images is given a confidence level (228). If the confidence level exceeds a threshold set by the operator (234), the dosimetry is recalculated . Periodically throughout the seed placement, fluoroscopic x-rays are taken, a nd the seed coordinates are matched to the x-ray image. Seed locations with low  confidence levels are adjusted based on the x-ray locations, and the dosimet ry is recalculated.

Title: Method and apparatus for combining exhaust gas recirculation and engine exhaust braking using single valve actuation
Inventor: MEACOCK WILLIAM A
IPC: F02D13/04
Filed: 2003-03-27
Abstract: A system for accomplishing engine exhaust braking and exhaust gas recirculation for an engine having an exhaust manifold and a plurality of exhaust valves per cylinder during a four stroke engine cycle is provided. The system includes an actuation device operable to provide valve actuation of a single exhaust valve for an exhaust braking event and an exhaust gas recirculation event. The exhaust valve is not completely closed during the exhaust braking event and the exhaust gas recirculation event. The exhaust braking event includes actuating a single exhaust valve beginning during a second half of a compression stroke and a first half of an expansion stroke, and closing the exhaust valve beginning during a second half of an exhaust stroke. The exhaust gas recirculation event includes reactuating the exhaust valve beginning during a first half of an intake stroke, and closing the exhaust valve beginning during a second half of the intake stroke. Since a single exhaust valve is actuated during the exhaust braking and exhaust gas recirculation events, the overall performance of the vehicle is increased.

Abstract: L'invention porte sur connecteur de fibre optique comprenant un prisme, une ferrule et une lentille asphérique. Le prisme comporte un élément de calage triangulaire doté d'une première surface, d'une deuxième surface et d'une base. La ferrule guide la fibre optique afin que cette dernière soit en contact avec la première surface du prisme. La lentille asphérique est intégrée dans la deuxième surface et positionnée de manière à ce que le prisme puisse réorienter un faisceau lumineux, à un certain angle par rapport à un axe de l'entrée de la source optique, par une réflexion interne totale au moyen de la base de l'élément de calage triangulaire. La lentille asphérique est utilisée afin de collimater le faisceau de lumière réorienté ou de le focaliser avant qu'il ne soit réorienté. Ce dispositif peut par exemple être utilisé à l'intérieur d'un système WDM (multiplexeur en longueur d'onde) afin de multiplexer et démultiplexer plusieurs longueurs d'onde de lumière, au moyen d'une configuration de trajet optique en zigzag et de filtres à couche mince afin de dissocier les longueurs d'onde.

Abstract: Le procédé s'effectue avec un bioréacteur qui contient tout le lisier de por c pour une séquence complète de traitement. Le lisier est agité, oxygéné et fractionné sous form e de microbulles qui contiennent en partie les gaz extraits du lisier. Ces gaz sont aspirés hors du bioréacteur au moyen d'une pompe â vide et diffusés à travers la base en solution dans les épurateurs. Ce qui provoque une réaction chimique par laquelle s'établit un échange moléculaire entre l'élément de la base et les gaz malodorants acides des composés soufrés pour former des sels (carbonate, phénolate etc.). La transformation de la structure moléculaire de ces gaz a pour résultat de rendre inodores les fractions gazeuses traitées. Simultanément, dans les mémes réactions, le s éléments fertilisants retirés du lisier tels l'azote, le phosphore se combinent avec l'élément de la base pour former des sels (phosphate, nitrate). Ce qui témoigne du retrait progressif de l'azote et du phosphore durant le traitement.

Title: Active feed paintball loader with flexible impeller
Inventor: JEZDIMIR MICHAEL
IPC: F41B11/02
Filed: 2003-08-29
Abstract: An impeller for an active-feed paintball loader has resilient arms that engage paintballs in the lower portion (well) of the loader and advance them to and through the outfeed tube. The resilient arms are sufficiently stiff to move unobstructed paintballs located between the arms, and sufficiently flexible to yield when forced against stationary paintballs so as not to rupture the paintball shells, the arms substantially returning to their original shape when the obstruction is removed. Accordingly, when the motor is shut off, the arms will simply flex backward as they encounter stationary paintballs. Should a paintball jam occur in the vicinity of the impeller, the arm(s) can flex around the jammed ball without breaking it, and help to dislodge it so as to clear the jam.

Abstract: Diode devices with superior and pre-settable characteristics and of nanometr ic dimensions, comprise etched insulative lines (8, 16, 18) in a conductive substrate to define between the lines charge carrier flow paths, formed as elongate channels (20) at least 100 nm long and less than 100 nm wide. The current-voltage characteristic of the diode devices are similar to a conventional diode, but both the threshold voltage (from 0V to a few volts) and the current level (from nA to .mu.A) can be tuned by orders of magnitude by changing the device geometry. Standard silicon wafers can be used as substrates. A full family of logic gates, such as OR, AND, and NOT, can be constructed based on this device solely by simply etching insulative lines i n the substrate.
