Title: Filter flush system and methods of use
Inventor: TSUGITA ROSS S
IPC: A61F2/82
Filed: 2000-08-03
Granted: 2008-12-09
Abstract: A filter flush system for temporary placement of a filter in an artery or vein is disclosed. The system typically includes a guidewire insertable within a guiding catheter, which has an occlusion balloon disposed about its distal end. The guidewire has an expandable filter, which can be collapsed to pass through a lumen and distal port of the guiding catheter. The lumen is adapted to receive a variety of endovascular devices, including angioplasty, atherectomy, and stenting catheters. Fluid medium or blood can be infused through the lumen of the guiding catheter to flush embolic material or mobile plaque generated during the endovascular procedures toward the expanded filter deployed downstream from the region of interest. Methods of using the filter flush system to entrap and remove embolic material from the vessel are also disclosed.

Title: Media access control protocol with priority and contention-free intervals
Inventor: YONGE LAWRENCE W III
IPC: H04J11/00
Filed: 2001-08-02
Granted: 2017-04-11
Abstract: An access contention scheme having both multi-level priorities and a contention-free access indicator 130 for use by a station 12 in a network of stations 10. A station 12 having a frame to transmit determines from a detected contention control indicator 130 if it is permitted to contend for access to a transmission medium14 during a contention period 290. The station 12 determines if the contention control indicator 130 indicates a contention-free access and, if the contention control indicator 130 indicates a contention- free access, the station 12 determines if a channel access priority level associated with the frame to be transmitted is higher than a channel access priority level 144 associated with a last transmitted frame. If so, the station 12 detects whether any station in the network of stations intends to contend for access to the medium 14 at a channel access priority level that is higher than the channel access priority level associated with the frame to be transmitted. If so, the station 12 defers contention for access.

Abstract: A method is disclosed for determining a diameter of a wellbore. The method includes inducing an electromagnetic field in the wellbore and a formation surrounding the wellbore from a first location along the wellbore. At a first time, a phase is measured, with respect to the field at the first location, of a signal induced by the electromagnetic field at a second and at a third location axially spaced apart from the first location and from each other. The measuring is repeated at a second time, and a resistivity of the formation, and the wellbore diameter at the first time and at the second time are determined from the measurements of phase made at the first and at the second times. Any ambiguity in the resistivity is resolved by using resistivity determined from the measurements made at the first time.

Title: Method for reducing test cycle time and for improving measuring accuracy at a leak testing process
Inventor: LEHMANN MARTIN
IPC: G01M3/32
Filed: 1990-01-23
Granted: 2003-10-14
Abstract: The present invention relates to a method and apparatus for reducing the test cycle time and for improving the measuring accuracy of a leak testing process of a container. The process comprises the steps of providing a pressure difference as an initial predetermined pressure between the exterior of a closed container and the interior of the closed container without destroying the integrity of the container. The pressure exterior to the sealed container is measured for a certain time. This measurement determines the pressure integrity of the closed container. The method also includes the step of minimizing the volume of the exterior of the closed container wherein the size of that volume determines the test cycle tame and the measuring accuracy. The invention further comprises a test chamber which is closable and contains a cavity for introducing the container under test. A means is provided for installing or introducing a pressure difference at an initial predetermined value between the exterior of the container under test and the interior of the cavity. A measuring unit is provided for measuring the pressure value which is dependent on the pressure difference and the leakage of the container. The shape of the cavity is at least substantially geometrically similar to the shape of the container so as to minimize the volume of the cavity outside the sealed container under test.

Abstract: The simultaneous synthesis of diverse organic compounds is performed in stackable modules which are moveable among nesting sites located on work station platforms. The reactor module in- cludes a block adapted to receive an array of tube-like reactor vessels. The vessels are sized to optionally accept porus polyethelyene mircocannisters with radio frequency transmitter tags. Each vessel has a bottom port connected to an outlet tube. A valve block located below the reactor vessels simultaneously controls discharge through the outlet tubes. The valve block includes plates with aligned, relatively moveable sets of rib sur- faces which act through Teflon encapsulated silicone O-ring cord sections to simultaneously close rows of outlet tubes. By first utilizing reactor vessels in one set of 48 positions, out of the possible 52 reactor vessel positions in the reactor block, and then utilizing reactor vessels in the other set of 48 positions and shifting the relative position of the collection plate, a single reactor can be employed to discharge into all of the wells of a standard 96 well microtiter collection plate . The apparatus can be used to perform the entire synthesis or only the final cleavage step of a radio frequency tagged synthesis.

Abstract: This invention provides cyanobacteria as an alternative source of ahas and pds genes for plant transformations and for selectable marking. In particular, it provides for cyanobacteria, for example, Synechocystis, as a source of genes encoding herbicide insensitive proteins, and elements of genes for control of expression in plastids. Nucleic acid fragments, both the acetolactate synthase (ahas) large subunit and the ahas small subunit, were found to provide herbicide resistance. Also, the present invention provides novel Synechocystis mutant phytoene desaturase (PDS) gene conferring resistance to 4'-fluoro-6-[(alpha,alpha,alpha,-trifluoro-m-tolyl)oxy]-picolinamide, a bleaching herbicide. The present invention provides improvements to method involving cyanobacteria for the screening of compounds, including a new high-through-put protocol that is a rapid and cost effective way to identify target site genes.

Abstract: La présente invention décrit un appareil et une méthode de bobinage d'une feuille de fils parallèles sur une ensouple. Le bobineur d'ensouple comporte un support de bobines de fil circulaire et arqué qui alimente chaque fil à un peigne d'alignement par le biais des tubes guides connexes. La distance entre chaque bobine de fil et le peigne d'alignement est essentiellement la même pour toutes les bobines de fil, ce qui égalise ainsi la force nécessaire pour les tirer vers le peigne. Ensuite, la feuille alignée de matériau est préretraitée à l'aide de rouleaux chauffée et embobinée sur l'ensouple. Plusieurs moteurs pas-à-pas à vitesse contrôlée servent à maintenir constante une faible tension dans la feuille pendant le processus de retrait. Après le retrait, la tension de la feuille de fils est accrue alors que la feuille est enroulée sur l'ensouple. Une table tournante qui supporte deux ou plusieurs ensouples est prévue afin de faciliter le remplacement rapide des ensouples lorsque celles-ci sont pleines.
