摘要： A latch mechanism includes a power actuator that does not require back driving of the drive train. The latch mechanism includes a latch bolt movable between a primary latched position and an open position. A first pawl secures and releases the latch bolt by moving between a latched position and released position. A release device moves between an engaged position, which allows the first pawl to reach an engaged position, and a released position, which retains the first pawl in its released position. A second pawl moves between an engaged position, which retains the release device in its released position, and a released position, which releases the release device.

摘要： An apparatus includes a jet housing including an inlet and an outlet, and a nozzle within the jet housing for injecting fluid towards the outlet. A filter element is disposed on the inlet, the filter element including openings for preventing particulate larger than a predetermined size from entering the inlet. The jet housing is positioned within a blood vessel, and fluid is injected from the nozzle towards the outlet to create a vacuum at the inlet, thereby causing fluid downstream of the outlet to flow retrograde through the vessel around the jet housing into the inlet. The filter element prevents particulate from entering the inlet, thereby effectively capturing the particulate, which may be aspirated. Alternatively, a filter element is used to filter particulate during a procedure. The filter element everts from a tubular to an everted configuration for capturing particulate.

摘要： A vascular catheter includes a catheter body, an inflatable balloon disposed at the distal end of the catheter body, and an inflation conduit extending from the proximal end of the catheter body to the inflatable balloon. The inflation conduit is disposed on the exterior of the catheter body, minimizing the total cross-sectional area but imparting a non-circular periphery. Catheter whip resulting from the non-circular periphery is reduced by arranging the inflation conduit in a helical pattern over at least a distal portion of the catheter body.

摘要： An atherectomy catheter includes a catheter body having a cylindrical housing at its distal end. The cylindrical housing includes an elongate cutting aperture on one side thereof and a mechanism for severing atheroma which enters within the opening. In a first embodiment, the cutting mechanism comprises a circular cutting blade which is advanced over an elongate guide member which defines a path for the blade. Use of the guide means helps assure that the cutting blade will not be lost from the housing during use. In a second embodiment, a rotatable helical cutting blade is mounted within the housing. In that particular embodiment, the helical cutting blade can serve as the guide member for the circular cutting blade.

摘要： Systems, methods, and devices for determining neutron-gamma density (NGD) measurement of a subterranean formation that is accurate in both liquid- and gas-filled formations are provided. For example, a downhole tool for obtaining such an NGD measurement may include a neutron generator, neutron detector, two gamma-ray detectors, and data processing circuitry. Neutron generator may emit neutrons into a formation, causing a fast neutron cloud to form. Neutron detector may detect a count of neutrons representing the extent of the neutron cloud. Gamma-ray detectors may detect counts of inelastic gamma-rays caused by neutrons that inelastically scatter off the formation. Since the extent of the fast neutron cloud may vary depending on whether the formation is liquid- or gas-filled, data processing circuitry may determine the density of the formation based at least in part on the counts of inelastic gamma-rays normalized to the count of neutrons.

摘要： Systems, methods, and devices are provided to determine an accurate neutron-gamma density (NGD) measurement for a broad range of formations, including low-hydrogen-index or low-porosity formations and formations with heavy elements. For example, such an NGD measurement may be obtained by emitting neutrons into a formation such that some of the neutrons inelastically scatter off elements of the formation and generate inelastic gamma rays. The neutrons and inelastic gamma rays that return to the downhole tool may be detected. Some characteristics of certain formations are believed to affect the fast neutron transport of the formations. Thus, if a formation has one or more of such characteristics, a correction may be applied to the count rate of neutrons, the count rate of inelastic gamma rays, or the neutron transport correction function, upon which the neutron-gamma density (NGD) may be determined.

摘要： A gaming device including a display device having a plurality of award groups and an indicator generator. Each of the award groups includes at least one indicator and at least one award. The indicator generator generates a number of indicators for each of the award groups. The gaming device then indicates the corresponding number of indicators in each of the award columns based on the number of indicators associated with those award columns by the indicator generator. When all of the indicators are accumulated in one or more of the award columns, the gaming device provides the awards associated with those award columns to the player and determines whether to end the game. If the gaming device determines not to end the game, the gaming device resets the indicators in the award columns including the provided wards and enables the player to continue playing the game.
