    摘要: Techniques are disclosed for generating a representation of an access control list, the representation being utilizable in a network processor or other type of processor to perform packet filtering or other type of access control list based function. A plurality of rules of the access control list are determined, each of at least a subset of the rules having a plurality of fields and a corresponding action. The rules are processed to generate a multi-level tree representation of the access control list, in which each of one or more of the levels of the tree representation is associated with a corresponding one of the fields. At least one level of the tree representation comprises a plurality of nodes, with two or more of the nodes of that level having a common subtree, and the tree representation including only a single copy of that subtree. The tree representation is characterizable as a directed graph in which each of the two nodes having the common subtree points to the single copy of the common subtree.

    摘要: This invention relates to processes of producing lubricant base oils comprising paraffinic hydrocarbon components that have optimized branching. The lubricant base oils comprising paraffinic hydrocarbon components with optimized branching have low amounts of branching with the branching concentrated toward the center of the lubricant base oil molecules. The lubricant base oils comprising paraffinic hydrocarbon components with optimized branching have low pour points and extremely high viscosity indexes. The invention further relates to processes of producing commercial lubricants comprising the lubricant base oils comprising paraffinic hydrocarbon components with optimized branching from waxy feeds.

    摘要: Apparatus and methods for simulating a sheet source with a line source for determining normalization coefficients for the detectors in positron emission tomography (PET) scanners and single photon emission computed tomography (SPECT) scanners. A line source, oriented perpendicular to the axis of a scanner gantry, is moved along the axis while the detectors are stationary and positioned substantially parallel to the plane in which the source moves. In another embodiment, an axially mounted line source moves parallel to a diameter of the gantry while the stationary detectors are positioned substantially parallel to the plane in which the source moves. In still another embodiment, the line source is stationary and positioned parallel to the gantry axis and off center while the detectors move relative to the line source. A shaped attenuator is placed around the source in this last embodiment.

    摘要: Valve assemblies and valved catheters including pressure sensors, and related methods for treating patients, are disclosed. The valve assembly includes a valve member extending across a first lumen and includes a planar flexible member with an internal slit acting as a valve. The valve assembly further includes a pressure sensor located distally from the valve member and in fluid communication with the first lumen.
