Abstract: A technique is provided for visualizing a volume of interest, such as may be acquired by a tomosynthesis imaging system. The technique provides for the use of one or more weighting functions, such as depth-dependent weighting functions, in the determination of pixel values in a volume rendering. The weighting functions may modify, for example, an intensity determination for a pixel, either directly or by modifying other contributing functions, such as for determining occlusion effects. The volume rendering may then be displayed for review by a technologist or clinician.

Abstract: Methods of manufacturing memory devices and memory modules comprising memory device. Specifically, respective operating current values may be measured and/or stored on a plurality of memory devices. More specifically, the operating current values may be stored in programmable elements, such as antifuses, on memory devices. The memory devices may be coupled to a substrate to form a memory module. A non-volatile memory device may be coupled to the substrate. The operating current values may be read from the programmable elements and stored in the non-volatile memory device. Once the memory module is incorporated into a system, the programmable elements or non-volatile memory may be accessed such that the system can be configured to optimally operate in accordance with the operating current values measured for each memory device in the system.

Abstract: In accordance with one embodiment, there is provided a welding torch nipple for coupling a welding cable and neck assembly to one another. The exemplary nipple includes two hollow tubes: an inner tube disposed in an outer tube. The inner tube includes features that facilitate mating with a welding cable and the outer tube is configured to receive a neck assembly. A dielectric layer disposed between the inner and outer tubes electrically isolates the outer tube from the inner tube, thereby protecting a user from electrical shock, for instance. The dielectric layer includes a stem portion that extends radially into the outer tube, blocking axial separation of the outer tube and the dielectric layer.

Abstract: In accordance with one exemplary embodiment, there is provided a welding torch that includes features facilitating aligned assembly of various components of the welding torch with respect to one another. For example, the welding torch includes a nipple that carries a pin member extending from both an inner peripheral surface and an outer peripheral of a sleeve of the nipple. This pin engages with a slot on a coupling member and a slot on a neck assembly, thereby facilitating proper alignment of the neck assembly, coupling member, and nipple with respect to one another. Moreover, the engagement between the pin member and the slots block pivotal displacement of neck assembly, coupling member, and neck assembly with respect to one another. Advantageously, the use of a single pin member for both slots presents a more judicious construction, leading to reduced manufacturing costs, for instance.

Abstract: In accordance with one aspect of the present technique, a method of reducing pollutant emissions from a compression-ignition engine is provided. The method includes adjusting timing of fuel injection into a combustion chamber of a piston-cylinder assembly of the compression-ignition engine. The method of adjusting timing of fuel injection includes indexing a drive mechanism intercoupling a camshaft to a crankshaft by at least one tooth away from a standard position. The method of adjusting timing of fuel injection further includes adjusting a pre-stroke of a plunger of a fuel injector assembly.
Abstract: The present technique selectively handles image data, which is decomposed into a plurality of resolution levels. The image data may be retrieved in order of progressively higher resolution levels for display in a viewport. Initially, the image data may be displayed in the viewport at a relatively lower one of the plurality of resolution levels. As a user desires higher resolution displays of all or part of the image, one or more of the progressively higher resolution levels may be retrieved and scaled to fit the viewport. Accordingly, the present technique handles the data more efficiently by accessing the image data in blocks corresponding to the plurality of resolution levels, rather than accessing the entirety of the image data. A scaling threshold also can be used to signal the need for a next higher level of the plurality of resolution levels.

Abstract: In etching trench isolation structures, a pad oxide or sacrificial oxide may be formed with substantially the same (or higher) etch rate as the trench filler. Because the etch rate in the trench area is substantially similar to (or less than) the etch rate in the non-trench area, similar amounts of material are removed in both the trench area and non-trench area in a subsequent etching process. Consequently, formation of notches and grooves in the semiconductor structure is minimized. A sacrificial oxide layer may be made by depositing a layer of a suitable material on the surface of a semiconductor structure. By depositing a sacrificial oxide layer instead of thermally growing a sacrificial oxide layer, grooves and the notches in the trench areas are filled by the deposited material.
Abstract: A method and system for detecting weld signatures from an ultrasound scan data obtained from scanning a pipeline is provided. The method includes a step for mapping multiple amplitude responses from the ultrasound scan data, each amplitude response being representative of a respective sensor signal. Continuous amplitude responses are located from the amplitude responses and corresponding signatures are identified for the continuous amplitude responses. The method also includes a step for tagging the corresponding signatures as weld signatures.
Abstract: A compliant seal assembly for a rotating machine is provided. The seal assembly includes a static member, a movable member and a biasing member. The static member is rigidly fixed to the machine at its fore and aft ends. The movable portion has a first sealing surface configured to seal against a rotating member and a rear surface, which may be exposed to a fluid pressure to urge the first sealing surface toward a sealing position with the rotating member. The static and the movable members further include sealing surfaces at their fore, aft and end faces to seal against leakage of gas between the static and the movable members. The biasing member is configured to support the movable member on the static member and to urge the movable member away from the sealing position so as to reduce force on the rotating member during contact of the rotating member with the first sealing surface of the movable member.

Abstract: Techniques for forming devices, such as transistors, having vertical junction edges. More specifically, shallow trenches are formed in a substrate and filled with an oxide. Cavities may be formed in the oxide and filled with a conductive material, such a heavily doped polysilicon. Vertical junctions are formed between the polysilicon and the exposed substrate at the trench edges such that during a thermal cycle, the heavily doped polysilicon will out-diffuse doping elements into the adjacent single crystal silicon advantageously forming a diode extension having desirable properties.
