Abstract: Data graphing methods, articles of manufacture, and computing devices are described. In one aspect, a method includes accessing a data set, displaying a graphical representation including data of the data set which is arranged according to a first of different hierarchical levels, wherein the first hierarchical level represents the data at a first of a plurality of different resolutions which respectively correspond to respective ones of the hierarchical levels, selecting a portion of the graphical representation wherein the data of the portion is arranged according to the first hierarchical level at the first resolution, modifying the graphical representation by arranging the data of the portion according to a second of the hierarchal levels at a second of the resolutions, and after the modifying, displaying the graphical representation wherein the data of the portion is arranged according to the second hierarchal level at the second resolution.

Abstract: A method of forming a component having a plurality of parts constructed from at least two different materials includes forming a first part made from a first material, placing a sandcasting pattern in a sand molding box, filling the sand molding box with sand, removing the sandcasting pattern from the sand molding box, placing the first part in a first portion of a void in the sand with the void formed by the removal of the sandcasting pattern, filling a remaining area of the void with a second material, and allowing the second material to solidify to form a second part.

Abstract: A casting method includes coupling a mold to a crucible, the mold having one or more part-defining cavities and one or more feed passageways. A first rotating of the crucible and mold pours molten metal from the crucible through the one or more feed passageways into the one or more part-defining cavities. A second rotating of the crucible and mold returns molten metal from the one or more feed passageways, while leaving the part-defining cavities filled.

Abstract: Data structures and apparatuses to represent knowledge are disclosed. The processes can comprise labeling elements in a knowledge signature according to concepts in an ontology and populating the elements with confidence values. The data structures can comprise knowledge signatures stored on computer-readable media. The knowledge signatures comprise a matrix structure having elements labeled according to concepts in an ontology, wherein the value of the element represents a confidence that the concept is present in an information space. The apparatus can comprise a knowledge representation unit having at least one ontology stored on a computer-readable medium, at least one data-receiving device, and a processor configured to generate knowledge signatures by comparing datasets obtained by the data-receiving devices to the ontologies.

Abstract: A system and method for extracting and converting data from one or more information sources into a common format. The method comprises receiving the information sources, receiving at least one pattern descriptor selected from a graphical user interface, and receiving one or more templates with each templates having at least one pattern descriptor. The method then proceeds to apply the one or more templates to the information sources. The method generates the plurality of data in a common format by parsing the information sources with the templates. The method stores the data in the common format.

Abstract: An apparatus and method is provided for installing and connecting one or more expansion boards in a computer system while the computer system is being manufactured as well as when a user upgrades or reconfigures the computer system. An expansion board bay for receiving the expansion board is located within the computer system, typically on a circuit board such as the motherboard. A connector module that is separate from the expansion board and the expansion board bay is positioned within the computer system. The connector module is positioned to provide easy external access to a contact portion of the connector module, thereby allowing a user to connect an external data signal line to the connector module. A connector cable operably connects the expansion board with the connector module to establish communication between the data processor and the external data line through the expansion board.

Abstract: A cardiac stimulator lead and sleeve for anchoring the lead at its point of entry into a vein. More particularly, the present invention comprises a helical coil made of a resilient material that is capable of being uncoiled and wrapped around the lead and/or the vein such that it is biased to resume its fully coiled state and thereby frictionally engages the vein and or lead and functions as an anchoring device for the lead.

Abstract: An implantable endocardial lead with a retractable helix. A specialized stylet can be inserted into the lead at the proximal end and passed through the lead to the distal end. Located at the distal end of the lead is a piston supporting the helix. The piston is attached to a coiled trifilar conductor and has an electrode adjacent the helix. Immediately adjacent the piston proximally an additional first short coil of wire is interlocked between the wires of the trifilar conductor, providing a female thread within the conductor. The stylet has a second single strand short coil segment spot welded to the stylet adjacent a distal end thereof. The stylet is rotated to screw the second short coil segment on the stylet into the first short coil adjacent the piston.
