  • Patent number: 8028239
    Abstract: A management user interface can be generated at run time via subtractive extensible context-based filtering. Definitions of user interface elements can include an indication of appropriate contexts for which the user interface elements are to be shown. Context factors can include application state, external state, surface or element definitions, or some combination thereof. The context-based filtering approach allows definition of user interface elements and user interface surfaces so that appearance of additional elements in the appropriate surfaces can be accomplished without programming. For example, a user interface surface definition can specify categories of user interface elements. At run time, those user interface elements of the category can be chosen for display. When new elements relating to the category are added, the new elements appear when the surface is rendered. Other features include heterogeneous type selection and exact number homogeneous type selection.

  • Patent number: 8007051
    Abstract: In one aspect of the invention, a pick comprises a carbide bolster disposed intermediate an impact tip and a shank assembly. The impact tip comprises a superhard material bonded to a carbide substrate, and the tip is bonded to the bolster opposing a base of the bolster. The shank assembly comprises a central axis, a first end that protrudes into a cavity formed in the base of the bolster, and also an inducible attachment mechanism disposed proximate the first end. The inducible attachment mechanism is adapted to attach the shank assembly to the carbide bolster and restrict movement of the shank assembly with respect to the carbide bolster. The attachment mechanism may restrict movement of the shank assembly in a direction parallel to the central axis.

  • Patent number: 7934570
    Abstract: In one aspect of the invention, a swivel for use in a drilling operation comprises a body with a central bore adapted for threaded connection to a tool string component. At least one electrically conductive medium is rotationally supported within the bore and adapted to rotate with respect to an electrically conductive receiver that is rotationally fixed to and disposed within the body. The electrically conductive medium and the receiver are in electrical communication through an electrically conductive arm that is rotationally fixed to the electrically conductive medium and at least partially disposed within an electrically conductive fluid disposed within a reservoir. The reservoir comprises a rigid shape that is partially filled by the conductive fluid. At least one rotary seal is disposed intermediate the reservoir and the electrically conductive medium. The rigid shape of the reservoir is adapted to prevent the conductive fluid from accumulating around the rotary seal.

  • Publication number: 20100299619
    Abstract: Described is a reusable software wizard component that is invoked to integrate its elements (e.g., logic, pages, data and/or tasks) with elements of a wizard to provide an integrated wizard. For example, the integrated wizard may provide customized wizard functionality yet be efficiently developed by the use of at least some re-useable elements. In one implementation, the reusable software wizard component corresponds to a class having interfaces/functions for getting its data, pages and/or tasks. The selected pages and/or tasks may be integrated with pages and tasks of the wizard in any suitable order. Pages from the reusable software wizard component may be pre-filled with data from the wizard.

  • Patent number: 7831605
    Abstract: Integrated management of local and remote media files. A playlist of media files adapted for rendering by a media player application are located in either a local media library stored at the computer or a remote media library accessible by the computer via a data communication network or both. Media player operations may be performed on the playlist. A first identifier identifies each of the media files in the playlist and a second identifier represents a source of each of the media files in the playlist. A streaming locator defined by the first and second identifiers locates each of the media files in the playlist in the local media library and then in the remote library.

  • Publication number: 20100212884
    Abstract: In one aspect of the present invention, a tool comprises a fluid path defined by a bore formed within a tubular body. A guided sleeve and a reciprocating sleeve are both disposed within the bore. A gearwheel is located on an outer surface of the guided sleeve and at least one pawl located on an inner surface of the reciprocating sleeve. When the reciprocating sleeve translates axially, it rotates in a first direction. As the reciprocating rotates, the at least one pawl pushes the gearwheel and causes the guided sleeve to rotate in the first direction into a new position.

  • Patent number: 7730972
    Abstract: In one aspect of the present invention, a drill bit has a jack element that is substantially coaxial with an axis of rotation of the drill bit and the jack element has an asymmetrical distal end that extends beyond a working face of the drill bit. A turbine is located within a bore formed in the drill bit and a flow valve is actuated by the turbine. The flow valve is adapted to route a drilling fluid in the bore into a porting mechanism adapted to extend the jack element farther beyond the working surface of the drill bit. The turbine is also adapted to rotate the jack element at variable speeds.

  • Publication number: 20100065334
    Abstract: In one aspect of the present invention a hammer assembly comprises a substantially coaxial jack element with a distal end extending beyond a working face of a drill bit. A porting mechanism within the bore comprises a first and second disc substantially contacting along a flat interface substantially normal to the axis of rotation. The first disc is attached to a turbine which is adapted to rotate the first disc with respect to the second disc. The first disc comprises a first set of ports adapted to align and misalign with a second and third set of ports in the second disc. As the first disc rotates, the sets of ports are adapted to route a drilling fluid into a piston chamber where the porting mechanism causes the jack element to repeatedly extend further beyond the working surface of the drill bit at a constant frequency.

  • Patent number: 7661487
    Abstract: A downhole percussive tool is disclosed comprising an interior chamber and a piston element slidably sitting within the interior chamber forming two pressure chambers on either side. The piston element may slide back and forth within the interior chamber as drilling fluid is channeled into either pressure chamber. Input channels supply drilling fluid into the pressure chambers and exit orifices release that fluid from the same. An exhaust orifice allows additional drilling fluid to release from the interior chamber. The amount of pressure maintained in either pressure chamber may be controlled by the size of the exiting orifices and exhaust orifices. In various embodiments, the percussive tool may form a downhole jack hammer or vibrator tool.
