Patent number: 7059429Abstract: The present invention provides a drilling assembly and method that is especially useful for a bottom hole drilling assembly for drilling a borehole through an earth formation. In one embodiment, the drilling assembly is preferably comprised of a tungsten alloy which is sufficiently plastic to be able to withstand the bending, torsional, and compressive stresses which occur in a bottom hole drilling assembly. The tungsten alloy weight section may be axially moveable with respect to an outer tubular and when mounted within the bottom hole assembly, acts to place the outer tubular in tension to provide a stiffer bottom hole assembly.Type: GrantFiled: January 21, 2004Date of Patent: June 13, 2006Assignee: Strataloc Technology Products, LLCInventors: Bruce L. Taylor, Richard A. Nichols, Larry G. Palmer, Marvin Gregory

Patent number: 6997271Abstract: The present invention provides a torsional energy control assembly and method for eliminating slip-stick and/or drill bit oscillations comprising axial and/or rotational oscillations. In one preferred embodiment, the assembly permits slippage between an upper portion of the drilling string and a lower portion of a drill string. The rotational control assembly may be installed at any desired position in the drill string. The rotational control assembly could also be utilized as a component of other drilling mechanisms such as a downhole drilling motor. The rotational control permits slippage while drilling for a selected time or selected rotational distance or other criteria to thereby release torsional energy in the drilling string which otherwise may produce damaging slip-stick torsional oscillations such as slip-stick.Type: GrantFiled: May 19, 2004Date of Patent: February 14, 2006Assignee: Strataloc Technology Products, LLCInventors: Richard A. Nichols, Bruce L. Taylor, Larry G. Palmer

Patent number: 6577324Abstract: An audiovisual help documentation system for applications running on a multimedia computer workstation or personal computer includes a graphical documentation interface which allows a user to easily access audiovisual or textual documentation related to the application. A pop-up menu model is used to eliminate complexity. Textual and audiovisual “filmclip” documentation are stored in separate subject-specific files. The documentation menu includes a topic field for indicating a topic for which documentation is available, and a user selectable function associated with the topic field. The topic field is associated with a multimedia data file storing audio and video data streams representing the audio and video documentation for that topic. The documentation menu also includes a user selectable function associated with the topic field for retrieving text related to the associated topic.Type: GrantFiled: June 7, 1995Date of Patent: June 10, 2003Assignee: Compaq Information Technologies Group, L.P.Inventors: Ricky S. Palmer, Larry G. Palmer

Patent number: 6320588Abstract: An apparatus and method for storing and retrieving synchronized audio/video “filmclips” to and from a data file of a multimedia computer workstation includes a storage means for a workstation to store audio and video data as digital data packets to the data file, and retrieval means for the workstation to retrieve audio and video data from the data file. The video data is presented as an image on the display of the workstation, while the audio data is sent to either amplified speakers or headphones. An audio data stream is stored to the data file such that the audio data can be retrieved from the data file and reconstructed into a continuous audio signal. The video data is stored to the data file such that each frame of video data is inserted into the stored audio data stream without affecting the continuity of the audio signal reconstructed by the workstation.Type: GrantFiled: April 18, 1997Date of Patent: November 20, 2001Assignee: Compaq Computer CorporationInventors: Larry G. Palmer, Ricky S. Palmer

Patent number: 6195683Abstract: A video teleconferencing method and apparatus for computer workstations connected by a digital data network includes a transmission source means for a local workstation to send audio and video teleconference data across the network to one or more remote workstations, and, a receiver for the local workstation to receive audio and video teleconference data back from the remote workstations. The local workstation sends teleconference data to each of the remote workstations over a variable bandwidth digital data connection, and each of the remote workstations returns teleconference data back to the local workstation over another variable bandwidth digital data connection. The transmission source means includes a master software process executing on the local workstation, and the receiver includes a slave software process executing the remote workstation.Type: GrantFiled: February 12, 1997Date of Patent: February 27, 2001Assignee: Compaq Computer CorporationInventors: Ricky S. Palmer, Larry G. Palmer

Patent number: 5831666Abstract: A video scaling apparatus and technique for compressing and reconstructing video data sent between multimedia workstations during a video teleconference includes a video data scaling device which scale unscaled video data, having V horizontal lines of H pixels each, to reduce the quantity of horizontal lines and the quantity of pixels along each line. A pixel replication device replicate the received scaled pixels to increase the quantity of horizontal lines to V and the quantity of pixels along each of the horizontal lines to H. The scaling device reduces the quantity of horizontal lines to about V/2, and the quantity of pixels along each horizontal line to about H/2. A received pixel is replicated to replace an adjacent pixel along a line to reconstruct the line. The reconstructed line is replicated to replace an adjacent line. The replicated line is shifted by one pixel relative to the adjacent line from which it was replicated to reduce sharp edges and blockiness.Type: GrantFiled: August 5, 1996Date of Patent: November 3, 1998Assignee: Digital Equipment CorporationInventors: Larry G. Palmer, Ricky S. Palmer
