Abstract: A mountable storage arrangement includes a mounting frame and a mountable storage device. The mounting frame includes a draw tube and a base member and upright member secured to the draw tube. The base member includes a support member having an axially extending portion and a laterally extending portion. The mountable storage device includes a base portion having a lower frame engaging surface including a recess sized to receive the support member to limit lateral and axial movement of the base portion with respect to the base member. The mountable storage device further includes an upright portion having an attachment feature configured to be secured to a corresponding attachment feature of the upright member to limit vertical movement of the base portion with respect to the base member when the support portion of the base member is received in the base portion recess.

Abstract: An example transition fitting includes a fitting body have a first shoulder, a second shoulder and a compression region extending radially inwardly from the first shoulder and the second shoulder. A fluid conduit is attached to the fitting body about the compression region. The fluid conduit is deformed radially inwardly from the first shoulder and the second shoulder to secure the fitting body in an axial direction along a longitudinal centerline axis of the fitting body. The fitting body is rotatable along a longitudinal centerline axis of the fitting body.

Abstract: An apparatus in accordance with the invention may include a downhole tool and a data transmission path incorporated into the downhole tool. The data transmission path may include one or more contact surfaces providing electrical continuity to the data transmission path. To protect the contact surfaces from corrosion while maintaining electrical conductivity, a coating may be attached to one or more of the contact surfaces. The coating may include any of various materials that increase the corrosion-resistance of the underlying base metal, including but not limited to cobalt, nickel, tin, tin-lead, platinum, palladium, gold, silver, zinc, or combinations thereof.

Abstract: A test apparatus for the measurement of expansion and/or shrinkage of a cement test sample during curing under pressure and temperature conditions that simulate downhole oil well conditions isolates the test sample from a first fixed volume of incompressible pressurized liquid using a flexible barrier that forms a wall of a first chamber in a pressure vessel assembly. The first chamber is sealed by a movable piston. A second pressurizing medium is contained in a second chamber on the opposite side of the piston, and is in fluid communication with a pump, whereby the piston is pressure-balanced between the first and the second medium. The piston moves in a bore of the vessel assembly in response to changes in the volume of the test sample during curing and the amount of linear movement of the piston is detected by a sensor system that measures, correlates and transmits any change in the position of the piston as a change in the sample volume for display and recording.

Abstract: A double shouldered downhole tool connection comprises box and pin connections having mating threads intermediate mating primary and secondary shoulders. The connection further comprises a secondary shoulder component retained in the box connection intermediate a floating component and the primary shoulders. The secondary shoulder component and the pin connection cooperate to transfer a portion of makeup load to the box connection. The downhole tool may be selected from the group consisting of drill pipe, drill collars, production pipe, and reamers. The floating component may be selected from the group consisting of electronics modules, generators, gyroscopes, power sources, and stators. The secondary shoulder component may comprises an interface to the box connection selected from the group consisting of radial grooves, axial grooves, tapered grooves, radial protrusions, axial protrusions, tapered protrusions, shoulders, and threads.

Abstract: A whole-body mathematical model (10) for simulating intracranial pressure dynamics. In one embodiment, model (10) includes 17 interacting compartments, of which nine lie entirely outside of intracranial vault (14). Compartments (F) and (T) are defined to distinguish ventricular from extraventricular CSF. The vasculature of the intracranial system within cranial vault (14) is also subdivided into five compartments (A, C, P, V, and S, respectively) representing the intracranial arteries, capillaries, choroid plexus, veins, and venous sinus. The body's extracranial systemic vasculature is divided into six compartments (I, J, O, Z, D, and X, respectively) representing the arteries, capillaries, and veins of the central body and the lower body. Compartments (G) and (B) include tissue and the associated interstitial fluid in the intracranial and lower regions.

Abstract: A system and method of modeling a circulatory system including a regulatory mechanism parameter. In one embodiment, a regulatory mechanism parameter in a lumped parameter model is represented as a logistic function. In another embodiment, the circulatory system model includes a compliant vessel, the model having a parameter representing a change in pressure due to contraction of smooth muscles of a wall of the vessel.

Abstract: The invention is a seal system for a coaxial cable and is placed within the coaxial cable and its constituent components. A series of seal stacks including load ring components and elastomeric rings are placed on load bearing members within the coaxial cable sealing the annular space between the coaxial cable and an electrical contact passing there through. The coaxial cable is disposed within drilling components to transmit electrical signals between drilling components within a drill string. The seal system can be used in a variety of downhole components, such as sections of pipe in a drill string, drill collars, heavy weight drill pipe, and jars.

Abstract: An x-ray densitometry system provides improved analysis of bone images taken of a patient over a course of time by comparing the images to deduce positioning errors and/or to correct positioning errors for improved quantitative assessment of the bone.

Abstract: The invention is a system for transmitting data through a string of downhole components. In accordance with one aspect of the invention, the system includes a plurality of downhole components, such as sections of pipe in a drill string. Each component has a first and second end, with a first communication element located at the first end and a second communication element located at the second end. Each communication element includes a first contact and a second contact. The system also includes a coaxial cable running between the first and second communication elements, the coaxial cable having a conductive tube and a conductive core within it. The system also includes a first and second connector for connecting the first and second communication elements respectively to the coaxial cable. Each connector includes a conductive sleeve, lying concentrically within the conductive tube, which fits around and makes electrical contact with the conductive core.

Abstract: The invention provides a method and apparatus for combining two or more risk models to create a risk model with wider scope than its constituent parts. The method insures that the newly formed risk model is consistent with the component models from which it is formed.

Abstract: A robust transmission element for transmitting information between downhole tools, such as sections of drill pipe, in the presence of hostile environmental conditions, such as heat, dirt, rocks, mud, fluids, lubricants, and the like. The transmission element maintains reliable connectivity between transmission elements, thereby providing an uninterrupted flow of information between drill string components. A transmission element is mounted within a recess proximate a mating surface of a downhole drilling component, such as a section of drill pipe. To close gaps present between transmission elements, transmission elements may be biased with a “spring force,” urging them closer together.

Abstract: Disclosed are an apparatus and a method for remote recovery of inaccessible data on computer storage devices. The method comprises the steps of (1) establishing a communications link from the local computer containing the storage device requiring recovery of data to a remote data recovery computer operated by a technician; (2) allowing the remote technician to interact as though seated in front of the local computer yet having access to all software programs which are resident at the technician's computer, and (3) enabling the remote technician to diagnose and rectify the data loss.
