Abstract: A tubular goods connection for releasably coupling tubular members includes: a coupling having a first internal wedge dove-tail thread formed within a longitudinal bore of the coupling and a second internal dove-tail wedge thread; a first tubular member having a first mating external vanishing dove-tail wedge thread extending from a first proximal pin end face; and a second tubular member substantially identical to the first tubular member; wherein when the first and second tubular members are made-up into the coupling using a predetermined recommended optimum torque, a distance D between the first pin end face and the second pin end face is in the range of 0 to 10 millimeters and when the distance D is equal to 0 there is contact between the first pin end face and a second pin end face of the second tubular good but there is no axial interference.

Abstract: A method by which threaded sections of oil field pipe are connected to form a coupled and sealed tubular connection having proper sealing positioning at proper make-up torque. A tubular coupling has box ends and an internal mid region which forms interior shoulder regions. A seal ring is received on the mid region and mates with the end faces of the coupling shoulder and with a centrally located groove on the shoulder. The pin ends of opposing sections of pipe are received within the oppositely arranged box ends of the coupling and are made-up to a final, desired make-up position. The final position and amount of squeeze on the seal ring are controlled by utilizing the contact between the pipe pin ends and the shoulder regions of the coupling.

Abstract: In certain embodiments, a sensing and tracking system detects objects, such as user input devices or peripherals, and user interactions with them. A representation of the objects and user interactions are then injected into the virtual reality environment. The representation can be an actual reality, augmented reality, virtual representation or any combination. For example, an actual keyboard can be injected, but with the keys pressed being enlarged and lighted.

Abstract: In some embodiments, a system comprising one or more processors configured to track a location of an input device within a physical environment via a three-dimensional (3D) tracking system, and modify a tracking parameter of the 3D tracking system while tracking the location of the input device based on the determined location of the input device within the physical environment. The input device may be coupled to a virtual reality display system and tracking the location of the location of the input device can be used for interacting with the virtual reality display system.
