  • Patent number: 11977412
    Abstract: A variety of improvements to docking systems for portable computing devices are disclosed. For example, improved techniques for maintaining a data connection between a base portion of the docking system and a case portion of the docking system are disclosed. As an example, the docking system can include improved magnetics that help maintain the data connection between the base portion and the case portion, even during rotational movements of the case portion relative to the base portion. Further still, examples are described where the detection of a docking action between the case portion and the base portion can trigger any of a number of responsive actions.

  • Patent number: 11365608
    Abstract: A method of moving a string assembly within a wellbore is disclosed. In some embodiments, the method comprises moving the string assembly within the wellbore; obtaining surface data regarding at least one parameter associated with moving the string assembly within the wellbore over a range of depths; modeling the at least one parameter over the range of depths for a plurality of assumed friction factors to obtain modeled data for each assumed friction factor; calculating a derivative of the surface data over the range of depths; calculating a derivative of the modeled data over the range of depths; comparing the derivative of the surface data to the derivative of the modeled data; determining one or more local friction factors for the range of depths based on the comparison; and adjusting at least one string assembly operating parameter based on the one or more local friction factors.

  • Publication number: 20150083495
    Abstract: Systems and methods for vertical depth control during extended-reach drilling operations include extending a length of a wellbore to locate a directional drilling assembly at a selected location within an intermediate portion of a subsurface region and detecting a detected pressure at the selected location. The methods further include determining an expected pressure at the selected location, comparing the detected pressure to the expected pressure, and adjusting an orientation of the directional drilling assembly based, at least in part, on the comparison. The expected pressure may be determined based, at least in part, on a reference pressure that was detected previously within the intermediate portion of the subsurface region. The systems include extended-reach drilling operations and/or directional drilling assemblies that include and/or are associated with controllers that are programmed to perform the methods.

  • Patent number: 5046022
    Abstract: Systems and methods for performing tele-operations with the active assistance and supervision of a cognitive agent, such as a human being, who generates a future path plan in real time for immediate use by an automated on-line controlled agent, such as a work robot or other manipulator, are disclosed. The systems and methods may employ a visual display to present images of the controlled agent, of a foward simulation of the controlled agent, and of the future path plan being generated to enable a human operator to assess and control the on-going activity. The system simultaneously operates the controlled agent and produces the forward simulation and path plan, all under real time conditions. The cognitive agent, display and forward simulation equipment may be at one location and the controlled agent and its controller at another remote location.

  • Patent number: 4793813
    Abstract: A rapidly responsive, computer-based education system is described wherein a large central computer which is adapted to store and execute educational software and to provide a high speed data output stream of multiplexed data frames, communicates with a plurality of remotely located, keyboard actuated display terminals. Communications are accomplished in the forward channel via a satellite link with reverse channel communications being via one or more dedicated telephone lines. The forward channel satellite link is able to accept data at multi megabit rates and to service tens of thousands of user terminals per satellite transponder. The reverse channel telephone line, while only able to accept data rates in the kilobit per second range, accommodates outputs from hundreds of user operated terminals because of the low data rates generated by user operated terminals.
