Abstract: A computer-implemented method and system for navigation and display of 3D image data is described. In the method, a 3D image dataset to be displayed is retrieved and a highlight position is identified within the 3D image dataset. A scalar opacity map is calculated for the 3D image dataset, the opacity map having a value for each of a plurality of positions in the 3D image dataset, the respective value being dependent on the respective position relative to the highlight position, and on the value of the 3D image at the respective position relative to the value of the 3D image at the highlight position. The opacity is applied to the 3D image dataset to generate a modified 3D image view.

Abstract: Systems and methods are disclosed for controlling a downhole tool by encoding a tool control signal in a fluid flow and obtaining a temperature response downhole. In an example, a system for controlling a downhole tool includes a signal transmitter, a signal receiver, and a controller. The signal transmitter is uphole of the tool to be controlled (e.g., at surface) and encodes the tool control signal by varying one or more fluid flow parameters of a fluid flow down a well. The signal receiver is positionable in the well in fluid communication with the fluid flow. The signal receiver detects a temperature response in the fluid flow resulting from varying the one or more fluid flow parameters. A controller controls the downhole tool according to the temperature response.

Abstract: A downhole tool for cleaning a wellbore includes a tool body having a passage therein. A liquid is to flow through the passage of the tool body and have an intermittent flow pattern. An inner sleeve positioned within the tool body includes a recess having a recess pattern. In response to the intermittent flow pattern of the flow of fluid, a shift pin positioned in the recess of the inner sleeve is to traverse through the recess pattern. The downhole tool includes at least one scraper blade. The scraper blade is movable between a retracted position and a radially expanded position. In response to the shift pin traversing the recess pattern of the recess, the scraper blade can be expanded radially outward toward a wall of the wellbore from the retracted position to the expanded position and/or retracted inward away from the wall of the wellbore from the expanded position to the retracted position.

Abstract: A technique for supporting a user of a first device coupled to a second device of a support agent. A current screen image of the first device is sent to the second device. The second device displays the current screen image of the first device. The agent device determines the position of an input icon to be displayed on the current screen image, and the position is sent to the first device. The first device displays an input icon on the current screen image on the first device based on the position. The second device also determines how the user should operate the input icon on the first device. Corresponding operation information is transferred to the first device.
