Abstract: A technique facilitates construction of a wire-wrapped screen. A wrapping machine is operated with a sensor, e.g. a camera, positioned adjacent the wrapping machine while wire is wrapped to create the wire-wrapped screen. The sensor is used to obtain data on at least one parameter of the wire-wrapped screen during creation of the wire-wrapped screen. Data is provided to a controller in communication with the wrapping machine to improve the quality of the wire-wrapped screen. For example, data from the images obtained via the camera may be provided to the controller which is configured to determine slot width as the wire is wrapped. The controller is then able to provide feedback in real time to the wrapping machine so as to adjust the wrapping machine for maintaining a desired slot width.

Abstract: A method for machining a workpiece includes using a multi-axis robot to lift a tool head from a magazine. The robot attaches the tool head to an end of a drill tube. The drill tube is then rotated and longitudinally translated to machine the workpiece. The tool head is withdrawn from the machined workpiece longitudinally by moving the drill tube. The robot is used to disconnect the tool head, replace the disconnected tool head into a magazine and withdraw a different tool head from the magazine for attachment to the drill tube.

Abstract: An apparatus, system, and method for mapping a conduit wall, of which the apparatus includes a shaft defining a central longitudinal axis, and a sensor module coupled to the shaft and including an emitter configured to emit a light beam directed at least partially radially with respect to the central longitudinal axis, and a sensor configured to detect a reflected portion of the light beam, such that the sensor module is configured to measure a distance between the conduit wall and sensor module. The apparatus also includes a centralizer coupled to the shaft and configured to position the sensor module at a center of the conduit.

Abstract: The present invention provides a plasma processing apparatus. The apparatus includes a vacuum chamber, a plasma reactor arranged in the vacuum chamber for plasma processing, an RF power source for providing RF signals to the plasma reactor and an RF power transmission unit for transmitting RF signals from the RF power source to the plasma reactor inside the vacuum chamber. The RF power transmission unit includes a transmission line for transmitting RF signals and an outer conductor for shielding the electromagnetic field around the transmission line. The invention can effectively avoid the problem of electric discharge when RF signals transmit in a vacuum chamber, resulting in more security and less transmission power loss.
