摘要： Systems and methods to cover sensitive areas of downhole tools including a downhole tool having an outer surface including a first position and a second position on the outer surface of the downhole tool, the outer surface having a sensitive area, a downhole sensitive element positioned along the outer surface of the downhole tool at the sensitive area, a movable cover operatively connected to the downhole tool and movable relative to the sensitive area, a control unit configured to generate an activation signal, and an activation mechanism operable in response to the activation signal, the activation mechanism configured to move the movable cover relative to the sensitive area from the first position to the second position, wherein the movement of the movable cover from the first position to the second position one of increases or decreases a portion of the sensitive area covered by the movable cover.

摘要： A guide for a flexible member includes a stationary member, an articulating member, and an actuating member. The articulating member defines a first lumen. The stationary member, the articulating member, and the actuating member are coupled to one another by one or more arcuate grooves or flanges such that the articulating member pivots relative to the stationary member when the actuating member is moved relative to the stationary member. The stationary member and the actuating member form a second lumen arranged to accommodate the flexible member coextensively in the first lumen and the second lumen.
