Abstract: Dimensions of a surface feature are determined by capturing an image of the surface feature and determining a scale associated with the image. Structured light may be projected onto the surface, such that the position of structured light in the captured image allows determination of scale. A non-planar surface may be unwrapped. The surface may alternatively be projected into a plane to correct for the scene being tilted with respect to the camera axis. A border of the surface feature may be input manually by a user. An apparatus and system for implementing the method are also disclosed.

Abstract: The invention addresses ways to protect the free ends of communication lines from debris during downhole connection. A lower assembly, positioned downhole, has a lower connector with a free end of a communication line. An upper assembly is moved downhole and has an upper connector. A reciprocating member with attached protective cover is mounted for movement on the lower assembly. A second reciprocating member with attached protective cover is mounted for reciprocating movement on the upper assembly. The free ends are connected as the upper and lower assemblies are moved toward one another. Upon disconnection, the upper and lower connectors are moved apart and the reciprocating members return to their initial positions, again protecting the free ends of the communication lines. The covers are preferably biased towards a closed position and return to a closed state upon disconnection.

Central lines are established based on the attenuated lines-of-sight. The locations of central-line intersections are then established. The average of the locations of the central-line intersections is then used to establish the location of the touch event.
