Abstract: A vehicle having a tailgate configured to move between retracted and extended positions is disclosed. The vehicle includes a first detection unit, a second detection unit, a third detection unit and a control unit. The control unit obtains a first input from the first detection unit and determines whether the tailgate is in extended position. The control unit further obtains a second input and a third input from the second and third detection units respectively, when the tailgate is in the extended position. Responsive to obtaining the second and third inputs, the control unit identifies a tailgate extended orientation. In addition, the control unit detects an obstacle presence in a vehicle rear side proximity and calculates a calibrated distance between the obstacle and a tailgate top side, based on the tailgate extended orientation. The control unit notifies a vehicle user when the calibrated distance is less than a threshold.

Abstract: A system and a method embodiment or automatic inspection of branch wells is provided. An exemplary system includes a scanning head including an ultrasonic probe, wherein the ultrasonic probe includes a convex crystal. A track is mounted to a branch pipe welded to a main pipe, wherein the scanning head mounts to the track, and wherein the scanning head moves the ultrasonic probe along the track. The system includes a controller configured to display an image based on data provided from the ultrasonic probe.
