Abstract: A system for a vehicle includes an air conditioning system, a motorized directional air flow control feature, a display, and a controller configured to initiate a variable air flow routine. Initiation of the variable air flow routine prompts execution of a predetermined actuation sequence of the motorized directional air flow control feature such that the direction of air flowing from the air conditioning system into a cabin of the vehicle is varied sequentially by the motorized directional air flow control feature. Initiation of the variable air flow routine further prompts the display to display an air flow graphic having a directional quality that corresponds with the orientation of the motorized directional air flow control feature such that the directional quality of the air flow graphic varies sequentially with the direction of the air flowing from the air conditioning system.

Abstract: Apparatus and method for cleaning the exterior surface of a pipe such as a pipe located in a sub-sea location having a coating of concrete or the like thereabout. The apparatus includes a generally longitudinal frame which supports a carriage for longitudinal traverse therealong. The carriage supports a high-pressure fluid nozzle which is arranged to direct the discharge thereof against the pipe coating which is to be removed. The carriage is arranged for longitudinal traverse along the frame, to thereby direct a high-pressure fluid stream into contact with the surface of the pipe. The frame is also arranged for rotation about the pipe, whereby a section of the pipe can be cleaned about its full circumference by a number of generally longitudinal runs along the pipe section being cleaned. The carriage may also support a wire cutter for cutting any re-enforcing wire after the concrete has been dislodged by the fluid nozzle.
