Abstract: A smoothness indicator analysis system generates a comprehensive report and a graphic user interface display useful for planning pavement projects and future maintenance of a paved road. The smoothness indicator analysis system includes an information handling system for analyzing elevation information collected and measured by a smoothness indicator. The information handling system may be configured to receive user selections and input parameters through a graphic user interface. Based on the user selections and the input parameters, the elevation information is analyzed and various reports are generated. An amount of paving material required for a given portion of the road surface and the pavement thickness of a given portion of the road surface may be estimated.

Abstract: A hydraulic cylinder assembly includes a transducer having a wand and a wiper assembly, wherein the wiper assembly is positioned a predetermined distance from an end of the wand for providing a desired startup resistance. A tube includes a piston contained therein for actuation between the first end of the tube and the second end of the tube. A rod is operatively attached to the piston. The piston and the rod are movable together between the first and second ends of the tube. The second end of the tube includes the transducer for monitoring the position of the piston with respect to the second cap member. The wand extends into the piston, and the transducer senses the position of the wiper assembly with respect to the wand for monitoring the position of the piston with respect to the second cap member.
