The present invention relates to laminated membranes formed by multi-layer processing techniques including alternating layers of thermoplastic urethane and a copolymer of ethylene and vinyl alcohol. A knock-down bar upon the framework knocks down a normally upstanding traffic cone, and a substantially horizontally oriented, substantially conically configured spearing mechanism mounted upon the framework is inserted into the hollow interior of the traffic cone. An algorithm including the test software subroutine then generates an output command based on the value of the dummy parameter.
