Abstract
The flooring structure of this invention controls electrostatic charges. The normal presence of moisture will not affect the floor structure's ability to control electrostatic charges. A moisture detector circuit will, however, indicate the presence of moisture, and can activate means for drying this moisture. The resistance of the flooring structure can be adjusted so that electrostatic charges are dissipated at different rates. Multiple floor structures with different resistance values can be placed side by side. Improper grounding of the flooring structure can be detected and corrected, and the resistance of the flooring structure system can be determined.
