A microprocessor-controlled high voltage sensor circuit controls resonant operation of an induction coil\u2014capacitor circuit. Hot work includes such things as welding, torch cutting, grinding and the like. A dampening fluid is filled within the indicator case as well, and acts to reduce the possibility of misalignment by reducing wobble of the angle indicator as a ship wheel is rotated. In this way the shutting down operation does not disturb the sensing operation. The release handle cooperates with the first retaining means and the second retaining means via an arm linkage to hold and release the lightweight windshield wiper system. In accordance with one embodiment of the invention, the roadway system comprises a plurality of ground-based hybrid solar-wind energy generating devices, one or more roads, and a roadway system electricity grid.
