A structure and apparatus is provided for an electrostatic discharge power clamp, for use with high voltage power supplies. The system includes an arrangement of a fluorescent material at the location, wherein the fluorescent material: a) is sufficiently transparent in the absence of ultraviolet light, b) fluoresces when illuminated with UV light, c) and has a shape corresponding to the symbol, and a UV light source configured to illuminate the location with UV light to display the symbol. Any transaction found to be in violation is discarded. The intermediate annular magnetic pole portions are fixedly positioned between the pair of magnetic cylindrical members by fitting a peripheral portion defining the fitting concave portion of the intermediate annular magnetic pole portion into the corresponding fitting groove of the magnetic cylindrical member. The method further includes using the augmented steering wheel angle as a feedback signal to the steering wheel control system and the augmented left and right road wheel angles feedback signals to the road wheels control system. The ultrasonic probe design system includes an interface for inputting statement parameters, insonification requirements, and geometric constraints, with an engine responsive to the interface and configured to determine and provide an optimized transducer geometric design output.
