A method and apparatus for generating one or more transfer functions for converting waveforms. The balun structure includes primary and secondary metal windings at separate layer interfaces. In various embodiments, the complementary electronics are packaged in an ASIC with output pins similar to that of a smart card, which may include a properly equipped protocol processor for de-packaging and packaging data being inputtedoutputted in accordance with selected IO protocols. Either alarms are set off or treatment occurs or both, when deviations are observed. In another example, an assembly tool provides a stage to orient the capacitive plate and support structure within the ferrule at a desired depth.
