The cache is not at the published coords.
Solve a hopefully simple and fun riddle to be rewarded with the cache coordinates. The hide itself is likely considered a park & grab cliche among some in the geocaching community. Dear reader, I'll let you be the judge.
This cache is dedicated to a brilliant pioneer in his field of endeavor. I'm confident every cacher that finds this hide has tuned in to his work. The vast majority of folks may be blissfully unaware they'd done so; and continue to do so. It's my sincere intent that once you solve this puzzle you'll resonate some understanding. Let's filter through the fog of time to tune in to what you seek. You may come across some static when researching this topic. To improve your success for solving this mystery I suggest one discriminate towards a US bias.
Critically look at this deliberately rough hand drawn block diagram. Use it to answer two challenge questions below;

What is the general name given for the design in the diagram? It is one word.
What is the surname of the person who invented it? It is one name.
