Question

There is no relation whatsoever....just like the FAQ states. I didn't think it could be any more clear 

His last name is MARK. First name is likely STEPHEN, but most use Steven.

I know the coincidences are close, but there are hundreds of patented toroidal shaped devices out there.

Since we have a patent with his name on it (only audio patents...sorry), we know his last name is not Marks, and he has stated it himself, that if it is not MARK, it is not him.

Based on what SM has posted through Mannix, he is no way related to Berkeley Lab. How many such names one can find in a technology field? Probably a lot. Are you going to say that every single name that sounds like Steven Mark is a case for being suspicious? Maybe, but hardly.
Based on what SM was saying, he is an audio engineer, not a mechanical engineer.

.. Would you also say that the BIG toroid at Berkeley in no way influenced the invention of Steven Mark's little TPU??

How many big toroids can you find? Just search for a plasma reactor. You can find endless number of them. Is each one should be considered having some influence on SM? Maybe, but hardly.

If you search the web for UEC, you can also find all types of companies and I am very sure that there would be at least one person in them named Steven Mark.

It should simply be a limit to speculations about SM personality without having obvious facts instead of just having the same names.
