New type of coil needs a name... OL-DRSSTC 7

Hi All,

I guess my little OL-DRSSTC thing seems to be working well ;-))  But 
"OL-DRSSTC" was "picked fast" for a name because it is easy to find 
in a file search...

But it really needs a "better" name, acronym, or 
abbreviation...  Virtually "all" of "your" PC's microprocessors were 
made with a circuit called the "clampinator" (same time the 
"Terminator" movie came out...) by "me" :o)))  But I have been since 
"told" that I am not good at "making up names" as such names need to 
be explained later to giant groups of people :oD

So I am open to whatever "designator" this sort of new "thing" can be 
known by...  There is still time to "fix" this one :o))

Cheers,

        Terry
