Hi,

SCR HV stacks have been around since the 70's. They have optically 
triggered SCRs now and they have all kinds of odd triggering methods. 
The patent application seemed cool since it seemed to try to trigger 
them even faster. Normally, "BIG" SCRs are not known for much over 60 Hz :D

The application was April 13, 2001 so I guess 'i' will not go after them 
with my usual "plagiarized, steal, and copy at your pleasure" 
Idealogical indealogy protection :D That would be a heck of an area to 
try an push a new patent though anyway... Most was ultra well covered 10 
years before in HVDC... I guess it was worth the $75 bucks just to 
try... Newer technologies might have opened up new holes though. In this 
case, " Withdrawn: 12.04.2006"... BooHoo...

I would worry a LOT more that the SISG is covered be some other patent 
rather than someone 'stealing' it :D I made the SISG up all myself one 
night without any outside help or ideas. But no guarantee's it was not 
thought of before...

As far as "I" am concerned, all my contributions are all totally Public 
Domain.

Maybe, someday... Somebody will patent a patent system that is truly 
patentable... ;D
