Forget the patent, the boat guys have been doing this for years, first part 
of the throttle range works the throttle, then at full throttle the second 
part of the throttle works the pipe "trombone" (pipe shortens as the throttle 
is advanced through the last part of the range).  Remember these guys are 
racing and are interested only in full throttle response, be quite a pain to 
set up for pattern.
