Approximately December 24, perhaps it was 1996, I published an idea on a USENET area (maybe it was SCI.CRYPT) that proposed an idea that clock oscillators used in computers could be frequency-modulated with a long-period pseudo-random (linear feedback shift register) value to smear the output of the signal (and everything that depends on it) over a range of frequencies.Curiously, in early 2007 (When I was at United States Penitentiary, Florence Colorado) I received a letter from a law firm offering me $5,000 for ownership of this idea. (They had apparently figured out who I was, and had traced me down at my then-current address.) I presumed that around that time, there was probably a lawsuit challenging a patent on this matter, and the law firm was doing 'due diligence' looking for ammunition. I counter-offered that if they pay me 1/3 of the value of this idea, I would settle for that. Never heard back from them.Jim Bell
