I have looked for years but have never been able to find any reading material
on these methods.
If anyone can direct me to a book or other source from Hazeltine about this topic, I would greatly appreciate it.

I am also curious about the demise of Hazeltine Research.
All I have read is that the company went under because of the extremely high costs of damages resulting from legal actions against them.

What was all this about?
