I don't think is a patent ( maybe it was ). I have a relatively new one, german made, that works exactly like that: two knobs, one for setting the power and one for setting the time.

Both are on the fly adjustable, both power and time. I find it really good design.

That's good to hear. I miss my on-the-fly adjustable one. When it broke down, I looked but could not find a small one (<=.9fcu), so I went with a Pana that had a dial since I rather dislike the touchpad ones.
