when was the hans device invented
I also thought of other ideas with straps, and so on, and didnât pursue those because I didnât think they would be as effective as the HANS.â. âI came up with the basic concept for the HANS Device in the middle 80s and filed my first patent application in 1985. I am a professor at Michigan State University and I was doing this on the side. I didnât have any real funding behind me at all.
