Can I fit the system to my helmet myself? To me it feels like it is most critical
where the mounts go on the helmet so there is no rotation of the head/neck in a crash, for instance it they are mounted too far up the head would be tilted up/backwards. Ouch...
Is the system a use-throwaway or is it reusable? I'm thinking that there would be quite a lot of heat buildup when the system absorbs that amount of energy.
What kind of fluids are used? Flammable/high pressure/toxic?
"The video is on analog tape (NTSC format). We may eventually convert it to digital and post with other videos."
Hmm, Never The Same Color? (NTSC) It will play in my VCR if it hadn't broken down a couple of years ago.

Please notify us if it's posted in digital format.
I'm mostly interested to see how the head moves (rotates) during a crash and that I think can be seen even in a very small impact.
"Second, some drivers who have never used the Isaac system express a concern about having to get out quickly in an emergency. Every customer we have will tell you that this is nonsense--you can pop the helmet pins in less than a second. In the video, you can see the driver release the Isaac while he is in the car, upside down."
The problem as I see it is that you place more responsibility in the hands of the marshals if the driver pass out, maybe thats something that they do not like and therefore won't let me use it...
"Tilt your head over as far as you can. Guess what? You're not dead."
Seem to me that you got a good design using shock absorbers instead of springs, excellent concept.
