I'm finding it incredibly interesting that two of the four finalists are immigrants to the US, and the other two are minorities.
I find it interesting whenever I see Bush, he's behind a dis-proportionate audience of mixed-race, whether live, or one of those back-drops with people-pictures and sound-bites.
I don't see how the force of a 40 mph impact will not transfer to that seat before it starts spinning.
The trick is to control the *rate* energy is transferred to the seat. Springs and dampers can do this - tuned by electrically acceleration sensors.
Does the energy of the force somehow get absorbed in such a way that it automatically translates to "spin," or does it translate to "blunt/spin?"
I honestly think that car seat is doable, and I know there are ways to measure stress during impacts.
I'm going to have to call my dad about this. He worked in the collision business for over 50 years and witnessed the results of every kind of car crash imaginable, including those that have killed infants, children, adults, and pets.
There are many devices, "accelerometers", as simple as microphones or much more complex, to sense inertial forces.
My idea is to use a radar sensor to determine the trajectory of the occupant along with inertial sensors in the seat, then use an airbag with an array of explosive cells, initiated spacially and sequentially, to create a tailored profile tuned to the deceleration vector of the vehicle, mass and area of the occupant.
All I need is a few million. But no doubt you'll see them soon. Its damn hard to think of anything really original.
