class project ... plz help! (long)

thanks everyone, i hadn't thought of the seat occupancy thing yet. i was thinking of something kind of like it though.... a child seat that had the sensors and stuff built into it. then you could actually monitor the heart rate and body temp etc. the only problem is if you have kids who don't use a child seat or if you have pets. another idea i came up with is using thermochromic (automatically darkens when exposed to heat) smart glass to reduce the interior temp.

and yes, i just found out about GM's project thanks to Tonitrus' post. just my luck... one good idea my whole life and someone else already thought of it, lol. back to the drawing board!
