Firefighters have a simple process for donning there gear so that they can get on the truck and to the fire quickly. Study this process more closely to see how they use possibly velcro over buckles to make the donning process faster.
Yes, I'm interested in developing this idea further. I've considered interviewing and possibly observing people like race car drivers and firemen to help further develop the idea. I have also seen the link and that is a great idea.
Nick, this is a great idea because now you have GPS location, probably a unique ID (so you can track to a certain patient) and their condition (improving, temperature high, need help, etc.). You could give one to each patient.
