CPR Torch

In the close-but-no-cigar department we have the LED torch that gives you basic CPR instructions at the touch of a button. Not bad, but if you have enough forethought to carry one of these around, then surely you'd have enough to take a decent first aid class.

Now if they put this function into something the average person carries around all the time, like a cell phone or butane-powered soldering iron, then you might have something.
