Ran across this Patent the other day and thought I'd post it.   Heard about it for years.   This is Dan Kincheloe's vision of the future.   Well, his future, not mine, I hope!   The trouble with shit like this is it ends up being mandatory...   No matter what the inventor tells himself.   "I will save lives"  or more likely " I'll be rich!!!"   No matter the motivation, when something like this gets to that certain place.   Some big corporation or do good organization sinks their teeth into it, you and I have to live with it...   Maybe I should work on peel and stick patches?
