Interesting safety device for shop power tools, especially saws:

http://www.sawstop.com/home.htm

"The SawStop system works by recognizing the difference in the 
electrical properties of wood and a user. The system induces a 
high-frequency electrical signal on the blade of a table saw and 
monitors this signal for changes caused by contact between the blade and 
a user's body."

I know a few guys who'd probably still have ten digits if they'd have 
had something like this...
