It couldn't be any sort of electronic proximity sensing, or really
any active
technology, or it would infringe on SawStop's patent. That patent is
pretty
damned air-tight.

Maybe not, but the drive to save money is pretty universal. I imagine
most saw builders are working on the safety issue as we speak. I agree
it's difficult to find a competing technology or we'd have seen it by
now. Doesn't matter, I believe it's just a matter of time.

I can imagine some type of beam of light that recognizes tissue and
disengages the saw when that beam is broken. Something will appear, I
have no doubt.

You know, I'm reading this right now on a laptop with a touchpad. I put
my finger on the touchpad, move it around, and of course the mouse cursor
on the screen reacts normally. I try using a piece of wood in the
touchpad,
a few different types of plastic, and even a piece of metal, and nothing
happens. I wonder if there's something useable there as an alternative
to whatever Gass has patented?



It could be a special glove. and yes we have hashed the horror of the
blade grabbing the glove and pulling you whole body in to the saw
through the zero clearance insert. Although I proved that myth wrong
many years ago by pushing a glove into a saw blade and the saw cut
cleanly through the glove with out mayhem. The glove sences the blade
and sends a signal to stop the saw.

Or simpler still protective micro chain mail gloves that simply cannot
be penetrated by a saw blade.
