The blade is saved. The blade stops by use of a "proximity sensor".

Interesting technology but I can tell you from personal experience that
stopping in about 1 second is not nearly fast enought to prevent bad
cut.
It uses a "proximity sensor". It's not 1 sec after you touch the
blade. It's one second after you "are too close" to the blade.

You can very easily move several feet in one second. If the proximity
sensor
was set so as to keep you far enough away from the blade that you couldn't
get to it before it stops, you couldn't use the saw. Tablesaw accidents
are
over, the damage is done, in milliseconds.

One more thing, if moving "several feet/sec" into a blade, a SawStop
isn't going to help you either.
