How does the SawStop prevent *kickback* ?? The whole point of the device is to
prevent *amputations*.

Besides its namesake feature, the whole saw is designed to increase
safety compared to more traditional saws. Probably the main
improvement is the riving knife (splitter) that rises and falls with
the blade, allowing it to say in place for most any cut. I'm not
enthused by the company's politics and think the sawstop brake thing is
overhyped and overdesigned, but IMHO the riving knife that falls with
the blade is a desireable feature for both safety and performance.

I'm no patent lawyer, and I don't know exactly what the sawstop
patents cover, but I dont see how anyone could patent the broad idea
of a safety device that stops a sawblade or any other type of moving
machinery. There's just too much prior art. I suppose there is some
merit in the sensor design part of the patent, but even so, I don't
see that as being something unique, it could be done another way.

Did you ever try to select a floor in an elevator with the touch-style
buttons by tapping them with a pencil?
