That’s really interesting! I love my SawStop cabinet saw, but it is good to see some other manufacturers entering the field. Competition results in innovation and reduced prices for consumers. The SawStop system that destroys the brake and the blade is less than optimal, but good enough for me when housed in an otherwise high quality cabinet saw.

I am curious to see how the Bosch system works. The SawStop system uses the energy inherent in the rotating blade to drive the blade below the table while the aluminum brake block halts the rotation. Bosch seems to be using air bag technology to generate the energy that drives the blade down. I am eager to see just how this works to provide a stable depth setting for the saw blade in normal use and an easily replaceable safety component. Could be better than the SawStop method. Or not.

As a retired science guy who spent far too many hours working with the patent attorneys trying to craft the optimal patent applications to carve out our little slice of intellectual property, I wonder what the situation is regarding table saw brakes. I have no clue just where this stands, but at some point the concept of using the capacitive measurement to trigger a brake might have been patentable. Does SawStop have any intellectual property position that could hinder others?

Note: The other replies were posted while I was (slowly) typing. All I can say is don’t underestimate the ability of an expensive legal team to muck up this whole issue. I have no knowledge of the history of the technology behind table saw brakes, but I know from experience that the legal fog can throw a multitude of monkey wrenches in the best laid plans, even when you KNOW you are right.
