That's not to say the SS owners won't be also; altho I'd worry somewhat
with them with regards to that long-term reliability of the electronics
without, at least, key component replacements/updates--the double-edged
sword of electronics.

Now that there's (finally!) been an apparent retraction on the tablesaw
question, the above query/concern--

Is there a test mode I presume for the electronics or a power-on test
that the brake detector circuitry is operational?

What sort of warranty and maintenance schedule is given for the
electronics outside of the saw mechanicals, any?

Wonder what sort of failure rate there's been in the field; they've been
out approach 10-yr now or so?

On the subject in the other subthread regarding
"patent-infringement-avoidance" engineering, I first heard of the SS
patent and brouhaha with the established manufacturers while still
employed in the new product development section (before dad passed away
that was the impetus for the move back to the family farm). Being as
such non-contacting measurements were our forte albeit in other fields
of application and that was a moderately avid woodworker, it intrigued
me personally about whether could manage to work around their patents if
it were to come to it. I did have a couple of ideas, one of which did
make a lab prototype of the detection circuitry that did function that I
think could be developed to do the job. It's not quite up to the
"neatness" factor of the SS technology, but convinced me the other
manufacturers could, if they were to choose to do so, build a similar
capability and circumvent the SS patent. I expect they all have
something similar in their development labs and are simply waiting to
see what, if anything, actually comes out of CPSC rulings first.
