Pete: Does the SawStop operate by sensing leakage current through the human finger to ground, or does it sense the human body’s capacitance (like those touch sensors that control small table lamps)?
Also, I read their literature, but I didn’t see any mention of false-positive actions. Is there some white-paper that SawStop has which might have some better technical details?

I talked with them during development; their primary problem was that the product wasn’t explicitly covered under the standards for the product they were intending this for. We discussed paths to changing the standard (which takes years, too long) or convincing major customers that the product was acceptable even without the 3rd party approval. It all seemed too long range so they proceeded on their own and were eventually successful. I’ve seen the demo video but don’t have it or know where it might reside; the demo was amazing and convincing. Has there been a search on You-tube yet? Maybe Rich Nute knows where such might be hidden. :>) br, Pete Peter E Perkins, PE Principal Product Safety & Regulatory Affairs Consultant PO Box 23427 Tigard, ORe 97281-3427 503/452-1201 IEEE Life Fellow [email protected]<mailto:[email protected]> Entropy ain’t what it used to be - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
