…so all that time JJ talked about 'acoustic' sensors he was barking up the wrong tree? [I suspected that part- but I did think the acoustic signature info was part of our patent on weld pool monitoring too? Or is that from the patent Mark and Vivek worked on that's owned by the gov't still? Legitimate question- I really don't know…. anybody? If EOS is using Fourier Transforms to bypass patent infringement I am not happy about it. (That's too simple a fix for us not to be doing it, if it really is based on Mark and Vivek's past work).
