Sigma Labs Inc (SASI)

Thanks JPI, for the additional info. It is always preferable to see Sigma's name directly in these articles, versus hidden within a team they are collaborating with. Also, after a quick look at the PDF I was concerned that Concurrent Technologies Corporation had somehow replaced us. But, after a closer look that is not an issue:

The team led by Concurrent Technologies Corporation (CTC)
focused on maturing flaw seeding techniques within test
specimens and establishing accurate and reliable NDE size
limitations for detecting the seeded flaws.
