It may be more than that, Look at the debate about whether it is using Ramen technique. I see a clue in the old PR's
"Company will exhibit its proprietary ValiMed G4 multi-component medication and narcotic detection system"
First of all "its proprietary". It is?
Second, "multi-component"? They have droped this title in later PR's So what did they do take something out? If it uses ASD stuff, then why not press to get your suit winnings?
