First- I said Smith's tied up with 1St Detect was to develop ETD. Second- I am talking about NON-CONTACT ETD. Hate to tell you but Smith's does NOT have non-contact ETD approved by TSA nor CRADA'd with TSA. ISC DOES! Third- I said Smith's AQ was an IP driven event- so they now have TOMO and X-RAY EDS. Fourth- I never said ISC would get 100% of the 800M TAM, I said 66% of that number. I used 66% to calculate a possible EV for ISC. Finally, either you have to read what I write or I have to IGGY you...
