I see four different devices. One is Thermo Electron, another is GE. Does anyone recognise the other two. Elsewhere I saw that Smiths was one of the others. I can't ID it as one of the other two depicted in the lower photo.
In the picture with four devices, the far back one is the same Egis Defender as in the other picutre, then coming forward the GE VaporTraer and the last two are both EVD-3000's from Control Screening (formerly IDS, formerly Scintrex).
Another article listed (3) manufacturers. IMX was not among them. I don't remember if the article said they were the ONLY 3. It's disappointing for longs that they were not mentioned by name in that article.
You think you would remeber the article if you recall what it said. lol , if your trying to push the stock down that isn'e evn credible. there are three different devices from different companies. I can bet IMX's is one of them.
