His manager called Bob Brockmeyer , who promptly told him it could not happen ,When told by the manager that he was watching it happen on the TV screen as they talked ,he had no explanation.
The problem was eventually traced to a "dirty" fiber optic connector at the tree .
In talking to a plant operations engineer whos company uses extensive fiber optics and infrared on its machines , he was amazed that they would use fiber optic in that application.
Then he told me about all the issues that can arise using infrared sensors in that environment .

Very interesting. I wonder what the alternative is? Jim
