I saw a really nice one a few years ago, it used a Ricoh auto-focus lens (just like an SLR), it was used at a coal fired power station for maintenance purposes - they regularly recorded measurements at various places, looking for changes signifying a possible problem. This one would read a humans body temperature at 20-30 feet, and went up to seriously high temperatures - as they obviously need in a power station!. I suspect it was SERIOUS!! money!. -- Nigel. /--------------------------------------------------------------\ | Nigel Goodwin | Internet : nigelg@lpilsley.co.uk | | Lower Pilsley | Web Page : http://www.lpilsley.co.uk | | Chesterfield | Official site for Shin Ki and New Spirit | | England | Ju Jitsu | \--------------------------------------------------------------/ -- http://www.piclist.com hint: The PICList is archived three different ways.
