From article <743@optilink.UUCP>, by brad@optilink.UUCP (Brad Yearwood): > Which brings me to a question. There is a second LED, presumably infrared > emitting, in the Mouse System mouse, to the left of the red LED. If you > look carefully (particularly if you cover the red LED), the infrared LED > appears to have a pale bluish-gray glow. The Mouse System mouse is an optical mouse. Light goes out, some light goes back in. The second "LED" isn't a led, its a photosensor. I would guess. -- Dave ---------------------------------------------------------- Dave Bakin (408) 496-3600 c/o Rational; 3320 Scott Blvd.; Santa Clara, CA 95054-3197 Internet: dsb@rational.com Uucp: ...!uunet!igor!dsb
