I think this might be the gyroscopic one.  Science or Scientific
American had a good article on it.  Simple and cheap.  The only thing
required was some electricity to spin the gyro and the IR sensors would
do the rest.  (This is all of recollection on my part so pardon me if
Alzhimers is setting in at the ripe old age of 25... :-) )

Haltek is selling them as well.  I think they had an add on the back of
Nuts and Volts.  (Anyone got a lifetime subscription yet outside of CA?)
