Eltec Instrment, Inc. (1-800-874-7780) makes pyroelectric detectors
and I agree they are really cool!  I have been researching them for use
in home robotics to differeniate humans from other inanimate objects.
I've been writing a research paper for one of my classes that I will
probably put on my WEB page in a couple weeks if anyone is interested.
