X-Message-Number: 5582 Date: Sat, 13 Jan 1996 23:14:58 -0500 (EST) From: Charles Platt <> Subject: Emergency alerts Mike is of course correct: the pulse-sensing alarm system I outlined would entail significant R&D costs, whereas the motion-detection system he suggests would be much cheaper to create: the quick-and-dirty approach. At this point I have reached the limit of my knowledge about hardware. I believe (but may be wrong) there are now programmable chips that could be used as a shortcut for the kind of thing I have in mind; but someone such as Keith Lofstrom (do you still read CryoNet, Keith? Are you there?) would be the right person to address this question. --CP Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=5582
