It would be fun to explore and investigate. I do believe someone has already done this in the field of burglar alarms. In fact I seem to remember this being done about 15 years ago but not with a computer. They only used a black and white camera and detected any change in a defined area of the picture and then sounded an alarm. I/we/lots of folks have been thinking about a LDS (life Detection System) for a long time, mostly as it would apply to a Cryonics patient that is alone and bed ridden There are lots of ideas and situations and a lot of equipment that could do the job. There are not so many people that need this protection. So I could see no way to make it pay and it would have to be done for the love of doing it. Charles Platt and I have been talking and he has suggested, "Keep it simple" and with that in mind I have started with a common hardware store Motion Activated light Control. I plan to modify it to increase the time out to 30 minutes. It has a range about 12 feet wide to 15 feet deep. This would be enough to cover a bed.. The detector cost about $9.00. I will couple this to a Sensaphone burglar alarm device that I have in my junk box. I think the original cost was about $30.00. When the Sensaphone is triggered by the motion detector it will call a phone number and deliver a message. I also plan on a sensitive floor mat switch that would go under the mattress and activate the system only when someone was in the bead. As you can tell this is a very simple system. I am playing with it in my spare time and so it has a low priority. Unless I can get other feed back it will stay as a low priority. Joe, Please let me know if you have any other inputs to an LDS project. Billy H. Seidel 310-836-1231 Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=7518
