How Can I Build a Portable "Dead-Man's" Switch?

An anonymous reader asks: "I'm a widower caring for my very disabled child. I have family who check in on me often, but not reliably, and not every day. How can I rig up a 'dead-man's switch' that will alert family or emergency services should something happen to me, so that my child can be cared for? Her medical needs are significant enough that being alone for even an hour could be fatal for her. We do occasionally get out of the house, so a GPS type cellphone and a heart-rate monitor watch would seem to be the ticket, but how to link the two and get the desired dialing behaviour?"

      If I understand the gp post correctly, the monitor talks to a server, not to the emergency services directly. So all the server needs to do is behave like every well behaved monitoring application should by using a set of alarm thresholds:
      • Alert only after X positives or Y minutes of positive alarm
      • Alert only after the server has failed to poll the client for X consequtive times over Y minutes
      • Turn alert off after X negatives or Y minutes of negative
      • Clear positive counters after X negatives or Y minutes of negative

      And so on. Trivial, but unfortunately missing/buggy in most purpose built monitoring applications even from "big" vendors. In fact it is so common that if I see an embedded monitoring with its own alerting, it is my first thought to kill it and replace with an interface to a proper monitoring system that can handle thresholds and time constraints.

    Vigilance control, also called an alerter, is similar to a dead man's switch, the difference being that a vigilance control system requires that the operator press a button at specified regular intervals. If the operator fails to operate the vigilance control, a warning sounds, and should the driver still not operate the vigilance control the machinery will stop.

    I have one of these motorola pagers that my company gave me to carry around. It may only be available in Canada, but I'm sure you can find something similar in your area.

    At any rate, you can send a page to it with an email, and then you have the option to reply to the email with a canned response like "OK" or "Will call back soon", etc. I was thinking that you could write a script on a server that would kick off an email to your pager every 30 minutes and if it didn't see a response within 15 minutes, activate some kind of emergency routine like contacting a relative. The timing could be varied to your needs.

    It would be easier if you had something that hung around your neck, or a wristwatch that beeped every 15 minutes and required you to push a button to silence the alarm. Not silencing the alarm would somehow trigger your emergency routine. Using a windows mobile device or a blackberry (the API is available for free) you could write a program for one of these devices to do this task and send an email if you failed to respond.

    Of course, this only works during waking hours. I don't know if you hire someone to watch your child during the night while you're asleep or not.

While I must applaud your desire to not institutionalize this person, sometimes that really is the best situation if you want them to survive beyond anything that might befall yourself. It's a tragic choice to have to make, but what you're really looking at is this: 1. should I continue caring for this person and accept that they might die if something happens to me, or 2. should I institutionalize them and know that they will have continuous care regardless of what happens to me, but that it will be at times impersonal. Personally, I would probably choose the latter if the other person's life was important to me, but then choose to spend as much time as feasible with them at the institution.

  39. Asterisk can do awake time monitorring by Pitawg · · Score: 4, Interesting

    I make heavy personal use of Asterisk PBX software. It allows my blacklisting unwanted calls. It also allows my own system of "follow-me" call forwarding to pass calls to my cell if the home extensions fail to answer.

    Scheduling a call with the cron daemon is pretty easy. A kind of wake up service is also fairly easy to setup. With a cordless phone for home use, this could call said extension at various times of the day. When you answer the call, you would have to press a number or something to confirm that you are fine. Failing to press the number, it could make second attempts in case there was just fumbling, like a followup call within a minute or two. Failing more than once, it could email people, send calls to people, play a recorded message for each call appropriate for the target of the "notification". With the use of a cell phone, it could even check on you when away from home since it could work like any automated phone call/customer service line. Besides having a phone ring to wake you up in the middle of the night, hampering your sleep, I do not know how much help it would be in the night time hours. The cordless phones out now could cover most of people's small yards as well. It can also be easy to "911" yourself carrying it around with you, and with a little more effort, when you call 911, it could make other calls automatcally for you. Think 911 with a custom menu for types of emergencies with phone and email notifications to work with.

    The mutltiple notice to people for multiple types of needs using multiple methods of communication could be of some help. Cell phone calls to my house, being identified as my cell phone via "caller id", I get prompted with a menu to allow me to cause things to happen, when any other call would ring the phones in the house. A cell phone speed dial could be setup to call home and cause functions to occur using said "menus" which are limited by what you can get a pc to execute. (email, phone call outbound recordings, serial cable control for some devices, IR controls of something near the computer with a TV universal remote function....)

    Some of these ideas could enable automated response testing, and easy one button emergency notification. The GPS portion could be handled by recorded messages from cell phone orginating "emergency button" to mention the cell phone number/carrier to emergency contacts for use in tracking. Not so automated in that respect, but seems to be a workable solution.

Then we found out we liked it even more if we did it often. Then we found out that we really really liked it when everyone involved chose to do it and was having fun. This gives us an ability to meta-evolve; by preferentially choosing partners that show traits that we find desirable, and one may assume in some percent of cases these are normalized to some societal mean, we have given ourselves the ability to self-direct evolution for future generations, merely by creating a society that values some individuals and doesn't others.

    I think we're going to see that now that we're fully conscious, evolution will continue to be less and less about the physical body, at a pace roughly equivalent with increases in medical technology, and will be more and more about creating organisms that function excellently as part of a large diverse society - and evolution starts and ends at sexual desire on this score.
