A motion detecting pager like device is worn by a sick or elderly person. If a certain time period passes with no motion detected by the device, or no signal from the device, it will call friends, family or emergency services.

It is actually a stillness sensor - the alarm activates when no motion is detected. [ed, Aug 21 2008]

Same idea, I think. [phoenix, Aug 22 2008]

I personally used a similar device to ensure an infant in my laboratory kept breathing throughout the night over several months. Rather than wearing the device, it is configured under the platform where the subject sleeps. Unfortunately, the device also transmits an insecure audio feed from the subject's quarters; hacks are needed to work around this.

Nothing weird or abnormal, we're sure. Why, where do you keep your infants ?

I always kept my infants in the ice box where they wouldn’t spoil… now that they are older, I can't keep them out of the ice box...

When i first saw this, i thought it'd be something along the lines of a motion lamp that turned OFF when motion was detected.

Bun for this use for it though.
