This all seems very complicated to me.  I'm not much of a hardware person,
but here's an idea I hope is worth considering:  One can buy a wristwatch
today that measures pulse (usually used for aerobic exercise).  What is
missing is:  1) a signal that is activated when the pulse measured is zero
(or when the little "heartbeat" symbol hasn't appeared on the LCD display
for a while); 2) a sensor (pressure? light?) that can tell whether it's on
a wrist so it doesn't give the signal when it's not.

If the phone part could be altered to detect the signal, we'd be done.  And
could the signal activation part (and maybe even the "activate phone call"
part) be done by tweaking one of those "I've fallen and I can't get up"

Such a device (or set of devices) could probably be marketed and sold
for good money, so I hope that someone out there can and does do it.
