To increase the chances of saving victims of cardiac arrest, this winter the San Ramon Valley, Calif., Fire Protection District launched a feature on its free iPhone app called Fire Department that notifies citizens in the area when someone is suffering from an emergency requiring CPR.

Basically, trained people sign up, and 911 *pings* them if their GPS reports them as being adjacent to an emergency, to get trained people on-site faster.
