To accommodate emergencies involving the solitary aged, we have developed a collapse-sensing phone with a GPS receiving chipset and a CDMA sending chipset that reports the location of the individual to a local control center. A GIS has been developed to display the position of the caller on the map of a control system that enables administrative officers to rescue the aged people.
