1. A mobile information device, comprising:
- a sensor for detecting a stimulus from an external environment and for outputting a signal responsive to an intensity of the stimulus;
a position-determination control unit for obtaining position information;
a notification destination table for storing information of an emergency notification destination; and
a notification control unit for monitoring the signal output from the sensor, for transmitting a prescribed emergency code to a reference station when the signal attains a certain level or above, for obtaining current position information by activating the position-determination control unit, and for transmitting the obtained position information to the emergency notification destination stored in the notification destination table.

Abstract
When the intensity of stimulus to a mobile information device from an external environment has attained a certain level or above, the mobile information device transmits an emergency code to a reference station. The reference station transmits an emergency response code to the mobile information device so as to forcibly activate the location-determination control unit. The current position information on the mobile information device obtained by the location-determination control unit is transmitted to the emergency notification destination.

11. A method of performing an emergency notification, wherein:
-
a mobile information device detects a stimulus from an external environment, transmits a prescribed emergency code to a reference station when an intensity of the stimulus has attained a certain level or above, and forcibly activates a position-determination control unit of the mobile information device by receiving, from the reference station, an emergency response code indicating reception of the emergency code; the position-determination control unit obtains current position information of the mobile information device on the basis of arrival times of radio waves to a plurality of reference stations; and the mobile information device transmits the obtained position information to an emergency notification destination.
