Abstract
A personal security system locates emergency transmissions and tracks changes in location between successive transmissions. The transmissions are repeated automatically over a predetermined time interval exceeding five minutes. A plurality of fixed receivers are provided in predetermined positions in a protected region for detecting the emergency transmissions and a central monitoring station locates the transmissions from information provided by the detecting receivers. The monitoring station tracks successive transmissions and displays multiple locations as icons on a monitor. The icons vary in size based on relative transmission time and are stacked so any overlapping icons representing more recent transmissions are on top.
