Abstract
A voice-activated personal alarm includes a satellite global positioning receiver, a specific danger sensor, a voice activation circuit, and a radio transmitter. In a specific embodiment, the satellite global positioning receiver relies upon the U.S. Global Positioning System ('GPS'). In another specific embodiment, the radio transmitter is provided by a wireless telephone using an existing wireless communications network and therefore also provides a two-way voice communication channel. In a specific embodiment of the invention, a distress phrase such as 'HELP!' spoken into a microphone is recognized and activates the radio transmitter to transmit the current global location. In another embodiment, the detection of a specific danger by the danger sensor also activates the transmission of the current global location.
