Abstract

A signaling system is provided for rendering an alarm for an individual in distress combined with a locating and tracking system to thus alert and direct appropriate personnel to the needs of the individual in distress and to monitor the location of that individual. The system comprises a portable signaling unit, a remote alarm switch device, a central dispatch station, and makes use of a wireless communication system. The portable signaling unit and the remote alarm switch may be adapted to be worn at different locations on the person'"'"'s body. The remote alarm switch way be concealed in the form of a wristband or in the form of any other object such as a broach, pendant, or keychain.

Claims

1. A personal security and tracking system comprising:

a portable signaling unit including a GPS receiver for receiving a GPS signal including position information for the portable signaling unit, and a cellular telephone antenna adapted to transmit a cellular digital packet data (CDPD) signal that includes the position information;

a central dispatch station located remote from the portable signaling unit and adapted to transmit a control signal that includes the position information, the central dispatch station adapted to automatically determine a location of the portable signaling unit based at least in part on the position information received in the CDPD signal; and

a cellular telephone system adapted to receive the CDPD signal from the portable signal unit and re-transmit the CDPD signal to the central dispatch station, and to receive the control signal from the central dispatch station and re-transmit the control signal to the portable signaling unit, thereby providing two-way digital communication between the portable signaling unit and the central dispatch station.
