Locator system
First Claim
1. A fob for use with a cellular network and a global positioning system, said fob comprising:
- a cellular network transceiver for establishing a telecommunications link with the cellular network;
a global positioning system receiver for generating an output of GPS location coordinates of said global positioning system;
an independent radio frequency tracking beacon transmitter actuable for transmitting ID/data radio frequency signals, said independent radio frequency tracking beacon transmitter being independent from said cellular network transceiver, and said ID/data radio frequency signals having an identification code for identifying said independent radio frequency tracking beacon transmitter; and
a protocol processor for electrically controlling said global positioning system, receiver, said cellular network transceiver and said independent radio frequency tracking beacon transmitter, and said protocol processor sending control signals to said independent radio frequency tracking beacon transmitter to cause said independent radio frequency tracking beacon transmitter to transmit ID/data radio frequency signals for detection by one or more tracking unit(s).

Abstract
A locator system for locating a person, animal or mobile object for use with a cellular network, the locator system including a fob containing a GSM transceiver for communication with the cellular network, a GPS unit for indicating the location of a person, animal or object being searched for, a baseband processor for controlling electronic modules in the fob and an RF beacon for transmitting strong ID signals in pulse form for indicating the direction and location of the fob. The system can operate with a call center to which communications are made by a guardian seeking assistance in finding the lost person, animal or object, which in turn communicates with the cellular network to send signals to activate the fob and which receive signals from the fob. Mobile or handheld tracking units pick up GPS and RF beacon signals to find the fob. The locator system can be used in combination with a residential locating system.
