Tracking system and method thereof
First Claim
1. A system comprising:
- a plurality of transmitters configured to broadcast electromagnetic signals, the electromagnetic signals having an identifying characteristic;
a receiver to receive the signals from the plurality of transmitters, the receiver comprising;
a processor;
memory operably associated with the processor;
a program of instructions to be stored in the memory and executed by the processor, the program of instructions including instructions to;
associate particular signals received with particular ones of the plurality of transmitters based on the identifying characteristic of the signal;
determine distances between the plurality of transmitters and the receiver; and
generate a notification when one of the plurality of transmitters is farther from the receiver than a notification distance.

Abstract
A tracking system including multiple remote transmitters and a master receiver is disclosed herein. The tracking system is adaptable for use in tracking children, tracking inventory, and numerous other applications. Each of the remote transmitters transmits an electromagnetic signal having an identifying characteristic. The receiver uses the identifying characteristic of the transmitted signal to associate each received transmission with a particular transmitter. The receiver then determines the distance and direction of each transmitting unit from the master receiver, and displays that information, along with a notification, whenever a particular transmitting unit travels beyond a set notification distance from the master receiver.
