Abstract

A tracking system for locating individuals and equipment as well as providing directions within a building includes a plurality of transmitters that are positioned and associated with specific locations within the building. The location of the transmitters is stored in a database of a controller. An individual is provided with a receiver that detects signals sent by the transmitters. Each receiver has an identification code associated with the individual that is stored within the controller'"'"'s database. The receiver forwards detected information on to the controller and based upon the information, the controller displays an icon associated with the receiver on a grid of the building that shows the location of the individual within the building.

Claims

1. A tracking system, comprising:

a building having a plurality of rooms;

a plurality of transmitters positioned throughout the building and associated with a particular location within the building;

a receiver used by an individual and having an input device, a display, and a speaker; and

a controller having software that accesses a stored directional path based upon a present location and input desired location wherein the controller transmits commands to the receiver based on a signal detected by the receiver that the controller determines is strongest.

2. The system of claim 1 wherein the command is displayed and accompanied by an audio command.

3. The system of claim 2 wherein the controller transmits additional commands based upon a closest detected signal from one of the transmitters.

4. The system of claim 1 wherein the controller activates an alarm when a signal from one of the transmitters detects that the individual has entered an unauthorized area.

5. A tracking system, comprising:

a building having a plurality of rooms;

a plurality of transmitters positioned throughout the building and associated with a particular location within the building;

a receiver used by an individual and having an input device, a display, and a speaker; and

a controller having software that accesses a stored directional path based upon a present location and input desired location wherein a computer compares detected signals from the transmitters with transmitters on the directional path and displays on the computer a command when the individual reaches a transmitter associated with the command.

6. The system of claim 5 wherein the directional path is comprised of multiple commands where only the first command is displayed.

7. The system of claim 5 wherein the computer accesses a new directional path and advises the individual they are going the wrong way when the individual moves away from instead of toward a transmitter associated with a subsequent command.
