ABSTRACT:
In a facility having a plurality of portals and having a number of individuals having access to the portals and where each portal is assigned a unique portal for his or her use, a system is designed which allows each individual to receive a unique voice message from his or her portal that a particular portal is the one assigned when the individual is in the proximity of his or her unique portal. The system comprises a uniquely coded element to be worn by each individual and a plurality of transponders, each transponder affixed on or near a particular portal. Each transponder has a device which emits an IR or RF scanning signal for scanning the coded element worn by a particular individual. Each said transponder has an element to determine when a detected signal has the same unique correspondence to a particular portal. The system also comprises a central computer. When there is correspondence between a detected signal or portal, a signal indicating correspondence is directed to the central portal. When a signal indicating correspondence is directed to the computer, it is used to actuate a corresponding unique audio message which is directed to the corresponding portal for audio transmission by an audio speaker located at or near the transponder of the portal.
