Abstract:
A personal alarm monitor system provides for the recording of a record of locations of a person as the person travels through a designated premises having a series of designated areas interconnected by portals or gateways, such as doorways. The person carries a receiver capable of receiving broadcasts from a series of preferably low-power transmitters specifically located throughout the premises. Pairs of transmitters are located at each gateway, one transmitter being placed in each of the adjacent designated areas to broadcast a signal primarily into the designated area about the gateway. Additional unpaired transmitters may be located at additional locations in the designated areas. Each transmitter is assigned and broadcasts a unique code corresponding to its location and status as either a gateway or non-gateway tag. A portable receiver, carried by a person whose location is to be monitored, receives the unique code broadcasts from the transmitters and processes the code data to validate the position it represents. When validated, the code is stored by the receiver. A list of the validated codes can be downloaded or transmitted to a remote location for tracking purposes.
