ABSTRACT:
A method for accounting for individuals in an emergency at industrial facilities utilizing Ultra-Wideband (UWB) transmitters associated with individuals or objects and UWB monitoring stations. Identification information received from the UWB transmitters by UWB monitoring stations are communicated along with time of arrival information to a computer which calculates the location of the UWB transmitter. The system can be used despite severe multi-path effects and can provide location information in 3 dimensions. The system can optionally include proximity-based RF equipment for access control or otherwise for identification in specific locations. Information from the proximity-based RF equipment is also sent to the computer which also receives information from the UWB monitoring stations.
