Abstract

An automated accountability system is achieved by a unique combination of at least one stationary, passive-infrared activated low-power wireless RF locator-transponder device, at least one personal issued “pager-like” RF transceiver device and a stationary transceiver contained in a stand-alone master command base monitor or a stationary transceiver connected to a personal computer with monitoring software. These three primary components form an automated accountability system for tracking and locating personnel. The locator-transponder device is capable of detecting the presence of a person or object. The person carries the adjustable level low power radio frequency transceiver device and as the transceiver passes the locator-transponder, a signal with at least identification, status and location information of person. The information is provided automatically without intervention to the automatic accountability system.
