Abstract:
1. A monitoring system for monitoring an alert indicative of an emergency situation comprising: at least one wireless transmitter transmitting a wireless signal indicating an emergency situation exists, said wireless signal further including information related to an individual to whom the wireless transmitter is assigned; a plurality of transceivers located throughout a facility including a first transceiver that receives the wireless signal and transmits an alert signal to a security alert station indicating the identity of the transceiver that received the wireless signal and identifying the individual to whom the wireless transceiver is assigned; wherein when said at least one wireless transmitter is moved away from the vicinity of said first transceiver and toward the vicinity of a second transceiver, the second transceiver transmits an alert signal to the security alert station indicating the identity of the second transceiver and identifying the individual to whom the wireless transmitter is assigned; and wherein when both the first and second transceivers transmit alert signals, the system performs a signal strength comparison to determine which transceiver received a stronger wireless signal such that the monitoring system tracks the movement of the at least one wireless transmitter as it moves throughout the facility.
