Patent ID: 8599010

Claim:
A firefighter tracking system used in conjunction with a fire truck to track firefighters at the scene of a fire, the system comprising: a plurality of portable wireless transceiver tags each carried by a respective firefighter; a registration pushbutton located on each of the plurality of portable wireless transceiver tags, the respective firefighter activates the registration pushbutton each time the respective firefighter arrives at the scene of the fire and the firefighter tracking system adds the respective firefighter to a roll of firefighters operating at the scene of the fire; a deregistration pushbutton located on each of the plurality of portable wireless transceiver tags, the respective firefighter activates the deregistration pushbutton each time the respective firefighter leaves the scene of the fire and the firefighter tracking system removes the respective firefighter from the roll of firefighters operating at the scene of the fire; an accelerometer within each of the plurality of portable wireless transceiver tags; a motion processor within each of the plurality of portable wireless transceiver tags coupled to the accelerometer, the motion processor processes information from the accelerometer, detects an immobilized state of the respective firefighter and wirelessly transmits information including a notification of the detected immobilized state; a gateway carried by the fire truck that receives the transmitted information from each of the plurality of portable wireless transceivers; and a status processor coupled to the gateway within the fire truck programmed to determine and display a status of at least some of the firefighters on the roll of firefighters operating at the location of the fire via the received information including at least the immobilized state of the at least some of the firefighters, wherein each of the plurality of portable wireless transceiver tags is completely autonomous and doesn't need any intervention from the respective firefighter in order to perform its functions after the respective firefighter enters the scene of the fire, wherein each of the plurality of wireless transceiver tags further comprise a first motion timer and an audible annunciator, the first motion timer is activated by the motion processor upon detecting the immobilized state, the audible annunciator is activated at the end of a first predetermined time period measured by the first motion timer and wherein each of the plurality of wireless transceiver tags further comprise a second motion timer, the second motion timer is activated by the motion processor at the end of the first predetermined time period, the motion processor transmits notification of the immobilized state to the gateway at the end of a second predetermined time period measured by the second motion timer.
