Abstract

Systems and methods are provided for determining the location of an individual (e.g., emergency personnel) within an environment having a plurality of RFID tags located therein. A system includes a wearable RFID reader removeably attached to the individual (e.g., on his/her wrist, or uniform), wherein the wearable RFID reader is configured to activate and receive data from a plurality of RFID tags located (e.g., previously deployed) therein. An access port is positioned external to the environment and is configured to receive the data from the wearable RFID reader. A locationing module is communicatively coupled to the access port and is configured to determine the location of the individual within the site based on the data acquired from the at least one RFID tags.

Claims

1. A method for determining the location of an individual within a site having a plurality of RFID tags located therein, comprising:

providing the individual with a wearable RFID reader;

activating at least one of the plurality of RFID tags via the wearable RFID reader;

receiving, via the wearable RFID reader, data acquired from the at least one RFID tags;

transmitting the data to a wireless access port external to the site; and

determining the location of the individual within the site based on the data acquired from the at least one RFID tags.

2. The method of claim 1, wherein providing the individual with a wearable RFID reader includes providing a wearable RFID reader configured to read active and passive tags.

3. The method of claim 1, wherein receiving data acquired from the at least one RFID tags includes receiving predetermined location information associated with the tags.

4. The method of claim 1, wherein transmitting the data to a wireless access port includes transmitting the data to a vehicle located external to the site.

5. The method of claim 4, wherein determining the location includes determining the location utilizing a locationing module located on the vehicle and in communication with the access ports.

6. The method of claim 1, further including providing a display configured to provide a graphical representation of the location of the individual within the site.

7. The method of claim 1, further including transmitting the data to a central office communicatively coupled to a wireless switch that is communicatively coupled to the access ports.

8. A system for determining the location of an individual within an site having a plurality of RFID tags located therein, comprising:

a wearable RFID reader removeably attached to the individual, the wearable RFID reader configured to activate and receive data from the at least one of the plurality of RFID tags;

an access port external to the site, the access port configured to receive the data from the wearable RFID reader; and

a locationing module communicatively coupled to the access port, the locationing module configured to determine the location of the individual within the site based on the data acquired from the at least one RFID tags.

9. The system of claim 8, wherein the RFID tags are “

near me”

tags that receive power and are activated by the wearable RFID reader.

10. The system of claim 8, wherein the data acquired from the at least one RFID tags includes predetermined location information associated with the tags.

11. The system of claim 8, wherein the wireless access port is located within a vehicle external to the site.

12. The system of claim 11, wherein the vehicle is an emergency vehicle.

13. The system of claim 12, wherein the emergency vehicle is a fire response vehicle or a police vehicle having at least two of the access ports located therein.

14. The system of claim 11, wherein the locationing module is located on the vehicle.

15. The system of claim 8, further including a display configured to provide a graphical representation of the location of the individual within the site.

16. The system of claim 8, further including a central office communicatively coupled to a wireless switch that is communicatively coupled to the access ports.

17. A wearable RFID reader system configured to activate and receive data from a plurality of RFID tags distributed throughout an site and transmit the data to a first access port located on a vehicle external to the site, wherein the data can be associated with the location of the wearable RFID reader within the site.

18. The system of claim 17, wherein the wearable RFID reader is configured to be worn on the individual'"'"'s wrist or placed within a uniform worn by the individual.

19. The system of claim 17, wherein the vehicle is an emergency vehicle having a second access port.

20. The system of claim 18, wherein the vehicle is a fire response vehicle having a cab portion and a ladder portion, wherein the first access port is located adjacent the cap portion, and the second access port is located adjacent the ladder portion.
