Abstract

A security system uses tags that are able to transmit RF signals to readers located around a college campus. The tags may transmit signals periodically or in the event of an emergency. Certain locations use LF readers with exciters that trigger a signal from the tag. The security system may provide quick identification of individuals in danger.

Claims

1. A security system comprising:

a tag, wherein the tag emits signals;

a first RF reader for detecting emitted signals;

an LF reader for detecting emitted signals;

a central database adapted to receive transmissions from the RF signal reader and the LF signal reader, wherein said central database uses the transmissions to triangulate a location of the tag in an area; and

wherein the LF reader further comprises an LF exciter for causing the tag to emit signals.

2. The system of claim 1, wherein the first RF reader is a short range RF reader with a spherical range of up to 300 feet in diameter.

3. The system of claim 1, wherein the first RF reader is a long range RF reader with a spherical range of up to 800 feet in diameter.

4. The system of claim 1, wherein the first RF reader is a Yagi long range RF Reader with a directional range of up to 2000 feet.

5. The system of claim 1, wherein the RF reader operates a frequency range between 300 MHz and 933 MHz and the LF operates in a frequency range between 30 kHz and 300 kHz.

6. The system of claim 1, wherein the first RF reader is a short range RF reader with a spherical range of up to 300 feet in diameter;

and further comprising a second RF reader with a spherical range of up to 800 feet in diameter and a third RF reader with a directional range of up to 2000 feet.

7. The system of claim 1, further comprising an infrared reader.

8. The system of claim 1, further comprising a display for displaying the location of the tag in the area, wherein said display comprises a vector floor plan of said area.

9. The system of claim 1, wherein the tag further comprises a motion detector.

10. The system of claim 1, wherein the central database further communicates with a cell phone or PDA.

11. A method for providing security for an area, comprising:

providing a tag, wherein the tag emits signals at a first time interval and a second time interval, wherein the first time interval is shorter than the second time interval;

providing RF readers for detecting emitted RF signals in an area;

providing LF readers for detecting emitted LF signals in the area;

detecting a signal from the tag at one of the RF readers and the LF readers;

transmitting the signal to a central database, wherein said central database uses the transmissions to triangulate a location of the tag in an area.

12. The method of claim 11, wherein the LF reader further comprises an LF exciter for causing the tag to emit signals.

13. The method of claim 12, wherein the LF reader causes the tag to emit signals at a third time interval, wherein the third time interval is shorter than the first time interval.

14. The method of claim 11, wherein the central database further communicates with a cell phone or PDA.

15. The method of claim 11, wherein the first time interval is selected from a range between 1 and 20 seconds and the second time interval is selected from a range greater than 20 seconds.

16. The method of claim 11, wherein at least one of the RF readers is a short range RF reader with a spherical range of up to 300 feet in diameter.

17. The method of claim 11, wherein at least one of the RF readers is a long range RF reader with a spherical range of up to 800 feet in diameter.

18. The method of claim 11, wherein at least one of the RF readers is a Yagi long range RF Reader with a directional range of up to 2000 feet.

19. The method of claim 11, comprising operating the RF readers at a frequency range between 433 MHz and 933 MHz and operating the LF readers in a frequency range between 30 kHz and 300 kHz.

20. The method of claim 11, further comprising displaying the location of the tag in the area on a display having a vector floor plan of the area
