Abstract

The invention disclosed relates to the end to end system, the methods and an apparatus for locating cell phones, lone workers, assets, and workers in hazardous environments outdoors and indoors. The end to end system integrates with the current E-911 architecture and also provides a stand alone capability for geo-locating workers and assets. The end to end system also provides caller id and geo-spatial location to the E-911 PSAP in the absence of a cellular signal for a cell phone attempting a 911 call.

Claims

1. A system for implementing an E-911 call comprising:

One or more stationary or mobile radar units, wherein the one or more stationary or mobile radar units comprises a radar transmitter and a radar receiver of one or more radar types, the transmitter and receiver of a radar unit being the same radar type

One or more radar responsive tags, the one or more radar responsive tags comprising one or more radar responsive tag types

Wherein the radar transmitter is configured to transmit a modulated interrogation signal comprising commands and data related to the commands

Wherein the radar responsive tag is configured to receive the modulated interrogation signal and transmit a response to the receiver of the radar unit when the radar responsive tag is commanded to respond by the modulated interrogation signal

Wherein the response includes geospatial location data and radar responsive tag status information

Wherein the radar responsive tag is connected to one or more of a cellular network, the Internet, or a local area network (LAN)

Wherein the radar unit is configured to communicate radar responsive tag geospatial location data and radar responsive tag status information to a central system

Wherein the central system is configured to provide the radar responsive tag geospatial location data and radar responsive tag status information to a public service access point (PSAP) router

Wherein the PSAP router is configured to determine a PSAP, from a list of one or more PSAPs, for responding to an E-911 call made by the radar responsive tag based upon the radar responsive tag geospatial location data and the radar responsive tag status information

Wherein the PSAP router is configured to communicate the radar responsive tag geospatial location data and radar responsive tag status information to the determined PSAP for responding to the E-911 call.

2. The system of claim 1, wherein the radar transmitter and radar receiver are multi-static.

3. The system of claim 1, wherein the radar types comprise one or more of bi-static, continuous wave, Doppler, mono-pulse, pulse Doppler, and synthetic aperture.

4. The system of claim 1, wherein the one or more radar units are configured to locate the radar responsive tag in 3-axis.

5. The system of claim 1, wherein the radar responsive tag is configured to interface with a cellular phone.

6. The system of claim 5, wherein the radar responsive tag is configured to connect to the Internet via the cellular phone.

7. The system of claim 5, wherein the radar responsive tag is configured to connect to the Local Area Network via the cellular phone.

8. The system of claim 1, wherein the central system is geographically distributed.

9. The system of claim 1, wherein the central system comprises a display for displaying the location of the radar responsive tag.

10. The system of claim 1, wherein the central system is connected to the Internet.

11. The system of claim 10, wherein the radar responsive tag is configured to connect to the Internet via the central system.

12. A method for implementing an E-911 call from a radar responsive tag to a public service access point (PSAP) comprising the steps of:

Transmitting from one or more stationary or mobile radar units, a modulated interrogation signal comprising commands and data related to the commands

Wherein the radar unit comprises a transmitter and a receiver of one or more radar types, the transmitter, and receiver of a radar unit being the same radar type

Receiving, at the radar responsive tag, the modulated interrogation signal

Transmitting, from the radar responsive tag, a response to the receiver of the radar unit when the radar responsive tag is commanded to respond by the modulated interrogation signal,

Wherein the response includes geospatial location data and radar responsive tag status information

Wherein the radar responsive tag is connected to one or more of a cellular network, the Internet, or a local area network (LAN)

Communicating, by the radar unit, radar responsive tag geospatial location data and radar responsive lag status information to a central database

Providing, by the central database, the radar responsive tag geospatial location data and radar responsive tag status information to a public service access point (PSAP) router

Determining, by the PSAP router, a PSAP, from a list of one or more PSAPs, for responding to an E-911 call made by the radar responsive tag based upon the radar responsive tag geospatial location data and the radar responsive tag status information

Communicating the radar responsive tag geospatial location data and radar responsive tag status information to the determined PSAP for responding to the E-911 call.

13. The method of claim 12, wherein the radar responsive tag is connected to a cellular phone.

14. The method of claim 12, wherein the one or more stationary or mobile radar units interface with the Internet.

15. The method of claim 13, wherein the radar responsive tag connects to the Internet via a cellular phone.

16. The method of claim 13, wherein the radar responsive tag connects to a local area network (LAN) via a cellular phone.

17. The method of claim 12, wherein the radar responsive tag implements the E-911 call via a cellular phone with no power.

18. The method of claim 12, wherein the radar responsive tag implements the E-911 call via a cellular phone with no cellular signal.
