Abstract

An automatic emergency response system is operable to notify an emergency center of a defined event, such as a vehicle accident. The system facilitates location of the event, by using position determining means, such as GSP, to establish its at least approximate location. A control circuit includes code generating means to generate a coded signal incorporating the position location information. An alarm signal transmitter is operable on occurrence of the defined event to transmit an alarm signal incorporating the coded signal to a receiving station, which may be a satellite, which relays the message to the emergency center, including the positional information relating to the location of the transmitter. A relative low power homing signal transmitter simultaneously transmits a homing signal either continuously or at periodic intervals.

Claims

1. An automatic emergency response system operable to notify an emergency center of a defined event and to facilitate location of the event, the system including signal generating means to generate a signal incorporating information which enables location of the signal to be established, an alarm signal transmitter operable on occurrence of a defined event to transmit an alarm signal incorporating said signal to a receiving station which provides the emergency center with information relating to the signal transmission, position determining means to establish its at least approximate location, a homing signal transmitter which simultaneously transmits a homing signal either continuously or at periodic intervals, and actuating means to initiate the alarm transmitter and homing signal transmitter, the actuating means being initiated by any of the defined events.

2. The system according to claim 1 wherein the signal generating means generates a coded signal to be transmitted by the alarm signal transmitter.

3. The system according to claim 1 wherein the position determining means comprises a GPS unit that provides position information to the signal generating means on a periodic basis.

4. A system according to claim 1 wherein the position determining means comprises satellites programmed to be able to detect the homing signals transmitted by the homing signal transmitter and to provide a relatively exact location of the transmitter.

5. The system according to claim 1 wherein the position determining means comprises a cellular telephone system network.

6. The system according to claim 1 wherein the defined event includes detected accident conditions.

7. The system according to claim 1 wherein the position determining means, the alarm signal transmitter, the beacon signal transmitter and actuating means are mounted in a vehicle.

8. The system according to claim 1 wherein an inbuilt battery is associated with the transmitters to provide power in the event the vehicle battery is disconnected or exhausted.

9. The system according to claim 1 wherein the actuating means comprises one or more accelerometers, smoke detectors, motion detector, air-bag actuator. seat belt retractor, or manual switch.

10. The system according to claim 1 wherein the alarm signal transmitted incorporates additional information including accident severity, vehicle identification, passenger numbers, vehicle attitude, and updated positional information if the vehicle is in motion.

11. The system according to claim 1 wherein the homing signal transmission is a radio beacon signal transmitted at regular intervals.

12. The system according to claim 11 wherein the radio beacon transmission includes GPS position location information.

13. The system according to claim 1 wherein the homing signal transmitter includes a strobe or other bright pulsing light, or other periodic light source, or sound source, to attract attention.

14. The system according to claim 1 wherein said signal generating means includes a control circuit operatively associated with the alarm signal transmitter and homing signal transmitter, the control circuit also monitoring battery charge and adjusts the frequency of transmission rates based on the monitored battery charge.

15. A system according to claim 1 wherein the alarm signal transmitter and homing signal transmitter are a single transmitter unit switched between operational modes as required.

16. An automatic emergency response system operable to notify an emergency center of a defined event and to facilitate location of the event, the system including position determining means to establish its at least approximate location, code generating means to generate a coded signal incorporating position location information, an alarm signal transmitter operable on occurrence of a defined event to transmit an alarm signal incorporating said coded signal to a receiving station which provides the emergency center with information relating to the signal transmission, including the positional information relating to the location of the transmitter, a relative low power homing signal transmitter which simultaneously transmits a homing signal either continuously or at periodic intervals, and actuating means to initiate the alarm transmitter and homing signal transmitter, the actuating means being initiated by any of the defined events.

17. The system according to claim 16 wherein the position determining means comprises a GPS unit that provides position information to the signal generating means on a periodic basis.

18. The system according to claim 16 wherein the position determining means comprises a cellular telephone system network.

19. The system according to claim 16 wherein the defined event includes detected accident conditions.

20. The system according to claim 16 wherein the position determining means, the alarm signal transmitter, the homing signal transmitter and actuating means are mounted in a vehicle.

21. The system according to claim 16 wherein an inbuilt battery is associated with the transmitters to provide power in the event the vehicle battery is disconnected or exhausted.

22. The system according to claim 16 wherein the actuating means comprises one or more accelerometers, smoke detectors, motion detector, air-bag actuator. seat belt retractor, or manual switch.

23. The system according to claim 16 wherein the coded alarm signal transmitted incorporates additional information including accident severity, vehicle identification, passenger numbers, vehicle attitude, and updated positional information if the vehicle is in motion.

24. The system according to claim 16 wherein the homing signal transmission is a radio beacon signal transmitted at regular intervals.

25. The system according to claim 24 wherein the radio beacon transmission included GPS position location information.

26. The system according to claim 16 wherein he homing signal transmitter includes a strobe or other bright pulsing light, or other periodic light source, or sound source, to attract attention.

27. The system according to claim 16 wherein said code generating means includes a control circuit operatively associated with the alarm signal transmitter and homing signal transmitter, the control circuit also monitoring battery charge and adjusts the frequency of transmission rates based on the monitored battery charge.
