Abstract

A location aware mobile device may include an accelerometer or similar motion sensing component that can measure changes in speed or direction. An application executing in the mobile device can determine whether particular motion changes are indicative of the mobile device being involved in a crash event. If the motion parameters indicate that a crash event has occurred, the mobile device can communicate a crash event notification to a server, which can alert an emergency response unit about the crash, including the crash location, without the need for human intervention. Verification of the crash event may be performed at the server in a variety of ways, including the simultaneous receipt of crash event notifications from multiple co-located devices.

Claims

1. A method for indicating a crash event comprising:

detecting a crash event in a mobile device; and

communicating an indication of the crash event to a server.

2. The method according to claim 1 wherein detecting a crash event comprises measuring at least one motion parameter of the mobile device and comparing the at least one motion parameter to a threshold.

3. The method according to claim 1 wherein communicating an indication of the crash event comprises communicating a location of the mobile device.

4. The method according to claim 1 comprising alerting an emergency response unit of the crash event from the server.

5. The method according to claim 1 comprising verifying the crash event in the server.

6. The method according to claim 5 wherein verifying the crash event comprises:

receiving a plurality of crash event indications from a plurality of mobile devices at the server; and

correlating at least one of time data or location data of the plurality of crash event indications.

7. The method according to claim 5 wherein verifying the crash event comprises comparing motion data of a first mobile device with motion data of a second mobile device.

8. The method according to claim 5 wherein verifying the crash event comprises providing a query from the server to the mobile device.

9. The method according to claim 7 wherein verification of a crash event is dependent on a response to the query from the mobile device or a lack of a response to the query from the mobile device.

21. The method according to claim 1 wherein the mobile device will initiate a notification using Bluetooth

22. The method according to claim 21 wherein the Bluetooth notification can be transmitted/broadcast through a separate audio device

23. The method according to claim 22 wherein the separate audio device can be automobile speakers.

24. The method according to claim 1 wherein the mobile device will initiate a notification upon the deployment of an airbag.

10. A server configured to:

receive motion data from at least one mobile device;

determine that the motion data indicates a crash event; and

provide a notification of the crash event to at least one emergency response unit.

11. The server according to claim 10 wherein the motion data comprises a crash event notification that indicates that the motion data has met a crash event threshold.

12. The server according to claim 11 configured to:

receive a plurality of crash notifications from a plurality of mobile devices; and

correlate at least one of time data and location data of the plurality of crash notifications to verify the crash event.

13. The server according to claim 11 configured to provide a verification query to the mobile device in response to receiving the crash event notification.

14. The server according to claim 10 configured to:

receive motion data from a plurality of mobile devices; and

compare motion data of the plurality mobile devices to determine a crash event.

15. The server according to claim 14 wherein the motion data of a mobile device comprises a location of the mobile device and at least one impact indicating parameter of the mobile device, and wherein the server is configured to verify that a crash event has occurred if motion data of a plurality of mobile devices indicates a common location and at least one common impact indicating parameter.

16. The server according to claim 14 wherein the motion data of a mobile device comprises a location of the mobile device and at least one impact indicating parameter of the mobile device, and wherein the server is configured to determine that a crash event has not occurred if motion data of a plurality of mobile devices at a common location indicates that only one of the plurality of mobile devices has undergone an impact.

17. A computer-readable medium comprising computer-executable instructions for execution by a processor of a mobile device, that, when executed, cause the processor to:

determine at least one motion parameter of the mobile device;

determine if the at least one motion parameter meets a crash indicating threshold; and

communicate at least one of the at least one motion parameter or a crash event notification to a server.

18. The computer-readable medium according to claim 17 comprising instructions that, when executed by the processor, cause the processor to determine that a location of the mobile device correlates to a roadway and that an acceleration of the mobile device correlates to a motor vehicle accident event.

19. The computer-readable medium according to claim 17 comprising instructions that, when executed by the processor, cause the processor to indicate the location of the mobile device to the server.

20. The computer-readable medium according to claim 17 comprising instructions that, when executed by the processor, cause the processor to periodically communicate a location indicating signal to the server to notify the server of the location of a crash event.
