Abstract

An efficient method and apparatus to receive broadcasted emergency alerts using portable handheld devices or mobile devices that are operable to provide a user with relevant alerts based on the user'"'"'s relevant position, in a low-powered, always-on manner are presented. Using the always on partitions of both the receiver and the system on chip (SOC) of a mobile device, embodiments of the present invention are capable of determining whether or not the remainder of the circuits of a mobile device need to be powered on in order to record audio data associated with an alert, when the alert is received. Furthermore, embodiments of the present invention are operable for displaying these alerts in a manner such that a user is notified that a relevant alert has been received and placing the user in a position where the user must address the alert notification and take appropriate action.

Claims

1. A computer implemented method of generating a notification, said method comprising:

detecting an emergency message from an FM radio band, wherein said detecting is performed using a first radio circuit within a mobile device;

determining if said message concerns a predetermined geographical region using a first portion of a computer system within said mobile device responsive to said detecting;

provided said message concerns said predetermined geographical region, powering up a second radio circuit within said mobile device and powering up a second portion of said computer system;

receiving and decoding said emergency message using said second radio circuit, wherein said emergency message comprises an audio signal;

storing said audio signal into a memory of said computer system; and

generating an alert notification concerning said emergency message on said mobile device.

2. The method as described in claim 1 wherein said storing and said generating are performed by said second portion of said computer system.

3. The method as described in claim 1 wherein said emergency message is a National Weather Service message.

4. The method as described in claim 1 wherein said alert notification is a visual notification displayed on a display screen of said mobile device.

5. The method as described in claim 1 wherein said alert notification is a visual notification displayed on a light emitting component of said mobile device.

6. The method as described in claim 4 wherein said visual notification remains displayed on said display screen until a user interaction is performed responsive to said visual notification.

7. The method as described in claim 5 wherein said visual notification remains displayed on said light emitting component until a user interaction is performed responsive to said visual notification.

8. The method as described in claim 1, wherein said determining further comprises:

comparing a relevant location of said mobile device to said predetermined geographical region;

determining whether said relevant location of said mobile device is in said predetermined geographical region.

9. A mobile device for generating a notification, said apparatus comprising:

a plurality of radio circuits, wherein a first radio circuit is operable to detect an emergency message from an FM radio band;

a computer system, wherein a first portion of said computer system is operable to make a determination if said message concerns a predetermined geographical region responsive to a detection of said emergency message from said first radio circuit;

a second radio circuit from said plurality of radio circuits, wherein said second circuit is operable to receive and decode said emergency message wherein said emergency message comprises an audio signal;

a wake-up circuit operable to provide power to said second radio circuit and a second portion of said computer system responsive to said determination made by said first portion of said computer system;

a memory of said computer system, wherein said memory is operable to store said audio signal; and

a user alert module for generating an alert notification concerning said emergency message on said mobile device.

10. The mobile device described in claim 9 wherein said emergency message is a National Weather Service message.

11. The mobile device described in claim 9 wherein said user alert module comprises a display screen and wherein said alert notification is a visual notification displayed on said display screen.

12. The mobile device described in claim 9 wherein said alert notification is a visual notification displayed on a light emitting component of said mobile device.

13. The mobile device described in claim 11 wherein said visual notification remains displayed on said display screen until a user interaction is performed responsive to said visual notification.

14. The mobile device described in claim 12 wherein said visual notification remains displayed on said light emitting component until a user interaction is performed responsive to said visual notification.

15. The mobile device described in claim 9, wherein said first portion of said computer system further comprises:

a comparison module for comparing a relevant location of said mobile device to said predetermined geographical region, wherein said comparison module is coupled to said memory unit; and

a determination module for determining whether said relevant location of said mobile device is in said predetermined geographical region, wherein said determination module is coupled to said memory unit.

16. A computer implemented method of generating a notification, said method comprising:

detecting an emergency message from a radio band using a receiver coupled to a first receiver circuit, wherein said receiver is operable to detect said signal within a mobile device;

determining if said message concerns a predetermined geographical region using a user alert module coupled to a first portion of a computer system within said mobile device responsive to said detecting;

provided said message concerns said predetermined geographical region, powering up a second radio circuit within said mobile device and a second portion of said computer system;

receiving and decoding said emergency message using said second radio circuit, wherein said emergency message comprises an audio signal;

storing said audio signal into a memory of said computer system; and

generating an alert notification using said user alert module.

17. The method as described in claim 16 wherein said storing and said generating are performed by said second portion of said computer system and wherein said radio band is an FM radio band.

18. The method as described in claim 16 wherein said emergency message is a National Weather Service message.

19. The method as described in claim 16 wherein said alert notification is a visual notification displayed on a display screen of said mobile device.

20. The method as described in claim 16 wherein said alert notification is a visual notification displayed on a light emitting component of said mobile device.

21. The method as described in claim 19 wherein said visual notification remains displayed on said display screen until a user interaction is performed responsive to said visual notification.

22. The method as described in claim 20 wherein said visual notification remains displayed on said light emitting component until a user interaction is performed responsive to said visual notification.

23. The method as described in claim 16, wherein said determining further comprises:

comparing a relevant location of said mobile device to said predetermined geographical region;

determining whether said relevant location of said mobile device is in said predetermined geographical region.
