Abstract

Disclosed herein are methods and systems for displaying alerts in a web browser. An alert repeater is configured to receive an alert from an alert provider. A geographical determiner is configured to determine an effective geographical area for the alert. The alert repeater sends the alert over a browser update communication channel to an alert receiver in a web browser within effective geographical area. The alert receiver then displays the alert in the web browser.

Claims

1. A system of alerting comprising:

an alert repeater, configured to;

receive an alert over a communication channel from an alert provider, and

send the alert to an alert receiver over a browser update communication channel, wherein the browser update communication channel comprises a dedicated communication channel configured for providing updates to a web browser, and wherein the alert receiver has been installed in the web browser without any user interaction and the alert receiver is configured to display the alert in the web browser; and

a geographical determiner configured to;

determine an effective geographical area for the alert, and

limit the alert to the effective geographical area, wherein the alert is only sent to an alert receiver located in the effective geographical area.

2. The system of claim 1, wherein the geographical determiner is configured to determine an effective geographic area for the alert based upon IP geolocation.

3. The system of claim 1, wherein the geographical determiner is configured to determine an effective geographic area for the alert based upon a location entered by a user.

4. The system of claim 1, wherein the alert receiver is installed natively in the web browser.

5. The system of claim 1, wherein the alert comprises an information link to a website containing additional information about the alert.

6. The system of claim 1, wherein the alert provider is a governmental entity.

7. The system of claim 1, wherein the alert is a public safety alert.

8. The system of claim 1, wherein the alert comprises an expiration time, and the alert receiver is further configured to display the alert within the expiration time.

9. The system of claim 1, wherein the browser update communication channel uses a polling-based communication protocol.

10. The system of claim 1, wherein the browser update communication channel uses a push-based communication protocol.

11. The system of claim 1, wherein a service executing externally to the web browser comprises the alert receiver.

12. A method of receiving alerts in a web browser comprising:

receiving an alert in an alert receiver from an alert repeater, wherein;

the alert is received from the alert repeater over a browser update communication channel, wherein the browser update communication channel comprises a dedicated communication channel configured for providing updates to the web browser,

the alert receiver is within an effective geographical area of the alert, and

the alert receiver has been installed without any user interaction in the web browser; and

displaying the alert in the web browser.

13. The method of claim 12, wherein the alert receiver is installed natively in the web browser.

14. The method of claim 12, wherein the alert is displayed in a status bar in the web browser.

15. The method of claim 12, wherein the alert comprises an information link to a website containing additional information about the alert.

16. The method of claim 12, wherein the alert is further comprises an expiration time, and the alert receiver is further configured to display the alert within the expiration time.

17. The method of claim 12, wherein receiving an alert in an alert receiver comprises:

receiving an alert via a service executing externally to the web browser.

18. The method of claim 12, further comprising:

restoring the web browser window if an alert is received by the alert receiver while the web browser window is minimized.

19. The method of claim 12, further comprising:

opening the web browser if an alert is received by the service while the web browser is closed.

20. A method of sending alerts in a web browser comprising:

receiving an alert in an alert repeater from an alert provider;

determining an effective geographical area for the alert; and

sending the alert using a browser update communication channel to an alert receiver within the effective geographical area for the alert, wherein the browser update communication channel comprises a dedicated communication channel configured for providing updates to the web browser, and wherein the alert receiver has been installed without any user interaction in the web browser.

21. The method of claim 20, wherein determining an effective geographical area for the alert comprises:

determining an effective geographical area for the alert based upon IP geolocation.

22. The method of claim 20, wherein determining an effective geographical area for the alert comprises:

determining an effective geographical area for the alert based upon a location entered by a user.

23. The method of claim 20, wherein the alert provider is a governmental entity.

24. The method of claim 20, wherein the alert is a public safety alert.

25. The method of claim 20, wherein the browser update communication channel uses a polling-based communication protocol.

26. The method of claim 20, wherein the browser update communication channel uses a push-based communication protocol.
