Abstract

A method of communicating a geographically targeted emergency alert message is disclosed. The invention employs a method of using an emergency alert message, wherein the message directs end users to take appropriate action like evacuating an identified geographic area. The invention further employs a method of using a geographic area message, the message being based on a particular geographic area within which all persons should receive the emergency alert message. An emergency alert enabled device that receives both the emergency alert message and the geographic area message is also used in the invention. The emergency alert enabled device is used to determine whether it is located within the geographic area of concern, and if so, presents the emergency alert message to the end user.

Claims

1. A method of communicating a geographically targeted emergency alert message, comprising:

a) identifying an emergency situation warranting notification of persons within a geographic area of concern;

b) defining the geographic area of concern;

c) creating a geographic area message that represents the geographic area of concern;

d) selecting or creating an emergency alert message;

e) transmitting the geographic area message and the emergency alert message to a satellite;

f) retransmitting the emergency alert message and the geographic area message by the satellite to the earth;

g) receiving the retransmission of the emergency alert message and the geographic area message by an emergency alert enabled device;

h) turning on the emergency alert enabled device if the emergency alert enabled device was off when the retransmission of the emergency alert message and the geographic area message was received by the emergency alert enabled device;

i) fixing the geographic position of the emergency alert enabled device;

j) performing an analysis of the geographic area message and the geographic position of the emergency alert enabled device to determine whether the emergency alert enabled device is located within the geographic area of concern; and

k) presenting the emergency alert message if and only if the emergency alert enabled device is located within the geographic area of concern.

2. A method of communicating a geographically targeted emergency alert message, comprising:

a) transmitting an emergency alert message and a geographic area message to a satellite, the geographic area message representing a geographic area of concern;

b) retransmitting the emergency alert message and the geographic area message by the satellite to the earth;

c) receiving the retransmission of the emergency alert message and the geographic area message by an emergency alert enabled device; and

,

d) presenting the emergency alert message if and only if the emergency alert enabled device is located within the geographic area of concern.

3. The method of claim 2, wherein the emergency alert message is selected from a set of prepared alert messages.

4. The method of claim 3, wherein the emergency alert message is selected by an emergency system operator.

5. The method of claim 2, wherein the geographic area message is compressed before it is transmitted to the satellite.

6. The method of claim 2, further comprising the steps of:

a) fixing the geographic position of the emergency alert enabled device using global positioning system (GPS) satellite signals; and

,

b) performing an analysis of the geographic area message and the geographic position of the emergency alert enabled device to determine whether the emergency alert enabled device is located within the geographic area of concern.

7. The method of claim 2, wherein the emergency alert enable device is embedded in a host device.

8. The method of claim 7, further comprising the step of turning on the host device in the event an emergency alert message is to be presented to a user.

9. The method of claim 2, further comprising the steps of:

a) selecting the emergency alert message at an emergency operations center; and

,

b) creating the geographic area message at the emergency operations center or at an emergency transmission center.

10. The method of claim 9, wherein one emergency transmission center serves more than one emergency operations center.

11. The method of claim 2, wherein the geographic area message is transmitted to the satellite in two or more parts.

12. A method of communicating a geographically targeted emergency alert message, comprising:

a) transmitting an emergency alert message selected from a set of prepared alert messages and a geographic area message to a satellite the geographic area message representing a geographic area of concern;

b) retransmitting the emergency alert message and the geographic area message by the satellite to the earth;

c) receiving the retransmission of the emergency alert message and the geographic area message by an emergency alert enabled device;

d) presenting the emergency alert message if the emergency alert enabled device is located within the geographic area of concern;

e) saving the emergency alert message that was presented; and

f) presenting the saved emergency alert message to a user at a time subsequent to the initial presentation of the message.

13. A method of communicating a geographically targeted emergency alert message, comprising:

a) transmitting an emergency alert message selected from a set of prepared alert messages and a geographic area message to a satellite, the geographic area message representing a geographic area of concern;

b) retransmitting the emergency alert message and the geographic area message by the satellite to the earth;

c) receiving the retransmission of the emergency alert message and the geographic area message by an emergency alert enabled device;

d) presenting the emergency alert message if the emergency alert enabled device is located within the geographic area of concern;

e) saving the emergency alert message and geographic area message in the emergency alert enabled device for a specified period of time; and

f) fixing the geographic location of the emergency alert enabled device at preselected time intervals during the specified period of time.

14. A method of communicating a geographically targeted emergency alert message, comprising:

a) transmitting an emergency alert message selected from a set of prepared alert messages and a geographic area message to a satellite, the geographic area message representing a geographic area of concern;

b) retransmitting the emergency alert message and the geographic area message by the satellite to the earth;

c) receiving the retransmission of the emergency alert message and the geographic area message by an emergency alert enabled device;

d) presenting the emergency alert message if the emergency alert enabled device is located within the geographic area of concern; and

wherein the satellite retransmits the emergency alert message and geographic area message periodically during a specified period of time.

15. The method of claim 14, wherein the specified period of time is selected by an operator based on the nature of the emergency.

16. A method of communicating a geographically targeted emergency alert message, comprising:

a) selecting or creating an emergency alert message;

b) creating a geographic area message representative of a geographic area of concern;

c) transmitting the emergency alert message and geographic area message;

d) receiving the emergency alert message and geographic area message by an emergency alert enabled device;

e) processing the geographic area message to determine whether the emergency alert enabled device is located within the geographic area of concern; and

,

f) presenting the emergency alert message to a user if and only if the emergency alert enabled device is located within the geographic area of concern.

17. The method of claim 16, wherein the emergency alert message and the geographic area message are transmitted to a satellite, and the emergency alert message and the geographic area message are retransmitted to the earth from the satellite.

18. The method of claim 16, further comprising the step of fixing the geographic position of the emergency alert enabled device using the global positioning system (GPS).
