Emergency alert system and method
View Patent ↗An electronic device, computer-implemented method, and computer program product for providing emergency alerts are disclosed. The invention employs an emergency alert message, which directs end users to take some particular action like evacuating an identified geographic area. The invention further employs a geographic area message, which is based on a particular geographic area within which all persons should receive the emergency alert message. The invention utilizes an electronic device that receives both the emergency alert message and the geographic area message. The electronic device determines whether it is located within the geographic area of concern, and if so, presents the emergency alert message to the end user.
1. A handheld electronic device comprising tangible, machine-readable media comprising executable code to perform the steps of:
a. receiving an emergency alert message and geographic area message;
b. authenticating incoming messages;
c. determining whether the electronic device is located within a geographic area of concern using location data from the electronic device; and,
d. presenting the emergency alert message to a user only if the electronic device is located within the geographic area of concern or within a user specified geographic area of concern.
2. The handheld electronic device of claim 1 wherein a unique identifier is assigned to the emergency alert message, the geographic area message, or both messages.
3. The handheld electronic device of claim 2 wherein the unique identifier is a serial number.
4. The handheld electronic device of claim 3 wherein the tangible, machine-readable media further comprises executable code to perform the steps of:
a. re-presenting the emergency alert message to the user after a specified amount of time if the electronic device is located within the geographic area of concern or within a user specified geographic area of concern.
5. The handheld electronic device of claim 4 wherein the geographic area of concern is based, at least in part, on factors taken from the following group: the nature of the emergency; the severity of the threat posed by the emergency; weather conditions; geographic jurisdiction of the authority issuing the emergency alert message; population; evacuation routes; and, topography.
6. The handheld electronic device of claim 5 wherein the tangible, machine-readable media further comprises executable code to perform the steps of:
a. determining if the electronic device is moving; and, if the handheld electronic device is moving, estimating the electronic device's projected movement with time; and,
b. presenting the user with the emergency alert message if the electronic device approaches an active geographic area of concern.
7. A computer-implemented method for providing emergency alerts comprising:
a. a computer comprising tangible, machine-readable media comprising executable code to perform the steps of:
i. selecting or creating a primary emergency alert message;
ii. creating a geographic area message representative of a geographic area of concern; and
iii. transmitting the emergency alert message and geographic area message;
b. an electronic device comprising tangible, machine-readable media comprising executable code to perform the steps of:
i. receiving the emergency alert message and the geographic area message
ii. authenticating incoming messages;
iii. determining whether the electronic device is located within the geographic area of concern using location data from the handheld electronic device; and,
iv. presenting the emergency alert message to a user only if the electronic device is located within the geographic area of concern or within a user specified geographic area of concern.
8. The computer-implemented method of claim 7 wherein the tangible, machine-readable media further comprises executable code to perform the steps of:
a. re-presenting the emergency alert message to the user after a specified amount of time if the electronic device is located within the geographic area of concern or within a user specified geographic area of concern.
9. The computer-implemented method of claim 8 wherein the emergency alert message is transmitted via Internet.
10. The computer-implemented method of claim 8 wherein the emergency alert message is transmitted via cellular network.
11. The computer-implemented method of claim 8 wherein the geographic area of concern is based, at least in part, on factors taken from the following group: the nature of the emergency; the severity of the threat posed by the emergency; weather conditions; geographic jurisdiction of the authority issuing the emergency alert message; population; evacuation routes; and, topography.
12. The computer-implemented method of claim 11 wherein the electronic device further comprises executable code to perform the steps of:
a. determining if the electronic device is moving; and, if the electronic device is moving, estimating the electronic device's projected movement with time; and,
b. presenting the user with the emergency alert message if the electronic device approaches an active geographic area of concern.
13. A computer program product comprising a tangible non-transitory computer readable storage medium having instructions stored therein for causing an electronic device to alert a user of an emergency, said instructions comprising:
a. receiving an emergency alert message and geographic area message;
b. authenticating incoming messages;
c. determining whether the electronic device is located within a geographic area of concern using location data from the electronic device; and,
d. presenting the emergency alert message to a user only if the electronic device is located within the geographic area of concern or within a user specified geographic area of concern.
14. The computer program product of claim 13 wherein a unique identifier is assigned to the emergency alert message, the geographic area message, or both messages.
15. The computer program product of claim 14 , wherein the unique identifier is a serial number.
16. The computer program product of claim 15 wherein the instructions further comprise:
a. re-presenting the emergency alert message to the user after a specified amount of time if the electronic device is located within the geographic area of concern or within a user specified geographic area of concern.
17. The computer program product of claim 13 wherein the geographic area of concern is based, at least in part, on factors taken from the following group: the nature of the emergency; the severity of the threat posed by the emergency; weather conditions; geographic jurisdiction of the authority issuing the emergency alert message; population; evacuation routes; and, topography.
18. The computer program product of claim 17 wherein the instructions further comprise:
a. determining if the electronic device is moving; and, if the electronic device is moving, estimating the electronic device's projected movement with time; and,
b. presenting the user with the emergency alert message if the electronic device approaches an active geographic area of concern.
19. The computer program product of claim 18 wherein the electronic device is a handheld electronic device.
