Emergency alert system and method
View Patent ↗An emergency alert system, method and device 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 emergency alert enabled device that receives both the emergency alert message and the geographic area message. The emergency alert enabled 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. An emergency alert enabled device, comprising:
a. an alert message receiver;
b. a means for determining a real-time location of the emergency alert enabled device; and,
c. a processor configured to perform the following tasks:
i. authenticate a geographically targeted alert message received by the alert message receiver;
ii. determine whether the emergency alert enabled device is located within a geographic area of concern, using data from the means for determining a real-time location of the emergency alert enabled device, wherein the geographic area of concern is defined in relation to the nature of the alert message; and,
iii. present an alert to a user if the emergency alert enabled device is located within the geographic area of concern;
wherein the processor comprises:
i. a first processor unit for reassembling parts of received messages, if necessary, and authenticating incoming messages, wherein the first processor unit is configured to remain in standby mode, and thus ready to receive incoming messages, during all operations; and,
ii. a second processor unit for determining whether the emergency alert enabled device is located within a geographic area of concern, and if so, for presenting an alert to a user, wherein the second processor is configured to be powered on only when the first processor unit has determined that an authentic message has been received.
2. The device of claim 1 , further comprising an antenna, wherein the alert message receiver is configured to receive signals from the antenna.
3. The device of claim 2 , wherein the alert message receiver and the means for determining a real-time location of the emergency alert enabled device are both configured to receive signals from the antenna.
4. The device of claim 1 , wherein the emergency alert enabled device is embedded in a host device.
5. The device of claim 4 , wherein the emergency alert enabled device is configured to receive messages via an antenna used by the host device.
6. The device of claim 4 , wherein the emergency alert enabled device is powered by the same power supply that powers the host device.
7. The device of claim 4 , wherein the host device is capable of transmitting data to the emergency alert enabled device.
8. The device of claim 1 , wherein the means for determining a real-time location of the emergency alert enabled device comprises a GPS module.
9. The device of claim 1 , wherein the emergency alert enabled device is capable of using speech to text technology to provide text alert messages to users.
10. The device of claim 1 , wherein the emergency alert enabled device is capable of using text to speech technology to provide audible alert messages to users.
11. The device of claim 1 , wherein the emergency alert enabled device is capable of producing a vibration alert.
12. The device of claim 1 , wherein the means for determining a real-time location of the emergency alert enabled device is capable of determining the emergency alert enabled device's real-time location when the device is indoors, in inclement weather, or in a congested urban location.
13. The device of claim 1 , wherein the emergency alert enabled device retains prior location data during periods in which accurate, real-time location data is not available, and the device uses the most recent, accurate location data to determine whether the device is within the geographic area of concern.
14. The device of claim 1 , wherein the emergency alert enabled device may be upgraded by the user.
15. The device of claim 1 , wherein the received geographically targeted alert message contains a priority code.
16. The device of claim 15 , wherein the priority code is based on a preselected set of codes associated with situations of differing severity.
