Disaster alert device and system
First Claim
1. A disaster alert system comprisingA) at least one central station for transmitting disaster alert information by radio directed at disaster alert devices at use locations in specific at-risk regions defined by latitude and longitude,B) a plurality of disaster alert devices, each device adapted for use at a use location in a disaster alert system, with each disaster alert device comprising:
- 1) a radio receiver,2) an audio unit for alerting persons located at the use location to the precise nature of a disaster, and3) a processor comprising a memory unit with latitude and longitude of the use location stored therein, wherein said processor is;
a) programmed to monitor radio transmissions from a central station for disaster alerts directed to all disaster alert devices located within an at-risk region defined by latitude and longitude information,b) programmed to compare the latitude and longitude information transmitted by the central station with the latitude and longitude information stored in its memory unit to determine if a message is directed to the disaster alert unit, andc) programmed to provide a voice warning via said audio unit of the nature of potential or actual risks to people at the use location based on information received by the disaster alert device from the central station when and only when the disaster alert device is among the disaster alert devices to which a transmission from the central station is directed.

Abstract
A disaster alert system and disaster alert devices for use in the system. Each disaster alert device includes a radio receiver, and a processor programmed to monitor radio transmissions from one or more central stations for disaster alerts directed to the location of the disaster alert device. Each alert device also includes an audio unit to alert personnel located at the site of the device to the precise nature of the disaster. The disaster alert devices are pre-programmed with information identifying the precise use location of the warning device. This use location information includes latitude and longitude of the use location and may also include other location information such as street address and zip code. Warnings are broadcast from central stations identifying with latitude and longitude information specific at-risk regions to which the warnings are directed which could be, for example, nationwide, statewide, countywide, or to much smaller regions, such as several houses on a single street or even a single residence. Each disaster alert device is preferably programmed to ignore all warnings directed to at-risk regions that do not include the latitude and longitude of the use location of the device.
