ALERT SYSTEM AND PERSONAL APPARATUS
First Claim
1. An electronic warning receiver comprising:
- a wakeup antenna for receiving a broadcast wakeup signal;
a first receiver coupled to said wakeup antenna for decoding said broadcast wakeup signal;
a monitor circuit coupled to said first receiver and responsive to said decoded wakeup signal to activate a power supply controller;
said power supply controller for applying power to the electronic warning receiver;
a second antenna for receiving a broadcast warning message;
a second receiver coupled to said second antenna for decoding said broadcast warning message, anda microprocessor coupled to said second receiver and responsive to said decoded message to activate LEDs, a text message and/or an audible alarm indicative of the warning message received.

Abstract
An alert system and apparatus for an emergency alert system is provided to disseminate emergency information to the public utilizing a universal paging system through a personal alert device such as a cellular telephone, pager, PDA or E-FOB. The alert system utilizes an emergency alert system signal from the NOAA alert system to broadcast the alert message to cellular devices in a specified alert area. The broadcast message provides information related to the alert level. The E-FOB may be a passive device which is activated by a NOAA alert signal and then listens for a cellular message. If the E-FOB is within the alert area, the E-FOB provides information to the user. If the E-FOB is not within the alert area, the E-FOB returns to a passive state.

13. A method of disseminating emergency information comprising the steps of:
-
receiving event transmission information by a first receiver indicative of an emergency within a geographic area; receiving a broadcast signal within said geographic area by a wakeup antenna; providing a wakeup signal in response to receiving said broadcast signal by said wakeup antenna to activate a passive receiving device within said geographic area; extracting an event code and location code from said event transmission information by said first receiver; identifying the nature of said emergency from said event code by said first receiver; identifying at least one transmitter within a predetermined distance of a specified location identified by said location code within a portion of said geographic area by said first receiver; formatting said event code corresponding to said emergency by said first receiver; broadcasting said event code by said at least one transmitter, receiving said event code broadcast from said at least one transmitter by said passive receiving device if said passive receiving device is within said portion of said geographic area; and deactivating said passive receiving device if said event code broadcast by said at least one transmitter is not received within a predetermined period of time. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
