Storm alert for emergencies
DCFirst Claim
1. A geographically specific signal communication system comprising:
- (a) location encoding means operable to select at least one of a plurality of geographic areas and to generate a location code signal component;
(b) communication signal means operable to generate a communication signal component;
(c) broadcast means having said location encoding means and said communication signal means coupled thereto and generating a broadcast signal including said location code signal component and said communication signal component;
(d) receiver means positioned in one of said geographic areas and configured to receive said broadcast signal and extract said location code signal component and said communication signal component therefrom;
(e) communication signal processor means coupled to said receiver means and operable, when activated, to process said communication signal component;
(f) location code set means coupled to said receiver means and enabling user entry of a location code corresponding to one of said geographic areas; and
(g) location decode means coupled to said receiver means and cooperating with said code set means to process said location code signal component to determine if it corresponds to the user entered location code and, if so, activating said communication processor means to process said communication signal component.

Abstract
A geographically specific emergency alert system includes a code generator unit in which geographic areas to be alerted and types of severity of alerts are selected and code strings generated to represent the affected areas and alert types selected. The code strings are broadcast by modulating the audio carrier of a television signal and received on receiver units positioned in areas within the broadcast market of a television station providing the alerting service. Location codes or entered into the receiver units by the users according to the areas in which the receiver units are used. When an alert is broadcast, each receiver unit decodes a location code string in the signal. If it matches that set on the receiver, an alert code string is decoded to activate a alarm devices connected to the receiver, such as an audible alarm generator, LED, etc., in accordance with the type or severity of alert that was broadcast.

9. An emergency warning system comprising:
-
(a) location select means operable to select at least one of a plurality of geographic areas; (b) alert select means operable to select a type of alert condition; (c) code generator means having said location select means and said alert select means coupled thereto combining a location code string corresponding to the geographic area selected by said location select means and an alert code string corresponding to the type of alert condition selected by said alert select means; (d) broadcast means having said code generator means coupled thereto and broadcasting a broadcast signal incorporating said composite code string; (e) at least one alert receiver means positioned in one of said geographic areas and operative to receive said broadcast signal and extract said composite code string therefrom; (f) alarm means coupled to said receiver means and operative, when activated, to process said alert code string and generate an alarm signal; (g) said receiver means including location code set means enabling use entry of a location code corresponding to one of said geographic areas; and (h) location decode means coupling said alarm means to said receiver means and having said location code set means coupled thereto, said location decode means being operative to compare said location code string in the received composite code string with the user entered location and, upon matching, activating said alarm means to generate said alarm signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. An emergency warning receiver unit for receiving broadcast signal incorporating a composite code string including a location code string representing one of a plurality of geographic areas and an alert code string representing a type of alert, said receiver comprising:
-
(a) broadcast signal demodulation means operative to receive said broadcast signal and extract said composite code string therefrom; (b) alarm means coupled to said demodulation means and operative, when activated, to process said alert code string and generate an alarm signal; (c) location code set means coupled to said demodulation means and enabling user entry of a location code corresponding to one of said geographic areas; and (d) location decode means coupled with said demodulation means and said location code set means and operative to compare said location code string in the received composite code string with the user entered location code and, upon matching, activating said alarm means to generate said alarm signal. - View Dependent Claims (19, 20, 21, 22, 23)
