Abstract

A system for sending an effective warning signal to receivers in a predetermined area. A transmitter, activated by a local authority, sends a severe weather warning signal to a plurality of receivers. Cities or counties within the predetermined area are divided into subdivisions thereof called sectors, each of which represents an area that is selectively addressable by the transmitter. Each of the receivers has a programmable sector code which has been programmed according to the location of the home or office in which it is placed. When activated, the transmitter sends radio frequency warning signals which contain digitally encoded information indicating the sector to which the warning applies. Upon receiving the warning signal, each receiver that has been programmed with the sector code being transmitted responds by generating an audible alert or other warning signal. In one embodiment, the transmitter sending the warning signal is connected to, and activated by, the same mechanism that activates a corresponding warning siren.

Claims

1. A system for providing notification of severe weather, the system comprising:

a transmitter configured to transmit at least one notification signal for the notification comprising type data indicating a type of severe weather and area designation data for a specific area comprising at least one member of a group consisting of sector data indicating a sector in which the severe weather is expected and city/county data indicating a city/county in which the severe weather is expected and to transmit a test signal at a regular interval; and

a plurality of receivers each configured to receive and process the at least one notification signal and, if configured to cover an area corresponding to the specific area identified in the area desienation data, to cause an alarm to be triggered for the type of severe weather for the specific area, wherein each of the receivers comprises a timer configured to time out in a period greater than the regular interval of the test signal, to generate a trouble alarm upon timing out, and to reset upon receiving the test signal.

2. The system of claim 1, further comprising an emergency warning mechanism configured to activate the transmitter for transmitting the at least one notification signal and to active a siren when the transmitter is activated.

3. The system of claim 2, wherein the emergency warning mechanism comprises a control unit configured to activate the transmitter and the siren.

4. The system of claim 2, wherein the omergency warning mechanism is controlled by a local authority.

5. The system of claim 1, further comprising at least one authority to activate the transmitter, the authority comprising at least one member of a group consisting of a municipality in which the specific area is located and a county in which the specific area is located.

6. A system for providing notification of severe weather for a specific area comprising:

a warning siren;

a transmitter configured to transmit a notification signal for the notification comprising weather sector data indicating the specific area in which the severe weather is expected and type data indicating a type of the severe weather and to transmit a test signal at a regular interval; and

a plurality of receivers in the specific area tuned to a frequency transmitted by the transmitter, each programmed with receiver sector data corresponding to a geographic area and each configured to cause an alert to be triggered for the type of severe weather if the weather sector data matches the receiver sector data, wherein each of the receivers comprises a timer configured to time out in a period greater than the regular interval of the test signal, to generate a trouble alarm upon timing out, end to reset upon receiving the test signal;

wherein the siren and the transmitter are activated by an entity authorized to provide the notification for the specific area.

7. The system of claim 6, wherein the receiver sector data for each receiver comprises a code for a location of the receiver.

8. The system of claim 6, further comprising a control unit configured to active the transmitter and the siren.

9. A system for selective notification of severe weather for a specific area comprising:

a warning siren;

a transmitter configured to transmit at least one notification signal for the notification and to transmit a test signal at a regular interval, the notification signal comprising sector data indicating the specific area in which the severe weather is expected and type data indicating a type of the severe weather;

a control unit configured to activate to siren and the transmitter in response to an indication of the severe weather for the specific area; and

a plurality of receivers each configured to receive the notification signal and to cause an alarm to be trigger for the type of severe weather if the sector data indicates the receiver is to trigger activation of the alarm for the specific area, wherein each of the receivers comprises a timer configured to time out in a period greater than the regular interval of the test signal, to generate a trouble alarm upon timing out, and to reset upon receiving the test signal.

10. A method for selective notification of severe weather for a specific area comprising the steps of:

transmitting a notification signal for the notification comprising type data indicating a type of the severe weather and area designation data comprising at least one member of a group consisting of sector data indicating a sector in which the severe weather is expected and city/county data indicating a city/county in which the severe weather is expected;

receiving the notification signal for at least one receiver and, in response, causing a warning alarm to be triggered for the type of weather if the at least one receiver is programmed with the area designation data; and

transmitting, at a regular interval, a test signal that prevents a trouble alarm in the at least one receiver from being generated if the test signal is received by the at least one receiver.

11. The method of claim 10, wherein:

the area designation data comprises a code indicating the specific area, and the at least one receiver is located in the specific area.

12. The system of claim 10, further comprising activating the transmitter from an authority in at least one member of a group comprising a county in which the specific area is located and a municipality in which the specific area is located.

13. A receiver for receiving a notification signal of severe weather for a specific area and a test signal, the notification signal comprising type data indicating a type of severe weather and area designation data indicating the specific area of the severe weather, the area designation data for the specific area comprising at least one member of a group consisting of sector data indicating a sector in which the severe weather is expected and city/county data indicating a city/county in which the severe weather is expected, the receiver comprising:

a timer configured to time out in a period greater than a regular interval within which the test signal is to be received, to generate a trouble alarm upon timing out, and to reset upon receiving the test signal; and

a decoder configured to decode the type data to determine the type of the severe whether, to decode the area designation data to determine if the receiver is configured to cause an alarm to be triggered for the specific area in which the severe whether is expected, and, if so configured, to cause the alarm to be triggered for the specific area indicated by the area designation data.

14. The receiver of claim 13, wherein the receiver is normally connected to an AC power source and a backup battery and can be powered down by disconnecting the AC power source and the battery.

15. The receiver of claim 13, wherein the receiver is tuned to receive the notification signal from a transmitter that is activated by an emergency warning mechanism controlled by a local authority.

16. The receiver of claim 13, wherein the receiver is tuned to receive the notification signal from a transmitter that is activated with a warning siren by an emergency warning mechanism controlled by a local authority.

17. The system of claim 16, wherein the local authority comprises an authority in at least one member of a group comprising a county in which the specific area is located and a municipality in which the specific area is located.

18. A method for triggering an alarm in response to notification, by a local authority, of severe weather in a specific area, the method comprising the steps of:

receiving the notification comprising a signal containing a system identification code, a type code, a city/county code, and a sector code;

(a) checking the received system identification code to determine whether the signal is a valid transmission;

(b) checking the received type code to determine whether the signal is a test signal or a severe weather warning;

(c) continuing with step (h) if the signal is a test signal;

(d) checking the received city/county code to determine whether the signal matches a corresponding pre-programmed code;

(e) checking the received sector code to determine whether the signal matches a corresponding pre-programmed code;

(f) generating a warning alarm if corresponding codes are found in steps (d) and (e), otherwise, ignoring the notification; and

(g) generating a trouble alarm if the test signal has not been received within a predetermined interval;

otherwise,

(h) resetting a tiner to the predetermined interval upon receiving the test signal to prevent the trouble alarm from being generated.
