Abstract
Abstract A public warning system for alerting the public of natural disasters, such as tornadoes and other severe atmospheric disturbances, and having capabilities of giving general warning for civil defense for other emergencies. The system also has the capability to act as a sensor grid to obtain scientific atmospheric or weather or other geophysical data. A unique grid detection system is provided that predetermines and selects the area that will be affected and which residential areas will lie in the path of an approaching tornado. A selective warning of the affected residents is provided by sensor transmitters located in the grid at spaced grid points along the prevailing tornado''s track and to some safe distance along each side of the trace by signaling individual receiver alarm devices. The automatic alarm network is self-sustaining and is not dependent upon existing power distribution systems for its actuation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
110 words
An atmospheric disturbance warning system for detecting an approaching atmospheric disturbance comprising atmospheric condition sensors and transmitters responsive to said sensors which are located in a grid pattern, said transmitters transmitting an alarm signal by radio frequency to a receiver which detects the radio frequency signal and activates an alarm, said transmitter providing the signals for activating adjacent grid track monitors and home alarm receivers, the transmitter modulations being used to provide alarm signals through a first circuit to transmit signals in the path of the approaching disturbance termed mode (1) and a second circuit to transmit signals in and across the path of the approaching disturbance termed mode (2).
Claim 2
Dependent Claim
110 words
An atmospheric disturbance warning system for detecting an approaching atmospheric disturbance comprising atmospheric condition sensors and transmitters responsive to said sensors which are located in a grid pattern, said transmitters transmitting an alarm signal by radio frequency to a receiver which detects the radio frequency signal and activates an alarm, said transmitter providing the signals for activating adjacent grid track monitors and home alarm receivers, the transmitter modulations being used to provide alarm signals through a first circuit to transmit signals in the path of the approaching disturbance termed mode (1) and a second circuit to transmit signals in and across the path of the approaching disturbance termed mode (2).
Claim 3
Dependent Claim
50 words
ThE warning system as described in Claim 1 comprised of a logic section with a set of gates that determine the manner of transmission by selecting from the first circuit termed mode (1) storm present (storm activated) and the second circuit termed mode (2) storm alert present (radio frequency activated).
Claim 4
Dependent Claim
29 words
The logic section as described in claim 4 whereunder the mode (1) storm present (storm activated) condition, the transmitter will broadcast downline and crossline alarm signals to adjacent monitors.
Claim 5
Dependent Claim
31 words
The logic section as described in claim 4 whereunder mode (2) storm alert present (radio frequency activated) conditions the adjacent monitors will receive the transmitted alert and retransmit it down line.
Claim 6
Dependent Claim
42 words
The warning system of claim 1 in which the sensors and transmitters have the capability of providing a selection of radio frequency signals derived from frequency modulated carrier to alert home and other alarm receivers along the path of an approaching storm.
Claim 7
Dependent Claim
50 words
The warning system as described in claim 5 in which the said receiver alarm is self sustaining through a trickle charge to recharge batteries and consists of a logic control and an alarm generator, the said receiver section detecting the monitor alert signals and converting them into audio level signals.
Claim 8
Dependent Claim
59 words
The warning system of claim 1 in which the receiver section is made up of a radio frequency preamplifier, an intermediate frequency conversion strip and an audio signal detector, and the audio signal is then passed from the detector through a filter network which is tuned to output two separate coded audio alert signals into a logic ''''and'''' gate.
Claim 9
Dependent Claim
54 words
The receiver alarm as described in claim 7 in which when the two signals are present the ''''and'''' gate outputs a discrete to turn on an alarm generator, the alarm discrete also triggering a time delay latching circuit that maintains the alarm discrete for a finite time after the alert condition has been passed.
Claim 10
Dependent Claim
98 words
An atmospheric disturbance warning system for detecting an approaching atmospheric disturbance comprising atmospheric condition sensors and transmitters responsive to said sensors which are located in a grid pattern, said transmitters transmitting an alarm signal by radio frequency to a receiver which detects the radio frequency signal and activates an alarm, said alarm signals being transmitted in accordance with grid actuation logic which covers three parallel tracks centered at the initial detection point, said tracks paralleling the known local storm paths for the area, and adjacent parallel track monitors alerted by selected frequencies of the initial sensor transmitter monitor.
Claim 11
Dependent Claim
98 words
An atmospheric disturbance warning system for detecting an approaching atmospheric disturbance comprising atmospheric condition sensors and transmitters responsive to said sensors which are located in a grid pattern, said transmitters transmitting an alarm signal by radio frequency to a receiver which detects the radio frequency signal and activates an alarm, said alarm signals being transmitted in accordance with grid actuation logic which covers three parallel tracks centered at the initial detection point, said tracks paralleling the known local storm paths for the area, and adjacent parallel track monitors alerted by selected frequencies of the initial sensor transmitter monitor.
