Abstract
Abstract Disclosed is a method and a system for conveying alarm information wherein a visual alarm signal is transmitted from a first location in response to the occurrence of a preselected event thereabout. A preselected observer at a different location observes the visual alarm signal and relays notice of the receipt of the signal to proper authorities for response. A plurality of transmitters is utilized, each at a different location, and each transmitter encodes its signal with information indicating its location and further information indicative of which one of a group of preselected events has occurred. The observer, upon visually observing a signal, focuses a receiving device on the source of the signal. The receiving device decodes the signal to extract the coded information therefrom and furthermore rejects improperly coded or noncoded signals.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
114 words
A method for conveying alarm information comprising the steps of: providing high intensity omni-directional visual alarm signal generating devices in a plurality of different alarm locations; activating said signal generating means to produce an omnidirectional visual alarm signal at a first location of said plurality in response to a preselected event; encoding said visual alarm signal to indicate the position of said first location; positioning in a receiver location remote from said plurality of alarm locations a directional receiver for producing an encoded electrical output signal representing said encoded visual alarm signal; directing said directional receiver at said first location; and decoding said electrical output signal to determine the position of said first location.
Claim 2
Independent Claim
114 words
A method for conveying alarm information comprising the steps of: providing high intensity omni-directional visual alarm signal generating devices in a plurality of different alarm locations; activating said signal generating means to produce an omnidirectional visual alarm signal at a first location of said plurality in response to a preselected event; encoding said visual alarm signal to indicate the position of said first location; positioning in a receiver location remote from said plurality of alarm locations a directional receiver for producing an encoded electrical output signal representing said encoded visual alarm signal; directing said directional receiver at said first location; and decoding said electrical output signal to determine the position of said first location.
