EGRESS SYSTEM
First Claim
1. An egress system for use in a structure, which structure defines a plurality of possible paths of travel, said system comprising:
- a. one or more visual signs, each of said signs being located at a selected point along one or more of said paths of travel, each of said signs being configured to convey information in the form of visual communication and to convey at least two alternative messages;
b. a central processing unit; and
c. one or more sensors, each sensor being configured to detect an environmental condition and to send a signal indicative of said condition to said processing unit, wherein said processing unit is configured to determine the safest of said paths of travel based upon signals received from said sensors, and to send a processed signal to each of said signs to thereby cause said signs to convey a pre-selected one of said at least two alternative messages, thereby visually identifying at least one of the safest of said paths of travel under the condition(s) detected.

Abstract
An egress system for use in a structure which defines a plurality of paths of travel where the system comprises one or more visual signs, each visual sign being located at a selected point along one or more paths of travel and each visual sign being configured to convey information in the form of visual communication and to convey at least two alternative messages. The system further comprises a central processing unit and one or more sensors being configured to detect an environmental condition and to send a signal indicative of this condition to the central processing unit. The central processing unit is configured to determine the safest of the paths of travel based upon signals received from the sensors and to send a processed signal to each of the visual signs to thereby cause the visual signs to convey a pre-selected one of at least two alternative messages, thereby visually identifying at least one of the safest paths of travel under the condition(s) detected. Preferably, the system further comprises audible communication devices which convey messages consistent with identification of the safest paths of travel.

18. A method of providing safe exit from a structure having a plurality of possible paths of travel comprising:
-
(A) providing one or more sensors for detecting an environmental condition;
(B) sending an electronic signal indicative of said condition to a central processing unit;
(C) configuring said central processing unit to receive said electronic signal, determine the safest path of travel for exiting said structure, and transmit said processed electronic signal to one or more communication devices; and
(D) providing one or more communication devices to receive said processed signal and to convert said processed signal into visual or intelligible non-visual communication, or both.
