Traffic detection and signal system and method therefor
First Claim
1. A traffic detection and signal system for pathways within an industrial work environment comprising:
- at least one sensor positioned to detect objects approaching a pathway intersection within an industrial work environment;
at least one visual indicator electronically linked to said at least one sensor to visually indicate that an object is approaching a pathway intersection from another direction; and
a controller electronically coupled to said at least one sensor and said at least one visual indicator to receive a signal from said at least one sensor that an object is approaching a pathway intersection and to transmit a signal to activate said at least one visual indicator.

Abstract
A traffic detection and signal system for pathways within an industrial work environment and method therefor includes at least one sensor positioned to detect objects approaching a pathway intersection and at least one visual indicator electronically linked to the at least one sensor to visually indicate that an object is approaching. The system further includes a controller electronically coupled to the at least one sensor and visual indicator to receive a signal that an object is approaching a pathway intersection and transmit a signal to energize the at least one visual indicator.

-
a plurality of sensors positioned to detect objects approaching a pathway intersection within an industrial work environment;
a plurality of visual indicators electronically linked to said sensors to visually indicate that an object is approaching a pathway intersection from another direction; and

19. A method for detecting and signaling movement along pathways within an industrial work environment, said method comprising the steps of:
-
sensing for objects approaching a pathway intersection within a predetermined sensing range;
detecting an object approaching a pathway intersection within a predetermined detection field;
receiving a signal from at least one sensor positioned toward a first direction;
transmitting a signal from the controller to activate at least one visual indicator positioned toward all directions but the first direction until the object is no longer approaching the pathway intersection; and
energizing the at least one visual indicator to provide visual indication in all directions but the first direction until the object is no longer approaching the pathway intersection. - View Dependent Claims (20, 21)
