Abstract

See full text

Information as to a direction(s) to be followed to avoid a hazard is unambiguously transmitted by energizing lamps of an array in accordance with stored data whereby unique sequential flash patterns are generated. A selectable pattern includes a long initial flash followed by a plurality of relatively short flashes which progress in stepwise fashion in the direction of desired observer motion, the pattern ending with a terminal lamp of the array being flashed repetitively. The pattern is then caused to repeat after an off time which is of long duration relative to at least the short flashes of the pattern.
