Patent Number:	7332878
Title:	Electric Candle Flame Simulator
Abstract:	A method, apparatus and system for electrical simulation of a flame that provides for the projection of light that is a mixture of at least two colors. At least one of the two colors of light is projected over time according to a complex light intensity pattern. The complex light intensity pattern is constructed via an aggregation (superimposition) of a plurality of independent intensity transition signals. Each intensity transition signal represents a separate and varying intensity pattern. The complex light intensity pattern creates a perceptually real and pleasing visual effect upon the human eye, much like that created by the flickering of a real combustion flame and employs other than random or pseudo random intensity patterns.
