ABSTRACT:
Circuitry for using the statistical properties of detected radiation in the time domain to discriminate between stimuli from fire and non-fire sources. Statistical discriminators for fire sensing may be combined with other types of sensors operating in the frequency domain for developing improved sensitivity with better security against false alarms. Such other types of sensors may include peak detectors, zero crossing detectors, second derivative-equal-to-zero detectors, for example. The invention determines the mean or average, the variance or standard deviation, the mean deviation, and the Kurtosis of sampled data in statistical analysis to discriminate between fires and non-fires.
