Abstract
A method and device for rapidly predicting the temperature of an object through a sensor reading of the object's temperature by using a processor comprising finite impulse response (FIR) filters to determine the average value, the first derivative, and the second derivative of the sensed temperature based upon a predetermined number of temperature samples, apply a respective weighting factor to each of the average value, the first derivative, and the second derivative respectively, and calculate a temperature estimate by combining the weighted average value, the first derivative, and second derivative together with an offset factor.
