ABSTRACT:
A system for detecting a moving hot bearing or wheel is provided. The system includes a summer for combining an input signal representative of radiation emitted by the moving hot rail car bearing with a feedback signal. The system also includes an integrator to accumulate an error resulting from the combination of the input signal and the feedback signal. The system further includes a feedback loop to feedback output of the integrator to the summer.
