Abstract
A system for detecting a change in medium sensed by a thermistor comprises a first module that receives a temperature signal from a thermistor and that calculates a first dissipation factor of the thermistor. A second module receives the first dissipation factor of the thermistor and detects at least one of an unexpected medium and a change in medium based on the first dissipation factor.
