The invention provides a universal rate-based transducer for advancing diagnostic and predictive analyses of low frequency physical phenomena, such as associated with heat and mass transfer, solid and fluid mechanics, pressure and seismic analysis. In many applications, such as in the fire metrology, aerospace, security and defense sectors, rate information is crucial for reaching fast and reliable diagnosis and prediction. In one preferred embodiment, the invention comprises a universal voltage rate sensor interface that accurately recovers the instantaneous heating/cooling rate, dT/dt. Upon appropriate calibration, this sensor interface allows real-time extraction of rates associated with many physical quantities of interest (e. g. , temperature, heat flux, concentration, strain, stress, pressure, intensity, etc. ).

A method and system for detecting the presence of a frozen deposition at an interface between a substrate of known thermophysical properties and surroundings of unknown thermophysical properties. The system involves applying a predetermined quantity of heat to a temperature sensor positioned at the interface to cause a thermal perturbation, measuring an output signal of the sensor subsequent to applying the predetermined quantity of heat, and comparing one or more measured values of the output signal to one or more reference output level values to determine the presence or absence of the frozen deposition.
