Abstract

There is provided an apparatus and method for measuring a thermal property of a medium under study, comprising at least two temperature sensing elements 120a and 120b and a material 110 of known thermal properties sandwiched between the at least two temperature sensing elements. A processing unit 200 is arranged to provide an adaptive filter to adaptively filter the outputs of the at least two temperature sensing elements to provide an indication of the thermal properties of the medium under study. The material may be an insulator and together with the sensing elements forms a compound sensor 100 such as may measure the relative temperature of the respective elements. The adaptive filter may be one of Least Mean Square, Wiener or Kalman filtering. An application of the sensor is detecting the fill level of a bladder by detecting a change in the temperature of an abdomen adjacent to the bladder.
