Electronic clinical thermometer

Claim 1

An electronic clinical thermometer comprising: temperature sensing means for sensing body temperature at a prescribed part of a body; predicting arithmetic means for predicting a final, stable temperature based on the sensed body temperature; arithmetic means for calculating a difference value between the sensed body temperature and the predicted final, stable temperature; memory means for storing a weighting function, in which elapsed measurement time is a variable, prescribing a change in weighting applied to the difference value; weighting means coupled to the memory means and a control means for obtaining a set of display temperatures for a plurality of sampling instants each of which display temperatures is derived by selecting a weight based on the weighing function and the elapsed time at a sampling instant, applying the selected weight to the difference value, and adding the weighted difference value to the sensed body temperature; said control means clocks elapsed measurement time for controllng said temperature sensing means and said weighting means at said plurality of sampling instants; and display means for displaying the obtained set of display temperatures.
