    • A system is disclosed that essentially eliminates the delay in measurement of temperature by a sensor due to exponential response of the sensor. The system finds the rate of change of the sensor signal, multiplies it by the time constant of the sensor signal and adds the result to the instantaneous value of the sensor signal to predict the final value of the sensor signal or the actual value of the temperature. When the sensor is permanently attached to an object, the final temperature of the object is predicted in a similar manner using the combined time constant value of the sensor and the object. The system can be software, analog hardware or digital hardware. The system also allows more accurate temperature control without undershoot or overshoot by providing a control signal proportional to the difference between a desired value and the predicted final value of the sensor signal. The system similarly eliminates the time delay in measurement and control of flow in thermal flow meters.

    • An electronic clinical thermometer has one of two temperature measuring devices each for measuring a live body temperature. A temperature estimating device estimates an equilibrium body temperature from a first data item related to change in temperature measured by the temperature measuring device during an initial period within a specified time such as about 20 seconds from the start of a measurement and a second data item related to change in temperature measured by the temperature measuring device after the initial period. If two temperature measuring devices are used, the first data item may related to the difference between temperatures measured by these two temperature measuring devices and the second data item may related to the time-rate of change in temperature measured by either of the two temperature measuring devices. The first data item may be a value obtained from the linear relationship between the temperature value measured by either of the two temperature measuring devices and the difference between them.
