Abstract: A predictive-type electronic clinical thermometer comprises a temperature sensing unit, a measuring unit for measuring elapsed time from the start of measurement and an arithmetic unit. The arithmetic unit performs a predictive operation in order to obtain a corrective value utilizing one selected prediction function at one time from among a plurality of prediction functions in which elapsed measurement time is a variable, each function defining a temperature change up to a final temperature. The arithmetic unit calculates the equilibrium temperature based upon the obtained corrective value and the sensed body temperature. In a case where an unstable temperature rise curve exhibits a transition not covered by the group of standard curves which are defined by the predictive functions, the prediction operation is suspended immediately and the actually measured temperature value is displayed at such time.

The selected data group can be changed based on change of the detected temperature in a predetermined period after the selection of data group. Further, reliability of the measurement is judged based on the detected or predicted temperature and the predicted value can be corrected if the reliability is insufficient.

Abstract: A method for determining the properties of a medium by activating temperature changing means to change the temperature of the medium from a first unperturbed temperature to a second different temperature during a first time period and permitting the temperature to relax to a final unperturbed temperature during a second time period. In a particular embodiment, for example, the intrinsic thermal conductivity and diffusivity of the medium are calculated during a selected portion of the first time period assuming an arbitrary value for the perfusion, and the perfusion of the medium is calculated during a selected portion of the second time period using the calculated intrinsic thermal conductivity and diffusivity. The calculated perfusion is then used to recalculate the intrinsic thermal conductivity and diffusivity during the selected portion of the first time period and the perfusion is then recalculated using such recalculated intrinsic thermal conductivity and diffusivity.

Abstract: A predicting-type electronic clinical thermometer in which displayed temperature rapidly attains an equilibrium temperature before the temperature actually sensed does. The thermometer stores a weighting function, in which elapsed measurement time is a variable, prescribing a predetermined change in weighting. When temperature is being sensed, weighting based on the weighting function is applied to a difference value between the sensed body temperature and a predicted value of equilibrium temperature obtained based on the sensed body temperature. The temperature displayed is caused to make a smooth transition from the start of temperature detection to the final equilibrium temperature by adding the weighted difference value to the sensed temperature.

Abstract: A density measurement instrument measures the density of a fluid by determining the frequency of oscillation of a vibrating tube filled with the fluid. An electronic excilation system vibrates the tube and the frequency of oscillation is representative of the density and the temperature. The frequency is accurately measured. A temperature control system controls the temperature of the fluid during oscillation by comparing a single temperature set point with the measured temperature of the sample. Based on this comparison, current in a first direction or in a second direction is applied to a Peltier element for heating or cooling the sample. Substantially continuous temperature readings and adjustments of the current are thus provided. The temperature information may be applied to an external data link or to a display.

Abstract: A compensation circuit for sensor lag uses a sensor temperature signal modification circuit to provide a modified sensor temperature signal for subsequent use in controlling the sensed temperature. The compensation circuit digitally compares a current sensor temperature representative signal and a sensor temperature signal at a last or preceeding sample time to produce a difference signal which is converted to a sensor slope signal and is multiplied by a sensor time constant. The resulting signal is passed through a filter to eliminate transient effects and is summed with the original sensor temperature signal to provide a sensed temperature signal for control of the temperature whereby the sensed temperature is a better estimate of the actual environmental temperature controlled by a thermostat utilizing the sensed temperature signal.
