The aim of our study was to determine whether psychological effects of sensor attachment and the awareness of the subject being measured could influence the posturographic tests performed using a force plate and combined using psychophysiological measurements (EDA, HR, respiration).

Bushings are tubular inserts that can be used for the calibration of thermometers in order to increase the thermal contact between the thermometer’s sensor and the phase boundary in the thermometer well of the cell. The effect of bushings on the self-heating and on the immersion profiles of three different thermometers was researched. Besides experimental measurements, some qualitative results of numerical modeling are also presented.

A custom-made numerical model capable of conductive and radiative heat transfer is extensively presented in the paper. It was used for modeling of heat losses in open metal freezing-point cells. Besides the modeling results, experimental results are also presented that confirm the operation of the model. The main objective of the paper is to analyze and evaluate the temperature error due to radiative heat losses in glass cell.

A novel, non-contact, optical type of surface moisture sensor was designed and investigated. It is based on absorption of NIR light absorption from laser source. Two laser sources are used, one with water-absorbing wavelength and the other which is much less affected by water and two InGaAs photo diodes. The sensor’s response was measured by a precision embedded data acquisition system NI CompactRIO and evaluated using a moisture analyser.

Clinical thermometers in intensive care units are used for the continuous measurement of body temperature. This study describes a procedure for dynamic measurement uncertainty evaluation in order to examine the requirements for clinical thermometer dynamic properties in standards and recommendations. A Monte Carlo method was implemented for dynamic measurement uncertainty evaluation. Results showed that dynamic uncertainty is much larger than steady-state uncertainty.
