The problem of creation of the automated information-measuring system of remote monitoring of human functional state of the operator on the basis of use of the method photoplethysmography.

The possibility of using the least square method for calibration of cameras in non-contact spatiol measuring systems has been studies.

This article discusses the possibility of precision measurement tools of linear and angular measurement based on photovoltaic extreme countable - interpolation system, which functional diagram allows the use of barcodes, bitmap, holographic, diffraction and interference measures.

Found that the optimum temperature for soldering contact must be considered as the temperature of the soldering rod to its diameter, length, soldering, and the thickness of the protective coating, the thermal conductivity of the material of the protective coating.

А method of weak magnetic fields measurement by nutation nuclear-magnetic teslameter on the flowing fluid is considered. The technical requirements for different construction elements of teslameter and flowing liquid medium parameters were determined experimentally and theoretically. The studies of prospective operating liquid medium have been carried out. The teslameter measuring probe was tested in pure water. The further directions of instrument modernization and accuracy characteristics improvement were determined.
