Opis:: The following article describes research on possibility of using pattern recognition algorithms in the optical measurement system for estimation of the blood chamber volume in the Polish Ventricular Assist Device (POLVAD). The optical system is being developed at the Department of Optoelectronics, Silesian University of Technology, Poland. Data analysis methods include a feature subset selection algorithm involving principal components analysis and objective function as quality criterion. The analysis takes into account 17 patterns reflecting particular volumes. The k-nearest neighbours method is used as pattern classifier. The pattern recognition system was initially designed for an array of gas sensors and this paper describes its further development.

Opis:: The article presents further developments of an optical system to be used in temporary blood volume measurements in the Polish ventricular assist device. The research focuses on quasi-dynamic measurements (flow rate of 5 ml/s). Characteristics of signals from selected configurations of optical transmitters and receivers are shown. A volume approximation using a PCA algorithm supported by a LRS function is introduced. Plans of further development are stated.

Opis:: The following paper introduces the problem of noninvasive pressure measurements in Polish artificial heart prosthesis. The pressure sensor is proposed and introduced, and preliminary tests are shown. The paper deals with the proposed sensing elements, requirement noninvasive solution and preliminary tests of polyurethane membrane transmission. The paper includes also experimental results of a fiber pressure sensor introducing noninvasive pressure measurements with pressure transmission through a polyurethane tube wall.
