Wyjaśnione zostały różne zagadnienia programowe oraz sprzętowe, takie jak sposób komunikacji głównego mikroprocesora z peryferiami czy automatyczna kalibracja układu pomiarowego. Głównym założeniem projektu jest to, aby budowana platforma była uniwersalna i posiadała możliwości rozbudowy. Daje to możliwości sprecyzowania wymagań sprzętowych dla urządzeń dedykowanych do konkretnych celów, które będzie można szybko wprowadzić na rynek, na którym będą konkurencyjne pod względem funkcji oraz ceny. Ważne jest, aby ze skonstruowanej płyty ewaluacyjnej mogły bez przeszkód korzystać osoby, które także działają w obszarze pomiarów BIA, lecz nie mające zaplecza elektronicznego lub informatycznego. Wymusza to stworzenie przejrzystego i prostego w obsłudze interfejsu użytkownika.

characterized by the Bioelectrical Impedance (BI). Bioimpedance measurements are used
in medicine for diagnostic purposes, including the so-called Bioelectrical Impedance
Analysis (BIA), which is a noninvasive method of body composition analysis [1-3]. This
method is increasingly popular also in sports medicine, aesthetics medicine and dietetics.
Several manufacturers offer specialized electronic equipment for professional body
composition measurements based on bioimpedance analysis [3]. However, the use of
such popular, cheap systems is rather restricted to the dedicated area, and – as a result –
in more universal studies one has to adapt the equipment to the particular purpose, which
could be difficult, or to purchase much more sophisticated system at much higher price.

The device was built as an universal evaluation board, which should aid in development of bioelectrical impedance measurement instruments that can be used in a practical, commercial field. Besides that, an analysis and review of electrical devices used in bioimpledance measurements were made (directed onto tissues, including fluids, tissue to electrode interfaces, human body in general).

However, these new features come with added complexity, and large amounts of information can overwhelm vessel crews and fleet operation centers, and the current state-of-the-art tools cannot filter out only the most important data for a given time and location. This paper presents the concepts and the algorithms of a software suite that provides a user with problem-oriented advice about a particular risk endangering a vessel and its crew. Based on the calculated navigational dangers and their predicted development, actionable guidance is proposed in an easy-to-understand human language. The quality of good seamanship is improved by a holistic approach to vessel installation, automated fleet operation center priority queuing, and the evaluation of crew performance during simulator training and daily operations. Both the software user interface, ...
