  • System of breath collection and analysis for diseases detection

    Collection and study of composition of the exhaled air is now intensively investigated to develop non-invasive medical diagnostics based on presence of metabolic compounds in the exhaled air. The process of collecting and processing of the exhaled air must fulfill relevant conditions to achieve satisfactory results. The paper presents the system of collecting samples of exhaled breath and the proposed methods of its analysis, using...

  • The low coherence Fabry-Pérot interferometer with diamond and ZnO layers
    Publication

    The authors present a fiber-optic Fabry-Pérot interferometer built with the application of diamond and zinc oxide (ZnO) thin layers. Thin ZnO films were deposited on the tip of a standard telecommunication single-mode optical fiber (SMF- 28) while the diamond layer was grown on the plate of silicon substrate. Investigated ZnO layers were fabricated by atomic layer deposition (ALD) and the diamond films were deposited using Microwave...

  • The measurement of input power of power supply in network disturbed by low frequency distortions

    In the paper authors present results of observation of input power changes versus harmonics amplitude in supply voltage of low-power power supply device. In the study, the electrical measurements supported with thermal imaging were used. The input circuit elements of studied device responsible for input power increase are pointed

    - Year 2016

    In the paper the investigation results using thermal imaging methods are presented. The examined is a state of equipment under test and its protecting components. The estimations are done for the chosen protecting elements during surge immunity testing. The results show that the thermal imaging methods are useful for early detection of possible damage of a device being tested

  • Use of optical skin phantoms for calibration of dermatological lasers

    A wide range of dermatological diseases can be efficiently treated using laser heating. Nevertheless, before the new laser is introduced into clinical practice, its parameters and ability to interact with human skin have to be carefully examined. In order to do that optical skin phantoms can be used. Such phantoms closely imitate the scattering and absorption properties of real human skin tissue along with its thermal properties,...

    - IEEE SENSORS JOURNAL - Year 2016

    WO3-based gas sensors were investigated under UV-light irradiation and at different working temperatures with the object of achieving superior sensitivity and selectivity. Resistance fluctuations in the WO3 layer were studied together with dc resistance measurements. The data were taken in synthetic air, ethanol, nitrogen dioxide, and mixtures of these gases. We conclude that UV irradiation can easily be applied to enhance the...

    - Metrology and Measurement Systems - Year 2016

    Electronic Double-Layer Capacitors (EDLC), called Supercapacitors (SC), are electronic devices that are capable to store a relatively high amount of energy in a small volume comparing to other types of capacitors. They are composed of an activated carbon layer and electrolyte solution. The charge is stored on electrodes, forming the Helmholtz layer, and in electrolyte. The capacitance of supercapacitor is voltage- dependent. We...

  • Zabezpieczanie transmisji w rozproszonym systemie pomiarowym z wykorzystaniem algorytmu XXTEA
    Publication

    - Year 2016

    Artykuł dotyczy bezpieczeństwa transmisji danych w bezprzewodowym systemie pomiarowo-sterującym. Dokonano przeglądu algorytmów szyfrowania ze szczególnym uwzględnieniem tych dedykowanych do jednostek o niewielkiej mocy obliczeniowej. Moduły pomiarowe przesyłają bezprzewodowo do centrali systemu dane zabezpieczone zmodyfikowanym algorytmem XXTEA.
