    Opis:
    The article presents a description of sitting posture monitoring system, built on Raspberry_Pi_3b, Tact Switch buttons, a prototype board and a rubber mat. RaspberryPi connected to the sensors communicated with a personal computer. This allows on the one hand to immediately inform the seated about the appearance of no symmetry of the position on the chair and managing the time of sitting and breaks on the other. The proposed system ensures identification of the degree of incorrect seating during work and gives the opportunity to improve the user's posture, which affects many topics related to health and work efficiency. System possesses a graphical user interface. During system operation, monitoring data is collected and can be used for further research towards an optimal impact on the user to get rid of the faulty sitting habits.

    Opis:
    In this article, a Low-cost measurement Infra-Red (IR) system for dynamic thermal testing of electronic devices is described. The element is powered by a step-function current and simultaneously temperature is measured by a fast single-detector IR head. The thermal impedance Zth(jω) is calculated using the Laplace transform and the Foster network is to get thermal time constants distribution.

    Opis:
    In this paper authors present application of deep neural networks for super-resolution interpolation of infrared images. A residual neural network with reduced number of layers was used. The transfer learning using RGB visual images was applied in this research. The validation of the network was performed for 32×24 and 160×120 pixels infrared images, with the up-sampling scale factors 2, 3, 4, 5 and 6. Monitoring of high temperature industrial processes like inductive heating and thermal hardening is the main application of proposed methods.

    Opis:
    This paper demonstrates the application of different image processing techniques to process high resolution visual images and merge it with low resolution thermograms to improve its level of detail. The same idea is applied in commercially available thermal cameras (e.g. FLIR with MSX® technology). Low resolution thermograms considered in this paper were obtained from a thermal scanner with point infrared detector (Fig. 1) sensitive to long wavelength infrared spectral range. The proposed algorithms are Laplacian, Sobel operator, embossing and Gaussian differential blur (described in section 3). The authors processed 6 different thermograms to qualitatively assess obtained results. It was done in a statistical manner through a survey and revealed that both Sobel operator and embossing provided the most clear, detailed and unambiguous results (Fig. 5). Such algorithms may be applied for processing more channels in a multispectral, cost-effective system.

    Opis:
    The paper presents a part of a prototype system for the monitoring of selected vital functions of humans and some preliminary results obtained from the device using implemented algorithm. The system consists of such essential modules like a microcontroller board, an inertial measurement unit and additional sensors. The main task of the device is human movement monitoring and detecting selected anomalies, e.g. fall or fainting. At the first stage, the movement classification was considered. The main movement type are walking, running and selected variants of transitions between different phases like standing up or going downstairs. The determining of the movement is based on the intuitive algorithm using raw data from accelerometers complemented by sensors like barometer and heart rate monitor. The algorithm utilizes automated multiscale-based peak detection and wavelet transform energy calculations. Finally, some further work directions and development possibilities are discussed.
