Podczas drukowania na drukarkach 3D w technologii FFF zauwa żono problem braku danych o czasie pracy i zużycia filamentów. Ciężko również oszacować wizualnie, ile zostało na szpuli filamen tu, a tym samym, czy wystarczy na dany wydruk. Dane szacunkowo podaje slicer przy generacji g-codu, jednak należałoby je ręcznie sumować. Poza tym rodzi się problem co w przypadku przerwania wydruku wtedy nawet te informacje nam nie pomogą. Precyzyjne dane pozwalają na bardziej dokładne określenie kosztów, co jest szczególnie przydatne, gdy chcemy drukować dla kogoś. Zebrane informacje przyczynią się również do szybszej diagnostyki oraz optymalizacji procesu druku.

When printing on 3D printers using FFF technology, the problem of lack of data on run time and filament consumption has been noted. It is also difficult to visually estimate how much filament is left on a spool, and thus whether there is enough for a given print. The data is estimated by the slicer at g-code generation, but it would have to be added up manually. In addition, there is the problem of what if the print is interrupted then even this information will not help us. Precise data allows us to determine the cost more accurately, which is especially useful if we want to print for someone. The collected information will also contribute to faster diagnostics and optimization of the printing process.

Assigning transported material with a supplementary information is becoming relevant for the needs of improving the efficiency of industrial processes. In the mining industry annotating the mined ore could bring benefits due to expected decrease of the processing energy consumption and increase of productivity. DISIRE project was focused on the implementation of e-pellets for various raw material processing and transportation processes. The paper presents laboratory tests of altern ative RFID equipment for annotating ore with marked tags. Several aspects of tags traceability were investigated for the needs of the industrial tests that were eventually done in the underground mine environment. The laboratory tests results were compared with the similar tests described in the literature, that were done in the different conditions.

This paper introduces a solution to a design problem caused by necessity of electromagnetic noise reduction in simple close-range wireless command and control systems, including Radio-frequency identification (RFID) systems. Trade-off between simplicity of data transmission, detection and decoding on one side vs. presence of high frequency harmonics in transmitted signals on the other makes some designers choose approach in which trapezoidal waveforms are used instead of rectangular ones. Moreover, edges of trapezoidal waveforms are additionally rounded to further limit presence of higher harmonics and thus to comply to EMI regulations and requirements. The paper proposes a solution based on a reimplementation of a high-voltage structure already proposed by the author, but implemented with use of different semiconductor technology process. Utilization of this new process and devices available in this technology makes possible significant increase of the circuit operation quality.
