  - FLUCTUATION AND NOISE LETTERS - Rok 2006

  The results of noise measurements in low frequency range for CNY 17 type optocouplers are presented. The research were carried out on devices with different values of Current Transfer Ratio (CTR). The methods for identification of Random Telegraph Signal (RTS) in noise signal of optocouplers were proposed. It was found that the Noise Scattering Pattern method (NSP method) enables to identify RTS noise as non-Gaussian component...

  - OPTO-ELECTRONICS REVIEW - Rok 2009

  In the paper, a method of estimation of parameters of Gaussian and non-Gaussian components in the noise signal of semiconductor devices in a frequency domain is proposed. The method is based on composing estimators of two spectra, corresponding to noise (Gaussian component) and two-level RTS noise (non-Gaussian component). The proposed method can be applied for precise evaluation of the corner RTS frequency fRTS in the noise...

  - Bulletin of the Polish Academy of Sciences-Technical Sciences - Rok 2008

  The course of design of an optocoupler's PSpice macromodel including noise sources is described. The PSpice macromodel is proposed for the low frequency range. The PSpice model of a MOSFET transistor was applied as the noise source type 1/(f^alfa) in an optocoupler PSpice macromodel. In the enhanced macromodel the value of an exponent α can be changed in the range of 0.8 - 1.25.

  - Polish Maritime Research - Rok 2006

  W artykule przedstawiono założenia projektowe i koncepcję rozwiązania konstrukcyjnego oraz napędu i sterowania urządzenia sprzęgającego pchacz i barkę dwusegmentowego statku śródlądowego i przybrzeżnego. Zaprezentowane urządzenie umożliwia zarówno sztywne połączenie, jak i wzajemne kontrolowane wychylanie obu segmentów względem siebie, co w znacznym stopni zwiększa manewrowość, a tym samym bezpieczeństwo żeglugi, zwłaszcza na wąskich...

  - Rok 2015

  An optoelectronic system for measurements of hematocrit level (HCT) in the whole human blood is presented. Proposed system integrates a dedicated optoelectronic sensor, a microcontroller and a small LCD display in a low cost, battery-powered, handheld device. Chosen method for determining blood hematocrit level is based on optical properties of whole blood in visible and NIR wavelength range. Measurements with the use of proposed...

  This article describes the device which may be used to generate false GPS signals and emit them into radio communication channel. Such attack is called GPS spoofing. Each GPS receiver which remains in the range of a spoofing device (called spoofer) indicates time and position coordinates which are predetermined by the spoofer’s operator. Spoofing may be used e.g. in order to disable the terrorist group from obtaining correct navigation...

  - Rok 2021

  As access to space conditions becomes more available, both technically and economically, scientists’ interest in launching finer and more sophisticated experiments grows. To be qualified for launch, such experiments need to be carefully tested prior to the event. The tests should represent actual launch conditions as closely and in a detailed manner. Typical tests for payload include: vibration tests, thermal and vacuum tests,...
