Digital stochastic measurement methods were developed in the past, with the focus onto “measurement over interval” strategy and use of stochastic dither signals. These methods obtained the increase of effective precision from low-precission A/D converters. Combination of simple analog hardware and state-of-art digital modules makes these methods suitable in many applications.Development of 4th industrial revolution (often named as Industry 4.0 concept) is extensivelly based on communication technologies advancement. This advancement enhanced microprocessor and integrated circuits based technology capabilities. The concept of digital stochastic measurement has many advantages which can be applied in Industry 4.0 concept.

In this article, the methods of measuring the relative phase difference between two simple periodic signals, based on timer modules, are considered, with an analysis of a measurement system, its following problems, and proposed solutions. The basic motivation for this research is the necessity for a very precise and accurate measurement of the relative phase difference between the voltage signal and current signal of a two-channel source, when there is a degradation of the phase in the output stage of a twochannel source. To compensate for the deviation of the measured and real phase angle of voltage and current at the output of a two-channel source, phase measurement can be realized with timer modules. This approach requires the conversion of relatively high voltage and current into periodic pulse (rectangular) waves compatible with working with timer modules, and this conversion is achieved by utilizing comparators. Although the timer approach gives excellent results in measuring time intervals, they are rarely applied in phase measurement due to several important problems that appear during the conversion of analog signals into digital signals - the impact of analog noise, an offset of the comparators, as well as asymmetric low-pass filters intended for noise reduction.

In this paper, the technology and design of a driving assistant called the Surround View Monitor (SVM) are discussed. The procedures used to create a unified, bird's-eye view are presented, which involve stitching images captured by strategically placed cameras on the vehicle. The proposed algorithm was successfully implemented on a car model and involves various stages, including camera calibration, photometric and perspective correction, scale planar transformation, and final image stitching. The paper should be considered student work and it is positioned as the foundation for the authors' future scientific work in the field of automated parking systems.

In this paper the accuracy of the power system frequency measurement achieved by means of two commonly used electronic instruments, which are a universal counter and a bench top digital multimeter, are investigated under steady-state conditions in the case of synthetized and real-life power system signals. Moreover, the accuracy of the Rate-Of-Change Of Frequency (ROCOF) estimates achieved by means of the frequency measurements is analyzed. The results obtained by both instruments are compared with each other. In addition, from the achieved measurements some remarks are drawn.

A 10 V DC quantum voltage calibration system, based on a programmable Josephson voltage standard (PJVS) operating in liquid helium, has been recently set-up and tested at INRiM. The PJVS system is partly-commercial and is based on a 10 V superconductor-normal metal-superconductor (SNS) array of 69631 Josephson junctions operated on the first Shapiro steps. The goal is to establish a new highreliability quantum voltage standard for the DC calibration of solid-state voltage sources and digital voltmeters (DVMs). The paper reports the PJVS system description and first experimental testings and calibrations, preparatory to the future participation to international comparisons as final validation of the novel system.
