In the article the development, operation principles and interface of the cross-platform mobile application for the neuro-electrostimulator ‘SYMPATHOCOR-01’ were described. The developed application makes possible to remotely control the device using Bluetooth Low Energy technology. The advantages of the application were compared with the native application based on Android. It was shown that memory footprint has decreased 3-fold, source lines of program code has decreased by 2.5 times, the number of potential user has increased by 1.5 times, minimal RAM usage increased 4-fold, the maximal usage of RAM increased by 20 MB, minimal CPU usage increased 5-fold, maximal CPU usage increased by 14%. The application interface copies the interface of the ‘SYMPATHOCOR-01’ device from 1997, which ensures legacy of the mobile application interface.

Complex postural loads have a significant effect on all systems of the human body. Such movements in space create unique conditions for the correction of his hemodynamics. Special technical means are required to ensure reliable registration of physiological parameters. The aim of the work was the development of such a multi-channel device with high accuracy of analog to digital signal conversion and wireless data transmission. To develop the device, methods of automatic control and digital signal processing were used. Schemes of adaptive amplification of signals with automatic choice of a working point have been developed. The device is implemented on the basis of a modern electronic base using fast ADCs (1000 kbps), microcontrollers (32 bits) and Bluetooth modules (4th generation). The tests that confirmed the declared characteristics were carried out. Also, the developed device was used in a complex study of the neuro-systemic reactions of the human body to complex postural loads.

The values of Brillouin frequency shifts for various types of optical fibers at room temperature and without longitudinal tensile force are analyzed in this work. The results of experimental examinations of optical fiber characteristics which were exposed to external influences are shown. The program for automatic determination of fiber type by re-flectogram is presented. The database of profiles of the Mandelstam — Brillouin backscatter spectrums for fibers of different kinds and manufacturers allow to classify the optical fibers in the optical cables and detect damaged sections of fiber optical communication line. The work was performed with the financial support of the Ministry of Education and Science of the Russian Federation within the scope of the base part of a State Assignment within the sphere of scientific activity (Project No. 8.9334.2017/8.9).

The paper deal with a new measurement method for rotation speed and movements of shafts using non-contact eddy current sensors. The main advantages and shortcomings of this method are considered. The prospects of use of this method for various practical applications are analyzed. Special attention in the work is paid to errors of measurements that arise during the using of this technique and resistance of this method to impact of noise. Possible paths for improvement of characteristics of this method are presented. Now proposed method assumes determination of rotation speed with inaccuracy about 0.1 RPM and the space provision of a shaft with inaccuracy of 0.1 mm when using only one sensor.

The paper deal with a problem of the effective frequency estimator of signals development, particularly, beat signals of FMCW radar systems. The described problem is actual in many short range radar applications such as the level or distance measurement. The proposed estimator is based on the approximation of the correlation function argument in time domain by the generalized least square method with the weighting that takes into account the influence of additive and multiplicative interferences in the case of high signal to noise (SNR) and signal to interferences (SIR) ratios. The obtained estimator has the properties that are near to the properties of the Maximum likelihood method and has much less computation complexity then traditionally used techniques, such as periodogram based estimators.

Zirconia nanotubular layer with an outer tube diameter « 25 nm was synthesized by potentiostatic anodization. The Zr/ZrO2-NT/Au memristive structure is fabricated using stencil mask and magnetron sputtering techniques. Current-voltage characteristics are measured in full cycles of resistive switching with varying parameters of the applied harmonic voltage. An equivalent circuit with unidirectional electrical conductivity for the studied structure is proposed. Estimates of the electrical resistance of memristors in high- and intermediate resistivity states are performed. The high synaptic plasticity of memristors based on the Zr/ZrO2-NT/Au structure is shown.

The electrical bio-impedance signal obtained from brachial artery can be used to determine the arterial blood pressure. This paper proposed a novel approach of brachial artery projection on skin surface. The method based on electrical impedance measurement in relation to the change of blood flow during cardiac cycle. Appropriate parameters of multichannel electrode system have been designed to achieve the sensitivity to brachial artery pulsation. The results of multichannel upper arm mapping had shown the possibility of brachial artery projection. The obtained signal which corresponds to brachial artery can allow the measurement of diameter waveform.
