The use of flexible wearable electronics in robotics, industry, agriculture, clothing, medicine, etc. is caused by an ever-increasing need. Various sensors and devices for reading and transmitting information based on environmentally friendly, flexible and durable materials can be securely mounted in the shell structure of the robot or attached to the surface of human skin, which will allow extracting and analyze a number of important technical and medical indicators. Important parameters include temperature, pressure, load values, air composition, environmental parameters, medical indicators, etc. The paper proposes an approach to describing the types of wearable electronics for monitoring information about the state of robotic objects involved in production, or a person, about his health, environmental monitoring, pressure sensors, various types of deformation, force sensors that can be combined with temperature sensors, physiological and biochemical sensors, and can also be included in multifunctional sensors. A network of sensors is necessary to determine the parameters of the shell structure during its operation, to monitor the state of a robot or a person. The technical parameters of the multilayer protective shell can be local values of the distributed load on the shell, pressure, tensile or bending deformation, etc. The general principles of operation of sensors and transmitters embedded in a flexible multilayer protective shell structure are considered, and structural innovations are also proposed. The paper considers functional modules that will make wearable electronics more adequate to real technical objects and for humans. A number of problems that arise in the development of wearable electronics and its application for modeling flexible intelligent shell structures are described.

This paper considers the frequency dependences of the S-parameters for printed circuit boards with modal reservation before and after the open circuit failure. Two board prototypes (with modal reservation before and after failure) were designed to experimentally study their features. The frequency dependences of S-parameters were obtained for both of them at different temperatures. It was revealed that the level of transmission ratio for the board with modal reservation before and after failure is almost the same and the effect of MR will remain after failure without affecting the useful signal except at high temperature. Moreover, all S-parameters of the prototypes decrease with increasing the temperature and increase with decreasing the temperature compared to the results obtained at the room temperature over the entire frequency range except for the resonance frequencies. This study confirms that the radioelectronic devices which use the modal reservation layout and tracing approach can work under almost any climatic conditions even after failure which in turn will improve their reliability and immunity against any interference. However, the useful signal frequency range can be decreased considerably, which must be controlled.

We evaluated the induced electromagnetic interference (EMI) on a monopole and a microstrip line (MSL) generated by an electrostatic discharge (ESD) source in a small-sized TEM-cell. Analytical, quasi-static, and electrodynamic models are presented for calculating the waveforms and amplitudes of currents and voltages induced on the monopole and the MSL. These waveforms are presented for analytical, quasi-static, electrodynamic calculations, and measurements. The maximum deviations of analytical and electrodynamic calculations results for the monopole and the MSL are 25% and 9%. An approach is presented for using half of the coaxial chamber as a matching device between the ESD source and the TEM-cell. The results of calculations and measurements agree well, which indicates the possibility of using a small-sized TEM-cell and half of the coaxial chamber. These devices could be helpful to study the effect of ESD-generated EMI on integrated circuits (IC), electronic component base, and small devices in general.

A wireless communication systems are gradually replacing cable connections in telemetry systems where possible. Often wireless communication technologies are used to collect data from objects scattered in the area. A key task in the design of communication systems is to estimate the maximum coverage area. The article compares the most popular short-range wireless technologies SigFox, LoRa, and Strizh. LoRa-based devices were selected as a result of a characteristics analysis. Data transmission range studies were carried out in mixed forest conditions, since the final device will be placed in a wooded area. During the experiments, the most optimal settings of the radio modules were selected. At the end of the article, the results of measuring the communication range are given. The data obtained can be used in the design of wireless networks in a wooded area near the city of Tomsk.

The paper presents the experimental study that proves the possibility of an ultrashort pulse (USP) decomposition into a sequence of pulses of smaller amplitude in a modal filter (MF) on a double-sided printed circuit board (PCB) without an upper reference conductor. The cross section parameters of the filter were optimized to manufacture a laboratory model. The results of modeling the effect of t (foil thickness), s (conductor separation), and w 1 (width of active and passive conductors) on the decomposed pulse amplitudes are shown in more detail. More specifically, they demonstrate that for given values of t and s, there is a value of w 1 at which it is possible to achieve equalization of the pulse amplitudes at the MF output. Based on the optimization results, an MF layout was made. Quasi-static simulation was performed to validate the measurement results. In the experimental study, the attenuation was 6.6 times the half e.m. f., and the bandwidth was a MHz. Changing the boundary conditions at the ends of the passive conductor to short-circuit (SC) and open-circuit (OC) failures increased the attenuation to 7.7 times and the bandwidth to 70.5 MHz. In addition, the appearance of additional pulses during SC-OC is shown. The time of arrival of these pulses is determined by a linear combination of per-unit-length delay of the modes multiplied by the line length. The experimental and simulation results are in good agreement.

This article proposes an algorithm for detecting forest fires from RGB images obtained using an unmanned motor glider (UMG). The algorithm includes several stages related to finding and subtracting the background, highlighting the fire area in the RGB color space. The proposed algorithm has been tested on images of forest fires. The article proposes a variant of the flight of an unmanned motor glider in such a way as to continuously monitor large spaces for several hours. The results of calculations are presented, showing that the proposed method allows one to find areas of the image occupied by fire and can be used in automatic systems for monitoring forests from fires.

The computing unit (CU) of the computer vision system (CVS) has been developed based on a system on a chip (SOC) with the Xilinx Field-Programmable Gate Array (FPGA). A new model of a convolutional neural network (CNN) tiny-YOLO-Inception-ResNet2 related to neural networks of the YOLO subclass was proposed. A feature of this model is the presence of two Inception-ResNet modules. The weight coefficients of the trained software-implemented CNN of the same model were used. Images from the Pascal VOC 2007 dataset were used to train and test these CNN models. The research of the CU effectiveness was carried out. Firstly, we study the detection time of one image which spent in each layer of the CNN model and of the whole model depending on the number of universal computing units in the CU. Also, the study of the detecting objects accuracy depending on the bit depth (16 or 32 bits) of floating-point numbers was carried out. It is concluded that it is necessary to perform calculations using 32-bit floating-point numbers. It is shown that the power consumption of the CU did not exceed 12 Watts during all experiments.

The article presents the results of extracting the envelope of radio impulse signals using the digital processing methods. Three methods of extracting the envelope are studied in the work: correlation function; the Hilbert transform; and the new approach in which the combination of correlation function and Hilbert transform are used. For the research we used the measured reflectograms of the multilayer liquid. As a result of processing and comparing a variety of experimental characteristics the accuracy of determination of Hilbertcorrelation combination sequence was better than standard methods of processing. The resulting waveform is easier to analyze and process, but the processing need more time to calculate.

This article covers possible password attacks, describing thermal residue-based post factum password attacks and the ways to counteract the same, with test results provided as to the possibility of intercepting a password with a thermal imager. In the process of work theoretical material was studied, the methodology of testing the possibility of intercepting passwords, PIN-codes and graphic keys by residual heat trace was developed. The task of testing was that on different models of keyboards, as well as on a smartphone, a set of different combinations of characters, PIN codes and graphic keys was produced, then, using a thermal imager of the UNI-T model UTi260B photographs of the residual thermal trace were taken. The pictures were taken at different distances from the keyboard and after different times of typing the combinations of characters. In the course of this experiment, it was found that it is possible to obtain a sufficiently clear image within one minute after entering the password. However, in order to most successfully reproduce the sequence of the typed characters, the image should be made as early as possible. If the image is taken within fifteen seconds after the password has been entered, success in reproducing the character sequence is achieved in most cases. After thirty seconds, accuracy drops, and after forty-five seconds or more, it becomes increasingly difficult to reproduce the text. In cases of decryption of a graphical key, a similar heat attack makes it possible to reproduce the correct key form even forty seconds after input, as long as the key lines are not superimposed. As a result of the research, methods for counteracting residual heat trace attacks on passwords have been identified and formulated.
