The technological process in the industry is inextricably linked to its automation of technological processes. Automation is effectively used at the present stage of human development to achieve growth in resource efficiency, improve environmental quality and reliability of products. Due to the rapid
development of microprocessor technology and personal electronic computers, the functionality of which enables the use of the most advanced methods within the modern complex control systems. Microprocessor devices and electronic computers interconnected by computer and control networks using common databases allow the introduction of computer technology in the non-traditional field of activity of the enterprise, which is manifested in the integration of production processes and management. The basis of automation systems were the functionality of microprocessor control systems, in the creation of which factors such as the use of principles of integration, distributed control, software systems play a crucial role. When automating production, the object is not a separate technological process or unit, but a technological complex with complex interconnections between its subsystems.

Today, wireless data technologies have become an integral part of our lives. They are widely used by consumers of both conventional and professional equipment. The exception was not non-destructive control.
If we look at existing non-destructive devices and systems that use wireless data transmission, we will see that in the vast majority of them, such technologies are used as ancillary and not used to transmit raw data about the object of control.
In this work, wireless technologies are used not only to transmit reports on the state of the object of control, but they also help to "communicate" the sensor with the primary converter and the unit of reception and processing of information. In this work, this unit is a smartphone.
The smartphone as a complex device today has high computing capabilities, a complete set of the most widespread technologies of wireless connection, as well as a flexible software shell. It is these advantages of this type of devices that allow them to be used in non-destructive testing tasks.

Purpose: increasing the information content of medical thermograms by thermostabilizing the optical system of the thermal imager and introducing software tools for processing thermograms.

Main results: Defocusing problem of thermograph lens under the ambient temperature effect is considered in this article. Optical scheme of the IR triplet is propose, which parameters are calculated using the method of passive optical athermalization. Based on the proposed method of thermograph thermoresponsive lens filling and further optimization was designed ternary diagram of temperature-compensated infrared lens matrix with a dimension of 320x240 pixel 25x25 mkm. Thanks to this method, and the calculations in the mathematical software Mathcad has been received a number of termaltake triplets infrared spectral range combinations of 8-14 microns. At the same time was achieve thermal stabilization and system achromatization.

In this master's thesis an automatic ultrasonic control system for pipes using LRUT technology was developed. This topic is relevant today as automation and large volumes of non-destructive testing require systems that can handle this. The system proposed in this paper consists of modern technologies in UZK. To ensure acoustic constant contact between the object of control and the system, the latest ideas are used. The simulation of the system was carried out using modern software. Also, development of a potential startup of the project was conducted, and the possibility of the system's exit to the international and domestic markets was considered.

The purpose of the master's thesis is to explore the possibility of using ultrasonic control of large diameter and size pipes.
The developed system can be applied to non-destructive control as a primary or auxiliary. Also, due to the versatility of the algorithms, work with minimal changes can be rebuilt for another way of finding defects in the pipelines.

The presented paper contains 73 pages, 28 illustrations, 22 tables and 31 names of the used sources.

In the master's dissertation the review of literary sources on the subject of diagnostics of a person's view was conducted. Defects and visual impairments, as well as the possibility of their detection, are described. The main focus on the review was the violation of the perception of color by the human eye and the existence of systems by which such violations can be detected. On the basis of the review of literary sources, a functional scheme was developed and a selection of elements was made that allow automating the diagnostic process of the system. Synthesis of the system with the use of software, in coordination with elements of the functional scheme is executed. Also in the dissertation there is a section of the development of the startup project, which describes the possibility of the release of this system on the market and to compete with existing analogous systems.
