The article provides an overview of wearable devices that improve the quality of user recognition of objects of the surrounding world, reveals the process of developing an intelligent module for recognizing objects of urban infrastructure for "sound glasses" - a device designed for blind users. The functionality of the module under development, its architecture is characterized, the process and results of neural network training for object recognition are described, and an algorithm for identifying the color of traffic lights is given. The results of testing the developed software module are presented. The software module created in this work is an integral component of a fully functioning device "sound glasses", the use of which will allow people with visual disabilities to get information about events and the surrounding environment and navigate even in an unfamiliar environment.

The article describes the development of a virtual emulator of the polyvinyl chloride drying process. The development of the emulator is implemented using the Omegaland development environment. The characteristics and functional structure of the polyvinyl chloride drying process in a fluidized bed dryer are presented. Mathematical models of elements of simulated system are considered, algorithm of their operation is characterized. The steps of developing a virtual polyvinyl chloride drying simulator are described. The flowchart is assembled in the OmegaLand Visual Modeler modeling environment. The fluidized bed dryer module was developed in the integrated development environment of Microsoft Visual Studio in the C++ programming language. The developed dryer model was integrated into the Omegaland library. The developed dryer model was tested in the emulation mode of the polyvinyl chloride drying process.
