Annotation: A real-time active online monitoring system for leather manufacturing processes is presented, fully tailored to the specific requirements of the leather industry. The system employs contactless resonance sensors as a key component, integrated across all stages of hide processing—from soaking (used to remove preservatives, dirt, and blood), liming, hair removal, and deliming to tanning (including vegetable tanning), dyeing, fatliquoring, drying, and finishing. The importance of continuous parameter monitoring in the "dead zones" of technological tanks is highlighted, along with the design of the sensor module (a sleeve with a solenoid coil) and its manufacturing methods, including the application of RITM technologies. The paper outlines approaches to integrating the sensors into the production line and discusses the anticipated benefits: improved uniformity of hide processing and final leather quality, reduced defect rates through timely detection of deviations, and automatic real-time adjustment of processing modes according to raw material properties.

Annotation: In a modern society, implementing and organizing various options for the comprehensive, multifaceted development of an innovative economy, especially in areas related to smart production and technology, stress loads of all kinds that arise in the most active organizers of project development processes and generators of new technical and commercial ideas aimed at optimizing and accelerating development processes require an adequate response and unobtrusive, but extremely reliable and natural technologies and special equipment for rehabilitation; The publication shows models of system control and regulatory complex model subsystems using contactless resonant sensors as dynamic links between a mobile controlled object and mobile communication facilities, operating on the principles of electromagnetic resonance spectroscopy and having different design versions.

. Monitoring the quality of drinking water and milk//Science online: International Scientific e-zine - 2025. - №4. - https://nauka-online.com/en/publications/technical-sciences/2025/4/17-9/

Annotation: The quality of drinking water practically determines the quality of life. In all methods of water quality control, it is accepted that the conductivity of water is a clear indicator of its purity. Almost all existing technologies, devices and equipment for water quality control have a very narrow range of technical capabilities and do not cover all the parameters that must be constantly monitored in order to prevent water from reaching the user that, due to the above reasons, is contaminated to such an extent that it poses a danger to human life and health. Milk is one of the most important products in a complete diet, and since a significant percentage of its composition is also water, it requires equivalent mobile, reliable and accurate control technology, adapted both to the increased quality requirements of milk and to new visions of regulatory requirements for quality. Based on this far from complete set of information, one can make a reasonable conclusion about the need for constant monitoring of the quality of milk and water before use, especially in relaxation processes;
