Annotation: Objective: To explore key methods for developing grip strength in wrestlers, compare their effectiveness, and offer recommendations for integration into the training process. Methods: Review of scientific literature, observation of practical applications in wrestling training, and testing the effectiveness of methods (dynamometry, hold duration, and forearm fatigue resistance tests). Results: The most effective exercises for developing both isometric and dynamic grip strength were identified. It was found that combining specific grip-focused movements with functional wrestling-based drills improved performance by 17–25% compared to traditional forearm isolation training. Conclusion: Targeted grip strength development enhances wrestling technique effectiveness, reduces injury risk, and improves endurance during bouts.

Annotation: The article discusses the theoretical foundations and practical application of fiber-optic sensors (FOS) for detecting gas leaks and monitoring temperatures at industrial facilities. A comprehensive analysis of the operating principles of FOS, their classification, signal modulation methods, and distributed sensing is carried out. Particular attention is paid to their application in aggressive environments, including in the oil and gas, chemical, and energy industries. The advantages and limitations of the technology are presented, as well as the prospects for its development within the framework of industrial digitalization and the implementation of IoT solutions. Directions for further research, including intelligent signal analysis, increased selectivity, and standardization of application are considered separately.

Annotation: Modern intelligent multidisciplinary digital technologies, incorporating elements of artificial intelligence and artificial neural networks, generate numerous complex psychological nuances and product marketing aspects during their development, especially when interacting with TRIZ and ARIZ. The emergence of information technologies and the drastic reduction of the time cycle required to transform an inventive idea into a real, market-demanded, and viable product, along with the increasing complexity of the technical and technological components of new products—which proportionally raises the cost of prototype manufacturing and testing—necessitate a fundamentally new approach to creating technical solutions. These solutions may include auxiliary innovative functions, often non-obvious at first glance. Several fundamental directions have a decisive influence on the fate of new ideas under today's conditions. Taking these into account can ensure a high level of commercial success; conversely, ignoring them may permanently close the path to commercialization of the idea in any form.

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.
