Minimax strategy of mechatronic converters efficiency improving relative to error decrease with velocity increase at the same time provides common dataware level rise. The analysis of usage possibilities of different type position transducers (PT) gives the advantages of resolvers. The subsequent processing of their output signals is performed by "Resolver-to-Digit" Converter (RDC) which provides displacement digital equivalent and digital or analog signals specifying its velocity and acceleration. With appearance new electronic component, including microcontroller, for increasing of accuracy of the measurements of the corner of the tumbling resolver possible to use such methods, which earlier realize was not on. Given article contains the offers about the most further development of the technical decisions for RDC of the corner. Replaceable elementary substracting section, traditionally used in all, without exception, schemes of the automatic regulation, on more "intellectual" statistical section, possible avoid the influence signals in sidebar to feedback on accuracy of the transformation.

“…Permanent magnets have been widely utilised in various applications [1][2][3][4][5][6][7][8][9][10]. Amongst them, cylindrical and ring shaped permanent magnets with diametrical magnetization have been widely used in electrical motors [11][12][13][14] and in position sensory systems [15][16][17][18] including human intention recognition [19]. The requirement for an accurate and fast-computed analytical expression of the magnetic field generated by a diametrically magnetised permanent magnet that can facilitate the design optimization of magnetic devices and modelling dynamical systems [20,21], leads to various ways of expressing the magnetic field of a permanent magnet of this kind.…”

Cylindrical/ring-shaped permanent magnets with diametrical magnetization can be found in many applications, ranging from electrical motors to position sensory systems. In order to correctly calculate the magnetic field generated by a permanent magnet of this kind with low computational cost, several studies have been reported in literature providing analytical expressions. However, these analytical expressions are either limited for an infinite cylinder or for computing the magnetic field only on the central axis of a finite cylinder. The others are derived to calculate the magnetic field at any point in three-dimensional (3D) space but only with low accuracy. This paper presents an exact analytical model of the magnetic field, generated by a diametrically magnetized cylindrical/ring-shaped permanent magnet with a limited length, which can be used to calculate the magnetic field of any point in 3D space fast and with very high accuracy. The expressions were analytically derived, based on geometrical analysis without calculating the magnetic scalar potential. Also, there is no approximation in the derivation steps that yields the exact analytical model. Three components of the magnetic field are analytically represented using complete and incomplete elliptical integrals, which are robust and have low computational cost. The accuracy of the developed analytical model was validated using Finite Element Analysis and compared against existing models.

Information technologies, robotics and mechatronics play an important role in modern medicine. The article shows that the use of information technology is an essential part of any activity of a specialist healthcare. The main goal of the medical technique development is the high accuracy and quality of service, efficiency of treatment, reducing the risk of harm to human health. However, despite advances in engineering and technology, health care professionals are not always aware of them, and engineers do not have full information on the needs of modern medicine. The article provides an analysis of the normative document that defines the strategy of the medical science development in the Russian Federation and analyzes the theoretical and practical background of the information technologies, mechatronics and robotics as a basis of an interdisciplinary approach in the development of medicine and engineering. The authors determined the causes of the low interaction between health professionals and engineers in solving multidisciplinary problems. The main reason is the isolation of specialists in various fields of knowledge and the lack of a clear strategy for commercialization. Pedagogical solutions to solve the problem are offered. The authors suggest that the approaches to the educational process should be changed. This will enable to improve the mutual understanding of health professionals and engineers in the course of continuing professional education. The result of training with the involvement of external experts will initiate research in their field, contributing to the global goal: the advancement of science in general.
