[A method for creating fuzzy neural-network models using the MATLAB package for biomedical applications].

Problems of MATLAB-based simulation of hybrid neural networks for data classification in biomedical applications are considered. The neural-network structure is used as a defuzzifier. Graphic interfaces for constructing fuzzy neural-network models are suggested. Methods for merging models constructed using different MATLAB packages and an algorithm for constructing a fuzzy neural-network model are suggested. The algorithm includes both modules for tuning membership functions of the fuzzy system fuzzifier, and modules for tuning the parameters of the defuzzifier implemented as a two-layer neural-network structure of the perceptron type.

[Bioimpedance means of skin condition monitoring during therapeutic and cosmetic procedures].

Engineering and technological problems of bioimpedance skin surface mapping are considered. A typical design of a device based on a PIC 16F microcontroller is suggested. It includes a keyboard, LCD indicator, probing current generator with programmed frequency tuning, and units for probing current monitoring and bioimpedance measurement. The electrode matrix of the device is constructed using nanotechnology. A microcontroller-controlled multiplexor provides scanning of interelectrode impedance, which makes it possible to obtain the impedance image of the skin surface under the electrode matrix. The microcontroller controls the probing signal generator frequency and allows layer-by-layer images of skin under the electrode matrix to be obtained. This makes it possible to use reconstruction tomography methods for analysis and monitoring of the skin condition during therapeutic and cosmetic procedures.

[A magnetic therapy apparatus with an adaptable electromagnetic spectrum for the treatment of prostatitis and gynecopathies].

Problems of engineering and algorithm development of magnetic therapy apparatuses with pseudo-random radiation spectrum within the audio range for treatment of prostatitis and gynecopathies are considered. A typical design based on a PIC 16F microcontroller is suggested. It includes a keyboard, LCD indicator, audio amplifier, inducer, and software units. The problem of pseudo-random signal generation within the audio range is considered. A series of rectangular pulses is generated on a random-length interval on the basis of a three-component random vector. This series provides the required spectral characteristics of the therapeutic magnetic field and their adaptation to the therapeutic conditions and individual features of the patient.
