Development of technology and diagnostic equipment, low-frequency electromagnetic therapy and high-frequency electrosurgery for equipping stationary and mobile medical centers. An improved experimental sample of multichannel lowfrequency physiotherapy equipment has been developed. The device is an open type instrument capable of working with a wide range of different inductors in the frequency range from 1 Hz to 20 kHz and the intensity of the magnetic field in two ranges of 1...50 mTl and 10...500 mTl.
As the result of research work a comparative analysis of existing security systems of microprocessor-based systems was made with aim to identify their disadvantages and improvement prospects. Existing microcontrollers were explore with aim to protection from readers on current consumption are researched and to determine the real security of high end microcontrollers and suggest ways to improve it. The algorithm of discrete wavelet analysis and spectral analysis in polar coordinates was further developed.
