The methods of biosignals processing and their implementation in the structure of the system of impaired human communicative function compensation

Abstract

The methods of biosignals processing and structure of the system of impaired human communicative function compensation are proposed. The methods of biosignals processing are based on the application of spectral-correlation analysis methods using the sliding window method and include preparatory and main stages. The sequence of steps of biosignals processing at the preparatory and main stages is substantiated. Also technical parameters and features of practical realization of constituent elements of the system of impaired human communicative function compensation are offered. The principle of operation of the system is based on the parallel selection and processing of electroencephalographic and electromyographic signals. At the same time the features of electrode constructions for selection of electroencephalographic signals, which are widespread today, as well as possible artifacts that will arise in the process of selection of these signals are analyzed. The design of electrodes for registration of electroencephalographic and electromyographic signals is proposed, the selection and processing of which is the basis of the method of indirect compensation of the impaired communicative function, which is realized by this system. A variant of realization of the functional diagram of the block of biosignals selection is proposed. The proposed design of the system of impaired human communicative function compensation can be manufactured using 3D printing technology, which will reduce its cost.
