FIELD : medicine.SUBSTANCE : method for controlling devices by processing electrical signals arising in the muscles of a person relates to medicine. In this case, the electromyogram sensor registers an electrical signal that occurs in the user' s muscle when it is stressed. Signal is registered by reusable non-invasive electrodes on the surface of the user' s skin. Sensor processes the registered electrical signal; in the process of processing, amplification and filtering are performed. Electromyogram sensor microcontroller converts a signal to a digital value using an analog-to-digital converter, generates a data packet that contains the name of the electromyogram sensor and the digital value of the signal, sends the generated data packet to the computing module. Compute module accumulates an array of digital signal values, calculates the amount of electrical muscular activity of the user after the accumulation of the number of digital values of the signal, calculates the difference between the maximum and minimum values of the above signal in the accumulated number of digital signal values and multiplies the obtained difference of the mentioned values by a numerical factor taking values from zero to one and determining the degree of contribution of the calculated signal value in relation to the calculated signal value earlier, and adds to the obtained difference between the maximum and minimum values of the above signal in the accumulated number of digital values of the signal multiplied by one minus the given numerical factor, taking a value from zero to one. When calculating the difference between the maximum and minimum values of the above signal for the first time, in the absence of a previously calculated difference between the maximum and minimum values of the signal in the accumulated number of digital signal values, to the calculated difference between the maximum and minimum signal values in the accumulated number of digital signal values multiplied by a numerical factor taking values from zero to one and determining the degree of contribution of the calculated signal value with respect to the calculated h The signal is previously added, nothing is added. Radio module transmits a control signal to a controlled device to control a controlled device or an element of a controlled device.EFFECT : increase in the accuracy and speed of processing electrical signals that occur in the muscles of a person, and the control of devices are achieved.6 cl, 8 dwg
