Claims (2)

1. A method of monitoring the functional state of a person, which consists in remotely irradiating a portion of a person’s body using an ultra-wideband radar located outside or inside the mobile phone’s body, receiving reflected signals modulated by the movement of tissues of the body part due to cardiac activity, emitting heart rhythm signals, which include in the transmitted communication message, while irradiating a portion of the human body is carried out by a sequence of ultra-wideband electro agnitnyh 0.2-1.0 ns pulse duration, repetition rate 0.05-30 MHz and an average power flux density on the irradiated portion of the human body not higher than 0.2 mW / cm ^2, from the received reflected signal component recovered modulation pulse repetition frequency due to cardiac activity, according to which a heart rhythm signal is generated, a dynamic series of cardio intervals is formed from heart rhythm signals, according to the results of a spectral analysis of which the stress index S of a person is estimated from the ratio

where LF and HF are, respectively, the low-frequency (from 0.04 to 0.15 Hz) and high-frequency (from 0.15 to 0.4 Hz) components of the spectrum power of the dynamic series of cardiosignals, and under standard measurement conditions (peace, lying on your back) the value of the stress index S for the average operator is considered equal to unity and its value is included in the transmitted communication message of the mobile phone, characterized in that they periodically measure the voltage of the electromagnetic field and normalize the difference signal of the two measurements, in this case, the previous measurement of the electromagnetic field strength delays in time and it is calculated from the subsequent measurement of the electromagnetic field strength, the resulting difference signal is integrated, the difference signal is divided into an integrated difference signal, the obtained normalized signal is compared with a predetermined threshold value and, if the threshold level is exceeded, they are transformed normalized signal to digital form and evaluate the stress index of a person. 2.
