PHYSIOLOGICAL PARAMETERS MONITORING SYSTEM Russian patent published in 2007 - IPC A61B5/205 

FIELD: medicine; measuring technique.

SUBSTANCE: system can be used at continuous viewing of several physiological parameters, for example, parameters characterizing cardiac and breathing activity of human operator including its dynamics through one communication channel, for example, at increased requirements claimed to measuring equipment, in particular, onboard of flying vehicle or under conditions of space flight. System has transmitting unit and receiving unit, which are connected with transmitting aerial and receiving aerial correspondingly. Transmitting unit has first and second detectors, first and second analog-to-digital converters, high frequency oscillator, phase manipulator, frequency manipulator and power amplifier. Receiving unit has radio receiver, demodulation unit and registration unit. Radio receiver has reference oscillator, second phase detector, control signal former, heterodyne, mixer and intermediate frequency amplifier. Demodulation unit has first, third and fourth phase detectors, phase doubler, first, second and third PLL units, first, second and third phase halver, frequency demodulator and adder. System provides increase in range of activity and increment in noise immunity due to usage of complex signals with combined phase and frequency manipulation at one carrier frequency.

EFFECT: improved characteristics of system.
