Abstract : An Author Certificate has been issued for a device used to record human physiological functions. Its components include amplifiers of biopotentials, high- and low-frequency filters, a body and skin temperature monitor, a circuit measuring skin galvanic reactions, and a stabilized power source. Increased operating reliability and accuracy of several simultaneous measurements are achieved by suppressing synphased interference and by assuring necessary signal amplification using cascaded low-frequency amplifiers. Some signals are fed to bridges, in which the arms are automatically balanced by controlling each arm using a tube grid connected via resistance to the cathode. A variation of the above is distinguished by the fact that the temperature measurement bridge is fed by a synchro. A second variation is designed to record incoming signals from measurement channels via telemetry, and uses various types of oscillographs. It contains output stages with current and voltage switches.
