Abstract: FIELD: medical technology.  
     SUBSTANCE: digital device for monitoring the physiological health indicators of an aircraft pilot contains blocks of red and infrared emitters, a photodetector, an analog-to-digital converter, a synchronization unit, operational and permanent storage devices, a computer unit, the first and second comparison nodes, an indication and notification unit. The device contains an additional infrared emitter unit, a yellow-green emitter unit, barometer, accelerometer and altimeter units, as well as a memory unit. An increase in the level of control of the pilot’s tolerance to the effects of adverse factors during the flight is achieved by introducing the possibility of synchronous parallel recording of the current parameters of the pilot’s health: the level of blood saturation, and environmental factors, the values of atmospheric pressure, the magnitude of the experienced overloads caused by accelerations, flight altitude, which, with subsequent analysis, will provide corrective actions to be introduced into the pilot’s ground training aimed at increasing the level of resistance to the effects of overloads, as well as reduced (increased) atmospheric pressure and altitude. In addition, the study of all fractions of hemoglobin: methemoglobin (MetHb), oxyhemoglobin (HbO2), deoxyhemoglobin (Hb) and carboxyhemoglobin (COHb) is provided, which makes it possible to determine not only functional blood saturation, but also fractional.

Granted: 1984-09-06
Abstract: A first epicyclic gear train divides the input power between a first path, containing a hydrodynamic converter and a second, purely mechanical one coupled to the output shaft. A second epicyclic gear train between the converter and output shaft has a hydraulic brake holding one of its members stationary, whose actuating piston is subjected to the fluid pressure at the converter outlet. An auxiliary pump supplies the system with working and control fluid, while a brake holds the converter impeller so as to transmit power solely via the mechanical path. The piston is stepped, with two pressure faces acting in the same direction and hydraulically fully insulated from each other. Both can be subjected to the converter outlet pressure. A relief valve in a passage from the converter chamber periphery to the piston determines the outlet prrssure, while an inlet admits air to the chamber. The operating pressure of the relief valve is steplessly adjusted by an electromagnet (52).
