Further development of the biothermal analog computer /

An electronic analog computer, designed to enable calculation of the response of man to thermal stress, was developed. In accordance with equations previously developed (c.f. AD-428 144), the computer circuits were used to simulate the physical distribution of heat within the body, the thermal stress imposed by the environment, and the physiological mechanisms of homeostatic feedback. Computer predictions were compared with experimental results from cyclic thermal stresses furnished by Lieutenant Colonel W.C. Kaufman, AMRL, and agreement was found to be good. The computer was used to calculate human response to wearing of an unventilated anti-exposure suit. The technical aspects of the computer circuits are presented in detail.
