MODIFICATION AND APPLICATION OF THE BIOTHERMAL ANALOG COMPUTER.
Abstract
The present report is the third in a series on the electronic analog simulation of the human temperature regulation system. The objectives of the present work were (1) to redesign the original computer circuit to improve reliability; (2) to extend the computer capability to enable simulation of response to solar (or other point source) incident heat load; (3) to compute human survival time for a subject confronted with high heat loads and high ambient humidity. The first objective was realized by substituting electronic for mechanical elements in the computer. Equations relating body heat load to incident solar radiation were developed and the simulating circuits designed and constructed to realize the second objective. The third objective, simulation of hot, humid environments, resulted in the recommendation that exposure to high temperature (45-50C) should be limited to 0.5 hours, with progressively greater exposure time permissible at lower environmental temperatures.
