Individual gauge for the microclimate index
First Claim
1. An individual device for determining the microclimate index of a person independently of that of other persons within the overall surroundings which comprises a base, means on the base for attaching the device to a person'"'"'s clothes, a closed container for storage of water mounted on the base, a wick having one of its ends submerged in the water and projecting outwardly from the container, a first means connected to said wick for thermoelectric sensing of the temperature of the wick wet with water and for emitting a signal having an intensity dependent upon the sensed temperature, a black-surfaced outwardly convex semispherical hollow metallic member supported with its open side facing said base and its black convex surface facing the surrounding atmosphere, a second thermoelectric sensing means for sensing the temperature existing in correspondence of the focus of the concave surface of said black surfaced member and for emitting a signal having an intensity dependent upon the sensed temperature, means for connecting said sensing means comprising adding the integrating means for conducting said emitted signals to an electromagnetic memory in said base for recording the emitted signals, and providing values for the equation:
-
space="preserve" listing-type="equation">0.3 tg+0.7 tu=Twhereintg is the signal from the first thermoelectric sensing means;
tu is the signal from the second thermoelectric sensing means; and
T is the microclimate index, from which said index is calculated, each of said components having a size which adapts the device to be supported on a person.

Abstract
An individual gauge for measuring the thermal stresses to which a person is subjected has minature components which adapts the gauge to be supported on an individual. The gauge has two thermoelectric sensors such as thermocouples one of which is associated with a water-wet wick and the other is associated with a black surface exposed to the surrounding atmosphere. The sensors are connected through adding and integrating circuits for emitted signals to an electromagnetic memory for recording the signals.
