Abstract
A method and apparatus for monitoring heat stress, wherein the apparatus may include a skin surface temperature probe and heart rate probe that do not require direct physical contact to a user'"'"'s skin. The method includes the steps of: measuring a plurality of physiological parameters including at least heart rate and skin surface temperature of a user; calculating at least body core temperature of the user as a function of the plurality of physiological parameters using a predetermined algorithm; comparing at least heart rate and body core temperature to corresponding maximum thresholds; and alerting the user when at least one of heart rate and body core temperature exceeds the corresponding maximum threshold.

16. A sensor for measuring skin surface temperature of a user comprising:
-
a first portion comprising a thermally conductive material having a first plurality of temperature measuring devices coupled thereto and having a first face adjacent to a first surface of the sensor;
a second portion comprising a thermally conductive material having a second plurality of temperature measuring devices coupled thereto and having a second face adjacent to the first surface of the sensor; and
a third portion coupled between the first and second portions and substantially thermally isolating the first portion from the second portion, wherein upon the first surface of the sensor contacting a second surface that is adjacent to a user'"'"'s skin surface a difference in heat flux between the first and second portions is generated and measurable based on the first and second plurality of temperature measuring devices, the measurable difference in heat flux for use in determining skin surface temperature of the user. - View Dependent Claims (17, 18, 19, 20)
