Abstract
An instrument for sensing fatigue, includes a first temperature sensor for measuring a first temperature at a hottest spot of an uncovered part of a person's body; a second temperature sensor for measuring a second temperature at a coldest spot of an uncovered part of a person's body; and a comparator connected to the first and second temperature sensors for generating a temperature signal representing a temperature difference between the first and second temperatures.
Claims16
A method of monitoring fatigue of a person performing a tiring activity and of preventing effects of fatigue, comprising the following steps:
- (a) while the person is at rest prior to performing the activity, taking a first temperature at a hottest spot and a second temperature at a coldest spot of the person's head;
- (b) repeatedly taking said first and second temperatures during the activity;
- (c) calculating a temperature difference between said first and second temperatures;
- (d) monitoring a change of said temperature difference during the activity;
- (e) generating a signal when said temperature difference exceeds a predetermined value.
The method as defined in claim l, further comprising the step of triggering, by the signal generated in step (e), a refreshing treatment administered to the person.
