Abstract

A meter for determining chill temperature and/or chill effect as a measure of comfort of an individual. This meter utilizes a sensor that is responsive to ambient temperature, wind velocity, humidity and/or solar effects. The sensor simulates a human body with normal covering for the prevailing real temperature, and electrical circuits are responsive to changes in effective temperatures due to these environmental factors. In one embodiment, the inner surface of the sensor is maintained at a selected constant temperature. The temperature associated therewith provides an error signal if a temperature differences is noted, this error signal causing current to flow to heat dissipaters to restore the select constant temperature. The amount of power required to maintain the selected temperature is a measure of the effect of the environmental factors and therefore relatable to chill temperature and/or chill effect. In another embodiment, a constant current is directed to a heater element within the sensor and a temperature sensor monitors the ambient temperature. The chill temperature signal is obtained from a change in the differential temperature between the sensor and the ambient. All embodiments provide for a visual display of a chill temperature value.
