Patent ID: 7628359

Claim:
A system for identifying conditions conducive to the formation of ice, comprising: a pressure sensor system positioned to measure a static pressure and a total pressure; a temperature sensor system positioned to measure a total temperature; an air collection passage having an air inlet and an air outlet; a liquid water content sensor positioned in the air collection passage to measure a liquid water content of air in the air collection passage; and a processor coupled to the pressure sensor system, the temperature sensor system, and the liquid water content sensor, the processor being programmed with instructions to: determine a static temperature based at least in part on a measured total temperature; compare the static temperature to a first threshold temperature and a second threshold temperature higher than the first; compare the liquid water content to a threshold liquid water content; and if the static temperature is at or above the first threshold temperature and at or below the second threshold temperature, and the liquid water content is at or above the threshold liquid water content, direct an action associated with conditions conducive to ice formation.
