Patent ID: 7427157

Claim:
A wind velocity measuring apparatus comprising: a processor; a first thermal sensor operatively coupled to the processor and having a first thermal absorbency; and a second thermal sensor operatively coupled to the processor and having a second thermal absorbency lower than the first thermal absorbency, wherein the processor is configured to receive from at least one of the first thermal sensor and the second thermal sensor a first temperature reading and a second temperature reading sensed by the at least one of the first thermal sensor and the second thermal sensor after a quantifiable amount of heat is applied to the at least one of the first thermal sensor and the second thermal sensor for a quantifiable amount of time, and wherein the processor is further configured to determine a theoretical temperature based on the quantifiable amount of heat, the quantifiable amount of time, the first temperature reading, and the second temperature reading and to determine a wind velocity based on the difference between the theoretical temperature and the second temperature reading.
