Latest Patents

Caspari holds a patent for a thermal anemometer that separates sensor heating from sensor temperature measurement through a switched sampling technique. This invention demonstrates several advantages over traditional circuitry that employs a bridge, which simultaneously heats the sensor and senses the ambient and velocity sensor temperature. In his thermal anemometer, sensor temperature is determined by sampled measurement of its resistance. The control of sensor temperature is achieved by varying the voltage applied to the sensor, with an error value determined by the difference between actual sensor resistance and the desired resistance. This innovative method enhances the accuracy and efficiency of thermal anemometers.
