This humidity controlled switch circuit turns on and off an electrical load (for example a heater) depending on the moisture content of the surrounding air. The moisture is “sensed” with the help of a ...

The HS Series humidity switch, designed to control dehumidifying as well as humidifying, has a relative humidity (rh) range from 0 percent to 100 percent. The switch features nine user-defined ...

A material state known as super-lubricity, where friction between two contacting surfaces nearly vanishes, is a phenomenon that materials researchers have studied for years due to the potential for ...

UNIVERSITY PARK, Pa. — Sometimes friction is good, such as the friction between a road and a car’s tires to prevent the vehicle from skidding. But sometimes friction is bad — if you did not put oil in ...
