Scientists have observed high-speed switching in Pb(Zr0.4Ti0.6)O3 thin films under applied rectangular electric field pulses. Unlike the slow ferroelastic domain switching expected for ceramics, ...

A multitude of devices, vehicles, tools and equipment possess rotating elements such as motors, gears and teethed targets. In many instances, the rotational speed of these elements needs to be ...

Machines need sensors and transmitters to operate reliably and consistently. All it takes is a small drop in air pressure or a slight jam to cause a machine to crash; these sorts of problems can often ...

Most modern vehicles come with two transmission speed sensors, which are responsible for monitoring the input and output shaft speeds of the transmission. These sensors send information to your car's ...

As the cost of components and pumps becomes more affordable, variable speed pumps are being used to increase the efficiency and reliability of water distribution systems in multi-story buildings.
