Part one of this three-part series examines the rational for using control technology to reduce process variability ...

This application note describes a closed loop, computer- controlled, variable attenuator for the control of output power from a tunable laser. It is based on the combination of a 1/2 wave-plate and a ...

Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

The low-voltage variable speed drive (VSD) allows variable control instead of fixed-speed operation. These days, VSDs can reduce energy consumption by up to 30% on average—and as much as 80% in ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

You might have heard about Porsche's innovative Variable Light Control system or seen it in action in a video. It aims to provide shade and coolness inside the car. Read on and find out how exactly ...

NIT-Rourkela researchers have developed an intelligent control system for hybrid microgrids, managing solar, wind, and ...
