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 ...

This paper describes the recent efforts on developing an automotive climate control system throughout integrating an electrically-controlled variable capacity scroll compressor with a fuzzy logic ...

We tackle the problem of selecting from among a large number of variables those that are “important” for an outcome. We consider situations where groups of variables are also of interest. For example, ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience ...

Just over a decade ago, an article titled, "Advanced Control Strategies Move into the Field" (Control, October 2008), highlighted three evolving trends in the process control world that would "make ...

The new SuperK VARIA from NKT Photonics is a computer-controlled variable bandwidth filter that effectively turns a supercontinuum white light source into a powerful single-line laser. Designed for ...

Variable-frequency drive (VFD) control panels, the Endura™ line, has been introduced. The Endura PB (Pressure Booster) Control Panel is designed for commercial pressure booster applications using ...

Here’s a breakdown of the various clutches and brakes used to control production speed—a crucial factor in virtually any industrial setting. Electric clutches may not be always the engineer’s first ...
