A worker is about to enter a confined space. Prior to entry, he reaches down to his belt and pulls out his gas monitoring device. He points the device into the confined space and initiates a scan of ...

Photoionization detectors (PIDs) are gas detection technology that can help businesses address this risk from the start, maintaining the highest level of short- and long-term safety for workers.

A few weeks ago, I installed an automatic water heater switch to my bathroom, but it was a crude device. What I really want to do is design a universal heater driver. That basic idea can be adapted to ...

The ABCs of PID control. Considerations for interfacing elements in the electrical circuit to accomplish those parts of the PID function for position control. Firmware code implementation.

In this study, a novel nonlinear PID controller is developed for a class of second-order nonlinear systems subject to uncertainties and external disturbances. The proposed control architecture ...
