SAN DIEGO — The next advance in spinal cord stimulation (SCS) could be a closed-loop system that uses evoked compound action potentials (ECAPs) to maintain therapeutic activation, results of the phase ...

Figure 1. A closed-circuit cooler. Photos courtesy of Evapco. It’s a common question during the early design phase of large mechanical systems: Is open- or closed-loop cooling equipment better suited ...

Some operational amplifiers (op amps) have an inductive open-loop output impedance, which can be more complex to stabilize than op amps with resistive output impedances. One of the most common ...

Closed-loop pumped-hydro storage offers more chances to minimize environmental effects on water sources and overcomes the problem of finding suitable sites. According to an Australian research team, ...

In 2012, Automation World published an article looking at the decision factors faced when choosing electric or pneumatic actuators. More than a decade later, manufacturing engineers and OEMs still ...

People with type 1 diabetes require continuous insulin treatment and must regularly measure their glucose levels. With open-loop therapies*, insulin administration is manually controlled, while hybrid ...
