Fan control is an important aspect of system architecture. Though often left as a secondary activity, its implementation has significant effects. Customer response can be immediate to factors such as ...

Closed-loop control systems of insulin delivery may improve glycemic outcomes in young children with type 1 diabetes. The efficacy and safety of initiating a closed-loop system virtually are unclear.

In part because they are closed-loop systems, it can be easy to ignore power plant cooling water systems that support the reliable functioning of everything from stator bars in the generator to ...

Currently, one closed-loop system, the Medtronic MiniMed 670G, is in commercial use in the United States, but randomized trials are needed to assess its efficacy and safety. 8 Such a system, which ...

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 ...

Self-regulating systems with feedback loops, i.e., the routing back of the output of a system to its input, have existed since antiquity and have since become an integral part of modern technology.

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 ...
