The MathWorks has announced the availability of two new and three upgraded products for engineers developing closed-loop control systems. These tools work within the Simulink environment to expand the ...

Electronic control logic and system components are described that are used with a venturi carburetor to accomplish the fuel metering required in a closed loop emission control system. Special open ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

This new study of pediatric patients with type 1 diabetes from France and Belgium investigated the effectiveness of insulin delivery via closed-loop and open-loop systems. Closed-loop delivery of ...

Every plant in the process industry most likely has several control loops that do not perform well. Although there are many factors that may negatively affect control loop performance, a few of these ...

The possible advantage of hybrid closed-loop therapy (i.e., artificial pancreas) over sensor-augmented pump therapy in very young children with type 1 diabetes is unclear. In this multicenter, ...

A closed-loop system of insulin delivery (also called an artificial pancreas) may improve glycemic outcomes in children with type 1 diabetes. In a 16-week, multicenter, randomized, open-label, ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

This is a representation of the drug delivery system. Serving as the acoustic indicator of drug delivery dosage, the microbubble emission signal y(t) is used to find the expected controller output u(f ...

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.
