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 ...

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 ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

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.

Spending more time in glucose range could help reduce adverse pregnancy outcomes, but available closed-loop insulin delivery systems are not customized to pregnancy-specific needs. In a randomized ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The Christian Science Church, and we’ve always been transparent about that. The Church publishes the Monitor ...

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 ...
