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 ...

Open-loop stepper motors have held a prominent position in automation applications over the years due to their simplicity, excellent positioning, and low cost. However, as manufacturers utilize faster ...

Two Ro-Ro vessels owned and operated by Stena Line are to be retrofitted with Wärtsilä in-line closed-loop scrubber systems. The scrubbers will be installed on the Stena Transit and Stena Transporter ...

Stepper motor systems are highly efficient when producing torque, but lack operational efficiency when not producing torque. Applied Motion Products offers insights on how to make a greener and more ...

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 ...

An open-loop cooling system, also called raw water cooling, draws water directly from the body of water the boat is floating in, whether it's saltwater or freshwater. That water is pulled through a ...

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, ...
