Battery management systems (BMSs) are designed to protect the batteries and predict their charge level. They use circuit models often derived from electrochemical impedance spectroscopy (EIS) measurements to construct an equivalent circuit model (ECM) that consists of resistors and capacitors connected both in series and in parallel. Yet, ECMs do ...

Tim Poole, JDR Cables, Cambridgeshire, UK and Mark Yeoman, Continuum Blue, Hengoed, UK

JDR Cables designs-to-spec and manufactures subsea umbilical systems of cables and reelers for the oil and gas and renewable energy industries. In these designs, the harsh environments of deep water pressure, wind and waves, as well as the rough ocean floor must all be considered, along with the forces acting on cables from being pulled and ...

Rautaruukki Oyj supplies metal-based components and systems to the construction and mechanical engineering industries, where process engineer, Mika Judin, works with optimizing their coating technologies. When coating rolled metal with paint, it is important that the coating be applied such that it is not discolored or damaged, and that it is ...

Leopoldo Rossini, Emmanuel Onillon, & Olivier Chetelat CSEM SA, Neuchatel, Switzerland

CSEM is a private applied research and development center specializing in micro-technology, system engineering, micro-electronics, and communications technologies. One of their latest projects is working on minimizing the weight of satellite attitude control systems as every gram of payload matters when launching a satellite into orbit (€15,000 ...

Francesca Magionesi INSEAN Italy

There has been a recent move towards utilizing bulbous bows on ships to house different types of sonar systems, but it is not definite how much structural vibration might interfere with the functioning of a transducer array inside the sonar dome. INSEAN, the National Institute for Studies and Experiments of Naval Architecture in Italy, needed a ...

O. Craciun, and colleagues ABB AG Ladenburgh, Germany

When a tree branch touches overhead cables and causes a momentary short circuit, your lights may flicker. A device called a recloser ensures that power to your home is not cut off for a longer period. ABB AG, a leading manufacturer in power technology, is working towards designing a more reliable recloser. One objective in this design process ...

J. Yang, M. Perrin, P. Lalanne CNRS, France

Nanoresonators, or optical nanoantennas, manage the concentration, radiation, and absorption of light at the nanometer scale and show stunning promise for future improvements to technology, such as sensors, computers, and other electronics. However, the ways that these devices scatter light and interact with their surrounding environment are not ...
