Submarines create underwater electric potential (UEP) signatures when using corrosion protection systems. These signatures are detectable by enemy vessels, an undesirable effect of the corrosion protection. Germany’s Technical Center for Ships and Naval Weapons (WTD 71) has worked with the Laboratory for General and Theoretical Electrical Engineering (ATE) at the University of Duisburg-Essen ...

ABB AG, Ladenburg, Germany
Transformers have been around for quite a while but their fundamentals are still being investigated by ABB in Ladenburgh, Germany. The ABB Corporate Research Centre is currently developing sophisticated magnetic sensors, using finite element analysis (FEA) to investigate the way in which external electrical sources and loads impact a magnetic subsystem like a transformer core. Their goal is to ...

Siemens Corporate Technology, Munich, Germany
Siemens is a technology company working with electronics and electrical engineering in industry, energy, and healthcare. Researchers at Siemens Corporate Technology are experimenting with an energy harvesting MEMS (Micro Electro-Mechanical System) generator. In collaboration with Continental AG, they are designing a MEMS device for use as a Tire Pressure Monitoring System (TPMS). The movement of ...

Migrating the electrical grid to a “smart grid” is usually discussed in terms of IT issues or embedded systems. Yet, just as important updating the “nuts and bolts” of the smart grid. At ABB AB Corporate Research Power Technologies in Sweden, scientists are working to reduce line current and the resulting resistive loss in cables caused by the use of increased voltage in modern ...

Metamaterials are manufactured, structured materials that they can interact and manipulate wave phenomena such that objects surrounded by metamaterials are shielded from these waves. In the case of light, metamaterials make these objects ‘invisible’. Researchers throughout the world are applying these materials to many different applications. At NASA Glen Research Center, physicists are ...
Numerical Simulation-Based Topology Optimization Leads to Better Cooling of Electronic Components in Toyota Hybrid Vehicles
Toyota Research Institute of North America, MI, USA
The Toyota Research Institute in Ann Arbor drives cutting-edge research in energy efficiency, mobility infrastructure, and safety. Here, Ercan Dede and his team are designing heat sinks (or cold plates), which are affixed to fragile electrical systems and other applications in Toyota’s hybrid vehicles. Their simulations simulate the cold plate’s topology for improved cooling efficiency ...

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 per kilogram). CSEM hopes to accomplish this task ...
Salzgitter Mannesmann Forschung, Duisburg, Germany
Salzgitter Mannesmann Forschung (SZMF) advances testing methods for the Salzgitter Group, a leading company that works with the manufacture of, among other things, pipes. In the manufacturing of heavy steel tubing, it is important maintain quality, which is done through conduct non-destructive testing (NDT) using large magnets to identify flaws (magnetic flux leakage inspection). Oliver Nemitz ...

The Neuromodulation Group at Lahey Clinic conducted a study based upon spinal cord stimulation (SCS). SCS involves implanting a series of electrodes that apply electric potential to the spine, interfering with pain signaling circuitry. It’s used to alleviate chronic back and leg pain. Although the treatment remains effective for years, the electrodes must be reprogrammed through trial and ...
