Underwater radiated noise from anthropogenic structures must be reduced to protect the marine environment. Active vibration isolation that can reduce generated sources by providing counteracting forces solve this issue. This paper presents a 120 N class electromagnetic inertial mass linear actuator for an active control system in large ship. The proposed is operated based on Lorentz force, also...

We present a new methodology to create colorful textile antennas that can be embroidered within logos or other aesthetic shapes. Conductive threads (e-threads) have already been used in former embroidery unicolor approaches as attributed to the corresponding conductive material, viz. silver or copper. But so far, they have not been adapted to ‘print’ colorful textile antennas. For the first tim...

*Work supported by the U.S. Department of Energy under contract No. DE-AC02-98CH10886. [email protected] Abstract High field common coil magnets [1,2] using brittle High Temperature Superconductors (HTS) or Nb3Sn cables provide new challenges with respect to the design and manufacturing of coils. We are developing the scaleable techniques that can be used in the production of common coil or oth...

The yarn suction gun (YSG) is used to draw the running in initial phase and when changing bobbin a continuous production usually operated with compressed air. With typical overall efficiency of air generation, treatment delivery, electrical power requirement increases over 75 kW just operate single YSG. Such high consumption must be addressed. One most effective ways reduce cost generation repl...

In recent years, the rotating electromagnetic field eddy current (RoFEC) testing technique has attracted widespread attention due to its various advantages for inspecting tubular structures. However, most of related work was focused on detecting inner wall defects metal pipes using feed-through probes, which are often not applicable outer defect detection. This pushes forward encircling RoFEC a...
