High Coercivity Neodymium Magnet without Using Heavy Rare Earth Element Dysprosium

The National Institute for Materials Science (NIMS) announced that its Magnetic Materials Center developed a method for increasing the coercivity of neodymium magnet powder without using dysprosium (hereinafter, Dy). Dy is a heavy rare earth element that is normally essential for achieving high coercivity in neodymium magnets for traction motors of hybrid vehicles (HV). NIMS says that this technology developed led to an increase in coercivity of more than 20% without using any heavy rare earth elements such as Dy.

According to the NIMS' press release, 90% of Dy is almost dominantly produced in PRC. Hopefully, this technology will relieve us from the absolute dependency on the single country at least.

Wireless High-definition Quality Video Transmission Units

This system that consists of a receiver (left) and a transmitter wirelessly enables HD (30 frames/sec) quality video and stereo sounds transmission but with no compression and no delay time. The supplier, Giga Techno Vision's blog says the system is well secured because of its proprietary and patented technologies that differ its digital modulation method from wireless LAN. - Frequency Area 2.4GHz - Transmission power: 10 mW - Radio Channel Capacity 4ch Maximum - Diversity Method: Space-diversity 2 antennas - Size (Tx & Rx each): 110(W) x 80(Ｄ) x 30(Ｈ)mm - Weight (Tx & Rx each): approximately 300g - Transmission distance: 500 m outdoors (up to 3 km) There seem to be various applications, such as remote monitoring, CCTV, home video theater application, surveillance systems, etc. I hope in the near future the system become one single chip for receiver and transmitter each. When the chip becomes available, it will significantly broaden its applications to personal and ...

Intelligent humanoid robot that can learn and make decision by itself

This reminds me of the famous movie film screened more than 40 years ago. HAL was the name of computer that kicked out people from the space ship because it learnt the people's minds from their lips that they had questions on HAL's loyalty. Growing with further development of hardware and software capabilities, this humanoid robot may have the capability that controls real humans. I hope it will not come true and real even in the future space where highly intelligent humanoid robots will have to have strict limitation not to control humans. 8/24/11

Holographic Display

National Institute of Information and Communications Technology (NICT) has announced that the institute successfully developed the electron holography method stereoscopic technology which enables the ultimate viewing zone angle of 15 degrees and 4 cm diagonal display size color video display . In this development, by applying its own display technology to increase viewing area to high-resolution device with 3300 mega-pixels, the newly developed device is able to gain three time wider viewing zone angles than conventional devices and about two times broader two times broader video holographic display. It seems that 3D video display technology development is accelerated to bring us to a virtually "real" world without glasses. Source: NICT's news release (Japanese) 9/28/10
