High Performance Ferrite Magnet Motor Developed - No Rare-Earth Required

By
New Energy and Industrial Technology Development Organization (NEDO) has announced that the organization, working together with a group of School of Information Science, Hokkaido University, successfully developed a newly structured rotor segment type of axial-gap motor for use of hybrid electric vehicles (HEV). 
The output performance of the new motor is comparable with the conventional rare-earth magnet motor although its magnetic material consists of ferrite magnets only without using any rare earth.  A result of actual load testing under a constant torque range shows 51.5KW which is equivalent to conventional HEV battery performance.

 This technology has been developed as a part of "technology development for the next generation high performance automobile battery systems ".  
The new technology has strong potential to relieve auto-manufacturers from extremely competitive situation in procurement of the rare-earth material which is supposed to be essential for the next generation vehicle development.

Wireless High-definition Quality Video Transmission Units

By
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

By
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

By
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
