Successful Demonstration of New Principle of Organic Solar Cells Operation

Advanced Industrial Science and Technology (AIST) announced on November 24, 2010 that AIST successfully demonstrated operations of a new type of organic photovoltaic devices (solar cells organic) using optical absorption due to charge transfer between the different organic molecules. Organic solar cells are expected as new technology for manufacturing solar cell sheets that can be bent, lightweight, and now, have been actively studied and developed worldwide. This time, successful photoelectric conversion from near infrared light over the wavelength of one μm was confirmed using the photovoltaic devices fabricated using organic molecules consisting of two molecules. This technology based on the new principle will enable more effective energy conversion from the light to electricity.

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

Broad Range of UV LED Applications

UV LED has a great potential for various applications and devices, such as a sensor, an indicator, an air cleaning device, a resin hardening device, lighting and display, and even in biotechnology field. A curing unit equipped with 25 pcs of UV LED Module (photo above) is for UV curing, one of the possible applications. The optical output power is more than 3W. The above video demonstrates one of display applications for fun. Nitride Semiconductors , a highly specialized supplier of UV LED, describes its self with four bullets, Cutting Edge ( Waza in Japanese), Ecology ( Yawaragi in Japanse ), High Quality ( Takumi in Japanese), and Fun ( Tanoshimi in Japanese) that is quite impressive and right fit in the present world.
