Smart Grid

By
There must be a variety of leading edge technologies and components required for Smart Grid which is recently assumed as the next generation electric power distribution network.

Electric power has been supplied by an electric power company to every building or facility wherever needed. "Internet" is often used as an analogy of Smart Grid since various information generators are connected to the internet. In this context, the electric power supply network has been used as "down load" only while Smart Grid will enable us to download and upload of the electricity for multiple directions as the information traffic flows on the internet.

An important difference from Internet, however, Smart Grid has to assure stable and continuous power supply without no delay. No "Best Effort" is allowed on Smart Grid.

Smart Grid sounds pretty smart and beautiful as written and pronounce. However a huge amount of new technologies and efforts for standardization will be required to build it on this planet. A small piece of information released by National Institute of Advanced Industrial Science and Technology (AIST) has driven me to think of the new vision of power electric distribution network.

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 ...

Broad Range of UV LED Applications

By
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.  Source: Nitride Semiconductors

Thanks All for Kind Notes Encouraging Japan Big Earthquake hit

By
We are receiving many emails, kind words and notes from outside of Japan.  Two typical messages say, " I do believe that your country people can overcome all the problems, above all, for Japan, the characteristic of your people is united & pursuit the best level all the time, where is valued to be respected." and " Japan is a strong and industrious nation, people would get through from such disasters  We believe it will recover soon.  Please accept our deepest sympathy and convey our best wishes to all of you" The magnitude of the earthquake that hit Japan has been reportedly the largest in the recorded history. No one can measure an overall impact to Japan society caused by the natural disaster at this point.  Finding more, the damages becomes bigger. We still are  in rescue and fact finding modes. However, i t’s for sure that the Japan society should be able to overcome the extraordinary difficulties, alt...
