Invisibel speaker componet

A very thin component (2.4mm x 4.7mm x 34.5mm) is a distribute mode actuator which is made of piezoelectric thin films formed on metal plate. This device enables a flat panel screen to vibrate to make sounds. The flat display panel may vary from a mobile communications device to a desktop display system such as a personal computer. According to a news release from the supplier, Authentic, Ltd., the Authentic's DMA device is embedded in a mobile clinical assisting system of Philips FIMI.

I personally wish and expect that a further improved version of this device will be used when an organic electroluminescence display is commercially available some time in the near future.

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 ...

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.

Thanks All for Kind Notes Encouraging Japan Big Earthquake hit

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...
