Urban Vegetable Garden System with LED Lighting

Keystone Technology's LED vegetable garden system is a cultivation system for indoor plant factories which uses LED lighting instead of sunlight. The most defining feature of the system on display at the company's showroom in Yokohama is its 3-dimensional use of space.

"This is a 5-tiered cultivation system. For smaller heads of lettuce, you can harvest about 1,500 heads in one month. If this were to be fit into a container of about 20 feet (6m), it would be equivalent to 970 sq. meters. Thus with 16 sq. meters, you could produce an amount that is on par with 970 sq. meters."

LED lighting has three different wavelengths of red, blue, and green. This system can control the illumination strength according to the stage of plant growth. So, cultivation that would require two and a half months with land cultivation can be reduced to less than one month of cultivation and harvesting.

"In most cases, lettuce grown indoors is crisper and does not have the coarse quality of lettuce grown in sunlight. Because it is softer, it is a vegetable that is easy to eat even for elderly people. Although this may be unexpected, as for the nutritional components or more accurately the functional ingredients, it is possible to obtain a larger content by percentage of vitamins and polyphenols than with vegetables grown in sunlight."

With this system, there will be differences in production capacity depending on the shape of the plant. Because plants with leaves that spread sideways take up more space, the number of such stalks that can be cultivated is reduced. On the other hand, plants that grow upwards can be planted with smaller intervals so a greater number of stalks can be cultivated.

"This plant factory itself has been here for over 20 years, but there is very little history of plants grown with LED lighting. In particular for plants grown with red, blue, and green lighting, the produce displayed at a plant factory exhibition in July 2010 was our company's first ever."

Commercially available since 2010, this system has been installed in various factories, offices and eateries nationwide, such as by a leading eating establishment that has installed 48 units in its processing factory in Kanagawa Prefecture. As workers in Japan's agricultural industry age, it is becoming more difficult to obtain safe and delicious vegetables through traditional farming techniques. Keystone Technology will continue to offer new lifestyle ideas that provide cities with production capacity and integrate consumption and production.

The Igarashi Lab. at the University of Tokyo is developing a new type of physics engine which can faithfully recreate in 3D the stylizations common to 2D anime.

"Physics engines are used in 3D animation, to generate the motions of hair and clothes. They can do physically correct computing, but the problem is, that's all they can do. The engine we've created makes it possible for artists to adjust such physics computations, in other words, to deform things."

SEL have developed a range of flexible OLED displays and high PPI LCD panels which use CAAC oxide semiconductors.

"CAAC stands for C-Axis Aligned Crystal. In this material's structure, the crystals are aligned in the c-axis direction. Because CAAC itself is crystalline instead of amorphous, it has much higher reliability. Until now, with oxide semiconductors, reliability was generally thought to be a problem, but using this material solves that problem."

 

At the University of Tokyo, the Hirose-Tanikawa Lab is doing R&D on a system that virtually creates and affects people's emotional states.

 

This mixed reality interface places virtual characters in the real world. It was developed by the Naemura Lab at the University of Tokyo.

Users can have an animated character jump onto their hand, as well as guide the character onto blocks, creating a novel interactive experience.

"Recently, devices have been developed that can form images in mid-air. We've utilized one of those, and combined it with sensors and a projector, to provide an intuitive display experience where a picture in the air is skillfully merged with the real world."

Fujitsu boosts security for multi-service palm-vein authentication system

Fujitsu Laboratories has developed a new identification technology, which enables palm-vein identification to be used securely in a wider range of situations.

Conventional palm-vein identification works by comparing complex vein patterns extracted from images of the user's palm. By contrast, Fujitsu's new technology extracts characteristic components from the vein patterns, and uses them to generate 2,048-bit reference codes which are used for comparison.

It is being developed by the Koike Lab. at the University of Electro-Communications.

 

The Hairlytop Interface is an interactive surface display made of soft solid-state actuators and optical sensors which react to light. Jointly developed by the University of Electro-Communications and Symphodia Phil, when placed on an iPad that is playing a video, it moves organically, like a living thing, in response to changes in the brightness of the screen.

"One feature of this system is that the motion is very cute, like that of an animal. Another feature is that it can be used extremely freely in terms of design."
