We often handle things with our hands. Hand sizing is dispensable for designing easy-to-use products. HandMetrix consisting of a scanner and a PC is a system to automatically measure two-dimensional size and thickness of fingers and hand and finger joint circumference. Visit our booth and know your hand size.

Fluoride crystal and fluoride glass, doped with Pr³⁺ ion, are characterized by optical transition to red, orange, green and blue. With blue GaN semiconductive laser which has recently been developed for application to projectors, we have developed a multi-colored laser in visible wavelength range.

We will give you a summary of our latest study on a safe and reliable digital wireless communication system--high speed and large capacity for sure--that flexibly fulfills a wide variety of quality demands for personalization and customization of users' communication environment.

Our exhibition will be a position detection system using visible light communication technology and an optical LAN communication equipment. These systems have been developed through the study entrusted by the National Institute of Information and Communications Technology (NICT) as a part of the research and development of advanced communication and broadchasting technologies, by the collaborative group consisted of Mr. Masao Nakagawa, professor; Mr. Yoshinobu Matsumoto, assistant professor; Mr. Shinichiro Haruyama, professor; NEC; and Nakagawa Laboratories, Inc.

We propose Active Optical Network (ActiON) as the next generation access network to replace PON. Compared to PON, this new network enables to quadruplicate the number of users and double transmission distance by using optical switches. Our booth will introduce a data distribution system based on ActiON for different types of users and data contents.

In the cloud computing, high speed transmission of large volume data is vital. Our lab proposes a method, based on the SCTP parallel transmission, to prepare a large bandwidth path essential for large data transmission. Use of GMPLS allows anonymous selection of route to use for parallel transmission.

Our lab has carried out a study on the ubiquitous grid network, which provides new services when "something" such as camera and screen display is connected to the network, while simulating the next generation ubiquitous environment based on the optical broadband network to which a variety of things are connected.
