Finally, Power Supply also Goes Wireless
If electric power were able to be transmitted without wires, we could drastically reduce such annoying tasks as recharging with a charger or changing batteries. In some cases, power cords could become redundant. By achieving high-power transmission, we have come within reach of application in a wide range of handheld terminals and mobile devices.

3D, Animation and Translucency to Make Device Navigation More Colorful
The scene is now set for fun-to-use interfaces to be built into a broad range of devices. Soon it will become much easier to add color to expression using 3D graphics, animation and transparent windows. Such interfaces are likely to spread, starting with PCs and gradually moving to digital consumer electronics and Internet-based services.

MCMs for DC-DC Converters
The maximum current consumption of server microprocessors has surpassed 100A and has reached several tens of amps in field programmable gate arrays (FPGA) and application-specific integrated circuits (ASIC) for communications devices. The general view is that current consumption will keep on rising. Meanwhile, the amount of space on PCBs allocated to DC-DC converters, which provide the power, is already approaching its limits, meaning they have to be both compact and able to output a large current. This article looks at multi-chip modules (MCM) for DC-DC converters—the trump card needed to satisfy such conflicting requirements. We compare the products available, focusing on MCMs for DC-DC converters, mainly with input voltage 10V or higher, powering LSI that require large currents. (Satoshi Okubo)

The Golden Age of Software Architecture
The process of developing software systems requires decisions to be made on a wide range of design matters. Some decisions influence a system’s basic configuration and consequently have a major impact on its performance and reliability. “Software architecture” picks up on those areas that are common to the majority of systems. Software architecture remains hard to define, yet after first drawing attention in the mid 1980s, it has grown in substance through a number of steps, tools and environments have been developed, and the discipline now fills an essential role in complicated software development. This translation of a paper from US periodical, IEEE Software, analyzes the trajectory of software architecture’s growth using a six-stage software technology maturation model, the “Redwine-Riddle Model.” The authors say that software architecture is in its golden age and in the near future will solidify its standing as a genuinely successful software technology.

Reflecting on the Development of the Prius, the Byword for an Environmental Brand
The Prius hybrid vehicle developed by Toyota Motor Corp. is often talked about as typifying the products that helped raise the company’s environmental image. An engineer who worked on development of the Prius at Toyota for 13 years looks back on that process. The project is likely to be viewed as a model case for groundbreaking product development.

What NTT DoCoMo Thinks about the Evolution of the Mobile Phone (Part 3)
Standardization activities for fourth-generation (4G) mobile phones are about to move into full swing. In autumn 2007, a meeting will be held to determine wireless frequency bands and afterwards deliberation on technical specifications will be advanced by the International Telecommunication Union (ITU). In the final installment of this three-part series, we learn about 4G concepts and the various initiatives of NTT DoCoMo, Inc.

Players in the communications industry are portraying a smooth and gradual transition. The second installment in this three-part series provides an overview of Super 3G communications technology that will form a link between 3G and 4G.
Interview
Waseda University Global Information and Telecommunication Institute, Vice Director, Takuro Sato: “It’s a Wireless LAN that Is a Little Different from Others”
Venture company Key Stream Corp. is grabbing a lot of attention in the world of wireless LAN integrated circuits (IC), with its products employed in devices such as Microsoft Corp.’s “Zune” portable music player and various brands of IP phone terminals. The company is steadily moving forward with preparations to develop next-generation ICs; early in 2007 Renesas Technology Corp. took a stake in the enterprise. Key Stream was founded in December 2000 by Waseda University Graduate School professor, Takuro Sato. At the time, he was teaching at the Niigata Institute of Technology and had to work hard to get his venture firm up and running.
