The article features a film-based, a bendable material from Fujitsu Ltd. and Fujitsu Laboratories Ltd., that displays text and color images and consumes no power when displaying them. Fujitsu officials say that the power to change an image is so low that the weak radio frequency energy in contactless integrated circuit cards can deliver that energy to the device. The substrate material has three layers and delivers more vivid images than do standard reflective liquid crystal displays, because the material uses no color filters or polarizing layers.

This article presents a case study that deals with the handling of a DC bulk power problem through the iCool™ voltage regulator module (VRM) connector. Early test data of this new VRM connector concept was well received with potential customers, but they also pointed out two problems. The prototype had retained the insert and rotate latching approach typical of single in-line memory module connectors, which occasionally prevented the VRM from being located in the best position on the motherboard. Either the chassis walls or the processor heat sink prevented module insertion to the connector. A second issue found that VRM designers required a module PCB of 0.062. With no methodology existing, Molex developed a procedure to demonstrate the reliability since this could be a showstopper if not proven. The comprehensive solution has been well documented in a paper written by Dr. Bob Malucci of Molex titled Current Rating for Multi-Path Power Module Connectors. Basically, Molex took the approach of combining actual end-of-life environmental contact resistance data with actual current temperature rise data in a random yet statistically significant predictive methodology.

This paper deals with the skepticism surrounding the Worldwide Interface for Microwave Access (WiMax) in 2005. WiMax is a metropolitan-area-network technology that fits between wireless local area networks, such as 802.11, and wireless wide area networks, such as the cellular networks. Bandwidth generally diminishes as range increases across these classes of networks. WiMax, proponents, however, do not believe that a nationwide rollout in the U.S. is a prerequisite for success. Many developing nations have no entrenched wired infrastructure and no plans to dig ditches and install one. The less-than-$100 price point is precisely what Intel hopes to enable with its Rosedale chip, according to Joe English, director of marketing for the Broadband Wireless Division of Intel. According to English, the Rosedale design focused on low-cost customer-premises equipment, whereas other WiMax chip developments target enterprise or base-station applications, as well. With programmability as a requirement, one would also expect field programmable gate arrays to be players in the WiMax base-station space. But, Asif Batada, strategic marketing manager for Altera's wireless business unit, claims that the bulk of the interest he is seeing is for the still-under-development 802.16e standard or mobile flavor of WiMax. Part of the negative aura has come from grumbling about the WiMax Forum's certification process. The wild card in the mobile-WiMax equation is how the technology aligns with cellular technologies.

This paper features the PM0402T and PM0603T chip inductors from JW Miller. Magnetics measure 1x0.5x0.35 millimeter and 1.5x0.8x0.45 millimeter, respectively. These inductors, fabricated with photolithographic-design techniques, have tolerance of ±two percent and are available in one to 68 nH at 100 megahertz, typical charge at 300 megahertz is 17. Minimum self-resonant frequency is six gigahertz, and the devices can handle maximum direct currents of 70 to 800 milliamperes depending on nominal inductance value. The PM0402T and PM0603T inductors sell for 11 cents and 18 cents, respectively.
