Keynote addresses by noted industry experts as Youngky Kim (EVP, New Generation System Technology & Products, Samsung), Jim Battaglia (VP, Strategic Business Development, Panasonic), and Fred Kitson (VP of Applications Research, Motorola).
Switch-Mode ICs Promote Efficient Power Management, Part 1: Switch-Mode Fundamentals
By Sam Davis, Contributing Editor
A switch-mode converter circuit uses a controlled power semiconductor switching technique along with an inductor, transformer, or capacitor as an energy-storage element to transfer dc power from its input to its output. In a basic switch-mode converter, a dc-to-pulse-width converter IC accepts a dc input and produces square waves applied to a power semiconductor switch.
Home theater PCs aren’t new. But getting one that works, especially with HDTVs and HDMI, is now a lot easier with AMD’s Maui AMD Live! This platform is designed for Microsoft Vista Media Center and AMD Athlon processors.
There are hundreds of versions of Linux, including embedded-specific distributions like TimeSys, MontaVista, and Wind River Linux, and well-known desktop/server distributions such as Red Hat’s Enterprise Linux and Novell’s SUSE.
As the demand for bandwidth and high-speed transport grows, so does the use of fiber-optic based transport. One of the enabling technologies associated with optical transport are Fiber Bragg gratings (FBGs). This tutorial will introduce the concept of FBGs and describe the advantages provided by use of FBGs for chromatic dispersion compensation.
Noise in low-level measurements can come from a number of different sources, including motors, office machines, power demands, and the switching supplies found in office equipment. Learn tips on what features to look for in the power supply, and how to minimize the noise in your test setup.

10-GHz Divide-By-100 Prescaler Connects To 100-MHz Counter
By Wayne Ryder, SRI International
The prescaler described here connects to the front end of a 100-MHz frequency counter to extend its coverage range to 10 GHz. The circuit is a far less expensive way to measure frequencies above 100 MHz than buying a 1- or 10-GHz frequency counter.
Big Stage Entertainment recently launched BigStage.com, a Web site where anyone can create a free, animated 3D "Digital Youâ€쳌 for instant projection into the online landscape.
USB is ubiquitous, but it’s usually used to connect boxes like PCs and laptops to other devices. The type of USB hosts are changing already, with USB sockets on printers and even HDTVs providing access to USB flash drives. Playing a hi-def movie from a flash drive is no longer a goal but a reality. But USB inside the box is a much different story.
The .NET Micro Framework is a platform that enables developers to more quickly develop embedded systems that are smart, securely connected and easier to manage. Jonathan Kagle, Microsoft's .NET Micro Framework Senior Program Manager, introduces us to some of the hardware developers are using in Micro Framework devices, including entries from SJJ Embedded Micro Solutions, Crossbow, GHI Electronics, Atmel, and Digi International.
BASF and OSRAM have created the first organic LED (OLED) to achieve a light yield of more than 60 lumens/W while also meeting the international Energy Star SSL Standard for color requirements.

Optically Isolated Sigma-Delta Modulator Fortifies Industrial Motor Designs
Announced as one of the industry’s first optically isolated sigma-delta modulators using an external clock to provide direct measurement of motor phase currents in power inverters, the CMOS-based ACPL-796J uses an external clock that allows synchronized data conversion between the current sensor and controller.
