Cover Story
- Battery management included
All the features and functions you design into your portable product do not mean a thing when the batteries lose their zing. Before your chips are down, consider the little charge-control devices that can help keep your products going...and going...and going...
Design Features
- Two PC buses go for round two
USB and 1394 are vying for "port space" on your PC and peripherals. - Digital audio gets an audition: Part two: lossy compression
Lossless compression can shrink file sizes down a fair amount, but for serious weight loss, you need to permanently discard some of the data. Find out how the lossy codecs work and whether you can hear the differences between them.

How It Works
- Electronics may be poised to displace engine cams
Software-based control may replace mechanical cams that control internal combustion-engine valves, but potential roadblocks remain.
Tech Trends
- In developing measurement applications, mixing metaphors minimizes
muddles
Using both textual and graphical approaches to develop an application can boost software developers' productivity. New tools just might end the wasteful "religious wars" that have plagued the programming profession.
