Re-inventing the Wheel... as a square Blog 4/20/2004 Post a comment We've all seen renderings of the disconnect between marketing, engineering and customers in product development - using a child's backyard swing as the example. "What marketing requested" shows a three-tiered swing, with cushions and lollypop dispensers. "What engineering came up with" shows a rocket-propelled platform, springing back-and-forth through a steel-reinforced tunnel. "What the customer really wanted," of course, was a truck tire hanging by a rope from a tree limb. This month, Sanjaya

UPSes step up in class Product News 4/4/2004 Post a comment FOCUS ON Backup Power - With power availability becoming crucial at even the most basic system level, low-end UPSes are increasingly carrying more of the same functionality seen in mission-critical supplies serving mid-range and higher-end applications. Indeed, the notion of a "graceful exit" from a small job during a power-down is much less accepted today. In contrast, the mostly off-line and line-interactive units used in these applications tend to carry more raw battery backup even if it take
