Auld Lang Syne
December 23, 2008 12:06 pm | by Alix Paultre, Editor-in-Chief | Articles | CommentsAs we head into the New Year, looking towards the future, our minds are always drawn to the past. “Auld Lang Syne” means roughly ‘long times past”. Our ruminations on the past vary from individual to individual; one may look back nostalgic, another regretful, and the third satisfied. The most important thing to remember is that the past is past, and we must embrace the future or face the consequences.

Embedded Systems: Ethernet Modules Act Like SBCs
December 23, 2008 8:45 am | by Jon Titus, Senior Technical Editor | Articles | CommentsManufacturers offer a variety of small modules that let engineers easily add an Ethernet port to a design. They may need only a UART or I2C port in a main system to communicate with and control one of these modules. But if engineers stop there they will miss many other capabilities offered by these modules--actually single-board computers (SBCs).

Industry Focus: Planning for End-of-Life in Mil-Aero Markets
December 23, 2008 6:06 am | by George Karalias, Rochester Electronics, LLC | Articles | CommentsAlthough the ramifications of end of life (EOL) announcements have long been an issue for OEMs in the mil/aero marketplace, many still fail to put a workable plan in place to face this reality. As a result of the increase in end-product programs for these industries, long-term support requirements can sometimes extend for decades, leaving customers in a difficult position as they source components for ongoing production, maintenance and repair.
FPGAs Offer More Flexible, Affordable Embedded System Solutions
December 23, 2008 5:51 am | by Stephen Cunha, MEN Micro, Inc. | Articles | CommentsPotential solutions for providing application-specific functionality in embedded systems typically come with trade-offs in terms of cost and time to market. With few projects having the lead-time, budget or high-volume payback potential to tool-up for custom chip or hardware production runs, the best answers often revolve around "modular" solutions.

Semiconductor Highlight: ZigBee Radios and ICs Gain Momentum in Industrial Control Applications
December 23, 2008 4:52 am | by Rich Howell, California Eastern Laboratories | Articles | CommentsRiding an elevator is typically a mundane exercise - you push a button, you wait, you get off at your floor. Few give any thought to the workings outside the metal box you’re riding. But behind the scenes a lot of technical communication takes place between the elevator car, the controller at the top of the elevator shaft, and the call button you’re patiently pushing in the lobby. Today that communication is typically conducted over high-grade RS-485 twisted pair serial cable.
