3/25/2011   4 comments
Recently, the use of sensor networks has expanded into all sorts of applications to collect ambient or industrial data such as temperature, humidity, acceleration, pressure and any other relevant process information. Thanks to a new breed of microcontrollers that rely on partial circuitry activation or watchdogs to achieve power consumptions of only a few microamperes, battery size can be reduced or their operational life can be extended for a given size.

Fragmented frame buffer graphics ease cluster display requirements
Design How-To  
3/10/2011   6 comments
A new approach removes the need to store complete frame buffers in RAM, thereby reducing RAM size needed to support large displays. This method also allows images to be stored at an optimum resolution, thus reducing the non-volatile memory requirement as well.
Why you should use LXI instruments in your next T&M system
Test & Measurement Designline Blogs  
3/9/2011   Post a comment
Once, combining separate instruments into an integrated test system meant GPIB interfaces. Today, a world of interface options are available, including Universal Serial Bus (USB) and LAN eXtensions for Instrumentation (LXI). Although there’s definitely a role for USB in T&M system integration, from the perspective of a test system integrator, I think LXI offers an edge.
