Crew remembers Apollo 11, looks to the future News & Analysis 7/20/2009 Post a comment The crew of Apollo 11 observed the 40th anniversary of the first moon landing by remembering those who helped them reach that historic goal. They also challenged future generations to go to the stars while caring for a "fragile" Earth.
How to design a low power wireless sensor network Design How-To 7/17/2009 Post a comment Driven by the demand for "green" technology and better use of power, a new generation of extreme low power wireless networks is being developed for use in machine to machine networks. With this in mind, a new approach towards truly wireless networks is needed.
When good grounds turn bad--isolate! Design How-To 7/17/2009 Post a comment
To make designers aware of these design pitfalls, this article explains where ground potential differences originate in the electrical installation, how ground loops are created unintentionally, and how isolation circumvents both conditions to yield a robust data-transmission system.
Deinterlacing with FPGA for HDTVs Design How-To 7/15/2009 2 comments Interlaced video is a succession of 50 or 60 fields per second, where each field carries only half of the rows that are displayed in each frame of video. This article explores different deinterlacing techniques and examines how FPGAs are increasingly being used for complex deinterlacing functions required for HDTVS.
