China expands Internet censorship with new software
June 13, 2009 11:36 am | by Jason Lomberg, Technical Editor | CommentsAutocratic nations rarely feel the need to justify their actions. So China’s recent defense of its new internet filtering software was extraordinary. It also rings hollow. Starting July 1, the “Green Dam Youth Escort” software must be pre-installed on all computers sold within mainland China. The net-filtering software is aimed at protecting users from “harmful content.”
Brainstorm: New Product Development

Why MAX? – The purpose of WiMAX
June 2, 2009 9:40 am | by John Schwartz, Digi International | CommentsWhenever a new standard is adopted or starts to gain some ubiquity in the marketplace, I always have to ask, “So what? What does this new stuff give me that I don’t already have?” It’s an important question. If there is not any difference, then there is no reason not to just keep on using known and proven technologies. If there are differences, then knowing what these differences consist of can enable the appropriate business and design decisions.

Silicon Oscillators Offer EMI Improvements
June 1, 2009 10:50 am | by Greg Zimmer, Linear Technology, www.linear.com | CommentsOne of the most difficult electronics design challenge is to track down and eliminate electromagnetic interference (EMI). Switching regulators, a common source of EMI, continue growing in usage due to their space and efficiency advantages over linear regulators. For the designer, however, the EMI and associated regulatory requirements can present a significant challenge. To specifically address EMI in switching regulators, a multi-phase, spread-spectrum silicon oscillator is an appropriate solution.
Fathoming the future
June 1, 2009 10:31 am | by Alix Paultre, Editor in Chief | CommentsOnce upon a time, if you wanted to know the future you went to a colorful character who told you your fortune by examining bird guts, tea leaves, or other obscure random pattern generator. They were called witch doctors, clairvoyants, and fortune-tellers. Today we call them business analysts.

The new PICMG 2.30 Compact PCI PlusIO standard is based on PICMG 2.30 core specification and defines the migration path from parallel PCI to the serial PCI Express.
The Climate is Right for Wireless Environmental Sensors
May 21, 2009 2:39 pm | by Sol Jacobs, Tadiran Batteries, www.tadiran.com | CommentsThe effects of man-made climate change, once seen as a problem for future generations, is now viewed as an immediate threat, have led to significant technological investments to build a more sustainable future. From measuring the decline of snow packs in Antarctica and the North Pole, to measuring the impact of man-made dams on salmon migration patterns, to the development of systems that better predict natural disasters, remote wireless sensors are playing an increasingly critical role in advanced scientific technology.
Wireless ICs in Automotive Security Applications
May 18, 2009 1:01 pm | by Gilles Cerede, Melexis Technologies, www.melexis.com | CommentsLet's start with a tough question: What is the difference between TPMS system and PKE system? Nothing! A TPMS system is placed inside the wheel and composed of a sensing device that measures temperature and pressure. When appropriate, for example before starting the engine, the car requests a measurement through a wireless link. If a pressure default occurs in one of the wheels, the car warns the driver through a signal on the dashboard. In PKE applications, the user carries a key fob device which contains an encoded identifier (ID). When the driver enters their car, the car requests the key fob ID through the wireless link. If the ID matches the ID stored by the car,

Making lemonade
May 18, 2009 11:21 am | by Alix Paultre | CommentsThere's an old saying, "you can even get used to hanging, if you hang long enough". This industry has been on a rollercoaster for over a decade, between the Dot-Bomb, the Telecom collapse, the Internet, the housing bubble, the bank crisis, and disruptive technologies, we've been beaten about like a Pinata on Cinco de Mayo.
