How a Power Switch Can Save the World Design How-To 6/30/2009 2 comments Nearly all electronic products contain a switch-mode power subsystem. To improve efficiency and cost throughout the life cycle of an application, many topologies and control methods have been tried. The latest-generation of power switches have changed the landscape by allowing integration as well as exceeding the new energy efficiency regulations that are becoming mandatory in the industry.
Climate bill spurs less green power than hoped News & Analysis 6/29/2009 Post a comment The renewable energy mandate in the climate change bill approved by the U.S. House of Representatives last week does not go far enough for green power proponents, but the proposed national standard is likely as strong as it will get.
Green pressure sensors tap quartz MEMS News & Analysis 6/29/2009 Post a comment Epson Toyocom unveiled a green sensor technology that eliminates dangerous oil and gases from pressure sensors, instead using a quartz microelectromechanical system (QMEMS) tuning fork as the sensing element.
Altera rolls low power, anti-tamper FPGAs Product News 6/29/2009 Post a comment Altera this week is rolling out a new product family, Cyclone III LS, billed by the company as the industry's first low power FPGAs with anti-tamper, design-security and design-separation features.
Industry agrees on unified cellphone chargers News & Analysis 6/29/2009 Post a comment The members of industry association Digitaleurope have signed a memorandum of understanding aiming at developing a common charging solution for mobile phones. The move dangles the availability of a charger that can be used across all almost brands.
Green shoots start to sprout in green sector News & Analysis 6/29/2009 Post a comment Canada's alternative energy sector is showing signs of a budding recovery, as companies resurrect financing deals and public offerings that withered with the recession, but that revival remains very fragile.
Q-Cells strengthens its CIGS leg News & Analysis 6/26/2009 Post a comment Solar cell manufacturer Q-Cells SE (Wolfen-Bitterfeld, Germany) has bought the remaining shares of thin film module manufacturer Solibro GmbH. With the move, Q-Cells emphasizes its commitment to the CIGS (Copper, Indium, Gallium, Sulphur/Selen) technology.
Electronic nose sniffs out cancer News & Analysis 6/25/2009 Post a comment Anecdotal evidence that dogs can detect cancer by smell inspired researchers to combine clever chemistry with optical detectors to craft an electronic nose that they claim can not only screen for any kind of cancer, but also determine whether it is aggressive.
XMOS foresees soaring sales, expects break even in 2010 News & Analysis 6/24/2009 Post a comment Startup XMOS Semiconductor Ltd. (Bristol, England), a vendor of event-driven processor chips, is enjoying a sales boom that will see the company move from shipping over 50,000 units a month at present to hundreds of thousands of units per month by the end of 2009, according to CEO James Foster.
Applying embedded design to develop an intelligent solar tracking system Design How-To 6/23/2009 4 comments Solar panels are typically in fixed positions. They're limited in their energy-harvesting ability because they cannot consistently take full advantage of maximum sunlight. For more effective solar energy systems, the solar panels should be able to align with sunlight as it changes during a given day and from season to season. This article examines the design advantages of creating an intelligent solar tracking system using an embedded processor and an FPGA in a system-on-a-chip (SOC) architectur
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
