November 7, 2012 1:37 pm | by the Editors | CommentsThe 25th International Trade Fair for Electronic Components, Systems, and Applications (i.e., electronica 2012) starts next week (or now, depending on when you see this), so ECN thought it fitting to interview one of the leading OEM vendors, Standex Electronics about industry trends, especially as it relates to sensors.
Is glasses-free 3D ready for industrial/medical applications?
November 6, 2012 4:36 pm | by Dale Maunu, Senior Business Planning Analyst, Renesas Electronics America | CommentsHarking back to the good-old-days, before social media, before texting, before mobile phones – all the way back to when we (not me literally) received news from the wireless (radio), this new-fangled invention came along called the TV and sat down in living rooms everywhere.
Do ultracapacitors make wind energy a sustainable option?
November 5, 2012 12:27 pm | by Kasey Panetta, Associate Editor | CommentsThe idea of using wind to create energy isn’t exactly new. The first examples can be traced back to 200 B.C. in Persia – a creation of Heron of Alexandria. That particular device simply harnessed the wind to power a machine, so a case could be made that the first real windmills were built a little bit later, in the 7th century in Sistan, modern day Iran.
Machine to machine communications – The Facebook of smart devices
November 5, 2012 11:21 am | by Ramanuja Konreddy, Senior Product Marketing Engineer, MCU32 Division, Microchip Technology | CommentsImagine a bike that sends its location to your smart phone if moved; a camera that can talk to a GPS module and suggest scenic locales when you are on a hike; a refrigerator that would send you a reminder text message when the milk runs out; a smart meter that can turn on your washing machine during off-peak hours...
How to use off-the-shelf DC-DC converters for backlight applications
November 2, 2012 3:13 pm | by David Smith, Sr. Field Applications Engineer, Seiko Instruments | CommentsIt has become increasingly more common in portable, handheld devices to use white backlighting for display illumination. The use of white LEDs, are practical in mobile applications due to the need for color reproduction and balancing. For a low cost, simple alternative, an inductive-based DC-DC converter can be used...
Seeking solutions to color binning in the LED value chain
November 2, 2012 11:12 am | by Geoff Gardner, Marketing Manager, Dow Corning Lighting Solutions | CommentsThe semiconductor technology that underlies solid-state illumination represents the epitome of precision manufacturing. Production of these devices begins with creation of blue light-emitting diodes (LED chips) through the nanoscale deposition of semiconductor materials onto a wafer...
An optimized power factor-corrected driver for LED bulbs
November 2, 2012 10:08 am | by Bernie Weir and Frazier Pruett, ON Semiconductor, www.onsemi.com | CommentsAs incandescent bulbs are phased out, the two options that offer significant energy savings are compact fluorescent (CFL) and LED. While CFL’s are a mature technology, white LEDs are still advancing rapidly with higher lumens per packaged LED as well as increased efficacy.
