In designing an LED lighting application, it is imperative for engineers to consider certain factors in their blueprint. Obvious considerations including lumen output, CRI, system efficacy, size, weight, and cost may be discussed at length, but a suitable cooling solution may be overlooked.
LED lighting provides both promise and challenges for virtually every electric lighting application currently served by earlier illumination technologies such as incandescent and fluorescent lighting. Indeed, the U.S. Department of Energy (DOE) has proclaimed that no other lighting technology offers so much potential to save energy over traditional lighting technologies.
As heat loads continue to escalate in electronic equipment, designers seek out more powerful heat sinks to cool their electronic devices. In many instances, designers are turning to pin fin heat sinks, which are considered to be one of the most effective heat sink technologies available.
Simple, low-cost I/O is important. You might say that trying to hang a relay, UART, or other low-speed device on a PCI Express lane is like trying to get a drink of water out of a fire hose! So how do you handle I/O on the chips?
Google has shocked the world by ending its Chinese censorship operation. Due to numerous factors (including cyber attacks emanating from China), Google declared that it’d no longer censor search results on Google.cn. Since launching Google.cn in 2006, Google has reluctantly accommodated China’s despotic online censorship.
New devices, technologies, and development kits make it easier than ever to include haptic controls in a design. Here's an overview of several hardware and software advancements. Atmel's first maXTouch touch-sensor controller and microcontroller, the mXT224, gives equipment designers as many as 224 sensing nodes across display screens than can exceed 10 inches.
Like the Goths sacking Rome, the 3-D invasion has arrived. No longer a kitschy gimmick, the technology has matured, and the leading consumer manufacturers are banking on it. Indeed, 3-D was the unofficial theme of CES 2010—3-D demos littered the show floor, and all the big players (with notable exceptions) unveiled 3-D products. Could 2010 be the year that 3-D finally takes off?
In the world of science, it is a universally accepted premise that a ‘Scientific Fact’ is something which can be proven at any time, in any place, and by anyone with sufficient scientific knowledge. At the turn of the millennium, we started to hear about Global Warming Greenhouse Gases (GWGG).
In September the Venturi Buckeye Bullet 2(BB2) became the first hydrogen fuel-cell vehicle to eclipse the 300 MPH mark, setting an international speed record of 302.877 MPH, making the BB2 the fastest hydrogen powered vehicle in the world, including those using hydrogen combustion engines.
OSU has earned top honors at the 2009 finals of the Year One EcoCar competition. The OSU stable bested 16 other teams with their “Extended Range Electric Vehicle” design.
Rep. Linda Sanchez (D-CA) has introduced a bill designed to combat "cyberbullying.” And in a rare instance of bipartisan solidarity, the left and the right stand opposed. Make no bones about it—the proposed legislation is a serious assault on first amendment rights.
Global investments in renewable energy technology dipped 40% from 2008-09—this according to United Nations Industrial Development Organization Director, General Kandeh Yumkella. “Due to the current economic crisis we have seen almost a 40 percent decline in 2009 alone in these investments,” said Yumkella...
Back in March, we reported on the California Energy Commission’s proposal to set a cap on the maximum active mode power usage (watts) for TV’s. All units above the maximum would be banned for sale in California—this would preclude the vast majority of Plasma, DLP, and Rear-projection TV’s.
Way, way, way too much is being made of the supposed impact Intel's new Atom N450 chip will have on the netbook and, by extension, laptop markets.
This month's question, "What is the biggest challenge facing the adoption of multicore processors by the engineering community for more applications?" was answered by people from Texas Instruments, Freescale, The Mathworks, and National Instruments.
