Update 29 July 2010: Listen to a podcast about the centrifuges with Eric Hoek, an engineering consultant for Ocean Therapy Solutions.

14 July 2010—After 85 days, the oil leak in the Gulf of Mexico is now partially contained, and relief wells to stem the flow are inching closer to completion. Once the leak is fixed, the focus will shift to removing the oil that’s already in the water. The actor Kevin Costner has appeared on TV and in front of the U.S. Congress to tout his oil cleanup machines, but can they actually make a dent in the still-spreading environmental disaster?

Nick Holonyak Jr., a prolific inventor and longtime professor of electrical engineering and computing, died on 17 September at the age of 93. In 1962, while working as a consulting scientist at General Electric’s Advanced Semiconductor Laboratory, he invented the first practical visible-spectrum LED. It is now used in light bulbs and lasers.

Holonyak left GE in 1963 to become a professor of electrical and computer engineering and researcher at his alma mater, the University of Illinois Urbana-Champaign. He retired from the university in 2013.

Exploring the Value of Power Modules

Learn how power modules can reduce power supply size, EMI, design time, and solution cost

1 min read
Texas Instruments

In this training series, we will discuss the high level of integration of DC/DC power modules and the significant implications that this has on power supply design.

Watch this free webinar now!

In addition to high power density and small solution size, modules can also simplify EMI mitigation and reduce power supply design time. And thanks to improved process and packaging technology, a power module may even provide all of these benefits with a lower overall solution cost as well.
