Not satisfied with the pictures you get with your 35-mm camera? Now there is a software program that lets you fix the pictures that don't capture all the visual quality and color intensity that your eyes see. The software is based on Retinax Image Processing—technology originally developed for remote sensing of the Earth by researchers at NASA's Langley Research Center and at Science and Technology Corp. "Current technology like that found in Adobe's PhotoShop software makes adjustments in gain, contrast, and other variables," says Glenn Woodell, an engineering technician and co-inventor of image processing software. "The difference with ours is that we not only look at the pixel, we also look at pixels around a given pixel." Woodell also says that colors are context dependent. "A given color, say green, surrounded by blue will look different than that same green when it is surrounded by red," he says. The software automatically makes corrections, but also allows manipulation of the image by the end user. The inventors—Woodell, Dan Jobson, and Zia ur Rahman—believe that existing image enhancement tools are either too tedious or insufficiently powerful compared to theirs. The software is currently licensed to TruView Imaging Co. "We think there are applications for the software in medical imaging, forensics, security, recognizance, mining, assembly, and many other industrial applications," says Rahman, who works for TruView. The company will make a software product available for home, professional, and industrial use by the end of the year.

The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
