This helmet lets fighter pilots ditch their night vision goggles

July 28, 2014 | by Chris Warner, Executive Editor | Comments

Military jobs are synonymous with stress, but one of the most stressful jobs even by military standards is that of the jet fighter pilot. Not only are they required to process a lot of operational information very quickly, they must do it while wearing headgear that can strain the head and neck the faster the plane flies....

This first-aid kit is a must-have

August 1, 2014 8:55 am | by Kasey Panetta, Managing Editor | Comments

The Clever Medkit is a first-aid kit to end all first-aid kits. This over-the-top technologically advanced kit is technically designed for businesses, but I would consider this for a home purchase because I am a germaphobe and hypochondriac. (Yesterday, I used a Lysol wipe on my pens.) So, let’s walk through the process of injuring yourself and using this bad boy.

Display glass chamfer: Complex design challenge or all-laser solution?

July 31, 2014 8:22 am | by Dr. Michael M. Mielke, Chief Scientist, Raydiance | Comments

Remember the Apple iPhone 5 video of Jony Ive describing his “diamond cut chamfered edges?” If you’re not a mechanical engineer, this may have been the first time you heard the term “chamfer.” It turns out that chamfers are critical design aspects of nearly all portable consumer devices, including smartphones and tablets....

The F-35 will cost a fortune

July 30, 2014 2:02 pm | by Jason Lomberg, Digital Editor | Comments

Captain Obvious? Is that you? I’m sure this comes as no surprise, but the F-35 Joint Strike Fighter is expensive. Very expensive. So expensive that, according to one estimate, the money spent on the program could buy every homeless person in the U.S. a $600,000 mansion....

July 25, 2014 11:29 am | by Karl Stephan, Consulting Engineer, Texas State University, San Marcos | Comments

Harvard and MIT have teamed to develop an artificial-intelligence system that grades essay questions on exams. The way it works is this.

Recently, Google/Nest, together with Samsung, ARM, Yale Security and others, announced a new standard “Thread”. Sort of. Thread is not really a new standard, but more of an education and certification program that combines a set of existing standards into a “single” package....

Efficiently Power that Op Amp

July 24, 2014 9:43 am | by Chris Glazer, Texas Instruments, www.ti.com | Texas Instruments | Comments

In many applications, such as temperature sensing, two supply voltages are needed to power an op amp in the system—one positive and one negative. This dual supply is needed by the amplifier in order to properly measure signals very close to or even below ground. If the negative supply input of the op amp was just grounded and a single, positive supply voltage used, these signals would not be processed properly.

Business at the expense of all else

July 22, 2014 12:38 pm | by Alan Nicol, Executive Member, AlanNicolSolutions | Comments

I would never want to believe that a business, operated by intelligent and moral people, could sacrifice quality, and even ethics, to produce a product and complete a sale. Yet recently, I witnessed a business that was so desperate to make a few deadlines, it bypassed due diligence to get a product delivered....

July 22, 2014 9:49 am | by Kasey Panetta, Managing Editor | Comments

In the midst of the Hobby Lobby court case decision and other conversations about birth control, there has been an announcement about an advancement in contraceptive technology. This is a pretty unique technology that would allow the woman to turn the device on or off, depending on if she was looking to have a child or not....

How to drive LEDs with power factor correction in a single stage

July 16, 2014 1:47 pm | by Brian King, Texas Instruments, www.ti.com | Texas Instruments | Comments

A PFC-SEPIC converter can be controlled using a traditional PFC-boost controller. An important characteristic of the SEPIC is the lack of isolation.  This limits the use of this topology to applications that don’t require safety isolation.  Think about applications that are completely sealed with no user-accessible energized parts, like street lights and high-bay lighting.

July 14, 2014 4:08 pm | by Chris Warner, Executive Editor | Comments

Forget about remembering to take a contraceptive pill. In just a few years, keeping track of your remote control may be as essential to family planning as it is to watching TV. MicroCHIPS, a small, Massachusetts company with backing from Bill Gates plans to bring an implantable contraceptive chip that can be turned on or off via remote control to market as early as...
