Carpe Diem: Install Insulated Roman Shades

March 17, 2010 1:22 pm | by Energy Savers Blog | Blogs | Comments

As I mentioned in yesterday's blog, I had insulated window quilts installed on most of my home's windows. I should have bought window quilts for all of our windows, but I refrained from doing so on two downstairs windows to save money (which, in the long run, I didn't). There were window...

New high-reliability contact system facilitates automated assembly

March 17, 2010 9:43 am | by Dave Humphreys, Product Manager, Harwin Inc | Articles | Comments

There are many applications whose operating environments demand the use of an interconnect system with a high-reliability contact. If equipment is to be used where high shock and vibration or extremes of temperature are experienced, connectors based on a standard contact will not be reliable or rugged enough to guarantee signal integrity.

Do gamers make better soldiers?

March 17, 2010 5:54 am | by Jason Lomberg, Technical Editor | Blogs | Comments

Findings by the Office of Naval Research indicate that video games improve overall perceptual and cognitive abilities. While nothing new—the claim is nearly as old as Pac-Man, the irregular warfare we face today makes it more relevant than ever. Since Pong, video games have been castigated for everything from school truancy, to school shootings, to even global warming.

Software Quality - What you don’t know CAN hurt you

March 15, 2010 11:16 am | Blogs | Comments

My point here is not to join the chorus of Toyota-bashers. Rather it is to point out that major software quality problems seem to be occurring with increasing frequency across more industries today – and they are definitely happening more frequently in the embedded industry. 

Static Power Path Management (SPPM) to Provide an Effective Handheld Battery Charger Solution

March 12, 2010 10:44 am | by Chuck Wong and Haitao Hu, Intersil Corporation | Articles | Comments

Handheld electronic devices -- regardless of what they are used for or who manufactures them -- share one common denominator: a re-chargeable battery and, in most cases, a built-in charger circuit. When an external power source such as an AC adapter or a USB port is attached at the input terminal, the charger circuit will re-charge the battery.

Design Tips Save MCU Power

March 11, 2010 4:11 am | by Jon Titus, Senior Technical Editor | Articles | Comments

Microcontrollers offer engineers a variety of power-saving techniques. But using them effectively requires careful attention to tradeoffs in software and hardware at the start of a project. "Engineers must partition their application so they have a rough idea how long their microcontroller will stay in a sleep mode or in an active mode," said Mike Salas...

Video games and the military: Engaging the “tech generation”

March 9, 2010 9:10 am | by Jason Lomberg, Technical Editor | Blogs | Comments

For good or ill, the military is often indistinguishable from a large corporation. While “employees” must conform to the company’s modus operandi, the company must engage its employees on their terms. In this day and age, that means technology. Thus, the military increasingly relies on video games and computers to recruit and train its “employees.”
