CPV technology today and tomorrow

November 27, 2013 1:25 pm | by Anco S. Blazev | Comments

Modern CPV equipment consists of a metal pedestal cemented into the ground onto which a large metal frame is mounted on pivoting supports thus enabling it to move on an x-y axis with the help of a gear-drive assembly. Many CPV modules, mounted on the frame, contain a dozen or more highly efficient multi-junction interconnected CPV cells....

Bridge devices translate into longer life for NTDS systems

November 27, 2013 10:20 am | by Chris Warner, ECN Executive Editor | Comments

“It’s like turning around an aircraft carrier.” This analogy is often used in the business world to indicate how hard it can take a large entity to change direction, usually amounting to months or even years. But for the United States Navy, which is charged with turning these massive vessels, turning around an aircraft carrier pales in comparison with keeping communications networks up to date.

Protecting industrial PCs: Early discovery and containment with CIFS monitoring

November 26, 2013 1:59 pm | by Dan Schaffer, Phoenix Contact | Comments

A large number of legacy industrial PCs (IPCs) are still deployed in active control and monitoring roles. Most of these IPCs are running older, out-of-support operating systems such as Windows 2000 or XP. Microsoft Windows 2000 support expired July 2010, and Windows XP support ends April 2014.

What’s the best technique for temperature management of sensitive components in extreme environments?

November 22, 2013 4:33 pm | Comments

When it comes to environmental monitoring, most designers focus on temperature sensing for which there are a multitude of options. Few designers consider the benefits of including relative humidity (RH) sensing in their systems, which can be added to temperature sensing solutions without compromising board space and at very little additional cost.

The pogo alternative

November 20, 2013 2:04 pm | by Frank Folmsbee, Sales Manager at Aries Engineering | Comments

For many years the most effective test socket contact design for BGA devices was the "pogo pin", a pin design that has been in use since the 1950s when it was invented by Everett Charles Technologies. At that time, its primary use was to test PWBs. Over the years the basic pogo design was adapted to accommodate the testing of BGA devices.
