Select the right power system to optimize availability and efficiency needs

July 16, 2013 10:34 am | by Peter Panfil, Emerson Network Power, www.emersonnetworkpower.com | Comments

When it comes to power system design, there are many options to consider that affect efficiency, availability and scalability. In most cases availability and scalability are the primary considerations for data centers. The data center is directly dependent on the critical power system, and electrical disturbances can have disastrous consequences....

Non-contact infrared temp sensors monitor heat sinks and pipes

July 15, 2013 9:13 am | by Vasco Polyzoev, Systems Engineer, Texas Instruments | Texas Instruments | Comments

Measuring temperatures using infrared (IR) sensors without direct contact with an object, is the new paradigm in optimizing thermal monitoring and control. In this article we introduce the idea of this approach by taking advantage of new and very small IR temperature sensors available on the market.

The role of sensors in stable HVAC systems: Heavy duty pressure transducers

July 15, 2013 9:05 am | by Ketan Mehta, Honeywell | Honeywell Sensing And Control | Comments

Whether it’s a high-rise office tower or a manufacturing floor, Heating, Ventilation and Air Conditioning (HVAC) systems are designed for building occupants’ comfort. When systems operate at optimum levels, they’re energy efficient and go unnoticed. When they’re not, efficiency drops and complaints rise.

The government has been helping itself to our personal data all along

July 11, 2013 5:03 pm | by Chris Warner, Executive Editor | Comments

In the last few months I’ve been writing about various efforts of the government – both on the local and federal level – to leverage our consumer technologies to learn about our driving habits, cellular records, and, in the event of cyber attack, access to email records. Taken in totality, one could be highly suspicious that virtually anything and everything about our lives is accessible....

A tale of two cities: Ethernet meets PCIe

July 10, 2013 4:28 pm | by Michael Zimmerman, vice president of marketing, Tilera Corporation | Comments

Two industry megatrends are reshaping the way we design and deploy networks and compute (i.e. datacenter servers). The first is Network Functions Virtualization (NFV) with the goal of moving functions such as content distribution, firewalls and base station controllers from proprietary hardware to standard, low cost servers.

Self-healing circuits: A living immune system for ICs

July 10, 2013 4:08 pm | by Kasey Panetta, Managing Editor | Comments

One of the challenges of working with integrated circuits is as designers try to make ICs faster, the transistors become smaller and can’t handle as much voltage and the amount of variation grows. Plus, a single fault in the IC could mean a useless chip, bringing projects and products to sudden jarring halt.

Developing COTS systems to replace legacy systems

June 21, 2013 1:44 pm | by Michael Carter, CEO, Sabtech | Comments

A driving force in the current military environment is to keep legacy equipment operating longer or replace legacy systems with new ones that simulate or emulate one or more legacy systems.  Replacements face the challenge of interfacing with disparate communication protocols and interfaces.

Touch screens for medical instruments

June 21, 2013 8:48 am | by Eric Hawkins, Design Engineering Services, FocusLCD.com | Comments

The popularity of touch screen technology, also referred to as ‘touch panel’ or ‘user interfaces’, has increased a great deal in the last few years. Integrating interfaces with LCD is becoming increasingly popular. It is estimated that touch screen revenue will reach $16 billion in 2012, and nearly double in six years, reaching $31.9 billion by 2018.

3D printing is the future of the military

June 20, 2013 3:47 pm | by Kasey Panetta, Managing Editor | Comments

Aside from offering up the world’s least-appetizing pizza (protein cheese layer anyone?) and a way to eliminate illegal poaching, 3D printing might play a vital role in the future of the military. Though the technology is not nearly advanced enough to make a significant impact right now, the Navy is looking to 3D printing as a potential money saver for the future, according to an article published in the Armed Forces Journal.

A smarter way to toughen up military high-tech

June 20, 2013 12:58 pm | by Bruno Chaigneau, Application Engineer, Parker Chomerics | Comments

Procuring military equipment has become an extremely difficult task. Not only is there constant pressure to reduce expenditure, but performance requirements are increasingly hard to define as armed forces face growing and unpredictable threats such as civilian groups and militias using improvised weapons and ad hoc methods.

Enclosures for harsh environments ... they might surprise you

June 13, 2013 4:38 pm | by A.D. Horn, Rittal Corporation, www.rittal.us | Comments

The usual response to the idea of a “harsh environment” is to envision the salt spray of a drilling rig, dirt, grease or debris. But in today’s evolving world of “high tech,” the definition of harsh isn’t always what it used to be. An environment most people would consider far from harsh, almost sterile, can be extremely susceptible to contamination....
