How the DEA gets its cell phone data fix

October 3, 2013 9:55 am | by Chris Warner, Executive Editor | Comments

In the early 1980s, the old, pre-Cingular AT&T came out with an ad campaign urging us to "reach out and touch someone” to market its long distance products. It seems that today’s AT&T has been helping the government access its enormous database of phone records – dating back 26 years with 4 billion call records being added everyday....

E-Meters turn to smart relay drivers for remote grid management

September 26, 2013 4:20 pm | by Chris Warner, Executive Editor | Comments

Smart meters have been touted to consumers as being integral in helping them lower their utility bills. Armed with accurate information – such as consumption pertaining to specific times of day – consumers can then adjust their behaviors to shrink their bills and their carbon emissions and, if regulations allow, even select from different pricing structures....

Power plants and water treatment facilities diagnose motor problems without highly trained personnel

September 17, 2013 4:58 pm | by Jacob Beck, Electrom Instruments | Comments

The electronic devices used to test and analyze electric motors and other equipment have become much more powerful than in the past. Yet, in many instances these sophisticated devices have also introduced a high degree of complexity for users, requiring that highly trained and experienced personnel perform the testing.

Everything you need to know about picking the right circuit protection

September 11, 2013 3:33 pm | by M. Simon, Technical Contributor | Comments

When it comes to circuit protection, the first line of resistance is resistance. Resistance limits current flow and resistance, in conjunction with capacitance, slows the rate of increase of voltage, giving other protection measures in the circuit time to act. But, resistance has its drawbacks. If the current through the resistance is significant, it wastes power....

Fighting an invisible enemy: How UV robots are clearing the way for germ-free hospitals

September 11, 2013 2:17 pm | by Kasey Panetta, Managing Editor | Comments

Though medical devices are always moving towards less invasive, more effective technology, they face a constant, persistent and ever-evolving enemy in deadly bacteria and infections. Healthcare-associated infections (HAIs) can be caused by any infectious agent and result in 99,0000 deaths per year, according to the Centers for Disease Control and Prevention.

Adding a personal touch to automotive interior lighting via LIN

September 10, 2013 3:59 pm | by Michael Bender, Melexis | Melexis | Comments

Solid-state lighting is now becoming commonplace in automotive designs, replacing more costly, less energy efficient and not as reliable incandescent lamps. Though it is only in recent times that it has started to be considered for the parking lights, brake lights, side lights and front lights on the car’s exterior...

How to design backlights for LCD TV displays with scrolling LEDs

September 9, 2013 5:42 pm | by Girish Ramesh, Sr. Marketing Manager, Atmel Corporation and Kevin Hempson, Staff Applications Engineer, Atmel Corporation | Comments

You can improve contrast and reduce motion blur by sequentially flashing zones in an LCD display that is back lit with edge-mounted LEDs. You achieve this scrolling illumination with improved LED driver ICs. With the help of some timing diagrams this article will reveal how this works in principle and will give a description of the different modes of operation.

Battery harvesting versus energy harvesting

August 6, 2013 3:06 pm | by M. Simon, Technical Contributor | Comments

Should you use primary batteries or energy harvesting for your low power isolated from the grid application? Are primary batteries better or worse than energy harvesting? Can you use one or the other or do you need both? Neither? It is an interesting question depending on the application, the power required, and the costs involved.

Making aviation history: A solar-powered plane

August 6, 2013 2:01 pm | by Kasey Panetta, Managing Editor | Comments

While most of the country is still struggling with the concept of solar power on land, one team was busy using the panels to power something a little more ambitious: a plane. The program, called Solar Impulse, is devoted to designing a plane powered entirely by solar panels, in hopes of demonstrating the potential of alternative energy.
