Design Talk: Year in Review

December 8, 2009 9:31 am | Comments

When designing displays for mobile applications it’s often a balancing act between increasing ruggedization and keeping the product’s weight down.  These two seemingly opposite ideas can be solved by optically bonding substrates to the LCD front surface thereby eliminating the air gap which increases ruggedization without adding weight.

Optimizing Touch Panels for the Industrial Environment

December 2, 2009 4:33 am | by Bruce DeVisser, Fujitsu Components America, http://us.fujitsu.com/touchpanels/ | Comments

In the industrial environment, touch panels, or touchscreens, facilitate operator input in a very simple, yet reliable, way. As touch input-based handheld and mobile devices enter more industrial applications – such as portable flow controls and handheld terminals for field testing – companies need to protect and extend their investment.

Industrial-Strength Features Make a Difference in Embedded Processing

December 2, 2009 4:20 am | by David Katz and Rick Gentile, Analog Devices, Inc. | Comments

Many general-purpose signal processors are acceptable for industrial applications based on their computing performance and baseline connectivity features. However, there are important peripheral enhancements that can significantly upgrade the processor’s capabilities for more demanding industrial systems.

Cool stuff for Christmas

December 1, 2009 4:54 am | Comments

Holidays in New York City are beautiful. The lights, the people, the excitement. However, Christmastime in the city is also a constant reminder that you have gifts to buy for people, regardless of your particular secular rationale. For the style-conscious, the E Ink Digital Calendar Watch from Phosphor is both attractive and cutting-edge...

Man Pleads Guilty to Selling Fake Chips to US Navy

November 30, 2009 5:55 am | Comments

A 32-year-old California man has pleaded guilty to charges that he sold thousands of counterfeit chips to the U.S. Navy. In a plea agreement reached on Friday, Neil Felahy of Newport Coast, California, pleaded guilty to conspiracy and counterfeit-goods trafficking for his role in an alleged chip-counterfeiting scam that ran between 2007 and 2009. Felahy, his wife Marwah Felahy, and her brother Mustafa Abdul Aljaff operated several microchip brokerage companies that imported chips from Shenzhen, in China's Guangdong province.

Researchers find Reliable, Mess-free way to Grow Graphene

November 30, 2009 5:52 am | by Anne Ju | Comments

Single layers of carbon atoms, called graphene sheets, are lightweight, strong, electrically semi-conducting -- and notoriously difficult and expensive to make. Now, a Cornell research team has invented a simple way to make graphene electrical devices by growing the graphene directly onto a silicon wafer.

The State of the Budget ’Scope Market

November 23, 2009 9:21 am | by André Rebelo, Global PR Manager, Extech Instruments Corporation | Comments

After digital multimeters, oscilloscopes are the second most common test and measurement instrument used today. Within the spectrum of available benchtop, hand-held, and PC-based scopes, different needs can dictate what the best form factor is for one’s applications. Still, today’s scopes continue to surprise with features not previously found in their category...
