In order to see how ultracapacitors make battery modules greener, one needs to have a basic description of the devices. Batteries rely on a chemical reaction to dissipate stored energy. There is no chemical reaction in ultracapacitors, as they store energy in an electrostatic field.
Small-size and low-cost netbooks, ultra-mobile PCs (UMPC) and mobile internet devices (MIDs) are becoming more popular and gaining wide user acceptance. The Lithium-Ion (Li-Ion) battery charging system used in these portable devices is much more sophisticated than that used in cellular phones.
Today’s high-performance processors for networking applications utilize a multi-core approach that benefits from packet and flow level parallelism inherent to network processing. Multicores optimized for networking applications typically augment general-purpose processor cores...
Automotive applications are becoming more sophisticated as different in-vehicle systems are networked together to share information, monitor performance and enhance safety. In addition to growing more complex, automotive systems demand more cost-efficient electronic components with smaller footprints for space-constrained applications.
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.
Designing a buck converter isn’t easy. Most users want a box that works—taking in one DC voltage and delivering another. This box can take various forms. It can be a step-down to generate a lower voltage or step-up to generate a higher voltage. There are also plenty of special options...

The new USB 3.0 – or “SuperSpeed USB” – protocol was developed to provide higher transfer rates, increased maximum bus power and device current draw, and new power management features, as well as new cables and connectors that are backward-compatible with USB 2.0 devices.
Integrating the maximum number of functions plus power management into the main chipset for portable, battery powered devices such as mobile phones with capability such as MP3, Mpeg4, and TV, would seem to be critical if an acceptable length of battery life is to be achieved.
The power MOSFET transistor, along with the decades of continuing device design optimization, has enabled new circuit topologies and improvements in power supply efficiency. The conversion from current-driven to voltage-driven power devices resulted in a rapid market adoption of these devices.
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.
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.
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...
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.
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.
