From a modest start in 1990, lithium-ion cell production has mushroomed into a multibillion-units-per-year industry with manufacturing facilities spread all over the world. Because of the potential for dangerous thermal-related incidents during the manufacture and use of Li-ion cells, extreme care must be taken during the manufacturing processes to produce high-quality cells that are as safe as possible.
In the era of global wireless connectivity, almost nothing is more important than keeping a smart phone or mobile Internet device charged. Expanding features on the constantly improving portable and handheld device create a major challenge for designers of battery charger ICs.
Selecting an optimal multicore chip or SoC architecture is considerably more complex than picking a lone processor chip or core. As with processor selection, benchmarks can help. A good multicore benchmark will identify bottlenecks in the multicore system design including memory and I/O bottlenecks, computational bottlenecks, and real-time bottlenecks.
Geeks, the most misunderstood of all species (yes, I’m a member), are notoriously difficult to shop for. We don’t bow to the fashion gods (to put it kindly), our literary tastes are unpredictable, and as for electronics, forgetaboutit—only geeks know what other geeks want. Thus, I present Gifts for Geeks. If you’re a parent/friend/relative with one of these eclectic individuals on your shopping list, take note.
Electronics packaging solutions are developed on many levels, from the board architecture all the way up to the mechanical enclosure. The individual elements that compose these solutions need to work together so that the device can pass compliance tests.
For humans, an unobserved fall can have very serious consequences. In some cases, the initial injury can become more traumatic if not treated within a short time. In other cases, an individual can suffer an accidental fall as the result of weakness or dizziness due to a diminished self-care and self-protective ability.
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...
What is your opinion on the incandescent ban?
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.
