Patent offices in the United States and the United Kingdom have announced a trial program geared to streamline the process of obtaining a patent in the countries.
The capacitive-sensing user interface is beginning to emerge as a practical and innovative upgrade for mechanical buttons in mobile handsets. When a handset is enabled with touch sensors, handset makers obtain exciting new look-and-feel options for their designs.
Engineers are increasingly designing touchscreens into portable devices. This article discusses the construction of a resistive touchscreen panel and the inner workings of a typical four-wire resistive screen. It also discusses some hardware low-power strategies.
As data rates increase, signal integrity becomes the most critical factor for design engineers. Instead of implementing SI enhancement techniques, design engineers can simply add jitter eliminators such as equalizers to their designs.
As designers of high-performance systems strive to achieve higher bandwidth while meeting critical timing margins, a performance bottleneck standing in their way is the memory interface.
The CD is on the way out for this consumer application. According to music-industry market-research sources, sales of the CD as a music medium have dropped about 20 percent since last year.
As the market for short-range devices expands, the idea of a one-size-fits-all transceiver is simply out of the question, thus designers of these systems must consider the device tradeoffs and their impact on link robustness and battery life.
Embedded systems designers are facing both gradual and abrupt changes in their debugging tools: tools are moving toward standardized, open systems and tool developers are adding wireless connections to embedded debug.
Cisco Systems Inc. cofounder Len Bosack has unveiled the optical-transport fruits of his company, the device dubbed the DXM the transport system.
Technologies of computer interfaces and graphics expected in the next 10 years took the spotlight at this year's Siggraph exhibition, including a virtual video recording system and multitouch displays among others.
Manufacturers and researchers have provided a peek inside their advanced multicore processors and research into the on- and off-chip networks that those future microprocessors may use at the Hot Chips and Hot Interconnects conferences.
Vishay Intertechnology Inc. released seven p-channel power MOSFETs in a PowerPAK ChipFET package that is said to offer advanced thermal performance in a compact, 3mm x 1.8mm footprint.
Touchscreens are on the upswing, with global shipment revenue for the leading displays rising to $4.4 billion by 2012, up from $2.4 billion in 2006.
