As new laser devices become available, their complexity is met with increasingly sophisticated electronics that allow continuous refinement of precision. As optical systems mature, new processes and procedures are made possible. These include: lasers in medical diagnostic and treatment equipment (e.g. Optical Coherence Tomography (OCT)), increased sensitivity for environmental monitoring equipment
Designers of portable electronic devices have a variety of choices on types of chemistries, charger topologies and charge management solutions. Selecting the most suitable solution should be a simple task, but in most cases, it is a more complicated process. The designer needs to reach an optimal balance between performance, cost, form factor and other key requirements.
Supercapacitors are finding their way into an increasing number of applications for short-term energy storage. One such application is a power ride-through circuit, in which a backup energy source cuts in and powers the load when main power supply fails for a short time. This type of application has been dominated by batteries in the past
Recent advances in IGBT technology have given motor drive designers more options to consider for system development. Different specification conventions of various vendors complicate the design process further. Conventionally, system efficiency has been equated directly with VCEON. This metric is important for calculating the conduction losses of an IGBT but leaves out switching losses completely.
Robots that can make their own decisions have so far been confined to science fiction movies, but a child-sized figure with big eyes and a white face is trying hard to turn fiction into reality. Its name is iCub and scientists are hoping it will learn how to adapt its behavior to changing circumstances, offering new insights into the development of human consciousness.
Intended for automotive gate drive applications such as injection and solenoid driver management, the AUIRS2016S high-voltage power MOSFET high-side driver from International Rectifier provides negative voltage spike immunity against catastrophic events during high-current switching and short circuit conditions. The device’s output driver features a 250-mA high-pulse current buffer stage.
Rep. Rick Boucher, D-Va., chairman of the House Energy and Commerce Subcommittee on Communications, Technology and the Internet, is drafting a bill that would impose broad new rules on Web sites and advertisers. His goal: to ensure that consumers know what information is being collected about them on the Web and how it is being used, and to give them control over that information.
Google, the Internet search group, defended its scanning and publishing of millions of books online on Monday by saying the project was making finding information on the Web more democratic.
One of those facts of life that physicists live with is that every magnet ever made has a north and a south pole. When researchers try to split the two, they simply get another magnet with poles of its own.
In recent years significant advances in high-brightness LEDs (HB-LEDs) have given designers the opportunity to replace conventional incandescent, fluorescent and halogen technologies with more reliable and energy-efficient LED-based alternatives. As a result, solid-state lighting has seen considerable uptake in automotive, digital signage, and architectural applications, as well as the illumination of our city streets.
Ben Alexander spent nearly every waking minute playing the video game "World of Warcraft." As a result, he flunked out of the University of Iowa. Alexander, 19, needed help to break an addiction he calls as destructive as alcohol or drugs. He found it in this suburb of high-tech Seattle, where what claims to be the first residential treatment center for Internet addiction in the United States just opened its doors.
The executive who led Google Inc.'s expansion in China after being hired away from Microsoft Corp. following a high-profile court battle is leaving to start his own business, the U.S. search engine announced Friday. Kai-Fu Lee will step down as president of Google Greater China in mid-September, the company said. It said he would set up a new venture in Beijing but gave no other details.
This sleek sports-car by Rinspeed gives a new name to alternative fuels. Designed to run off of fermented green waste, the Advantige R One, a Formula One-style car, is no wimp and offers a few upgraded features so the driver still feels tough while driving his/her vegetable-eating vehicle.
In response to the Federal Communications Commission's request last month for comments about a definition of the term "broadband," key industry players have advised the FCC to tread carefully. The National Cable and Telecommunications Association, for example, is cautioning against incorporating substantive requirements regarding speed, price or openness.
Apple Inc's media extravaganza next week is being greeted with unusual calm, as it is uncertain if charismatic CEO Steve Jobs will appear and investors have nothing much to bet on apart from new iPods with cameras.
