Designed for use in synchronization and timing in WiMax applications, the Wi125 GPS timing receiver module from Connor-Winfield has an on-board programmable NCO oscillator that outputs a synthesized frequency up to 30 MHz. Steered by a GPS receiver, the self-survey mode of operation allows the receiver to enter a position hold mode
NASA strategy proposal shifts the U.S. human space program away from returning to the moon in favor of a stepping-stone approach aimed at reaching Mars, including using commercial space launch services, according to a document seen by Reuters.
Microsoft Corp., Yahoo Inc. and a prominent antitrust lawyer urged a federal judge Tuesday to block a class-action settlement that would give Google Inc. the digital rights to a vast library of books. As that coalition warned of a literary cartel that would lead to higher prices and less competition, Sony Electronics, a technology trade group and economics professors came to Google's defense
Palm Inc., which revitalized its product line with the Pre smart phone launch in June, is hoping to keep momentum going with the release of a lighter, cheaper handset called the Pixi. The company said Wednesday that the Pixi will be available during the holiday season through Sprint Nextel Corp., currently the Pre's exclusive wireless carrier.
Although there are some significant variations and investment in new networks, fixed broadband penetration in Central Asia and the Caucasus remains low. One factor holding back development has been political.
Provided in voltages from 50 V to 5000 V in currents from 30 A to 30,000 A, single, three- & poly-phase AC to DC converters from APS are available in air- and liquid-cooled versions. Standard versions as well as custom models designed to end-user specs address applications that include UPS, wind power, induction heating, and welding.
Absopulse Electronics’ HVI 2K high input voltage DC/DC converters can generate 2 kW output power and accept a 600 VDC input voltage (450 V to 800 VEC range). This single output unit delivers 12 V/130 A, 24/80 A or 48 V/40 A. An optional built-in redundancy diode allows
Available in 3300k, 4200k, and 6500k white in lengths from 1 to 5 feet, Marktech's line of T9 LED Light Tubes have a color rendering index (CRI) of 80. Provided in versions with a 50 degree or 120 degree emission angle
Backlight technology continues to markedly improve, day after day, making it possible to design LCD panels as thin as a picture frame. Many thought that the use of OLED technology would be the only way to provide ultra-slim TV sets, but this year Samsung’s introduction of a new type of LED (light emitting diode) technology completely changed that thinking. Now, there are LED LCD TVs with depths as thin as 1.2 inches.
Texas Instruments introduced a four-channel, high-voltage, bipolar digital-to-analog converter (DAC) for ATE and medical equipment design. The DAC8734 features drift characteristics of 2 ppm over 500 hours; 3 ppm over 1000 hours, and it comes in a 6 mm x 6 mm QFN-40 or 7 mm x 7 mm TQFP-48 package. The device is capable of
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.
