NASA on Wednesday unveiled the first deep space photos taken by Hubble since its billion dollar repair mission last spring. That work included installing two new cameras, other science instruments and replacing broken parts.
The mad scramble to obtain incandescent bulbs ahead of the EU ban highlights a controversial practice—the forced obsolescence of old technologies. R&D, combined with market forces, often collude to bury legacy tech. But should government speed up this process? How important is consumer choice?
A White House panel of independent space experts says NASA's return-to-the-moon plan just won't fly.
President Barack Obama warned American teenagers on Tuesday of the dangers of putting too much personal information on Internet social networking sites, saying it could come back to haunt them in later life. The presidential words of advice follow recent studies that suggest
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
