Two astronauts cut short their spacewalk and hurried back to the safety of the international space station on Wednesday after a suit problem resulted in rising carbon dioxide levels for one of the men. NASA officials stressed that spacewalker Christopher Cassidy was never in any danger and experienced no symptoms of carbon dioxide buildup. The trouble cropped up late in Wednesday's spacewalk, the third for shuttle Endeavour's crew.

Operating from a single 0.9 V to 3.6 V supply, the AS1344 high voltage DC-DC boost converter from austriamicrosystems provides adjustable output voltages in the range of 5.5 V to 42 V. The boost converter features a 1 MHz fixed switching frequency and supply current of 22 µA. The AS1344 offers 2% output voltage
Designed for commercial and light-industrial OEM applications, the Pittman ‘I Series’ brushless DC servo motors from Ametek offer performance capability from 40 W to 1700 W continuous. The winding system allows for operation on machine bus voltages from 12 VDC to 325 VDC.
Simplifying device set-up and installation time, TURCK’s interface module family takes programming input via a PC or on-board push buttons using FDT/DTM software, along with PACTware. The devices can monitor motor speed, shaft speed and conveyors, as well as the temperature of RTDs and thermocouples.
Addressing military, aerospace and automotive function test, has dual-threshold voltage inputs from 0.3 V to 50.0 V with nominally 12.5-mV resolution. The 40-413-001 has 32 high-side 2-A output drivers, the 40-413-002 has 32 low-side 2-A drivers, and the 40-413-003 includes both high- and low-side drivers.
Federal agencies are facing a severe shortage of computer specialists, even as a growing wave of coordinated cyberattacks against the government poses potential national security risks, a private study found. The study describes a fragmented federal cyber force, where no one is in charge of overall planning and government agencies are "on their own and sometimes working at cross purposes or in competition with one another."
Hawaii was chosen Tuesday as the site for the world's biggest telescope, a device so powerful that it will allow scientists to see some 13 billion light years away and get a glimpse into the early years of the universe. The telescope's mirror — stretching almost 100 feet in diameter, or nearly the length of a Boeing 737's wingspan — will be so large that it should be able to gather light that will have spent 13 billion years traveling to earth.
Philips Lumec has been chosen by the Eastern Band of Cherokee Indians of western North Carolina to light their downtown streetscapes with their environmentally responsible LED lighting solutions. In doing so, they clearly place this town of 14,500 residents, located on the South end of the Great Smoky Mountains National Park, in the vanguard of communities choosing environmentally responsible LED lighting technologies.
Leadis Technology, Inc. (NASDAQ: LDIS), an analog and mixed-signal semiconductor developer of LED drivers for consumer electronic devices, today announced sample availability of the LDS9001 and LDS9003, two new LED controllers featuring Leadis' patent pending LED-Sense(TM) Temperature Compensation engine. This innovative feature allows for direct in-situ monitoring of the LED junction temperature without the need for an external temperature sensor
Even in space, batteries need to be replaced. The primary task of a spacewalk Wednesday will be to replace four batteries on one of the international space station's solar arrays. Astronauts David Wolf and Christopher Cassidy's spacewalk is scheduled be the third of Endeavour's 16-day mission to the orbiting outpost.
When Neil Armstrong stepped onto the surface of the moon, it was a first for the Soviet Union - the first time the U.S. had beaten the U.S.S.R in the space race. Forty years later, the memory of that loss of primacy still seems to sting the Russian soul. When state TV channel Rossiya reported last week on the restoration of video footage of the Apollo 11 moon landing, the account gave a lot of attention to dubious conspiracy theories that the landing was faked.
The Electronic Design Automation Consortium (EDAC) is sponsoring the Free Monday exhibit program on Monday, July 27 at the 46th Design Automation Conference (DAC). In addition to the exhibition, Exhibitor Forum, IC Design Central Pavilion, and the Keynote Panel, Free Monday registration includes access to the DAC Pavilion (Booth #1928) where six Pavilion programs will be presented that day.
The Design Automation Conference (DAC) announced today that it will feature 29 companies exhibiting at this year’s conference for the first time. The new exhibitors include companies ranging from providers of design tools and data management solutions to product development experts and placement firms. The 46th DAC will be held July 26 – 31 at the Moscone Center in San Francisco and DAC exhibit hours will be 9 a.m. to 6 p.m. Monday, July 27 through Wednesday, July 29 and 9 a.m. to 1 p.m. on Thursday, July 30.
