Four-Channel Intelligent LED Controllers

Saelig Company Inc. (Fairport, NY) has announced the LED-Warrior04, a 4 channel, intelligent, programmable LED constant-current driver with DALI, DMX512, and I2C interfaces on board. Other bus protocols or wireless options can be added via the I2C interface. For each of the four channels, the forward current and brightness of the LEDs can be individually and independently programmed. Current can be programmed from 80 mA to 1000 mA in 5mA steps. Brightness is controlled by internal 12-bit PWMs for each channel, allowing 4096 steps, with dimming down to 1/4096 or 0.024%. The high resolution of brightness control allows precise color mixing or calibration of multiple LED groups. The four 12-bit channels allow up to 281 trillion color hues. www.saelig.com

Products of Tomorrow: February 2015

The technologies NASA develops don’t just blast off into space. They also improve our lives here on Earth. Life-saving search-and-rescue tools, implantable medical devices, advances in commercial aircraft safety, increased accuracy in weather forecasting, and the miniature cameras in our cellphones are just some of the examples of NASA-developed technology used in products today.

NACA Technology: Then and Now

“Be patient, if you want to see the concrete benefits of space research. I am confident that the benefits are there. We at NASA have been given a big job— planning and executing the nation’s civilian space program. But I would first like to dispose of a question that is asked of me quite often: Why venture at all into the unknown, towards the Moon, the planets, and then towards the stars so far beyond? One answer was given by Tsiolkowsky, the 19th century scientist who Russia considers the grandfather of space. It was that the Earth is the cradle of the mind, but one cannot live forever in a cradle.”

Tech Briefs Interview: NASA’s Kathy Lueders

At the annual meeting of the Society of Automotive Engineers (SAE) in Detroit on January 14, 1959, NASA’s first Administrator, Dr. T. Keith Glennan, said: “I can imagine a remote future when spaceflight, in some form, might become nearly as commonplace as air travel is today.”

Video Wall Monitors Space Station Science

Clarity™ Matrix LCD Video Wall System Planar Systems Beaverton, OR 866-475-2627 www.planar.com A Clarity Matrix video wall system was installed at NASA’s Payload Operations Integration Center (POIC) at Marshall Space Flight Center in Alabama to monitor and manage science being conducted on the International Space Station (ISS). The POIC has been operational since 2001 and, during that time, flight control and other center personnel have monitored and managed ISS mission progress using a mix of large-scale computer monitors and a complement of large-scale projection screens to view ISS activities and share information. In the newly renovated POIC, a video wall of 24 displays has been installed in front of and above the flight control positions. Operational since mid-2013, the video wall provides capabilities that enhance collaboration among the ground team and enable them to more efficiently help the ISS crew and researchers around the world to perform science on station.
