Optical System Enables Imaging of Ultrafast Phenomena

A new, all-optical method for compressing narrow electron pulses to a billionth of a billionth of a second could improve real-time movies of chemical reactions and other ultrafast processes.

Camera Reveals Details Invisible to the Naked Eye

Researchers at the University of Washington and Microsoft Research developed HyperCam, a lower-cost hyperspectral camera that uses both visible and invisible near-infrared light to “see” beneath surfaces and capture unseen details. Hyperspectral imaging is used today in everything from satellite imaging and energy monitoring to infrastructure and food safety inspections, but the technology’s high cost has limited its use to industrial or commercial purposes.

Infrared Camera Detects Industrial Gas Leaks

A new low-cost infrared camera makes it possible to quickly and efficiently detect gas leaks that can occur in different industrial facilities. The system can detect gas leaks that are normally invisible to the human eye thanks to a camera that recognizes the infrared signature of these compounds (infrared is electromagnetic and thermal radiation with longer wavelengths than visible light).

Method to Reduce Stabilization Time for Shape Memory Alloys (SMAs)

Shape memory alloys (SMAs) are metals that “remember” their original shape. After being deformed, SMAs return to their original shape with the application of heat.

EADIN Lite Communication Network

DEC is part of the Transformational Tools and Technologies (TTT) project under the Advanced Aeronautics research program. John H. Glenn Research Center, Cleveland, Ohio The distributed engine controls (DEC) task seeks to investigate the capabilities of a distributed network for aircraft engine controls. Traditional aircraft engine control systems use analog systems to communicate with sensors and actuators. The ability to upgrade an engine after manufacture, by swapping out sensors or actuators, is limited due to the analog signal component. Digital signals do not have this limitation, and additionally they do not require dedicated cabling, which may decrease engine weight. To understand the interactions between a new digital network and the engine controller, a representative model of the networks is required.

Iris DSN-Compatible, CubeSat-Compatible Transponder

RF portions are combined with FPGA processing inherited from prior systems, which opens up a series of new possibilities. NASA’s Jet Propulsion Laboratory, Pasadena, California No CubeSat-compatible, Deep Space Network (DSN)-compatible communications and navigation transponder exists at the time of this reporting. In order for CubeSats and other small spacecraft to go into deep space, a DSN-compatible capability is needed.

Cockpit Avionics Upgrade Display Atlas, Generic Display Software, and Electronic Procedure System

This computer training system uses nine screens to mimic avionics controls. Lyndon B. Johnson Space Center, Houston, Texas Modern avionics permit user interfaces on spacecraft to be performed on computer screens instead of with physical controls. This saves a great deal of weight; however, it presents challenges with representing all the various controls and gauges as well as flight procedures and data on the limited screen real estate available in a practical cockpit.
