Airfield Lighting Heated Lens

Kopp Glass, Pittsburgh, PA

Incandescent lamps have been used as the primary light source in airfield lighting designs for many years. With recent environmental awareness of the general population and government regulation forcing greater energy efficiency, the lighting industry is rapidly transitioning to the use of light-emitting diodes (LEDs). LEDs offer greater energy efficiency by using a greater portion of the input electrical energy for light output, thereby reducing the heat output generated due to electrical losses.

LED Wingtip Navigation Lighting

Honeywell, Phoenix, AZ

Airbus, Toulouse, France

Honeywell's light-emitting diode (LED) wingtip navigation lighting is now standard on new production Airbus A320 Family aircraft, comprising the A318, A319, A320, and A321. Honeywell’s LED wingtip navigation lighting lasts up to 40 times longer than current halogen technology, greatly reducing operator maintenance costs. Drop-in LED replacements make maintenance quicker and easier.

Software Helps NASA Design One of the Greenest Federal Buildings

Autodesk® Revit® Architecture and Autodesk® Revit® Structure softwareGeneral Dynamics SATCOMAutodeskSan Rafael, CA415-507-5000www.autodesk.com

NASA Ames Research Center at Moffett Field, CA conducts critical research and development for the space agency, with a primary focus on supercomputing, networking, and intelligent systems. Recently, NASA Ames initiated work on the Sustainability Base, a $20.6-million facility designed to surpass standards for LEED Platinum™ sustainable design certification and approach net-zero energy consumption. When complete, it will be one of the federal system’s greenest buildings, and the first new NASA Ames facility in 20 years.

Motors Keep Telescope Operating in Record-Low Antarctic Temperatures

At Concordia Station in Antarctica, there is a telescope mount that has been operating for a few years. Recently, there was a new record temperature at the Dome C site: -84.6 °C, or -199 °F. Not many things operate well in such conditions, but the telescope mount — which has to move continuously — used for scientific studies by the Laboratoire Universitaire d’Astrophysique de Nice (LUAN) is one of them.

Robots and Vision Combine for Accurate Sheet Metal Cutting

In the general construction industry, many different parts are cut from sheet metal and then welded together on a large machine or vehicle. The trouble arises when the sheets are placed on the cutting table; the larger and heavier they are, the more difficult they are to position on the table. Without proper alignment, the sheet is likely to be cut outside acceptable tolerances, which results in waste and has a negative impact on the welding process. When sheets vary along the X, Y, and Z axes, the issue of exact positioning becomes even more problematic.

Visible Imager Technology for Euclid’s Dark Energy Mission

The European Space Agency is funding e2v’s development of an image sensor for the visible instrument in the Euclid space telescope. Euclid is a candidate mission for one of two launch opportunities in 2018. If selected, the mission aims to map the dark universe with two complementary methods: a galaxy red-shift survey and weak gravitational lensing using near infrared and visible instruments.

Vision System Finds and Aligns Electronic Components

Nordson Asymtek, headquartered in Carlsbad, CA, provides automated fluid dispensing systems, which are used in the assembly and packaging of semiconductors, printed circuit boards, flat panel displays, electronic components, and medical/biotech products. The dispensing system, however, requires machine vision alignment tools so that components can be easily located. For processes like underfill, which secures a flip chip to the substrate circuit board, and encapsulation, where a chip must be protected from corrosion, precision is essential.

General Dynamics to Supply Next-Generation Deep Space Network Antennas

Beam waveguide antennasGeneral Dynamics SATCOMTechnologiesNewton, NC828-464-4141www.gdsatcom.com

General Dynamics SATCOM Technologies has been chosen by NASA s Jet Propulsion Laboratory (JPL) to build two additional 34-meter (112-foot-wide) beam waveguide antennas as part of NASA’s modernization and transformation plan to continue scientific studies of the Earth as well as explore distant bodies in the solar system. The new antennas will be located at the Deep Space Network (DSN) facility in Canberra, Australia. The new antennas are part of a NASA plan to replace large, aging antennas that currently enable communications with NASA’s interplanetary flight missions.

Semiconductor Laser Technology Chosen for Space LIDAR

Single-frequency semiconductor laserRedfern Integrated Optics (RIO)Santa Clara, CA408-970-3500www.rio-inc.com

NASA has chosen Redfern Integrated Optics to further develop a single-frequency, narrow-linewidth semiconductor laser suitable for spaceflight operation. RIO’s external-cavity semiconductor laser technology is based on the hybrid integration of an indium phosphide (InP) gain chip and a planar lightwave circuit (PLC) with Bragg gratings. Packaged in a standard 14-pin compact “butterfly” package, the laser is characterized by a single-frequency output in the 1550-nm spectral region with a linewidth less than 2 kHz, low phase noise, low relative intensity noise (RIN), and high immunity to vibrations in a wide range of operating temperatures.

Crew Test Module Provides Launch Escape System

New Shepard rocket-propelled vehicle

Blue Origin Kent, WA 253-872-0411 www.blueorigin.com

Blue Origin has received funding from NASA’s Commercial Crew Development (CCDev) initiative to develop a composite crew test module and a launch escape system for its commercial spaceflight vehicle. The New Shepard system is a rocket-propelled, vertical-takeoff, vertical-landing vehicle designed to routinely fly multiple astronauts into suborbital space. In addition to providing the public with opportunities to experience spaceflight, the New Shepard system will also provide frequent opportunities for researchers to fly experiments into space and a microgravity environment.
