Customized Drone Maps Glacier Growth

Using a custom-designed drone, a researcher from The Ohio State University mapped glaciers and wetlands in Peru’s Cordillera Blanca mountain range. Despite a discovered drop in glacier growth, the findings from the unmanned aerial vehicle (UAV) revealed a slightly more optimistic picture of the region’s water supply, which relies in part on the ice formations.

Cambridge Researchers Take Computer Vision for Test Drive

Google's driverless car, like many autonomous vehicles in development, is packed with sensors, radars, lasers, and cameras. To lighten the load of sensing devices in self-driving autos, researchers at Cambridge University have hit the streets with a system that uses only computer vision.

Using Optical Imaging to Combat Counterfeit Components

Counterfeit parts and materials pose a serious threat to the United States defense supply chain. The National Defense Authorization Act (NDAA) of 2012 (Section 818) laid out strict guidelines for DoD prime contractors for detection and avoidance of counterfeit electronic parts1. The Defense Logistics Agency (DLA) identified six federal supply groups in their supply chains that are at high risk for counterfeiting including electrical and electronic components, bearings, hardware and abrasives, pipes and fittings, engine accessories, and vehicle components2. DLA is championing development of anti-counterfeiting technologies that also provide traceability for the parts in its supply chain. A solution called QuanTEK developed by Chromo Logic LLC, involves novel optical imaging methods and has been found to work on a broad class of the DLA identified high-risk federal supply groups.

Manufacturing OLED Lighting

Organic Light Emitting Diode (“OLED”) lighting panels are thin planar area light sources that are naturally diffuse, low glare, high color rendering, cool to the touch, highly energy efficient and highly controllable. Together with LED light sources, they compose the solid state lighting technologies that are replacing over 100 years of bulb and tube lighting technologies, just as solid state electronics have replaced the bulbs and tubes used in electronic devices such as radios, computers and displays.

Advanced Holography Offers 3D Fire Measurements

In a propellant fire, large molten aluminum drops form at the burning surface. The drops are lofted into the environment and can severely damage anything that they fall on. Liquid breakup must be understood to predict the scale and intensity of such fires.

Cameras Provide Critical Data for NASA Rocket’s First Flight

On March 11, NASA tested the powerful five-segment booster for NASA’s new rocket, the Space Launch System. To provide critical data for the rocket’s first flight, eight cameras with more than 40 different settings — including varying exposures — were set up near the forward portion of the booster. During the two-minute test, the cameras were computer-controlled and cycled through pre-programmed settings.

3D Vision System Aids 560-Mile Piloted Drive

Audi completed a long-distance test drive of its Audi A7 Sportback semi-autonomous concept vehicle, finishing the journey at the International CES 2015 consumer electronics show in Las Vegas. The “piloted driving” — Audi’s take on combining autonomous driving with individual control — began in Stanford, California and ended two days and 560 miles later on January 6, 2015.

3D Volumetric Display Technology

The United States government spends a lot of money on its defense programs, investing in the training and technology necessary to arm and prepare the most advanced fighting force on the planet. The price tag for these efforts reached $581 billion in 20141 as various branches of defense continued to dedicate funds toward the research and development of innovative tools and technology.
