Flight Deck “Ouija Boards” Go Digital

To make the jobs of aircraft handlers easier, the Navy developed the Deployable Ship Integration Multi-touch System (DSIMS), a mobile software package that features a digital touchscreen image of a ship’s flight deck or hangar bay, and can be used on a laptop or desktop computer. It replaces the “Ouija board” replica of the flight deck.

Eye Tracking Technology Improves Imposter Detection Training

Customs and Border Protection (CBP) screens nearly one million people every day and secures and manages 328 ports of entry all over the country, including in remote areas. Verifying the identity of every single person entering the United States is a vital step in halting human trafficking, drug trafficking, and other smuggling attempts at the border. In addition, security screening prevents criminals and terrorists from entering the country. Imposter detection crosscuts the entire Homeland Security Enterprise, as well as state, local, and tribal law enforcement and even front-line soldiers in our military. All of these frontline operators execute this task as part of their respective missions and they must be able to accurately and efficiently verify identification of individuals to thwart imposters.

Robot’s Speed-of-Light Communication Could Protect You From Danger

Cornell University researchers are developing a system to enable teams of robots to share information as they move around, and if necessary, interpret what they see. This would allow the robots to conduct surveillance as a single entity with many eyes. Beyond surveillance, the new technology could enable teams of robots to relieve humans of dangerous jobs such as disposing of landmines, cleaning up after a nuclear meltdown or surveying the damage after a flood or hurricane. The project, called “Convolutional-Features Analysis and Control for Mobile Visual Scene Perception,” is supported by a four-year, $1.7 million grant from the U.S. Office of Naval Research.

Imaging Detonations of Explosives

Using high-speed camera pyrometers to measure and map fireball/shock expansion velocities.

An effort has been made within the US Army Research Laboratory (ARL) to extract quantitative information on explosive performance from high-speed imaging of explosions. Explosive fireball surface temperatures are measured using imaging pyrometry (2-color 2-camera imaging pyrometer; full-color single-camera imaging pyrometer). Framing cameras are synchronized with pulsed laser illumination to measure fireball/shock expansion velocities, enabling calculation of peak air-shock pressures. Multicamera filtering at different wavelengths enables visualization of light emission by some reactant species participating in energy release during an explosion. Measurement of incident and reflected shock velocities is used to calculate shock energy on a target.

Terahertz (THz) Radar: A Solution For Degraded Visibility Environments (DVE)

Operating at higher frequencies than other types of radar produces tighter beams and finer resolution.

An accurate view of the physical world is frequently vital. For example, rotary wing aircraft pilots must have knowledge of the terrain in order to safely fly their aircraft. Therefore, systems capable of generating images of the environment of sufficient quality to facilitate the decision process are necessary. The product of such a system is illustrated in Figure 1.

Creating the Future: A Better Way to Map Terrain

Mark Skoog, an aerospace engineer at NASA's Armstrong Flight Research Center, led the development of new software that stores terrain data in a more efficient and accurate way. The achievement, Skoog says, opens the prospect of anyone – yes, anyone – being able to fly.

How NASA Tracks the Asteroids Flying by Earth

On Wednesday, April 19, an asteroid missed Earth by 1.1 million miles – a distance closer than you might think. This week, Tech Briefs spoke with NASA’s Planetary Defense Officer about the efforts behind tracking this type of flyby.

Fragment Tracking Gives Insights Into What Happens In Explosions

A bang and a swirl of dust from detonating 9 pounds of plastic explosive in the desert signaled the beginning of tests that — thanks to advances in high-speed cameras, imaging techniques and computer modeling — will help Sandia National Laboratories researchers study fragmenting explosives in ways that weren’t possible before.
