Eye Tracking Technology Improves Imposter Detection Training

A screen shot of the Eye-dentify user interface.

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.

Determining Detection and Classification Potential of Munitions Using Advanced EMI Sensors in the Underwater Environment

Electromagnetic induction could be used to locate and characterize potentially dangerous sunken metallic objects.

Hazardous ordnance items are present along coastlines and in rivers and lakes in waters shallow enough to cause concerns for human recreational and industrial activities. The presence of water makes it difficult to detect and remove these hazardous legacies induced from wars, military training and deliberate disposal. Various techniques have been proposed to detect and characterize Unexploded Ordnances (UXO) and discarded military munitions (DMM) in the underwater environment including acoustic waves, magnetometery, and electromagnetic induction (EMI).

Lightweight Artificial Hair Sensors Could Enable “Fly by Feel”

The Artificial Hair Sensor was inspired by the hairs on bats and crickets.

The Air Force Research Laboratory was inspired by the hairs on bats and crickets in creation of artificial hair sensors that could assess the external environment and change maneuvers during flight. The need to understand ambient air data and its effects on aircraft performance, navigation, and more has become more critical as aircraft are now lighter and operate in diverse environments.

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.

Iowa State University tested slabs of electrically conductive concrete at Des Moines International Airport. The test slabs are made up of 1 percent carbon fiber and a special mix of cement, sand, and rocks. The carbon fiber allows the concrete to conduct electricity, but there is some resistance to the moving electrons, which creates heat.

Luminescence Materials as Nanoparticle Thermal Sensors

Particles could be used to record critical temperature history data during agent-defeat weapons testing.

The purpose of this research program was to create and study novel luminescence particles (phosphors} capable of sensing and retaining the time-temperature information to which they were exposed, therefore acting as nano- and microsized thermosensors. The thermometric property is the latent thermoluminescence (TL) signal associated with electron/hole pairs trapped at defect energy levels, which are differently affected by the environmental temperature.

Using Dempster-Shafer Fusion for Personnel Intrusion Detection

New technique enables the use of ultrasonic micro-doppler and PIR sensors for improved security.

The Dempster-Shafer (D-S) mass function is used in effect as a common representation of heterogeneous sensor data. In order to cast each data source in this form, first the raw data is reduced to points in a multi-dimensional feature space specific to each sensor. From there, an approach is outlined that uses a distance metric in the feature space to assign mass to each state in the class hierarchy. This hierarchy begins with the full frame of discernment which represents complete uncertainty. From there it proceeds as an n-array tree broken down into further subclasses until the finest granularity of classification for the specific sensor is reached.
