Advances in Vision-Aided Navigation Keep Soldiers on Track

Eric Bickford, U.S. Army CERDEC engineer, compares the current prototype vision-aided navigation system with a 3-D rendition of a planned smaller, more soldier-wearable system. CERDEC engineers are analyzing the systems as a possible emerging and alternative navigation technologies for future combat operations. (Photo: U.S. Army RDECOM) The Army Materiel Command’s Communications-Electronics Research, Development and Engineering Center, or CERDEC, is using miniature cameras to create vision-aided navigation capabilities in GPS-denied situations.

Gas Sensor Monitors Pollution from Power Plants and Roads 

Experimental setup for the ultrasensitive real-time trace gas sensor. (Photo: Adelphi University) A research team from Adelphi University in New developed a new device that can detect ultra-low concentrations of gases like nitrogen dioxide accurately and nearly instantaneously. The device works even when experiencing small vibrations, which is important if the instrument is deployed in the field.

Wristband Sensor Predicts and Prevents Asthma Attacks

A prototype of the HET wristband. (Photo: NC State University) Researchers have developed an integrated, wearable system that monitors a user’s environment, heart rate, and other physical attributes with the goal of predicting and preventing asthma attacks. The system, called the Health and Environmental Tracker (HET), is composed of a suite of new sensor devices incorporated into a wristband and a patch that adheres to the chest.

Coding and Computers Could Help Detect Explosives

The top image shows a typical reading from a mass spectrometer, where each line indicates the presence of a certain substance. The bottom image shows a reading from the new coded aperture, where researchers rely on computers to collapse the numerous lines into a brighter version of the image above. (Photo: Jeff Glass, Duke University) A modern twist on an old technology could soon help detect rogue methane leaks, hidden explosives and much more. A Duke University team is using software to dramatically improve the performance of chemical-sniffing mass spectrometers.
