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.

Heated Concrete Could Pave the Way for Ice-Free Runways

Heated test slabs installed at Des Moines International Airport. (Photo: Halil Ceylan) 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.

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.

Open Standard Middleware Enables New HPEC Solutions

The military embedded computing landscape has been transformed from where it was 20 years ago — and that has been almost entirely enabled by the ability of prime contractors, systems integrators, and OEMs to leverage the products of COTS manufacturers who take leading edge commercial technologies and apply them successfully to the world of military computing. A look at the commercial landscape today reveals cell phones that are putting vast amounts of location- aware information — and the ability to process that information — directly into the hands of consumers. The Internet of Things has become a deployable reality, with data derived from millions of connected sensors.

Laser-Based Navigation Sensor Could be Standard for Planetary Landing Missions

NDL is about the size of a breadbox and contains three lasers, each about the size of a piece of corn on the cob. (NASA/David C. Bowman) A laser-guided navigation sensor that could help future rovers make safe, precise landings on Mars or destinations beyond was developed at NASA’s Langley Research Center. The Navigation Doppler Lidar (NDL) will act as a GPS for Mars spacecraft.

The Economics of Accuracy in Low-cost, High-volume Sensing Applications

Various research firms forecast the market for portable medical devices to be somewhere around the $20 billion-range within the next several years. Part of the increased demand is due to an aging population with more chronic conditions. These smaller portable units requires devices with smaller footprints. By the same token, smaller devices need to provide adequate levels of care to ensure patient safety and comfort. Thus, functionality cannot be sacrificed for space.
