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.

Healthy Sensing: Do You Know When Your Proximity Sensor Is Sick?

The age of the fully connected aircraft is upon us and it isn’t coming a minute too soon to meet the demands of today’s commercial aircraft. The integration of smart components helps to increase revenue and reduce the cost to serve. Honeywell has designed and implemented the patented FAVCO (Fixed Amplitude Variable Current Oscillator) technology, which allows for continuous health monitoring capable of detecting the majority of circuit and sensor faults.

Detecting Radioactive Material from a Remote Distance

In 2004 British national Dhiren Barot was arrested for conspiring to commit a public nuisance by the use of radioactive materials, among other charges. Authorities claimed that Barot had researched the production of “dirty bombs,” and planned to detonate them in New York City, Washington DC, and other cities.

Creating Simulated LIDAR Images of Human Poses in a Virtual Laboratory

Automated human activity recognition can provide clues about a subject’s intentions.LIDAR is a partial 3D standoff sensing method that illuminates a target with rotatory or flash laser beams, analyzes the reflected lights, and provides both the distance to the target’s surface and the target’s surface shape. An array of laser reflections can be used to map the facing-side surface of a target object as a partial point cloud. Unlike a 360° surface model generated by a traditional full body scanner, the partial point cloud from a LIDAR is a viewing angle dependent 3D representation of the target shape. The resolution of these maps depends on the density of the laser detector array; a good image of a human may require hundreds of detection pixels to capture enough detail to clearly detect changes in limb positions.

Advanced Sensors for Traumatic Brain Injury (TBI)

Implanted sensors could be used to measure intracranial pressure in TBI patients.The objective of this work was to use miniaturized, state-of-the-art pressure/temperature sensors engineered at Lawrence Livermore National Laboratory (LLNL) to measure the immediate increases in intracranial pressure (ICP) combined with longer-term measurements of biological ICP and intracranial temperature. The experience gathered from this work provided valuable data on sensor placement, long-term brain tissue responses to implanted sensors, and sensor capability of dual measurement of biologic ICP and impact pressure transients.
