3U OpenVPX Backplanes

Pixus Technologies (Waterloo, Ontario, Canada) has announced new 3U OpenVPX backplanes in 5-slot and 6-slot sizes. The 5-slot OpenVPX backplane features a mesh topology, and the 6-slot version has a distributed topology. Both backplanes are designed for speeds from 3.125 Gbaud/s to 6.25 Gbaud/s, and they come with or without RTM connectors.

Eyes In The Sky

Unmanned aerial vehicles (UAVs) are critical to today’s intelligence, surveillance, and reconnaissance (ISR) missions, supplying valuable aerial imagery to ground forces. Small UAV systems are a highly flexible ISR solution since they can be quickly deployed with minimal infrastructure and manpower. Unfor tunately, their performance is hindered by limited bandwidth communication links and the stringent size, weight, and power (SWAP) constraints of small UAVs, which make onboard real-time processing of imagery impossible. As a result, a potential game-changing combination of high-resolution cameras and small UAVs has not yet been realized.

MISRA C:2012

For C programmers working on safety- critical applications, following restrictions and guidelines to ensure safe-coding practices can be painful. Features of the language designed to make your work easier, more efficient, or provide work-arounds for obstacles are often just the features that the guidelines disallow. However, whether for avionics or in the midst of battle, a problem with the software is the last thing needed. The risks prohibit taking chances.

System Could Detect Concealed Person-Borne Bombs at a Distance

The recent tragic events at the Boston Marathon illustrate the growing and critical need for the detection of person-borne improvised explosive devices (PBIEDS). Such systems, in fact, are currently under development under the guidance and supervision of the Department of Homeland Security. These sophisticated next-generation radar systems are being designed to detect bombers at long distances, in crowded areas, and even at non-fixed locations.

CompactPCI Steps Into the Future

CompactPCI Serial has proven to be a beneficial technology upgrade for a number of embedded systems designers accustomed to working with the legacy CompactPCI platform. Not only does CompactPCI Serial bring modern serial interfaces and a ruggedized connector scheme into play, but it also provides significant cost advantages while adhering to many known design principles, lessening a developer’s need to learn a new and complex technology.

The Evolution of AdvancedTCA: From telecommunications to military, aerospace and security

The Advanced Telecom Computing Architecture (AdvancedTCA® or ATCA®) is a series of open standard computing platform specifications originally ratified in 2002 to meet the needs of carrier grade communications equipment, primarily for core network telecommunications applications. In the 11 years since ATCA products first appeared on the market, there have been numerous advances in the governing standard, the products available, and the products and applications that are driving its adoption and growth.

Armor Kits for Heavy Trucks

Over the last several years, the Army has initiated and implemented a Long Term Armor Strategy (LTAS). The LTAS provides modular armor protection for vehicles that vary dependent upon threat levels. The B-Kit consists of both transparent armor and opaque armor and provides a higher level of protection for the troops. They can be readily stored, applied, or removed by troops in the field per mission requirements.

High-Resolution, Measurement-Based, Phase-Resolved Prediction of Ocean Wavefields

Given remote and direct physical measurements of a realistic ocean wavefield, the goal of this work was to obtain a high-resolution description of the wavefield by integrating the measurements with phase-resolved wave prediction models including realistic environmental effects such as wind forcing and wave breaking dissipation. The measurements necessary for achieving this reconstruction were guided, and the validity, accuracy, and limitations of such wavefield reconstructions were addressed.

Measuring Impact Damage to Toughened CFRP Laminates with Time Domain Reflectometry

Laminated Carbon Fiber Reinforced Polymer (CFRP) composites are very effective in weight saving in aeronautical structural components. For these laminated CFRP structures, it is difficult to detect damage such as delamination, matrix cracks, and local fiber breakages caused by low-velocity impact loading because these damages are difficult to detect from the outside of the structure. This difficulty of inspection of the laminated CFRP structures demands the development of automatic monitoring or damage detection systems.
