Carbon Nanotube Technology Promises a Revolution in Electrical Cabling

While carbon nanotube technology (CNT) has generated widespread interest for applications ranging from semiconductors to medical, one area that is a focus of research at TE Connectivity is high-performance electrical cables. TE has been actively researching CNT for wire and cable, including cooperative efforts with universities and industry leaders, and has prototype samples for evaluation. While there is still much progress to be made before CNT cables become main stream, we believe the technology is sufficiently advanced to meet specific niche applications such as satellites.

Intelligence Analysis System

Air Force intelligence analysts must assess an adversary’s capability to achieve their objectives, including their offensive and defensive systems, state of readiness, training, and conditions such as weather. To effectively assess these capabilities, analysts must integrate a tremendous amount of data from a number of sources. An automated decision support system can help analysts manage and process the information.

One-Shot Sniper System

The Defense Advanced Research Projects Agency (DARPA) has awarded Cubic Defense Applications, the defense systems business of Cubic Corporation, a $6 million contract to develop the next generation (XG) of the One Shot crosswind and range measurement system. The technology will provide ballistic aim point offsets in the shooter’s riflescope sight. The fielddeployable system is compact enough to have the option of mounting on the rifle or the spotter-scope, enabling military snipers to rapidly hit their targets at maximum effective ranges and under crosswind conditions.

Light Combat Tactical All-Terrain Vehicle

Oshkosh Defense, a division of Oshkosh Corporation, has unveiled its Light Combat Tactical All-Terrain Vehicle (L-ATV) utility variant for the Joint Light Tactical Vehicle (JLTV) program. The L-ATV utility variant fulfills the JLTV requirement for a two-seat cargo vehicle, while the L-ATV base variant meets the requirement for a 4-seat multipurpose vehicle. Both Oshkosh L-ATV variants leverage a common crew protection system, advanced automotive systems, and the patented Oshkosh TAK-4i™ intelligent independent suspension system to deliver a superior level of protection and off-road performance in a light vehicle.

Software Design for CFD Rotary-Wing Aeromechanics Modeling

Helicopter flight involves many multidisciplinary physics problems that are difficult to predict with today’s engineering modeling and simulation tools. Rotor aerodynamic systems involve complex interactions among the rotor blades, rotor wakes, and fuselage, and they create challenges such as simultaneous modeling of rotating and nonrotating components; retreating-blade, low-speed dynamic stall; advancing-blade transonic flow; rotor “trim” requirements to balance aerodynamic and dynamic forces for particular control settings; and strong coupling between rotor-blade aerodynamics and rotor blade dynamics (both rigid and elastic blade motion).

Crumple Zone Software Absorbs Attack Effects Before System Failures

A higher level of structural and operational endurance and ruggedness can be achieved in software systems by strategically introducing crumple zones (CZs) in the system architecture. Analogous to the crumple zone in an automobile, a CZ stands before critical components and “absorbs” the effects of attacks by localizing or eliminating the damage they can cause and leaving the critical components intact and unaffected. The concept of software CZs is broadly applicable; this work focuses on CZs for SOA.

General Runtime/Architecture for Many-core Parallel Systems (GRAMPS)

The era of obtaining increased performance via faster single cores and optimized single-thread programs is over. Instead, a major factor in new processors’ performance comes from parallelism: increasing numbers of cores per processor and threads per core. In both research and industry, runtime systems, domain-specific languages, and more generally, parallel programming models, have become the tools to realize this performance and contain this complexity.

Weapon Center of Mass Calculator

The Weapon Center of Mass (COM) software allows researchers to easily determine mass properties of a weapon system. The tool presents a photograph of the weapon and allows the user to place weight anywhere on the weapon by clicking on the screen. After the weight is placed, the software returns the mass properties of the weapon, including the effects of the added weight. It is based on fundamental equations found in physics and biomechanics, and can determine the effects of as many as four added weights. The added weight can be accoutrements (such as new sights), additional weapons (such as a grenade launcher), or any other object that is mounted to the weapon.

High-Speed Data Converter System Evaluation Kit

Texas Instruments Incorporated (TI) (Dallas, TX) has introduced the industry’s first complete high-speed data converter system evaluation kit (HSDC-SEK), which reduces system evaluation costs and enables designers to get their system running in minutes. The HSDC-SEK-10 includes a pattern capture card, pattern generator card, low-jitter clock source, clean 10-MHz signal source and a multi-output regulated power supply. The HSCD-SEK-10 can significantly reduce evaluation time and costs for a host of demanding applications in which high-speed data converters, such as the dual, 14-bit, 250-MSPS ADS4249 analog-to-digital converter (ADC) and the quad, 16-bit, 1.5- GSPS DAC34SH84 digital-to-analog converter (DAC), are key system performance drivers. Examples include test and measurement, communications, defense and medical equipment.
