iSLC Flash Technology

Robots have been employed by the military to assist in missions where it would be, and has been, too dangerous to have a human being take on the task. These robots can detect and disable bombs. Some can be thrown into rooms where they land on their “feet”, and scan the room for counter-insurgents. Others blow up mine fields, to ensure safe travel of ground vehicles and the personnel they carry.

OpenVPX(R) 40G Ethernet + InfiniBand(R) Switch Card

Curtiss-Wright Controls Defense Solutions (Ashburn, VA), a business group of Curtiss-Wright Controls, has introduced the newest member of its Fabric40(TM) family of extremely high-speed 40 Gbps OpenVPX™modules. The new VPX6-6802 Fabric40 Switch is the first rugged, high performance 6U OpenVPX (VITA 65) switch card to provide support for 10/20/40 Gigabit Ethernet (GbE) and SDR/DDR/QDR/FDR-10 InfiniBand®(IB) connectivity to OpenVPX™ systems. Systems built using the VPX6-6802 and complementary Curtiss-Wright Fabric40 system elements will deliver over 2x the performance of previous generation SRIO Gen-2-based systems and 4x the performance of 10 GbE-based systems. The fully rugged VPX6-6802 is available in air-, conduction-, and air flow-through (AFT)-cooled configurations. Designed for use with today’s highest speed switched fabrics, the board provides a combined Data Plane and Control Plane high-performance switch for 6U VPX systems.

Power MOSFETs

Mouser Electronics, Inc. (Mansfield, TX) now stocks International Rectifier’s (IR) family of AEC-Q101 Automotive qualified 40V N-channel MOSFETs, featuring IR’s proven Gen12.7 trench technology with ultra-low Rds(on). International Rectifier's Automotive COOLiRFET™ Power MOSFETs target rugged automotive applications. These HEXFET® Power MOSFETs achieve very low on-resistance, resulting in highly efficient switching of high current signals with very little power loss. Additional features include a high 175°C junction temperature, fast switching speeds for better power efficiency, and a high repetitive avalanche rating for harsh signal environments. These new devices offer low conduction losses and robust avalanche performance to deliver higher efficiency, power density and reliability. Applications using these new IR COOLiRFET™ devices from Mouser Electronics can run significantly cooler than comparable MOSFETs.

Projected Capacitive (PCAP) Touch Panel

(Dallas, TX) has announced the addition of an 18.5-inch projected capacitive (PCAP) touch panel to the Crystal Touch: TRUE Multi-Touch PLUS standard product line. Crystal Touch: TRUE Multi-Touch PLUS panels provide a true multi-touch interface with a pre-integrated, optically bonded, soda-lime cover glass with a decorative black border. The additional layer of glass adds durability and is ready to be incorporated into touch driven devices. The 18.5-inch PCAP touch panel allows for up to 16 simultaneous touches and features the Atmel® maXTouch™ mXT1664S controller. The combination of Ocular's Crystal Touch technology and Atmel's maXTouch line of touchscreen controllers provide a robust and sophisticated touch solution that can identify and disregard unintended touches.

Closed-Loop I2S Audio Amplifiers

Texas Instruments (TI) (Dallas, TX) has introduced a family of four digital-input, closed-loop I2S amplifiers for mid-power stereo audio applications including TVs, soundbars, portable docking stations, Bluetooth® speakers, and aftermarket automotive audio products. The TAS5760xx devices feature high switching frequency, allowing designers to use smaller output filter components to reduce overall solution size and bill of materials (BOM) cost. They stream 20W continuous power per channel without a heatsink, and deliver superior performance specifications, including THD+N of 0.03 percent at 1 W, crosstalk of -92 dB, and 66-uV idle channel noise.

Confocal Imaging System for Ultra-Fast, Three-Dimensional Transport Studies in Thermal Management Applications

The objective of this work was to develop a high-speed, three-dimensional (3D) confocal imaging system to study coupled fluidic and heat transport processes for high-performance thermal management applications. However, to successfully implement these approaches, fundamental understanding of interfacial dynamics and transport processes was necessary.

Evaluating a Data Clustering Approach for Lifecycle Facility Control

Given the current emphasis on sustainability, there is a growing interest in monitoring various facets of building resource consumption. Building monitoring and automation systems most commonly exist as closed-loop systems for security, fire safety, water, electrical, and HVAC (Heating, Ventilation, and Air-Conditioning). One of the fundamental requirements of a mature engineering process model is the comparison of planned versus actual results for cost, risk, and quality control. For facility engineering, this implies that there must be a structured specification of building space requirements and a mechanism for detecting divergent system and occupant behaviors. Such a mechanism would have broad applicability for commissioning, energy efficiency, sustainability, diagnostics, maintenance, and a variety of other problems.

Portable Data Recorder for Measuring Sand Grain Fracture After Blasts

Abullet cannot penetrate through a sandbag while an arrow can, so understanding the behavior of granular materials such as sand and its energy absorption in a blast is critical in the design of armor. To this end, as part of the “Soil Blast Modeling and Simulations” project sponsored by the Office of Naval Research’s Multidisciplinary University Research Initiative (MURI), experiments were performed using a portable data recorder to determine the mechanical behavior of sand grains under confined compression.
