Rugged Sunlight Readable Tablet

AMREL (Los Angeles, CA) announced the launch of APEX PX5, a 10.1" fully rugged, sunlight readable tablet. The APEX PX5 is built to meet modern demands with a tough magnesium chassis and a durable ABS plastic cover. Boasting a speedy 4th generation Intel® Haswell Core™ i5 processor, the APEX PX5 Tablet is ideal for graphic and other data-intensive applications. Its capacitive multi-touch display is made from scratch-resistant Corning Gorilla Glass 3 and supports glove touch, and a digitizer option.

DC/DC Converters

Gaia Converter (Laval, QC, Canada) has extended its ultra-wide input voltage range DC/DC Converters platform to the new High Rel MGDD-08 series, targeting military and airborne applications. The MGDD-08 Series 9-60V & 80V transient input voltage range complies with Mil-Std-1275, 704 or DO-160 standards without an additional front end protection device. This unique performance is achieved via Gaia’s proprietary switching techniques while also keeping efficiency over 90%. With 2 outputs (for parallel, serial or symmetrical operation) of 3.3V, 5V, 12V, 15V and 24V, they can cover a wide variety of needs such as single 3.3V to 48V output, +&- 15V or 2×24V outputs for example.

VPX™ ExpressFabric® Switch

Concurrent Technologies (Woburn, MA) recently announced FR 341/x06, a new 3U VPX™ ExpressFabric® switch. FR 341/x06 supports six payload boards and is based around an Avago Technologies PEX9700 series device which is fully Gen 3 PCI Express® compatible with additional ExpressFabric capability. Similar to Concurrent Technologies’ existing FR 331/x06 3U VPX switch, it provides PCI Express data and Ethernet control plane links but with higher performance and more flexible configurations.

Waveguide Mixer

Anritsu Company (Richardson, TX) has introduced the MA2806A High Performance Waveguide Mixer that can be integrated with its MS2830A Spectrum/Signal Analyzer to create a millimeter-wave (mmWave) measurement solution. When used with the MS2830A-044/045 models, the MA2806A supports spectrum mask measurements of the V band (50-75 GHz) to accurately determine characteristics of ultra-wideband signals. P1dB performance of better than 0 dBm as well as minimum sensitivity performance of -150 dBm/Hz (meas) can be achieved. Design, manufacture, and QA engineers can now measure extremely weak signals at V band frequencies that are typically missed by conventional measurement systems.

Precision Assembly of Systems on Surfaces (PASS)

Chemiresistors represent a powerful class of chemical sensors that can be readily integrated into any electrical system, can be miniaturized, are readily multiplexed, and take nearly zero-power to operate. One of the greatest limitations to these sensors is a lack of selectivity, which is the electronic equivalent of noise. Interference from large varying background signals, such as humidity, can compromise the sensor signal to a point where there is no useful data. To address this challenge, new ways to integrate molecular constructs into carbon nanotube compositions that produce enhanced selectivity to certain molecules or classes of molecules were investigated to increase the signal to noise level in chemical sensors.

Development of a Novel Electrospinning System with Automated Positioning and Control Software

Electrospinning is a nanofiber fabrication technique that has grown in popularity due to its potential in numerous biomedical applications. The process uses an electrical charge to draw ultrafine fibers from liquid polymer solution to form a non-woven fiber scaffold. The polymer fiber diameters can range from millimeters to as small as nanometers in scale.

Advanced Multifunctional Materials for High Speed Combatant Hulls

Currently small boat combatant design focuses primarily on speed and maneuverability. It would be advantageous to expand these capabilities to include reduced radar cross-section, and enhanced survivability to blast and ballistic threats for both the structure and warfighters.

Turbine Flow Meters: Technology-of-Choice for Measuring Critical Fluid Flow Applications

The aerospace industry has some of the most difficult operating conditions imaginable. Sensors of all kinds used in this industry must stand up to the environment and be able to perform under harsh conditions, fit in extremely tight spaces, and have electronics that can compensate for variable conditions in order to provide precise, repeatable results.
