Wheel Force Transducer

Aconcept wheel force transducer has been developed that can measure the forces and moments between a tire and a road on a High Mobility Multi-purpose Wheeled Vehicle (HMMWV or Humvee) driven under off-road conditions. The proposed wheel force transducer is an important step in correcting the gap in current tire testing and modeling knowledge to ensure that future off-road vehicle models and simulation efforts are conducted with confidence. In order to obtain tire characteristics over off-road terrain, cost-effective field test equipment was required.

Thin Film Fixes Flaws in Thermal Battery Igniters

Unlike alkaline batteries used in common consumer electronic items, thermal batteries are inert, solid-state devices that do not rely on liquid electrolytes, which can corrode or leak from their casings over time. Long shelf life and reliability make thermal batteries the most common device to power missile navigation and control systems.

14-Bit Analog-to-Digital Converter

The 14-bit ADS4149 from Texas Instruments (Dallas, TX) is a high-speed analog-to-digital converter (ADC) that delivers low power consumption and performance across wide signal bandwidths from DC up to 550 MHz. It features a maximum sample rate of 250 mega-samples per second (MSPS) and consumes as little as 275mW per channel at that rate, while offering 72.5-dB SNR at 100-MHz input frequency. Dynamic power scaling reduces power consumption to 215mW at 160 MSPS.

Chassis Mount Power Supplies

XP Power (Sunnyvale, CA) has announced the VCS series of chassis mount single output AC-DC power supplies aimed at cost sensitive industrial applications. The series comprises 50W, 70W and 100W models and are available with +5, +12, +15, +24 or +48 VDC outputs. A user accessible voltage trim control provides a +/- 10% adjustment of the output voltage allowing for the use of non-standard voltages or to compensate for cable losses. The VCS series accommodates the full universal input range from 90 — 264 VAC without derating, and can provide full output power from -10 degrees C to +50 degrees C without derating, and with derating to +70 degrees C. Start-up is from -20 degrees C.

Flat Panel PC

WinSystems (Arlington, TX) has introduced the PPC3-G-6.5, a 6.5" open frame, color, flat panel PC based on a PC/104-Plus single board computer (SBC) that operates from -20°C to +70°C. It includes a resistive touch screen integrated into an aluminum, corrosion-resistant chassis about 2" thick; the open frame chassis (without a front bezel) permits flexible mounting of the system for OEMs and integrators with content-rich applications. It is suitable for instrumentation, industrial automation, and control applications with tight system integration and minimal space requirements. The outdoor-use, 6.5" diagonal color TFT flat panel display features a resolution of 640 × 480 pixels, and a high luminance of 500 cd/m2 (nits) and uses two long-life CCFL lamps that are user-replaceable. The display has a contrast ratio of 600:1, while the screen offers an anti-reflective coating.
