Architectures for Cognitive Systems

A need exists for small, autonomic systems in the battlefield. Autonomy allows the creation of unmanned systems to perform complex, high-risk, and/or covert operations in the battlefield without the need for constant human operation. Current computing systems are not optimized to perform intelligent operations such as environmental awareness, learning, and autonomic decisions in a size, weight, and power form factor that matches platforms envisioned for future use.

Circuit-Switched Memory Access in Photonic Interconnection Networks for High-Performance Embedded Computing

High-performance embedded systems, such as those found in aerial surveillance platforms and handheld devices used by the military, are of key importance. These systems are characterized by stringent power budgets and the need for extremely fast, streaming access to memory. While general-purpose processors offer a customizable solution, they typically do not meet the power and performance requirements for the systems in question. For this reason, specialized chip multiprocessors (CMPs) are used.

Analysis of Voltage and Current Signal Processing in a Li-ion Battery Management System

A Battery Management System (BMS) manages Li-ion batteries in a storage system for pulsed power weapons aboard Naval vessels. The system charges the batteries with a buck converter according to the Constant Current Constant Voltage method. The BMS uses analog equipment to measure signals and then digitally converts signals for transmittal to a Field Programmable Gate Array (FPGA).

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.
