The Evolution of Storage

The embedded computing industry is being inundated with changes to storage products driven by technological advancements, market forces and environmental concerns. The precipitous drop in solid-state flash drive (SSD) prices has enabled designers, previously turned off by the cost, to now consider solid state as an option over rotating hard disk drives (HDD). With that decision comes a serious list of performance benefits, including improvements in durability and security, which SSDs have over HDDs.

SPBooth 423

New Scale Technologies (Victor, NY) has introduced the SQL-1.8 SQUIGGLE piezoelectric linear motor that travels up to 7 mm per second and pushes axial loads of up to 30 grams. It measures 1.8 × 1.8 × 6 mm. New materials and thread design in the linear drive screw enable high-volume automated manufacturing. The motors feature high efficiency, force, and precision, and are used for miniature optics and imaging, surveillance, electronic locks and fasteners, micro UAVs, gun sight stabilization, and microfluidics (lab-on-a-chip pumps and valves). A patented ultrasonic motor uses less power than electromagnetic micro-motors.

Micro Air Vehicles Serve as Eyes in the Sky for Ground Troops

Honeywell Aerospace has developed the Micro Air Vehicle (MAV), an unmanned aerial vehicle (UAV) based on ducted-fan technology that recently was deployed in Iraq to identify improvised explosive devices (IEDs) from the sky. The deployment marked the first time a ducted-fan UAV was used during combat missions. The MAV, and subsequent generations of the vehicle already in use, could change the face of military reconnaissance, as well as help civilian law enforcement and aviation officials.

Network Keeps Line of Communication Open to Convoys

An airman riding as part of a convoy escort team in Iraq keys his radio microphone to check in with his base, and hears nothing but dead air. The U.S. Air Force is leading a joint implementation of a Radio over Internet Protocol Routed Network (RIPRnet) communication system that prevents such a scenario. RIPRnet ties convoy radios in with Internet-based technology to extend their range, providing robust, clear, reliable, and secure communications for soldiers, sailors, airmen, and Marines who are out on the roads of Iraq.

Protection Schemes for Advanced Shipboard Electrical Systems

A research program has made progress toward the development of schemes for protection against faults in next-generation DC zonal shipboard electrical systems (DC SESs) and for configuration management in these systems to enable surviving parts of the systems to continue to distribute electric power to critical loads. Computational simulations of a representative prototype DC SES have shown that these schemes could afford protection at a system level (in contradistinction to a local level), thereby imparting, to the DC SES, an intended capability for self-healing.

DC Power Converter for 200°C Containing SiC Transistors

A DC-to-DC power converter, nominally rated for a power of 180 W, an input potential of 28 V, an output potential of 270 V, and a maximum operating temperature of 200°C has been designed, built, and tested. This power converter serves as a prototype for further development of power converters required to be capable of operating in high-temperature environments in diverse settings, including automobile, aircraft, and spacecraft engines, and oil and gas wells.

Simulation of a Flywheel Energy-Storage System

A computational model has been developed to simulate the operation of a laboratory flywheel energy-storage system that is a subsystem of the Flywheel Attitude Control, Energy Transmission, and Storage (FACETS) system located at Kirtland Air Force Base in New Mexico. The FACETS, which includes three advanced flywheel energy-storage units and an apparatus denoted the Agile Multi- Purpose Satellite Simulator (AMPSS), is used to demonstrate conceptual spacecraft operations involving integral combinations of attitude-control maneuvers and energy-storage operations. The flywheel units include high-hoop-strength carbon composite rotors that turn on magnetic bearings. The flywheels have a maximum rated angular speed of 40,000 rpm, making it possible to store as much a 1 kW·hr of energy in each unit. An air bearing supports the entire AMPSS test article allowing three-axis rotation with minimal damping. In addition to the flywheel units, the system includes DC-to-DC power converters and a three-phase rectifier.
