Traveling-Wave Wide-Band Microstrip Antennas

Microstrip antennas that can be made to perform well over relatively wide frequency ranges but are mechanically and electrically simpler than prior such antennas have been invented. These antennas are designed to support traveling waves, in contradistinction to being designed traditionally to support standing waves. The exploitation of traveling waves to enable wideband operation is not new in itself; the novelty of the present invention lies in the electrical and mechanical antenna configuration for supporting traveling waves.

Spintronic Effects in Semiconductor Nanostructures

Progress has been made in calculation of spintronic effects in semiconductor nanostructures. The calculations contribute to the body of theoretical knowledge complementing recent experimental advances in generating, transporting, and detecting coherent spin-polarized populations of electron and nuclear spins in semiconductors. The experimental advances have demonstrated that spintronic effects could be harnessed as the basis of novel nanoscale devices. Theoretical advances are needed to understand and extend the experimental advances by enabling inference of previously unknown phenomena from results of experiments and incorporation of these phenomena into realistic models of operation and performance of spintronic devices, including devices that could be used in quantum computation.

Fanless Single Board Computer ( ADLINK Technology)

The NuPRO-796 from ADLINK Technology (Irvine, CA) is a half-size board computer featuring an AMD GeodeTM GX 533 processor. Fanless, the device has a 1.1 W CPU power consumption, and includes an on-board 128 MB memory on a single SODIMM slot, one UltraATA 66 IDE connector, and four Serial ATA connectors with RAID support. With several display options, it supports VGA/CRT monitors (1,600 ×1,200, 16 bbp at 85 Hz or 1,280 ×1,024, 24 bpp at 85 Hz), TFT LCDs, (1,280 ×1,024 bpp), and LVDS. Key I/O interfaces include an ACPI-compliant 10/1000BASE-T LAN port, four USB 1.1 ports (two USB ports on the faceplate, two by the pin header), and integrated audio controllers with an AC'97 interface. Operating temperature ranges from 0 to 60°C (storage temperature is -20 to 80°C).
