Supersonic Jet Curtains for Control of Moments on Tailless Aircraft
The invention is a method to improve the design of tailless aircraft, such as the blended wing body design. The improvement consists of using high speed jets to create a supersonic jet curtain to provide flight directional controls. The jets are installed in the wings and are able to control the pitch, yaw, and roll of a tailless aircraft. Background:...

PMU-Embedded Analytics for Online Event Detection and Classification in Power Grids
The energy requirement of the world is increasing exponentially every year. With the power demand sites concentrated in the region with the highest population density, energy production sites must be located remotely. This isolation requires lengthy and complicated grids to be designed and manufactured to transmit power over long distances. Grid failures...

All-Fiber Multicore Fiber Laser Devices
Researchers at the University of Arizona have developed a compact, power-scalable, alignment-free fiber laser that takes a new approach to stabilizing phase-locked operation of multi-core fiber lasers by completely removing all free space optical components. This high-brightness, all-fiber laser package uses passive optical fiber spliced at both ends...
