Linear Plasma Actuator for Dynamic Stall Control
Ionizes and Controls Air Flow to Improve Helicopter Wing Performance This helicopter wing flow control device deploys a plasma actuator with a linear counter-flow point embedded electrode design to force airflow around curved surfaces to counter dynamic stalls. Dynamic stalls occur when a wing loses lift at a high pitch rate. These undesirable events...

Foldable Polymers as Gene Probes
Abstract This technology utilizes novel probes to detect and identify target biomolecules in a sample. These probes employ conformational changes induced by molecular recognition events to initiate changes in the optical properties of the probe (e.g. the modulation of a fluorescence or absorption response upon target binding). Methods, including solid...

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...

Molecular Supracence based technologies
Unmet Need: Enhanced spectral resolution in fluorescence imaging Fluorescence based technologies are the current method of choice for minimally invasive imaging. However, the fluorescence imaging is limited to about four colors since it lacks wavelength multiplexing due to exceedingly broad bands. This issue is unresolvable within the fluorescence...

Distributed Feedback Fiber Laser Pumped by Multimode Diode Lasers
Researchers at the University of Arizona College of Optical Sciences and Canada's Carleton University recently succeeded in fabricating high reflectivity (>99%) Fiber Bragg Gratings (FBGs) into phosphate glass fibers using UV light and a phase mask technique. With this new manufacturing technique, fiber lasers can be created as single monolithic...

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...
