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...

Voltage Sweep Ion Mobility Spectrometry
AbstractIon mobility spectrometry (IMS), is a powerful tool commonly used for security applications (e.g. search for explosives, narcotics, and other trace contrabands) but it doesn’t achieve optimal separation power with both small and large ions simultaneously. Similar to the general elution problem of chromatographic experiments, small ions...

Non-Recirculating Roller Screw
This technology was developed as a key element of the camera focusing mechanism for NASA's OSIRIS-REx mission led by the University of Arizona, which was recently launched on a sample retrieval mission to the near-earth asteroid Bennu. This invention meets the demanding requirements of the OSIRIS-REx mission including high precision and reliability...

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...
