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...

Gamma Ray Imaging System for Rapid and Precise Detection of Radioactive Materials from a Distance

This invention is a gamma detection system that determines the position and energy of gamma sources within its field of view without using a pixelated full-energy detector. In addition, the present gamma ray imaging systems utilize coincidence measurements, which reduces the background level compared to systems that do not use coincidence methods to...

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...

Flagmor transgenic mouse

Summary FLAGMOR transgenic mice provides an advantage to studying signal transduction of mu-opioid receptors (MOR) through the activation of potassium-ion channels, desensitization, and receptor trafficking. Technology Overview Mu-opioid receptors are a class of G-protein coupled receptors found primarily in the CNS and the GI system. The activation...
