SNMF – An On-the-Fly, Multi-Filament Single-Nozzle for 3D Printing
A printing system with a single nozzle/printhead that can dispense multiple materials in a controlled manner. Problem: Multi-material additive manufacturing transcends the limitations of traditional manufacturing processes by allowing the fabrication of complex, functionally graded components with tailored material properties. However, limitations remain...

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...

Acoustic Detection of Transverse Defects in Rail at High Speed
Invention SummaryDevice, method or vehicle that uses acoustic detection techniques which operate on the principal of acoustic emission (AE). Two sensors generate an acoustic signal representing contact between a train and a rail and generate an output as well. A processor compares the outputs received from both sensors and a location sensor generates...

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...
