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...

Biopsy Clip Metal Detector to Aid Breast Surgery
This metal detector localizes biopsy clips (e.g. titanium) placed at the site of breast tissue biopsies. The device is a handheld metal detector that can be inserted into a surgical incision to help locate small markers without an invasive procedure to insert a localizing wire, radioactive seed, or other localization technologies. The device is able...

Titanium Clip Metal Detector to Aid Breast Surgery
This handheld metal detector aids surgeons with localizing breast cancers, eliminating the need for invasive procedures. With the increased use of mammographic screening, breast cancer is more frequently detected as a radiographic lesion only rather than a palpable mass. This has made image-directed localization a necessity for surgical excision in...

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...
