Beacon Deployment
The Beacon Deployment is a deployment release system for low, relief, and self-orienting payloads, such as beacons, markers, hydrophones, sensors, mines, munitions, and communication modules from marine vehicles. Utilizing a vacuum base mechanism, compared to a mechanical one, the release is capable of reducing noise associated with release activities....

Light Fiber Tether Management for Underwater Vehicles
­A self-retracting reel for fiber and light-tether payout management from underwater vehicles or host platforms. The designed reel holds a communication tether, and an active drive system designed to maintain minimal but sustained tension on the tether at all times. The reel speed and direction is dictated by fluctuations in the tether tension and...

Rapid Seeding Spool
The Rapid Seeding Spool is effectively designed to reduce operation and labor costs in maricultural farming. The spool uses two thrusters to propel and evenly rotate around the seed string at a specified number of wraps per distance. The seeding can be done underwater and reduces the time seed spools spend in the air; this reduces exposure time to the...

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...

Functionalized Porous Polymer Nanocomposites via Introducing Functional Components into Emulsion Systems
AbstractFunctional porous polymer films are of great interest to academia as well as industry for a variety of applications, such as gas separation, water purification and sensors. A porous structure can not only reduce the density of the material, but can also remarkably increase the surface/interface area, which can be used for various functionalizations....

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...
