Time-Lapse Light Field Photography With a 7 DoF Arm

Overview Robots that have an arm for gripping and grasping may be asked to pick up objects with a wide variety of shapes, weights, sizes, and colors. One particularly challenging job for a robot is to grasp shiny or transparent objects, whose translucence or reflections may fool the robotic vision system. Tellex and colleagues invented a robotic arm...

Probabilistic Object Models for Robust, Repeatable Pick-and-Place

Overview Picking up an object is one of the simplest tasks a person can perform. For a robot, however, such a task requires a suite of surprisingly complex abilities. The machine must have a capable grasping hand capable of exerting just the right amount of force—enough to avoid dropping the object, but not so much as to crush it. The robot must...

Self-neutralizing air-breathing thruster and method of neutralization

An ion-engine is the cutting edge for atmospheric air-breathing engines. The technology depends on ionizing and neutralizing atmospheric air particles which create thrust. This unique possibility makes it an ideal choice for very-low-orbit satellites. Very- low-orbit satellite capabilities have benefits such as higher resolution for images, weight...

Non-Invasive Plasma Discharge Tube Device for Treating Brain Tumors

Treating brain tumors, like glioblastoma, is challenging. Current glioblastoma drugs, Rapamycin and Temozolomide (TMZ), generally only extend life for a matter of months, are not very effective in treating recurring tumors, and have significant clinical toxicity. A novel Plasma Discharge Tube (PDT) device has the potential to be more effective and less...

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...

Cold atmospheric plasma-stimulated media for treating cancers

For successful cancer therapy, the most important aspect is selective eradication of cancer cells without damaging healthy cells. Cancer cells and normal cells have different thresholds for tolerance of reactive oxygen species (ROS) and reactive nitrogen species (RNS) before cell death (apoptosis) is induced. Previously, GW researchers invented a cold...

Diagnosis of lung cancer subtypes using rapid molecular test

New cancer subtyping system can improve treatment options without disrupting clinical workflow.Problem Lung cancer is the leading cause of cancer death, with over 100,000 people dying per year.1 As most tumors are inoperable by the time the cancer is detected, patients are increasingly being placed on tailored treatment regimens. Prescribing targeted...

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...
