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...

Core loss suppression with sustained soft magnetic properties in ferromagnetic metal - ferrite composites for high frequency inductor applications

INV-20096 Background We face many technological challenges related to wireless communication and the rapid transfer of large amounts of data. Major advances in addressing these challenges are being driven by the advent of 5G (and, soon to be 6G) revolution. To meet 5G requirements and performance demands, new materials are required to resolve...

Deep field penetration in transcranial magnetic stimulation (TMS) via magnetic flux concentrator and strategic excitation coil placement

INV-14084 Background Transcranial Magnetic Stimulation (TMS) is a method for noninvasive, non-contact stimulation of neurons in the brain by magnetic induction of electrical currents. The TMS devices currently available on the market provide superficial stimulation due to the rapid attenuation of the field. Deeper penetration can only be achieved...

Concurrent eddy current loss suppression and sustained permeability using trace amounts of highly insulating magnetic integranular inclusions

INV-18034 Background One approach to reduce eddy current loss is to restrict the flow of eddy currents by increasing the resistivity of the material. For this purpose, insulating oxide particles (e.g., CaO, SiO2, Nb2O5, Ta2O5, HfO2, ZrO2, and V2O5) have been shown to preferentially increase the grain boundary resistance of polycrystalline ferrite...

Multifunction ferrite nanoparticles for targeted ultrahigh resolution imaging and concomitant magnetohyperthermia of cancers

INV-19038 Background Magnetic resonance imaging (MRI) has been vastly used in medical diagnoses of many diseases. According to the Organization for Economic Cooperation and Development, in 2016, 12% of the population in the United States have received an MRI (i.e ~ 38 million MRI scans) among which approximately 70% of those (i.e ~ 27 million) were...

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...
