Embedded Active Fiber Optic Sensing Network for Structural Health Monitoring in Harsh Environments
This optical fiber based distributed sensing system is able to monitor structure health, temperature and strain of the surrounding structure simultaneously in harsh environment of high temperature (1000 C). The distributed non-destructive evaluation is achieved by an all-fiber NDE structure and is immune to EMI and high temperature. And it can dete...

Cellulose Ethers for Solubility Enhancement
The technology is a novel method for making functional materials from sustainable, renewable polysaccharides. It focuses on making materials that have good solubility, dispersability, or otherwise have high affinity in and for water. These materials can be designed to contain virtually any functional group, thereby permitting the designer to equip ...

Islanding Detection Using Phase-Locked-Loop Small-Signal Instability For Three-Phase Power Inverters
A simple and effective anti-islanding detection is required to meet IEEE standard 1547 for every distributed generation unit. Many research papers and patents work on this issue, and there exists lots of solutions. All the existing solutions suffer the complicated design and lots of implementation procesess. Some of them tend to destabilize the gri...

Two-Stage Bi-Directional Single-Phase Converter with DC-Link Capacitor Reduction
It is well-known that single-phase ac-dc conversion requires a bulky dc-link capacitor for filtering the ripple power from the grid, thus leading a overall bulky converter size. Also, in order to interface a dc renewable energy system to a single-phase utility grid, bi-directional power flow control and dc-bus voltage regulation are major concerns....

DC Leakage Current Reduction for Single-Phase Full-Bridge Converter
The switching-frequency dc leakage current issue exists in the single-phase full-bridge topology with the unipolar modulation switching scheme. It is important to reduce the leakage current, which has a negative impact on the solar panels. With the emerging market on solar inverter, there are lots of patents filed by different companies on solving ...

Near-ideal (colossal) Magnetoelectricity in High-Permeability Magnetostrictive/Piezo/Fiber Laminates
Manetoelectricity is the interaction between the polarization and manetization subsystems of a solid. Giant mangeto-electric (ME) effects are known in laminate composites of magnetostrictive and piezoelectric layers, which are orders of magnitude higher than those of single phase systems. Theoretically, the longitudinally-magnetized longitudinally...

DCR Current Sensing Method for Adaptive Voltage Positioning in Coupled Inductor Voltage Regulators
The conventional current sensing method with sensing resistors produces additional losses and decreases the efficiency in the multiphase DC-DC converters with coupled inductors. A novel lossless current sensing method in multiphase DC-DC converters with coupled inductors is proposed. With this novel method, the additional loss is saved and the ef...
