This paper presents the design, implementation and experimental results of an energy harvesting system to extract energy from power transmission lines. The energy is extracted from a high permeability core clamped on a high alternative current cable. A coil wound on the magnetic core can harvest energy effectively from the power line when the core is operating at the non-saturation region. Little...
In this paper, a superconducting augmented rail-type electromagnetic launch system (SAREML) is proposed due to its inherent advantages in terms of lower current, smaller rail ablation, higher propulsive force, and higher energy efficiency. A superconducting coil to enhance the magnetic field was designed and analyzed. The inductance was calculated using the finite element method. Then, the mathematic...
Con Edison experiences more than 1000 arcing faults on its secondary distribution system each year. Arcing faults introduce strong harmonics into the power network. We propose a fast, low cost, and high performance approach to localizing arcing faults based on harmonics. First, we implemented 2 novel algorithms. One is based on voltage ratio of harmonics. This method can detect arcing fault one at...
Embedded DRAM will play a much larger part in IBM server microprocessors for new SOI technologies. Etch of a deep trench (DT) into the substrate, which is used to form the capacitor, is a complicated multi-step process. One of the key elements is etch of the buried oxide layer. Voltage contrast (VC) inspection is used to detect defective DTs and can differentiate between opens in the buried oxide...
