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...
This paper reports the application of test structures to the evaluation of tantalum nitride (Ta-N) as a material for integration with high temperature electronics. The test structure fabrication involves the reactive sputtering of Ta-N and its consequent annealing in a vacuum to reach the target specifications of low temperature coefficient of resistance (TCR). A test wafer has been designed to both...
Three-dimensional (3D) modeling of CMOS active pixel image sensor from process to opto-electronic response is reported in this work. Process simulation is performed by Crosslight CSuprem while the optical effect is simulated by finite difference time domain technique and the electronic response by 3D drift-diffusion software APSYS. The electronic responses are presented versus various power intensity...
In power distribution networks, impedance short-circuit faults are hard to detect in their incipient stage, as the fault currents may not be large enough to trip circuit breakers. In this paper, we summarize our research activities in short-circuit fault localization in underground power distribution networks. First, a simulation testbed was built. It can emulate power distribution networks with both...
An Ultra Low Power (ULP) biomedical System-on Chip (SoC) has been developed for efficient ECG/EEG signal processing in a Body Area Network environment. This experimental SoC explores the use of event-driven peripheral modules that autonomously interact with external sensors together with the use of an Application-Specific-Instruction-set Processor (ASIP) to optimize energy-efficiency during active...
Multi-sensor image registration is a challenging task in remote sensing. Considering the fact that multi-sensor devices capture the images at different times, multi-spectral image registration is necessary for data fusion of the images. Several conventional methods for image registration suffer from poor performance due to their sensitivity to scale and intensity variation. The scale invariant feature...
A kind of system architecture based on multi-agent is proposed in this paper for autonomous control system of an autonomous underwater vehicle (AUV). The autonomous control system is divided into several agents according to its software function and hardware structure. Each agent is designed as a deliberative/act hybrid mode. The agent not only recognizes science events and makes decision unattached,...
