An absorptive common-mode filter (A-CMF) embedded in a four-layer printed circuit board is proposed. Unlike traditional CMFs, for the A-CMF, common-mode (CM) noise is absorbed through the surface mount resistor, so the transmitted and reflected CM noises can be suppressed simultaneously. The proposed A-CMF is synthesized and implemented based on the corresponding equivalent circuit model. To achieve...
An absorptive common-mode filter (A-CMF) using mushroom-like structure will be proposed to embed in a four-layer PCB. In this structure, common-mode (CM) noises will be absorbed by a resistor, which means that the transmitted and reflected noises will both be suppressed. The proposed structure is invented and implemented based on an equivalent circuit model, for which modeled elements will be derived...
In this paper, we propose a gait tracking and analysis method using a depth image sensor installed on robotic walker. Nowadays, robotic walker not only can assist elders who have suffered deteriorating mobility but also help to provide rehabilitating function to people who have crippled walking ability. This approach is meant to be sufficiently accurate, non-intrusive, and low-cost. The goal of this...
In VANETs, the carry-and-forward strategy had been adopted to overcome uneven distribution of vehicles. If next vehicle located in the transmission range, the vehicle forwards packets; otherwise carries packets until meeting. The carry is almost occurring in sparse traffic road segment, and long carry distance has long end-to-end packet delay. Likewise the dense condition also could have long delay,...
A new method based on sequential Monte Carlo algorithm is proposed for tracking multi-target and data association in non-linear system. The algorithm partitions the problem of multi-target tracking into two problems: single target tracking and data association. Single target tracking is implemented by using UKF and data association by using sequential Monte Carlo algorithm. Since Particle Filter has...
An accurate and practical method is proposed to predict the loop gain of buck converters with limited knowledge of their control circuits. This approach models the control circuits of buck converters as a simplified linear system based on a few measurements. Compared with other prediction methods, this approach obtains accurate loop gain Bode plots with much less information. Detail procedures of...
