In this paper, we propose a muscle gesture-computer interface (MGCI) system for a five-fingered robotic hand control employing a commercial wearable MYO gesture armband. Eight channels of surface EMG (sEMG) signals were acquired and segmented. Then four levels of Daubechies 5 Wavelet family were performed to analyze the EMG signal. Totally 72 features were extracted from the EMG raw data for 16 hand...
To detect human sex from complex background, illumination variations and objects by machine is very difficult but important for adaptive information service. In this research, we present a preliminary design and experimental results of gender recognition from walking movements that utilizes gait energy image(GEI) with denoised energy image(DEI) pre-processing as support vector machine(SVM) classifier...
This paper presents a high-speed directional relay for EHV transmission line. The basic principle of the directional relay is based on comparing high-frequency component energy of directional traveling waves of each bus outgoing line. The relay comparison scheme is designed with intrinsic mode function (IMF) from empirical mode decomposition. The IMF is used to extract transient features from fault-generated...
This paper presents a design and partial implementation of an embedded system as a part of neural-machine interface (NMI) for neural-controlled artificial legs. We have designed a circuit consisting of 30 analog inputs for sampling signals from 16 EMG (Electromyography) electrodes, a 6 degrees of freedom (DOFs) load cell, 5 force sensitive resistors (FSR), and 3 goniometers. The amplified signals...
