Two suitable coordinate systems overlapping at the origin were established to estimate orientation by computing the spatial relationship between them. An Inertial Measurement Unit sensor (IMU), consisting of a tri-axial gyroscope and tri-axial accelerometer was used to define reference systems. This work describes an algorithm to estimate the orientation of an object in 3D space through the optimal...
This paper presents two methods for the classification of six different hand motions based on the analysis of the transient state of surface multichannel electromyographic signals recorded from 10 normally limbed subjects. The signals were classified using the coefficients extracted from a discrete wavelet transform analysis. While the first method uses a feature vector based on the variance of the...
This work presents an algorithm for a shoulder model as a dynamic system to reproduce its movements. This proposal describes the range of motion of the shoulder through a coordinate system by using matrix rotation. Thus the shoulder motion is represented in a new coordinate system by a vector position. The reliability of the proposal algorithm was performed by making several tests on a healthy volunteer...
World fossil fuel reserve is expected to be exhausted in coming few decades. Therefore, the decentralization of energy production requires the design and integration of different energy sources and conversion technologies to meet the power demand for single remote housing applications in a sustainable way under various weather conditions. This work focuses on the integration of photovoltaic (PV) system,...
