This paper presents a MARG Sensors based walking motion analysis method that can be used for rehabilitation treatment evaluation under ambulatory conditions in daily lives. A commercial inertial measure unit MTx is fixed on human shank segment. Then digital data box worn on the waist transmits the raw data to laptop with Blue-tooth for post processing.(More)
This paper presents a wearable sensor approach to motion measurements of human lower limbs, in which subjects perform specified walking trials at self-administered speeds so that their level walking and stair ascent capacity can be effectively evaluated. After an initial sensor alignment with the reduced error, quaternion is used to represent 3-D(More)
Gait analysis has become a research highlight. In this paper, we propose a computing method using wearable MARG (magnetic angular rate and gravity sensor arrays) with wireless network, which can calculates absolute and relative orientation and position information of human foot motion during level walking and stair climbing process. Three-dimensional foot(More)
The asymmetric unit of the title compound, {[MgNa₂(C₁₀H₄O₈)₂(H₂O)₈]·2H₂O}(n), contains one octa-hedrally coordin-ated Mg(II) atom (site symmetry 2/m), one octahedrally coordinated Na(I) atom (site symmetry 2) and one half of the dihydrogen benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligand, the second half of the ligand being generated by a twofold rotation(More)
In this paper, a new method of human motion segmentation is proposed, which the inertial data of human movement was acquired through wearable Inertial measurement unit (IMU), and the feature of raw time series data was directly extracted, which was segmented by sliding window, and then by combining Support Vector Machines (SVM) classifier as the algorithm(More)
Human walking contains important physiology, kinematic and dynamic information. There are many application prospect of human gait analysis in real life, such as monitoring the patient's recovery progress in clinical practice, the control strategy of bionic robot, etc. A wearable gait analysis platform (GaitSense) has been established based on wearable(More)
