Although many wearable sensors have been developed or commercialized for gait analysis, ambulatory force sensors and motion sensors were rarely integrated to implement complete human dynamics analysis. Three-dimensional (3D) lower limb kinematic and kinetic analysis based on ambulatory measurements is introduced in this paper. We developed a wireless sensor system composed of a mobile force plate...
In clinical applications, the quantitative analysis of gait variability using kinematic and kinetic characterizations can be helpful to medical doctors in monitoring patient recovery status. A high-speed camera system and a stationary force plate can only accurately measure complete ground reaction force (GRF) and body orientations during a few steps, but data on successive gait measurements including...
Automobile industry requires 100% inspection of every electronic component used. If a wire bonding device has a failure rate of 1 ppm, it would have the consequence of 15 of 1000 cars would fail. In this paper, we propose a method for tracing and inspecting 3D wire loops in a sealed semiconductor device using X-ray CT. 3D primitives are detected in predefined planes with a subpixel transition detection...
A stationary force plate can only accurately measure complete ground reaction force (GRF) during no more than one stride, but the data of a successively measured multi-axial GRF in different environments is desired not only for researchers on gait analysis but also for clinical doctors. A wearable force plate system was developed by integrating small triaxial force sensors and 3D inertial sensors...
