Surface electromyogram (sEMG) signals have been used to control multifunctional prosthetic hands. Researchers usually focused on the use of several channels with sEMG identify more gestures without limiting number sensors. However, residual muscles an amputee are limited. Therefore, point a successful recognition system is decrease classify gestures. To achieve this goal, we proposed novel gesture system, in which three can nine In time domain features, root mean square ratio, and...

Treadmills are widely used to recover walking function in the rehabilitation field for those patients with gait disorders. Nevertheless, ultimate goal of recovery is walk on ground rather than treadmill. This study aims determine effect treadmill and upper trunk movement characteristics using wearable sensors. Eight healthy male subjects recruited perform 420-m straight overground (OW) 5 min (TW), wearing 3 inertial measurement units a pair insole In addition common linear features,...

The hand plays a very important role in our daily life, and the amputees suffer lot from loss of hands or upper limbs. Hence, assisting devices are desired urgently. Today, prosthetic based on surface electromyography (sEMG) signals can recognize many gestures, but some problems still exist. To identify more recognition systems require multiple electrodes, which unable to be applied with less residual muscles. Meanwhile, better computing performance is required as number electrodes...

For about 1800 years, tongue inspection has been one of the four major diagnostic methods in Traditional Chinese Medicine (TCM). The is believed to be able reflect health status human body. However, making an accurate diagnose with not a trivial task. It usually requires enormous training on TCM doctor before he can make reasonable diagnosis. Recently, image processing have proposed automatically process images and This study proposes k-means clustering adaptive active contour model based...

The ship heading control is very important to the shipping industry. Active Disturbance Rejection Control (ADRC) method ideal for control, but it highly correlated with parameters. In this brief, we employed chaotic mapping and fractional derivative update enhance Grey Wolf Optimizer (GWO), namely Improved GWO (IGWO). IGWO proposed tune parameters of ADRC adaptively, then IGWO-tuned utilized heading. As comparison, four other optimizers are also ADRC. Five different disturbance situations...

Surface electromyography (sEMG) signals have been applied widely in prosthetic hand controlling. In the sEMG signal acquisition, wireless devices bring convenience, but also introduce missing due to interference or failure during data transmission. The may only last for tens of milliseconds, a great impact on recognition. Researchers employed various methods complete data, completed not totally fit origins, and more extra calculation time will be spent. When recognizing gestures by from few...

The distillation process plays an essential role in the petrochemical industry. However, high-purity column has complicated dynamic characteristics such as strong coupling and large time delay. To control accurately, we proposed extended generalized predictive (EGPC) method inspired by principles of state observer proportional-integral-type method; EGPC can adaptively compensate system for effects model mismatch online performs well controlling time-delay systems. needs fast control, delay...

With complex functions, hand is an important organ for human. Unfortunately, many people in China are suffering from losing. Therefore, the effective motion recognition system required to help amputees live or work normally. The surface electromyography (sEMG) signal can represent effectively, and studies about sEMG-based prosthetic hands have been investigated. However, some use on-off switch control command, which limits intelligence flexibility of hands. Some intelligent systems require...

Stroke patients need rehabilitation to recover their abilities of moving, and the underwater can reduce possibility secondary injury during process. Collecting surface electromyography (sEMG) signals provide better guidance medical doctors. However, current sEMG electrodes cannot be applied collect underwater. To solve this problem, we propose a soft electrode based on conductive silicon. The time domain frequency features are extracted. identified by Back Propagation Neural Network (BPNN)...

Animal-robots have superior advantages over conventional robots. Nevertheless, the mechanism of animal's brain for motor control is still unclear and needs more investigation. Therefore, adult male Sprague-Dawley (SD) rats are chosen as rat-robots to investigate rat's turning behaviors based on electrical stimulation. In this paper, we rat through stimulating Somatosensory Barrel Field Cortex (SlBF) area brain. order find out relationship between different parameters stimulation behaviors,...
