This paper introduces a virtual sEMG prosthetic hand development system based on LabVIEW. The system is aimed at finding proper method to correctly and promptly discriminate hand motions via sEMG. Waveform Length has been proved effective as extracted feature in this paper due to its high performance and short computing time. A back-propagation Neural Networks(BP Networks) is chosen as classifier...
This paper presents a new approach for visualizing the surfaces from 3D ultrasound data. 3D ultrasound data usually contain substantial quantity of speckle noise, which makes the extraction of smooth and continuous surfaces extremely difficult. In this paper, combining the partial differential equation model of anisotropic diffusion filter with the Lee filter, we present a new algorithm for handling...
In this work microwave cavity perturbation method and the DSP technology is implemented to estimate glucose concentration. Different concentration of glucose solution makes different resonant frequency and decaying in power in microwave cavity due to the perturbation. We use the Finite-Element method software ANSYS 11.0 to simulate the relationship between the concentration of glucose solution and...
This study aimed to evaluate the functional connectivity between cerebral regions by measuring the phase synchrony of magnetoencephalographic (MEG) signals elicited by regular simple tones and their duration-deviants in a mismatch paradigm. Significant synchrony was clearly identified between the temporal and ipsilateral frontal region following the auditory stimulation. This temporal-frontal interaction...
This study aimed to characterize buttock pressure during 0, 15, 25, 35 degree posterior sitting posture in children. In order to make sure which tilt is perfect for buttock pressure for children with wheelchairs. This study utilized Force Sensory Array to assess changes in buttock pressure during 0, 15, 25, 35 degree posterior tilt sitting posture. One-way pair T tests was used to assess underlying...
A new method to design the wireless power transmission technology for medical endoscope is suggested. Discrete multiple coil structure with a driving system possessing the function of site-site wireless power transmission is adopted as the transmitting coils. Only the one that couples best with the receiving coil is selected to be driven to transmit power for medical endoscopes. It's theoretically...
Proprioception should be necessary for the trunk balance and skillful movement. However, proprioception deteriorates due to aging and spinal cord injury. Training for the recovery of proprioception is required because of the ADL and prevention of overturning. We have developed a new rehabilitation support system for “sensory training”. The purpose of this study is to perform clinical trials with 2...
In this study, a modified topology-adaptive snake (T-snake) is proposed for the segmentation of ultrasound image. The algorithm was improved as follows. First, the image is decomposed in the place which has offset from pixel's position while snake points are in pixel's position. This will reduce the task during calculating intersections between contour and ACID grid. Second, the rule to process topology...
Objective: To investigate the effects of low frequency whole body vibration on preventing the bone loss of rats' lower limbs induced by tail suspended. Method: 40 male rats were divided randomly into 4 groups, including tail suspended group(sus, n=10), tail suspended + ground stimulus group (s+g, ground stimulus: 30min/d, 5d/w, n=10), tail suspended + vibration group (s+v, vibration stimulus: 45Hz,...
The air combat process is regarded as the discrete event dynamic system which is composed of a series of discrete-states, and its discrete state sub-model is established. In order to choose the tactical maneuver, the evaluation function is constructed by the air combat situation index and the air combat capability index. Combining with the 3 degree-of-freedom (3DOF) aircraft model, the maneuver command...
The HHT (Hilbert-Huang Transform) method is adopted to decompose the pulse signals synchronously from the carotid and wrist arteries both in healthy people and those patients suffering from coronary heart disease into the different mode orders. Based on the cross-correlation analysis, it is statistically found that quasi-cycles of 2nd-modes from healthy objects correspond respectively to 1/3 of their...
This paper improves Biomimetic Pattern Recognition based on Hyper Sausage Neuron and applies it in the study of Motor Imagery EEG recognition. The paper uses the datasets from previous Brain-Computer Interface Competitions to test the accuracy and efficiency of the results, and compares them with those of SVM and BP. The results show that: with sufficient training set, the performance of Biomimetic...
To improve the surface biocompatibility of titanium films, a electrostatic self-assembly technique (ESA), based on the polyelectrolyte-mediated electrostatic adsorption of chitosan (Chi) and heparin (Hep), was used leading to the formation of multilayers on the titanium thin film surfaces. The film growth was initialized by depositing one layer of positively charged poly-L-lysine (PLL) on the NaOH-treated...
