Considerable scientific and technological effort has been devoted to develop implantable wireless stimulator systems for biomedical applications. The main purpose of such stimulator system is to provide electrical excitation to human body cells to help patient re-gain lost body function or rectify fault body function, in an elegant way that there is no notable cosmetic difference when patients are...
This paper presents a single-channel programmable muscle stimulator. The charge balance of the proposed stimulator is achieved using the concept of the dual-slope analog-to-digital converter (ADC). This approach negates the need for precise current matching between cathodic and anodic current, which is usually required in order to achieve good charge balance. In the dual-slope concept, the charge...
This paper presents a monolithic single-channel programmable nerve/muscle stimulator implemented in a 0.35μm CMOS technology. It consists of a 10-bit current output digital-to-analog converter (DAC) to generate the required cathodic and anodic currents, and a simple digital circuit to control the operation of the stimulator and its programmable stimulation parameters. The proposed stimulator produces...
Based on multiple kernel learning (MKL) support vector machine and decision tree combined strategy, a multi-class classification method is proposed to classify lower limb motions using electromyography (EMG) signals. According to the framework of multiple kernel learning, the MKL-based multi-classifier is constructed using binary tree decomposition method. Four-channel surface EMG signals are firstly...
With the rapidly growing use of digital images in medical archival and communication, image compression technology, especially diagnosis lossless compression technology, plays a more and more important role for medical applications. In this thesis, a novel diagnosis loseless compression algorithm is presented for digital mammography. The mammogram is divided into breast region, pectoral muscle and...
Compare the sensible perspiration & the change of body fat after dynamic exercise (aerobics) & complex static exercise (aerobics yoga). The results show that body fat decreased greater during complex static exercise than during dynamic exercise (P<;0.05). Though the changes between the body weights of the 2 groups weren't significant, complex static exercises decline of body fat greater...
