Immunoassay is one of the most important protein detection methods, which is widely used in clinical diagnosis, environment monitor and biological research due to its high specificity and sensitivity. Most of the existing protein immunoassay detection devices have the weakness of high expenses, large scale and low sample processing rate. Microfluidic immunoassay chips have been widely recognized as...
Electroencephalography (EEG) is the recording of electrical activities generated by nerve cells in the cerebral cortex. As the only non-invasive method for measuring brain activities from human scalp, it has been widely used in the area of medical diagnosis, neuroscience research, commercial application, etc. Most of the existing EEG acquisition systems, which are usually comprised of analog switches,...
A system of the signal acquisition and data processing used for light-emitting diodes induced fluorescence (LED-IF) detection in our laboratory was described in this paper. A high-speed data acquisition module was developed. The function of signal acquisition in real-time and data processing was realized utilizing the graphical programming environment LabVIEW. To reduce the distorted come from the...
Biomedical rehabilitation technology, especially tele-rehabilitation, surely plays an increasingly important role in future aging society. Meanwhile, ZigBee technology is an enhancement of IEEE 802.15.4 standard by giving a specific definition of the network layer and providing a series of functions for application layer in Wireless Sensor Network (WSN). Nowadays, ZigBee is being utilized in a wide...
Taking into account the complex interferences in underwater environment, this paper presents a neural network-based self-tuning PID controller for a spherical AUV. The control system consists of neural network identifier and neural network controller, and the weights of neural networks are trained by using Davidon least square method. The proposed controller is characterized with a strong anti-interference...
With the rapid development of space life science research, more functional instruments and equipment are required. Research on cell propagation and analysis is very important in the field of space biology. And cell transfer is a key technique in space station. If the cells can be transferred automatically, it can solve the problem of automatic processing of samples and component analysis of cells...
Eye movement is a direct expression of human's visual intent. The paper presents a novel system which is focusing on utilizing eye movement information as control source and the video streams from a remote pan-tilt-zoom (PTZ) camera as feedback. By processing left and right eye images simultaneously, the system can recognize the direction of eye movement and adjust the motion of remote PTZ camera...
This paper introduced a new way which utilizes genetic algorithm to optimize neural network weights. And we have worked out the algorithm on ARCGIS and MATLAB platform. Meanwhile, a comprehensive evaluation of environment carrying capacity on Jiulong county has been carried out. The findings and results show that this method can provide a new way to evaluate geological environment, because it can...
This paper presents detailed description of a real-time hand gesture recognition system using embedded DSP board and image processing approaches. Such a system which can identify hand postures and dynamic gestures has manifold potential applications range from sign languages to human computer interaction. We use Q6455 DSP board based on 4 TI-TMS320C6455 DSPs as the computational unit. This versatile...
