Rabbits were narcotized and stimulated by 0.5Hz electric pulse. Potential of scalp was sampled at 3764Hz. Wave components of rabbit somatosensory evoked potential (SEP) can be located precisely through the method of continuous wavelet transform (CWT). Frequency feature of SEP can also be analyzed by CWT. The technique of continuous wavelet transform, which(More)
A photo-medical capsule that emits blue light for Helicobacter pylori treatment was described in this paper. The system consists of modules for pH sensing and measuring, light-emitting diode driver circuit, radio communication and microcontroller, and power management. The system can differentiate locations by monitoring the pH values of the(More)
This study was directed at extracting the rabbit somatosensory evoked potential (SEP), locating and analyzing the waveform of rabbit SEP. The rabbit was narcotized and stimulated by 0.5 Hz electric pulse. Potential of scalp was sampled at 3.764 Hz. Rabbit somatosensory evoked potential was extracted by one-dimension multi-resolution analysis, and continuous(More)
OBJECTIVE To extract rabbit somatosensory evoked potentials (SEP), by using a new technique named independent component analysis. METHOD The rabbit was narcotized and stimulated with 0.5 Hz electric pulse. Potentials at scalp was sampled at 3764 Hz. Response signals to repeated stimulations for 3 times mixed with background noise was acquired at the same(More)
