Design of a flyback switch mode power supply for multichannel electrophysiological stimulators / 中国医疗器械杂志

In order to supply the multichannel electrical stimulator, a DC-DC flyback switch mode power supply based on a high-performance current mode controller UC3845 has been designed. The experimental results indicate that the power supply has satisfied the demands and can supply the multichannel electrical stimulator and similar apparatuses.

Design of a wireless fetal electrocardiogram monitoring system based on S3C2410 / 中国医疗器械杂志

This paper introduces a new fetal electrocardiogram monitoring system based on S3C2410 and telecommunication, and its framework and flow chart. Based on the genetic algorithm, the improved IIR adaptive filter achieves the non-invasive, real-time extraction of FECG. The system provides the reliable gist for the diagnosis of fetal congenital diseases. FECG extraction, S3C2410, telecommunication, genetic algorithm, IIR adaptive filter.
