Design of Electromagnetic Tracking System Using Rotating Magnetic Field Based on DSP / 中国医疗器械杂志

This paper realized an electromagnetic tracking system based on electrically-controlled rotating magnetic field. A tracking system using the digital signal processor (DSP) as the control processing device was developed, including a controllable constant current source module, a magnetic field source module, a three-axis magnetic sensor and ADC interface circuit. The experimental results verified that each time the system could be stable positioning, average error of position was 0.282 cm, the average error of orientation was 0.696o, the positioning time was 1.572 s. Through calibration and further improvement of the hardware circuit, the performance of the system is expected to further improve.

DSP-based design of family health monitor / 国际生物医学工程杂志

Objective To design a new portable vital signs monitor for family use. Methods TMS320F2812, a kind of digital signal processor, was applied as the main processor to control the functional mod-ules including A/D convertor, LCD display. Bluetooth communication module was introduced to achieve real-time fast transfer of data between the system and the PC. Results Not only can the system monitor electrocardiogram (ECG), breath rate, pulse rate, body temperature and other vital signs accurately, but also it runs stably. Conclusion The features of DSP and Bluetooth were well combined in the design of the family-oriented, easy to use, multi-functional monitor with small size, low power consumption and convenience. A broad application and market prospects can be predicted.

DSP-based real-time high-speed data acquisition and process system for biomedical signal / 医疗卫生装备
