Pulse Waves

During pulse signal collection, width information of pulse waves is essential for the diagnosis of disease. However, currently used measuring instruments can only detect the amplitude while can’t acquire the width information. This paper proposed a novel wrist pulse signal acquisition system, which could realize simultaneous measurements of the width and amplitude of dynamic pulse waves under different static forces. A tailor-packaged micro-electro-mechanical system (MEMS) sensor array was employed to collect pulse signals, a conditioning circuit was designed to process the signals, and a customized algorithm was developed to compute the width. Experiments were carried out to validate the accuracy of the sensor array and system effectiveness. The results showed the system could acquire not only the amplitude of pulse wave but also the width of it. The system provided more information about pulse waves, which could help doctors make the diagnosis.

A design of wireless pulse signal acquisition system for status monitoring of ship navigators has been presented. The system employs STC12LE5608AD as controller for timing acquisition of the pulse signal. And then the data are written to the register of CC2500 via SPI interface and transmitted. When the receiver takes the data, the MCU reads the data from the receiver register of CC2500. Finally the MCU send the data to computer via UART for display and further processing. Wireless transmission insures that the system can analyze the degree of navigators' fatigue objectively and quantifiably without affecting their operation of the ship. The system serves as a warning for fatigue navigation. This system has advantages of low power consumption and portability. It has the practical value of safe navigation of ships.
