In this article, a design of non-contact sensor which is based on PCB (Printed Circuit Board) antenna for monitoring physiological parameters is proposed. In order to remotely monitor the activities of heartbeat, respiration and body movement, this article designed and implemented a Yagi patch antenna whose working central frequency is 2.45 GHz. The gain of the original antenna is 8.1 dB. Considering...
With the deep mining development of coal resource, many safety problems have arisen and become serious gradually, such as tunnel deformation, rock burst, and so on. Multi-source techniques and methods must be used to monitor and study the behave laws of tunnel pressure, thus safety and efficient mining can be guaranteed. It takes the working face No. VI 15-22020 and its transportation tunnel of 2nd...
In clinical applications, the liquid of high-pressure syringe sometimes leak out of vein due to rapid injection speed and high pressure. Based on Texas Instrument's microcontroller MSP430FG4619 and Measurement Specialties Inc's pressure sensor FS2050, designs a diversion and alarm system to prevent the leakage of high-pressure syringe. The system offers the real-time monitoring for the full injection...
The condition-based maintenance (CBM) technique has been widely used in the power plant in China. Feed water pump is one of the most important general requirements in the power plant. Its reliability plays an important part in the safety of the complete running. On the basis of practical situation in one power plant, a system for condition-based maintenance of the feed water pump in said power plant...
