The purpose of this study is to determine the sleep status of college students. 12 volunteers(mean ± SE: 22 ± 2 yr, 170 ± 10cm, 61 ± 16 kg) take part in the research. The sleep situation are got by the waistband sleep monitor system. The average heart rate of the whole night, the average breath rate of the whole night, bed time, get up time, onset latency, total sleep time are monitored. These important...
Battery management system has a very extensive application field. This paper introduces an online system which is available for monitoring electric current, voltage and temperature of power battery group simultaneously. This system adopts the microcontroller and PC as the main controllers, collects the information like voltage, current and temperature of the battery with battery information collection...
For purpose of information management of film capacitor production workshop to provide convenience for production department management to grasp the production realtime data, in this paper, we design a film capacitor production monitoring system adopting the man-machine interactive information collection technology based on data acquisition and wireless network transmission. By the technology, we...
Taiyuan graben basin has been suffering serious ground deformation due to the combined effects of groundwater pumping, ground fissures and faults. However, most ground deformation monitoring mainly focus on the single city, thus it is difficult to reveal the regional extent of the deformation. Fifty-five ALOS/PALSAR images acquired from three adjacent tracks from 2007 to 2011 are used to obtain annual...
This paper presents a multi-functional marine environment monitoring system based on optical fiber transmission, analyzes the major hardware and software. This system has the functions of real-time detection, visual inspection and sampling inspection.
It is conductive to discover the fire or smoke leakage in the monitor region that detecting the smoke area clearly. Firstly, an adaptive LOG algorithm of smoke detection based on energy difference is proposed by the paper. After detecting the enhancement smoke area by energy difference between frames, dynamic accumulation, filtering and extracting smoke leakage position will be performed. The experiment...
To detect the residue of polycyclic aromatic hydrocarbons (PAHs) in the environment quickly by immune method, preparation of high quality antibody against PAHs is the most critical step of the project As the first step toward developing sensitive enzyme linked immunosorbent assays (ELISAs) for selective detection of anthracene in environment, a new hapten was synthesized by the Friedel-Crafts acylation...
