Monitoring sleep state and sending out alarm signal according to the state and the acute disease belong to the area of sleep basic research and prediction of outbreaks of diseases. The system includes:monitoring and analyzing the sleeper pulse's physiological parameters, the embedded computer judge whether or not the sleeper suffers acute disease(heart disease, cerebral haemorrhage, etc) . If so, the wrist pulse monitoring device sends the wireless alarm signal. When the bedside wireless receiver receives the alarm, it can send sound or telephone alarm. The sound alarm can explicitly tell nearby accompanists, the telephone sound alarm can give an alarm according to the telephone number set in advance, and inform relevant personnel, may also inform the 120 emergency center . At the same time, the bedside wireless remote devices open the door to wait for the arrival of emergency personnel. When acute diseases suddenly break at night, the system can effectively solve the patients emergency treatment, and creates the condition for the patient's prompt treatment. © 2010 IEEE. Source

Pulse carries much information about health condition of human body. Pulse diagnosis is taken as a new method known as green with no wound diagnosis and gets much attention and interest. Traditional TCM obtains pulse information depended on fingers, which has characters of simplicity, no wound and no pain and is easy for patients to accept, also presents some flaws in the long time medical practice. In order to prevent subjective assumption affecting the standard of pulse decision, meanwhile record and memorize the apperceptive pulse, a novel project about embedded pulse monitoring instrument is proposed here to study the pulse qualitatively and quantitatively. It ensures the precision of measurement and gives a new way to the research of pulse mechanism for the application and development of TCM pulse diagnosis. © 2010 IEEE. Source

Chrome-tanned collagen fiber is the major solid waste of leather industry which is difficult to biological degradation and would caused serious pollution to the environment. However, the collagen fibers as a natural biological polymer materials, has unique properties of surface reactivity that the other polymer materials are not available. In this paper, the composite film of chrome-tanned collagen fiber- polyurethane (PU) were prepared is owing to H2O induced phase separation, and measured water vapor permeability, permeability, mechanical properties and microstructure. The results showed that the composite film of chrome-tanned collagen fiber-PU have continuous porous structure, which can improve the water vapor permeability and permeability of film, but reduce the mechanical properties of film. Thermal gravimetric analysis (TGA) showed that the thermal effect of collagen fiber and PU did not change significantly, so composite of collagen fiber and polyurethane by H2O induced phase separation belongs to physical process. The result demonstrates that this composite film has continuous porous structure, and collagen fibers with unique properties of surface reactions, so this material have potential applications in many fields. © (2011) Trans Tech Publications.

Nano-SiO2/silicone modified polyacrylate emulsifier-free emulsion was synthesized by emulsifier-free emulsion polymerization and sol-gel technique. The effect of the content of nano-SiO2 on emulsion stability, solvent resistance and optical properties of film was investigated. The microstructure of the emulsion and film was studied by TEM and SEM. The results indicated that the emulsifier-free emulsion had better polymerization stability, and centrifugal stability of emulsion decreased with the increasing content of nano-SiO2. The water resistance of nano-SiO2/silicone modified polyacrylate hybrid film was better than that of silicone modified polyacrylate film, and increased with increasing content of nano-SiO2. The hybrid film had good light transmittance and ultraviolet light absorption property. In the hybrid film, silica domains smaller than 100nm were dispersed homogeneously in the polyacrylate component. Source

Corn straw fiber/poly butylene succinate (PBS) composites were prepared by hot-pressing technology. And in the same alkali environment, studied the influence of the boiled, microwave and ultrasound treatment processes on the fiber extraction rate and composites performance. The results show that three processes have activation to the fibers. By scanning electron microscope(SEM) we find that the surface of fiber treated with microwave and ultrasound is more pure, the fiber bundles were looser, mechanical properties of the fiber/PBS composites are optimal. And by energy dispersive X-ray spectroscopy (EDS) we analyze the element content of the fibers, find that the oxygen content of the fibers surface which are treated by microwave and ultrasound is higher, this result would be good to form the hydrogen bonds between the surface of straw fibers and PBS and improve the interfacial strength of composites.
