OBJECTIVE: To develop a self deep breathing training device which can improve lung function compliance and blood oxygen saturation. METHODS: The device consists of four parts:flow tube, measuring cylinder, mobile phone holder and meridian guidance audio-visual synthesis training software. The flow tube measures the flow rate of inhaled gas, the metering cylinder measures the total amount of inhaled gas, and the mobile phone rack is equipped with a mobile phone storing the meridian guidance audio-visual synthesis training software. RESULTS: The device is reasonable in structure and flexible in operation, which can meet the requirements of self deep inspiration training under the guidance of training module. CONCLUSIONS Deep inspiration training under the guidance of guidance training module can form "deep and slow" abdominal breathing, and then improve lung function.

OBJECTIVETo assay and study the microwave leakage of 4 types of interphones.

METHODSThe radiation intensities of four types of 199 interphones were determined by the microwave leakage measure instrument of model ML-91 made in China.

RESULTSThe average intensities of microwave leakage at a distance of 5 cm from aerial part and other parts of interphones during launching [(1 316.0 +/- 144.3), (971.0 +/- 131.6) microW/cm(2) respectively] were significantly higher than during waiting [(14.4 +/- 5.3), (13.2 +/- 4.9) microW/cm(2) respectively] (P < 0.01). The average intensities of microwave leakage at a distance of 50 cm from different parts were (357.3 +/- 27.8) microW/cm(2). The daily average intensity of microwave leakage to which the head, chest and abdomen exposed was (945.5 +/- 447.1) microW.h/cm(2) in total, that exceeded the hygienic standard of microwave in China (400 microW.h/cm(2)), during the normal communication by interphones.

CONCLUSIONThe microwave leakage was higher during launching than during waiting, and was the highest at the aerial part of the interphones. The microwave radiation of most interphones was higher than the current national standard. It may lead to potential effects on the owner of interphone, so protection against it should be made.

PURPOSEDeveloping an exercise management software based on a smart phone to intervene wearer's exercise amount.

METHODUsing the Android system of mobile phone which contains acceleration sensor to detect the wearer's exercise amount, at the same time, the sensor send the information to the health management center.

CONSEQUENCEIt can carry out behavior intervention by the health management center's information feedback indication, thus guide the wearer to take exercise scientifically and safely to reach the most effective and appropriate exercising result, which realizes the system function.

CONCLUSIONThe behavior intervention based on Smart phones can apply as a new clinical measure to treat patients.

The development of muscle strength evaluating system based on Android system was developed in this research. The system consists of a lower unit and an intelligent mobile terminal. The pressure sensor of the lower unit was used to collect muscle strength parameters. And the parameters were sent to the Android device through the wireless Bluetooth serial port. Then the Android device would send the parameters to the doctor monitored platform through the Internet. The system realized analyzing the muscle strength parameters and real-time displaying them. After it ran on the Android mobile phones, it showed an effective result which proved that the system combined with mobile platform could make more convenient for the patients to assess their own muscle strength. It also provided reliable data references for doctors to know the patients' rehabilitation condition and to make the next rehabilitation plan.

This article proposes a new device named "Wireless Cellscope" that combining mobile phone and optical microscope together. The established wireless microscope platform consists of mobile phone, network monitor, miniaturized microscope or high resolution microscope etc. A series of conceptual experiments were performed on microscopic observation of ordinary objects and mice tumor tissue slices. It was demonstrated that, the new method could acquire microscopy images via a wireless way, which is spatially independent. With small size and low cost, the device thus developed has rather wide applicability in non-disturbing investigation of cell/tissue culture and long distance observation of dangerous biological sample etc.

The technical structure of a low-cost thermal imaging system (TIM) lunched on a mobile phone was investigated, which consists of a thermal infrared module and mobile phone and application software. The designing strategies and technical factors toward realizing various TIM array performances are interpreted, including sensor cost and Noise Equivalent Temperature Difference (NETD). In the software algorithm, a mechanism for scene-change detection was implemented to optimize the efficiency of non-uniformity correction (NUC). The performance experiments and analysis indicate that the NETD of the system can be smaller than 150 mK when the integration time is larger than 16 frames. Furthermore, a practical application for human temperature monitoring during physical exercise is proposed and interpreted. The measurement results support the feasibility and facility of the system in the medical application.
