This paper designed a motor winding testing system, it can do the dielectric withstand voltage test of inter-turn under 30kV.The system can communicate effectively between PC and machine, by using the PC's powerful capacity of process data and PLC's better stability and the Labview's convenient UI. So the system has real-time data collection, preservation, analysis and other characteristics. This system is able to achieve factory testing and type testing of the motor windings facilitating. Various performance indicators were stable and reliable by field test during a long time.

[Purpose] AHA/ACC guidelines recommend routine use of 12-lead ECG and advance notification for patients with acute coronary syndrome. However, transmission of out-of-hospital 12-lead ECG to emergency department is still not spread and ECG interpretation on the prehospital and emergency department is not established. Therefore, we have developed and tested the clinical usefulness of the mobile telemedicine system to transmit 12-lead ECG between moving ambulances and physicians in cardiovascular emergency. [Method] We set up the mobile telemedicine using the third-generation digital mobile phone to promote communications between an ambulance and diverse hospital. Compatibility issue among device vendors was solved by the implementation of open-standard medical waveform encoding rule with motion noise-reduction system. Real time 12-lead ECG was transferred together with vital signs and live video during transfer the patient by an ambulance. The performance of the mobile telemedicine system in the field-test was checked to transfer 12-lead ECG in different scenarios such as transferred ECG from a volunteer moving hand or leg, coughing or twisting body in an ambulance driving on common road or highway. In the next step, we set up the mobile telemedicine on an ambulance to promote communications between moving 5 ambulances in Suita-city and National Cardiovascular Center since 2008 June 2. To establish the efficacy of real-time transmission of out-of-hospital 12-lead ECG, the time-line from the onset of acute myocardial infarction to reperfusion is analyzed. [Results] Totally 36 patters of 12-lead ECG were checked in the field test and all of them were comparable than those original one in the ambulance. Time-delay for transmission of 12 lead ECG was within 10seconds and for one-lead ECG monitoring and vital signs including BP, HR and oxygen saturation was 1 second without the difficulties for the interpretation. [Conclusion] Those results indicate the usefulness and reliability of transmission of 12-lead ECG using the mobile telemedicine system from the ambulance. Further investigation is on-going to determine the efficacy in clinical conditions to reduce the treatment delay for acute myocardial infarction.

Data Source

Monitoring traffic states from the road is arousing increasing concern from traffic management authorities. To complete the picture of real-time traffic states, novel data sources have been introduced and studied in the transportation community for decades. This paper explores a supplementary and novel data source, Wi-Fi signal data, to extract traffic information through a well-designed system. An IoT (Internet of Things)-based Wi-Fi signal detector consisting of a solar power module, high capacity module, and IoT functioning module was constructed to collect Wi-Fi signal data. On this basis, a filtration and mining algorithm was developed to extract traffic state information (i.e., travel time, traffic volume, and speed). In addition, to evaluate the performance of the proposed system, a practical field test was conducted through the use of the system to monitor traffic states of a major corridor in China. The comparison results with loop data indicated that traffic speed obtained from the system was consistent with that collected from loop detectors. The mean absolute percentage error reached 3.55% in the best case. Furthermore, the preliminary analysis proved the existence of the highly correlated relationship between volumes obtained from the system and from loop detectors. The evaluation confirmed the feasibility of applying Wi-Fi signal data to acquisition of traffic information, indicating that Wi-Fi signal data could be used as a supplementary data source for monitoring real-time traffic states.
