Phase-rectified signal averaging (PRSA) has been known to be a useful method to detect periodicities in non-stationary biological signals. Determination of quasi-periodicities in electroencephalogram (EEG) is a candidate for quantifying the changes in the depth of anesthesia (DOA). In this paper, DOA monitoring capacity of periodicities detected using PRSA was quantified by assessing EEG signals collected...
An electrocardiosignal acquisition and processing system based on standard 12-lead system is proposed, which is small, portable, real-time and able to barrage jamming. On the basis of completing the overall design of the system, every subsystem module of hardware was being detailed designed, including electrocardiosignal preprocessing module, AD convert module, electrocardiosignal control and store...
To meet the needs of risk assessment of power transformer in power system, a condition assessment model of power transformer based on fuzzy evaluation method and information fusion technology is proposed in this paper. Typical parameters from preventative test and on-line monitoring are selected to evaluate operational condition of power transformer. The selected condition parameters are normalized...
Faults in mechanical equipment could cause breakdown of time-critical production systems, which is very expensive in terms of production losses and re-commissioning costs. In cloud manufacturing, the scattered distribution of mechanical equipment and fault diagnosis resources, such as experts and specialist instruments, etc., could hinder the development of fault diagnosis systems. The idea of resource...
Tire pressure monitoring system can monitor the real-time tire pressure of vehicles, and give an alarm when tire is at exceptional state to ensure the safety of driving, which is the life safeguard pre-warning system for drivers and passengers. A tire pressure monitoring system based on wireless sensor networks technology which is described in this paper and the hardware structure is also be put forward...
This paper investigated the development history of fault diagnostic technology for equipments, especially remote fault diagnostic system based on Internet and Web technology in detail. Then, this paper proposed a framework of remote fault diagnostic system based on emerging Grid technology to enable coordinated resource sharing and problem solving among multiple equipment suppliers and equipment users,...
