Abstract: The global manufacturing development faces the new challenges including waste of resources, short delivery time, labor cost increase, short of labor, etc.. As a result, the overall industry environment of plastic materials manufacturing turns to focus on automatic production that enables manufacturing industry entering into the next phase so that production efficiency, man-made errors, and labor shortage can be improved. In this study, a cloud based platform of knowledge-driven manufacturing system integrates science bases and practical experience of injection molding with remote control technology that can enhance traditional production efficiency in several aspects such as production guidance in design/tooling/molding phases, production scheduling for all working members and equipment and processing monitoring via internet. More important is that during each working stage, sufficient knowledge are provided and guiding/driving the design/manufacturing work. The new knowledge/data are

Abstract: A system designed to protect against generator under-voltage or overvoltage, through the use of an automatic hydraulic floodgate in a micro-hydro power plant, using induction generator in a stand-alone operation, was implemented in a micro-station hydroelectric power 30[kW]. The proposed system uses 24[V] batteries in a circuit and these are always kept ready using a battery charger, designed especially for the microstation operation. The time of descent and the gate rise time, are approximately one minute and a half. Tests were performed for the operation of the gate. The proposed protection system was robust, efficient, simple and reliable.
