Abstract: The proposed sleep security and energy-saving device with heart rate as the turning point of body, provides a solution for some of the problems existing in the modern family life. Such as electrical appliances may waste too much electricity, or bring safe hidden trouble. The device is originated from the medical phenomenon which is when the body is sleeping. Human heart rate will slow down to a certain extent than normal. If the heart rate has difference with the normal levels in a period of time, the device will make a judgment that disconnects the electrical appliances.

Abstract: At present, the prediction of energy saving effect of energy saving devices, which still has some difficulties to solve in numerical methods, still depends on model test. Based on CFD technology, this paper will give a numerical prediction method of energy saving effect for compensating ducts. Firstly, the wake field of one full form ship is predicted, which includes the bare hull and hull with compensating ducts. After studying the numerical prediction method of analyzing the interaction between hull and propellers, the energy saving effect of compensating ducts is predicted with the interaction of hull and propeller. The calculation results show that the method is feasible to predict the energy saving effect of compensating ducts. The efficiency of the propeller is improved remarkably when ship hull is installed the compensating ducts.

Abstract: As port cranes becoming larger, the electricity and other energy they consumed increase significantly. The research on energy saving of port cranes is increasingly hot nowadays. This paper first discusses the latest research activities on the energy saving measures of cranes. Then, taking the quayside container crane as an example, the measuring method for its energy consumption is presented and analyzed. Finally, an energy saving device for port cranes is designed to convert the motor’s no useful working energy into electricity for lighting. The design, structures and working process of this device are described in detail.
