Abstract: A power converting circuit for supplying power to an inductive load, includes an inductance, a switching circuit and an energy saving circuit. The inductance is charged when the switching circuit is conductive and discharges energy to the energy saving circuit and the inductive load when the switching circuit is nonconductive. The energy saving circuit discharges energy to the inductive load when the switching circuit is conductive.

Abstract: A power conversion circuit for supplying power to an inductive load, includes a switching circuit and an energy saving circuit. The inductive load is supplied with electrical power and the energy saving circuit is charged when the switching circuit is conductive, and the inductive load is disconnected from the electrical power supply and the energy stored in the energy saving circuit is discharged to the inductive load when the switching circuit is nonconductive.

Abstract: A control circuit for a DC motor, has: a first and second input ports for connection to a DC source; a H-bridge driving circuit, having first and second switches connected in series between the input ports, and third and fourth switches connected in series between the input ports, a first output port between the first and second switches and a second output port between the third and fourth switches, and a shunt circuit and/or a blocking circuit. The motor is connected between the first and second output ports. The shunt circuit is connected between the first second output ports and has a resistance that will decrease in response to BEMF generated by the motor. The blocking circuit is connected in series with the motor between the output ports and has a resistance that increases in response to BEMF generated by the motor.

Abstract: A cloud-based data server providing a user of a terminal apparatus with a management service for one or more home appliances connected to a home gateway through a home network using a cloud storage, and a method thereof performed by the cloud-based data server are provided. By providing the home appliance management service to the user of the terminal apparatus through the cloud-based data server, metadata, associated with the home appliances, generated by the home appliances may be managed efficiently, and the user of the terminal apparatus may remotely monitor states of the home appliances or control functions or operations of the home appliances in a home network system.

Abstract: A multimedia transcoding method and a system for performing the multimedia transcoding are provided. A hadoop-based multimedia transcoding system may include a video and image data collection domain (VIDCD) to collect original encoded media data sets, and to store the collected original encoded media data sets, a hadoop distributed file system (HDFS)-based splitting and merging domain (HbSMD) to split the original encoded media data sets into first blocks, and to automatically distribute the first blocks to a plurality of data nodes of an HDFS, by using the HDFS, and a MapReduce-based transcoding domain (MbTD) to transcode second blocks distributed to the plurality of data nodes, through distributed and parallel processing, using a MapReduce framework.

Abstract: The disclosure relates to a system, and a method, for automatically selecting a personal media apparatus and managing data under a smart media cloud environment. Specifically, the system, and the method, for automatically selecting a personal media apparatus and managing data under a smart media cloud environment, provide functions of determining the degree of control of a device and the automatic conversion of media service between a smart media contents and a cloud media contents under a private network environment by automatically selecting and controlling, in accordance with a media contents, a variety of output device under UPnP and DLNA environments, and under the structure of converting a cloud media streaming data with a media renderer connected in a smart device.
