  • Publication number: 20140292259
    Abstract: An algorithm and a direct current (DC) microgrid charge/discharge system with the algorithm are provided that noticeably increases charge/discharge voltage during charging and discharging by connecting a plurality of secondary batteries in series, compared to a single battery, that increases power conversion efficiency of a DC-to-DC (DC/DC) converter for charge/discharge power control by setting an appropriate voltage of a DC microgrid to be about twice a maximum voltage of a battery group, that enables charging and discharging to be stably performed regardless of a change in the battery group by adding a linear constant current source, that increases power conversion efficiency of the DC microgrid charge/discharge system by configuring a DC energy storage system (ESS) used for both charging and discharging with a combination of a typical electrolytic condenser and a super condenser or a group of the secondary batteries, and that simplifies the DC microgrid charge/discharge system.

  • Publication number: 20120052847
    Abstract: A mobile terminal and control method to share content with a device and control the device are provide. The mobile terminal includes a communication unit to communicate with a host and the device; a search unit to receive content information and device information; an input unit to receive a content selection signal and a device selection signal; and a control unit to control the mobile terminal. The mobile terminal receives content information from a host and selects content to be outputted to a device selected from device information from the host. The mobile terminal controls the selected device using control commands transmitted to the selected device based on a control mode. If the control mode is not stored in the mobile terminal, the mobile terminal may receive the control mode from the host.
