  • Patent number: 8050214
    Abstract: Disclosed herein is a function for controlling sound output during power on. Upon the start of its booting-up process, a mobile communication terminal determines whether a key for entering the silent mode is pressed by the user. If the corresponding key is pressed, the mobile communication terminal changes a sector of a profile in which sound information is stored, so as to boot-up in the silent mode. Because the mobile communication terminal can change the current profile during the booting-up, the user can prevent the power-on sound from being generated during power on.

  • Publication number: 20110153107
    Abstract: Disclosed are an apparatus and a method for smart energy management by controlling power consumption. Power consumption information is collected from one or more electrical device groups with a smart meter and electrical devices connected through gateways. When the method estimates that the power consumption will be larger than a threshold value, a control command is outputted to a load controller connected through the gateway and power consumption of electrical devices that belong to the electrical device using group is remotely controlled. According to an embodiment of the present invention, an energy company that produces and supplies energy can supply energy depending on a consumer's demand by using current facilities because the present invention can collect remotely energy consumption, analyze energy consumption patterns, and control automatically the energy consumption of electrical devices installed in a customer's area.
