Abstract:
PURPOSE: A power consumption control apparatus and method are provided to conduct optimum charging and discharging control in order to improve electricity efficiency. CONSTITUTION: A power consumption control and method comprises a step of calculating a discharging cost(406) and a charging cost; and a step of comparing the charging cost and discharging cost with each other. When the discharging cost is lower than the charging cost, a power conversion part is controlled to conduct a discharging mode. When the charging cost is same as or less than the discharging cost, the power conversion part is controlled to charge a power storage part by one electricity of new renewable electricity and grid electricity.

Abstract:
PURPOSE: A power management apparatus and a controlling method thereof are provided to improve the load recognition ratio by classifying a plurality of load electric signals among total electric signals measured in a power management area after obtaining a reference electric signal of each load in advance. CONSTITUTION: A power management apparatus(100) comprises an information collecting unit(110), a measuring unit(120), a control unit(130), a storage unit(140), and an output unit(150). The measuring unit measures electric signals of at least one load prepared within the power management domain and transmits the signals to the information collecting unit and the control unit. The information collecting unit collects reference electric signals and product information corresponding to each oad. The control unit obtains unique information in the transmitted electric signal, searches for an electric signal corresponding to the measured electric signal among at least one reference electric signal, confirms the product information of the searched electric signal, and controls to indicate the confirmed product information. The storage unit stores reference electric signals and the product information of a plurality of load.

Abstract:
PURPOSE: A storage device, a storage system, and a virtualization method of the storage device are provided to promote the performance of the storage device in a virtualization environment by supporting a virtual trim command which deletes the corresponding block of a real memory corresponding to the data of the virtualized storage unit. CONSTITUTION: A storage medium(850) includes non-volatile memory. A processor(810) controls the non-volatile memory. The controller provides a virtualized storage unit for an external host through one or more non-volatile memories. The controller deletes a block of the non-volatile memory including a physical address corresponding to the data of the virtualized storage unit in response to a deletion event for the data of the virtualized storage unit.
Abstract:
PURPOSE: A method and an apparatus for booting a computer system are provided to reduce booting time in order to perform warm booting through a booting file in a DRAM. CONSTITUTION: A non-volatile memory(44) includes capturing partition for storing files which are accessed by a CPU in a capturing mode. An SSD controller(42) copies the file in a volatile memory. After copy is completed, the controller changes a data access path in a data storing device in order for the CPU to access the volatile memory.
Abstract:
PURPOSE: An apparatus and method for reproducing stereophony are provided to localize a virtual sound source at a preset height by amplifying one or more channel signals passing through an HRTF(Head Related Transfer Filter) with a gain of a speaker. CONSTITUTION: A sound signal passes through an HRTF corresponding to a preset height(S810). One or more copied sound signals are generated by copying the filtered sound signals(S820). One or more copied sound signals are amplified according to a gain corresponding to a speaker(S830). One or more amplified sound signals are outputted through the speaker(S840). A virtual sound source is located at a preset height by using a speaker arranged on a horizontal surface.
