Abstract:
An electronic device is provided. The electronic device includes a first connector including a first pin and a second pin configured to connect with a first external electronic device, a second connector configured to connect with a second external electronic device, a connection sensing circuit configured to sense a connection or disconnection of the second external electronic device coupled to the first pin via the second connector, and a switch configured to supply power received from the first external electronic device via the second pin to the first pin if the disconnection is sensed via the connection sensing circuit.
Abstract:
A power management apparatus includes an electric device including a plurality of operation algorithm information and power information for each operation level corresponding to each operation algorithm information, and a power management unit to receive power rate information from a power provider, determine an operation level of the electric device on the basis of the received power rate information and power information for each operation level of the electric device, and control an operation of the electric device at the determined operation level. As a result, the power management apparatus performs different operation algorithms according to power rate information, and controls power consumption of the electric device, such that energy efficiency at the user side can be maximized. In response to the changed power rate information, the currently-driven electric device and the electric device to be driven can be driven at the optimum operation level appropriate for their power consumption characteristics.
Abstract:
A method of operating a controller includes receiving write data having chunks from a host, assigning each of finger prints to each of the chunks, counting the number of duplications of each of the finger prints, and changing a physical address assigned to each of first finger prints among the finger prints based on a count value of each of the finger prints based on a count value of each of the finger prints, and the physical address is assigned by a flash translation layer (FTL).
Abstract:
A power management apparatus is provided. The apparatus includes a communication unit configured to receive information on a price of power and communicate with image forming apparatuses, and a control unit configured to control image forming apparatuses to operate at a normal mode and/or a power saving mode by comparing the information received on the price of power with information on a standard price of power. A user may conduct a printing at a desired time to minimize inconvenience. A mode of the power management apparatus is determined according to the price of power such that a plurality of image forming apparatuses are operated at a normal mode when the price of power is low, and at least one image forming apparatuses is operated at a normal mode when the price of power is high, thereby reducing cost and enhancing the efficiency in managing the power.
Abstract:
A method for controlling a power management system includes if a registration mode of a smart socket is performed in a power management apparatus, displaying a second code of the power management apparatus; acquiring a code image of the second code on the power management apparatus using a terminal acquiring a code image from a first code assigned to the smart socket to recognize each other; receiving information of an electric device to be coupled to the smart socket; and pairing the smart socket corresponding to the first code by reading the code image with the electric device information, transmitting the paired information to the power management apparatus corresponding to the second code, and storing the paired information in the power management apparatus corresponding to the displayed code.
Abstract:
An electronic device and an object control method therefor are provided. The electronic device includes a display module configured to display at least one object on a screen of the electronic device, a user input module configured to receive a user input, and a processor configured to compare a coordinate of each of the objects with a coordinate of the user input and to control attributes of each of the objects.
Abstract:
A power consumption control apparatus and a power consumption control method capable of providing a power storage being utilized as an uninterruptible power supply (UPS), and in a case of an emergency, automatically selecting a load to supply a backup power to the load, the power consumption control method including determining an occurrence of an abnormality in a supply of a grid power and a renewable power, performing an emergency mode to immediately finish a current operation of a load if it is determined that an abnormality in the supply of both of the grid power and the renewable power has occurred, and performing a standby mode to stand by until the current operation of the load is finished in a normal manner if it is determined that an abnormality in the supply of the grid power has occurred while the supply of the renewable power is normal.
Abstract:
A power consumption control apparatus and method, the power consumption control method including calculating a charging cost, which represents a cost of power in a case of charging power, and a discharging cost, which represents a cost of power in a case of discharging power, of a power storage unit where the charging and discharging of power is performed, comparing the charging cost with the discharging cost of the power storage unit, controlling a power conversion unit to perform a discharging mode of performing one of the discharging of power and a reselling of power if the discharging cost is lower than the charging cost, and controlling the power conversion unit to perform a charging mode of charging the power storage unit with at least one of a new renewable power and a grid power if the charging cost is equal to or lower than the discharging cost.
