Abstract: An operation method of a flash memory system includes reading data stored in a memory device, wherein the data is encoded by units of message blocks each including a row constituent code and a column constituent code by using a block-wise concatenated Bose-Chadhuri-Hocquenghem (BC-BCH) method; performing a hard decision decoding on the read data; determining, when the hard decision decoding fails, a reference voltage for a message block having an error among the message blocks of the read data; and performing a soft decision decoding by using the determined reference voltage.

Abstract: Disclosed is a wind turbine with a generator, which minimizes design limitations on the diameters of generators and allows a rotor and the generator to be stably fixed to a tower. The wind turbine includes a rotor including a hub at a center thereof, a rotating shaft protruding rearward of the hub, and a plurality of rotor blades provided around the hub; a generator including a housing disposed at an outer upper portion of a tower behind the rotor and provided at an inner surface of a cylindrical body thereof with a stator and a rotator rotatably coupled in the housing to rotate together with the rotor; and a support bracket fixed to an upper end portion of the tower, wherein the housing is fixed to a front surface of the support bracket to integrally fix the rotor and the generator to the tower.

Abstract: A method is for operating a data storage device including a plurality of memory chips. The method includes generating state information regarding the plurality of memory chips, storing the generated state information in a memory, receiving an access command from a host, analyzing the state information in response to the access command, and transmitting a response to the host indicative of whether the access command is performed based on the analyzed state information.

Abstract: Disclosed is a paper clamping apparatus for an office machine adapted to clamp a paper bundle outputted from the office machine while the paper bundle is being moved. A movable body adapted to move along a shaft by means of belt driving is included; a shaft holder connected to an end of the shaft at an end of the movable body and adapted to move along the shaft by means of a movement of the movable body; a base connected to the shaft at the other end of the movable body and adapted to move along the shaft by means of a movement of the movable body; and a clamp member adapted to operate so that, when the movable body moves, the paper bundle is clamped or released by means of link driving.

Abstract: Disclosed is an image forming apparatus includes an imaging forming unit configured to form an image; a main controller configured to control an operation of the imaging forming unit; a USB interface configured to receive and to transmit USB data from and to a host apparatus; a power supply configured to supply power to the image forming unit and the main controller; a switch configured to supply power selectively under the control of the main controller; and a sub controller configured to output a power control signal for turning on the switch if USB data is received from the host apparatus in a sleep mode during which the main controller is turned off. Power consumption is thereby reduced by turning off the power to the main controller in the sleep mode.
