| 20090083514 | APPARATUS AND METHOD FOR BLOCK INTERLEAVING IN MOBILE COMMUNICATION SYSTEM - A method and apparatus for block interleaving that eliminates the step of intermediary buffering. The method includes: (a) calculating a memory address at which first output data, of which number is equal to the number of rows of a first encoder is stored, (b) storing the first output data at the calculated memory address of a circular buffer, (c) storing second output data at an address which is incremented by a specific constant value from the calculated memory address of the circular buffer, and (d) storing (n+1) | 03-26-2009 |
| 20090154442 | METHOD AND APPARATUS FOR REDUCING DIGITAL TO ANALOG CONVERSION (DAC) BITS IN FREQUENCY DIVISION MULTIPLE ACCESS (FDMA) SYSTEM - A method and an apparatus for reducing Digital-to-Analog Conversion (DAC) bits at a transmitter of a Frequency Division Multiple Access (FDMA) system reduces a number of the bits for conversion so as to save power and reduce the cost of operation. The method can include generating a digital signal gain control value and an analog signal gain control value using subcarrier allocation information, a required Signal to Noise Ratio (SNR), and a Peak to Average Power Ratio (PAPR); controlling a gain of a signal input to a digital-to-analog converter using the digital signal gain control value; converting a digital signal of the controlled gain to an analog signal using the digital-to-analog converter; and restoring an original signal by controlling a gain of a signal output from the digital-to-analog converter using the analog signal gain control value. | 06-18-2009 |
| 20090196383 | CORRELATION APPARATUS AND METHOD FOR FREQUENCY SYNCHRONIZATION IN BROADBAND WIRELESS ACCESS COMMUNICATION SYSTEM - A correlation apparatus and method for frequency synchronization are provided. A frequency synchronization method of a receiver in a broadband wireless access communication system includes acquiring a highest correlation value by conducting a differential correlation of a variable interval between a received signal and a reference signal and performing a frequency synchronization according to the highest correlation value. | 08-06-2009 |
| 20100302170 | METHOD FOR OPERATING INPUT MODE OF MOBILE TERMINAL COMPRISING A PLURALITY OF INPUT MEANS - A method of operating an input mode of a mobile terminal having a first input means and a second input means is provided. The method includes: displaying an input screen which is set as a first input mode; determining whether the second input means is in an activated state; and displaying a changed input screen which is set as a second input mode when the second input means is determined to be in an activated state. | 12-02-2010 |

| 20110050011 | Motor device - A motor device includes a base plate on which a motor for rotating a disk is disposed, a flexible printed circuit board disposed on the base plate and having a circuit pattern applying power to the motor, and a screw mounting portion provided with a ground pattern of the FPCB, mounted with a screw engaged to electrically connect the ground pattern to the base plate, and having a part on which solders are provided. | 03-03-2011 |
| 20110140583 | Motor - Disclosed is a motor. The motor includes a rotor case, a ring member mounted on the rotor case and including an encoder on a bottom surface thereof extending outside of the rotor case, and an encoder sensor detecting speed information of the rotor case from the encoder such that the rotor case rotates at low speeds enabling a LightScribe operation. | 06-16-2011 |
| 20110167439 | SLIP PREVENTION MEMBER FOR TURNTABLES - Disclosed herein is a slip prevention member for a turntable. A friction layer prevents a slip of a disk placed on an upper surface thereof. A hardness reinforcing layer is provided under the lower surface of the friction layer. An adhesive layer is provided under the lower surface of the hardness reinforcing layer. A releasable sheet is attached to the lower surface of the adhesive layer. The slip prevention member reduces use of environmentally toxic material and uses the hardness reinforcing layer, thus preventing occurrence of vibrations and noise which may be induced when the hardness of the slip prevention member is relatively low. | 07-07-2011 |
| 20120011522 | Motor and optical disc drive using the same - There is provided a motor and an optical disc drive using the same, more particularly, a motor having an improved coupling structure between a rotor and a stator, and an optical disc drive using the same. The motor includes: a shaft; a sleeve supporting the shaft so as to be rotatable; a stator coupled to an outer circumferential surface of the sleeve and extended outwardly in an outer diameter direction of the sleeve; and a base plate coupled to the outer circumferential surface of the sleeve under the stator and supporting the stator. | 01-12-2012 |
| 20120025647 | SPINDLE MOTOR - Disclosed herein is a spindle motor. The spindle motor includes a rotor and a stator. The rotor includes a rotating shaft and a rotor casing which is provided with a magnet. The stator rotatably supports the rotor. The stator includes an armature facing the magnet. When the rotor casing rotates at a low speed, the rotating shaft rotates in a state of being inclined at a predetermined angle with respect to the vertical direction in which the rotating shaft is upright on the stator. Therefore, because the rotating shaft rotates in the state of being inclined with respect to the stator, the rotor can uniformly rotate. If the spindle motor is used in an optical disk apparatus for forming a label surface on an optical disk, the quality of the image on the label surface of the optical disk can be enhanced. | 02-02-2012 |
