Abstract: A scanning unit includes a casing, a polygon mirror assembly disposed in the casing, and a foam metallic material disposed in the casing to absorb a noise generated by the polygon mirror assembly. Thus, the scanning unit and an image forming device having the same can absorb and remove a noise generated by the polygon mirror assembly, thereby decreasing generation of the noise and a vibration thereof and enhancing a heat release from the laser scanning unit. Additionally, the image forming device may be made more compact, since a heat radiating fin is not necessary.

Abstract: Disclosed is a method of compensating a dead time of a motor driving device comprising a current command generating unit generating a current command according to a predetermined algorithm, and a current controller generating a voltage command based on the current command, comprising the steps of measuring the voltage command while changing the current command; estimating a stator resistance value of the motor from the measured voltage command value; and compensating the dead time based on the estimated stator resistance value (R). Through these steps, since the effect due to the non-linearity of the switching devices is correctly compensated, the motor can be controlled more correctly with a low-speed.

Abstract: The resistance values of a stator and a rotor of an induction motor are estimated through the steps of (a) checking whether a control system of the induction motor reaches a normal state, (b) measuring normal state values of the values necessary for estimating resistance values of a stator and a rotor when the control system reaches a normal state, (c) estimating a stator resistance value based on the measured normal state values, (d) applying an AC component to a magnetic flux command input to the control system and calculating a first variable for estimating rotor resistance, (e) obtaining an AC component with respect to each variable by allowing the calculated first variable to pass through a band pass filter, (f) calculating a second variable for estimating rotor resistance based on the AC component with respect to the respective variables obtained above, and (g) estimating rotor resistance using the calculated second variable. Thus, since a stator resistance is estimated based on the condition of the generated torque at the time of estimating resistance of the induction motor and the rotor resistance is estimated through the AC component included in the current and voltage of the stator, the resistance values of the stator and the rotor which vary during the operation of the induction motor can be accurately estimated.

Abstract: A method for padding an input video signal having a multiplicity of image blocks for shape adaptive discrete cosine transform first scans an image block containing object and background pixels to thereby detect a padding pixel located between object pixels on a same row or column in the image block and calculates a substitute pixel value based on pixel values of the object pixels in the image block. Once the substitute pixel value is determined, the padding pixel is compensated by the substitute pixel value to thereby provide a padded image block. The padded image block having an object region containing the object pixels and the padding pixel compensated by the substitute pixel value is transformed to a set of SA-DCT coefficients through the use of the shape adaptive discrete cosine transform.
