Abstract: Disclosed herein is a method for compressing an image using a permissible-error (PE) encoding method and a dynamic link-size encoding method. An image compression efficiency can be increased by selectively applying the permissible-error encoding method and the dynamic link-size encoding method to a zero loss compression method, for example, a Lempel-Ziv compression method.

Abstract: A workflow data binding system facilitates binding of a data component to a feature of a software component. Prior to the binding, a graphical indication of the software component and a graphical indication of the feature of the software component are displayed. In addition, an indication of an element of the data component is displayed in a display area approximately adjacent to the displayed software component. The workflow data binding system receives a user input command to bind the data component to the feature of the software component. The user input command may include dragging the indication of an element of the data component from the data component display area to the feature of the software component and subsequently dropping it on the feature. As a result, the workflow data binding system automatically generates script or code that provides executable instructions to bind the feature of the software component to the data component.

Abstract: An automatic input-gain control circuit of an audio amplifier and a method thereof are provided. If an acoustic signal exceeds a dynamic range, a gain of the acoustic signal can be automatically attenuated based on a pre-set limit level to minimize a distortion of the acoustic signal caused by clipping of the acoustic signal and limit an over-input so as to input the acoustic signal within the dynamic range. Thus, an original form of an over-input signal on a specific level or more can be maintained but only a gain of the over-input signal can be attenuated. As a result, a distortion of an output waveform caused by clipping of the output waveform can be minimized, and a harmonic distortion and a stepped high frequency noise occurring during clipping can be simultaneously removed.
