Abstract: A systems and methods for tracking a position of an electrode. The system may include: a notching controller configured to store pitch information of a unit electrode and to acquire electrode coordinate information of the electrode in a roll-to-roll state during a notching process and a cell identification (ID) of the unit electrode; a calculator configured to calculate coordinates of the cell ID from the pitch information and the cell ID; a roll map generator configured to generate a roll map based on the electrode coordinate information transmitted from the notching controller; and a mapping part configured to compare the coordinates of the roll map with the coordinates of the cell ID to derive an electrode position of the electrode during the electrode manufacturing process from which the unit electrode originates.

Abstract: An apparatus for generating a roll map of a merge-wound electrode includes a position measurement device configured to acquire coordinate value data for a longitudinal position of an electrode according to an amount of rotation of the rewinder. The apparatus includes an input device configured to input an input signal indicating a start of merge-winding or an end of merge-winding, a seam detector configured to detect a seam, a reference point detector configured to detect a plurality of reference points of the merge-wound electrode, and a roll map generator configured to generate a roll map for simulating the merge-wound electrode moving in a roll-to-roll state based on the input signal of the input device, and to display the longitudinal coordinate values of the electrode, the electrode coordinate values of the seam, and the electrode coordinate values of the plurality of reference points of the merge-wound electrode on the roll map.

Abstract: There is provided a method and apparatus for displaying a watermark on a screen. According to the present invention, when an application is executed or a document is opened by a user's manipulation, it is determined whether a watermark is displayed based on a message generated from an operating system and screen watermark display policies, and when it is determined that the watermark is displayed, the watermark is displayed on a screen. According to the present invention, when the watermark is displayed on a screen, it is possible to provide a user with notification that corresponding content is important content or confidential content. Even when the screen is captured or is imaged using a camera, the watermark is displayed in the captured image or the imaged video. Therefore, it is possible to identify that the corresponding content is important content or confidential content. As a result, it is possible to increase user awareness of security.

Abstract: A digital demodulator which removes frequency and phase errors existing in a digital signal and converting the error-removed digital signal into a base band signal. The digital demodulator uses a frequency that is twice the transmission rate as the frequency of the sampling clock signal of an analog-to-digital (A/D) converter, and demodulates a received signal in a digital processing using the A/D converter which is low-speed. Thus, all of the received signal processing becomes digitized.
