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: A refrigerator has a shelf seating protrusion and a separate shelf seating member. The shelf seating protrusion is not formed at an approximate mid-point, height wise, of a storage space defined by an inner casing. The shelf seating member may be coupled to the inner casing to support a shelf assembly. An arrangement of the shelf seating protrusions and the shelf seating member is configured to reduce deformation and cracking of the inner casing due to thermal impact in a manufacturing process or when items are stored on the shelf assembly.

Abstract: Methods and systems for executing tracking and monitoring manufacturing data of a battery are disclosed. One method includes: receiving, by a server system, sensing data of the battery from a sensing system; generating, by the server system, mapping data based on the sensing data; generating, by the server system, identification data of the battery based on the sensing data; generating, by the server system, monitoring data of the battery based on the sensing data, the identification data, and the mapping data; and generating, by the server system, display data for displaying a simulated electrode of the battery on a graphical user interface based on the monitoring data of the battery.

Abstract: A method of inspecting a display substrate including pixel patterns provided in pixel areas disposed in a display area in a first direction and a second direction may include obtaining a captured image of the pixel patterns of the display substrate, grouping pixels included in the captured image by grouping at least two pixels disposed in the first direction into a pixel group, designating each pixel group included in the captured image as a target pixel group, comparing pixel patterns of the target pixel group with pixel patterns of an adjacent pixel group positioned in a third direction with respect to the target pixel group, and determining whether the pixel patterns of the target pixel group are defective.

Abstract: If a request to execute an executable file of a guest operating system or an executable file being executed in the guest operating system is detected, the present disclosure calculates a hash value before the executable file is executed and compares the calculated hash value with a pre-stored hash value, thereby securing security of the executable file; parses a file system of the guest operating system prior to starting the guest operating system and verifies integrity of a virtualization driver, and if the virtualization driver has integrity according to a result of the verification, blocks modulation of a memory area where the virtualization driver is allocated, a memory area corresponding to a master boot record (MBR) of the guest operating system, and a memory area corresponding to a volume boot record (VBR) of the guest operating system, and if an access to a file occurs in the virtualization driver, determines authority to access the file to which the access was requested, and processes the access acco
