Publication number: 20230027840Abstract: Disclosed is a method of analyzing a programmable logic controller (PLC) logic to detect whether an anomaly that deviates from a standard pattern occurs in a repeated cycle. After modeling and patterning an operation pattern of automation equipment and processes with a graph, an anomaly detecting model capable of detecting whether a pattern is abnormal may be constructed as a graph AutoEncoder model. By detecting the change in the process pattern, it is possible to early detect the anomaly of the equipment and processes.Type: ApplicationFiled: July 20, 2022Publication date: January 26, 2023Applicant: UDMTEK CO., LTD.Inventors: Gi Nam Wang, Jun Pyo Park, Seung Woo Han, Geun Ho Yu, Min Young Jung, Hee Chan Yang, Seung Jong Jin

Patent number: 7663573Abstract: The present invention relates to a plasma display panel and driving method thereof, which involves controlling the time points when data signals are applied to the data electrodes during an address period, thereby reducing the noise that otherwise affects the waveforms applied to the Y electrodes and the Z electrodes. This, in turn, stabilizes the address discharge and prevents damage to the scan board and/or the sustain board. According to one embodiment of the present invention, the data electrodes are divided into a plurality of electrode groups, where each of the electrode groups receives the data signal at an application time point that is different from the remaining electrode groups.Type: GrantFiled: June 20, 2005Date of Patent: February 16, 2010Assignee: LG Electronics Inc.Inventors: Jin Young Kim, Hee Chan Yang

Patent number: 7408530Abstract: The present invention relates to to an apparatus for driving a plasma display panel in which an image being full of life is represented through expansion of contrast and the gray level can be expanded, and method for driving the same. According to the present invention, since a gray level of an input data is distributed over the whole gray level region, contrast can be expanded. It is therefore possible to display an image being full of life. Furthermore, if the gray level of the input data is expanded over the whole gray level region, contrast is increased. Moreover, when the gray level region is expanded, an error diffusion unit and/or a dithering unit are/is not used.Type: GrantFiled: September 22, 2004Date of Patent: August 5, 2008Assignee: LG Electronics Inc.Inventor: Hee Chan Yang
