Publication number: 20240105136Abstract: An electronic device includes a display unit, a voltage generation unit, a grayscale adjustment unit, and an overdriving unit. The display unit has a relationship curve between the transmittance and the driving voltage. The relationship curve has a predetermined voltage value corresponding to the maximum transmittance. The voltage generation unit generates a first voltage according to a first grayscale, and generates a second voltage according to a second grayscale. The grayscale adjustment unit receives a first display grayscale value, and outputs the second grayscale value when the first display grayscale value is equal to the first grayscale. The overdriving unit overdrives the second voltage corresponding to the second grayscale to obtain a first target driving voltage, and it provides the first target driving voltage to the display unit.Type: ApplicationFiled: August 17, 2023Publication date: March 28, 2024Inventors: Syue-Ling FU, Yeh-Yi LAN, Cheng-Cheng PAN, Meng-Kun TSAI

Patent number: 11481687Abstract: Machine learning techniques are used in combination with graph data structures to perform automated classification of accounts. Graphs may be constructed using a seed node and then expanded outward to second-degree nodes and third-degree nodes that are connected to a seed user account node via direct interaction between the accounts. Characterization information regarding the interaction between accounts can be stored in the graph (e.g., quantity of interactions, types of interactions) as well as other metrics and metadata. A classifier, using random forest or another technique, may be trained using a number of different graphs that can then be used to reach a determination as to whether a user account falls into one particular category or another. These techniques can identify accounts that may be violating terms of service, committing a security violation, and/or performing illegal actions in a way that is not ascertainable from human analysis.Type: GrantFiled: October 30, 2021Date of Patent: October 25, 2022Assignee: PAYPAL, INC.Inventors: Chuanyun Fang, Matias Rotenberg, Adam Cohen, Chunmao Ran, Kun Fu, Itzik Levi

Patent number: 11340679Abstract: An uninterruptible power system (UPS) testing method includes the steps of setting an operational decline table, setting an initial value, collecting data, inputting targets, executing multi-algorithm, and indicating a warning or an approval. Wherein, battery cells of the UPS are repeatedly tested when being actually used at different temperatures to set the operational decline table and the initial time value; and data about temperatures and time periods of the battery in operation are continuously collected for a user to execute algorithms based on designated conditions to predict the battery state in a future time period; and an indication message is generated for the user to determine whether the battery is still usable or has to be replaced. In this manner, it is able to estimate the running time of a target time of the UPS without the need of performing an actual electrical discharge procedure.Type: GrantFiled: May 5, 2021Date of Patent: May 24, 2022Assignee: DYNAPACK INTERNATIONAL TECHNOLOGY CORPORATIONInventors: Chung-Hsing Chang, Heng-Yi Cheng, Po-Han Lee, Chien-Yueh Tung, Kun-Fu Lee, Chung-Chih Tseng

Publication number: 20220084037Abstract: Methods and systems are presented for classifying a particular user account as a fraudulent user account by analyzing links between the user account and two or more known fraudulent user accounts collectively. Attributes of the particular user account are compared against attributes of a plurality of known fraudulent accounts to determine that the particular user account has shared attributes with a first known fraudulent account and a second known fraudulent account. The shared attributes with the first known fraudulent account and the second known fraudulent account are analyzed collectively to determine a risk level for the particular user account. The risk level may indicate a likelihood that the particular user account corresponds to a fraudulent account.Type: ApplicationFiled: November 22, 2021Publication date: March 17, 2022Inventors: Chuanyun Fang, Chunmao Ran, Itzik Levi, Kun Fu, Adam Cohen, Avishay Meron, Doron Hai-Reuven, Amnon Jislin
