Patent number: 11979521Abstract: Data stream based event sequence anomaly detection for mobility customer fraud analysis is presented herein. A system obtains a sequence of events comprising respective modalities of communication that correspond to a subscriber identity associated with a communication service—the sequence of events having occurred within a defined period. Based on defined classifiers representing respective fraudulent sequences of events, the system determines, via a group of machine learning models corresponding to respective machine learning processes, whether the sequence of events satisfies a defined condition with respect to likelihood of representing a fraudulent sequence of events of the respective fraudulent sequences of events. In response to the sequence of events being determined to satisfy the defined condition, the system sends, via a user interface of the system, a notification indicating that the sequence of events has been determined to represent the fraudulent sequence of events.Type: GrantFiled: May 14, 2021Date of Patent: May 7, 2024Assignee: AT&T Intellectual Property I, L.P.Inventors: Ryan Steckel, Ana Armenta, Prince Paulraj, Chih Chien Huang

Publication number: 20240012438Abstract: An electronic system using a power regulator with reduced inrush current is shown. An output capacitance device that is coupled between the power regulator and the load has a first capacitor and a second capacitor. When the power regulator is in the first power mode, the first capacitor and the second capacitor are both coupled to the power regulator. When the power regulator is in the second power mode, which uses less power than the first power mode, the first capacitor is still coupled to the power regulator, but the second capacitor is disconnected from the power regulator and is protected from being discharged by the power regulator.Type: ApplicationFiled: May 19, 2023Publication date: January 11, 2024Inventors: Chih-Chien HUANG, Ming-Chiang TING
