Patent number: 12271288Abstract: A memory operation device and method for operating a memory in an electronic device. The electronic device may determine whether a memory leak occurs in one or more low-order stack trace items with a count value of n among collected stack trace items, n being a positive integer, and, based on a low-order stack trace item among the collected stack trace items being determined as causing a memory leak, proceeding to a next order of the collected stack trace items to thereby determine whether a memory leak occurs in one or more high-order stack trace items with a count value of m which is a positive integer higher than n). When m is a maximum count value among the collected stack trace items, memory debugging may be performed using a high-order stack trace item, among the one or more high-order stack trace items, causing the memory leak.Type: GrantFiled: March 27, 2023Date of Patent: April 8, 2025Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Jihun Jung, Kyeonghwan Jung, Changhyeon Chae, Jaeook Kwon, Jusun Song, Jaehoon Jeong, Youngho Choi

Publication number: 20250010210Abstract: In a video game message generation system, a first neural network may analyze a player's gameplay data in real time to determine a moment of gameplay to record. A recording module records the moment of gameplay determined with the first trained neural network. A second trained neural network determines one or more recipients for the recording of the determined moment and a third trained neural network operable drafts a message associated with the determined moment to the determined recipient(s). A user interface presents the player an opportunity send the recording of the determined moment and the one or more messages to the one or more recipients.Type: ApplicationFiled: July 7, 2023Publication date: January 9, 2025Inventors: Ruxue Peng, Aria Lin, Toshimasa Aoki, Ai Sasho, Yuanhan Chen, Jihun Choi, Fernando Ruiz Echeverria, Trang Ho, Robert Brown, Ryder McMinn

Patent number: 11750319Abstract: We disclose a novel methodology for wireless networks that optimizes the transmission probability, transmit power at an agent, and the reflection matrix of an IRS for covert RF communications. Key features include: (1) An exact closed-form expression for the expected detection error probability (DEP) at an adversary is provided considering the transmission probability at the agent; and (2) a novel method to optimize the transmission probability, transmit power at the agent and the reflection matrix of the IRS with the goal of maximizing the achievable rate at a client while ensuring a covertness constraint is developed. More specifically, the method may require only one-dimensional line search schemes, achieves near-optimal performance, and exhibits enhanced achievable data rate when compared to the conventional technique without the transmission probability optimization.Type: GrantFiled: May 19, 2022Date of Patent: September 5, 2023Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Justin S.
