Publication number: 20240152329Abstract: A k-cluster residue number system has a processor and memory coupled to the processor. The processor is used to generate a modular set composed of P coprime integers, generate a dynamic range by taking a product of the P coprime integers, generate quotient indices for all integers in the dynamic range, generate row indices for all integers in the dynamic range, generate column indices for all integers in the dynamic range, and generate a look-up table according to the quotient indices, row indices, the column indices, and all integers in the dynamic range. P is an integer greater than 2, and the P coprime integers include 2. The memory is used to store the look-up table.Type: ApplicationFiled: November 1, 2022Publication date: May 9, 2024Applicant: Kneron Inc.Inventors: Oscar Ming Kin Law, Chun Chen Liu

Publication number: 20240152330Abstract: A k-cluster residue number system has a processor and a memory. The processor is used to generate an addition and subtraction look-up table and a multiplication look-up table based on periodic behaviors of the modulo to compress the sizes of the addition and subtraction look-up table and the multiplication look-up table. The addition and subtraction look-up table has 2mi cells for recording values from zero to (mi?1) in an ascending order twice, wherein mi is a coprime integer of a modular set of the k-cluster residue number system. The multiplication look-up table has S cells, where S = ( m i 2 - 1 4 ) .Type: ApplicationFiled: November 2, 2022Publication date: May 9, 2024Applicant: Kneron Inc.Inventors: Oscar Ming Kin Law, Chun Chen Liu

Publication number: 20240145859Abstract: A battery system includes a cover including a plurality of guide apertures. The battery system includes a thermal barrier disposed adjacent the plurality of guide apertures of the cover. The battery system includes a stiffening structure disposed between the cover and the thermal barrier. The plurality of guide apertures guides emissions through the cover, and the thermal barrier absorbs heat energy generated by the emissions. The battery system may further include a plurality of battery cells, and the thermal barrier may be disposed between the plurality of battery cells and the cover. Each of the plurality of guide apertures of the cover may be aligned with a vent of one of the plurality of battery cells. The stiffening structure may also include cutouts each shaped to correspond to at least one vent. The stiffening structure may also include indentions to press the thermal barrier against the plurality of battery cells.Type: ApplicationFiled: November 1, 2022Publication date: May 2, 2024Inventors: Yuhang Chen, Oscar Francisco Cervantes Huacuja

Publication number: 20230409713Abstract: Described herein is a system that detects ransomware infection in filesystems. The system detects ransomware infection by using backup data of machines. The system detects ransomware infection in two stages. In the first stage, the system analyzes a filesystem's behavior. The filesystem's behavior can be obtained by loading the backup data and crawling the filesystem to create a filesystem metadata including information about file operations during a time interval. The filesystem determines a pattern of the file operations and compares the pattern to a normal patter to analyze the filesystem's behavior. If the filesystem's behavior is abnormal, the system proceeds to the second stage to analyze the content of the files to look for signs of encryption in the filesystem. The system combines the analysis of both stages to determine whether the filesystem is infected by ransomware.Type: ApplicationFiled: August 30, 2023Publication date: December 21, 2023Inventors: Oscar Chen, Di Wu, Benjamin Reisner, Matthew Edward Noe
