  • Publication number: 20240145859
    Abstract: 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.

  • Publication number: 20230409713
    Abstract: 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.

  • Patent number: 7753711
    Abstract: A telecommunications plug comprising: a plug body; plug latches mounted on the plug body, the plug latches being movable between a latched and unlatched state; a boot cap having arms extending therefrom, each arm including a camming surface engaging an outside surface of the plug latches, wherein moving the boot cap in a first direction drives the latches towards each other; a cap latch mounted to the boot cap, the cap latch having a distal end positioned between the latches preventing movement of the boot cap in the first direction; the boot cap including an opening for receiving a key to deflect the cap latch allowing movement of the boot cap in the first direction.
