  • Patent number: 12339965
    Abstract: Disclosed are systems, methods, and non-transitory computer-readable storage media for malware detection and content item recovery. For example, a content management system can receive information describing changes made to content items stored on a user device. The content management system can analyze the information to determine if the described changes are related to malicious software on the user device. When the changes are related to malicious software, the content management system can determine which content items are effected by the malicious software and/or determine when the malicious software first started making changes to the user device. The content management system can recover effected content items associated with the user device by replacing the effected versions of the content items with versions of the content items that existed immediately before the malicious software started making changes to the user device.

  • Publication number: 20240315728
    Abstract: A neonatal pneumothorax decompression device is disclosed. The device comprises a needle stabilizer, a pressure indicator, and a fluid evacuation pump. The needle stabilizer is configured to facilitate insertion of the needle into a subject's pleural cavity and to hold a needle at an adjustable length. The pressure indicator is coupled to the proximal end of the needle stabilizer and is configured to visibly display pressure within the subject's pleural cavity. The fluid evacuation pump is configured to be actuated by a user to evacuate air or fluid from the subject's pleural cavity through the needle. The fluid evacuation pump is proximally coupled to the pressure indicator and the needle stabilizer.

  • Patent number: 11188559
    Abstract: The present technology pertains to an organization directory hosted by a synchronized content management system. The corporate directory can provide access to user accounts for all members of the organization to all content items in the organization directory on the respective file systems of the members' client devices. Members can reach any content item at the same path as other members relative to the organization directory root on their respective client device. In some embodiments novel access permissions are granted to maintain path consistency.
