  • Patent number: 10332107
    Abstract: Systems and methods of centralized, global secure shell (SSH) key administration and management are provided, where a secure file transfer protocol (SFTP) application programming interface (API) can be leveraged to integrate centralized SSH key administration across any and all SFTP API or other file transfer installations. This allows an administrative entity to use a central server, for example, to perform client and server SSH key administration and management (e.g., SSH key creation, removal, distribution, and expiration reporting/tracking), scheduling, configuration updates, and the like across an unlimited number of file transfer installations and platforms (and therefore, is also scalable). A single management interface can be utilized for viewing and updating SSH keys for applications, and SSH keys can be propagated to application servers where the SSH keys can be activated based on a scheduled time.

  • Patent number: 9993663
    Abstract: There is presented a method 100 and apparatus 200 to measure the surface of the patient (thorax and abdominal regions), e.g., during therapy delivery and (if necessary) while imaging. Together with biomechanical considerations the position of internal structures of the patient, such as an organ, and optionally a tumor in an organ, is inferred from the measured patient surface. In case the patient breaths and thus the organ and/or tumor moves, the position may be determined, which may be advantageous during, e.g., radiation therapy, since it enables that whenever the tumor is at the right position according to the radiation therapy plan, the radiation is switched on. In a specific embodiment, a finite element model is employed.
