  • Patent number: 12439567
    Abstract: Systems and methods for controlling airflow through a casing or shelf assembly are provided. An apparatus, according to one implementation, includes a mount plate configured to be attached to a side panel of a casing for housing network equipment. For example, the mount plate may include a window. The apparatus also includes one or more hinges arranged at an edge of the window of the mount plate and a baffle pivotably attached to the one or more hinges. The baffle can be arranged within a range of positions with respect to the mount plate to control an amount of airflow through the window. Within these range of positions, the baffle is configured to redirect the airflow in a front-to-back direction through the casing.

  • Publication number: 20240296223
    Abstract: Methods and systems implement computing systems configured to trigger a volatile memory scan based on execution of computer-executable instructions, and to downselect scope of a volatile memory scan. Such techniques for triggering scans are sufficiently selective to avoid volatile memory scans for each and every running process, or vast majority of running processes. Moreover, volatile memory scans are triggered responsively after the computer-executable instructions are run, so that target processes to be scanned have not yet terminated at the time of the volatile memory scan. Additionally, a variety of techniques are implemented to minimize the volatile memory scans adversely impacting computational performance of the computing system.
