  • Patent number: 12281331
    Abstract: Methods provided by the present disclosure utilize extracorporeal shockwaves, mechanical impacts and/or principles of lithotripsy to break up a tissue sample into smaller fragments—clusters of cells and/or single cells—after which a desired cellular fraction can be isolated from the sample. Devices provided by the present disclosure deploy focused and/or directed shockwaves, and/or focused and directed mechanical impacts, to break apart a tissue sample. The devices maintain the sample in a sterile, closed environment during exposure to the shockwaves or mechanical impacts. Therefore, the shockwaves and/or mechanical impacts are generated outside of a closed device and are transmitted through one or more walls of the device into its interior, where the sample is located.

  • Patent number: 12274023
    Abstract: Methods and systems for thermal management of hardware resources are disclosed. To improve the likelihood of the computer implemented services being provided, the systems may include information transmission topologies that are more likely to properly transmit operating point information (e.g., actual fan rates, rates at which fans are to operate, etc.) between management entities such as thermal managers and entities managed by the thermal managers such as fans (and/or other types of gas flow control components). By doing so, the system may be more likely to provide thermal management services as intended by using the transmitted information that is more likely to be accurate.
