  • Publication number: 20250207100
    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.

  • Publication number: 20070186539
    Abstract: A method and system for controlling an exhaust temperature for an internal combustion engine is disclosed. The method and system comprise determining a range of acceptable charge flows within the internal combustion engine to meet a desired exhaust temperature. The method and system further comprise controlling the charge flows to fall within the range. Control strategies to utilize the charge flow as a lever to control turbine outlet temperature are disclosed. These strategies utilize the inversion of the cylinder outlet temperature virtual sensor as well as a new turbine outlet temperature virtual sensor to determine the charge flow required to achieve the desired turbine outlet temperature given the current turbine inlet and outlet pressure, SOI, charge pressure, charge temperature, fueling, and engine speed.
