  • Patent number: 11994343
    Abstract: Provided is a multi-part lyophilization container for lyophilizing a fluid, storing the lyophilizate, reconstituting the lyophilizate, and infusing the reconstituted lyophilizate into a patient, including a method of using same. The container includes a front surface, a back surface, a non-breathable section including a port region, a breathable section including a breathable membrane, and a peelable region including a peelable seal encompassing a boundary between the non-breathable section and the breathable section. The method includes inputting a fluid into a non-breathable section of the container, freezing the fluid, applying, in a lyophilization chamber, vacuum pressure, opening the peelable seal using a pressure differential, applying heat energy, sublimating the fluid and creating a temporary occlusion in a peelable region of the container.

  • Patent number: 7853364
    Abstract: An ion source, often used for materials processing applications in a vacuum processing chamber, is provided with an adaptive control system. The adaptive control system has a microprocessor and memory that regulate the inputs of power and gas flow into the ion source. The adaptive control system monitors and stores the dynamic input impedance properties and status of input devices to the ion source. The adaptive control system may additionally control magnetic fields within the ion source. The adaptive control system provides a multivariable control for driving any combination of input power, gas flow, magnetic field, or electrostatic ion beam extraction or acceleration field into the ion source.
