  • Patent number: 11981885
    Abstract: A cell cultivation apparatus for cultivating microorganisms and growing cells at high density is provided. The apparatus includes a membrane comprising multiple surface features on a first side of the membrane for cell placement. The surface features comprising one or more compartments within which a cell can be located. The membrane includes a material that is at least partially permeable to gas. A second side of the membrane defines a gas region. The second side of the membrane is separated from the first side of the membrane by the membrane. The apparatus further includes a media region for receiving media. The compartments are configured to at least partially reduce media flow shear forces on one or more cells in the compartments. The surface features may be ridges, protrusions, fins, wells, and/or posts.

  • Patent number: 6500680
    Abstract: Within both a system for managing a work-in-process (WIP) workload within a fabrication facility and a method for managing the work-in-process (WIP) workload within the fabrication facility, there is determined from an overall routing sequence for fabricating the work-in-process (WIP) workload within the fabrication facility a series of routing sub-sequences which correspond with a series of service codes. By using the series of service codes for routing the work-in-process (WIP) workload within the fabrication facility there may be realized operational efficiencies when fabricating the work-in-process (WIP) workload within the fabrication facility.
