  • BIOS backup/recovery system
    Patent number: 12135611
    Abstract: A BIOS backup/recovery system includes a chassis housing a BIOS backup/recovery subsystem coupled to a primary and a secondary BIOS storage system. The BIOS backup/recovery subsystem begins initialization operations and determines whether the primary BIOS storage system includes customized MAC addresses. If so, the BIOS backup/recovery subsystem determines whether MAC addresses in the secondary BIOS storage system match the customized MAC addresses in the primary BIOS storage system and, if not, performs a BIOS backup operation that includes copying the customized MAC addresses in the primary BIOS storage system to the secondary BIOS storage system. If not, the BIOS backup/recovery subsystem determines whether MAC addresses in the secondary BIOS storage system match default MAC addresses in the primary BIOS storage system and, if not, performs a BIOS recovery operation that includes copying customized MAC addresses in the secondary BIOS storage system to the primary BIOS storage system.

  • In vitro immune synapse system and method of in vitro evaluating immune response using the same
    Patent number: 11834647
    Abstract: The present invention relates to an in vitro immune synapse system and a method of in vitro evaluating immune response using the same. The in vitro immune synapse system includes antigen-presenting cells (APCs) and at least one cell type of several specific T cell subtypes isolated from peripheral blood mononuclear cells (PBMCs), all of which is from a same individual of pigs. When a test sample is co-cultured in the in vitro immune synapse system for a given period, it can be determined that the test sample is immunogenic, immunostimulatory or not according to the immunization-related changes of these cells, thereby potentially replacing some kinds of animal experimentation.
