  • Publication number: 20240303152
    Abstract: A central system coupled to a subsystem receives a fault indication associated with a fault in one or more circuits of the subsystem from a local fault collection and control (FCCS) of the subsystem when a software recovery of the fault fails. Based on the received fault indication, the local FCCS and a central FCCS of a central system is masked from additional fault indications from the one or more circuits. The central system then signals the reset of the one or more circuits of the subsystem after the masking of the additional fault indications, wherein the one or more circuits is reset based on the signaling and the additional faults are masked from one or more of the local FCCS and central FCCS during the reset.

  • Publication number: 20240102997
    Abstract: Improved biotin blocking methods are provided which utilize a high-affinity monomeric biotin-binding protein of the avidin family that have only a single biotin binding site. Because the biotin-binding protein is monovalent, it can be applied as a single reagent. Since it does not introduce any additional biotin binding sites, as would be the case with native tetrameric streptavidin, no further blocking of biotin binding sites is necessary. Furthermore, because it is a single reagent, it can be combined with other steps such as the peroxidase blocking step, and both endogenous peroxidase and endogenous biotin can be blocked simultaneously. The biotin blocking methods may be used in the performance of immunoassays, such as tissue sample containing endogenous biotin is stained by IHC to detect a specific analyte. Prior to staining, the tissue is first blocked for endogenous biotin, according to the present invention, by the application of a high-affinity biotin-binding protein.
