  • ASSEMBLY AND SYSTEM INCLUDING A BIOLOGICAL SAMPLE TREATMENT CHAMBER
    Publication number: 20220042885
    Abstract: The present disclosure is directed to specimen processing assemblies including (a) a lower plate (10), (b) an upper plate (30) complementary to the lower plate, and (c) a chamber formed therefrom. In some embodiments, the formed chamber is adapted to perform an unmasking operation, e.g. antigen retrieval and/or target retrieval. In some embodiments, the specimen processing assemblies are configured to maintain a specimen-bearing substrate (15) horizontal during all processing steps. The present disclosure is also directed to systems including one or more independently operable specimen processing assemblies.

  • HEMATOXYLIN STAINER SYSTEM
    Publication number: 20210223146
    Abstract: Methods and compositions for removing precipitates or reducing the formation of precipitates generated in hematoxylin solutions. The methods and compositions feature cleaning solutions that feature chemical compounds that initiate processes including but not limited to acidification of the waste solution, chelation of metal ions in the waste solution, reduction reactions, oxidation reactions, and metal salt addition reactions.

  • Jet engine control and protection system and method
    Patent number: 6922625
    Abstract: A highly reliable, multi-channel control, monitoring, and protection system includes at least three processors in each of the redundant channels, a main processor, and first and second monitor processors. The main processor performs the main control functions, and the monitor processors mirror one or more of the functions performed by the main processor. The processing performed in the main processor and the monitor processors is continuously compared to determine whether control needs to be shifted to one of the other redundant channels.
