  • System and method for real-time volume control
    Patent number: 11016006
    Abstract: A real-time imaging method and system for monitoring an assay process performed on a biological sample is described. In some embodiments, the method and system can be used to measure and control a reagent volume confined to a space between a cover and a substrate, which is particularly useful for controlling for evaporation in a thin-film staining environment. In particular embodiments, the disclosed reagent volume sensing and replenishment method and system are resistant to system noises generated during operation, for example, system noise due to vibration, field of view blockage by dispenser systems, differences in reagent colors, and changing tissue colors.
    Type: Grant

  • Opposables and automated specimen processing systems with opposables
    Patent number: 10746752
    Abstract: A specimen processing system is capable of processing specimens carried on slides. The specimen processing system can sequentially deliver slides and opposables to specimen processing stations. The specimen processing stations can use the opposables to apply a series of liquids to the specimens. The applied liquid can be moved along the slide using capillary action while the specimen processing stations control the processing temperatures. The applied liquid can be in a fluid-carrying gap. The opposable can contact the slide to vary a cross section of the fluid-carrying gap.
