  • Patent number: 11866791
    Abstract: Techniques for identifying and enumerating candidate target cells within a biological fluid specimen are described. A digital image of the biological fluid specimen is received, and one or more candidate regions of pixels in the digital image are identified by identifying connected regions of pixels of a minimum intensity having a size between a minimum size and a maximum size and an aspect ratio that meets a threshold. For each candidate region of at least one of the one or more candidate region, whether the portion of the image corresponding to the candidate region includes more than a threshold number of intensity levels is determined. If the portion of the image corresponding to the candidate region includes more than the threshold number of intensity levels the portion of the image is continued to be treated as a candidate for classification.

  • Patent number: 11866792
    Abstract: A method for identifying candidate target cells within a biological fluid specimen includes a digital image of the biological fluid specimen with the digital image having a plurality of color channels, identifying first connected regions of pixels of a minimum first intensity in a first channel, identifying second connected regions of pixels of a minimum second intensity in a second channel, and determining first connected regions and second connected regions that spatially overlap. For a pair of a first connected region and a second connected region that spatially overlap, whether the second connected region overlaps the first connected region by a threshold amount is determined, and if the second connected region overlaps the first connected region by the threshold amount then the portion of the image corresponding to the overlap is continued to be treated as a candidate for classification.

  • Patent number: 10238995
    Abstract: Hydrodynamic separation of suspended particles using curved channels offers advantages in many applications, since it is a fast continuous flow technology that can handle neutrally and near neutrally buoyant particles without the need of a physical barrier or the addition of chemical aids. Designs are provided for a flow splitter at the end of the separation channel, to maintain smooth, counter-vortex-free laminar flow and improve particle separation efficiency while reducing clogging and fouling propensities.

  • Patent number: 9758407
    Abstract: A wastewater treatment plant that employs an activated sludge process and a method of operating the same is described. Wastewater influent is provided to a bioreactor configured to perform activated sludge processing to develop mixed liquor suspended solids (MLSS). The MLSS is passed from the bioreactor to a hydrodynamic separator (HDS) system, where separation operations are performed on the MLSS. The separation operations generate a low concentration MLSS stream and a high concentration MLSS stream. The low concentration MLSS stream is passed from the hydrodynamic separator system via a first output to a clarifier, and the high concentration wastewater stream is passed via a second output back to the bioreactor. The clarifier performs clarification operations on the cleaned wastewater stream and then outputs an effluent flow.

  • Patent number: 9624116
    Abstract: A mobile HEB and TEP mitigation device includes a mobile body capable of movement within or upon a body of water. Located within the mobile body is a hydrodynamic separation system which includes a water inlet, a hydrodynamic separation unit and a collection tank. The hydrodynamic separation unit includes two outputs, one for a clean stream output line containing clean water and arranged to re-circulate the clean water, and another for a concentrate stream output line, the concentrate stream output line configured to place concentrated water containing potentially harmful bio-organic materials into the collection tank. Also included on the mobile body is a power source and an engine/steering unit, wherein the steering portion of the engine/steering unit provides a capacity to move the mobile body in an intended direction. The mitigation device may also be used as an embedded part of an on-shore arrangement.
