Patent number: 11866791Abstract: 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.Type: GrantFiled: September 8, 2022Date of Patent: January 9, 2024Assignee: CellMax Ltd.Inventors: Huangpin B. Hsieh, XiaoMing Wang, Jr-Ming Lai, Rui Mei, Hung-Jen Shao, Jen-Chia Wu

Patent number: 10238995Abstract: 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.Type: GrantFiled: June 13, 2014Date of Patent: March 26, 2019Assignee: Palo Alto Research Center IncorporatedInventors: Armin R.

Patent number: 9758407Abstract: 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.Type: GrantFiled: December 20, 2013Date of Patent: September 12, 2017Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Huangpin B.
