  • Publication number: 20210133971
    Abstract: A method of characterizing a serum or plasma portion of a specimen in a specimen container provides a fine-grained HILN index (hemolysis, icterus, lipemia, normal) of the serum or plasma portion of the specimen, wherein the H, I, and L classes may each have five to seven sub-classes. The HILN index may also have one un-centrifuged class. Pixel data of an input image of the specimen container may be processed by a deep semantic segmentation network having, in some embodiments, more than 100 layers. A small front-end container segmentation network may be used to determine a container type and boundary, which may additionally be input to the deep semantic segmentation network. A discriminative network may be used to train the deep semantic segmentation network to generate a homogeneously structured output. Quality check modules and testing apparatus configured to carry out the method are also described, as are other aspects.

  • Patent number: 10991689
    Abstract: A method includes forming a first region including a pair of first FinFETs and a second region including a pair of second FinFETs on a substrate. Each FinFET includes a metal gate having a first spacer adjacent thereto, and each first FinFET has a gate dielectric that is thicker than a gate dielectric of each second FinFET, such that the first FinFETs can be higher voltage input/output devices. The method forms a first contact between the metal gates of the pair of first FinFETs with a second spacer thereabout, the second spacer contacting a portion of each first spacer. The second spacer thus has a portion extending parallel to the metal gates, and a portion extending perpendicular to the metal gates. A second contact is formed between the metal gates of the pair of second FinFETs, and the second contact devoid of the second spacer.

  • Patent number: 10930892
    Abstract: An organic light-emitting diode (OLED) display panel and a method of manufacturing the same are disclosed. The OLED display panel includes a phase-compensated liquid crystal layer and a linear polarizer disposed on an organic light-emitting device layer. The phase-compensated liquid crystal layer is disposed between the organic light-emitting device layer and the linear polarizer. Polarized light is generated after external light passes through a linear polarizer and the phase-compensated liquid crystal layer and is reflected to go through again the phase-compensated liquid crystal layer in a direction perpendicular to a polarization direction of the linear polarizer. By providing a liquid crystal layer to achieve compensation for phase difference, the present application can overcome a problem of visual interference and glare effects brought about by the display panel due to external light.
