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.

Abstract: A mechanism for establishing a plurality of sessions between a client and a first server based on a single input of user authenticating information is disclosed. A request to establish a connection between the client and the first server is received. The request includes identification information for authenticating a requesting user. Based on the identification information, a determination is made as to whether the connection between the client and the first server should be established. If it is determined that the connection between the client and the first server should be established, the identification information is cached in memory and the connection between the client and the first server is allowed to be established. Subsequent connection requests from the same client are authenticated, and further connections can be established, based on the cached identification information, without further input from the client or user.
