  • Publication number: 20240134485
    Abstract: Touch screens with ultra-thin stack-ups can provide for a lower profile device, can improve the optical image on the display by reducing the display to cover glass distance, and can reduce the weight of the device. In some examples, the thickness of the touch screen stack-up can be reduced and/or the border region reduced, by removing the flex circuit connection from the stack-up. A flexible substrate can be used to enable routing of touch electrodes to touch circuitry. In some examples including a shield layer, the thickness of the touch screen stack-up can be reduced by routing the shield layer to a shield electrode on the touch sensor panel. The shield layer can then be routed to touch sensing circuitry via the flexible substrate. In some examples, the touch sensor panel or a portion of thereof can be integrated with the polarizer.

  • Patent number: 11939603
    Abstract: A modified cutinase is disclosed. The cutinase has the modified amino acid sequence of SEQ ID NO: 2, wherein the modification is a substitution of asparagine at position 181 with alanine, or substitutions of asparagine at position 181 with alanine and phenylalanine at position 235 with leucine. The modified enzyme has improved PET-hydrolytic activity, and thus, the high-activity PET hydrolase is obtained, and the industrial application value of the PET hydrolase is enhanced.

  • Patent number: 11142798
    Abstract: Disclosed are for monitoring tumor load in a patient by selecting a predetermined number of biomarker genes from DNA extracted from a tumor tissue sample from the patient to form a panel of biomarker genes (“customized genes”); isolating circulating cell-free DNA from a bodily fluid (body fluid) sample of the patient; enriching DNA sequences containing the biomarker genes in the cell-free DNA fragments; sequencing the enriched DNA; counting the number of mutated DNA and normal DNA sequencing reads in enriched DNA; and obtaining a tumor load of the patient. Optionally, the detection of mutations in genes related to therapeutic treatments (“medicine genes”) are carried out simultaneously with the testing of customized genes.

  • Publication number: 20140017257
    Abstract: A method for large-scale production of anti-NoV antibodies for use as a potential treatment for NoV disease using passive immunization. NoV-specific immunoglobulins (IgY) can be produced by immunizing chickens with NoV P particles. The birds continuously produced high titers of antibodies in their eggs for at least 3 months, in which NoV-specific antibody levels reached 4.7-9.2 mg/egg yolk. The egg yolk antibodies strongly reacted with NoV P particles by both ELISA and Western blot and blocked NoV virus-like particle (VLP) and P particle binding to the histo-blood group antigen (HBGA) receptors with a BT50 of about 1:800. The chicken IgY remain stable at 70° C. for 30 min or treatment at pH 4 to 9 for 3 hr, demonstrating that chicken IgY provides large-scale production of anti-NoV antibodies for use in passive immunization against NoV infection.

  • Publication number: 20120039666
    Abstract: An assembly to mount a catch having a number of claws to an object includes a fixing member extending through the catch to mount the catch to the object, and a limiting member mounted to the fixing member. The limiting member includes a head and a post mounted to the fixing member. The diameter of the head is greater than the distance between every two opposite claws. The head is above the claws, the fixing member, and the post are surrounded by the claws.
