  • Patent number: 12778462
    Abstract: The present disclosure relates to a continuous blood glucose monitoring device, and provides a continuous blood glucose monitoring device, which has an incision area formed by means of a guide needle, in a state in which a body-attaching unit is insertively attached to a body, so as not to encompass at least a part of a region of a sensing area formed in a sensor member, so that the incision part is not formed near the sensing area, and thus the present invention can prevent a decrease in a blood glucose monitoring value that occurs because of the incision part so as to detect an accurate blood glucose monitoring value from an initial operation stage, and adjusts an insertion depth of the guide needle through an applicator when the body-attaching unit is insertively attached to the human body, so as to adjust the separation distance between the incision part and the sensing area by means of the guide needle, thereby improving blood glucose monitoring accuracy.

  • Publication number: 20260327959
    Abstract: An electronic shower system including a valve assembly fluidly coupled to a water supply. The valve assembly directs water from the water supply to a predefined space along a path to a showerhead. Electrical probes are positioned in association with the valve assembly. A controller is in electrical communication with the electrical probes. The controller detects when water has leaked out of the predefined space in the valve assembly and has electrically interconnected the electrical probes. The controller informs a human user or service personnel of the detected leaked water.

  • Publication number: 20260305987
    Abstract: The present disclosure relates to a continuous blood glucose measurement device configured to prevent, in a state where a body attachment unit is inserted in and attached to a human body, an incision portion made by a guide needle from being formed to surround at least a part of a sensing area formed at a sensing member, whereby an incision portion is not formed around the sensing area so as to prevent the incision portion from causing a drop in a blood glucose measurement value and thus enable detection of an accurate blood glucose measurement value from the early stage of operation. Further, the guide needle has a shape not surrounding at least a part of the sensing area, so as to prevent, even without an additional device, the guide needle from forming an incision portion around the sensing area in a human body and thus enhance, by a simple structure, the accuracy of blood glucose measurement.

  • Publication number: 20260218240
    Abstract: Provided herein are compositions and methods for multiplex generation, mapping, and characterization of structural variants in a host cell genome. A shuffle cassette includes a recombination site flanked by a pair of unique barcodes, a pair of primer binding sites, and a pair of promoters. Libraries of shuffle cassettes are integrated throughout a host cell genome, and their genomic positions are mapped by transcribing flanking genomic sequences via the promoters and associating barcode pairs with specific genomic coordinates. Upon introduction of a recombinase, recombination between integrated shuffle cassettes generates structural variants including deletions, inversions, translocations, and extrachromosomal circular DNAs. Novel barcode combinations arising from recombination events are detected to identify the class and breakpoints of each structural variant at base-pair resolution without whole-genome sequencing.
