  • Patent number: 12282022
    Abstract: A rapid, ultrasensitive and inexpensive nanoplasmon-enhanced scattering (nPES) assay that directly quantifies tumor-derived EVs from as little as 1 ?{umlaut over ({acute over (?)})}, of plasma is described herein. This assay uses binding of gold nanospheres and nanorods with EV- and tumor-derived EV-specificities to produce a local plasmon effect that enhances tumor-derived EV detection sensitivity and specificity. This nPES approach is also a non-invasive method for assessing pancreatic cancer stage and treatment response that can be easily refined for clinical use, and is readily adapted for diagnosis and monitoring of other conditions with disease-specific EV proteins.

  • Patent number: 12278555
    Abstract: A controller for an AC-DC converter including a rectifier circuit that converts AC input voltage into DC output voltage uses control logic to control the rectifier circuit according to two or more operating modes. Each operating mode determines a gain of the rectifier circuit. The controller selects an operating mode from the two or more operating modes based on at least one of an AC input voltage value and a required DC output voltage value. The AC-DC converter provides a wide range of DC output voltage with power factor correction. The controller may be used with AC-DC converter topologies such as boost converter, isolated boost converter, PWM converter, LLC resonant converter, and LCC resonant converter.

  • Patent number: 12271612
    Abstract: A method for accessing blocks of a solid state drive is described. A starting position is received, where the starting position identifies a first block of a contiguous block region within a namespace of the solid state drive. The contiguous block region is to be accessed according to a single input/output operation and the namespace comprises two dimensions of logical address space with respective indices for indexing blocks within a corresponding dimension of the logical address space. A first dimensional identifier that identifies a size of the contiguous block region in a first dimension of the namespace is received. A second dimensional identifier that identifies a size of the contiguous block region in a second dimension of the namespace is received. Blocks of the contiguous block region are accessed in response to the single input/output operation according to the starting position, the first dimensional identifier, and the second dimensional identifier.
