  • Patent number: 11986346
    Abstract: A gel pad for facilitating ultrasound scanning between an ultrasound transducer and a skin surface is provided. The gel pad has a first surface being bendable with a small degree and maintained locally flat, and a second surface being more bendable than the first surface for contacting the skin surface. A coupling media is arranged between the first and second surface with a stiffness gradient increasing from the second surface to the first surface. The first surface is capable of facilitating the ultrasound transducer to move swiftly on the gel pad. The second surface is capable of conforming to a non-uniform shape of the skin surface. On the first or second surface, position markers are provided for determining coordinates of the ultrasound transducer, by blocking ultrasound signals from transmitting through the gel pad to generate dark strips or marks in the ultrasound images.

  • Patent number: 11988799
    Abstract: A method and computing system is disclosed herein. The computing system receives, from a remote computing device, a set of production information for a plurality of plays from a region. The set of production information is directed to past production of the well. The computing system generates an input data set based on the set of production information. The input data set is generated by imputing missing production data to the production information and collapsing the data set into calendar days. The computing system fits one or more decline curves to the input data set. The computing system consolidates the one or more curves into a new data set. The computing system classifies the one or more curves by identifying a subset of wells in the new data set. The subset of wells includes a threshold amount of production information. The computing system delivers the classified results to the remote computing device.

  • Patent number: 11984195
    Abstract: The contributions of different tissues to a DNA mixture are determined using methylation levels at particular genomic sites. Tissue-specific methylation levels of M tissue types can be used to deconvolve mixture methylation levels measured in the DNA mixture, to determine fraction contributions of each of the M tissue types. Various types of genomic sites can be chosen to have particular properties across tissue types and across individuals, so as to provide increased accuracy in determining contributions of the various tissue types. The fractional contributions can be used to detect abnormal contributions of a particular tissue, indicating a disease state for the tissue. A differential in fractional contributions for different sizes of DNA fragments can also be used to identify a diseased state of a particular tissue. A sequence imbalance for a particular chromosomal region can be detected in a particular tissue, e.g., identifying a location of a tumor.
