  • Patent number: 11119234
    Abstract: A method for generating a geophysical image of a subsurface region includes defining a computational sub-volume for the geophysical image including a predetermined number of seismic traces of a plurality of seismic traces and a predetermined number of samples per each one of the plurality of seismic traces, generating a data matrix corresponding to a first sub-volume of the subsurface region based on the defined computational sub-volume, the data matrix comprising the predetermined number of samples for the predetermined number of traces of a portion of a seismic dataset corresponding to the first sub-volume. The method also includes performing a singular value decomposition and estimating a coherence between the predetermined number of traces of the data matrix by performing a weighted sum of a variance of a plurality of right singular vectors of the data matrix, and assigning the estimated coherence to a location in the geophysical image.

  • Patent number: 11016212
    Abstract: A three-dimensional (3D) seismic data set is divided into a plurality of 3D source wavefield subsets, each 3D source wavefield subset is stored in an array element of an array. For each array element, the associated 3D source wavefield is decomposed into a smaller data unit; data boundaries of the smaller data units are randomly shifted; a folding operation and a sample operator is applied to the smaller data units to keep the smaller data units from overlapping; the folded smaller data units are smoothed to generate smoothed data; a quantization operation is performed on the smoothed data to produce quantized data; and the quantized data is compression encoded to generate compressed data. The compressed data associated with each array element is decompressed to generate a 3D seismic output image.

  • Patent number: 10764715
    Abstract: Described is a technology by which a mobile computing device such as a mobile telephone operates differently based on detected proximity to another mobile device with which the first mobile device has a defined relationship. For example, the first mobile device may transfer content to the second mobile computing device when proximity corresponds to a non-cellular communications coupling, such as Bluetooth® or Wi-Fi coupling. In this manner, content transfer is deferred until a non-cellular coupling exists. The mobile device (or both devices) may output a notification to indicate that the other mobile computing device has been detected within a threshold proximity, such as via GPS data or by being within the same cellular tower. The type and/or settings of an output notification may vary based on different thresholds.

  • Patent number: 10672940
    Abstract: The present invention discloses a high-resistivity single crystal zinc oxide (ZnO) wafer and a high-resistivity single crystal ZnO-based radiation detector, and preparation method and use thereof. The preparation method of the high-resistivity single crystal zinc oxide wafer is to place a single crystal ZnO wafer in a metal lithium electrochemical device for a constant-current discharge treatment, and then to place the single crystal ZnO wafer in a high-pressure oxygen atmosphere at 800 to 1000° C. and 10 to 30 atm for an annealing treatment for 20 to 28 hours. The preparation method of the radiation detector is to evaporate a metal electrode layer at both sides of the high-resistivity single crystal ZnO wafer, then to bond the wafer onto a circuit board, and to connect the wafer with the circuit board by a gold thread.

  • Patent number: 8853101
    Abstract: Methods for creating chemical guide patterns by DSA lithography for fabricating an integrated circuit are provided. In one example, an integrated circuit includes forming a bifunctional brush layer of a polymeric material overlying an anti-reflective coating on a semiconductor substrate. The polymeric material has a neutral polymeric block portion and a pinning polymeric block portion that are coupled together. The bifunctional brush layer includes a neutral layer that is formed of the neutral polymeric block portion and a pinning layer that is formed of the pinning polymeric block portion. A portion of the neutral layer or the pinning layer is selectively removed to define a chemical guide pattern. A block copolymer layer is deposited overlying the chemical guide pattern. The block copolymer layer is phase separated to define a nanopattern that is registered to the chemical guide pattern.
