  • Patent number: 11002552
    Abstract: A slope sample value at a sample point on a target route and a distance sample value from a reference point on the target route to the sample point are calculated based on three-dimensional position data of the target route. Undetermined elements contained in a model formula for the approximation formula representing relation between the slope sample value and the distance sample value are determined using an error evaluation formula for the model formula. The error evaluation formula contains a slope error evaluation component for evaluating a slope error between the slope sample value and a slope model value that is calculated using the model formula, and an altitude error evaluation component for evaluating an altitude error between an altitude model value that is obtained through integration of the slope model value and an altitude value that is obtained from the three-dimensional position data.

  • Patent number: 11004983
    Abstract: An object is to provide a memory device including a memory element that can be operated without problems by a thin film transistor with a low off-state current. Provided is a memory device in which a memory element including at least one thin film transistor that includes an oxide semiconductor layer is arranged as a matrix. The thin film transistor including an oxide semiconductor layer has a high field effect mobility and low off-state current, and thus can be operated favorably without problems. In addition, the power consumption can be reduced. Such a memory device is particularly effective in the case where the thin film transistor including an oxide semiconductor layer is provided in a pixel of a display device because the memory device and the pixel can be formed over one substrate.

  • Publication number: 20200149885
    Abstract: The interior of a first measurement surface and the interior of a second measurement surface traveling together with a measuring vehicle are scanned to acquire first measurement coordinate points and second measurement coordinate points, respectively. A first comparison point cloud representing a comparison part on a surface of a structure is extracted from the first measurement coordinate points. A second comparison point cloud representing a comparison part on the surface of the structure is extracted from the second measurement coordinate points. A difference between the first comparison point cloud and the second comparison point cloud corresponding to measurement of a common comparison part on the surface of the structure is calculated. Error having time dependence included in the first measurement coordinate points and the second measurement coordinate points is calculated on the basis of the calculated difference. The measurement coordinate points are corrected on the basis of the calculated error.
