Abstract: Device for checking the integrity of a digital transmission for an analog output of a system. The analog output may be checked for transient errors that can be attributed to a digital transmission path embedded somewhere within the vehicle system. A test signal is introduced into a digital transmission that can be reassembled from an analog path of the analog output, and, if not, allows the test device to pinpoint that errors are appearing due to the digital path, and not because of the analog output. In this way, debugging an installation of a system becomes easier; obtaining confidence in reliability of a mixed analog and digital system becomes less of a challenge and less time consuming.

Abstract: Turning points in stratigraphy (TPS) can be determined, which then can be used to improve the representation of the borehole path in relation to layers of the subterranean formation. The TPS can be determined by analyzing each directional survey point in relation to the nearest layer of the subterranean formation. In determining which layer is the nearest layer, the process can analyze the layer type, such as conformable or unconformable, whether a fault intersects the borehole, the angle of the layer in relation to the borehole path, or whether the true stratigraphic thickness (TST) changes from one of a positive parameter or negative parameter to the other. The generated TPS can be used by a system as input or can be displayed for a user where the segmented borehole path can be aligned using the calculated TST to improve the ability of the user to analyze the representation.

Abstract: A system to detect and control noise in seismic surveys is provided. The system receives, responsive to a seismic wave generated by a source, seismic data detected by a sensor component of a seismic data acquisition unit. The system generates, for windows of the seismic data, Hough tensors for seismic data transforms in multiple dimensions. The system detects, based on a comparison of an eigenvector and eigenvalue of a canonical matrix of the Hough tensors with a historical eigenvector and eigenvalue of a historical canonical matrix of historical Hough tensors of historical seismic data, a first presence of noise in the seismic data. The first presence of noise can correspond to a noisy spectra pattern in a seismic data transform of the seismic data. The system provides, responsive to detection of the first presence of noise in the seismic data, a notification to adjust a characteristic of the seismic survey.
