  • Patent number: 10983236
    Abstract: Post-stack seismic data is received. Transformed seismic data is created from the received post-stack seismic data, including performing a super-resolution radon transform on the post-stack seismic data. Signal and noise regions are separated using the transformed seismic data, including using a defined muting function to remove unwanted noise. An inverse radon transform is performed using the separated signal and noise regions, outputting only signals.

  • Patent number: 10983231
    Abstract: A computer calculates a change amount of a total number of electrons from an observation start time in the ionosphere between an observation station and a satellite based on observation data of a signal received from the satellite by the observation station on the ground. The computer estimates the change amount of the total number of electrons to be calculated next based on the time change of the change amount of the total number of electrons from the observation start time in the ionosphere and calculates a difference (estimation error) between the estimated change amount of the total number of electrons and the actually calculated change amount of the total number of electrons. The computer calculates a correlation value between the estimation error calculated for each observation station and the estimation error calculated for a predetermined number of the observation stations in the vicinity of each observation station.

  • Patent number: 10955261
    Abstract: An air data computer senses acceleration and rotational rate of an aircraft with an inertial sensor assembly of the air data computer. The air data computer determines first attitude information of the aircraft based on the acceleration and rotational rate sensed with the inertial sensor assembly. The air data computer receives second attitude information of the aircraft from a source external to the air data computer, and determines attitude correction values based on the first attitude information and the second attitude information. The air data computer applies the attitude correction values to the first attitude information to produce error-corrected attitude information that is output from the air data computer.

  • Patent number: 10948536
    Abstract: The invention is a truth table-based failure isolation matrix in an Automated Test Equipment (ATE) environment to enable the mapping of measured results and/or test outcomes to probable causes of failure (PCOF). The failure isolation matrix is hierarchical in that it applies to both individual tests as well as groups of tests. For each level in the hierarchy, columns represent individual outcomes verified against expected results to produce a resultant outcome and rows represent possible combinations of measurement outcomes or outcome vectors. For groups of tests, the measurement results represent the combined results of the individual tests within the test group. The resultant matrix is a pattern of vectors that can be pattern matched against prior history of result patterns to further improve the accuracy and narrow the scope of PCOF.
