Patent number: 7557748Abstract: The present invention, in one aspect, is a method for determining motion and/or location parameters of a locomotive. One method embodiment includes steps of phase locking a pair of receivers having antennas at different locations on a locomotive to reference signals received from a set of satellites, determining a set of phase differences between the reference signals received at the antennas, and determining at least one of an accurate heading, heading rate, attitude, and attitude rate of the locomotive using the set of phase differences between the reference signals.Type: GrantFiled: June 1, 2000Date of Patent: July 7, 2009Assignee: General Electric CompanyInventors: Charles L.

Patent number: 7558740Abstract: A scheduling system and method for moving plural objects through a multipath system described as a freight railway scheduling system. The scheduling system utilizes a cost reactive resource scheduler to minimize resource exception while at the same time minimizing the global costs associated with the solution. The achievable movement plan can be used to assist in the control of, or to automatically control, the movement of trains through the system.Type: GrantFiled: August 18, 2004Date of Patent: July 7, 2009Assignee: Harris CorporationInventors: William L. Matheson, Paul M. Julich, Michael S. Crone, Douglas A. Thomae, Thu V. Vu, M. Scott Wills

Patent number: 6459965Abstract: A method is provided for controlling movement of a plurality of vehicles over a guideway partitioned into a plurality of guideway blocks. The method uses a control system including an onboard computer (OBC) located on board each vehicle, at least one server for communicating with the OBCs, and a vehicle tracking system. The method including the steps of determining a composite block status for all guideway blocks, broadcasting the composite block status to the OBCs, and controlling movement of each vehicle based on the composite block status.Type: GrantFiled: June 18, 2001Date of Patent: October 1, 2002Assignee: GE-Harris Railway Electronics, LLCInventors: Alan L. Polivka, James R. Egnot, Robert E. Heggestad, Jeffrey K. Baker, William L. Matheson

Patent number: 6374184Abstract: A path determination device is configured to receive measured heading and distance information; determine heading corrections, distance corrections, and residuals utilizing a Kalman filter assuming a selected, known path was taken; and to determine a probability that the selected, known path actually was taken utilizing the determined residuals. The additional information utilized by the Kalman filters provides a more robust measurement indication of whether a particular path is taken than mere measurements and correlations of path curvature.Type: GrantFiled: June 1, 2000Date of Patent: April 16, 2002Assignee: GE-Harris Railway Electronics, LLCInventors: Charles L.
