Patent number: 6759951Abstract: A method and system for a lead mobile asset to verify that a remote mobile asset under the control of the lead mobile asset is following a set of command functions broadcast by the lead mobile asset in a command message. The lead and remote mobile assets may be part of a train consist equipped with a distributed power communication system. The method includes determining whether the lead mobile asset has received a status reply message from the remote mobile asset, the reply message transmitted in response to the remote mobile asset's receipt of the command message and including data indicative of at least one operational state of the remote mobile asset. A help command message may be broadcast from the lead mobile asset if the lead mobile asset has not received the status reply message from the remote mobile asset.Type: GrantFiled: October 24, 2002Date of Patent: July 6, 2004Assignee: General Electric CompanyInventors: Steven Andrew Kellner, Robert Francis Bryant

Patent number: 6691064Abstract: Computerized method and system for identifying repeatedly malfunctioning equipment and root causes therefor are provided. The method allows to provide a database comprising detailed equipment data including data indicative of historical equipment malfunctions in a plurality of pieces of equipment. The equipment data includes a unique equipment identifier for uniquely relating each malfunction to respective equipment. The method further allows to analyze the data base for a selected time window to review equipment malfunctions logged in the database and resulting in servicing activities over that time window. An equipment malfunction threshold for the number of malfunctions occurring during a predetermined period of time is established.Type: GrantFiled: April 20, 2001Date of Patent: February 10, 2004Assignee: General Electric CompanyInventor: Douglas Scott Vroman

Patent number: 6650949Abstract: A method for sorting respective incident log data from a plurality of machines undergoing diagnostics is provided. The method allows for receiving incident log data comprising one or more incidents from the plurality of machines and for receiving operational parameter data from the plurality of machines. The method further allows for executing a set of incident-authentication rules indicative of whether a received incident actually corresponds to a faulty condition or not. An assigning step allows for assigning a predetermined incident severity rating to the respective incidents, and a processing step allows for processing the respective incidents based on their respective incident severity rating.Type: GrantFiled: March 9, 2000Date of Patent: November 18, 2003Assignee: General Electric CompanyInventors: Gregory J. Fera, Christopher M. McQuown, Bryan S. Reichenbach, Edward P. Wisniewski

Patent number: 6636771Abstract: The present invention discloses system and method for analyzing continuous parameter data from a malfunctioning locomotive or other large land-based, self-powered transport equipment. The method allows for receiving new continuous parameter data comprising a plurality of anomaly definitions from the malfunctioning equipment. The method further allows for selecting a plurality of distinct anomaly definitions from the new continuous parameter data. Respective generating steps allow for generating at least one distinct anomaly definition cluster from the plurality of distinct anomaly definitions and for generating a plurality of weighted repair and distinct anomaly definition cluster combinations. An identifying step allows for identifying at least one repair for the at least one distinct anomaly definition cluster using the plurality of weighted repair and distinct anomaly definition cluster combinations.Type: GrantFiled: October 13, 2000Date of Patent: October 21, 2003Assignee: General Electric CompanyInventors: Anil Varma, Nicholas Edward Roddy, David Richard Gibson

Patent number: 6622264Abstract: A process for analyzing fault log data from a machine is provided. The process allows for downloading new fault log data from the machine. The process further allows for retrieving prior fault log data of the machine. The prior fault log data may be obtained during an earlier download relative to a present download of new fault log data. A comparing step allows for comparing the new fault log data against the prior fault log data, and an adjusting step allows for adjusting any repair recommendations for the earlier download of fault log data based upon the comparison of the new fault log data and the prior fault log data.Type: GrantFiled: November 22, 1999Date of Patent: September 16, 2003Assignee: General Electric CompanyInventors: Richard G. Bliley, Nicholas E. Roddy

Patent number: 6600979Abstract: Method and system for determining a reference speed indicative of true ground speed of a vehicle having a plurality of axles are provided. The reference speed for a designated one of the axles is dynamically adjusted to account for changes in vehicular acceleration that may occur while determination of the reference speed is being performed. The method allows collecting a stream of samples over respective sampling intervals of at least one motion-indication parameter corresponding to a respective axle of the vehicle. In one aspect thereof, one may use a torque reduction rulebase configured to avoid high torque reduction, and inaccuracies in the motion-indication parameter due to high levels of creep, if any, in a wheel of the respective axle. The method further allows estimating an inertia value for the vehicle based on respective changes in tractive effort and acceleration over each sampling interval.Type: GrantFiled: February 26, 2002Date of Patent: July 29, 2003Assignee: General Electric CompanyInventors: Ajith K. Kumar, Bret Dwayne Worden, Roland Paul Donajkowski

Patent number: 6571776Abstract: A method for controlling start of a compression ignition engine having a plurality of cylinders is provided without a cam sensor is provided. Each cylinder includes a respective piston reciprocally movable between respective top and bottom positions along a cylinder longitudinal axis. The method comprises proving a respective fuel delivery assembly for each cylinder. In one embodiment the method further comprises retrieving from memory a set of fuel delivery assembly firing rules and then processing the firing rules so that a firing signal is delivered to each fuel delivery assembly on every crank revolution during a cranking mode of operation. The fuel delivery assembly is arranged to be responsive to any firing signal received during an injection window leading to the top position along the longitudinal axis so as to supply fuel to each cylinder during the injection window.Type: GrantFiled: September 8, 2000Date of Patent: June 3, 2003Assignee: General Electric CompanyInventor: Vince F.
