Patent number: 11466638Abstract: An engine diagnostic system includes a control system having a controller operatively connected to an engine. A monitoring system has a sensor operatively connected to the engine. A diagnostic system is operatively connected to the engine. The diagnostic system is configured to implement a sensor diagnostic procedure that includes a sensor health test. The sensor health test includes comparing a measured value of a sensor to an expected value and determining the health of the sensor based on the difference between the measured value and the expected value. The sensor diagnostic procedure can also include telematics data analysis.Type: GrantFiled: October 24, 2017Date of Patent: October 11, 2022Assignee: DEERE & COMPANYInventors: Jason E. Brinkman, Joseph A. Bell, Curtis P. Ritter, Mark A. Friedrich, Michael J. Pipho

Patent number: 9765690Abstract: Systems and methods are provided for a diagnostic system for a machine with a combustion engine and a variable geometry turbocharger that includes a vane position sensor. The diagnostic system includes a controller configured to calculate a learned span value of the turbocharger based on the output of the vane position sensor during a diagnostic procedure and a reference vane position sensor value. A plurality of learned span values are calculated each during a different one of a plurality of diagnostic procedures performed over a period of time and a first regression analysis to predict an expected learned span value at a defined future time using the calculated learned span value and the plurality of stored learned span values. An alert message is generated when the expected learned span value is indicative of a potential future fault of the turbocharger.Type: GrantFiled: September 30, 2015Date of Patent: September 19, 2017Assignee: Deere & CompanyInventors: Curtis P. Ritter, Brigham R. Shamrell, Michael J. Ryken, Stephane Cochet, Jeffrey M. Hedberg, Zachary M. Sharp, Joseph A. Bell, Mark A. Friedrich

Patent number: 9563492Abstract: A service diagnostic trouble code sequencer and method is disclosed that includes receiving multiple diagnostic trouble codes (DTCs), determining which DTCs to diagnose first, and recommending which DTC(s) to diagnose first. The sequencer can recommend a category of DTCs to diagnose first, where the category of DTCs includes one or more DTCs. The sequencer can prioritize the DTCs in the category of DTCs. The sequencer can separate the DTCs into multiple categories of DTCs, and prioritize the multiple categories of DTCs. The sequencer can prioritize the DTCs in an ordered category of the multiple categories of DTCs. The sequencer can receive the plurality of DTCs locally or remotely over a network. The sequencer can output the one or more DTCs to diagnose first locally or remotely over a network. The sequencer can be resident on the machine generating the DTCs.Type: GrantFiled: January 9, 2015Date of Patent: February 7, 2017Assignee: Deere & CompanyInventors: Joseph A Bell, Curtis Paul Ritter, Kelly R Carpenter, Brigham R Shamrell, Mark A Friedrich

Patent number: 8474115Abstract: A method of collecting a strand using an air stream dissipater comprises texturizing the strand with an air stream on a first side of the air stream dissipater, directing the texturized strand through the air stream dissipater and collecting the texturized strand in a container on the second side of the air stream dissipater. A system for texturizing a strand comprises a texturizer for texturizing the strand with an air stream, a container to collect and hold the texturized strand and an air stream dissipater provided between the texturizer and the container to dissipate excess air from the air stream and prevent the excess air from entering the container.Type: GrantFiled: August 28, 2009Date of Patent: July 2, 2013Assignee: OCV Intellectual Capital, LLCInventors: Norman T. Huff, Janakikodandaram Karra, Gareth Knoll, Mark A. Friedrich
