Publication number: 20170051698Abstract: Various methods and systems are provided for calibrating one or more exhaust valves. In one example, a system comprises an exhaust valve configured to control flow of exhaust gas exiting an engine and a controller configured to calibrate the exhaust valve by commanding the exhaust valve to a fully closed position with a first driving current and measuring a first position of the exhaust valve at the first driving current, commanding the exhaust valve to a fully open position with a second driving current and measuring a second position of the exhaust valve at the second driving current, and generating a map based on a linear function determined from the first driving current, the second driving current, the measured first position, and the measured second position. The controller is further configured to adjust a position of the exhaust valve based on the map.Type: ApplicationFiled: November 4, 2016Publication date: February 23, 2017Inventors: David Zielinski, Luke Michael Henry, Matthew John Malone, Harsha Vardhana

Patent number: 9574965Abstract: A monitoring system and method monitor changes in clearance distances between a sensor and a rotating component of a machine. Imbalance and/or wear in the machine is identified based on the changes in the clearance distances. The system and method optionally both measure the clearance distances and a rotating speed of the rotating component of the machine with the same sensor. In order to identify imbalance in the machine, a spectral energy of the machine can be calculated based on the changes in the clearance distances, and the imbalance in the machine can be identified based on the spectral energy. The system and method can determine a trigger speed of the machine that is associated with the wear in the machine based on the changes in the clearance distance. A remaining useful life of the machine can be estimated based on changes in the trigger speed.Type: GrantFiled: June 24, 2014Date of Patent: February 21, 2017Assignee: General Electric CompanyInventors: Anthony Furman, Aninda Bhattacharya, Matthew John Malone, Mahesh Raveendranatha Panicker

Patent number: 9550535Abstract: An aerodynamic control system includes a skirt assembly configured to be disposed between plural vehicles in a vehicle system formed from the plural vehicles with the vehicles separated by a spatial gap in the vehicle system. The skirt assembly can include a bladder configured to be inflated with a fluid by a fluid source disposed onboard the vehicle system to cause the skirt assembly to expand between the vehicles from a collapsed state to an expanded state such that the skirt assembly at least partially fills the spatial gap between the vehicles. The skirt assembly can reduce aerodynamic drag exerted on the vehicle system during movement of the vehicle system relative to the vehicle system moving without the skirt assembly in the expanded state.Type: GrantFiled: April 17, 2015Date of Patent: January 24, 2017Assignee: General Electric CompanyInventors: Matthew John Malone, Gregory Wright

Patent number: 9308921Abstract: A system is provided for use with, a wheeled vehicle. The system includes a media reservoir capable of holding a tractive material that includes particulates; a nozzle in fluid communication with the media reservoir; and a media valve in fluid communication with the media reservoir and the nozzle. The media valve is controllable between a first state in which the tractive material flows through the media valve and to the nozzle, and a second state in which the tractive material is prevented from flowing to the nozzle. In the first state, the nozzle receives the tractive material from the media reservoir and directs the tractive material to a contact surface such that the tractive material impacts the contact surface that is spaced from a wheel/surface interface. The system can modify the adhesion or the traction capability of the contact surface with regard to a subsequently contacting wheel.Type: GrantFiled: July 5, 2011Date of Patent: April 12, 2016Assignee: General Electric CompanyInventors: Bret Dwayne Worden, Ajith Kuttannair Kumar, Matthew John Malone, Jennifer Lynn Coyne, Nikhil Subhashchandra Tambe, Milind Bharat Garule, Anubhav Kumar
