Patent number: 9249737Abstract: A sensor apparatus and methods for facilitating combustion of a gaseous fuel are provided. The sensor apparatus comprises a combustion apparatus defining a combustion chamber therein. The combustion apparatus is configured to combust a fuel-air mixture within the combustion chamber to produce at least one combustion product. At least one optical diagnostic apparatus is coupled to the combustion apparatus for measuring at least one property of the at least one combustion product within the combustion chamber. A controller is coupled to the at least one optical diagnostic apparatus, and is configured to determine the Wobbe index of the fuel in real-time based on the measured at least one property of the at least one combustion product and pre-determined combustion state data stored within the controller.Type: GrantFiled: February 26, 2013Date of Patent: February 2, 2016Assignee: General Electric CompanyInventors: Russell Paul Fitzgerald, Patrick Edward Pastecki, Danielle Marie Kalitan, Gary Lee Leonard

Patent number: 9146181Abstract: A contaminant detection system has a fluid path. A meter and a plurality of fluid conduits are disposed along the fluid path. The meter is configured to detect an operating parameter of a fluid. The plurality of fluid conduits forms a plurality of intermediate fluid paths. Each fluid conduit has a restriction orifice (RO), an inlet control valve, and an outlet control valve. In addition, the plurality of fluid conduits has a control line and an exposed line. The control line is configured to be isolated from the fluid for a time period. The exposed line is configured to be exposed to the fluid for the time period. The system is configured to determine a contaminant concentration of the fluid at least in part using the operating parameter and the time period.Type: GrantFiled: July 27, 2012Date of Patent: September 29, 2015Assignee: Generel Electric CompanyInventors: Patrick Edward Pastecki, Joe Schornick, Michal Marek Knapczyk

Patent number: 8961891Abstract: A heat sink is used to absorb heat produced by a vehicle. The heat sink uses an endothermic catalytic alcohol dehydrogenation reaction to assist with the absorption of excess heat produced in the electronics of the vehicle. In some embodiments, the alcohol can be pre-heated by absorbing heat from various components of the vehicle. Excess heat from the various components or from the vehicle engine can be used to vaporize the reaction fluids in order to further absorb additional heat. Reaction fluids can also be sent to the vehicle's engine/burner for use as a supplemental fuel.Type: GrantFiled: August 20, 2010Date of Patent: February 24, 2015Assignee: Lockheed Martin CorporationInventors: Ashish B. Mhadeshwar, Daniel Norton, Robert James Perry, Paul Glaser, Patrick Edward Pastecki
