Patent number: 9496748Abstract: Systems and methods for controlling a hybrid power architecture to provide fuel or energy savings. Recharge time of an energy storage device (ESD) is reduced through the application of a controlled potential and ESD recharge time management over the life of the hybrid system through manipulation of the ESD charge state window of operation. Fuel or energy savings is achieved by controlling the partial-state-of-charge (PSOC) window of the ESD based on a recharge resistance profile of the ESD and by controlling a charging potential applied to the ESD based on a recharge current and/or the estimated recharge resistance profile of the ESD.Type: GrantFiled: July 12, 2012Date of Patent: November 15, 2016Assignee: General Electric CompanyInventors: Christopher James Chuah, Herman Lucas Norbert Wiegman, Donald Wayne Whisenhunt, Jr., Roger Neil Bull, Kalyan Bukkasamudram, Connor Brady, Mark Gotobed

Patent number: 9272271Abstract: A method of producing a catalyst composition is provided, the method comprising mixing (i) a first component comprising a zeolite, and (ii) a second component comprising a homogeneous solid mixture containing at least one catalytic metal and at least one metal inorganic support, wherein the first component and the second component form an intimate mixture, and wherein the homogeneous solid mixture is produced by mixing a reactive solution comprising a precursor of the metal inorganic support and a templating agent with a precursor of the catalyst metal, and calcining the mixture to form the homogeneous solid mixture. The templating agent affects one or more of pore size, pore distribution, pore spacing, or pore dispersity of the metal inorganic support. The pores of the solid mixture produced after calcination may have an average diameter in a range of about 1 nanometer to about 15 nanometers.Type: GrantFiled: June 20, 2014Date of Patent: March 1, 2016Assignee: General Electric CompanyInventors: Larry Neil Lewis, Donald Wayne Whisenhunt, Jr., Dan Hancu, Ashish Balkrishna Mhadeshwar, Benjamin Hale Winkler, Daniel George Norton, Oltea Puica Siclovan, Ming Yin
