| 20090041641 | HYDROGEN PURIFICATION PROCESS AND SYSTEM - A hydrogen generation system is disclosed that includes a fuel reforming reactor generating a hydrogen-rich reformate gas at a temperature greater than 150 C., a pressure swing adsorption (PSA) hydrogen purification unit that separates the reformate gas into a relatively pure hydrogen stream and an off-gas stream, and a catalytic reactor down stream of the PSA unit that converts carbon monoxide (CO) and hydrogen (H | 02-12-2009 |
| 20090166264 | MULTI-STAGE SULFUR REMOVAL SYSTEM AND PROCESS FOR A FUEL SYSTEM - A system for producing an auxiliary fuel stream containing a low concentration of sulfur compounds from a primary fuel stream includes a first separation stage to separate a portion of a primary fuel stream into a first vapor permeate stream and a first retentate stream, a first separation stage partial condenser connected to the first vapor permeate stream condensing a portion of the first vapor permeate stream into a first liquid stage stream and a first vapor stage stream, and a second separation stage partial condenser condensing a portion of the first vapor stage stream into a second liquid stage. The first vapor permeate stream is preferable sent through a vapor phase reactive desulfurization catalyst reactor to condition any sulfur compounds present into species that can be easily separated from the fuel stream. The process includes isolating a first vapor permeate stream and a first retentate stream from a primary fuel stream by passing a portion of the primary fuel stream through a first membrane separation stage, condensing a portion of the first vapor permeate stream in a first separation stage partial condenser into a first liquid stage stream and a first vapor stage stream, and passing the first vapor stage stream through a desulfurization reactor. The stream may then be processed through a sorbent bed to effectively remove the sulfur compounds. | 07-02-2009 |
| 20090220394 | STEAM REFORMING UNIT - A hydrogen generation system is disclosed that includes an integrated steam reforming reactor. The reactor has an overall cylindrical shape, receives a reformate and separately receiving a combustion gas mixture. The reactor includes a plurality of reforming stages arranged in a stacked series of disc shaped stage configuration, wherein each reforming stage has a disc shaped combustion portion adjacent a disc shaped catalyst pack through which the reformate passes, wherein the reformate is directed axially between stages and radially within each stage; and the combustion mixture is directed radially between groups of stages and circumferentially within each stage. | 09-03-2009 |
| 20100172827 | FUEL STEAM REFORMER SYSTEM AND REFORMER STARTUP PROCESS - A hydrogen generation system is disclosed that has a vaporization section receiving and vaporizing fuel along with water and passing the vapor to a reformer catalyst section heated by a combustor section which generates reformate gas and is fueled by off-gas from a H | 07-08-2010 |

| 20100049400 | VEHICLE DISTURBANCE ESTIMATOR AND METHOD - A Vehicle Disturbance Estimator determines estimates of a vehicle disturbance force according to vehicle operating conditions. The determined vehicle disturbance force estimate can be used, for example, in connection with controlling a cruise control system for the vehicle, in connection with fuel economy evaluations and testing, and in connection with vehicle diagnostics. A plurality of sets of inputs can be used to determine plural vehicle disturbance estimates for time periods during which a cruise control is on, the vehicle is being driven in the highest gear, and the vehicle is not being braked by any brakes. The plurality of vehicle disturbance estimates can be averaged to provide an output corresponding to an average vehicle disturbance estimate over a plurality of sampling time periods. Kalman filtering can be used to determine the vehicle disturbance estimates. Signals corresponding to the plural disturbance estimates can be provided as an input to a cruise control, with the cruise control then being operable to control the speed of the motor vehicle, based at least in part upon the vehicle disturbance estimate. | 02-25-2010 |
| 20110106388 | VEHICLE TORQUE MANAGEMENT - A torque management system and method is described by which the torque provided by an engine can be controlled based on a mass of the vehicle and, if available, instantaneous and/or predictive slope information. Also, in some modes of operation, torque can be controlled based on speed limit information for upcoming road segments to be traveled by a vehicle. In addition to controlling the maximum allowable torque, optionally the minimum allowable torque can also be controlled to prevent inadvertent decelerations of the vehicle. A driver/operator can optionally override the torque control and the history of override requests can optionally be used to adjust overrides of the system. A plurality of torque control approach sub-methods can be made available with the appropriate sub-mode being selected depending, for example, upon the extent of the available information. | 05-05-2011 |
| 20110218715 | Drive train control arrangement - In a drive train control arrangement for a motor vehicle drive train, which comprises at least one main drive train, a first drive axle driven permanently by means of the main drive train, at least one auxiliary drive train and a second drive axle coupleable to the main drive train via the auxiliary drive train, which has a first clutch unit and at least a second clutch unit connected downstream in the power train of the first clutch unit for connecting the second drive axle to the main drive train, and a control unit, which in at least one operating mode

| 20110246013 | VEHICLE POWER SYSTEM WITH FUEL CELL AUXILIARY POWER UNIT (APU) - A power distribution system comprises at least one fuel cell that is selectively operated in response to conditions to provide power to electrical loads and/or to charge an electrical storage device such as a vehicle battery. One form of an alternator can be selectively engaged or disengaged to provide power to the electrical loads and/or to charge the electrical storage device. Either or both of the fuel cell and alternator can be operated to provide electrical power. | 10-06-2011 |
