| 20100307140 | METHOD TO MONITOR HC-SCR CATALYST NOX REDUCTION PERFORMANCE FOR LEAN EXHAUST APPLICATIONS - A method for initiating a regeneration mode in selective catalytic reduction device utilizing hydrocarbons as a reductant includes monitoring a temperature within the aftertreatment system, monitoring a fuel dosing rate to the selective catalytic reduction device, monitoring an initial conversion efficiency, selecting a determined equation to estimate changes in a conversion efficiency of the selective catalytic reduction device based upon the monitored temperature and the monitored fuel dosing rate, estimating changes in the conversion efficiency based upon the determined equation and the initial conversion efficiency, and initiating a regeneration mode for the selective catalytic reduction device based upon the estimated changes in conversion efficiency. | 12-09-2010 |
| 20110072790 | METHOD AND APPARATUS FOR MONITORING A HYDROCARBON-SELECTIVE CATALYTIC REDUCTION DEVICE - A method for monitoring a hydrocarbon-selective catalytic reactor device of an exhaust aftertreatment system of an internal combustion engine operating lean of stoichiometry includes injecting a reductant into an exhaust gas feedstream upstream of the hydrocarbon-selective catalytic reactor device at a predetermined mass flowrate of the reductant, and determining a space velocity associated with a predetermined forward portion of the hydrocarbon-selective catalytic reactor device. When the space velocity exceeds a predetermined threshold space velocity, a temperature differential across the predetermined forward portion of the hydrocarbon-selective catalytic reactor device is determined, and a threshold temperature as a function of the space velocity and the mass flowrate of the reductant is determined. If the temperature differential across the predetermined forward portion of the hydrocarbon-selective catalytic reactor device is below the threshold temperature, operation of the engine is controlled to regenerate the hydrocarbon-selective catalytic reactor device. | 03-31-2011 |
| 20110120089 | EXHAUST PARTICULATE MANAGEMENT FOR GASOLINE-FUELED ENGINES - A thin layer of low mean-pore-size filter material that permanently accommodates the accumulation of exhaust particulates (as soot or a soot cake) is carried on a porous ceramic support. The supported filter material is closely coupled with the exhaust manifold of the engine, for the purpose of passive regeneration of stored particulates, and removes particulate matter from the exhaust which is directed through the filter layer and ceramic support. The oxygen content of the exhaust oxidizes the particulate matter on the filter material. In a preferred embodiment, a thin layer of the filter material is supported on inlet channel walls of a wall flow-through ceramic filter body to remove the particles from the exhaust. The filter body comprises an upstream exhaust gas flow inlet face with openings to a plurality of inlet channels and a downstream face with a like plurality of openings from outlet channels. The inlet channels are closed at the downstream face and the outlet channels are closed at the inlet face. So the exhaust stream enters the inlet channels and flows through the filter layers and supporting channel walls to an outlet channel. The filtered exhaust stream exits the outlet end of the filter body and is combined into an exhaust passage downstream of the filter body for further treatment as may be necessary. | 05-26-2011 |

| 20110138539 | SYSTEM AND METHOD FOR IMPROVED PRESSURE ADJUSTMENT - A method for adjusting pressure within an air bed comprises providing an air bed that includes an air chamber and a pump having a pump housing, selecting a desired pressure setpoint for the air chamber, calculating a pressure target, adjusting pressure within the air chamber until a pressure within the pump housing is substantially equal to the pressure target, determining an actual chamber pressure within the air chamber, and comparing the actual chamber pressure to the desired pressure set-point to determine an adjustment factor error. The pressure target may be calculated based upon the desired pressure setpoint and a pressure adjustment factor. Furthermore, the pressure adjustment factor may be modified based upon the adjustment factor error determined by comparing the actual chamber pressure to the desired pressure setpoint. | 06-16-2011 |

| 20110110361 | SYSTEM FOR AND METHOD OF VALIDATING A VOIP TELEPHONE NUMBER ORDER - A system for and method of validating a VoIP telephone number order is presented. The described systems and methods may allow for corrupt telephone numbers to be discovered and placed in a corrupt telephone number pool. To this end, data may be mined from class 5 switches and VoIP routers and then compared to the telephone numbers in the order. If a telephone number is found to be corrupt, it may be removed from the order and stored in the corrupt telephone number repository for later review. The ordering process for any other requested telephone numbers may then continue on without interruption to the processing of the entire order. | 05-12-2011 |

| 20100301246 | SOLENOID VALVE - The invention relates to a solenoid valve with a magnet assembly and a valve cartridge having a pole core, a valve insert connected to the pole core, an armature which is guided within the valve insert in an axially movable manner between a closed position and an open position and is coupled to a closing element, and a valve body which is connected to the valve insert and has a main valve seat which is arranged between at least one first flow opening and a second flow opening. The axially movable armature, when the magnet assembly is energized, is moved by a generated magnetic force within the valve insert in the direction of the pole core counter to a spring force of a resetting spring and counter to a fluid force in order to lift the closing element out of the main valve seat; and to permit a flow of fluid between the at least one first flow opening and the second flow opening. The axially movable armature is moved away from the pole core by the spring force of the restoring spring and by the fluid force within the valve insert in order to press the closing element into the main valve seat in a sealing manner and to interrupt the fluid flow between the at least one first flow opening and the second flow opening. | 12-02-2010 |
