Patent number: 8755941Abstract: A method and system for controlling a temperature of an exhaust gas being introduced to a catalyst is provided. Using an adjustable flow controller, an adjustable amount of tempering fluid is provided to the exhaust gas prior to the exhaust gas proceeding to the catalyst. A sensor senses a parameter indicative of a temperature of the exhaust gas being introduced to the catalyst. A computer processor uses a relationship to relate the parameter to an adjustment of the adjustable flow controller that will adjust the amount of tempering fluid provided to the exhaust gas and change the temperature of the exhaust gas being introduced to the catalyst toward a target temperature. Adjustment of the adjustable flow controller is initiated by the computer processor to change the flow of the tempering fluid, and the relationship between the parameter and the adjustment of the adjustable flow controller is updated.Type: GrantFiled: September 2, 2010Date of Patent: June 17, 2014Assignee: General Electric CompanyInventors: Larry William Swanson, Douglas Frank Beadie, Neil Colin Widmer, Hua Zhang, Gilbert Otto Kraemer

Patent number: 8751100Abstract: A method for performing diagnostics or software maintenance on a vehicle comprises storing components of configuration files in a central processing system. An update of the configuration files is requested for the vehicle from a central electronic data processing system based on a user request. The requested update of components of configuration files are received from the central electronic data processing system based on a comparison of a record of the vehicle-installed configuration files and target configuration information on configuration files stored at the central electronic data processing system.Type: GrantFiled: September 10, 2010Date of Patent: June 10, 2014Assignee: Deere & CompanyInventors: Michael R. Johnson, Daniel Colavita, Tammy R. Pullen

Publication number: 20140148928Abstract: A system and approach for development of setpoints for a controller of an engine or powertrain. The controller may be parametrized as a function of setpoints to provide performance variables that are considered acceptable by a user or operator for normal operating conditions of the engine or powertrain. With each iteration of the setpoints, the controller may be reconfigured to provide more stable and dynamically performant control of the engine or powertrain. The present system and approach may automate a previously labor intensive approach for designing setpoints for the controller.Type: ApplicationFiled: November 27, 2012Publication date: May 29, 2014Applicant: HONEYWELL INTERNATIONAL INC.Inventor: Gregory E.

Patent number: 8725303Abstract: A multi-dimensional energy control system is provided with an energy management software application that organizes the consumption of energy by a device as an n-dimensional energy space, where n is an integer greater than 2, and each axis in the energy space represents an energy consumption characteristic. The energy management application generates instructions for a device in response to calculating a compromise operating point in the energy space. A user interface (UI) connected to the energy management application has a display to receive a graphical representation of the energy space and compromise operating point, and an input to receive user commands for moving the represented compromise operating point in the represented energy space. The energy management application calculates the compromise operating point in the energy space to match the displayed compromise operating point.Type: GrantFiled: July 8, 2011Date of Patent: May 13, 2014Assignee: Sharp Laboratories of America, Inc.Inventors: Daniel J. Park, James E. Owen, Carl Mansfield, David Elrod

Patent number: 8706814Abstract: In one embodiment, the present invention is a method and apparatus for layering agents in a distributed computing system. In one embodiment, a system for monitoring and controlling a distributed computer network including a plurality of components (e.g., devices) includes a plurality of cells, each of the cells being deployed to directly monitor and control one of the components of the network. The system also includes at least one federation, where the federation is made up of cells that cooperate to solve common problems, and at least one supercell, where the supercell provides supplemental decision making capabilities to the cells and federations. In this manner, problems detected by a cell that cannot be resolved by the cell may be forwarded to the cell's associated federations or supercells for resolution.Type: GrantFiled: September 1, 2012Date of Patent: April 22, 2014Assignee: AT&T Intellectual Property II, L.P.Inventor: James Pelletier

Publication number: 20140107993Abstract: A process characteristic parameter determination system uses a process model and a tuning module to accurately determine a value for a process characteristic parameter within a plant without measuring the process characteristic parameter directly, and may operate on-line or while the process is running to automatically determine a correct value of the process characteristic parameter at any time during on-going operation of the process. The process characteristic parameter value, which may be a heat transfer coefficient value for a heat exchanger, can then be used to enable the determination of a more accurate simulation result and/or to make other on-line process decisions, such as process control decisions, process operational mode decisions, process maintenance decisions such as implementing a soot blowing operation, etc.Type: ApplicationFiled: October 12, 2012Publication date: April 17, 2014Applicant: EMERSON PROCESS MANAGEMENT POWER & WATER SOLUTIONS, INC.Inventor: Xu Cheng

Patent number: 8688277Abstract: An apparatus that generates brewed beverages by performing one or more chemical and/or mechanical processes may receive requests to produce specified brewed beverages. The apparatus may include a master controller that initiates and controls performance of the chemical and/or mechanical processes to produce the specified beverages. The master controller may adaptively apply one or more process accelerators during the performance of one of the chemical or mechanical processes to accelerate the process or to achieve a desired qualitative or quantitative characteristic for a beverage or a component thereof. The adaptive application of one or more process accelerators may be dependent on a multiple-variable process profile developed for the process and/or a specified beverage. For example, the pressure in a steam wand and/or the depth of the wand may be varied during a process to froth milk in order to produce frothed milk having a desired temperature.Type: GrantFiled: January 26, 2012Date of Patent: April 1, 2014Assignee: Briggo, Inc.Inventors: Charles F.
