20080199743 | Ambient Pressure Fuel Cell System Employing Partial Air Humidification - A fuel cell system is provided that is capable of operating at high temperatures and near-ambient pressure with partial humidification of air supplied to the fuel cell stack. The fuel cells of the stack incorporate gas diffusion barrier layers at the cathode side thereof. The system includes a cooling loop for circulating a liquid coolant through the stack. In some embodiments, an incoming air stream is partially humidified with water vapor transferred from a cathode exhaust stream in a gas-exchange humidifier or enthalpy wheel. In other embodiments, a cathode recycle is employed to partially humidify the incoming air. The humidity of the air and cathode exhaust streams is maintained below a stack saturation point. Methods of operating the fuel cell system are also provided. | 08-21-2008 |
20090258256 | SYSTEM AND METHOD OF STARTING A FUEL CELL SYSTEM - A system and method for starting up a fuel cell system are disclosed. Briefly described, an embodiment for starting an electrochemical reaction between a fuel and an oxidant during a start-up process includes a fuel cell stack operable to output a nominal voltage during a normal operating condition and operable to output a reduced start-up voltage during the start-up process, and includes at least one balance of plant (BOP) device that supports operation of the fuel cell stack, operable at a nominal output when sourced by the fuel cell stack at the nominal voltage, and operable at a reduced output when sourced by the fuel cell stack at the reduced start-up voltage. | 10-15-2009 |
20110070511 | COOLING SUBSYSTEM FOR AN ELECTROCHEMICAL FUEL CELL SYSTEM - Improvements in startup time for an electrochemical fuel cell system from freezing and sub-freezing temperatures may be observed by minimizing the coolant volume in the coolant subsystem. In particular, this may be accomplished by having a two pump—dual loop cooling subsystem. During startup, one pump directs coolant through a startup coolant loop and after either the fuel cell stack or the coolant temperature reaches a predetermined threshold value, coolant from a main or standard coolant loop is then directed to the fuel cell stack. In an embodiment, coolant from the standard loop mixes with coolant in the startup loop after the predetermined threshold temperature is reached. | 03-24-2011 |

20100050153 | METHOD AND SYSTEM OF EDITING WORKFLOW LOGIC AND SCREENS WITH A GUI TOOL - A workflow management system provides a graphical user interface (GUI) tool that allows a user to create and/or edit workflow logic without requiring the re-writing and recompiling of the application software, and without interrupting the operability of the application software at any time. The GUI tool allows the user to simultaneously view and create and/or edit the corresponding application screen where the workflow logic is applied in the application software, while the user creates and/or edits the workflow logic. The user creates and/or edits the workflow logic by selectively combining the available parameters that are provided in spoken language syntax by a context sensitive menu. The workflow logic statements are made available for the application software to call at the appropriate times. The GUI tool works in conjunction with a dynamically configurable database. | 02-25-2010 |
20110119604 | SYSTEM AND METHOD FOR A CONFIGURABLE AND EXTENSIBLE ALLOCATION AND SCHEDULING TOOL - A system provides a GUI allocation and scheduling tool that enables a user to configure and apply Schedule Flows that include scheduling logic statements, filters, matching functions, scheduling engines and Objective Functions to appropriately assign a plurality of jobs to a plurality of workers and resources. The user may add, delete and/or edit scheduling logic statements, filters, matching criteria, scheduling engines and Objective Functions to produce appropriate scheduling outcomes according to user definable objectives. The GUI tool also enables a user to evaluate scheduling outcomes and assess the effectiveness of Schedule Flows and scheduling logic statements by configuring and applying evaluation criteria. The system's platform architecture provides software interfaces that enable the integration of custom matching functions, scheduling engines and Objective Functions, and third party hardware and software functionality. | 05-19-2011 |
20130006696 | SYSTEM AND METHOD FOR AN EXTENSIBLE WORKFLOW MANAGEMENT - A workflow management system provides a GUI Configurability tool that allows an end user to configure the system's workflow screens, workflow logic and data fields without the need to rewrite any programs. The system allows each workflow screen to represent and assist each individual task within a business process that may be defined and illustrated by a flowchart. The workflow screens work in conjunction with workflow logic to create an accurate one-to-one mapping of the individual tasks and decision logic within a business process flowchart. The system provides published interfaces that allow the use of third party hardware and software within workflows. The system also provides published interfaces to integrate extensible code that perform custom functions within the system. | 01-03-2013 |

20130310702 | SYSTEMS AND METHODS FOR ACTIVATING TRANSDUCERS - Transducer-based systems and methods may be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Transducer activation characteristics, such as initiation time, activation duration, activation sequence, and energy delivery characteristics, can vary based on numerous factors. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation. | 11-21-2013 |
