20110147267RAPID CYCLE REFORMING PROCESS - This invention relates to process for producing a reformate or gasoline product. The process involves a rapid cycle of reacting hydrocarbon feedstock to form the product and then regenerating the catalyst used in the reaction. The process can be carried out at relatively high liquid hourly space velocities and preferably at relatively low hydrogen to hydrocarbon ratios to produce a reformed product having relatively high liquid yield and hydrogen content.06-23-2011

20080208661METHOD AND SYSTEM OF USING ANRTIFACTS TO IDENTIFY ELEMENTS OF A COMPONENT BUSINESS MODEL - A method and system are described for using business artifacts to identify elements of a component business model. Artifacts operated upon by the business are first identified, and then used to analyze the business into business operations. This is done by identifying every business activity that acts on an artifact, creating directed graphs for the business activities, and decomposing the directed graphs into sub-graphs, each sub-graph representing a business operation and being annotated by a verb expression, the annotated sub-graph representing a business service. The business services are then clustered into non-overlapping components, using common affinities reflected in the verb expressions, and organized by partitioning into internal and external operations, exposing a business service for each external operation. The components are then clustered into non-overlapping business competencies, and arranged by accountability level.08-28-2008
20080215397SYSTEM AND MECHANISM TO CREATE AUTONOMIC BUSINESS SOLUTIONS - Automomic business processes management solutions have capabilities to adapt themselves to changes in the business environment. These autonomic business solutions are built by wiring together autonomic solution components called BPbots (Business Process robots). BPbots are granular solution components representing an aspect of a business process. In general, BPbots consist of two parts, an execution module and a managerial module. The execution module represents the standard, non-autonomic solution component, such as a standard process flow model describing the long-running flow or business adapter describing the communication of the solution with service providers (such as applications). The managerial module is responsible for the autonomic behavior of the BPbot. The managerial component has the ability to monitor the execution module, analyze the performance, plan new, more appropriate execution patterns and change the behavior of the execution module according to the new plan.09-04-2008
20080270201METHOD AND SYSTEM FOR MODELING SERVICES IN A SERVICE-ORIENTED BUSINESS - A method of modeling a service-oriented business including identifying a business service to provide, creating its business specification which specifies business requirements for the provided service, the business specification of a service, and service management terms, storing the business specification for the provided service in a service catalog, creating and reviewing its business process model, the business process model providing a sequence of business tasks in the business process, analyzing each of the business tasks to determine which of the business tasks should be accomplished via required service, process modeling each of the business tasks that are not service tasks, storing a process model for each of the business tasks that are not service tasks in a operation model repository, creating a business specification for each required service and storing the business specification for each of the required services in a repository of business specifications of required services.10-30-2008
20090319981SYSTEM AND METHOD FOR GENERATING IMPLEMENTATION ARTIFACTS FOR CONTEXTUALLY-AWARE BUSINESS APPLICATIONS - A method for generating implementation artifacts for contextually-aware business applications includes utilizing a platform independent model (PIM) of a business application; generating a platform specific model (PSM) from the PIM, wherein the generating of a PSM includes one or more transformations between one or more meta-models of the PIM and one or more meta-models of the generated PSM; generating implementation artifacts; and binding the generated implementation artifacts with any existing services of the business application.12-24-2009

20100007144VERTICAL AXIS WIND SYSTEM - A vertical axis wind system for use in electrical power generation. The system includes a stationary base including a generator and has an elongate shaft rotatably coupled the base. The elongate shaft extends vertically from a lower end to an upper end along a vertical central axis and engages the generator. At least two arcuate blade assemblies are attached between the lower end and the upper end of the elongate shaft such that aerodynamic forces acting on the at least two arcuate blade assemblies rotate the elongate shaft for the generation of power.01-14-2010

20100099996DEVICE, METHOD AND COMPUTER-READABLE STORAGE MEDIUM FOR DETECTING AND CLASSIFYING OF CARDIAC EVENTS - Method for detecting cardiac events, e.g., Atrial Fibrillation (AF) or termination of AF. Based on analysis of the instability observed in heart rate, caused by irregular conduction from the atrium during AF. Change in heart interval is monitored on beat-to-beat basis to recognize instability that indicates presence of AF or Atrial Flutter. A packet of a number of consecutive intervals is evaluated, whether the length of an interval is stable compared with the length of the preceding interval, or whether the length of the subsequent interval has changed. After detection of an instability, instability counter is incremented. The result of the stability test for a packet of intervals is represented by the value of the instability counter. Depending upon whether or not an AF already declared, (indicated by AF status flag), different “X-out-of-Y” criterion are applied. AF status flag set/cleared when declaring AF/termination of AF.04-22-2010
20100100143DEVICE, METHOD AND COMPUTER-READABLE STORAGE MEDIUM FOR CLASSIFYING ATRIAL TACHYARRHYTHMIA - Device for classifying tachyarrhythmia that obtains pre-defined values, monitors atrial intervals and compares lengths of each interval with pre-defined value IL, stores length of atrial interval if length is shorter than IL, in case X of most recent Y number of atrial intervals have length shorter than IL, evaluates most recent <=N atrial intervals with length=1 criteria, and controls a cardiac device depending on the classification. Atrial intervals are first evaluated by using the “X-out-of-Y” criterion and subsequently checked for stability after an atrial tachyarrhythmia is detected using “X-out-of-Y” criterion. For stability check, only intervals found shorter than the interval limit are used. Check is based on interval-to-interval comparison rather than as generally practiced, comparisons of individual intervals with the minimum or average of all intervals.04-22-2010
20110125043Device, Method, and Computer-Readable Storage Medium for Detecting Events in Cardiac Signals - The present disclosure generally relates to a method, a device, and a computer-readable storage medium for detecting heart beats from cardiac signals whose quality, expressed in terms of signal amplitude and signal-to-noise ratio, varies dynamically in time.05-26-2011

20090094175INTRUSIVE SOFTWARE MANAGEMENT - Intrusion features of a landing page associated with sponsored content are identified. A feature score for the landing page based on the identified intrusion features is generated, and if the feature score for the landing page exceeds a feature threshold, the landing page is classified as a candidate landing page. A sponsor account associated with the candidate landing page can be suspended, or sponsored content associated with the candidate landing page can be suspended.04-09-2009
20090094697INTRUSIVE SOFTWARE MANAGEMENT - Landing pages associated with advertisements are partitioned into training landing pages and testing landing pages. Iterative training and testing of a classification mode on intrusion features of the partitioned landing pages is conducted until the occurrence of a cessation event. Feature weights are derived from the iterative training and testing, and are associated with the intrusion features. The associated feature weights and intrusion features can be used to classify other landing pages.04-09-2009
