20120191625 | MULTIMEDIA COMMUNICATION AND SUPPORT SYSTEM THAT CAN BE USED WORLDWIDE FOR ASSEMBLY, INSPECTION, MAINTENANCE, AND REPAIR ASSIGNMENTS IN TECHNICAL FACILITIES, AND METHOD - An apparatus for providing a fitter with multimedia support during assembly work in or on a technical facility is provided. Existing remote-controlled systems for supporting technicians on-site do not offer sufficient support possibilities. By means of the apparatus, which includes a competence center having different transmitters and receivers, and a computer on-site, which has a multimedia system for examination, the support is improved and considerably faster. | 07-26-2012 |
20130008180 | METHOD AND APPARATUS FOR DISTRIBUTED CLEFT AND LIBERATED TILE DETECTION ACHIEVING FULL COVERAGE OF THE TURBINE COMBUSTION CHAMBER - A component sensing system for monitoring the condition of ceramic tiles in a combustion chamber of a gas turbine engine. The sensing system includes an optical fiber that is mounted to the component being monitored, for example, the ceramic tiles in the gas turbine combustion chamber. The optical fiber can be formed in any suitable orientation or configuration, such as a meandering or serpentine orientation. The fiber is optically coupled to a Brillouin signal analyzer that provides an optical pulse to the sensing section of the fiber and detects Brillouin backscattering from the fiber as the pulse travels along the fiber. The frequency of the Brillouin backscattering signal is monitored relative to the distance along the sensing section of the fiber. A rise in temperature at a location of the fiber shows up in the analyzer as an increase in frequency of the backscattered signal. | 01-10-2013 |
20130204812 | METHOD FOR COMPUTER-AIDED CLOSED-LOOP AND/OR OPEN-LOOP CONTROL OF A TECHNICAL SYSTEM - A method for computer-aided closed and/or open-loop control of a technical system is provided. A first value of an output quantity is predicted on a data-based model at a current point in time. A second value of the output quantity is determined from an analytical model. The state of the technical system at the current point is assigned a confidence score in the correctness of prediction of the data-based model. A third value of the output quantity is determined from the first and second value as a function of the confidence score for controlling the technical system. A suitable value for the output quantity can be derived from the analytical model even for regions of the technical system in which the quality of prediction of the data-based model is low because of a small set of training data. The technical systems can be turbines, such as gas turbines. | 08-08-2013 |

20140324739 | SYSTEMS AND METHODS FOR LEARNING OF NORMAL SENSOR SIGNATURES, CONDITION MONITORING AND DIAGNOSIS - Systems and methods to monitor a signal from an apparatus are disclosed. A feature extracted from the signal is automatically defined. Signals are received over a period of time wherein the apparatus is in a normal operational mode. Features are classified in a learning mode and are applied to create a reference model that defines a within-normal operational mode. In a testing mode a signal generated by the apparatus is received, a feature is extracted and classified. Instantaneous data generated in operational mode by the apparatus is classified by the system as abnormal if it does not lie within boundaries of the reference model or contains information/structure in an orthogonal subspace. A learned reference model is augmented by a user or automatically. In one illustrative example the apparatus is a power generation equipment and the signal is an acoustic signal. | 10-30-2014 |
20140358865 | PROCESSING A TECHNICAL SYSTEM - Rules of a rule base are transformed in an automated fashion in order to be able to conduct consistency checks and generate explanations and thus classify and correct existing rules. This is beneficial in particular in large systems with existing rule bases, e.g., wherein each rule is associated with at least a diagnostic task of a component of a technical system, e.g., a power system. The task can be subject to fault detection, fault isolation, predictive diagnosis or reporting. The solution presented provides an overview of large sets of rules and thus allows determining which rules are suitable and which are not. The invention is applicable for all kinds of technical systems, e.g., industry and automation systems, in particular power systems. | 12-04-2014 |

A confidence measurement (C(t)) is determined for respective input variables (x(t)), using one or more density estimators (DE), this measurement being higher, the greater the similarity of the input variables (x(t)) to known input variables from training data with which the data-driven model (NN) and the density estimator (DE) are taught. Based thereon, an average weighted deviation (E(t)) is determined between the prognosticated output variables (y(t)) and the output variables (y | 08-27-2015 |
