Patent number: 8932361Abstract: An apparatus and modeling method of the present invention includes the successive steps of generating cartographic data representative of points belonging to a glenoid surface; distinguishing from among the cartographic data a first group of cartographic data corresponding to a first part of the glenoid surface, the first surface part being situated farthest down in the vertical direction in relation to the scapula; calculating from the first group of cartographic data a first ellipsoid portion that coincides substantially with the first surface part; and obtaining a theoretical glenoid surface from the first ellipsoid portion. By virtue of the theoretical glenoid surface obtained by this method, it is possible to assist the surgeon in optimizing the position of implantation of a glenoid component and to produce a glenoid component “made to measure” for the scapula that is to be fitted with a prosthesis.Type: GrantFiled: June 22, 2009Date of Patent: January 13, 2015Assignee: Tornier SASInventors: Alain Tornier, Delphine Henry

Patent number: 8935138Abstract: A method simulates a machining of a workpiece by a tool. The method populates a swept volume representing a motion of the tool in relation to the workpiece with a set of rays, and determines a volume removed from the workpiece by the swept volume based on intersections of at least some rays with the workpiece. A model of the workpiece is modified based on the removed volume.Type: GrantFiled: March 28, 2012Date of Patent: January 13, 2015Assignee: Mitsubishi Electric Research Laboratories, Inc.Inventors: Huseyin Erdim, Alan Sullivan

Patent number: 8924190Abstract: A method including digitally modelling a temperature measured by a sensor by using a modeled signal and estimating a lag error signal for the sensor from the modeled signal and a signal obtained by filtering the modeled signal, the filter having as a parameter an estimate of a time constant of the sensor, and correcting the measurement signal delivered by the sensor by the estimated lag error signal. The time constant of the sensor is estimated as a function of time from the measurement signal and the modeled signal.Type: GrantFiled: December 8, 2009Date of Patent: December 30, 2014Assignee: SnecmaInventor: Cedrik Djelassi

Patent number: 8914265Abstract: Numerical gas turbine models permit transient modeling with high precision and at the same time numerically efficient processes for modeling a gas turbine. A gas turbine model includes a plurality of sub models. These sub models are either purely dynamic or static, which allows significant simplifications in the numerical solution of the overall model. System parts, which simulate the effects of volumes, metal masses, of actuators, and of measuring systems are regarded as dynamic. The remaining system parts are regarded as static over a time characteristic.Type: GrantFiled: April 6, 2011Date of Patent: December 16, 2014Assignee: Alstom Technology LtdInventors: Xiao-Yi Zhang, Anton Nemet

Publication number: 20140365190Abstract: Among other things, one or more techniques and/or systems are provided for facilitating development, by a user, of a model describing a condition of an industrial asset. An output parameter of the model can be defined within a model development environment. The output parameter describes a condition of the industrial asset and can be defined using one or more variables. During deployment of the model within a deployment environment, respective variables of the model can be mapped to a data store where data associated with the variable is located. In this way, during development, a user can specify variables to be used within the model without specifying where to fetch and/or push data associated with the variable, for example. Further, the model can be executed within the deployment environment to assess the condition for a plurality of industrial assets.Type: ApplicationFiled: June 10, 2013Publication date: December 11, 2014Inventors: Shakeel M.

Patent number: 8909507Abstract: Predicted environment conditions are received for time steps within a prediction horizon N. Information is accessed regarding expected system responses generated by a system model, each expected system response related to a different combination of control parameters and starting environment conditions applied to the model. An optimal response is designated for each combination of starting environment conditions for each time step from time step N?1 to the current time step based in part on the expected system response and the predicted environment conditions, each optimal response in a time step based at least in part on an optimal response determined for a later time step. For the current time step, for starting environment conditions substantially similar to the current environment conditions, the combination of control parameters that results in the system response designated as the optimal response is determined from the expected system responses and is applied to the system.Type: GrantFiled: January 31, 2011Date of Patent: December 9, 2014Assignee: Eaton CorporationInventors: Vasilios Tsourapas, Chinmaya B.
