  • Patent number: 10025882
    Abstract: The disclosure provides a technique for recursively partitioning a 3D model of an object into two or more components such that each component fits within a predefined printing volume. The technique includes determining a set of planar cuts each of which partitions the 3D model into at least two components, evaluating one or more objective functions for each cut in the set of planar cuts, and selecting a cut from the set of planar cuts based on the evaluations of the objective functions. In addition, the technique includes, upon determining that a component resulting from the selected cut does not fit within the predefined printing volume, further partitioning that component.

  • Patent number: 10018996
    Abstract: Roughly described, a manufacturing process is enhanced by using TCAD and TCAD-derived models. A TCAD simulation model of the process is developed, which predicts, in dependence upon a plurality of process input parameters, a value for a performance parameter of a product to be manufactured using the process. Estimated, predicted or desired values for a calculated subset of the parameters (including either process input parameters or product performance parameters or both), are determined in dependence upon the process model, and further in dependence upon actual, estimated or desired values for a different subset of the parameters (again either process input parameters or product performance parameters or both). The determination is preferably made using a process compact model of the process, itself developed in dependence upon the simulation model.

  • Patent number: 9996635
    Abstract: A design method of freeform imaging lens with a wide linear field-of-view (FOV) is provided. A initial freeform imaging lens is developed, and the initial freeform imaging lens includes a first lens surface and an entrance pupil spaced from each other, wherein the FOV of the system 2? (±?) is divided into 2k+1 sampling fields with equal interval ?? between each two adjacent sampling fields. Each two adjacent sampling fields are taken as one group. Two constraints are employed to calculate the plurality of data points of the first lens surface to obtain a front surface of the freeform imaging lens. The data points are calculated based on Snell's law, and a curve is obtained through the data points. A back surface is added to approximately keep the previous outgoing direction of rays from the front surface.

  • Patent number: 9984180
    Abstract: Described herein is an empirical model to estimate inflow performance relationship (IPR) of fishbone wells. A reservoir simulation model is formulated and initial values for a plurality of reservoir and fishbone well parameters are assigned. IPR curves are generated by simulating the formulated reservoir model for a predetermined number of iterations. Each simulation iteration has a unique value of bottom-hole flowing pressure. Sensitivity analysis is performed based on the generated IPR curves by sequentially changing the values of the plurality of fishbone well parameters. Further, regression analysis is performed based on the sensitivity analysis in order to determine an empirical model that estimates the IPR of the fishbone well. The empirical model is determined as a function of a number of multilateral branches of the fishbone well.

    Abstract: Improved finite-difference staggered grid wave propagation systems and methods. One illustrative computer-based wave field simulation method includes: applying at least one signal to a grid of model cells forming a model space, each model cell having stress values associated with stress nodes and velocity values associated with velocity nodes staggered from the stress nodes; and propagating the at least one signal as a wave into the model space by alternately updating the stress values and the velocity values to obtain a time-dependent wave field associated with the at least one signal. The stress value updating includes, for each model cell: determining spatial derivatives of the velocity values for the model cell; interpolating the spatial derivatives to multiple stress nodes within the model cell; and, for each stress node within the model cell, combining the spatial derivatives associated with that stress node to update at least one stress value associated with that stress node.

  • Patent number: 9886526
    Abstract: Errors caused by shrinkage during 3D printing may be minimized. A shape that most closely corresponds to the shape of a layer to be printed may be selected from a library of shapes. Each shape in the library may have shrinkage information associated with it that includes, for each of multiple points that define a perimeter of the library shape, a radial distance to the point from an origin of a coordinate system, an angle the radial distance makes with respect to an axis of the coordinate system, and information indicative of an anticipated amount by which the point will deviate from its specified location when the shape is printed due to shrinkage. Compensation for anticipated shrinkage may be calculated based on the shrinkage information that is associated with the selected shape from the library. The information indicative of the shape of the layer to be printed may be modified to minimize errors cause by shrinkage based on the calculated compensation.
