Abstract: A method of designing hearing aid molds is disclosed whereby two shapes corresponding to graphical images of ear impressions are registered with each other to facilitate joint processing of the hearing aid design. In a first embodiment, a first graphical representation of a first ear impression is received and a feature, such as the aperture of the ear impression, is identified on that graphical model. A first vector is generated that represents the orientation and shape of that first feature. The three-dimensional translation and rotation of that first vector are determined that are necessary to align the first vector with a second vector representing the orientation and a shape of a feature, once again such as the aperture, of a second ear impression. In another embodiment, this alignment is then refined by minimizing the sum of the distances between points on the first and second graphical representations.

Abstract: Related communication signals between a simulator and an emulator are organized into logical channels. The signals in each channel are then be transmitted only as needed, reducing the use of the communication pathways between the simulator and the emulator. Further, the circuit components that will receive the communication signals to be shared on a channel are be physically located close together within the emulator, thereby reducing the time required to select and enable components of the emulator to receive the signals sent by the simulator. Similarly, emulator components that send communication signals to be shared on a channel are physically located close together within the emulator, thereby reducing the time required to select and enable components of the emulator to send these signals to the simulator.

Abstract: A method for analyzing an oilfield network. The method includes collecting oilfield data from an oilfield network, modeling a first wellsite and a second wellsite using the oilfield data to create a first production model of the first wellsite and a second production model of the second wellsite. The method further includes modeling a sub-network of the oilfield network to create a third production model of the sub-network. The modeling of the sub-network includes identifying a junction of branches associated with the first wellsite and the second wellsite. A fourth production model is created for the junction by combining the first production model with the second production model. The production model of the sub-network is created using the fourth production model of the junction. The method further includes solving the oilfield network based on the third production model to create a production result, and storing the production result.

Abstract: Multiple models for various stages of a non-linear process control are developed by clustering perturbation data obtained from the nonlinear process so as to permit multiple local data regions to be identified as a function of substantial similarity between the data, wherein the data of first data set represent the non-linear process. A discrete model corresponding to each of the local data regions is generated. The number of the discrete models may be reduced as a function of prediction error between actual outputs of the process and predicted outputs of the models and as a function of a gap metric based on closed loop similarity and frequency response similarity between the models.

Abstract: A method and apparatus is disclosed whereby a point on an ear impression model to be labeled is selected and a shape context is determined for that point. This shape context is then compared to average shape contexts for different regions on a reference ear impression model, also referred to herein as an ear impression shape atlas. A cost function is used to determine the minimum cost between the shape context for the selected point and one of the average shape contexts. Once the minimized cost is determined, the region label corresponding to the average shape context having a minimized cost is assigned to that point. In this way, points on the surface of an ear impression are classified and labeled as being located in regions corresponding to the regions on the ear impression shape atlas.

Abstract: Clock gating analysis of a target circuit having a plurality of clock gates, involves the calculation of a clock gate function for each of the clock gates. The clock gate functions indicate an activation state of the clock gates and a combination of output values from sequential circuit elements in the target circuit are substituted into each of the clock gate functions to obtained clock gate function values. Combinations of the clock gate function values form individual clock gating states. Each clock gating state indicates an activation state of each of the local clocks, collectively. A table indicating correlations between the combinations of output values and the clock gating states is generated and from the conversion table, a group that includes all of the clock gating states possible is output.

Abstract: In one aspect of the invention, each bolt is modeled using a beam element in a FEA model. To apply desired pretension to one or more bolts, at least one pretension-versus-time curve is specified. Each pretension-versus-time curve includes ramp portion, desired pretension portion and optional unloading portion. Duration of the pretension-versus-time curve generally covers first 0.5-1% of total simulation time of a car crashworthiness analysis. Ramp portion starts from zero to desired pretension in a substantially linear manner, and hence being configured for applying desired pretension to a bolt gradually with smaller increments. Desired pretension portion is configured for ensuring the desired pretension can actually be applied to the beam element during an initialization process—a series of quasi-static analyses. Since the method is independent of the deformation of the beam, the method completely avoids the need to iteratively determine an axial strain or displacement that gives the desired pretension.

Abstract: The invention is a method of testing a storage network that includes a method of handling data at the port and bus level. The method includes emulating targets in computer memory, receiving data from initiators, and passing to computer memory only a portion of the data received.

Abstract: A method of providing simulation results includes detecting any power net and rail in a circuit netlist. The circuit can be divided into net-partitioned blocks. Using these net-partitioned blocks, a topological analysis can be performed to identify cuttable/un-cuttable devices and synchronization requirements. Then, the circuit can be re-divided into rail-partitioned blocks. Using these rail-partitioned blocks, a sparse solver can identify potential partitions, but eliminate fill-ins as determined by the topological analysis. A cost function can be applied to the potential partitions as well as the identified cuttable/un-cuttable devices to determine final cut points in the circuit and dynamic inputs to the final blocks. Simulation can be performed on the final blocks and simulation results can be generated.

Abstract: Processor emulation using fragment level translation is disclosed. A target system having a main target processor, a secondary target processor element and an instruction memory associated with the secondary target processor element may be emulated with a host system having one or more host processors and a host memory. Two or more target system code instructions for the secondary target processor may be grouped into one or more fragments with known starts and ends. A data structure that maps the host memory locations of the starts and ends may be maintained. Each fragment may be translated into a corresponding set of position-independent translated fragments executable by the host system. The translated fragments may be loaded into one or more of the host processors. If a memory layout for target system code corresponding to the one or more fragments has changed, the fragments may be dynamically re-linked, without re-translation, and executed.

Abstract: This invention presents a method of novel nonlinear control for designing Static Synchronous Compensators (STATCOM). A passivity-based approach is proposed for designing robust nonlinear STATCOM controller. The mathematical model of STATCOM will be represented by an Euler-Lagrange (EL) system corresponding to a set of EL parameters. By employing the Park's transformation, the differential geometry approach is used to investigate the power system dynamics with considering STATCOM under the synchronous d-q frame. The energy-dissipative properties of the proposed model derived in the synchronous d-q rotating frame are fully retained. This model also consider the dynamic response of the changable load. Finally, the passivity-based control is employed by using energy shaping and damping injection techniques to produce the proper control signals for Voltage Source Converter. So that the system embedded with STATCOM is more robust and stable.
