摘要:
The invention provides an apparatus and methods for performing process simulation and structural analysis using a hybrid model. For example, a method of the invention automatically defines a hybrid solution domain by dividing a representation of a plastic component or mold cavity into two portions—a portion in which a simplified analysis may be conducted, and a portion in which a more complex analysis is required. The method may use as input any form of CAD data that describes the surface of a component or mold. Furthermore, the invention provides methods for simulating fluid flow within a mold cavity by automatically creating a hybrid solution domain, automatically discretizing the domain, and solving for the distribution of process variables within the solution domain.

A computer implemented method for a touchscreen display is disclosed. The method includes presenting graphical information on the touchscreen display. The method further includes detecting a touch over the touchscreen display. The method also includes expanding an area of the touch screen display proximate the location of the touch.
摘要:
Reaction-bonded silicon carbide artefacts are produced by siliconizing a green body formed from a coherent mixture of silicon carbide and carbon powders. The surface of the green body is coated with a paste comprising silicon powder suspended in a carbonizable viscous medium which, on heating of the coating, is converted to an open cellular carbon structure and then, on siliconizing the green body, to a silicon carbide skeleton through which molten silicon is drawn.
摘要:
A reaction-sintered silicon carbide body having portions differing from each other in free silicon content and such a body with a surface layer rendered more readily abradable than the remainder of the body by the removal of free silicon from the surface layer. It has a particular application in the provision of shrouds for gas turbines, which can be produced by slip-casting in two stages.

The present invention broadly comprises a stator and clutch assembly in a torque converter. The stator has a segment radially disposed between stator blades and a stator axis. The one-way clutch has a plate connected to a hub. The segment forms a portion of the clutch and the stator is axially displaceable to control operation of the clutch. A displacement element urges the stator in a first axial direction. The stator is arranged to move in a second axial direction, opposite the first axial direction, in response to pressure from fluid in the torque converter. In some aspects, the displacement element is selected from the group consisting of a coil spring and a wave spring. In some aspects, the one-way clutch is arranged to disengage when the stator is sufficiently displaced in the first direction and to engage when the stator is sufficiently displaced in the second direction.

A system and method for recognizing a signet and for performing an action associated with the signet. In one embodiment, the method includes generating a touch signal with a signet, the touch signal representing a particular signet pattern, recognizing the particular signet pattern, and performing an action associated with the particular signet pattern.
摘要:
A method for using speech analysis to detect speech pathologies can begin with registration of a patient with a speech-based health monitor. A speech segment baseline representing an initial state of the patient's speech system can be established for the patient. When prompted, the patient can submit a speech segment representing a current state of the patient's speech system to the speech-based health monitor. The speech-based health monitor can analyze the submitted speech segment using the established speech segment baseline and/or a speech segment history that comprises speech segments previously submitted by the patient. Based upon said analysis, satisfaction of a health alert definition can be determined. A health alert definition can define an action performed by the speech-based health monitor when its associated triggering conditions are satisfied. The action associated with the at least one satisfied health alert definition can then be executed.
摘要:
A system for generating video images and corresponding audio of multiple parties engaged in a video conference is provided. The system includes multiple voice transducers for receiving voice signals from the multiple parties and a video camera for capturing moving images of one of the multiple parties who is speaking. The system further includes a processor in communication with the voice transducers and video camera. The processor determines respective distances and angles between the party who is speaking and each of the multiple voice transducers. Additionally, the processor identifies a location of the party who is speaking relative to the video camera based on the determined respective distances and angles. Based on the identified location, the processor selects a portion of a video frame produced by video camera and processes the selected portion to mitigate optical distortion and generate an overall picture in which the party speaking does not appear unnaturally small relative to the overall picture.
