Abstract: A media server machine may be configured to provide media content within a datastream. This datastream may be provided to a media device that is configured to present the media content on a display. Also, this datastream may contemporaneously contain an “app-sync indicator” for the media content. The app-sync indicator is a data structure that signals the media device to launch an application on a companion device. By providing the app-sync indicator contemporaneously with the media content in the datastream, the launching of the application on the companion device may be synchronized with the media content. The app-sync indicator may specify the application to be launched. Also, the app-sync indicator may specify supplemental content to be presented by the launched application on the companion device.

Abstract: A discrete geometrical pattern library guides a method for design optimization of a finite element model in a computer aided design (CAD) environment. Boundary conditions are applied to the finite element model, design variables for the bounded finite element model are initialized, and an objective function for the finite element model is evaluated. A gradient of the objective function is evaluated with respect to the design variables, an appearance constraint function is evaluated for the finite element model, and a gradient of the appearance constraint function is evaluated with respect to the design variables. The design variables are updated using a mathematical programming, and a convergence in the design optimization is detected, producing a converged design optimization of the finite element model is produced.
