Fringe-projection autofocus system devoid of a reference mirror. The closed media network access device is configured to receive the media content over the closed media network, provide at least a component of the media content to an output device for presentation to a user, receive audio input including user voice input provided by the user, and utilize the user voice input in at least one of a voice command application and a communication application. Thereafter, a Voronoi region associated with each of the 3D objects is computed, thereby resulting in a complete Euclidean Voronoi diagram of the set of 3D objects. The hard bias layer includes a permanent magnetic layer formed on top of a seed layer made of the alloy TiW or other similar alloys. Methods of using and making the stored-value card are provided. The second driving circuit area is disposed on the display layer.
