Abstract: Methods and apparatus for implementing a playback system capable of operating as a virtual or augmented reality device are described. In various embodiment one or more environmental triggers are detected and an action is taken based on the detected trigger, user input and/or other environmental conditions. The methods allow a user who is subject to an immersive experience to smoothly transition in/or out of the virtual environment and respond to environmental triggers which may require a user to take an action.

Abstract: A method for gaming, including receiving from a client device of a user selection of a video recording of game play of a player for a gaming application, and streaming the video recording to the client device. The video recording is associated with a snapshot captured at a first point in the recorded game play. Selection of a jump point in the recorded game play is received from the client device. An instance of the gaming application is initiated based on the snapshot to initiate a jump game play. Input commands used to direct the game play and associated with the snapshot are accessed. Image frames are generated based on the input commands for rendering at the client device, the image frames replaying the game play to the jump point. Input commands from the client device are handled beginning from the jump point for the jump game play.

Abstract: A method includes forming an ion-implanted capping layer in a first epitaxial layer disposed on a silicon substrate. The ion-implanted capping layer is doped with a second dopant of a same conductivity type as a first dopant in the silicon substrate. The second dopant has a lower diffusivity than the diffusivity of the first dopant. The ion-implanted capping layer has a thickness configured to contain up-diffusion of the first dopant from the silicon wafer in the first epitaxial layer in thermal processes for fabricating a vertical MOSFET device in the substrate. The ion-implanted capping layer is configured to limit up-diffusion of the first dopant from the silicon wafer through the ion-implanted capping layer into a second epitaxial layer such that a concentration of the first dopant in the second epitaxial layer is lower than a concentration of the first dopant in the first epitaxial layer.
