Abstract: An augmented reality (AR) output device or virtual reality (VR) output device is worn by a user, and includes one or more sensors positioned to detect actions performed by a user of the immersive output device. A processor provides a data signal configured for the AR or VR output device, causing the immersive output device to provide AR output or VR output via a stereographic display device. The data signal encodes audio-video data. The processor controls a pace of scripted events defined by a narrative in the one of the AR output or the VR output, based on output from the one or more sensors indicating actions performed by a user of the AR or VR output device. The audio-video data may be packaged in a non-transitory computer-readable medium with additional content that is coordinated with the defined narrative and is configured for providing an alternative output, such as 2D video output or the stereoscopic 3D output.

Abstract: A processor provides a simulated three-dimensional (3D) environment for a game or virtual reality (VR) experience, including controlling a characteristic parameter of a 3D object or character based on at least one of: an asynchronous event in a second game, feedback from multiple synchronous users of the VR experience, or on a function driven by one or variables reflecting a current state of at least one of the 3D environment, the game or the VR experience. In another aspect, a sensor coupled to an AR/VR headset detects an eye convergence distance. A processor adjusts a focus distance for a virtual camera that determines rendering of a three-dimensional (3D) object for a display device of the headset, based on at least one of the eye convergence distance or a directed focus of attention for the at least one of the VR content or the AR content.

Abstract: A linear motor activator for a downhole safety valve including a permanent magnet carrier; a plurality of permanent magnets mounted to the permanent magnet carrier; a coil carrier disposed in magnetic field proximity to the permanent magnet carrier; and a plurality of coils mounted to the coil carrier, one of the permanent magnet carrier and the coil carrier being movable relative to the other of the permanent magnet carrier and coil carrier, and being connected to a component of a downhole safety valve and method.

Abstract: An actuator and counterbalance system including a nonmobile carrier; a mobile carrier, mobile relative to the non mobile carrier; and a counterbalance system in operable communication with the mobile carrier and configured to counterbalance less than 100 percent of a return force of a tool actuated by the actuator and method.
