  • Patent number: 8831255
    Abstract: An augmented reality (AR) audio system for augmenting environment or ambient sound with sounds from a virtual speaker or sound source positioned at a location in the space surrounding an AR participant. The sound from the virtual speaker may be triggered by an action of the listener and/or by the location or relative orientation of the listener. The AR audio system includes stereo earphones receiving an augmented audio track from a control unit, and binaural microphones are provided to capture ambient sounds. The control unit operates to process trigger signals and retrieve one or more augmentation sounds. The control unit uses an AR audio mixer to combine the ambient sound from the microphones with the augmentation sounds to generate left and right ear augmented audio or binaural audio, which may be modified for acoustic effects of the environment including virtual objects in the environment or virtual characteristics of real objects.

  • Patent number: 8591346
    Abstract: A rotating hub ride configured to position passenger vehicles at different vehicle radii relative to the hub's axis of rotation. The ride includes curved support arms extending outward from the hub, with a first end coupled to the hub at a lower height than a second end of the arm. A vehicle is attached, via a mounting assembly, to each curved support arm to slide radially inward and outward on the arm in response to forces applied to the vehicle due to rotation of the hub, e.g., at two or more hub rotation rates. The arm or track defines a travel path for radial movement of the vehicle. When hub rotation is halted, the vehicle slides inward on the track to a load position corresponding to a minimum vehicle radius. At increasing hub speeds, the vehicle slides outward to position the vehicle in any of a number of vehicle radii.
