  • AUGMENTED REALITY CAMERA FRUSTUM
    Publication number: 20180157047
    Abstract: An apparatus such as a head-mounted display (HMD) may have a camera for capturing a visual scene for presentation via the HMD. A user of the apparatus may be operating a second, physical camera for capturing video or still images within the visual scene. The HMD may generate an augmented reality (AR) experience by presenting an AR view frustum representative of the actual view frustum of the physical camera. The field of view of the user viewing the captured visual scene via the AR experience is generally larger that the AR view frustum, allowing the user to avoid unnatural tracking movements and/or hunting for subjects.

  • Seatless wet cylinder liner for internal combustion engine
    Patent number: 8978620
    Abstract: An apparatus includes an internal combustion engine with an engine block and a cylinder liner housing a piston. The engine block includes at least one cylinder cavity and at least one replaceable cylinder liner positioned within the cylinder cavity. At least two press fit areas create an interference fit between the engine block and the replaceable cylinder liner. One press fit area is located proximate to the top surface of the engine block and the other press fit area is located in the engine block at the opposite end of the cylinder liner. A storage volume is formed between the press fit areas by the outer surface of the cylinder liner and the surface of the engine block defining the cylinder cavity.
