  • Patent number: 10513223
    Abstract: In a door mirror device for a vehicle, an engaging ring that rotates together with a case is provided on an interior floor portion of the case. A restricting ring is provided at the upper side of the engaging ring and is urged toward the lower side by a coil spring. The restricting ring is movable to a side in an axial direction of a support shaft of a stand, but relative rotation of the restricting ring with respect to the support shaft is restricted. Therefore, in a state in which upper side protrusion portions of the engaging ring go out from restricting recess portions of the restricting ring, the restricting ring is moved toward the upper side. Consequently, movement of the case toward the upper side can be suppressed.

  • Patent number: 10451875
    Abstract: A head mounted display (HMD) device is configured with a sensor package that enables head tracking to determine the device user's proximity to virtual objects in a mixed reality or virtual reality environment. A fade volume including concentrically-arranged volumetric shells is placed around the user including a near shell that is closest to the user, and a far shell that is farthest from the user. When a virtual object is beyond the far shell, the HMD device renders the object with full opacity (i.e., with no transparency). As the user moves towards a virtual object and it intersects the far shell, its opacity begins to fade out with increasing transparency to reveal the background behind it. The transparency of the virtual object increases as the object gets closer to the near shell and the object becomes fully transparent when the near shell reaches it so that the background becomes fully visible.
