  • Patent number: 11127217
    Abstract: A method, system, computer-readable media, and apparatuses for providing a shared vehicle experience between a user located in a remote location and one or more occupants of a vehicle. A device associated with the user receives an exterior video stream corresponding to an exterior environment of the vehicle, along with occupant information comprising location of the one or more occupants in the vehicle. Based on the occupant information, a first augmented video stream is generated. The first augmented video stream comprises one or more dynamic avatars representing each of the occupants of the vehicle, and shows the exterior environment of the vehicle from a perspective of a virtual passenger of the vehicle. The first augmented video stream is displayed to the user to provide the user with an experience of being in the vehicle.

  • Patent number: 11107281
    Abstract: A method, system, computer-readable media, and apparatuses for providing a shared vehicle experience. The method includes capturing an exterior video stream that depicts an exterior environment of a vehicle, and receiving remote user information indicating a bodily movement of a remote user. The method further includes generating and displaying an augmented video stream comprising a dynamic avatar representing the remote user as a virtual passenger, the dynamic avatar being updated based on the remote user information while the augmented video stream is being displayed in the vehicle. At least a portion of the exterior video stream and occupant information are sent to a computer device that causes, based on the at least a portion of the exterior video stream and the occupant information, a display device of the remote user to output an additional augmented video stream that provides the remote user with an experience of being in the vehicle.

  • Patent number: 11085150
    Abstract: The invention provides calendered tissue webs and products produced by passing a tissue web through a calender nip created by a patterned roll having a first pattern and a second pattern thereon and a substantially smooth roll. As the web is transported through the nip it is subjected to variable calender loads that impart variable cross-machine (CD) direction properties to the resulting calendered web. CD properties that may be varied according to the present invention include sheet caliper, sheet bulk and surface smoothness. The variable CD property may be preserved in the web as it is further converted, such as winding about a core, resulting in tissue products having physical properties that vary along at least one dimension of the product.

  • Publication number: 20210140119
    Abstract: The present invention discloses tissue products, specifically rolled paper towel products, such as one, two or three ply tissue products having a basis weight greater than about 35 gsm and a GMT greater than about 1,500 g/3?. The products have a three-dimensional surface, typically the air contacting surface, comprising substantially continuous machine direction (MD) oriented elements, discrete cross-machine direction (CD) oriented elements and discrete MD oriented valleys having valley sidewalls formed by the MD oriented elements and valley endwalls formed by the CD oriented elements. The discrete valleys generally have a length greater than about 10.0 mm. The CD oriented elements comprise a relatively small percentage of the tissue surface area, such as less than about 15 percent, yet the tissue products display good anti-nesting properties when spirally wound into rolls, such as a Roll Structure greater than about 1.75.
