  • Publication number: 20230066686
    Abstract: Augmented reality (AR) systems, devices, media, and methods are described for generating AR experiences including interactions with virtual or physical prop objects. The AR experiences are generated by capturing images of a scene with a camera system, identifying an object receiving surface and corresponding surface coordinates within the scene, identifying an AR primary object and a prop object (physical or virtual), establishing a logical connection between the AR primary object and the prop object, generating AR overlays including actions associated with the AR primary object responsive to commands received via a user input system that position the AR primary object adjacent the object receiving surface responsive to the primary object coordinates and the surface coordinates within the scene and that position the AR primary object and the prop object with respect to one another in accordance with the logical connection, and presenting the generated AR overlays with a display system.

  • Publication number: 20230060150
    Abstract: Augmented reality (AR) systems, devices, media, and methods are described for sending and receiving AR objects (e.g., customized AR objects) based on/responsive to interactions with the physical world. AR virtual delivery route overlays are generated responsive to selected virtual delivery routes and include the AR object and a delivery mode (air, tunnel, etc.) corresponding to the virtual delivery route. Physical world actions associated with the delivery mode (blowing adjacent an AR device or scratching a surface) result in sending a communication corresponding to the AR object for delivery to a receiver and generating AR sending overlays including the AR object moving in accordance with the delivery mode.

    Abstract: The present disclosure relates to a bone conduction speaker and its compound vibration device. The compound vibration device comprises a vibration conductive plate and a vibration board, the vibration conductive plate is set to be the first torus, where at least two first rods inside it converge to its center; the vibration board is set as the second torus, where at least two second rods inside it converge to its center. The vibration conductive plate is fixed with the vibration board; the first torus is fixed on a magnetic system, and the second torus comprises a fixed voice coil, which is driven by the magnetic system. The bone conduction speaker in the present disclosure and its compound vibration device adopt the fixed vibration conductive plate and vibration board, making the technique simpler with a lower cost; because the two adjustable parts in the compound vibration device can adjust both low frequency and high frequency area, the frequency response obtained is flatter and the sound is broader.

  • Patent number: 11590498
    Abstract: There is provided an arrangement (100) which allows for mixing a first fluid with a second fluid at a predetermined volume mixing ratio in a capillary driven fluidic system. The arrangement (100) allows filling an initially empty mixing chamber (110) with the first fluid. The arrangement then allows emptying a predetermined fraction of the first fluid from the mixing chamber (110) such as to form an empty space in the mixing chamber (110). The arrangement then allows filling the empty space of the mixing chamber (110) with the second fluid, thereby allowing a predetermined volume of the first fluid to mix with a predetermined volume of the second fluid over time.
