  • Patent number: 10578947
    Abstract: A media-defined optical logic circuit composed of a set of light-transmitting polyhedral prisms arranged so that a pair of adjacent prisms can exchange photonic signals through adjacent surfaces. Each prism contains one or more quantum dots that, when excited by a photonic signal received from an adjacent prism, respond by emitting light that becomes an incoming photonic signal for an adjacent prism. Photonic signals are propagated through the circuit in this manner along light-guide paths created by shading certain surfaces to render them fully or partially opaque. The prisms and shading are arranged such that the circuit performs a certain logic function. When the circuit receives a set of photonic input signals representing a binary input value, the circuit responds by emitting a set of photonic output signals that represent a binary output value determined by performing the logic function upon the binary input value.

  • Patent number: 10545456
    Abstract: A machine is configured to perform hologram location within a scene to be generated. The machine accesses target motion data that describes movement of a target device. Based on the target motion data, the machine determines a target motion vector that indicates a target speed of the target device and indicates a target direction in which the target device is moving. The machine determines a hologram motion vector for a hologram to be generated for display by a user device. The hologram motion vector indicates a relative speed of the hologram and indicates a relative direction of movement for the hologram. The machine then causes the user device to generate a scene in which the hologram moves at a speed determined based on the target speed and on the relative speed, as well as moves in a direction determined based on the target direction and on the relative direction.
