  • Patent number: 11454966
    Abstract: Systems and methods provide for routing an autonomous vehicles based on an assessment of its limitations. The autonomous vehicle can avoid problematic routes by applying a set of rules to a map, where the set of rules are associated with a feature that causes a failure of the autonomous vehicle due to an autonomous vehicle limitation. Based on the application of the set of rules, a portion of a route on the map that is associated with the feature can be identified, and an identifier can be applied to the identified portion of the route associated with the feature on a routing map. The portion of the route can be omitted from a routable graph applied to the routing map, such that the route for the autonomous vehicle is generated in accordance with the routable graph.

  • Patent number: 10451247
    Abstract: An optic can manage light emitted by a light emitting diode. The optic can comprise a backside that faces the light emitting diode and a front side opposite the backside. The front side can be convex. The backside can have a central region that is adjacent the light emitting diode and that is either concave or convex. One or more grooves can extend peripherally about the central region. An injection molding system can produce optics in which the backside comprises the concave central region as well as optics in which the backside comprises the convex central region. The molding system can utilize one molding member shaped according to the front side of the optic. That molding member can be compatible with two other molding members that are shaped according to the different backsides of the optic. Thus, two different optic forms can be produced with three molding members.

  • Patent number: 10333036
    Abstract: A method is provided for fabricating an emissive display color conversion film. An emissive substrate top surface is conformally coated with an optically transparent carrier film, covering an array of emissive elements. A suspension, including a fluid and a color conversion material (e.g., QDs), is then selectively deposited in absorption regions overlying the emissive elements, for example, using inkjet patterning. After the suspension is absorbed into the absorption regions, the fluid is removed from the suspension, leaving the color conversion material in the absorption regions, and forming the color conversion film. The removal of the fluid encapsulates the color conversion material in the absorption regions. Typically, the conformal coating is thick enough to form a planar top surface. The conformally coating of carrier film may also act to encapsulate both properly aligned emissive elements, as well as misaligned emissive elements that may be located on the emissive substrate top surface.
