  • Publication number: 20200406905
    Abstract: Systems, methods, and non-transitory computer-readable media can determine sensor data captured by at least one sensor of a vehicle while navigating an environment over a period of time. Information describing one or more agents associated with the environment during the period of time can be determined based at least in part on the captured sensor data. A schema-based encoding describing the environment during the period of time can be generated based at least in part on the determined information and a scenario schema, wherein the schema-based encoding provides a structured representation of the environment during the period of time.

  • Patent number: 10468326
    Abstract: Metamaterial systems capable of exhibiting changes in thermal conductivities in response to an external control or input, as well as methods relating thereto. The metamaterial systems include first and second plates, and a metamaterial core between and thermally coupled to the first and second plates. The metamaterial core comprises a plurality of elements coupled to and contacting each other, with each of the elements being a pseudo-tetrahedron having surfaces that define surface-to-surface contacts with at least one other of the elements. A force is applied to the metamaterial core that increases contact pressures between the elements at the surface-to-surface contacts thereof and thereby increases thermal contact conductivities at the surface-to-surface contacts and increases a thermal conductivity of the metamaterial core.

  • Patent number: 10197385
    Abstract: Apparatus and methods for measuring the proximity between two components using a hardstop, an actuator and an emitter/detector passing light through a passage in the actuator are disclosed. The passage provides attenuation to the light which changes as the gap between the components changes allowing the measurement and control of the gap. Methods of determining the topology of the components using the apparatus are also described.
