  • Patent number: 11953901
    Abstract: An autonomous vehicle includes one or more sensors for detecting an object in an environment surrounding the autonomous vehicle and a vehicle computing system comprising one or more processors receiving canonical route data associated with at least one canonical route, and controlling travel of the autonomous vehicle based on sensor data from the one or more sensors and the canonical route data associated with the at least one canonical route. The at least one canonical route comprises at least one roadway connected with another roadway in a plurality of roadways in a geographic location that satisfies at least one route optimization function derived based on trip data associated with one or more traversals of the plurality of roadways in a geographic location by one or more autonomous vehicles.

  • Patent number: 11067634
    Abstract: A method for estimating a state of charge of a battery includes obtaining a discharge voltage and discharge capacity curve of a battery under a preset discharge current, in responding to an order for estimating the state of charge of the battery; matching the discharge voltage and discharge capacity curve with a plurality of standard curves in a database, thereby obtaining an optimal matching curve with respect to the discharge voltage and discharge capacity curve; and calculating the state of charge of the battery according to the optimal matching curve, under a preset discharge stage. The present method can accurately calculate the state of charge of the battery with simple calculation manners.

  • Patent number: 8883083
    Abstract: The present invention is an air cleaner that uses molecular sieves, such as zeolite or other microporous/nanoporous crystalline materials with pore sizes ranging from 4 ? to 20 ?, as a filter to remove contaminant gas. The contaminants are adsorbed into the porous material along with ions clusters, or any other oxidant generated by a generating device within the system. The contaminant gas is then catalytically decomposed in the confined space of the pore. In one embodiment, transition metal is incorporated into the porous material, and a heater is installed to substitute or accompany the oxidant-generating device. When the heater is turned on, the contaminant is decomposed within the pores of the materials with the transition metals acting as catalysts. Ultimately, the non-harmful byproducts are the small sized water molecutes and carbon dioxide molecules. Growth of bacteria is also suppressed under a clean and dry condition.

  • Publication number: 20070201520
    Abstract: A mid-infrared emitter sub-system includes a heat sink and a diamond thermal diffusion layer connected to the heat sink through a first thermal bonding layer. The first thermal bonding layer has a first melting point. A semiconductor slab portion of a semiconductor laser is connected to the diamond thermal diffusion layer through a second thermal bonding layer. The second thermal bonding layer has a second melting point that is less than the first melting point.
