  • Publication number: 20240102818
    Abstract: In some implementations, a computing device can proactively determine a destination and request traffic information for routes from a starting location to the destination. In some implementations, a computing device can identify some routes between a starting location and a destination as non-recommended routes and recommend other routes. In some implementations, a computing device can rank routes between a starting location and a destination based on automatically-determined user interest. In some implementations, a computing device can determine a user is familiar with a route and adjust the information presented to the user about the route accordingly.

  • Patent number: 10214796
    Abstract: Methods for recovering gold from gold-bearing materials are provided. The methods rely upon on the self-assembly of KAuBr4 and ?-cyclodextrin (?-CD) in aqueous solution to form a co-precipitate, a 1:2 complex, KAuBr4•(?-CD)2 (“?•Br”), either alone or in an extended {[K(OH2)6][AuBr4]?(?-CD)2}n chain superstructure (FIG. 1). The co-precipitation of ?•Br is selective for gold, even in the presence of other metals, including other square-planar noble metals. The method enables one to isolate gold from gold-bearing materials from diverse sources, as further described.
