Abstract: A high-definition map building method includes determining a key node describing information about a key position of a lane attribute change, determining a key node layer based on a position of the key node and an attribute of the key node, and determining a high-definition map based on a navigation map and the key node layer. The navigation map provides road-level navigation information, and the high-definition map provides lane-level navigation information.

Abstract: A pretreatment solution and process for pretreating steel substrates with an aqueous solution to form a thin partially crosslinked layer that passivates the steel surface and inhibits the formation of flash rust, in which the thin partially crosslinked layer is dried in ambient air, and the dried layer enhances the cathodic disbondment resistance of the overlying paint system. In the process an aqueous precursor solution (A) containing at least one amino-functional silane, at least one of a dissolved silicate or a dissolved aluminate and at least a metal salt; is mixed with an aqueous precursor solution (B) containing at least an epoxy resin. The molar amount of amino-functional silane in precursor solution (A) is at considerably lower than the stoichiometric amount that is needed for completing the crosslinking reaction with the epoxy resin in precursor solution (B) so that unreacted epoxy groups are made available for further crosslinking with the overlying paint.

Abstract: A durable hydrophobic coating composition containing fluorinated silanes for metallic surfaces, such as stainless steel surfaces. The composition includes at least one fluorine-containing silane compound, at least one phosphorus-containing silane compound, and at least one hydrolysable compound. This coating is suitable for condenser tubes, among other applications, to promote dropwise condensation.

These coatings can also be used on metallic substrates for improving their hardness and anti-corrosion (or barrier) properties. The coating composition includes at least one silane which has at least one non-hydrolyzable radical containing an epoxy group, at least one aluminum alkoxide, at least one hydrolyzable silicon compound, at least one acid, and water. The coating composition is a molecular composite formulation and is free from particulate materials.

The coating composition comprises the reaction products of at least one fluorine-containing silane compound (A), at least one hydrolysable compound (B), at least one polysiloxane compound (C), at least one relatively large-sized ceramic particle (I), at least one nano-sized ceramic particle (II) and at least one solvent.

Abstract: A non-chromate conversion coating for copper or other alloys. The conversion coating is composed of hydrotalcite-like compound (HTlcs). The conversion coating adheres well with the alloys, and provides excellent corrosion protection. In addition, corrosion inhibitive species were incorporated into the coating. The coating with inhibitors incorporated showed damage-responsive properties. The corrosion protection property of the conversion coating was further enhanced through applying a surface sealer. The coating has applicability in industrial heat exchangers that use reclaimed water.

The composite component is adapted for use in the power transmission industry and includes a fiberglass inner core, a pliable first coating layer applied to the fiberglass core, and a hard second coating layer applied to the first coating layer.

Abstract: A layered body (1) is provided in which a first layer (3) is deposited at one side on at least one surface of a resin substrate (2), a second layer (4) is deposited on the other side of the first layer (3) opposite to the one side thereof at which the first layer (3) is deposited on the resin substrate (2), the first layer (3) is a first organic-inorganic hybrid layer containing a (meth)acrylic resin and a silane compound, and the second layer (4) is a second organic-inorganic hybrid layer obtained by curing a composition made of a solution obtained by hydrolysis and condensation using a composition which contains a silane compound (A) containing at least one epoxy group and represented by the following Formula (1), an aluminum alkoxide (B) represented by the following Formula (2) and a tetrafunctional silane compound (C) represented by the following Formula (3): Si(R1)p(OR2)4-p??Formula (1); Al(OR3)3??Formula (2); and Si(OR4)4??Formula (3).

Abstract: The invention provides a method and apparatus for establishing and facilitating an audio conference over a network. The method transmits a notice information including a linking application to each of participant stations. Then, the method, based on the linking applications, links the participant stations and the chairman station to a site over the network to conduct the audio conference. Thereby, after receiving the notice information, the participants only have to execute the linking applications to automatically link to the site to participate in the audio conference as the audio conference begins.
