  • Patent number: 12165505
    Abstract: An information providing system includes: first servers in which each first server including a first processor with hardware is provided for each of a plurality of bases. The first processor is configured to calculate a traffic frequency of a vehicle on a road link included in a road map based on past travel data of the vehicle, partition the road map into a plurality of areas so that a total of the traffic frequency in a road link straddling each partitioned area becomes minimum, allocate each base to each of the partitioned areas, and output predetermined information to the vehicle traveling in the partitioned area to which the base is allocated.

  • Patent number: 11800413
    Abstract: An information processing system includes: a first server associated with a first region, the first server including a first processor configured to output information concerning a predetermined service to a vehicle traveling in the first region; and the vehicle including a second processor, wherein the first processor is configured to perform handover processing for outputting information concerning the vehicle held by the first server to a second server associated with a second region adjacent to the first region when the vehicle moves from the first region to the second region in a case where the vehicle has moved to an outside of the first region and to an outside of an extended region obtained by extending the first region.

  • Patent number: 11731078
    Abstract: A desulfurization gas process includes water vapor, CO2 and SOx (x=2 and/or 3). In a treatment unit, the gas contacts a cooled alkaline aqueous solution having a temperature lower than an initial gas temperature, water and a carbonate of an alkali metal, to cool the gas, condense some water vapor and absorb SOx in the carbonate-containing solution, produce an SOx-depleted gas and an acidic aqueous solution including sulfate and/or sulfite ions. The SOx-depleted gas and a portion of the acidic aqueous solution can then be withdrawn from the treatment unit. Carbonate of the alkali metal can be added to remaining acidic aqueous solution to obtain a made-up alkaline aqueous solution. This solution can be cooled and reused as the cooled alkaline aqueous solution. An SOx absorbent solution includes a bleed stream from a CO2-capture process, sodium or potassium carbonate, and an acidic aqueous solution obtained from desulfurization.

  • Patent number: 8784639
    Abstract: An electrochemical process for the concurrent recovery of iron metal and chlorine gas from an iron-rich metal chloride solution, comprising electrolysing the iron-rich metal chloride solution in an electrolyser comprising a cathodic compartment equipped with a cathode having a hydrogen overpotential higher than that of iron and containing a catholyte having a pH below about 2, an anodic compartment equipped with an anode and containing an anolyte, and a separator allowing for anion passage, the electrolysing step comprising circulating the iron-rich metal chloride solution in a non-anodic compartment of the electrolyser, thereby causing iron to be electrodeposited at the cathode and chlorine gas to evolve at the anode, and leaving an iron-depleted solution, which is recirculated, at least in part, to the iron-rich metal chloride solution. The iron-rich metal chloride solution may originate from carbo-chlorination wastes, spent acid leaching liquors or pickling liquors.

  • Patent number: 8068117
    Abstract: A method and system for synthesizing texture using upsampled pixel coordinates and a multi-resolution approach. The parallel texture synthesis technique, while based on a neighborhood matching technique having order-independent texture synthesis, extends that approach in at least two areas, including efficient parallel synthesis and intuitive user control. Pixel coordinates are upsampled instead of pixel colors, thereby reducing computational complexity and expense. These upsampled pixel coordinates then are jittered to provide texture variation. The jitter is controllable, such that a user has control over several aspects of the jitter. In addition, each neighborhood-matching pass is split into several sub-passes to improve correction. Using sub-passes improves correction speed and quality. The parallel texture synthesis system and method disclosed herein is designed for implementation on a parallel processor, such as a graphics processing unit.
