  • Patent number: 10410416
    Abstract: A computer-executed method is disclosed for collective navigation of distributed virtual reality (VR) devices. The method obtains a source vertex and a destination vertex for a VR device. The source vertex and the destination vertex include vertices of a graph model of a navigable space having a plurality of vertices. The vertices represent a point within the navigable space and the plurality of edges represent a path segment between two corresponding vertices. A subset of possible vertices, selected from the plurality of vertices, is determined for a navigable path. A vertex traffic potential is determined for each vertex of the subset of possible vertices. The navigable path, including one or more consecutive path segments selected to minimize both segment path lengths and vertex traffic potentials, is determined from the source vertex to the destination vertex.

  • Patent number: 10162356
    Abstract: According to a method for selecting a path, the vehicle may receive driving condition of an area from a server, where the driving condition indicates that the area comprises a trouble area. Based on the driving condition of the area, the vehicle may calculate a first path and a second path, each of which is from a first point to a second point. The vehicle may obtain an effect value on vehicle driving associated with a change of weather. Based on the effect value and some other information, the vehicle may calculate a first weighted value for the first path and a second weighted value for the second path. Based on the first weighted value and the second weighted value, the vehicle may select a path. Because the effect value is used to select a path, the path selection in this embodiment may be associated with the change of weather.

  • Publication number: 20180143641
    Abstract: A computing device implements a motion controlling method for an autonomous vehicle. The computing device obtains information of a first path from a current position of the autonomous vehicle to a first next waypoint. When the computing device identifies a target vehicle occupying the first path according to the information of the first path, the computing device sends the information of the first path to the target vehicle, receives a first cost value sent from the target vehicle, wherein the first cost value indicates amount of resources to be consumed by the target vehicle if the target vehicle needs to adjust movement of the target vehicle to enable the first path. The computing device generates information of a second path that starts with the current position of autonomous vehicle based on the first cost value, then move the autonomous vehicle along the second path.

  • Patent number: 9034943
    Abstract: The invention provides a method for preventing discoloration of pyrithione-containing materials, in particular plastic materials or other material such as paints, coatings, adhesives or textiles which are exposed to an outdoor environment. The method is likewise suited for preventing discoloration of other pyrithione-containing materials such as personal care compositions like shampoos. A discoloration inhibitor that includes dehydroacetic acid or a salt thereof is added to the pyrithione-containing material. The discoloration is prevented without the addition of a cyclic organic phosphoric acid ester or an organic phosphite. Use of the discoloration inhibitor does not interfere with the antimicrobial effect of the pyrithione.
