  • Patent number: 9407553
    Abstract: When a reduction in the transmission speed of the line preset as the TDM line transfer route is detected by a device-connecting line termination unit, a mapping request, to which information indicating the amount of TDM-line bandwidth overflowing from the line and a destination indicating the final line relaying device have been added, is generated by the mapping request processing unit, and transmitted via the other line to another device connected in a ring network in order to map the overflow amount of bandwidth added to the mapping request on each line sequentially from the other device to the line relaying device as the final transfer destination, thereby forming a TDM-line detour route.

  • Patent number: 9019831
    Abstract: [Problem] The problem is to carry out the QoS control which tracks a change in a state of an outward line. [Means for solving the problem] A network repeater according to the present invention includes: a flow control means to carry out flow control for restricting inflow of a data flow which is received through an inward line; a bandwidth control means to carry out bandwidth control of controlling a bandwidth of a data flow which is received through the inward line and is sent through an outward line; and an outward line monitoring means to monitor a change in a state of the outward line. In the case that the monitored state of the outward line satisfies a specified condition which is determined in advance, either the flow control or the bandwidth control is carried out on a condition corresponding to the specified condition.

  • Publication number: 20150029214
    Abstract: A display device superimposes and displays guide information on an actual image captured by a camera. The display device includes a specifying unit and a display control unit. The specifying unit specifies an overlapping part between guide information and a building in the actual image based on an image-capturing position, position information of the building existing in an image-capturing range of the camera, building shape information of the building, and position information of a facility or a road corresponding to the guide information. The display control unit superimposes and displays the guide information except for a cut-off part on the actual image. The cut-off part herein indicates the overlapping part where the building is to be displayed on a front side of the guide information.

  • Patent number: 7822541
    Abstract: A map creation device includes a simple-ground-information creating unit, an on-ground-structure-information creating unit, and a map-information creating unit. The simple-ground-information creating unit creates, based on the ground object, a simple ground object expressing the three-dimensional shape with less amount of data than the ground object. The on-ground-structure-information creating unit creates, based on the simple ground object, an on-ground-structure object expressing a three-dimensional shape of an on-ground structure that is present on a surface of the ground by adding height information to a two-dimensional on-ground-structure object expressing a two-dimensional shape of the on-ground structure. The map-information creating unit creates map information in which the on-ground-structure object is superimposed on the ground object.

  • Patent number: 7633500
    Abstract: A ground object is arranged so that it overlaps with a cylindrical object. Inside the cylindrical object, foot data of the ground object is arranged. Since the foot data on the side of a fore-end opening is positioned behind a fore-end face object with respect to view point coordinates, hidden surface removal is carried out for an image of the foot data on the side of the fore-end opening viewed from the view point coordinates by a Z value of a transparent drawn image of the fore-end face object.

  • Publication number: 20080238914
    Abstract: A 3D road object is an object having road width, height, and length. The 3D road object corresponds to a link. A road surface texture is drawn repeatedly on the top surface of the 3D road object. With a map information creating device, geometry data in a cube shape containing a cross-section including the road width and the height can be extracted. Length of this geometry data can be set to the length of one sheet (one cycle) of the road surface texture in the length direction of the 3D road object. The road surface texture for one sheet as well as drawing cycle information can also be extracted. Moreover, link length information can be extracted from the link.

  • Publication number: 20070200845
    Abstract: In a map creation device (100), a simple-three-dimensional-ground-information creating unit (104) creates, using a three-dimensional ground object indicating a three-dimensional shape of a ground, a simple-three-dimensional ground object having less amount of data than the three-dimensional ground object. A three-dimensional-on-ground-structure-information creating unit (105) adds, using the simple-three-dimensional ground object created, height information to a two-dimensional on-ground-structure object indicating a two-dimensional shape of an on-ground structure present on a surface of the ground. Then, a three-dimensional on-ground-structure object indicating a three-dimensional shape of the on-ground structure is created. A three-dimensional-map-information creating unit (106) creates three-dimensional map information based on the three-dimensional ground object and the three-dimensional on-ground-structure object.

  • Patent number: 6999075
    Abstract: A three-dimensional information display apparatus which has three-dimensional map information processing section adapted to process three-dimensional map information, three-dimensional route information processing section adapted to process three-dimensional route information, and three-dimensional information display section adapted to display the three-dimensional map information processed by the three-dimensional map information processing section and the three-dimensional route information processed by the three-dimensional route information processing section. If a road to the destination included in the three-dimensional map information contains a downward branch part, the three-dimensional route information processing section processes the three-dimensional route information so as to extend a part of a route to the road to be branched for display while maintaining the same height as the height on drawing of the route to the destination at the downward branch part.
