  • Patent number: 9953046
    Abstract: Displaying pieces of data includes displaying a tree structure on a display device, identifying, in response to a first node being selected from among nodes constituting the displayed tree structure, all nodes connected to the first node in a high-order direction and a low-order direction as a first node group, and identifying, in response to a second node being selected, the second node not being included in the first node group, all nodes connected to the second node in the high-order direction and the low-order direction as a second node group. The second node moves toward the first node according to an operation. A node not to be displayed is determined according to a rule and movement of the second node group. A display device is instructed to display the first node group and the second node group close to each other omitting display of the determined node.

  • Patent number: 9684738
    Abstract: Embodiments relate to generating application-processable commands from character strings. An aspect includes preparing a database in which are recorded keywords for presenting commands as conversion candidate objects, conversion candidate objects, and commands generated when a conversion candidate object has been selected. Another aspect includes receiving a plurality of character strings inputted by a user for an application. Another aspect includes converting a character string of the plurality of character strings to generate a completion candidate character string. Another aspect includes referencing the database when the character string includes a keyword, and presenting, to the user, completion candidate character strings and conversion candidate objects as a conversion candidate list. Another aspect includes generating a command corresponding to a selected conversion candidate object in response to selection of one of the conversion candidate objects from the conversion candidate list by the user.

  • Patent number: 9563974
    Abstract: A display apparatus is adapted to display a plurality of graph structures by aggregating the plurality of graph structures into a single graph structure, where each of the graph structures is made up of a plurality of elements. An acquisition hardware unit acquires graph structures at a plurality of time points in a time series. A distinguishing hardware unit distinguishes unchanged elements and changed elements in the graph structures. An aggregating hardware aggregates the graph structures. A display hardware unit displays the aggregated graph structure such that the unchanged elements and the changed elements are identifiable. A contracting hardware unit contracts two or more unchanged elements and, in response to displaying the aggregated graph structure, displays a single contracted element instead of the two or more unchanged elements.

  • Patent number: 9370375
    Abstract: A surgical instrument including a pre-cut trial mounted on a pre-cut line which is cut shallower than a genuine-cut line. The pre-cut trial is modeled after the genuine implant which is mounted on resected surfaces formed by performing genuine-cutting and comprised of an end resected surface, posterior and anterior resected surfaces, and posterior and anterior chamfer-resected surfaces on the distal end of a femur, and the pre-cut trial is mounted on the pre-cut line, thus observing the extended and flexed positions of the femur and the state of flexion thereof so as to make judgment if the genuine implant is appropriate.
