  • Patent number: 8831945
    Abstract: A text in a corpus including a set of world wide web (web) pages is analyzed. At least one word appropriate for a document type set according to a voice recognition target is extracted based on an analysis result. A word set is generated from the extracted at least one word. A retrieval engine is caused to perform a retrieval process using the generated word set as a retrieval query of the retrieval engine on the Internet, and a link to a web page from the retrieval result is acquired. A language model for voice recognition is generated from the acquired web page.

  • Patent number: 8392987
    Abstract: A user terminal displays on its display unit a target web page including an authentication information input field into which input authentication information is inputted by the user terminal. The user terminal judges first to third validity levels for a plurality of login history information by referring to a login information list and a service group information. The user terminal selects a corresponding process from a plurality of predetermined processes for the input authentication information based on existence or absence of the login history information in the first or second validity level and on a result of checking the input authentication information with login information in the login history information in the first to third validity levels. The user terminal executes the corresponding process.

  • Publication number: 20090138842
    Abstract: A behavioral synthesis system has a scheduling unit and a mode control unit. The scheduling unit performs scheduling of a behavioral level description with reference to a resource quantity data indicating resource constraint and a resource delay data indicating delay times of respective resources. A single process described in the behavioral level description is divided into a plurality of description blocks, and a scheduling mode among a plurality of scheduling modes is designated with respect to each of the plurality of description block. The mode control unit refers to a mode designation code that indicates the designated scheduling mode and controls such that the scheduling unit performs the scheduling with respect to each description block in accordance with the designated scheduling mode indicated by the mode designation code.

  • Patent number: 7216327
    Abstract: A device for estimating the required number of board layer to provide necessary wiring in a printed circuit board or a LSI package, a system including the device, a method and a program for estimating the same. In this system, positional information of pins mounted to each component and a board, and connection information between pins are retrieved from a pin positional information file and a net list file. Further, information about an order of layers to be added, a diameter of a via in respective layers and obstacles to wiring is retrieved from the net list file an added layer structure defining file. Thereafter, information about a layer structure, vias, an area where wiring is prohibited is stored in a storage. A wiring route searching section determines whether or not it is possible to form necessary wiring under the present structure. When the wiring route searching section determines it to be impossible, a layer in the next order is added according to information about added layers.
