  • Publication number: 20150003613
    Abstract: An immobilizer ECU generates an encryption key using key generating logic, from a SEED code included in an ID code signal sent from an electronic key, and registers the encryption key to the immobilizer ECU. The immobilizer ECU receives an instruction from a registration and deletion tool and sends, to the electronic key, a deletion request signal that requests the deletion of the SEED code. The electronic key deletes the SEED code from the electronic key if a deletion request signal has been received.

A storage device stores a plurality of documents that have various formats. A pattern candidate creating unit receives a list of input words that are selected as samples among phrases that are to be included in a dictionary. The pattern candidate creating unit selects one document, determines forward and backward character strings of input words in the selected document as candidates of patterns, and stores the forward and backward character strings as a pattern candidate. The pattern candidate creating unit executes the above processes for each of the documents. A phrase candidate creating unit extracts phrases interposed between patterns included in the pattern candidate as candidates of phrases to be output, and stores the extracted phrases as a phrase candidate.

  • Publication number: 20130080215
    Abstract: Activity information obtainer (10a) of intellectual productivity measurement device (100) obtains activity information representing an activity. Event information obtainer (10b) obtains information representing an event and including a time at which the event occurs. Evaluation obtainer (4) obtains a subjective evaluation. Short-term-context input section (11a) generates a short-term context from the activity information. Long-term-context input section (11b) extracts a long-term context from event information. Model generator (5) generates, using a mapping function from a direct sum space of the space of the short-term context and the space of the long-term context to the space of the subjective evaluation, an estimation model that is a parameter of the mapping function in such a way that values reflecting the short-term context and the long-term context enter within the range of the subjective evaluation.
