  • Publication number: 20180004354
    Abstract: An information reception device is provided with: operation surface which is adjusted to produce a characteristic index vibration by an object contact; a storage device stores candidate information (candidate information is related with the index vibration) which serves as a candidate of input information; a microphone which acquires observation information according to observation of the actual vibration arising in the surrounding environment; and a CPU. The CPU (selecting part) judges whether or not the index vibration exists in the observation information acquired. When the CPU judges that the index vibration exists, the CPU selects the candidate information which is related with the index vibration as the input information.

  • Patent number: 7996603
    Abstract: A refresh controller transmits two refresh request signals of a first request signal which indicates a time at which a refresh operation of a DRAM may be performed and a second request signal which indicates a time at which a refresh operation of the DRAM must be performed, to an arbitrator. On the other hand, also transfer request signals each of which requests a data transfer are transmitted from plural data transfer parts, respectively, to the arbitrator. If no transfer request signal is input when a first request signal is input to the arbitrator, a refresh operation of the DRAM is performed. As a result, a refresh operation is performed when the crowding level of a bus is relatively low. This improves an efficiency in a data transfer.
