  • Patent number: 9390703
    Abstract: Whereas a high masking effect can be secured in a space to which a masking sound is emitted, the degree of a discomfort a person existing in the space suffers can be reduced. In superimposition processing, a CPU 21 extracts sound signals in different intervals of a sound signal X12-n of a human voice, superimposes the extracted sound signals on each other on the time axis, and outputs a resulting superimposed sound signal X13-n. In shift and addition processing, the CPU 12 interchanges a sound signal, before a reference position, of a sound signal X16-n and a sound signal, after the reference position, of the sound signal X16-n (shift processing) and outputs a sound signal X17-n obtained by adding together a shift-processed sound signal X16?-n and the original, non-shift-processed sound signal X16-n.

  • Patent number: 9331854
    Abstract: Each of ECUs counts the number of messages transmitted for each of CAN IDs. A transmission node that has transmitted a main message produces an MAC from a data field and the CAN ID in the main message and a counter value corresponding to the CAN ID, and transmits the MAC as an MAC message. A reception node that has received the main message produces an MAC from the data field and the CAN ID contained in the main message and the counter value corresponding to the CAN ID, and determines whether the MAC matches the MAC contained in the MAC message. By so doing, verification whether the main message is valid or not can be made. According to this configuration, message authentication by the MAC can be made without changing a CAN protocol.

  • Publication number: 20140086426
    Abstract: There is provided a masking sound output device which prevents interference and an echo even in the case where plural apparatus output the same masking sounds. A masking sound generating unit 11 reproduces each of a disturbing sound, a background sound, and a dramatic sound repeatedly for a prescribed time each time. Return reproduction of each of the disturbing sound and the background sound is started with prescribed timing before it is reproduced fully for the prescribed time. The start timing of the return reproduction varies from one device to another. Unlike the disturbing sound and the background sound, the dramatic sound is not returned halfway; its reproduction timing is adjusted by inserting silent intervals. In particular, the silent interval length of the dramatic sound is varied randomly so that a listener does not recognize the repetition.
