  • Publication number: 20180211647
    Abstract: An active noise reduction device reduces noise in a space within a vehicle body. The active noise reduction device includes a first input unit, a signal processor, and an abnormality determiner. The first input unit acquires, from a first vibration detector fitted to the vehicle body, a first signal that indicates a magnitude of vibration in a specific part of the vehicle body. The signal processor generates a cancellation signal that is used to output a cancellation sound for reducing the noise, by using the first signal as a reference signal having a correlation with the noise. The abnormality determiner determines whether or not an abnormality is present in the specific part by using the first signal.

  • Patent number: 9646596
    Abstract: In an active noise reduction device, in order to solve this problem, a control block determines a level of a reference signal detected by a level detection unit. If determining that the level of the reference signal is small, the control block decreases a level of a cancel signal. This operation suppresses generation of an abnormal sound even if a level of a noise is small.

  • Publication number: 20070133578
    Abstract: In a network gateway, when a target communication frame is transferred bit-by-bit from at least one of nodes through a corresponding one of networks, a receiving unit sequentially receives the transferred target communication frame bit-by-bit, and sequentially outputs the received target communication frame bit-by-bit. A buffer sequentially stores therein the bits of the target communication frame sequentially output from the receiving unit. A destination determining unit works, concurrently with the buffer, to receive, bit-by-bit, the target communication frame output from the receiving unit and to, when receiving an identifier of the target communication frame, determine a destination network of the target communication frame based on the received identifier. A transferring unit is operatively connected to the buffer and transfers, bit-by-bit, the target communication frame stored in the buffer to the destination network determined by the destination determining unit.
