  • Information quantity-based reference sensor selection and active noise control using the same
    Patent number: 11948547
    Abstract: An active noise control system selects one reference sensor providing a reference signal with the largest coherence to a noise signal, among a plurality of available reference sensors, as a first entry of a reference sensor set. After selecting the first entry, the active noise control system repeats a process in which a sensor capable of providing the largest information quantity to a current reference sensor set among remaining sensors is selected as a new entry of a reference sensor set, until a desired number of sensors is reached or a desired control level is reached. When the reference sensor set is determined, the active noise control system utilizes the entries of the reference sensor set to generates a noise control signal suitable for canceling the noise signal.

  • Seat for vehicle having fold-and-dive function
    Patent number: 11938849
    Abstract: A seat for a vehicle having a fold-and-dive function is proposed. When a seatback is rotated forwards and folded, a seat cushion is moved down, so the fold-and-dive function of the seat is realized. When a full-flat mode is realized by the reclining operation of the seatback, a rear end of the seat cushion is moved up, so a step between the seat cushion and the seatback can be significantly reduced or eliminated. Furthermore, a front link connecting a back cushion interlocking frame and a cushion fixing bracket to perform the fold-and-dive function is installed to have directivity where it is inclined rearwards, thus preventing a submarine phenomenon of the seat in the event of a forward collision.
