  • Patent number: 8285479
    Abstract: A parking assist apparatus for guiding a vehicle to a target parking position includes an initial position guiding unit configured to generate an initial position guiding path at a predetermined timing, the initial position guiding path leading from a current position of the vehicle to an initial position where vehicle guidance to the target parking position is started. The initial position guiding unit is also configured to guide the vehicle along the initial position guiding path to the initial position. The apparatus also includes an obstacle detecting unit configured to detect an obstacle around the vehicle. When the obstacle detected by the obstacle detecting unit is located along the initial position guiding path, the initial position guiding unit generates the initial position guiding path such that the obstacle detected by the obstacle detecting unit can be avoided.

  • Patent number: 8116857
    Abstract: There is provided a non-linear signal separation method using the non-linear state space projection method capable of separating an effective non-linear signal even if the S/N ratio is low by performing the time domain high speed non-linear state space projection when a signal is a multi-channel signal and has a periodicity. In the non-linear signal separation method using the non-linear state space projection method, an original signal having a complex signal which is a multi-channel and cyclic signal measured from one phenomenon is processed by using the time domain high-speed non-linear state space projection method so as to estimate a noise in the original signal and subtract the estimated noise from the original signal, thereby separating the signal to be measured in the original signal as a non-linear signal even when the S/N ratio is low.
