    摘要: A digital watermark embedding apparatus for embedding embedding information, as digital watermark, into an input signal having dimensions equal to or greater than N (N is an integer equal to or greater than 2) and a digital watermark detection apparatus for detecting the digital watermark are disclosed. The digital watermark embedding apparatus generates an embedding sequence based on embedding information, generates a N−1-dimensional pattern based on the embedding sequence, generates N-dimensional embedding pattern by modulating a periodic signal according to a value on the N−1-dimensional pattern, and superimposing the embedding pattern in the input signal and outputs it. The digital watermark detection apparatus measures a component of a predetermined periodic signal in a direction of a dimension of the input signal to obtain a N−1-dimensional pattern, obtains a detection sequence from values of the N−1 dimensional pattern, and detects embedded digital watermark based on a size of correlation value between the detection sequence and an embedding sequence.

    摘要: The power window system moves a window glass in opening and closing directions in response to operation of an opening and closing instruction switch. The power window system includes a measurement device for obtaining an open degree of the window glass and a control device for controlling movement of the window glass in response to operation of the switch. The control device moves the window glass in the closing direction when an open degree obtained by the measurement device is not less than a predetermined degree and in the opening direction when the open degree is less than the predetermined degree.
