Abstract: An optical disk device includes a reproduction component, a determination component, a memory component, a communication component, and an output component. The reproduction component reproduces contents stored in optical disks. The determination component determines genres of the contents while the reproduction component reproduces the contents. The memory component stores a first table that associates each of the genres that have been determined by the determination component with a reproduction counter that indicates a number of times the reproduction component has reproduced the contents that belong to each of the genres. The communication component downloads from a server advertising data corresponding to one of the genres stored in the first table. The one of the genres is selected based on the reproduction counter of the first table. The output component outputs an advertisement based on the advertising data that is downloaded by the communication component.

Abstract: Timer action is done from the time point t.sub.1, where the detected vehicle speed determined by the vehicle speed signal S.sub.2 is 0, until the time point t.sub.6, where the detected vehicle speed exceeds 0, thereby determining the timer time T. The value of the axle load signal S.sub.1 is transiently held, beginning at the time point t.sub.2 where the period of time X has passed since t.sub.1. When the timer time T is longer than the set timer time T.sub.0, the value of the axle load signal S.sub.1 at the time point t.sub.5, the point chronologically backward by the period of time Y from t.sub.6, is read. Based on this read value, the opening of the control valve is adjusted to vary the assist force. Thus, even when a vibration occurs in the vehicle body during driving, the assist force by the power steering system is made constant, whereby a feeling during steering can be improved.

Abstract: A pitch detecting device includes an inverse filter for receiving a voice signal and subjecting the voice signal to inverse filter processing, thereby obtaining a residual signal of the voice, a correlation calculating circuit for obtaining an autocorrelation function of an output of the inverse filter, a detector for detecting a maximum value of the output from the correlation calculating circuit and outputting it as a pitch of the voice signal, and a circuit for receiving the voice signal, extracting spectrum data of the voice signal, and controlling the order of the inverse filter in accordance with the spectrum data.

Abstract: A telephone signal transmission device capable of transmitting and receiving dial pulses in a network system which includes a telephone exchange is disclosed. Transitions of a connection signal are detected to allow a connection signal to be transmitted only when the transmission of a speech signal is needless. When the connection signal has a stable state (i.e. high or low) within a frame, only one bit is transmitted. The device effectively utilizes substantially all of the transmission bits for speech.

Abstract: In a speech presence detector, the input signal (speech plus noise) is detected for power and spectral-variation per unit time. Speech presence is decided if high-power or a sudden large variation in spectral-distribution (for example, unvoiced to voiced sound) is detected.
