摘要:
A beat density detecting apparatus and an information playback apparatus are provided to detect distinctive characteristics that music or the like has and to provide the same as a novel information volume. Playback data read out from an information recording medium, such as an optical disc, and sub-code data containing the information of an elapsed track time indicating a recording position of the playback data are provided to a beat detecting unit and a beat position detecting unit, respectively. The beat detecting unit detects the number of occurrences of a change in amplitude at each predetermined frequency of the playback data, and the beat position detecting unit detects an elapsed track time from the sub-code data. Further, a beat density computing unit finds the number of occurrences with respect to the elapsed track time as the characteristics information of a beat density. By displaying the characteristics information of the beat density on a display unit in a way that the user or the like can visually recognize, it is possible to provide the distinctive characteristics that music or the like has not as instantaneous characteristics, but as the characteristics of a relatively long period, or the whole of the characteristics of a signal subject to audio playback.

A sound-processing apparatus is provided that is capable of creating a sound effect without having to worry about changes in parameters such as the beat of the input sound source. The sound-processing apparatus comprises: a delay unit DB that generates at least one or more new synchronized sound signal that is synchronized with a sound signal Si to be modulated; parameter-detection unit 6 that detects a parameter that indicates an attribute of the generated synchronized sound signal; a signal-conversion unit 8 that generates a converted signal Sdm based on the detected parameter; and a modulation unit that modulates the sound signal based on the generated converted signal Sdm.

The invention provides a wind turbine generating apparatus capable of controlling a temperature in a rotor head. In a wind turbine generating apparatus in which a driving/generating mechanism coupled to a rotor head having wind turbine blades attached thereto is housed in a nacelle, and control devices are housed in a hub of the rotor head, an air circulation guide is provided for allowing air to circulate between an inside of the rotor head and an inside of the nacelle via a communication path formed between the rotor head and the nacelle.

An object detection system includes a radar detection portion that detects first lateral position information relating to the lateral position of an object with respect to a host vehicle, by transmitting a transmission wave and receiving a reflection wave reflected by the object; an image detection portion that detects second lateral position information relating to the lateral position of the object with respect to the host vehicle, based on the captured image of the object; a distance detection portion that detects a distance between the host vehicle and the object; and a lateral position estimation portion that estimates the lateral position of the object based on the first lateral position information and the second lateral position information. When the lateral position of the object is estimated, the lateral position estimation portion changes each of a weight assigned to the first lateral position information and a weight assigned to the second lateral position information according to the distance.

A laser radar device mounted on a vehicle includes a first laser emission part configured to generate a measuring laser beam by using a laser beam emitted from a laser source and to illuminate a predetermined area in a front traveling direction and a second laser emission part configured to generate a measuring laser beam by using the laser beam emitted from the laser source. A beam spread angle, viewed from a side of the vehicle, of the measuring laser beam generated by the second laser emission part is larger than a beam spread angle, viewed from a side of the vehicle, of the measuring laser beam generated by the first laser emission part.
