Abstract: A vehicle parking control device has a processor and a memory to control the vehicle from a starting to a target parking position. The vehicle control device includes an obstacle detection unit detecting obstacles around the vehicle, a travelable area setting unit setting an area where the vehicle can travel based on a position of the obstacles, and sets the target parking position in the travelable area, a route generation unit calculating a travel route to the target parking position in the travelable area, and a parking execution unit that causes the vehicle to travel toward the target parking position on the basis of the travel route. The route generation unit generates a route from a parking start position to the target parking position, and corrects a distance of the section to a predetermined distance when the distance of the section is less than the predetermined distance.

Abstract: A shot peening apparatus capable of precisely controlling the amount of shots supplied projects, by a shot impeller, shots onto a workpiece, and has a bucket elevator which conveys the shots to a predetermined height, a motor which drives the bucket elevator, and a control device which controls the current value of the motor. The control device issues an alert when the current value of the motor becomes lower than a predetermined current value.

Abstract: A pyrene based compound and its use in an organic light emitting device (OLED) according to the following formula: In the above formula, Z1 represents a hydrogen atom, deuterium atom, oxygen atom, silicon atom, selenium atom, substituted or unsubstituted aryl group, substituted or unsubstituted heteroaryl group, substituted or unsubstituted aryl amine or a combination thereof, and Z2 represents a hydrogen or deuterium atom. One of Y1 and Y2 represents a hydrogen atom, deuterium atom, oxygen atom, silicon atom, selenium atom, a substituted or unsubstituted aryl group, substituted or unsubstituted heteroaryl group, substituted or unsubstituted aryl amine or a combination thereof, and the other of Y1 and Y2 represents a hydrogen or deuterium atom. X1 through X6 independently represent hydrogen atoms, deuterium atoms, alkyl groups or aryl groups, and at least one of X1 through X6 represents a bulky alkyl group or bulky aryl group.

Abstract: A Karaoke apparatus responds to a request message for performing an entry song. The Karaoke apparatus has a music data storage for storing music data representative of a plurality of entry songs, and a reference data storage for storing reference data representative of a multiple of key items which specify the entry songs. A microphone is provided for collecting an oral request message and for converting the same into a corresponding voice signal. The voice signal is analyzed to extract therefrom key information which suggests a desired entry song. The reference data storage is searched to detect coincidence between the key information and at least one of the key items to thereby identify the desired entry song. The Karaoke apparatus retrieves music data of the desired entry song from the music data storage to perform the desired entry song according to the retrieved music data.

Abstract: A karaoke system sounds a karaoke song designated according to a request command. The system includes a record unit defining a closed data source for readably recording a karaoke song, and a playback unit for reading the record unit to reproduce an audio signal representative of the karaoke song such that the record unit and the playback unit compose a playback karaoke equipment. The system further includes a supply unit defining an open data source for accessibly supplying a song data prescriptive of a karaoke song, and a synthetic unit for processing the supplied song data to synthetic size an audio signal representative of the karaoke song such that the supply unit and the synthetic unit compose a synthetic karaoke equipment. A total control unit is provided for selectively activating either of the playback and synthetic karaoke equipments according to a request command to achieve efficient use of the closed and open data sources.
