Abstract: A steering wheel attachment device removably connected to at least a portion of a steering wheel of a vehicle, the steering wheel attachment device including a main body, and a pressure dissemination unit disposed within at least a portion of the main body to provide a pressured sensation to the steering wheel corresponding to a touch by a user.

Abstract: A grit chamber for a wastewater treatment plant. A vertical floodgate is installed on a partitioning wall and is driven in a vertical direction to be opened downwardly from a top toward a bottom. A floodgate driving motor is coupled to one end of the vertical floodgate to directly drive the vertical floodgate. An inflow amount measurement means functions to stepwisely measure a flow amount of wastewater which passes through a wastewater tank. A control section is connected to the floodgate driving motor and the inflow amount measurement means to control the floodgate driving motor in response to a measurement result of the inflow amount measurement means. A wastewater level is adjusted within a predetermined range through operation of the vertical floodgate to maintain a constant flow velocity of wastewater which passes through a sand sedimentation zone, thereby preventing organic material which is contained in the wastewater and is other than sand, from sedimenting.

Abstract: The invention provides a video summary service providing apparatus and method, and more particularly, provides a video summary service providing apparatus and method in which a summary image of a video is generated by considering a resources state of a device for summarizing the video and an expected replay time used in summarizing desired by the user, and the generated summary image, prepared to be suitable for a replay time desired by the user, is provided to the user.

Abstract: The invention relates to a method and apparatus for determining a genre of multimedia data by analyzing the multimedia data, the apparatus including: a feature extractor extracting predetermined feature information from multimedia data; and a genre determination unit analyzing the extracted feature information of the multimedia data according to multimedia data genre determining logic associated with the extracted feature information and determining a genre of the multimedia data.

Abstract: The present invention relates to a plasma display apparatus having different widths of data signals applied to an address electrode in the address period. Particularly, data signals are set to have different rising time, sustain time, and falling time such that the picture quality reduction and the driving efficiency degradation due to a misdischarge in the address period can be improved, and the circuit damage by the peak current can be prevented.

Abstract: A plasma display apparatus includes an address driver for applying a predetermined waveform to an address electrode so that the predetermined waveform overlaps a sustain pulse applied to a scan electrode or a sustain electrode during a sustain period. As a result, it is possible in accordance with at least one embodiment to improve image quality by preventing erroneous discharge that may occur after the start of a sustain period.
