Abstract: A display device includes a substrate and a plurality of unit pixels disposed on the substrate. Each unit pixel includes a plurality of sub-pixels, a plurality of light sensing pixels, and a plurality of partition wall members. Each of the sub-pixels includes a light emitting element that emits light and a light emitting area from which the light is emitted. Each of the light sensing pixels includes a light receiving element that outputs a sensing signal corresponding to the light and a light receiving area that receives the light. In a plan view, each of the partition wall members surrounds the corresponding light receiving area and overlaps at least some of the sub-pixels.

Abstract: An electrified vehicle includes: a battery; a motor drive device configured to drive a motor through an inverter, based on a voltage of the battery; and a battery controller configured to determine whether to perform output limiting on the battery, based on whether a ratio of regenerative braking is less than or equal to a preset ratio, wherein the ratio of regenerative braking is varied according to an amount of charging of the battery and an amount of discharging of the battery within a preset time interval, and adjust, based on the output limiting being performed on the battery, a derate ratio associated with a battery output limit value.

Abstract: A method for providing data associated with a shopping mall web page includes accessing a review item written by a user ID in association with the shopping mall web page, the review item including an image and a text; detecting at least one target object from the image included in the review item; processing the detected target object to generate first feature data; processing a reference object included in the shopping mall web page to generate second feature data corresponding to the reference object; and outputting verification data indicating a result of verification for the review item by comparing the first feature data, generated by processing the target object, with the second feature data, generated by processing the reference object.

Abstract: A method and system for providing a search keyword list are provided. The search keyword list providing system includes an initial letter receiving unit to receive at least one initial letter from a user terminal; a list providing unit to provide a first search keyword list that contains at least one automatically completed search keyword related to the at least one initial letter; and a middle letter receiving unit to receive a middle letter related to any one of the at least one initial letter from the user terminal, wherein the list providing unit provides the user terminal with a second search keyword list that contains at least one automatically completed search keyword related to the at least one initial letter and the middle letter when receiving the middle letter.

Abstract: A method of setting an equalizer so as to enlarge a sound field in reproducing an audio file and a method of reproducing an audio file thereby, includes: dividing an input audio file into segments with a predetermined time length; extracting an audio feature value for each segment; determining equalizer information for reproducing each segment by the use of the extracted feature value; and determining an equalizer sequence for the audio file by the use of the determined equalizer information of each segment. Since the equalizer setting information can be automatically changed without user manipulation, the user can listen to an audio file of which the sound field is dynamically enlarged.

Abstract: A method which allows multimedia players to analyze features of a music file so as to classify the music file, and a system therefor are provided. The method of classifying a music file includes pre-processing to decode and normalize at least a part of an input music file, extracting one or more features from the pre-processed data, and determining the mood of the input music file using the extracted features.
