Abstract: An image acquisition apparatus for acquiring an in-game 360 virtual reality (VR) image by using a plurality of virtual cameras includes a virtual camera group taking in-game images by using the plurality of virtual cameras. The image acquisition apparatus may also include a renderer generating textures for the taken images, generating a panoramic image by performing an equirectangular projection (ERP) mapping of the generated textures, and encoding the generated panoramic image. The image acquisition apparatus may further include an image generator generating a 360 VR image by combining audio information with the encoded panoramic image.

Abstract: Embodiments of the present inventive concepts provide a semiconductor device including a substrate that includes an active pattern, a channel pattern disposed on the active pattern, a first source/drain pattern and a second source/drain pattern that are connected to the plurality of semiconductor patterns, a gate electrode disposed on the plurality of semiconductor patterns, and a first active contact electrically connected to the first source/drain pattern and a second active contact electrically connected to the second source/drain pattern. In one aspect, the channel pattern includes a plurality of semiconductor patterns that are spaced apart from and vertically stacked on each other. In one aspect, the gate electrode includes inner electrodes disposed between neighboring semiconductor patterns of the plurality of semiconductor patterns and an outer electrode disposed on an uppermost semiconductor pattern.

Abstract: A refrigerator includes a body having a storage space for keeping food at low temperature, a door movably attached to the body to selectively open and close the storage space, a first shelf movably provided in the storage space and having a first side surface, a second shelf movably provided in the storage space next to the first shelf and having a second side surface which faces the first side surface of the first shelf, a first pressing portion including a plurality of protrusions formed on the first side surface of the first shelf, and a second pressing portion formed on the second side surface of the second shelf and facing the first pressing portion.

Abstract: A system for tracking location of person having signal transmitter includes at least one receiver for receiving unique ID signal transmitted by signal transmitter that transmits ID signal uniquely determined for respective mobile signal transmitter at at least one predetermined period. The receiver receives unique ID signal near circumference of the person having signal transmitter spaced apart from the receiver by given distance, and stores the received unique ID signal in ID store unit. The receiver, when search request for specific ID is received from external server, searches for the requested ID in ID store unit and transmits transmission information including ID corresponding to requested ID to external server. The person, such as abducted person, has only small signal transmitter, and thus the current location of the abducted person and path along which the abducted person moved can be tracked using the signal continually transmitted by the signal transmitter.

Abstract: An embodiment relates to a refrigerator. According to a refrigerator of an embodiment of the present invention, there is not difference in a plurality of shelves arranged continuously in parallel with each other.
