Abstract: Disclosed in the present invention is a floating hologram system. The floating hologram system includes a diffuser configured to form a projection image using light beams transmitted from an image transmitter and diffuse the formed image, and a holographic optical element on which the image diffused from the diffuser is incident and which generates a virtual image floating at a position a predetermined distance therefrom and has a convex lens characteristic. A distance between the diffuser and the holographic optical element is determined based on a focal length of the holographic optical element and a distance from the holographic optical element to the virtual image.

Abstract: Provided are a webserver-based video content production system and method for printing a holographic stereogram photo. According to the webserver-based video content production system and method, an encoding process is performed on image data under a web environment to prevent data loss in a network communication process, and then the encoded image data is transmitted to a webserver. The webserver decodes the encoded image data and performs a second-half task (postprocessing) on the decoded image data using deep learning such that a high-quality hologram photo can be printed within a relatively short time without any unnecessary process.

Abstract: Proposed is a coupler structure of a hand grinder. The coupler structure is fastened to a rotating shaft of a grinder body to enable a machining disc to be more simply and rapidly attached to or detached from the grinder body. Fabrication costs are significantly reduced by simplifying the components associated with the coupler mounted on the rotating shaft of the grinder body. Since the consumable disc is easily attached to and detached from the coupler with one touch, a replacement operation is performed rapidly, thereby significantly improving the efficiency of work.
