Abstract: A system, computer-readable storage medium storing at least one program, and a computer-implemented method for determining a zoom factor of content displayed on a display device is presented. An image is obtained from a camera oriented toward a viewing position of the display device, where the image includes a viewer of the display device. The image is normalized based on specification of the camera to produce a normalized image. The normalized image is analyzed to determine a distance between the display device and the viewer of the display device. A zoom factor for content is determined based on the distance between the display device and the viewer of the display device. Content is displayed on the display device using the zoom factor.

Abstract: An anti-freezing apparatus and an anti-freezing method using the same are provided. The anti-freezing apparatus includes: a nozzle which sprays anti-freezing liquid to a wind shield; a storage container which stores the anti-freezing liquid; a pump which delivers the anti-freezing liquid stored in the storage container to the nozzle; and a controller which controls the driving of the pump in a stop state and allows the anti-freezing liquid to be sprayed through the nozzle.

Abstract: Disclosed is a method of preparing a glycol mono-tertiary-butyl ether compound using a C4 hydrocarbon mixture containing isobutene and a glycol compound as reactants, in which a glycol di-tertiary-butyl ether compound as a byproduct is decomposed into isobutene and a glycol compound and the obtained isobutene and glycol compound are recycled as reactants, whereby product yield per unit raw material may be maximized.

Abstract: The present invention relates to a projector for outputting advertisement images, and it is an aim of the present invention to provide a projector for advertisement images which can project advertisement images onto surfaces of windows in a train. For this purpose, the projector of the present invention comprises: an image-processing unit installed in the engine room of the train to play back advertisement images; image distribution units installed in the respective passenger cars of the train to receive the advertisement images by communicating with the image-processing unit; and a plurality of image output(display) units arranged at a predetermined interval and close to the windows in the passenger cars so as to output, onto the windows, the advertisement images transmitted from the image-processing unit and received by the image distribution units, such that the advertisement images can be projected onto the surfaces of the windows.

Abstract: Disclosed is a method of preparing isobutene in which high-purity isobutene is separated (prepared) from a C4 mixture by cracking glycol ether prepared from a C4 mixture (in particular, C4 raffinate-1) containing isobutene and a glycol. The method includes cracking glycol ether into isobutene and glycol at a temperature between 50° C. and 300° C. in the presence of a strongly acidic catalyst. The glycol ether may be prepared by reaction between a C4 mixture containing isobutene and glycol in the presence of an acid catalyst.

Abstract: The present invention relates to a socket assembly for testing semiconductor device comprising a socket board electrically connected to an outside testing device wherein a plurality of connection pins connected to leads of a semiconductor is provided; a socket guide mounted to cover the socket board, with an open part formed so that the semiconductor may in/out, thereby connecting the semiconductor to the connection pins of the socket board; and a spacer interposed between the socket board and the socket guide for maintaining a predetermined distance between the semiconductor and the socket board by touching an surface of the semiconductor having moved into an inside of the socket guide before a surface of each carrier touches the socket guide. According to the present invention, the balls or the leads of each semiconductor may be pressed to the connection pins of the socket in a predetermined depth without replacing the carriers though the semiconductors have the different thicknesses.

Abstract: A drag type wheel finishing machine. A spindle is connected to an output shaft of a drive motor secured to an upper platform of a frame structure. Arms are mounted adjacent to a lower end of the spindle. Upright members are joined to distal ends of the arms. Wheel mounting parts are mounted to lower ends of the upright members, and an abrasive polishing media bath is placed in the frame structure to be raised and lowered by a lift mechanism. The lift mechanism is configured such that the media bath can be guided by four columns and supported by four wires. One ends of the wires are connected to a distal end of a piston rod of a drag type hydraulic cylinder installed on the media bath such that, when the wires are simultaneously pulled via the piston rod, the media bath is raised.
