Abstract: A method and apparatus for upgrading software of a video device is disclosed. A software program associated with the video device is downloaded using wireless communication to upgrade the video device. This allows the software program to be more quickly downloaded. The apparatus includes a tuner unit, a storage unit, and a controller. The tuner unit receives a plurality of ROM files into which a software program associated with a video device has been divided. The storage unit stores the received ROM files. The controller reads the stored ROM files and upgrades the video device.

Abstract: The object of this invention is to provide a leisure sports helmet having both a fan and a plurality of vents on a helmet body. Due to the fan (100) and the vents (20), atmospheric air is drawn into the interior of the helmet to cause convection to transfer heat from the head of a user to the air, and the heated air with sweat is discharged to the atmosphere. Thus, the helmet is forcibly ventilated while the user wearing the helmet participates in rapid leisure sports, so that the helmet does not generate any odor caused by the heat and sweat in the interior of the helmet and maintains a pleasant and comfortable atmosphere. The fan collaterally provides a decoration effect to make the appearance of the helmet more attractive.

Abstract: Disclosed herein is a three-dimensional (3-D) shaping apparatus and method using a non-contact type heating tool. The 3-D shaping apparatus includes three feeding units, an indexing table and a non-contact type heating tool. The feeding units move in three different directions perpendicular to each other. The indexing table includes a support frame provided with support arms uprightly extending, a seating member hinged to the support arms, and a fixing chuck rotatably combined with the seating member and adapted to grip one side of a soft material. The seating member is placed to be rotated around one of the three moving directions of the three units, and the fixing chuck is placed to be rotated around a rotating axis perpendicular to a rotating axis of the seating member. The non-contact type heating tool is mounted on one of the feeding units to shape soft material by thermally resolving the soft material without contact with the soft material.
