Abstract: Disclosed is a radio-wave-transmissive cover of a vehicle radar, which exhibits a metallic color and is imparted with improved radio-wave transmission performance. The radio-wave-transmissive cover may include an optical film formed by simultaneously depositing an aluminum (Al) material and a low-melting-point material, such that a radio wave radiated from an antenna of a radar, for example, provided in a vehicle is transmitted. The radio-wave-transmissive cover includes a substrate, and an optical film including aluminum (Al) and a low-melting-point metal having a melting point less than the melting point of aluminum (Al) on the surface of the substrate.

Abstract: Disclosed is a method for producing a sewing data file using an embedded computer. A method for producing a sewing data file of a sewing machine allows the embedded computer to perform the following processes: receiving a color of a thread mounted on the sewing machine through the touch input device and the data input device; receiving an image data through the network device; extracting a color component from the image data by referring to a color of a thread mounted on the sewing machine using the sewing data conversion program; and calculating a ratio occupied by a color of a minimum unit pixel for each separated color as an area occupied by a thread using the sewing data conversion program and converting the calculated ratio into a sewing data in a linear shape and a zigzag shape.
