Abstract: A method for producing graphene, configured for forming a graphene layer on a surface of an object. The method includes steps of: depositing a poly-p-xylene material layer on the surface: and converting the poly-p-xylene material layer into a graphene layer by using a laser sintering process or a plasma-assisted sintering process.

Abstract: Package structures and methods for manufacturing the same are provided. The package structure includes a first bump structure formed over a first substrate. The first bump structure includes a first pillar layer formed over the first substrate and a first barrier layer formed over the first pillar layer. In addition, the first barrier layer has a first protruding portion laterally extending outside a first edge of the first pillar layer. The package structure further includes a second bump structure bonded to the first bump structure through a solder joint. In addition, the second bump structure includes a second pillar layer formed over a second substrate and a second barrier layer formed over the second pillar layer. The first protruding portion of the first barrier layer is spaced apart from the solder joint.

Abstract: A transmission device for suppressing the glass-fiber effect includes a circuit board and a transmission line. The circuit board includes a plurality of glass fibers, so as to define a fiber pitch. The transmission line is disposed on the circuit board. The transmission line includes a plurality of non-parallel segments. Each of the non-parallel segments of the transmission line has an offset distance with respect to a reference line. The offset distance is longer than or equal to a half of the fiber pitch.

Abstract: A method and a system for managing cache files, adapted for a local end apparatus to manage files cached from a service end apparatus, are provided. In the method, a file is divided into a plurality of segments, and a part of the segments are downloaded from the service end apparatus and stored in the local end apparatus. Then, the segments of the file to be downloaded are increased or decreased according to a utility rate of the file.

Abstract: A white balance adjustment method for a digital image capturing device is disclosed. The white balance adjustment method comprises the steps of: setting a color temperature estimation area; capturing an image with the digital image capturing device; choosing one or more analysis blocks from the image; determining whether values of Cb and Cr of each analysis block are located in either a color temperature zone or a white zone of the color temperature estimation area; collecting and calculating each point value of each color temperature that is located in the color temperature estimation area to obtaining a final color temperature; and performing a white balance adjustment procedure according to the final color temperature.
