摘要： A method and apparatus for forming three dimensional objects by laser sintering that includes depositing the required quantities of powder for two successive layers on one side of the process chamber and simultaneously spreading the first layer while transporting the second layer quantity to the opposite side of the process chamber. The invention includes steps of parking the quantities of powder in sight of the part bed heater to pre-heat the powder and flattening the powder wave before the pre-heating step to improve pre-heat efficiency. This method and apparatus can result in reduction of the mechanisms, size, cost, and increase productivity of a laser-sintering device.

摘要： Disclosed is a method of electroplating a printed circuit board using a magnetic field having periodic directionality, in which the printed circuit board is electroplated using a magnetic field that is generated substantially perpendicular to a current direction and that has periodic directionality between a forward wave and a reverse wave. According to the method of the present invention, since the magnetic field having the periodic directionality is used, the aging of the plating solution may be prevented and the ionic concentration thereof may be made uniform even without the use of an external liquid flow device, and as well, the substrate may be uniformly plated.

摘要： A video decoding system is provided. When a DDR SDRAM is used as an external memory, MBs are rearranged and then stored to minimize memory access operations for the MBs at the DDR SDRAM and unnecessary additional word read operations caused by a DDR characteristic. Accordingly, the video decoding system can efficiently perform a memory access operation on MBs for video display and frame decoding by the video decoder. Specifically, the decoding system can reduce the total video decoding time, thereby allowing a surplus memory use time for additional functions of a digital broadcasting receiver.

摘要： The invention is a method for controllably cooling at least a portion of a part-cake from a laser sintering system to minimize cool down time, maximize throughput, and minimize thermal gradients within the part-cake. The method generally comprises forming one or more thermal transfer channels within the part-cake. The thermal transfer channels can include ducts and cooling fins in the part-cake surrounding the formed part. The method can further comprise removing unfused powder from the ducts and introducing cooling media into the ducts. The invention also includes a part-cake having thermal transfer channels formed therein and a laser sintering apparatus comprising a part-cake containing cylinder having permanent fittings therein for receiving terminal portions of thermal transfer channels formed in the part-cake.

摘要： A video encoding method, a video encoder, and a Personal Video Recorder (PVR) are disclosed. The PVR includes: a first video decoder for decoding an input MPEG-2 video signal, calculating reference picture information of the MPEG-2 video signal and a motion vector of a reference picture, and outputting the calculated result; a first video encoder for encoding the decoded MPEG-2 video signal into a H.264 video signal using the motion vector and the reference picture information generated from the first video decoder; and a storage unit for storing the H.264 video signal generated from the first video encoder. Therefore, the PVR can effectively transcode the MPEG-2 format image into the H.264 format image, can display a desired image or video signal without deterioration of an image quality, and can quickly transform a compression format of the image into another format.
