Abstract: A method for video processing which provides a scaled image using two different clock frequencies is provided. The method receives source pixel data using a first clock signal and scales the source pixel data to destination pixel data. After that, the destination pixel data is provided using a second clock signal having a second clock frequency and a third clock signal having a third clock frequency during blanking period and active period, respectively.

Abstract: A method for accessing a single port memory is provided. A single port memory is used as a line buffer and divided into a plurality of memory blocks. The line buffer data is written into or read out from these memory blocks by turns with a special sequence corresponding to the operation mode; for example, a normal mode or a PLM mode. Therefore, the line buffer data can be written into or read out from the line buffer at the same time, and the size and cost of integrated circuit can be reduced.

Abstract: The present invention relates to an instrument and method of aligning a collimator. The instrument includes a frame base, a clamp, a first axis stage, a second axis stage, and a rack. A ferrule grasping a fiber therein is inserted in a glass tube, and the glass tube is secured to the frame base by the clamp. A pinion is fixedly mounted on one end of a GRIN lens, which is inserted in the glass tube, and engaged with the rack. The first axis stage moves the GRIN lens along the cylindrical axis of the glass tube, and the second axis stage rotates the GRIN lens around the cylindrical axis of the glass tube. When a light beam emitted from the collimator reaches the maximum intensity, the instrument of the invention accomplishes the alignment of the collimator.

Abstract: A method is designed to adjust the distance between the central axes of two ocular lenses of an optical instrument. The method involves the use of a link mechanism to actuate two movable prisms and the two ocular lenses of the optical instrument to move respectively along a base surface such that the optical axes of effective diameters of the two movable prisms are coaxial with the optical axes of the corresponding ocular lenses.

Abstract: A movable fish net buoy top, having the framework of a buoy top in association with a grid port which can be drawn up by 105 degrees, and pushed down by 75 degrees, so structured that as the top is laid on the surface of water the grid port on either side thereof will, owing to water buoyancy, be pushed up in bearing against a mortise joint catch furnished on top of the strut. When the buoy top is taken off the water surface, a mortise joint catch furnished at the bottom of the strut is deflected by 90 degrees, so as to prevent the grid port from moving downward toward either side due to gravitation, thereby preventing it from opening. To pour out the catch entrapped in the fish net, the mortise joint on top of the buoy top is turned to a setting in parallel with the surface level of the framework, and reverse the framework of the buoy top, so as to bring the grid port to open downwards along either side, so that the catch can be poured out, conveniently and effectively.
