  • Patent number: 7879712
    Abstract: A method for patterning polycrystalline indium tin oxide by using a Gaussian laser beam focused on an amorphous indium tin oxide layer is disclosed to pattern the non-crystalline amorphous indium tin oxide layer and transfer part of the amorphous indium tin oxide layer into polycrystalline indium tin oxide while the remaining amorphous indium tin oxide layer is etched due to etching selectivity of an etching solution. The method comprises: providing a substrate with an amorphous indium tin oxide layer thereon on a carrier; transferring the amorphous indium tin oxide layer in a predetermined area into a polycrystalline indium tin oxide layer by emitting a Gaussian laser beam focused on the amorphous indium tin oxide layer in the predetermined area; and removing the remaining amorphous indium tin oxide layer on the substrate by an etching solution to form a patterned polycrystalline indium tin oxide layer.

  • Publication number: 20090316874
    Abstract: A communication device having an answering system sets task names, task schedule times of one or more tasks, predetermined ring settings when an incoming call is received during one of the task schedule times, and setting predetermined recorded message. The answering system is configured for determining if the incoming call is received during one of the task schedule times, ringing using the predetermined ring setting if the incoming call is received during one of the task schedule times, replying to the incoming call with the predetermined recorded message if the incoming call is received during one of the task schedule times and if the incoming call has not been answered.

  • Publication number: 20090303840
    Abstract: The present invention provides a method for removing micro-debris generated in a laser machining process operated on machined object and device of the same. The machined object is placed on a movable machining platform within a machining range and machined at a particular machining location. By disposing an acoustic wave generator and a reflector part, or by disposing a plurality of acoustic wave generators, at least two standing waves extending across the machining range and two standing wave nodes are generated. The micro-debris generated from the laser machining process is moved away by the standing waves to concentrate at the standing wave nodes, and subsequently removed from the standing wave nodes.

  • Publication number: 20040126011
    Abstract: An image scanning method, applied to a document, performs a preliminary scanning operation to distinguish the document into areas uniformly containing a same color level and scanned areas containing different color levels. An image scanning sequence is subsequently performed, during which an area of the document to be scanned is skipped if it has been determined as an area uniformly having a same color level. A color code value corresponding to the uniform color level of this area is consequently stored in a corresponding memory zone. The above image scanning sequence is executed until the scanning of the document is completed.

  • Publication number: 20040085591
    Abstract: A method for reducing image noise is provided. The procedure of the method is provided in the following steps. First, the color level scale of a scanned image of a document is reduced by a plurality of bits in order to subtract a noise level from the scanned image. Then the color level scales of all pixels of the image are recombined by a halftone pattern method in order to recover the color level scales. Finally the missing codes of the image are filled out by bit enhance method. Because of the color level scales of the proceeding image are not reduced, the scanned image quality does not be blurred by the method. Because the method does not minimize the color level of the proceeding image, the image noise can be reduced without blurring the scanned image and the quality of the image can be increased after the process thereof. And because each color level of the pixel in the image is subtracted by a noise level, some of the bits are removed and the capacity of the image file is decreased.

  • Publication number: 20040008377
    Abstract: A method for adding text to an image applied to an image scanner including at least the following steps: first, pre-scan a document and acquire a source image accordingly; next, input the content of the text to be added to the source image such that the source image becomes a pre-set image; last, perform document-scanning according to the pre-set image to acquire a scanned image. Of which, the text content can be located at any position of the pre-set image, whereas the source image and the pre-set image can be displayed via a display interface. In practice, the display interface can be a display window.

  • Publication number: 20030083835
    Abstract: An image-autocrop method is employed to calculate and calibrate the image data of a quadrangle of a target object scanned by an image-input device so as to acquire four optimum vertexes for defining a better image-autocrop field. This method is applied to load firstly the coordinates of four vertexes scanned, then calculate and calibrate them to obtain an optimum rectangular image scope.
