Abstract: A portable electronic device adopts a modular design structure and includes a display screen, a picture taking module and a control module that can be swiveled relative to one another at various angles to provide different operation modes. When in use, due to the swiveling relationship between the display screen, picture taking module and control module, different operation modes can be achieved to meet the requirements of users' different using habits.

Abstract: A TV system capable of recording a multimedia audiovisual program is provided, which comprises a first TV apparatus for receiving a TV audiovisual signal and displaying a corresponding audiovisual program; and a portable second TV apparatus with a built-in storage unit, which is electrically connected to the first TV apparatus and receives a record actuating signal in order to synchronically record the audiovisual program to the storage unit. A user watches the audiovisual program through the second TV apparatus when the second TV apparatus is separated from the first TV apparatus, thereby enhancing the convenience of using the TV apparatus.

Abstract: A method for managing net data of a layout is provided. The method comprises first establishing a net data classification index list in which a net name corresponds to a sub group; comparing a newly added net name with the net data classification index list; classifying the newly added net name to a designated sub group when the newly added net name does not exist in the net data classification index list; establishing an association between the newly added net name and the sub group; and storing the association corresponding to the net name and the sub group in the net data classification index list. Thus the efficiency for managing and utilizing the net data is improved.

Abstract: A method of shifting between viewpoints of layout edit windows includes: adjusting a display multiplier of the edit window to display a first electric element at a first coordinate in the edit window; establishing a first view point shifting command, which corresponds to the display multiplier and the first coordinate; adjusting the display multiplier of the edit window to display a second electric element at a second coordinate in the edit window; establishing a second viewpoint shifting command, which corresponds to the display multiplier and the second coordinate, and performing the first viewpoint shifting command or the second viewpoint shifting command, to display the first electric element or the second electric element in the edit window.

Abstract: A method for facilitating the power/ground wiring in layout is provided, which comprises searching more than one power line or more than one ground line according to the key words of the line names; specifying the power lines correspond to a power layer or the ground lines correspond to a ground layer; setting the power layer or the ground layer to be a line layer to be wired; selecting the line layer to be wired; and indicating the corresponding power lines of the power layer or the corresponding ground lines of the ground layer with special indication effects according to the line layer to be wired, thereby avoiding neglect.

Abstract: A method for verifying line information in a layout and system thereof are provided. The verification method comprises obtaining and arranging a line data to classify the types of the line data; generating a corresponding line information record file after the line data is classified; sending a message appended with the line information record file to a user; confirming the types of the line data once again according to the line information record file by the user; directly modifying the line information record file by the user when it has been confirmed that the line data is wrong; and importing the modified line information record file into the line information database, so as to update the data in the line information database, thereby improving the accuracy of data.

Abstract: A method for indicating differential signal lines in a layout is provided, which comprises searching line groups having similar line names at first; dividing the line groups into a first line and a second line; confirming that the first and second lines are connected to a same circuit element; highlighting the first and second lines, thereby eliminating the trouble in searching differential signal lines.

Abstract: A method for quick naming graphics with the same properties comprises the following steps: selecting a plurality of graphics with the same properties from an operation window, then defining an object name and adding auxiliary symbols behind the object name by using the increment rule to generate a plurality of object names containing the sequentially corresponding auxiliary symbols; and marking the object names containing the respective auxiliary symbols on the respective graphics sequentially and correspondingly. Users may repeat the above steps to continuously select another object name, thereby achieving the quick naming of the graphics.

Abstract: A multimedia playing method and system are proposed. The system at least has a main section and a remote section having a fingerprint identifying function. The main section has a database for storing identification data of multimedia contents, pausing points of the multimedia contents indicating the point at which the contents were previously paused when played and corresponding user identifications. The remote section acquires a fingerprint of a current user as the user identification, the multimedia content to be played and the user's instructions, which are transmitted to the main section. The main section then searches in its database for a pausing point of the multimedia content to be played corresponding the user identification. Then, the multimedia content is played from the pausing point for the particular user.

Abstract: A docking station for notebook computers includes a connection module, a detection module, a connection port and a signal-processing module. When coupling of a notebook computer and the docking station is detected, an activation signal is generated to activate the signal-processing module to process video/audio signals input to the docking station. The processed video/audio signals are output to the notebook computer to enable users to enjoy video/audio programs on the hardware facilities of the notebook computer thereby to expand the function of the docking station.

Abstract: A computer mouse structure for preventing foreign materials from accumulating on an X-axle and a Y-axle in the computer mouse includes two scraper seats located on an inner side of a lower shell of the mouse on one side of the X-axle and the Y-axle opposite to a track ball which is in contact with the X-axle and the Y-axle. Each of the scraper seats has a scraper which is spaced from the axle at a selected gap to remove the foreign materials attached to the axle when the foreign materials reach the scraper during rotation of the axle.
