Abstract: The invention is to provide an opening device with self-flipping lid-body, which includes a shell body, a lid body, a pressing apparatus, and an opening apparatus. The shell body has an accommodation space. One side of the shell body is arranged with a groove hole. The lid body is connected to the shell body by a pivoting manner. The lid body has a wedging hook in corresponding to the groove hole. The lid body chooses that the wedging hook be connected with the groove hole to seal the accommodation space, or choose that the wedging hook be separated from the groove hole to open the accommodation space. The pressing apparatus is connected to the shell body and has a pivoting axis that be activated by touching off. The opening apparatus is connected to the pressing apparatus and has a convex block in corresponding to the groove hole. The wedging hook is separated from the groove hole by making the convex block abutted and contacted with the wedging hook.

Abstract: The invention, an improved device and method for the pointer system of a digitizer tablet, is to repetitiously emit signals sequentially from a specific set of inductive loop when the position pointed by the wireless pointer device is located within a range formed by this specific set of inductive loop induced most intensively during a locally scanning process. After a transient energy storage of the wireless pointer device, corresponding resonant signals are emitted out and are received sequentially by several sets of inductive loop located on the digitizer tablet in the neighborhood of this specific set of inductive loop and, by these signals, the wireless pointer device's coordinate position on the digitizer tablet is calculated out relatively.

Abstract: A 4-4 distribution antenna layout and a five-stage coordinate positioning method of electromagnetic induction systems being provided by the present invention is disclosed. The 4-4 distribution antenna layout of the present invention divides antenna circuitries into x-axis and y-axis groups. The antenna circuitries within the same group are in equal distance displacements and in the same direction, which further comprise a plurality of antenna loops. The formation of each antenna loop comprises a dense multiple duplicate self-looping method. Moreover, the five-stage coordinate positioning method of electromagnetic induction systems comprising, first, carrying out a first procedure to confirm any signal with voltage amplitude greater than a standard minimum signal recognition value. Second, carrying out a second procedure to confirm signal existence of the previous scan as well as to confirm the nearest antenna loop to the transmission source. Third, carrying out a third procedure to obtain coordinate values.

Abstract: The layout of multi-antenna loops in this invention comprises: a plurality of antenna loops, wherein one terminal of each antenna loop is electrically coupled with an antenna switch and the other terminal is electrically connected to a ground wire. All antenna loops are symmetrical antenna loops each of which contains a plurality of n-shaped sections to form sawtooth-shaped regions and compound into a plurality of dummy closed regions. If the symmetrical antenna loops are in-phase state, the plurality of sawtooth-shaped regions consist of the plurality of n-shaped sections with the non-interlacing method; if the symmetrical antenna loops are oppositephase state, the plurality of sawtooth-shaped regions consist of the n-shaped sections with the interlacing method.

Abstract: A method of measuring tablet. Firstly, a tables is provided that has a processing device area, a ground point and numerous separate conductive lines, each conductive line has a first terminal electrically connected with the processing device area and a second terminal electrically connected with the ground point, and each conductive line has a switch near to the second terminal. Next, these switches are turned off so as to let the processing device area be electrically separated from the ground point. Then, a testing process is performed on each conductive line in sequence, the testing process measures the connection between each conductive line and other conductive lines to decide whether a short has happened.

Abstract: An liquid crystal display (LCD) device comprises: a control circuit for providing video signals of a plurality of pictures in sequence; a voltage-level shift circuit for shifting and applying different voltage levels on crystal molecules in the LCD device to twist them to different orientations in order to create different rotary polarization effects; and a light-guiding filter layer for filtering and scattering light in different orientations to make it possible for viewing pictures from various angles. The light-guiding filter layer may be placed in front of or behind a color-filter layer or combined with the latter to form a unitary layer.
