    Abstract: A capacitive touch device and a sensing method thereof are disclosed. The capacitive touch device includes a touch panel, at least one touch detection unit and a processing unit. The touch detection unit scans the touch panel, obtains an N-bit sensed data and compresses the N-bit sensed data to an L-bit sensed data. The processing unit receives the L-bit sensed data, decompresses the L-bit sensed data to the N-bit sensed data and calculates a coordinate of a touch according to the N-bit sensed data. The present invention is capable of decreasing the time for transmitting the sensed data, the power consumption and the requirements for the memory capacity of the touch detection unit and the memory capacity of the processing unit.

    Abstract: A method for motion pixel detection with adaptive thresholds, according to the global motion information among the reference video fields, so as to correctly evaluate whether a missing pixel is in a static region or a non-static region, thereby reconstructing the missing pixel by an inter-field interpolation process or an intra-field interpolation process. If the amount of motion among the reference fields is large, there is high motion information among the reference fields, so the threshold is set to be small; if the amount is small, there is less motion information between the reference fields, and so the threshold should be set to be large.

    Abstract: For a plurality of logic integrated circuits, initial value vectors associated with flip-flops are retrieved from each of corresponding scan chain sets. The initial value vectors of the same corresponding scan chain set are compared with each other so as to identify elements with fixed values in the initial value vectors. When the total number of the elements with fixed values reaches a predetermined percentage, the elements having fixed values are selected as a golden pattern of the corresponding scan chain set. During the testing, an initial value vector of a scan chain of a logic integrated circuit to be tested is compared with the golden pattern associated with the scan chain, so as to determine whether a faulty flip-flop exists in the scan chain of the logic integrated circuit to be tested.

    Abstract: A collision detection method for a multiple access communication system is disclosed. By using the error term of a time-domain equalized signal as a detection source, an operation on the error term can be performed to determine whether collision occurs. For example, the mean square error and/or maximum value of the real part and/or imaginary part of the error term can be calculated or selected to distinguish the collision and non-collision situations. A collision detection apparatus for a multiple access communication system is also disclosed. The collision detection apparatus utilizes an existent adaptive equalizer and signal processing device for obtaining received information data bits to obtain the error term. The error term is further processed by a mean-square-error or maximum-absolute-value operator to determine the collision status.

    Abstract: This invention provides a dual damascene structure having capacitors. Before the thin-film capacitor is formed, the underlie interconnections are fabricated with Cu metal by damascene processes. The capacitor is formed by depositing a first metal layer, an insulator and a second metal layer. Then, the stacked layers are subjected to two masking and etching processes to form the thin-film capacitor and the metal wire. After forming the capacitor, the upper interconnections are fabricated with Cu metal by damascene processes.
