20090160514 | Chip structure capable of smoothing slope of signal during conversation - The present invention discloses a chip structure capable of smoothing slope of signal during conversion. And the chip structure is suitable for a DC motor which is embedded in a portable electronic device. The DC motor is for adjusting the focal distance of a digital camera which is installed within the portable electronic device. The chip structure comprises an input terminal, a first converter, a control unit, a second converter, an amplifier circuit and an output terminal. The input terminal is for receiving a first digital signal. The first converter is for converting the first digital signal into an analog signal. The control unit is for elongating the transform time of the analog signal. The amplifier circuit is for amplifying the elongated analog signal. The second converter is for converting the elongated analog signal into a second digital signal. And the output terminal outputs the second digital signal. | 06-25-2009 |
20090085888 | Resistive multi-touch panel and detecting method thereof - The present invention provides a resistive multi-touch panel and its method that comprises a first touch panel module, a second touch panel module, at least one touch sensing device and at least one coordinate acquiring device. Therein, the first touch panel module includes a plurality of first planar resistors independently arranged. The second touch panel module includes a plurality of second planar resistors, also independently arranged. The second touch panel module is positioned below the first touch panel module while an arrangement direction of the second planar resistors differs from an arrangement direction of the first second planar resistors. Thereupon, the resistive multi-touch panel employs the plurality of first planar resistors and the plurality of second planar resistors to achieve multi-touch effect to overcome the defect of the conventional resistive touch panel that merely allows the single-touch input at a time. | 04-02-2009 |
