    • Connection establishing management methods for traversing network address translation (NAT) routers and firewalls between network terminal devices to establish a connection channel therebetween for use in a network system including at least first, second and third network terminal devices and a traversal server are disclosed. First, when traversal server receives a call request of first and second network terminal devices, network topology levels of first and second network terminal devices are detected to detect whether first and second network terminal devices are located behind NAT router and/or firewall. Then, one of first and second network terminal devices or third network terminal device is selected according to the detection result such that selected network terminal device acted as proxy server for the traversal server to establish a connection channel corresponding to call request between first and second network terminal devices.

    • A sensing method and circuit for a capacitive touch panel sense the capacitance variation of a lateral capacitor formed at the intersection of two traces of the capacitive touch panel, to distinguish a real point from a ghost point. A sensing cycle includes two non-overlapping clock phases. In the first clock phase, the voltages across the lateral capacitor and across a sensing capacitor are set. In the second clock phase, the voltage at a first terminal of the lateral capacitor is changed, and a second terminal of the lateral capacitor is connected to a first terminal of the sensing capacitor, causing a voltage variation at a second terminal of the sensing capacitor. This voltage variation is used to determine whether the intersection is touched. The sensing method and circuit reflect the status of the lateral capacitor in real-time and prevent the location of the touch point from being misjudged.
    • 用于电容式触摸屏的感测方法和电路检测形成在电容式触摸面板的两个迹线的交点处形成的横向电容器的电容变化,以将真实点与虚像点区分开。 感测周期包括两个不重叠的时钟相位。 在第一个时钟相位中,设置横向电容器两端的感测电容器两端的电压。 在第二时钟相位中,横向电容器的第一端子处的电压改变,并且横向电容器的第二端子连接到感测电容器的第一端子,导致感测电容器的第二端子处的电压变化 。 该电压变化用于确定交点是否被触摸。 感测方式和电路实时反映横向电容器的状态,防止接触点的位置误判。
