摘要： The present invention relates to a method and apparatus for generating driver signals of SAW touch panel. The method includes the steps of: sending a trigger signal continuously by referring to an input signal, wherein the trigger signal is sent when the input signal is within a predetermined range; generating a surface acoustic wave according to the trigger signal; transmitting the surface acoustic wave to at least one transducer via a touch surface; and detecting the input signal via at least one transducer. Moreover, the input signal is kept on a predetermined level when the surface acoustic wave has not been received by the transducer and when a noise signal from circuits outside the transducer has not been added in the input signal. The predetermined level is within the predetermined range. The sensing accuracy of the SAW touch panel can be enhanced because the noise signal has less effect on the driver signals.

摘要： An apparatus for detecting a position by infrared rays is disclosed. The apparatus includes a plurality of IR sources, a plurality of receivers and a processor electrically coupled to the receivers. The IR sources and the receivers are interlacedly configured along a frame. The IR sources emit IR signals in at least two dimensions, and the IR sources in each dimension comprise two sets of IR signals running contrarily in direction. The receivers receive the IR signals from the corresponding IR sources. Even if the IR signals in one direction of one dimension are subject to interference, the IR signals in the other direction of the dimension can still be measured by the corresponding receivers. When at least one object is set in at least one position within the frame, the processor determines the position according to the coordinates of the receivers and strength variations of the received IR signals.

摘要： A device and method for detecting connections of a 4- or 5-terminal resistive touch panel are disclosed. The device includes five terminals and a detecting unit. When the five terminals are connected to the touch panel, the detecting unit provides a high potential and a low potential to first and last of the five terminals, respectively, thereby determining whether the touch panel is a 4- or 5-terminal resistive touch panel by determining if there is a closed circuit between the two terminals.
