  • Method for using touch signals and a touch unit
    Patent number: 7633300
    Abstract: A method for evaluating touch signals on a touch unit which has two resistance foils (1, 2). The current (IX, IY) resulting from applying a given measurement voltage (UX, UY) to at least one of the resistance foils (1, 2) is measured and stored as a desired current value (IXS, IYS). Especially after the presence of at least one touch has been confirmed, the actual current (IX<IY) flowing in the other resistance foil (1, 2) is measured when the test voltage is again applied to at least one of the resistance foils (1, 2), and it is compared with the previously established desired current value (IXS, IYS) for this resistance foil (1, 2). In the event that the actual current (IX, IY) measured in the at least one resistance foil (1, 2) exceeds the desired current value (IXS, IYS), it is judged that a double touch occurred (FIG. 8).
