    • A resistive input pad that can be used as a keypad and/or a touchpad comprises a top surface layer with a plurality of resistive sensing pads disposed below the top surface layer. The top surface extends continuous over the surface of the input pad. The number of resistive sensing pads does not need to match the number of keys that are distinguishable by the keypad print on the top surface layer. The grid formed by the resistive sensing pads can be more or less fine than the grid formed by the keys as defined by the keypad print. With a sufficiently fine array of resistive sensing pads the input pad can be used for navigational and drawing purposes similar to a conventional touchpad.
    • 可用作键盘和/或触摸板的电阻式输入焊盘包括具有设置在顶表面层下方的多个电阻感测焊盘的顶表面层。 顶表面在输入垫的表面上连续延伸。 电阻感测垫的数量不需要与顶表面层上的键盘印刷区分的键的数量相匹配。 由电阻感测焊盘形成的栅格可以或多或少地比由键盘印刷所限定的由键形成的栅格精细化。 利用足够精细的电阻感测垫阵列,输入垫可用于类似于常规触摸板的导航和绘图目的。
