    • A user interface (210) includes an RC circuit (213). The RC circuit (213) includes a variable capacitance. The variable capacitance is produced by a sensing member (310) in cooperation with a user's finger (311). When a user makes a selection with the user interface (210), the user places a finger (311) in close proximity and in a facing relationship to a section, or discrete surface (320, 322, 324), of the sensing member (310). The discrete surfaces (320, 322, 324) can correspond to keys of a keypad (138) or to directions of a directional button (1030), for example. The time constant of the RC circuit (213) varies according to which discrete surface (320, 322, 324) is determining the capacitance of the RC circuit (213). A controller (118) determines the user's selection based on the time constant of the RC circuit (213).
    • 用户接口(210)包括RC电路(213)。 RC电路(213)包括可变电容。 可变电容由与用户的手指(311)协作的感测构件(310)产生。 当用户使用用户界面(210)进行选择时,用户将手指(311)放置在感测构件的部分或离散表面(320,322,324)的紧密接近处和面对的关系中 310)。 离散表面(320,322,324)可以对应于键盘(138)的键或方向按钮(1030)的方向。 RC电路(213)的时间常数根据哪个离散表面(320,322,324)确定RC电路(213)的电容而变化。 控制器(118)基于RC电路(213)的时间常数确定用户的选择。

    • A bus interface and corresponding method is provided for conveying communication signals supporting multiple modes, where at least two of the modes have distinct operational communication signal levels. The bus interface is adapted to convert the communication signals between communication signals having distinct signal levels, and communication signals having compatible signal levels. Where in at least some instances, the conveyed communication signals are converted from communication signals having distinct signal levels to communication signals having compatible signal levels, and then back to communication signals having distinct signal levels, after the communication signals having compatible signal levels are transmitted and received via one or more associated communication paths.
