摘要： A keypad that produces a voltage level indicative of a key pressed and a touch panel that produces a voltage level indicative of a location on the touch panel that has been pressed are both coupled to the input of an analog-to-digital converter (ADC). A processor, coupled to the output of the ADC, reads the ADC output.

摘要： A detection circuit that detects the open and close state of a flip cover of a communications device. The detection circuit includes a resistive network and an analog-to-digital converter (ADC). When the flip cover is in the closed position, the circuit detects a unique resistive value through a set of contacts. This voltage level is converted from an analog signal to a digital signal via the ADC for input into a microprocessor. When the flip cover is in the open position, the contacts are broken, thus, disabling the detection of the unique resistive value. The resulting voltage level is converted from an analog signal to a digital signal via the ADC for input into a microprocessor. Software, programmed within the microprocessor, enables the communications device to operate in the appropriate mode according to the detection of the open/close state of the flip cover.
摘要翻译：一种检测通信设备的翻盖的打开和关闭状态的检测电路。检测电路包括电阻网络和模数转换器（ADC）。当翻盖处于关闭位置时，电路通过一组触点检测出独特的电阻值。该电压电平通过ADC从模拟信号转换为数字信号，以输入微处理器。当翻盖处于打开位置时，触点断开，从而禁止检测唯一的电阻值。所得到的电压电平通过ADC从模拟信号转换为数字信号，以输入微处理器。根据检测到翻盖的打开/关闭状态，在微处理器内编程的软件使通信设备能够以适当的模式工作。

摘要： A flip cover and hinge operate as a rotary switch to select the mode of operation of a communications device. Multiple contacts are located on the sides of the inner surface of the flip cover and a single contact is located on each side of the body of the communications device. Each contact located on the sides of the inner surface of the flip cover represents a different mode of operation for the communications device. As the flip cover rotates from a closure position to its final position as a stand, the mode of operation of the communications device changes as the contact from the body of the communications device connects with one of the contacts on the flip cover. Three modes of operation are presently implemented: the KEYPAD mode, the SMARTPHONE mode, and the SPEAKERPHONE mode.
摘要翻译：翻盖和铰链作为旋转开关操作以选择通信设备的操作模式。多个触点位于翻盖的内表面的侧面上，并且单个触点位于通信设备的主体的每一侧上。位于翻盖内表面侧面的每个触点代表通信设备的不同操作模式。当翻盖从关闭位置旋转到其作为支架的最终位置时，通信设备的操作模式随着通信设备的主体的接触与翻盖上的触点中的一个连接而改变。目前实现了三种操作模式：键盘模式，SMARTPHONE模式和SPEAKERPHONE模式。
