摘要： There is disclosed a keypad apparatus and a method for determining the status of a keypad apparatus. In one embodiment, the keypad apparatus includes a keypad having a plurality of keys and a keypad matrix associated with the keypad and having a switch. The keypad apparatus also includes a cover moveable between an open and a closed position. The keypad apparatus still further includes a means for engaging that cooperates with and allows the switch to provide a status indicating a position of the cover.

摘要： In a preferred embodiment, the invention is a mobile communication device having a digital signal processor (DSP), a speaker output node, a local audio source, and an analog front-end (AFE), wherein: (1) the DSP receives a first audio signal corresponding to sound captured by a microphone near a user of the device, (2) if the device is operating in a call mode, the DSP derives a background noise signal from the first audio signal, for subtraction from the first audio signal before transmission to the AFE, and (3) if the device is operating in a non-call mode, then the DSP (i) generates a speaker output signal which substantially corresponds to the first audio signal subtracted from a local audio signal provided by the local audio source and (ii) provides the speaker output signal to a speaker via the speaker output node.
摘要翻译：在优选实施例中，本发明是具有数字信号处理器（DSP），扬声器输出节点，本地音频源和模拟前端（AFE）的移动通信设备，其中：（1）DSP接收对应于由设备用户附近的麦克风捕获的声音的第一音频信号，（2）如果设备在呼叫模式下操作，则DSP从第一音频信号中导出背景噪声信号，以从第一音频信号中减去在发送到AFE之前，以及（3）如果设备在非呼叫模式下操作，则DSP（i）产生一个扬声器输出信号，该扬声器输出信号基本上对应于从由本地音频信号提供的本地音频信号中减去的第一音频信号本地音频源，并且（ii）经扬声器输出节点向扬声器提供扬声器输出信号。

摘要： A system for, and method of, obscuring ambient noise. In one embodiment, the system includes: (1) a background sound generator, (2) a mixer coupled to the background sound generator and (3) a user interface, coupled to the mixer, that, upon a user command, causes the mixer to mix an output of the background sound generator with a transmitted signal. The background sound may be music, white noise, colored noise, out-of-phase ambient noise, simulated alternative ambient noise or any other suitable background sound. The system may be associated with a wireless handset, a wireline handset, central office equipment or any other suitable location or equipment.
