    • A method and apparatus is provided for adjusting the gain imparted to a signal by an audio transducer such as a microphone and/or a speaker, which is employed by an electronic device having a multi-touch screen user input. The method begins when pressure applied to the multi-touch screen by a user is detected. The pressure is detected while the user is providing or receiving audible signals to or from, respectively, the audio transducer. Next, the user is identified based on a pre-established user profile that identifies the user based on a pressure profile that is obtained by the multi-touch screen. The pressure profile represents at least a contour of a portion the user's head such as the user's ear, cheek or the like. Once the user has been identified, pre-established user-selectable settings associated with the identified user are retrieved from memory. Finally, the gain imparted to the signal by the audio transducer is adjusted upward or downward based at least in part on the detected pressure and in accordance with the user-selectable settings.
    • 提供了一种方法和装置,用于通过诸如麦克风和/或扬声器之类的音频换能器来调节由具有多点触摸屏用户输入的电子设备使用的增益。 当检测到由用户施加到多点触摸屏的压力时,该方法开始。 当使用者分别向音频传感器提供或接收声音信号时,检测到压力。 接下来,基于基于由多点触摸屏获得的压力分布来识别用户的预先建立的用户简档识别用户。 压力分布至少表示用户头部的诸如用户的耳朵,脸颊等的部分的轮廓。 一旦识别了用户,就从存储器中检索与所识别的用户相关联的预先建立的用户可选设置。 最后,至少部分地基于检测到的压力并且根据用户可选择的设置,由音频传感器赋予信号的增益被向上或向下调整。

    • A portable communication device (150) can include a transceiver (74) and a processor (76) coupled to the transceiver. The processor can be programmed to monitor at least one neighboring cell among a plurality of cells for a load condition on the at least one neighboring cell, monitor the at least one neighboring cell for a service capability and discontinue the monitoring of the at least one neighboring cell if a desired service capability fails to match the service capability of the at least one neighboring cell or if the load condition fails to meet a predetermined load condition. The processor can be further programmed to monitor the at least one neighboring cell for a signal quality indication and to discontinue the monitoring of the at least one neighboring cell if the signal quality indication falls below a predetermined threshold.

    • A radio device 100 includes: a speaker 130, which outputs audio signals, a microphone 129 that detects and receives audible sounds within the surroundings of the radio device; an audio volume/characteristic adjusting mechanism 125, which selectively increases and decreases the volume level or other audio characteristics of the audio signal outputted from the radio device based on a user input; and means (150) for dynamically adjusting the audio volume and other audio characteristics of the audio signal based on a stored relational mapping, which links a user adjustment of the audio volume/characteristic to a specific audible sound previously detected within the environment by the microphone 129, such that future detection of the audible sound by the microphone 129 triggers the dynamically adjusting of the audio volume (320) and other audio characteristics.
    • 无线电设备100包括:扬声器130,其输出音频信号;麦克风129,其在无线电设备的周围环境中检测和接收可听见的声音; 音频/特性调整机构125,其基于用户输入选择性地增加和减少从无线电设备输出的音频信号的音量或其他音频特性; 以及用于基于所存储的关系映射来动态地调整音频信号的音频音量和其他音频特性的装置(150),所述关系映射将音频/特性的用户调整与由环境中先前在环境中检测到的特定可听见的声音相关联 129,使得由麦克风129对未听到的声音的检测触发音频音量(320)和其它音频特性的动态调整。
