    Abstract: A mobile communications device contains at least two microphones. One microphone is located away from the handset receiver and serves to pick up voice of a near end user of the device for transmission to the other party during a call. Another microphone is located near the handset receiver and serves to pick up acoustic output of the handset receiver (a far end signal). A signal processor measures the frequency response of the receiver. The signal processor performs spectral analysis of the receiver frequency response to determine whether or not the device is being held at the ear of the user. On that basis, the device automatically changes its operating mode, e.g., turns on or off a touch sensitive display screen during the call. Other embodiments are also described.

    Abstract translation: 移动通信设备包含至少两个麦克风。 一个麦克风位于远离手机接收器的位置，用于拾取设备的近端用户的语音，以便在通话过程中传送给对方。 另一个麦克风位于手机接收机附近，用于拾取手机接收机的声输出（远端信号）。 信号处理器测量接收机的频率响应。 信号处理器执行接收机频率响应的频谱分析，以确定设备是否被保持在用户的耳朵处。 在此基础上，设备自动改变其操作模式，例如，在通话期间打开或关闭触敏显示屏幕。 还描述了其它实施例。

    Abstract: An electronic device having one or more sensors is provided. The sensors may include any suitable type of sensor that emits or receives radiation (e.g., light waves) from the environment. The electronic device may include openings through which radiation may reach the sensors while keeping the sensors hidden from view. In some embodiments, the sensors may be placed underneath an opening used for an audio receiver such that radiation is piped to the sensors using a light path or a chamfered surface along the opening. In some embodiments, the sensors may be embedded in a screen such that the radiation emitted by the sensors exits the screen instead of being reflected on the screen. In some embodiments, the sensors may be placed along the periphery of the display, such that access to the sensors is provided via discontinuities in a gasket used to couple the display to the electronic device.

    Abstract translation: 提供具有一个或多个传感器的电子设备。 传感器可以包括从环境发射或接收辐射（例如，光波）的任何合适类型的传感器。 电子设备可以包括开口，通过该开口辐射可以到达传感器，同时保持传感器隐藏在视野之外。 在一些实施例中，传感器可以放置在用于音频接收器的开口下方，使得辐射通过沿着开口的光路或倒角表面被输送到传感器。 在一些实施例中，传感器可以嵌入屏幕中，使得由传感器发射的辐射离开屏幕而不是在屏幕上反射。 在一些实施例中，传感器可以沿着显示器的周边放置，使得通过用于将显示器耦合到电子设备的垫圈中的不连续性来提供对传感器的访问。
