    • There is described portable electronic devices having one or more proximity sensors with adaptive capabilities that can help reduce power consumption. The proximity sensors of the portable electronic device in accordance with the present invention may be adjusted to operate in multiple and/or different modes. These modes are environmentally and contextually driven. An adaptive sensor is dynamically adjusted based on different criteria. In particular, adjustments are based on correlations of input signals from one or more sensors of the device, data signals received from the device's processor and/or external data signals received from an external source, which provide characterization values of environmental, contextual and/or ambient light characteristics. Adjustments are made to pulse power to affect the range of the sensor, pulse frequency, filtering of noise of the sensor input signal to attenuate interference and the spectrum of a proximity detector.

    • Disclosed in a wearable electronic device including an optical keypad supported by a keypad housing. The optical keypad may include a plurality of keys disposed along the keypad housing, and a plurality of illumination sources and optical receivers with a corresponding illumination source and optical receiver for each of the plurality of keys. The keypad signal interface may be limited to three connections, to provide a connection for power, a connection for ground, and a connection for data between the keypad housing and the main housing. The electronic device may also include at least one optical receiver configured to be optically coupled to at least one of the plurality of illumination sources, and configured to convert a received optical signal representing data into an electrical signal representing data. The illumination sources may provide optical signals during key presses, and may in addition provide key illumination for unpressed keys.
    • 公开在可佩带的电子设备中,包括由键盘壳体支撑的光学键盘。 光学键盘可以包括沿着键盘壳体设置的多个键,以及多个照明源和具有用于多个键中的每一个的对应的照明源和光学接收器的光学接收器。 键盘信号接口可以限于三个连接,以提供用于电源的连接,用于接地的连接以及用于键盘壳体和主壳体之间的数据的连接。 电子设备还可以包括至少一个光学接收器,其被配置为光耦合到多个照明源中的至少一个照明源,并且被配置为将表示数据的接收的光信号转换为表示数据的电信号。 照明源可以在按键期间提供光信号,并且还可以为未按下的按键提供关键照明。
