Abstract
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.
