Abstract: In accordance with embodiments, methods and systems for utilizing multiple threshold checkers are provided. A range sensor collects measurement data. The range sensor examines the measurement data based on multiple threshold checkers to determine satisfaction of a trigger condition. In response to the satisfaction of the trigger condition, the range sensor provides the measurement data to a host computing device of the range sensor.

Abstract: A device includes a time-of-flight ranging sensor configured to transmit optical pulse signals and to receive return optical pulse signals. The time-of-flight ranging sensor processes the return optical pulse signals to sense distances to a plurality of objects and to generate a confidence value indicating whether one of the plurality of objects has a highly reflective surface. The time-of-flight sensor generates a range estimation signal including a plurality of sensed distances and the confidence value. The image capture device includes autofocusing circuitry coupled to the time-of-flight sensor to receive the range estimation signal and configured to control focusing based upon the sensed distances responsive to the confidence value indicating none of the plurality of objects has a highly reflective surface. The autofocusing circuitry controls focusing independent of the sensed distances responsive to the confidence value indicating one of the objects has a highly reflective surface.
