A method for operating an electronic device includes while a display is in low power mode, detecting based on data collected by a time of flight (ToF) sensor, a movable object within a field of view of the electronic device; in response to the detecting initiating a period of detection having a plurality of frames, the period of detection being a time period over which a distance value indicative of a distance between the movable object and the display is detected; for each of the plurality of frames, changing the distance value to reflect whether the movable object is moving near or further from the electronic device; detecting that the distance value after the period of detection is less than a threshold distance value indicative of the movable object approaching the display; if the distance value is less than the threshold distance value, waking up the display.

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.

Multiple threshold checkers for specific applications and FFT based breathing detection for presence

An embodiment device includes an optical source configured to transmit an optical pulse and an optical sensor configured to receive a reflection of the optical pulse. The device further includes a processor configured to determine a parameter based on the reflection, the parameter indicative of a distance between the device and a target; and a controller configured to generate a first control signal based on the parameter, the first control signal being configured to control an operation of the optical source.

Device, system, and method for detecting human presence

An autofocus method determines that a ranging device of a digital camera has failed in an attempt to provide a distance estimation. The ranging device provides one or more parameters indicating conditions related to the failure of the ranging device to provide the distance estimation. An autofocus sequence based on the one or more parameters is then performed.
