    Abstract: A user identification based control system includes a time of flight ranging sensor configured to sense a distance to a person, where the time of flight ranging sensor is positioned so the sensed distance is a function of a height of the person. Processing circuitry is coupled to the time of flight ranging sensor and configured to identify the person based upon sensed distance and to generate control signals to control peripheral components based upon the identity of the person. The time of flight ranging sensor may also be used to sense speed of the person for identification purposes. In general, the time of flight ranging sensor is positioned a known height over a surface on which the person is present, such as in the doorway or on a ceiling of a room.

    Abstract: The present disclosure provides a device and method for depth sensing by utilizing the combination of a ranging sensor and an image sensor. The ranging sensor can accurately detect distance measurement from an object. The image sensor can take images with high resolution of the object. By combining each sensor data from the ranging sensor and the image sensor, accurate depth information with high resolution of the object may be obtained. A structured light having patterned shapes are used in conjunction with the ranging sensor to receive reflected patterned shapes of the object. These reflected patterned shapes are used to analyze distance measurements associated with the specific patterned shapes. These distance measurements from both the ranging sensor and the image sensor is aligned and combined to generate an accurate depth map with high resolution using a processor of an electronic device including the ranging sensor and the image sensor.

    Abstract: A time of flight range detection device includes a laser configured to transmit an optical pulse into an image scene, a return single-photon avalanche diode (SPAD) array, a reference SPAD array, a range detection circuit coupled to the return SPAD array and the reference SPAD array, and a laser driver circuit. The range detection circuit in operation determines a distance to an object based on signals from the return SPAD array and the reference SPAD array. The laser driver circuit in operation varies an output power level of the laser in response to the determined distance to the object.
