Abstract: Systems and methods are provided for determining a light intensity level of emitted light from an illuminator of a display device and the ambient light surrounding the display device such that, for example, the display device may compensate for performance variations of the illuminator over time.

Abstract: Methods and systems are described for proximity condition detection of a recovery from sensor proximity saturation caused by water immersion of a user device. The device transmits data at a first transmit power level using an antenna. In one system, a proximity condition checker determines that a first proximity sensor and a second proximity sensor are saturated in an unknown state after a power event where the saturation caused at least in part by the presence of water in proximity to the first proximity sensor and the second proximity sensor. The proximity condition checker determines that 1) both the first proximity sensor and the second proximity sensor are no longer saturated and 2) water is no longer in proximity to the first proximity sensor and the second proximity sensor. In response, the user device can transmit data at an increased second transmit power level using the antenna.

CPC classification number: G06K9/00604
Abstract: An electronic device including an illuminator and a camera configured for performing iris recognition while the user holds the device. The lens of the camera comprises four molded plastic elements with eight aspheric surfaces at a total thickness of only 3.4 mm that provides a mildly distorted image 1.2 mm across. The relative aperture is 3.5 with a fixed focal distance, providing a depth-of-field spanning a fixed focus region of at least 10 cm in depth that is 25 to 35 cm (centimeters) from the eye. The illuminator comprises a near-IR LED in a Cassegrain telescope configuration for efficient directing of flux toward the eye, thereby conserving device volume and electric energy use.

Abstract: The techniques described herein mitigate the effects of electromagnetic interference, caused by the sending or receiving of data, on a proximity sensor of an electronic device. In some instances, capacitance values measured by the proximity sensor may be inaccurate during times at which the electronic device is sending or receiving data. To mitigate this effect, the techniques take into account the recurrent time slot(s) at which the electronic device is scheduled to send or receive data, and then disregards the capacitance values measured by the proximity sensor at these times.

Abstract: A decision engine executing on an electronic device may determine, using sensor data captured by multiple sensors of the device, whether a user is present in an environment that includes the device. If the user is determined to be present in the environment, the device may transition from a first state to a second state. The first state may be a first power state of the device in which the device is powered off or an idle or dormant state in which the device is powered on but a display of the device is powered off. Correspondingly, the second state may be a second power state of the device in which the device and the display are powered on and content is being rendered on the display. If the decision engine cannot make a determination based on the sensor data, a context engine may adjudicate the user presence determination.
