Temperature measurement via ultrasonic sensor

Some disclosed methods involve capturing a first ultrasound signal corresponding to a reflection from a cover/air interface of a device including an ultrasound sensor system, and determining one or more first ultrasound signal parameters of the first ultrasound signal. Some methods involve capturing a second ultrasound signal corresponding to a reflection from the cap/target interface, and determining one or more second ultrasound signal parameters of the second ultrasound signal. Some methods involve estimating a target object temperature based at least in part on one or more first ultrasound signal parameters, one or more second ultrasound signal parameters, and an ultrasound sensor system temperature. Some disclosed methods involve receiving ultrasound sensor system temperature data indicative of a temperature of an ultrasound sensor system and calibrating the ultrasound sensor system as a function of the temperature. 所公开的一些方法涉及捕获与来自包括超声传感器系统的装置的盖/空气界面的反射相对应的第一超声信号，以及确定第一超声信号的一个或多个第一超声信号参数。一些方法涉及捕获与来自盖/目标界
