An electronic device may include an infrared light source and an infrared image sensor to enable infrared beacon functionality. In a location sharing scenario, a first electronic device may use the infrared light source to emit infrared light and serve as an infrared beacon. A second electronic device may use the infrared image sensor to detect the infrared beacon and identify the location of the first electronic device. The infrared image sensor that is used to detect the infrared beacon may also serve as a time-of-flight sensor for a light detection and ranging (LiDAR) module. The second electronic device (that detects the infrared beacon) may provide output such as visual, audio, and/or haptic output to inform a user of the location of the infrared beacon.

An acoustic imaging system coupled to an acoustic medium to define an imaging surface. The acoustic imaging system includes an array of piezoelectric acoustic transducers formed at least in part from a thin-film piezoelectric material, such as PVDF. The array is coupled to the acoustic medium opposite the imaging surface and formed using a thin-film manufacturing process over an application-specific integrated circuit that, in turn, is configured to leverage on or more beamforming scan operations to drive the array of piezoelectric actuators to generate an image of an object at least partially wetting to the imaging surface.

Ultrasonic force detection systems and methods can be based on propagation of ultrasonic waves in a user's body (e.g., in a user's digit). An amount of force can be determined using time-of-flight (TOF) techniques of one or more ultrasonic waves propagating in the user's body. In some examples, an electronic device including a transducer can be coupled to a digit, and can transmit ultrasonic waves into the digit. As the wave propagates through the thickness of the digit, a reflection of at least a portion of the transmitted wave can occur due to the bone and/or due to reaching the opposite side of the digit (e.g., finger pad). One or more reflections can be measured to determine the amount of force.
