Abstract: An apparatus may include a platen, a light source system and an ultrasonic receiver system. The platen may be configured to separate one or more received arterial ultrasonic waves generated by blood in an artery, by an arterial wall, or by a combination thereof, from one or more other types of received ultrasonic waves. The platen may have an outer surface with an acoustic impedance that is configured to approximate the acoustic impedance of human skin. The outer surface of the platen may be configured to conform to a surface of the human skin. The apparatus may include a noise reduction system. The light source system may include at least one multi-junction laser diode. The apparatus may include a mirror layer residing between the ultrasonic receiver system and the platen.

Abstract: Methods, devices and systems for providing extended reality effects are disclosed. In some examples, a control system may control a structure to provide extended reality effects and also may control an ultrasound-based haptic system to create haptic effects via transmitted ultrasonic waves. The ultrasound-based haptic system may include one or more arrays of ultrasonic transducers, such as piezoelectric micromachined ultrasonic transducers (PMUTs), mounted in or on the structure. The haptic effects may be created via air-coupled ultrasonic waves.

Abstract: Disclosed are methods, devices, apparatuses, and systems for an under-display ultrasonic fingerprint sensor. A display device may include a platen, a display underlying the platen, and an ultrasonic fingerprint sensor underlying the display, where the ultrasonic fingerprint sensor is configured to transmit and receive ultrasonic waves via an acoustic path through the platen and the display. A light-blocking layer and/or an electrical shielding layer may be provided between the ultrasonic fingerprint sensor and the display, where the light-blocking layer and/or the electrical shielding layer are in the acoustic path. A mechanical stress isolation layer may be provided between the ultrasonic fingerprint sensor and the display, where the mechanical stress isolation layer is in the acoustic path.

Abstract: Some disclosed implementations include an ultrasonic sensor stack and an acoustic resonator. The acoustic resonator may be configured to enhance ultrasonic waves transmitted by the ultrasonic sensor stack in an ultrasonic frequency range that is suitable for ultrasonic fingerprint sensors. In some examples, the acoustic resonator may include one or more low-impedance layers residing between a first higher-impedance layer and a second higher-impedance layer. Each of the one or more low-impedance layers may have a lower acoustic impedance than an acoustic impedance of the first higher-impedance layer or an acoustic impedance of the second higher-impedance layer. At least one low-impedance layer may have a thickness corresponding to a multiple of a half wavelength at a peak frequency of the acoustic resonator. The peak frequency may be within a frequency range from 1 MHz. to 20 MHz.
