Abstract: An apparatus may include a platen, a light source system and an ultrasonic receiver system. The light source system may be configured to provide light to a target object on an outer surface of the platen. The light source system may be configured to direct the light along a first axis oriented at a first angle relative to the outer surface of the platen. The ultrasonic receiver system may be configured to receive ultrasonic waves generated by the target object responsive to the light from the light source system. The ultrasonic receiver system may include one or more receiver elements residing in a receiver plane. A normal to the receiver plane being may be oriented along a second axis at a second angle relative to the outer surface of the platen. The first angle may be different from the second angle.

Abstract: Techniques for operating an ultrasonic sensor array, the ultrasonic sensor array disposed under a platen, include making a determination whether or not to recalibrate the ultrasonic sensor array based on whether a first screen protector disposed above the platen has been removed or replaced by a second screen protector; and recalibrating the ultrasonic sensor array, when the determination is to recalibrate the ultrasonic sensor array. In some cases, the techniques include prompting a user to indicate whether or not the screen protector has been changed or removed, and recalibrating the ultrasonic sensor array only after confirmation from the user.

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.

CPC classification number: G06V40/1306 , G06F21/32 , H03H9/17
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.

Abstract: An apparatus may include an ultrasonic sensor stack, a foldable display stack and a transmission enhancement layer. The foldable display stack may include a display stiffener and display stack layers. The display stack layers may form one or more display stack resonators configured to enhance ultrasonic waves transmitted by the ultrasonic sensor stack in a first ultrasonic frequency range. In some implementations, a transmission enhancement resonator may include the display stiffener and the transmission enhancement layer. In some examples, the transmission enhancement resonator may include at least a portion of the ultrasonic sensor stack. The transmission enhancement resonator may be configured to enhance the ultrasonic waves transmitted by the ultrasonic sensor stack in the first ultrasonic frequency range.
