Abstract: An authentication process may involve presenting an image on a display device, such as an icon associated with an application, indicating an area for a user to touch. At least partial fingerprint data may be obtained during one or more finger taps or touches in the area. Based on a comparison of the partial fingerprint data and master fingerprint data of the rightful user, a control system may determine whether to invoke a function. Invoking the function may involve authorizing a commercial transaction or unlocking the display device. In some implementations, determining whether to invoke the function may be based on a level of security.

Abstract: Systems, methods and apparatus for configuring a fingerprint sensor to operate in a capacitive sensing mode and an ultrasonic sensing mode are disclosed. A fingerprint sensor may be configured to operate in a capacitive sensing mode by driving a sensing electrode using a controller. In some implementations, an object positioned on or near the sensing electrode may be detected using the fingerprint sensor in the capacitive sensing mode, and the controller can drive electrodes of the fingerprint sensor differently to configure the fingerprint sensor to operate in an ultrasonic sensing mode. In some implementations, an applications processor may be instructed to authenticate a fingerprint of the object from image data obtained when the fingerprint sensor is operating in the ultrasonic sensing mode. In some implementations, a display of a mobile device containing the fingerprint sensor may be unlocked, or the mobile device may be woken up when the fingerprint is authenticated.

Abstract: An ultrasonic sensor pixel includes a substrate, a piezoelectric micromechanical ultrasonic transducer (PMUT) and a sensor pixel circuit. The PMUT includes a piezoelectric layer stack including a piezoelectric layer disposed over a cavity, the cavity being disposed between the piezoelectric layer stack and the substrate, a reference electrode disposed between the piezoelectric layer and the cavity, and one or both of a receive electrode and a transmit electrode disposed on or proximate to a first surface of the piezoelectric layer, the first surface being opposite from the cavity. The sensor pixel circuit is electrically coupled with one or more of the reference electrode, the receive electrode and the transmit electrode and the PMUT and the sensor pixel circuit are integrated with the sensor pixel circuit on the substrate.

Abstract: Techniques described here use variations in the sensor to generate an identifier for the sensor. Each sensor may be comprised of sub-sensing units, called pixels that may demonstrate variation in their sensing capability from one pixel to another. Embodiments of the invention, describe a method for using the relative variance of each pixel (relative to the whole sensor or/and a portion of the sensor) in generating an identifier for the sensor. In one embodiment, the method may obtain information associated with a plurality of pixels from a sensor, detect variations in the information associated for each of the pixels from a subset of the plurality of pixels and generate an identifier for the sensor using the detected variations in the information associated with each of the pixels from the subset of plurality of pixels.

Abstract: An apparatus may include a one- or two-dimensional array of micromechanical ultrasonic transducer (PMUT) elements positioned below, beside, with, on, or above a backplane of a visual display. The backplane may be a thin-film transistor (TFT) backplane. The array of PMUT elements may be a piezoelectric micromechanical ultrasonic transducer (PMUT) array or a capacitive micromechanical ultrasonic transducer (CMUT) array. The PMUT array may be configurable to operate in modes corresponding to multiple frequency ranges. When operating in the low-frequency mode, the apparatus may be capable of gesture detection. A high-frequency mode may include a fingerprint sensor mode or a stylus detection mode.
