Abstract: Systems and methods described herein relate to fingerprint-on-display recognition. In particular, the systems and methods described herein may recognize a fingerprint when a finger of a user is placed on a display and authenticate the user based on the recognized fingerprint. Further, the embodiments described herein may utilize multiple colors and/or secondary factors to reduce erroneous authentications of the user. The approaches may improve the accuracy of fingerprint authentication by using the multiple colors and/or secondary factors.

Abstract: Hardware architectures for ultrasonic front-end receivers used in ultrasonic sensing applications are disclosed. An example ultrasonic receiver may include a plurality of ultrasonic sensor elements. A given ultrasonic sensor element may be configured to detect an ultrasonic signal/wave that has interacted with an object being analyzed, such as a finger, if determining a fingerprint is the target of the ultrasonic sensing. The ultrasonic sensor element is further configured to generate an electrical signal indicative of the ultrasonic signal that has been detected. In contrast to conventional implementations, the electrical signal is integrated in an analog domain, prior to being converted to digital domain for further processing. Various embodiments of the ultrasonic receivers disclosed herein may benefit from one or more of reduced power consumption, reduced die area requirements, and reduced cost due to the use of a more efficient architecture.

Abstract: Embodiments of the present invention provide a user interface processing system for a device that may include at least one sensor, at least one output device, and a controller. The controller may include a memory, which may store instructional information, and a processor. The processor may be configured to receive sensor data from the at least one sensor and to interpret sensor data according to the instructional information. The processor may also generate a user interface feedback command and transmit the command to the at least one output device. Furthermore, the processor may report the sensor data to a host system of the device. By processing the sensor data and generating a corresponding feedback response, for example a haptic response, without the need for host system processing, the user interface controller may decrease latency in providing the feedback response to the user.
