Abstract: A computing system comprises a processor and internal peripheral devices, and a system bus connecting the internal peripheral devices to the processor. One of the internal peripheral devices is an ultrasonic digitizer that digitizes ultrasonic signals from at least two associated microphones into a digitized audio signal carrying a corresponding location and outputs the digitized audio as a signal on the system bus.

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: A computing system comprises a processor and internal peripheral devices, and a system bus connecting the internal peripheral devices to the processor. One of the internal peripheral devices comprises an ultrasonic digitizer configured for digitization of ultrasonic frequencies and the digitizer digitizes ultrasonic signals from at least two associated microphones into a corresponding digitized audio output and outputs the digitized audio output as a signal on the system bus.
