Abstract: In some aspects, an electronic device may display a keyboard user interface on a touchscreen display panel. The electronic device may detect a key press interaction with the keyboard user interface. The electronic device may trigger one or more haptic actuators to generate a vibration waveform associated with a haptic pattern that is based at least in part on a context associated with the key press interaction. Numerous other aspects are described.

Abstract: Innovative techniques to design and generate haptics waveforms are proposed. The proposed techniques enable consistent haptics user-experience to be enable despite variations among different haptic actuators. Arbitrary waveforms may be generated without selecting from a list of pre-determined waveforms.

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 apparatus may include an ultrasonic sensor system, a low-frequency vibration source and a control system. The ultrasonic sensor system may include an ultrasonic receiver and an ultrasonic transmitter configured for transmitting ultrasonic waves in a first frequency range (e.g., 1 MHz to 30 MHz). The low-frequency vibration source may be configured for generating low-frequency vibrations in a second frequency range (e.g., the range of 5 Hz to 2000 Hz). The control system may be configured for synchronizing the generation of the first low-frequency vibrations and the transmission of the first ultrasonic waves.

Abstract: An apparatus may include a cover layer, a layer of first metamaterial proximate (or in) the cover layer, a light source system configured for providing light to the layer of first metamaterial and a receiver system. The first metamaterial may include nanoparticles configured to create ultrasonic waves when illuminated by light. The receiver system may include an ultrasonic receiver system configured to receive ultrasonic waves reflected from a target object in contact with, or proximate, a surface of the cover layer. The control system may be configured to receive ultrasonic receiver signals from the ultrasonic receiver system corresponding to the ultrasonic waves reflected from the target object and to perform an authentication process and/or an imaging process that is based, at least in part, on the ultrasonic receiver signals.

Abstract: Audio and haptic signal processing systems and methods are provided. There is provided a method for haptic drive signal generation. The method comprises receiving an input audio signal for driving an audio speaker. The method further comprises deriving, from the audio signal, data components indicative of behaviour of the audio speaker when being driven by the input audio signal, each data component being associated with a respective frequency range. The method further comprises determining a haptic drive component from each data component. A gain is selected to provide to each of the haptic drive components, the gain being selected for each respective frequency range. Each selected gain is applied to the respective haptic drive component to produce gain adjusted haptic drive components. A haptic drive signal is determined from the gain adjusted haptic drive components, the haptic drive signal being so as to produce a mechanical behaviour of the haptic actuator when the haptic drive signal is used to drive the haptic actuator
