Abstract: An ultrasonic touch sensor includes a touch structure including a touch surface configured to receive a touch, a signal generator configured to generate an excitation, a capacitive ultrasonic transmitter configured to transmit an ultrasonic transmit wave toward the touch structure based on the excitation signal while the touch surface is submerged under the water, a capacitive ultrasonic receiver configured to receive an ultrasonic reflected wave produced by a reflection of the ultrasonic transmit wave at the touch structure while the touch surface is submerged under the water and generate a measurement signal representative of the ultrasonic reflected wave, and a measurement circuit configured to perform a comparison based on the measurement signal and a threshold, and determine whether a no-touch event or a touch event has occurred at the touch surface while the touch surface is submerged under the water based on whether the measurement signal satisfies the threshold.

Abstract: An ultrasonic fingerprint sensor may include sensor pixels with interleaved ultrasonically-sensitive regions. Each of a plurality of sensor pixels in the ultrasonic fingerprint sensor may include nine distinct ultrasonically-sensitive regions electrically coupled to a common readout circuit, where there is an ultrasonically-sensitive region of another sensor pixel disposed between each of the nine distinct ultrasonically-sensitive regions. The ultrasonic fingerprint sensor may further include circuitry for binning together groups of sensor pixels during certain lower-resolution operations such as touch sensor operations. The ultrasonic fingerprint sensor may be used in capturing fingerprint images that are then used in an authentication process.

Abstract: A device-agnostic system for detecting one or more sound profiles, each of the one or more sound profiles including at least one spectrogram produced from sound associated with a touch input and mapped to a control operation for a device, the system including a transducer and a processor. The transducer can detect a sound produced from touching a surface and produce an electrical signal from the detected sound. The processor is configured to receive the electrical signal from the transducer, convert the received electrical signal to a spectrogram, determine, using image recognition, that the spectrogram meets or surpasses a similarity threshold to one of the one or more sound profiles, and change at least one characteristic of the device based on the control operation mapped to the determined sound profile.

Abstract: Touch control surfaces for electronic user devices are disclosed herein. An example electronic device includes a microphone array and processor circuitry to detect a first acoustic event based on signals output by the microphone array, the first acoustic event indicative of a first touch on a surface of the device at a first time; detect a second acoustic event based on the signals, the second acoustic event indicative of a second touch on the surface at a second time; determine a first location of the first touch and a second location of the second touch; identify the first time and the second time as occurring within a threshold period of time; identify a gesture based on the first location, the second location, and the occurrence of the first touch and the second touch within the threshold; and cause an output at the device in response to the gesture.

Abstract: A system providing various improved calibration techniques for haptic feedback is described. An acoustic field is defined by one or more control points in a space within which the acoustic field may exist. Each control point is assigned an amplitude value equating to a desired amplitude of the acoustic field at the control point. Because complete control of space is not possible, controlling the acoustic field at given points yields erroneous local maxima in the acoustic field levels at other related positions. In relation to mid-air haptic feedback, these can interfere in interactions with the space by creating secondary effects and ghost phenomena that can be felt outside the interaction area. The level and nature of the secondary maxima in the acoustic field is determined by how the space is controlled. By arranging the transducer elements in different ways, unwanted effects on the acoustic field can be limited and controlled.

Abstract: A method for performing input sensing using an input device includes: receiving, at a sensing region of the input device, an input; obtaining, via receivers of the input device, measurements corresponding to the input, wherein obtaining the measurements comprises: separately driving multiple subsets of transmitters of the input device, and obtaining measurements corresponding to each separately-driven subset of transmitters via the receivers, wherein each separately-driven subset of transmitters comprises a plurality of non-contiguous transmitters; and generating, by a processing system of the input device, an image of the input based on the obtained measurements.

Abstract: Controlling an audio volume is disclosed. An indicator identifying a force intensity of a touch input provided on a touch input surface is received. It is determined that the touch input is associated with an audio volume control. The audio volume is controlled based at least in part on the indicator identifying the force intensity of the touch input.

Abstract: Methods and apparatus of embodiments of the present invention include a classification system configured to treat edge contact of a touch screen as a separate class of touch events such that any touches occurring near the edge of the touch screen are to be processed by a classifier that is configured to process edge contacts as compared to a classifier that is configured to process other contacts that may occur in the approximate middle of the touch screen which may be wholly digitized. An apparatus may employ two separate and distinct classifiers, including a full touch classifier and an edge touch classifier. The touch screen may be configured to have two different sensing regions to determine which of the two classifiers is appropriate for a touch event.
