Abstract: Acoustic touch detection (touch sensing) system architectures and methods can be used to detect an object touching a surface. Position of an object touching a surface can be determined using time-of-flight (TOF) bounding box techniques, or acoustic image reconstruction techniques, for example. Acoustic touch sensing can utilize transducers, such as piezoelectric transducers, to transmit ultrasonic waves along a surface and/or through the thickness of an electronic device. Location of the object can be determined, for example, based on the amount of time elapsing between the transmission of the wave and the detection of the reflected wave. An object in contact with the surface can interact with the transmitted wave causing attenuation, redirection and/or reflection of at least a portion of the transmitted wave. Portions of the transmitted wave energy after interaction with the object can be measured to determine the touch location of the object on the surface of the device.

Abstract: A capacitive sensing apparatus is disclosed. In some examples, the capacitive sensing apparatus includes a sensor control system configured to: during a first scan of the sensor array: transmit a first alternating current (AC) signal concurrently with a second alternating current (AC) signal to the sensor array, transmit the first AC signal to the first electrode of the sensor array, measure a self capacitance at the first input location, and transmit the second AC signal to the second electrode of the sensor array without measuring a self capacitance at the second input location, and during a second scan of the sensor array: transmit the first AC signal concurrently with the second AC signal to the sensor array, transmit the first AC signal to the first electrode of the sensor array without measuring the self capacitance at the first input location, and measure the self capacitance at the second input location.

Abstract: Detecting a signal from a touch and hover sensing device, in which the signal can be indicative of concurrent touch events and/or hover events, is disclosed. A touch event can indicate an object touching the device. A hover event can indicate an object hovering over the device. The touch and hover sensing device can ensure that a desired hover event is not masked by an incidental touch event, e.g., a hand holding the device, by compensating for the touch event in the detected signal that represents both events. Conversely, when both a hover event and a touch event are desired, the touch and hover sensing device can ensure that both events are detected by adjusting the device sensors and/or the detected signal. The touch and hover sensing device can also detect concurrent hover events by identifying multiple peaks in the detected signal, each peak corresponding to a position of a hovering object.
