Abstract: In some embodiments, an integrated virtual button module includes a first transducer, a microcontroller, and a first driver circuit. The first transducer includes a transient strain-sensing element and is configured to generate first signals. The microcontroller is configured to obtain first data from the first signals and determine user inputs in accordance with at least the first data. The first driver circuit is configured to receive user feedback data and to generate a first user feedback signal in accordance with the user feedback data. The first driver circuit is electronically couplable to a first actuator. The user feedback data are determined in accordance with at least the user inputs. The first actuator emits a haptic signal and/or a first audio signal when driven by the first user feedback signal. Embodiments of an integrated virtual button system and a method of determining user input and providing user feedback are also disclosed.

Abstract: Touch events can be detected using an ultrasound input device coupled to a surface, such as a surface of a piece of furniture or electronic device. The ultrasound input device can generate ultrasonic waves in the surface, the reflections of which can be measured by the ultrasound input device. When a touch is made to the surface (e.g., opposite the ultrasound input device), the physical contact can absorb some of the energy of the outgoing ultrasonic waves (e.g., the originally transmitted wave and any subsequent outgoing reflections). Energy measurements associated with the measured reflections can thus be used to identify touch events. Various techniques can be used to make the energy measurements and reduce identification of false touch events.

Abstract: A method includes receiving energy data associated with an ultrasound input device coupled to a material layer. The energy data comprises a current energy value and past energy values associated with reflected ultrasound signals received at the ultrasound input device in response to the ultrasound input device transmitting emitted signals through the material layer towards an external surface of the material layer. The method can then include comparing the energy data with threshold data to generate a current trigger value for trigger data. The trigger data is indicative of an occurrence of a touch event when the current energy value exceeds a current threshold value of the threshold data. Then the method can include updating the threshold data based on the energy data, the trigger data, and the threshold data. Updating the threshold data comprises generating a subsequent threshold value.

Abstract: An ultrasound input device can be coupled to a material layer having an external surface located opposite the material layer from the ultrasound input device. The ultrasound input device can transmit an emitted signal through the material layer towards the external surface and receive a set of reflected ultrasound signals associated with the emitted signal. The set of reflected ultrasound signals comprises at least one reflected ultrasound signal, and the set of reflected ultrasound signals can be associated with a touch event between an object and the external surface. A system can comprise one or more data processors configured for performing operations including determining an energy signal associated with the set of reflected ultrasound signals, extracting feature information associated with the energy signal, determining an inference associated with the object based on the extracted feature information, and generating an output signal associated with the determined inference.

Abstract: A system includes a piezoelectric capacitor assembly and signal processing circuitry coupled to the piezoelectric capacitor assembly. The piezoelectric capacitor assembly includes a piezoelectric member and piezoelectric capacitors located at respective lateral positions along the piezoelectric member. Each piezoelectric capacitor includes: (1) a respective portion of the piezoelectric member, (2) a first electrode, and (3) a second electrode. The first and second electrodes are positioned on opposite side of the piezoelectric member. The piezoelectric capacitors include piezoelectric force-measuring elements (PFEs). The PFEs are configured to output voltage signals between the respective first electrode and the respective second electrode in accordance with a time-varying strain at the respective portion of the piezoelectric member between the respective first electrode and the respective second electrode resulting from a low-frequency mechanical deformation. The signal processing circuitry is configured to read at least some of the PFE voltage signals.
