Abstract: Acoustic touch and/or force sensing system architectures and methods for acoustic touch and/or force sensing can be used to detect a position of an object touching a surface and an amount of force applied to the surface by the object. The position and/or an applied force can be determined using time-of-flight (TOF) techniques, for example. Acoustic touch sensing can utilize transducers (e.g., piezoelectric) to simultaneously transmit ultrasonic waves along a surface and through a thickness of a deformable material. The location of the object and the applied force can be determined based on the amount of time elapsing between the transmission of the waves and receipt of the reflected waves. In some examples, an acoustic touch sensing system can be insensitive to water contact on the device surface, and thus acoustic touch sensing can be used for touch sensing in devices that may become wet or fully submerged in water.

Abstract: An electronic device such as a pair of headphones may be provided with ear cups having speakers for playing audio to a user. Capacitive sensor electrodes may be used in capturing capacitive sensor ear images that are processed by a machine learning classifier to determine whether the headphones are being worn in a reversed or unreversed orientation. The capacitive sensor electrodes may include grill electrodes that overlap at least part of a speaker grill, cushion electrodes that make capacitive sensor measurements through ring- shaped ear cup cushions that surround the speaker grills, and ring electrodes. The ring electrodes may be formed from metal traces on a flexible printed circuit. The flexible printed circuit may include a portion that wraps around each speaker grill and that is surrounded by a corresponding one of the cushions.

Abstract: A wireless power system includes an electrically-balanced inductor in a transmitter device and an electrically-balanced inductor in a receiver device. The electrically-balanced inductors can be formed by introducing crossovers between radially-adjacent portions of two separate turns of each inductor. The crossovers balance the electric field generated by the transmitter device when transferring power to the receiver device.

Abstract: Touch-based input devices, such as a stylus, can receive tactile input from a user. The tactile input functions can be performed by a touch sensor, such as a capacitive sensing device. A touch sensor can be integrated into a stylus in a low profile form. Tactile input can be received at the user's natural grip location. Furthermore, the stylus can effectively distinguish between tactile inputs from a user and disregard sustained tactile inputs that are provided while the user simply holds the stylus at the user's natural grip location.

Abstract: Systems and methods for wireless power transfer to an electronic device. In some embodiments, the disclosed devices includes one or more arrays of transmit coils within a charging surface on which an electronic device is placed for charging. A controller may apply a first alternating signal with a first phase to a first transmit coil, and a second alternating signal with a second phase to a second transmit coil. The offset of phases may produce increased magnetic flux through a receive coil of the electronic device to transfer power more efficiently.
