Abstract: Locating a lost stylus, or other peripheral input device can be made possible by acoustic resonators integrated within housing structures of the stylus. Acoustic resonators can be formed at an end of the stylus opposite its tip, and can include portions of the stylus outer housing that are thinned down to an engineered thickness that has a particular resonant behavior or frequency. In some examples, acoustic resonators can be formed at a cap portion of the stylus, and can include a resonant diaphragm attached to at least a portion of a cap boundary. Cap coverings for the cap portion can optionally have openings to allow ventilation for changes in air pressure generated beneath the covering. In some examples, an electronic device can communicate a location request to the stylus and can cause the stylus to generate an acoustic signal for a specified target detector using the acoustic resonators.

Abstract: Examples of the disclosure are directed to micro-machined ultrasonic transducers (MUTs) which can be embedded into a flexible band of a watch to detect touch, gestures, physiological signals, and transfer data. In some examples, the MUTs can include a piezoelectric material disposed between two electrodes and coupled to a base material having a plurality of cavities, to support motion of the transducer structure. In some examples, the MUTs can be coupled to multiplexing circuitry to stimulate, configure and control the MUTs. In some examples, the size, shape, and arrangement of transducers can be changed to improve characteristics associated with ultrasonic transmission. In some examples, the MUT array can be driven (e.g., by the CMOS circuitry) to beamform the transmitted and/or the received ultrasonic waves. In some examples, the one or more MUT arrays can be configured to generate haptic feedback via the flexible band.

Abstract: A haptic actuator may include a housing that includes a ferromagnetic material having a first heat conductance, and a coil carried by the housing in a medial portion thereof and generating waste heat when electrically powered. The haptic actuator may also include a field member movable within the housing responsive to the coil. The field member may include at least one permanent magnet establishing a magnetic path with the housing. A heat spreading layer may be thermally coupled to the housing adjacent the coil. The heat spreading layer may have a second heat conductance greater than the first heat conductance to spread the waste heat from the coil to adjacent portions of the housing.
