    Abstract: A capacitive sensing system for determining mass displacement and direction is disclosed. In an embodiment, a capacitive sensing system for sensing mass displacement and direction comprises: a mass; a periodic drive electrode pattern formed on or attached to the mass; a sensing electrode array positioned relative to the periodic electrode pattern, the sensing electrode array operable to sense a capacitance in an overlapping area between the periodic drive electrode pattern and the sensing electrode array; and a capacitive sensing circuit coupled to at least the sensing electrode array, the capacitive sensing circuit operable to generate a periodic signal based on the sensed capacitance, to determine a phase shift in the periodic signal in response to the periodic drive electrode pattern moving relative to the sensing electrode array, and to determine, based on the phase shift, a displacement and direction of the mass on a movement axis.

    Abstract: A wearable electronic device such as an earbud, wristwatch, or other device may be provided with a skin sensor. The skin sensor may use optical measurements to detect the presence of skin adjacent to the electronic device. The sensor may have first and second light-emitting devices such as infrared devices that emit light at respective first and second infrared light wavelengths. Reflected light is monitored by a photodetector. Control circuitry can initiate or pause audio playback or take other actions in response to determining from the reflected light measurements that skin is present. The sensor may have a thin-film interference filter or other optical structure that overlaps the first and second light-emitting devices to narrow the angular spread of light emitted from the skin sensor. This reduces tilt sensitivity and helps enhance skin sensor accuracy.

    Abstract: An apparatus is disclosed. In some examples, the apparatus comprises a cover substrate having a front surface, a first edge and a first cavity adjacent to the first edge. In some examples, the apparatus comprises a plurality of touch sensor electrodes disposed opposite the front surface of the cover substrate. In some examples, the apparatus comprises at least one touch sensor edge electrode disposed within the first cavity on a surface that is angled relative to the front surface of the cover substrate. In some examples, at least one touch sensor edge electrode is disposed on an outward facing curved surface of the first cavity. In some examples, the plurality of touch sensor electrodes are formed from a first conductive material and the at least one touch sensor edge electrode is formed from a second conductive material. In some examples, the first conductive material is transparent, and the second conductive material is non-transparent. In some examples, the second conductive material is formed on a black mask layer disposed around a perimeter of a bottom surface of the cover substrate.

    Abstract: In various implementations, a sensor operates in a force sensing mode by determining an applied force based on a first change in capacitance between first and second electrodes related to compression of a compressible material positioned between while the third electrode functions as a shield and in a proximity sensing mode by sensing proximity of an object based on a second change in capacitance of the third electrode while the first and/or second electrodes function as a shield. In some implementations, a device has a cover glass including a surface having a display area, an edge surface, and a cavity; a touch sensing electrode oriented toward the surface; an electrode positioned in the cavity oriented toward the edge surface; and a processing unit operable to detect touch or proximity of an object to the edge surface based on a change in capacitance between the electrode and the object.
