    Abstract: An electronic device is disclosed. In some examples, the electronic device comprises a rotatable mechanical input mechanism. In some examples, the electronic device comprises sense electrode positioned proximate to the mechanical input mechanism. In some examples, the electronic device comprises a capacitive sense circuit comprising drive circuitry operatively coupled to the mechanical input mechanism and configured for driving a drive signal onto the mechanical input mechanism. In some examples, the electronic device comprises a capacitive sense circuit comprising sense circuitry operatively coupled to the sense electrode and configured to measure an amount of coupling between the rotatable mechanical input mechanism and the sense electrode. In some examples, the electronic device comprises a housing, wherein the sense electrode is included in a gasket for connecting a display to the housing.

    Abstract: In some examples, an optical encoder may consist of a light source that shines light onto a wheel which then reflects the light onto a sensor. Using information encoded in the reflected light, the rotation of the wheel may be determined. In some examples, rotation of the wheel may be determined by detecting an encoding pattern in light reflected from an exterior surface of the wheel. In some examples, the encoding pattern can be a pattern of light and dark stripes. In some examples, a pattern of light stripes can be generated from light reflecting off of reflective portions of the wheel. Some examples of the disclosure relate to using a surface topology for a wheel that can be used to generate an encoding pattern of light and dark stripes in light reflected from the surface of the wheel, even when the surface of the wheel is uniformly reflective.

    Abstract: A wearable device is disclosed. The wearable device can comprise a housing; a crown; a proximity sensor; and a processor. The crown can be configured to receive input from a user. The proximity sensor can be configured to generate a field of view encompassing a first area adjacent to the housing and further configured to generate an output signal corresponding to whether an object is present within the field of view. The processor can be configured to determine, based on the output signal, whether the input corresponds to an intentional input or an unintentional input.

    Abstract: Examples of the disclosure enclose an optical target on an encoder and sensors inside a single integrated module, wherein the encoder and the sensors are coupled to the same rigid body to maintain optical alignment between the sensors and the optical target on the encoder. Further, the module itself may be hermetically sealed to protect the optical path (e.g., from a light source to the optical target to the sensors) from contamination due to outside dirt, debris, or light sources internal/external to the device that might further interfere with alignment and/or proper sensing. Because the integrated module results in smaller variations in the alignment between the optical target and the sensors, the dynamic range of the sensors may be reduced, resulting in less power consumption and, potentially, longer battery life for the device. The use of an integrated module can also enable relaxed manufacturing requirements for the optical sensor and/or the optical target.
