    Abstract: Embodiments of the present disclosure provide an optical encoder for an electronic device. The optical encoder comprises an elongated shaft having an encoding pattern made up of axial markings and radial markings. The encoding pattern may be disposed around a circumference of the elongated shaft. The optical encoder also includes an optical sensor. In embodiments, the optical sensor includes an emitter and a photodiode array. The emitter causes light to shine on the encoding pattern. The encoding pattern reflects the light back to the photodiode array and the photodiode array determines movement of the shaft based on the reflected light.

    Abstract: Various embodiments for detecting and rejecting false, unintended rotations of rotary inputs of electronic devices are disclosed herein. In one example, an electronic device is provided with an optical detector that measures the distance between the electronic device and the wearer's forearm or hand, and when the distance is smaller than a threshold distance, the turns of the rotary input are false, unintended turns. In another example, a crown of a rotary input includes a plurality of capacitive sensors that detects the presence of a wearer's finger, which when absent, the turns of the rotary input are false turns. In another example, deflections or positions of a shaft of the rotary input are measured and if the deflections/positions indicate an upward force on the rotary input (which are likely caused by the wearer's forearm or hand), the turns of the rotary input are false turns. Other embodiments are described herein.

    Abstract: Embodiments are directed to a circuit assembly for an electronic device having an electromagnetic shield that defines a sensing element or contact pad along an outer surface of the assembly. The circuit assembly includes a group of electrical components attached to a surface of a printed circuit board. A molded structure may encapsulate the group of electrical components and at least a portion of the surface of the printed circuit board. A metal layer may be formed over an outer surface of the molded structure. The metal layer may define both a shield portion configured to provide shielding for one or more of the group of electrical components and an electrode configured to detect an input applied to the electronic device.
