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: An electronic device is disclosed. In some examples, the electronic device comprises a housing and an input mechanism cooperatively engaged with the housing and configured to rotate in a first direction about a rotation axis. In some examples, the electronic device comprises an input sensor configured to sense an input at the input mechanism based on rotation of the input mechanism. In some examples, the electronic device comprises an actuator coupled to the housing and configured to displace the input mechanism. In some examples, the electronic device comprises a force sensor coupled to the input mechanism and configured to sense an input at the input mechanism based on a force applied to the input mechanism along the second axis.

Abstract: An apparatus is disclosed. In some examples, the apparatus comprises a mechanical input mechanism comprising a rotatable shaft. In some examples, the apparatus comprises an optical sensor configured to detect a rotation of the shaft and detect a movement of the shaft toward or away from the optical sensor. In some examples, the apparatus comprises an optical sensor configured to detect light incident on the optical sensor, the light having a position and an orientation, the orientation of the light based on at least a position of the rotatable shaft, detect a rotation of the shaft, and detect a movement of the shaft based on at least a change in the orientation of the light. In some examples, the apparatus comprises a housing. In some examples, a mechanical input mechanism comprising a rotatable shaft is coupled to the housing and configured to contact a force sensor coupled to the housing in response to a user input. In some examples, the force sensor is configured to detect a position of the shaft and detect an amount of force between the shaft and the force sensor that is based on the user input.
