    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.

    Abstract: Embodiments of the present disclosure provide an optical encoder for an electronic device. The optical encoder comprises an elongated shaft and a plurality of markings axially 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 an array of photodiodes. The emitter and the array of photodiodes may be radially aligned with respect to the elongated shaft or axially aligned with respect to the shaft.

    Abstract: A portable electronic device including a proximity sensing device having an emitter and a detector. The electronic device further including a housing for containing the proximity sensing device which includes an optical interface forming a face of the housing through which radiation between the emitter and the detector pass. The optical interface may include an oleophobic coating which is selectively modified such that optical interference from an optical interface near-field object on the proximity sensing device is reduced without reducing a sensitivity of the proximity sensing device to a target near-field object.

    Abstract: An electronic device may be provided with a touch screen display that is controlled based on information from a proximity sensor. The proximity sensor may have a light source that emits infrared light and a light detector that detects reflected infrared light. When the electronic device is in the vicinity of a user's head, the proximity sensor may produce data indicative of the presence of the user's head. Variations in proximity sensor output due to user hair color and smudges on the proximity sensor can be accommodated by using an electrical sensing mechanism in addition to the light sensing mechanism. The proximity sensor may include a pair of capacitive electrodes for generating an electric field in the vicinity of the device. The presence of a user's head can sufficiently disturb the electric field so as to produce data indicative of the presence of the user's head.
