摘要： An electronic device may have a housing. Input-output devices may be mounted in the housing. The input-output devices may include a display with an array of pixels configured to display images for a user. The electronic device may have an optical component formed under a transparent region in the housing. The transparent region may be associated with an opening in an opaque masking layer in an inactive area of the display or other portion of the electronic device. A diffuser may be formed between the optical component and the transparent region. The diffuser may have a polymer layer with embedded thin-film interference filter flakes configured to scatter light and to exhibit desired reflection and transmission spectral.

摘要： A method includes imaging, with an optical read head attached to a second mechanical component, a portion of an encoder track disposed on a first mechanical component. The encoder track has a first encoder scale extending along the encoder track and a second encoder scale extending along the encoder track, and the imaged portion of the encoder track includes a first portion of the first encoder scale and a second portion of the second encoder scale. The method further includes transforming an imaged portion of the encoder track to a spatial frequency domain; identifying a pair of frequency bins in the spatial frequency domain; determining a phase difference between a first frequency bin and a second frequency bin in the pair of frequency bins; and mapping the phase difference to a positional relationship between the first mechanical component and the second mechanical component.

摘要： An electronic device includes a housing and a display. The housing defines an interior cavity and includes an optically-transmissive housing component. The display is disposed in the interior cavity and is viewable through the optically-transmissive housing component. An optoelectronic component is disposed in the interior cavity. An optical fiber extends between a first end positioned adjacent the optoelectronic component and a second end positioned adjacent the optically-transmissive housing component. The optical fiber defines a non-linear optical path between the first end and the second end. At least a portion of the optical fiber is laterally offset from a lateral edge of the display.

摘要： A color ambient light sensor may gather ambient light measurements during operation of an electronic device. The color ambient light sensor may have a color ambient light detector and an adjustable neutral density filter. The electronic device may have components such as a camera and display that are adjusted using ambient light information from the color ambient light sensor. The display may have a display cover layer. Pixels in an active area of the display may display images through the display cover layer. An inactive area of the display may have an opaque masking layer on an interior surface of the display cover layer. An opening in the opaque masking layer may form an ambient light sensor window for the color ambient light sensor. The adjustable neutral density filter may be interposed between the color ambient light detector and the ambient light sensor window.

摘要： An electronic device may be provided with a display. The display may have an array of pixels that form an active area and may have an inactive area that runs along an edge of the active area. An opaque layer may be formed on an inner surface of a display cover layer in the inactive area of the display or may be formed on another transparent layer in the electronic device. An ambient light sensor window may be formed from the opening and may be aligned with color ambient light sensor. The ambient light sensor may have an integrated circuit with photodetectors. Ambient light passing through the ambient light sensor window may be diffused by a light diffuser having one or more light-diffusing layers. Diffused ambient light may be collimated using a light collimator having one or more light-collimating layers such as layers with inwardly facing protrusions.

摘要： One or more strain sensors can be included in an electronic device. Each strain sensor includes a strain sensitive element and one or more strain signal lines connected directly to the strain sensitive element. The strain sensor(s) are used to detect a force that is applied to the electronic device, to a component in the electronic device, and/or to an input region or surface of the electronic device. A strain sensitive element is formed or processed to have a first gauge factor and the strain signal line(s) is formed or processed to have a different second gauge factor. Additionally or alternatively, a strain sensitive element is formed or processed to have a first conductance and the strain signal line(s) is formed or processed to have a different second conductance.
