Abstract: An electronic device including optical sensing with a concentric architecture and methods for operation thereof is disclosed. The concentric architecture can include light detector(s) arranged in a concentric manner around light emitter(s). In some examples, at least one light emitter can be located in the center of the device, and each light detector can be located the same separation distance from the light emitter. Each light detector can be arranged such that the separation distance from the centrally located light emitter can be greater than the separation distance from another light emitter. Examples of the disclosure further include a selective transparent layer overlaying the light detector(s). The selective transparent layer can include section(s) transparent to a first wavelength range and non-transparent to a second wavelength ranges. In some examples, the selective transparent layer can further include section(s) transparent to the second wavelength range.

Abstract: An electronic device such as a portable electronic device may include a single-shot alignment-free spectrometer with no moving parts. The spectrometer may include a diffractive member, such as a grating, an aperture, and an image sensor that generates data in response to incident light. The diffractive member may diffract the incident light based on its wavelength and angle of incidence, and the aperture may further encode the light. The data generated by the image sensor may be used by control circuitry in combination with correlations between spectrometer measurements and known light profiles to determine the wavelength and angle of incidence of the light. These correlations may be determined using a deep neural network. Control circuitry may adjust one or more settings of the electronic device based on the wavelength and angle of incidence, or may use the wavelength and angle of incidence to determine information regarding an external object.

Abstract: An electronic device can include a housing that includes an optically transparent component. First and second light emitters can be positioned in the internal volume defined by the housing. A light detector can be positioned in the internal volume and can be optically isolated from the first and second light emitters within the internal volume. An opaque material can be disposed on the optically transparent component and can be positioned to inhibit light emitted from the second light emitter from reaching the light detector and to allow light emitted from the first light emitter to reach the light detector.

Abstract: An electronic device may have a display with an array of pixels that display images for a user. The electronic device may have an ambient light sensor for gathering ambient light information. A subset of the pixels in the array of pixels may overlap the ambient light sensor so that ambient light passing through the subset of pixels may be measured. Each pixel may have an emission enable transistor coupled in series with a light-emitting diode. Control circuitry in the electronic device may disable the subset of pixels to reduce stray light during ambient light measurements while enabling remaining pixels in the array of pixels to display an image. Ambient light sensor circuitry may gather ambient light sensor measurements over one or more periods by using transfer transistors to transfer change from the photodetectors to charge storage capacitors formed from floating diffusions in a common substrate.

Abstract: An assembly for a consumer product, such as a wristwatch or other wearable electronic device, can securely retain a cover member against a housing of the product. A retaining member from within the housing can engage and secure the cover member to provide a fluid barrier. The cover member can include a window or other components of a sensor device. The parts can be easily disassembled without causing permanent damage.
