Abstract: An electronic device includes a device body having a back surface, a band configured to fasten the device body to a user with the back surface facing a body part of the user, an optical sensor system, and a device removal detector. The optical sensor system has a first optical measurement path and a second optical measurement path. The first optical measurement path has a first optical path length that differs from a second optical path length of the second optical measurement path. The device removal detector is configured to generate a device removal indication responsive to either of, a first set of object proximity measurements received from the optical sensor system for the first optical measurement path, or a second set of object proximity measurements received from the optical sensor system for the second optical measurement path.

Abstract: An integrated window for a photosensor for use in an electronic device has first and second transparent regions separated by an opaque region. The first transparent region allows a transmitter to emit light out of the housing of the electronic device and the second transparent region allows a receiver to receive light through the housing. The opaque region is disposed between the first and second transparent regions to isolate them from one another such that the transmitted light is isolated from the received light.

Abstract: A wearable device is described. The wearable device includes a housing having a back cover, and an optical mask on first portions of the back cover. The back cover includes a set of windows, with a first subset of windows in the set of windows being defined by an absence of the optical mask on second portions of the back cover, and a second subset of windows in the set of windows being inset in a set of openings in the back cover. An optical barrier surrounds each window in the second subset of windows. A set of light emitters is configured to emit light through at least some of the windows in the set of windows. A set of light detectors is configured to receive light through at least some of the windows in the set of windows.

Abstract: An electronic device that can be worn by a user can include a processing device and one or more optical heart rate monitors operatively connected to the processing device. The processing device can be adapted to receive a OHRM signal from at least one optical heart rate monitor. The OHRM signal includes one or more motion artifacts that are produced by a physical activity of the user. The processing device can be adapted to analyze the OHRM signal to determine the physical activity of the user.

Abstract: A Fresnel lens can be adhered to a window in an optical apparatus by liquid optically clear adhesive (LOCA). However, during adhesion the LOCA may spill over into grooves of the Fresnel lens, and the grooves can carry the LOCA into an active area of the lens potentially causing visual artifacts and altering the functional and cosmetic optical qualities of the lens. In examples of the disclosure, one or more grooves along the circumference of a surface of the lens surrounding inner grooves of the Fresnel lens can form a barrier ring that prevents the LOCA from reaching the inner grooves.

Abstract: Disclosed herein is an electronic device including an optical sensing unit for distinguishing between a user's body and an object. The optical sensing unit can include a plurality of light detectors, a plurality of first light emitters, and a plurality of second light emitters. The plurality of first light emitters can measure physiological information of the user, and the plurality of second light emitters can measure a state of the device. The device can include one or more optical components, which can allow the plurality of second light emitters to emit first light towards the strap attached to the device and second light towards the edges of the device.

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.
