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.
Claims16
A portable electronic device comprising:
- a housing having an opening extending from an interior surface of the housing to an exterior surface of the housing;
- a photosensor window positioned within the opening, the photosensor window including:
- a first transparent region that allows light from a photoemitter positioned within the housing to pass through the opening, and wherein the first transparent region forms a first portion of a perimeter of the photosensor window;
- a second transparent region that allows light to pass through the opening and be received by a photodetector that is positioned within the housing, and wherein the second transparent region forms a second portion of the perimeter of the photosensor window;
- and
- an opaque region positioned between and optically isolating the first transparent region from the second transparent region;
- wherein the first transparent region, the second transparent region and the opaque region are arranged to form a convex surface that forms a portion of an exterior surface of the electronic device.
A wearable electronic device comprising:
- a housing including an interface region configured to be in contact with a user's skin;
- an opening formed through the housing in the interface region;
- a physiological sensor positioned within the housing and including a photoemitter and a photodetector;
- a physiological sensor window affixed within the opening and including:
- a first transparent region positioned adjacent the photoemitter allowing light from the photoemitter to be transmitted through the opening, wherein the first transparent region forms a first portion of a perimeter of the physiological sensor window;
- a second transparent region positioned adjacent the photodetector and allowing light to pass through the opening and be received by the photodetector, wherein the second transparent region forms a second portion of the perimeter of the physiological sensor window;
- and
- an opaque region disposed between the first and the second transparent regions;
- wherein the first transparent region, the second transparent region and the opaque region are arranged to form a convex surface that forms a portion of an exterior surface of the wearable electronic device.
