SYSTEMS AND METHODS FOR INCREASING LOCALIZED PRESSURE TO IMPROVE PPG MOTION PERFORMANCE
First Claim
1. A device comprising:
- one or more optical components;
one or more cover structures, each cover structure optically coupled to at least one of the one or more optical components and located on a back surface of the device;
a rigid back plate extending from the back surface of the device; and
one or more protrusions extending from the rigid back plate, wherein an area of the one or more protrusions is less than an area of the rigid back plate.

Abstract
The relates to a back surface of the device including one or more protrusions configured to create the localized pressure. In some examples, the protrusion(s) can be located between the optical components and one or more edges of the back plate. In some examples, the protrusion(s) can include a surface that can be raised relative to the back plate of the device. In some examples, one or more protrusions can include one or more recessed regions. In some examples, the cover structure disposed over each of the openings may itself be a protrusion that can apply local regions of higher pressure. The protrusion(s) can be capable of applying localized pressure to multiple spatially separated regions of the skin. Additionally or alternatively, the protrusion(s) can be capable of applying different amounts of localized pressure. Examples of the disclosure can include the Fresnel lens(es) and/or optical isolation optically coupled to the protrusion.

17. A method for determining one or more physiological signals of an individual, the method comprising:
-
emitting light from one or more light emitters; allowing the emitted light to pass through one or more first cover structures; receiving at least a portion of the emitted light using one or more light sensors; creating a first localized pressure at one or more first regions of a skin of the individual; allowing the at least the portion of the emitted light to pass through one or more second cover structures; generating one or more signals indicative of the received light; and determining the one or more physiological signals of the individual from the one or more signals. - View Dependent Claims (18)

19. A method for determining one or more physiological signals of an individual, the method comprising:
-
emitting light from one or more light emitters located on a first side of a cover structure; optically isolating the emitted light from a second side of the cover structure; allowing the emitted light to pass through the first side of the cover structure; allowing at least a portion of the emitted light to pass through the second side of the cover structure; optically isolating the at least the portion of the emitted light from the second side of the cover structure; receiving the at least the portion of the emitted light using one or more light sensors located on the second side of the cover structure; generating one or more signals indicative of the received light; and determining the one or more physiological signals of the individual from the one or more signals. - View Dependent Claims (20)
