Abstract: An optical measurement module is disclosed that includes three or more recessed regions separated from each other by two or more barrier walls, the recessed regions including at least two distal recessed regions. The optical measurement module may also include first and second photo-emitter elements that emit light in different spectrums and first and second photodetector elements. One or more of the second photo-emitter elements may be located in one of the distal recessed regions, and the second photodetector element may be located in one of the other distal recessed regions. The first photodetector element may be located in a recessed region other than the recessed region where the second photodetector element is located, and the one or more photo-emitter elements may be located in one of the recessed regions other than the one where the first photodetector element is located.

Abstract: In one embodiment, a data processing method comprises obtaining one or more first photoplethysmography (PPG) signals based on one or more first light sources that are configured to emit light having a first light wavelength corresponding to a green light wavelength; obtaining one or more second PPG signals based on one or more second light sources that are configured to emit light having a second light wavelength corresponding to a red light wavelength, one or more of the first light sources and one or more of the second light sources being co-located; generating an estimated heart rate value based on one or more of the first PPG signals and the second PPG signals; and causing the estimated heart rate value to be displayed via a user interface on a client device.

Abstract: Light-blocking structures for optical physiological parameter measurement devices or sensors are disclosed. Such optical physiological parameter measurement devices or sensors may include two photodetectors and a photo-emitter, as well as barrier walls that are interposed between the photo-emitter and the photodetectors. The barrier walls may have recesses that intermesh with surface profiles of protrusions that are attached to or part of a window of the optical physiological parameter measurement devices or sensors.

Abstract: Light-blocking structures for optical physiological parameter measurement devices or sensors are disclosed. Such structures may include barrier walls and protrusions that further include intermeshing surface profiles designed to promote light-blocking capabilities at small scales to offset potential gaps that may occur due to assembly tolerance stack-ups.
