Abstract: A monitoring device configured to be attached to a subject includes a photoplethysmography (PPG) sensor configured to measure physiological information from the subject, and at least one processor configured to process signals from the PPG sensor to determine heart rate and RR-interval (RRi) for the subject, and to determine a heart rate pattern for the subject over a period of time. The at least one processor is configured to change a sampling frequency of the PPG sensor for determining RRi in response to the determined heart rate pattern. The at least one processor is configured to reduce the sampling frequency of the PPG sensor in response to determining a pattern of heart rate below a threshold.

Abstract: An ear-worn device includes a speaker, an optical emitter, an optical detector, a processor, and a housing configured to be positioned within an ear of a subject, wherein the housing encloses the speaker, optical emitter, optical detector, and processor. The housing includes at least one window that exposes the optical emitter and optical detector to the ear of the subject, and the housing includes at least one aperture through which sound from the speaker can pass. Light transmissive material is located between the optical emitter and the at least one window and is configured to deliver light emitted from the optical emitter to an ear region of the subject at one or more predetermined locations. Light transmissive material is positioned between the optical detector and the at least one window and is configured to collect light external to the housing and deliver the collected light to the optical detector.

Abstract: Methods and apparatus are described for facilitating the extraction of cleaner biometric signals from biometric monitors. A motion reference signal is generated independently from a biometric signal and then the motion reference signal is used to remove motion artifacts from the biometric signal.

Abstract: An earbud includes a speaker driver, and a sensor module secured to the speaker driver that is configured to detect and/or measure physiological information from a subject wearing the earbud. The sensor module includes a printed circuit board, an optical source secured to the printed circuit board, and an optical detector secured to the printed circuit board. A first light guide may be coupled to the optical source that is configured to deliver light from the optical source into an ear region of the subject via a distal end thereof. A second light guide may be coupled to the optical detector that is configured to collect light from the ear region via a distal end thereof and deliver collected light to the optical detector. One or more additional sensors may be secured to the speaker driver, such as accelerometers, humidity sensors, altimeters, and temperature sensors.

Abstract: An optical sensor module for detecting and/or measuring physiological information that can be integrated into a wearable device, such as a headset, a wristband, a ring, etc., includes a housing supporting an optical source and an optical detector. The housing overlies the optical source and optical detector and includes a first light guide comprising light transmissive material in optical communication with the optical source and a second light guide comprising light transmissive material in optical communication with the optical detector. The first and second light guides define respective first and second axial directions that are outwardly diverging. When the sensor module is in use and placed adjacent the skin of a user, light rays emanating from the optical source and directed into the skin of the user cannot overlap with light rays returning through the skin of the user.

Abstract: A sensor module includes a housing and a sensor assembly disposed within the housing. The sensor assembly includes a base having at least one energy emitter and at least one energy detector, and a guide layer overlying the base in face-to-face relationship. The guide layer has at least one protrusion extending outwardly to accommodate the at least one energy emitter, and a plurality of outwardly extending stabilizing members. The housing has at least one first opening through which the at least one protrusion extends, and a plurality of second openings through which the stabilizing members extend. Some of the stabilizing members have an outwardly extending length that is greater than an outwardly extending length of the at least one protrusion.
