Abstract: A monitoring device includes a band capable of at least partially encircling a portion of a body of a subject. An optical source and an optical detector are supported by the band. A first light guide is in optical communication with the optical source and a second light guide is in optical communication with the optical detector. A distal end of the first light guide is configured to deliver light from the optical source into the body, and a distal end of the second light guide is configured to collect light from the body and deliver collected light to the optical detector. The first and second light guides define respective first and second axial directions that diverge outwardly from the band such that light rays directed into the body via the first light guide cannot overlap with light rays collected by the second light guide.

Abstract: An ear worn device includes an optical source, an optical detector, and a housing supporting the optical source and optical detector. The housing is configured to be positioned within an ear of a subject and includes a first light guide in optical communication with the optical source and a second light guide in optical communication with the optical detector. A distal end of the first light guide is configured to deliver light from the optical source into the ear, and a distal end of the second light guide is configured to collect light from the ear and deliver collected light to the optical detector. The first and second light guides define respective first and second axial directions that are outwardly diverging such that light rays directed into the ear via the first light guide cannot overlap with light rays collected by the second light guide.

Abstract: A monitoring device configured to be attached to a subject includes a photoplethysmography (PPG) sensor configured to measure a plurality of physiological parameters from the subject, a motion sensor configured to detect an activity state of the subject, and a processor coupled to the PPG sensor and the motion sensor. The PPG sensor is configured to measure each physiological parameter in a respective one of a plurality of time intervals. The processor instructs the PPG sensor to measure a first one of the plurality of physiological parameters if the activity state is at or above a threshold, and to measure a second one of the plurality of physiological parameters if the activity state is below the threshold.

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: The methods and apparatuses presented herein determine and/or improve the quality of one or more physiological assessment parameters, e.g., response-recovery rate, based on biometric signal(s) and/or motion signal(s) respectively output by one or more biometric and/or motion sensors. The disclosed methods and apparatuses also estimate a user's stride length based on a motion signal and a determined type of user motion, e.g., walking or running. The speed of the user may then be estimated based on the estimated stride length.

Abstract: A method of monitoring a subject includes detecting subject head motion information via a microelectromechanical systems sensor associated with an earpiece worn by the subject, processing, via a processor associated with the earpiece, the head motion information to determine subject head displacement relative to an origin and to determine if the subject has fallen down and/or is not moving, and transmitting the processed head motion information to a remote device. The method further includes communicating corrective action to the subject from the remote device and/or communicating corrective action for the subject from the remote device to a third party. The earpiece may include an audio headset, a hearing aid, or an earpiece fitting.
