Abstract: A monitoring device configured to be attached to a subject includes a photoplethysmography (PPG) sensor configured to detect/measure physiological information from the subject, and a processor configured to process the physiological information to detect subject stress, and to determine an origin of the subject stress. The processor can determine the origin of the subject stress by increasing a sampling rate of the PPG sensor to collect higher acuity physiological information. The processor also can determine the origin of the subject stress by processing data from the PPG sensor to determine whether the subject is likely to have atrial fibrillation. In response to determining that the subject is likely to have atrial fibrillation, the processor can increase a frequency of pulsing of an optical emitter of the PPG sensor and/or increase a sampling rate of the PPG sensor to collect higher acuity data for diagnosing that atrial fibrillation is truly occurring.

Abstract: A monitoring device includes a sensor band configured to be secured around an appendage of a subject, a sensing element secured to the sensor band, a second band configured to be secured to the appendage of the subject in adjacent, spaced-apart relationship with the sensor band, and at least one member connecting the sensor band and the second band. The sensor band has a first mass and the sensing element has a second mass that is less than the first mass. The sensing element is movably secured to the sensor band via a biasing element, and the biasing element is configured to urge the sensing element into contact with a portion of the appendage. The biasing element decouples motion of the sensor band from the sensing element, and the at least one member decouples motion between the sensor band and the second band.

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: A monitoring device configured to be attached to a body of a subject includes a physiological sensor configured to detect and/or measure physiological information from the subject, an activity sensor configured to sense physical activity information from the subject, an actuator configured to adjust stability of the monitoring device relative to the body of the subject, and a processor in communication with the activity sensor and the actuator. The processor is configured to process the physical activity information to detect a change in the physical activity of the subject and to control the at least one actuator to adjust the stability of the monitoring device relative to the body of the subject in response to detecting that a change in the physical activity of the subject has occurred.

Abstract: A monitoring device configured to be attached to a subject includes a sensor configured to detect and/or measure physiological information and a processor coupled to the sensor. The sensor includes at least one optical emitter and at least one optical detector. The processor receives and analyzes signals produced by the sensor, and the processor changes wavelength of light emitted by the at least one optical emitter in response to detecting a change in subject activity. For example, the processor instructs the at least one optical emitter to emit shorter wavelength light in response to detecting an increase in subject activity, and the processor instructs the at least one optical emitter to emit longer wavelength light in response to detecting an decrease in subject activity. Detecting a change in subject activity may include detecting a change in at least one subject vital sign and/or subject motion.

Abstract: An earpiece configured to be positioned within an ear canal of a subject includes a housing, a sensor assembly disposed within the housing, and a cover removably secured to a free end of the housing. The sensor assembly includes at least one optical emitter and at least one optical detector. The cover includes at least one light guide configured to guide light from the at least one optical emitter and/or guide light from the ear of the subject to the at least one optical detector. The cover also includes a plurality of stabilizing members extending outwardly from an outer surface of the cover adjacent the at least one light guide. The earpiece may also include at least one ear support fitting associated with the housing that is configured to stabilize the earpiece within the ear canal.

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.
