Abstract:
A method of controlling a biometric parameter, such as heart rate and/or breathing rate, of a subject engaged in an activity includes sensing the biometric parameter via a monitoring device worn by the subject, determining frequency characteristics of the biometric parameter, and presenting to the subject musical audio having a tempo correlated to the frequency characteristics of the biometric parameter. The tempo of the musical audio presented to the subject may be changed in order to cause a change in the biometric parameter. A method of modulating heart rate of a subject engaged in an activity includes sensing a breathing rate of the subject via a monitoring device worn by the subject, and then presenting to the subject musical audio having a tempo selected to change the breathing rate by an amount sufficient to cause a change in the heart rate.
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:
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:
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 method of generating a data string containing physiological and motion-related information includes sensing physical activity of a subject via at least one motion sensor attached to the subject, sensing physiological information from the subject via at least one photoplethysmography (PPG) sensor attached to the subject, and processing signals from the at least one motion sensor and signals from the at least one PPG sensor into a serial data string of physiological information and motion-related information. A plurality of subject physiological parameters can be extracted from the physiological information, and a plurality of subject physical activity parameters can be extracted from the motion-related information. The serial data string is parsed out such that an application-specific interface can utilize the physiological information and motion-related information for an application that generates statistical relationships between subject physiological parameters and subject physical activity parameters in the physiological information and motion-related information.

Abstract:
A method of monitoring a subject via an earbud module includes positioning the earbud module within an ear of the subject such that a sensor region thereof matingly engages a region of the ear at the intersection of the anti tragus and acoustic meatus and is oriented in a direction away from the ear canal. Physiological information is then detected and/or measured via the optical sensor. The optical sensor includes an optical emitter and an optical detector, and detecting and/or measuring physiological information about the subject includes directing optical energy at the ear region via the optical emitter and detecting optical energy absorbed, scattered, and/or reflected by the ear region via the optical detector. Environmental information in a vicinity of the subject may be monitored via an environmental sensor associated with the earbud module and subject motion may be monitored via a motion sensor associated with the earbud module.
