PHYSIOLOGICAL MONITORING METHODS
First Claim
1. A method of monitoring a subject via a headset, wherein the headset includes an earbud housing that encloses at least one optical emitter and at least one optical detector, and light transmissive material external to the earbud housing that is in optical communication with the at least one optical emitter and the at least one optical detector via at least one window in the earbud housing, the method comprising:
- positioning the earbud housing within an ear of the subject;
delivering light from the at least one optical emitter through the at least one window and into an ear region of the subject at one or more predetermined locations via the light transmissive material; and
collecting light external to the earbud housing and delivering the collected light through the at least one window to the at least one optical detector via the light transmissive material.

Abstract
A monitoring device includes a housing configured to be attached to a body of a subject. An optical emitter, optical detector, and sensor for measuring motion noise are located within the housing. Light transmissive material is in optical communication with the optical emitter and detector and is configured to deliver light from the optical emitter to one or more locations of the body of the subject and to collect light external to the housing and deliver the collected light to the detector. A signal processor is configured to receive and process signals produced by the optical detector and the motion noise sensor, and to remove noise from the signals produced by the optical detector. The signal processor may generate physiological parameters for the subject such as heart rate, blood flow, blood pressure, VO2max, heart rate variability, respiration rate, and blood gas/analyte level.

13. A method of monitoring a subject via a monitoring device, wherein the monitoring device includes a band having at least one optical emitter and at least one optical detector, wherein the band includes an outer body portion and an inner body portion secured together in concentric relationship, wherein the inner body portion includes light transmissive material and has outer and inner surfaces, wherein a layer of cladding material is positioned near the inner body portion inner surface, and wherein at least one window is formed in the cladding material, the method comprising:
-
encircling a portion of the body of the subject with the band; delivering light from the at least one optical emitter via the light transmissive material and the at least one window to one or more locations of the body of the subject; and collecting light from one or more locations of the body of the subject via the at least one window and delivering the collected light to the at least one optical detector via the light transmissive material. - View Dependent Claims (14, 15, 16, 17)

18. A method of monitoring a subject via a monitoring device, wherein the monitoring device includes a base having at least one optical emitter and at least one optical detector, a layer of light transmissive material attached to the base and having outer and inner surfaces, a layer of cladding material at the outer surface of the layer of light transmissive material, and at least one window formed in the layer of cladding material, the method comprising:
-
adhesively securing the monitoring device to a body of the subject; delivering light from the at least one optical emitter via the light transmissive material and the at least one window to one or more locations of the body of the subject; and collecting light from one or more locations of the body of the subject via the at least one window and delivering the collected light to the at least one optical detector via the light transmissive material. - View Dependent Claims (19, 20, 21)
