Abstract:
A monitoring device configured to be attached to a body of a subject includes a sensor configured to detect and/or measure physiological information from the subject, and a processor coupled to the sensor that is configured to receive and analyze signals produced by the sensor. The processor is configured to change signal analysis frequency and/or sensor interrogation power in response to detecting a change in subject activity, a change in subject stress level, a change in environmental conditions, a change in time, and/or a change in location of the subject.
Abstract:
An earbud (300) comprising a speaker driver and a sensor module secured to the speaker driver and electrically connected to the speaker driver, and wherein the sensor module is configured to detect and/or measure physiological information from a subject wearing the earbud. The sensor module may comprise a printed circuit board (PCB; 312) to which are secured an optical source (24) and an optical detector (26), a first light guide (40) coupled to the optical source, a second light guide (42) coupled to the optical detector, wherein the first light guide is configured to deliver light from the optical source into an ear region of the subject via a distal end thereof, and wherein the second light guide is configured to collect light from the ear region via a distal end thereof and deliver collected light to the optical detector.
Abstract:
Apparatus and methods for attenuating environmental interference are described. A wearable monitoring apparatus includes a housing configured to be attached to the body of a subject and a sensor module that includes an energy emitter that directs energy at a target region of the subject, a detector that detects an energy response signal - or physiological condition - from the subject, a filter that removes time-varying environmental interference from the energy response signal, and at least one processor that controls operations of the energy emitter, detector, and filter.
Abstract:
A monitoring device configured to be attached to the ear of a person includes a base, an earbud housing extending outwardly from the base that is configured to be positioned within an ear of a subject, and a cover surrounding the earbud housing. The base includes a speaker, an optical emitter, and an optical detector. The cover includes light transmissive material that is in optical communication with the optical emitter and the optical detector and serves as a light guide to deliver light from the optical emitter into the ear canal of the subject wearing the device at one or more predetermined locations and to collect light external to the earbud housing and deliver the collected light to the optical detector.
