Apparatus and Methods for Monitoring Physiological Data During Environmental Interference

摘要

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.

主权项

1. A monitoring apparatus, comprising:
a housing configured to be attached to a body of a subject; and a sensor module disposed within the housing, the sensor module comprising: a printed circuit board (PCB); a detector attached to the PCB that detects an energy response signal from the subject in response to modulated energy directed upon a target region of the subject, wherein the energy response signal is associated with a physiological condition of the subject; a filter that attenuates time-varying environmental interference from the energy response signal, wherein the time-varying environmental interference is from a non-physiological source external to the body of the subject and includes one or more of the following: sunlight, ambient light, airflow, and temperature; and at least one processor that controls operations of the detector and/or filter, and that is configured to process the detected energy response signal and produce an extracted energy response signal.
