Abstract

Systems and methods for monitoring various physiological and environmental factors, as well as systems and methods for using this information for a plurality of useful purposes, are provided. Real-time, noninvasive health and environmental monitors include a plurality of compact sensors integrated within small, low-profile devices. Physiological and environmental data is collected and wirelessly transmitted into a wireless network, where the data is stored and/or processed. This information is then used to support a variety of useful methods, such as clinical trials, marketing studies, biofeedback, entertainment, and others.

First claim

That which is claimed is:

1. A monitoring apparatus configured to be worn by a subject, wherein the apparatus comprises:
at least one physiological sensor configured to detect physiological information from the subject;
at least one environmental exposure sensor configured to detect at least one airborne analyte in a vicinity of the subject;
at least one motion sensor; and
at least one processor, wherein the at least one processor is configured to:
process signals produced by the at least one environmental exposure sensor and calculate a volumetric concentration of the least one airborne analyte,
process signals produced by the at least one physiological sensor to determine a physiological response of the subject to the at least one airborne analyte,
calculate a distance traveled by the subject via signals produced by the at least one motion sensor, and
calculate a volume of air to which the subject has been exposed using the distance traveled by the subject,
wherein calculating the volumetric concentration of the least one airborne analyte is based on the volume of air to which the subject has been exposed.

2. The apparatus of claim 1 , wherein the at least one motion sensor comprises at least one accelerometer, pedometer, or gyroscope.

3. The apparatus of claim 1 , wherein the at least one environmental exposure sensor comprises at least one airflow sensor.

4. The apparatus of claim 1 , further comprising a transmitter responsive to the processor that is configured to transmit the volumetric concentration of the least one airborne analyte and the physiological response of the subject to a remote device and/or portable telecommunication device.

5. The apparatus of claim 1 , wherein the monitoring apparatus comprises a headset configured to be attached to an ear of the subject.

6. The apparatus of claim 1 , wherein the at least one airborne analyte comprises breathable toxicants.

7. The apparatus of claim 1 , wherein the at least one airborne analyte comprises a volatile organic chemical (VOC), a hydrocarbon, a polycyclic aromatic hydrocarbon (PAH), a carcinogen, or a toxin.

8. The apparatus of claim 1 , wherein the at least one airborne analyte comprises an airborne particle of at least one of oil, metal shavings, dust, smoke, ash, mold, or biological contaminates.

9. The apparatus of claim 1 , wherein the physiological response of the subject comprises heart rate.

10. A monitoring system, comprising:
a monitoring apparatus configured to be worn by a subject, wherein the apparatus comprises:
at least one physiological sensor configured to detect physiological information from the subject; and
at least one environmental exposure sensor configured to detect at least one airborne analyte in a vicinity of the subject;
at least one motion sensor; and
a remote device comprising at least one processor in telemetric communication with the monitoring apparatus, wherein the at least one processor is configured to:
process signals produced by the at least one environmental exposure sensor and calculate a volumetric concentration of the least one airborne analyte,
process signals produced by the at least one physiological sensor and determine a physiological response of the subject to the at least one airborne analyte,
calculate a distance traveled by the subject via signals produced by the at least one motion sensor, and
calculate a volume of air to which the subject has been exposed using the distance traveled by the subject,
wherein calculating the volumetric concentration of the least one airborne analyte is based on the volume of air to which the subject has been exposed.

11. The system of claim 10 , wherein the at least one motion sensor comprises at least one accelerometer, pedometer, or gyroscope.

12. The system of claim 10 , wherein the at least one environmental exposure sensor comprises at least one airflow sensor.

13. The system of claim 10 , wherein the monitoring apparatus comprises a headset configured to be attached to an ear of the subject.

14. A method of monitoring a physiological response of a subject to an environmental condition in a vicinity of the subject, wherein the subject is wearing a telemetric headset, the telemetric headset comprising at least one physiological sensor, at least one environmental sensor, at least one motion sensor, and at least one processor, the method comprising:
sensing environmental exposure information in the vicinity of the subject via the at least one environmental sensor;
processing the environmental exposure information via the at least one processor to calculate a volumetric concentration of at least one airborne analyte in a vicinity of the subject;
determining a physiological response of the subject to the at least one airborne analyte via the at least one physiological sensor;
sensing subject motion via at least one motion sensor associated with the telemetric headset, and calculating a distance traveled by the subject via the at least one processor using signals produced by the at least one motion sensor;
calculating, via the at least one processor, a volume of air to which the subject has been exposed using the distance traveled by the subject,

wherein calculating the volumetric concentration of the least one airborne analyte is based on the volume of air to which the subject has been exposed.

15. The method of claim 14 , wherein the at least one environmental exposure sensor comprises at least one airflow sensor.

16. The method of claim 14 , wherein the at least one motion sensor comprises at least one accelerometer, pedometer, or gyroscope.
