Abstract

Wearable apparatus for monitoring various physiological and environmental factors are provided. Real-time, noninvasive health and environmental monitors include a plurality of compact sensors integrated within small, low-profile devices, such as earpiece modules. Physiological and environmental data is collected and wirelessly transmitted into a wireless network, where the data is stored and/or processed.

Claims

1. A headset, comprising:

a housing configured to be attached to an ear of a person so as to be positioned outside an ear canal of the ear;

a first audio sensor within the housing, wherein the first audio sensor comprises a speaker configured to provide sound transmission from a source into the ear canal, to detect auscultatory sounds from the ear canal, and to generate a physiological information signal from the auscultatory sounds;

a second audio sensor within the housing and oriented in a direction towards an outside environment of the person, wherein the second audio sensor is configured to detect sounds external to the person including voice sounds, footstep sounds, coughing and sneezing sounds from people in a vicinity of the person, and to generate an environmental information signal from the external sounds;

an acoustical buffer located between the first and second audio sensors; and

at least one processor configured to receive the physiological information signal and the environmental information signal, wherein the at least one processor is configured to identify the external sounds in the physiological information signal and the environmental information signal, and wherein the at least one processor is configured to digitally process the physiological information signal to reduce the voice sounds, footstep sounds, coughing sounds and sneezing sounds from the physiological information signal and generate a cleaner physiological information signal.

2. The headset of claim 1, wherein the speaker is configured to detect auscultatory sounds from the person having a frequency of less than 1,000 Hz.

3. The headset of claim 1, wherein the physiological information signal comprises information regarding internal sounds of at least one of pulse rate, breathing rate, or swallowing rate.

4. The headset of claim 1, wherein the speaker is configured to detect auscultatory sounds from a tympanic membrane in the ear of the person.

5. The headset of claim 1, further comprising at least one transmitter configured to wirelessly transmit the physiological information signal to a remote device.

6. The headset of claim 1, wherein the headset comprises an earpiece fitting, and wherein the first audio sensor is located within the earpiece fitting.
