Always on headwear recording system
View Patent ↗A system that records audio and stores the recording is provided. The system includes first and second monitoring assemblies mounted in an earpiece that occludes and forms an acoustic seal of an ear canal. The first monitoring assembly includes an ambient sound microphone (ASM) to monitor an ambient acoustic field and produce an ASM signal. The second monitoring assembly includes an ear canal microphone (ECM) to monitor an acoustic field within the ear canal and produce an ECM signal. The system also includes a data storage device configured to act as a circular buffer for continually storing at least one of the ECM signal or the ASM signal, a further data storage device and a record-activation system. The record-activation system activates the further data storage device to record a content of the data storage device.
1. An analysis system comprising:
at least one monitoring assembly mounted in an earpiece, the at least one monitoring assembly including at least one microphone to monitor an acoustic field proximate the earpiece, the at least one microphone producing at least one microphone signal responsive to the acoustic field;
a data storage device configured to act as a circular buffer for continually buffering the at least one microphone signal; and
an audio analysis system configured to analyze a content of the circular buffer,
wherein the audio analysis system is configured to analyze the content of the circular buffer to detect at least one of a speech sound, a non-speech sound or a transient sound.
2. The analysis system according to claim 1 , wherein the speech sound includes a verbal activation message.
3. The analysis system according to claim 1 , wherein the audio analysis system is configured to analyze the content of the circular buffer over a predetermined time period responsive to at least one of a predetermined detected sound or a user indication.
4. The analysis system according to claim 1 , wherein the audio analysis system is configured to analyze the content of the circular buffer to detect at least one sound indicative of an accident or an emergency event.
5. The analysis system according to claim 4 , wherein when the accident is detected, the analysis system automatically transmits an indication to a remote location that a user of the earpiece has been involved in the accident.
6. The analysis system according to claim 1 , wherein the earpiece includes first and second earpieces, each of the first and second earpieces being coupled to the data storage device.
7. The analysis system according to claim 1 , wherein the data storage device is configured to receive at least one audio signal from a remote device.
8. The analysis system according to claim 7 , wherein the remote device includes at least one of a mobile phone, a media player, a computing device or a further earpiece.
9. The analysis system according to claim 8 , wherein the earpiece and the further earpiece are configured to be worn by a same user.
10. The analysis system according to claim 8 , wherein the earpiece and the further earpiece are configured to be worn by different users.
11. The analysis system according to claim 1 , wherein the at least one microphone includes a plurality of microphones.
12. The analysis system according to claim 1 , wherein the earpiece is configured to occlude and form an acoustic seal of an ear canal.
13. The analysis system according to claim 12 , wherein the at least one monitoring assembly includes at least one of:
a first monitoring assembly including at least one Ambient Sound Microphone (ASM) to monitor an ambient acoustic field at an entrance to the ear canal occluded by the earpiece, the at least one ASM producing at least one ASM signal responsive to the ambient acoustic field, or
a second monitoring assembly including at least one ear canal microphone (ECM) to monitor an internal acoustic field within the ear canal occluded by the earpiece, the at least one ECM producing at least one ECM signal responsive to the internal acoustic field within the ear canal,
the data storage device continually storing at least one of the at least one ECM signal or the at least one ASM signal.
14. The analysis system according to claim 1 , wherein the audio analysis system is remotely coupled to the earpiece.
15. The analysis system according to claim 1 , further comprising:
a further data storage device coupled to the data storage device,
wherein the audio analysis system is configured to activate the further data storage device to record the content of the data storage device.
16. The analysis system according to claim 15 , wherein the audio analysis system is configured to analyze data stored on the further data storage device.
17. The analysis system according to claim 16 , wherein the audio analysis system includes a communication system configured to transmit at least one of the content of the circular buffer or the data stored on the further data storage device to a remote server for analysis of at least one of the content or the data.
18. The analysis system according to claim 17 , wherein the audio analysis system is configured to receive results of the analysis from the remote server.
19. The analysis system according to claim 18 , further comprising a text-to-speech translation system to translate the received results of the analysis from the remote server into speech.
20. The analysis system according to claim 15 , wherein the audio analysis system is configured to activate the further data storage device responsive to detection of at least one predetermined sound.
