Abstract

An ear wearable or head wearable environmental information and physiological information monitoring device is introduced. This system is capable of transmitting and receiving information wirelessly. This system also comprises of a wireless display unit that can be attached to a hand band.

Claims

1. Wearable body core temperature measuring system with an ear canal insert type thermal sensors or trans-virginal temperature sensors having a signal processing, signal conditioning, information feed back, control signal feed back, power supply and display units are in an ear wearable embodiment.

2. A device according to claim 1 having a signal processing unit, signal feed back unit, and display unit are in the same embodiment/s that cam be clipped to user wearable garment such as a cap, a hat, a head band, a shirt, an underwear, a jacket or trouser.

3. A device according to the claim 1 or claim 2 having an external base station such as a computer (PC), PDA, mobile phone, wrist worn watch or a wearable display unit for monitoring, processing, displaying and generating alarms and generating audio or visual feed back to the wearer.

4. A devices according claim 1 or claim 2 or claim 8 or claim 9 having a signal feed back unit comprises of audio feedback speaker.

5. Use of a device according to claim 1 or claim 2 or claim 3 to monitor basal temperature of women and providing the feed back for monthly ovulation cycle and best time for conception.

7. A device according to the above claim 1 or claim 2 or claim 3 or claim 4 or claim 5 having a memory so that the temperature can be stored and downloaded to an external device such as a PDA or a PC.

17. A device according to claim 1 or claim 2 or claim 3 or claim 8 or claim 9 having additional environmental information monitoring sensors such as air quality, radiation, geographical location, position, direction, temperature and humidity.

18. A system comprises of a device according to claim 1 or claim 2 or claim 3 or claim 8 or claim 9 and a wireless environmental information monitoring device such as air quality, radiation, geographical location, position, direction, temperature and humidity.

19. A device according to claim 8 or claim 9 or claim 1 or claim 2 or claim 3 having microphone for audio communication and a ear canal insert temperature sensor for the body core temperature measurement.

6. The audio visual feed back to the wearer is achieved by the means of temperature information and the level of the temperature stating normal, low or high.

8. An ear wearable or a head wearable respiration information monitoring system that measures the respiration information of a mammal via the temperature change of the inhale and exhale air, or the temperature difference of the surface of the lips or the mouth or inner or outer surface of the nose of a mammal, or the humidity variation of the inhale and exhale air, or the gas concentrations variation of the inhale and exhale air.

9. A system according to claims 8 having a wire or wireless information transmission unit that transmits the respiration information including but not limited to breath temperature, inhaling duration, inhaling dept, inhaling gas concentrations, exhaling duration, exhaling depth, exhaling gas concentrations, mouth breathing, mouth breathing duration and depth, nasal breathing depth, nasal breathing duration, respiration rate (number of breadths per minute), breath flow rate and humidity of the inhale and exhale air to the display, recording, processing unit.

10. The gas concentrations variation of the inhale and exhale air of the claim 8 is carbon dioxide or carbon monoxide or oxygen or gases with nitrogen compound.

11. A sensor system according to claim 8 having a display unit or audio unit for the audio visual feedback information to the wearer.

12. A system according to claim 8 where the system can be attached onto or embedded into wearable apparatus including;
