Abstract

One or more items of apparel have a plurality of sensors (10, 11, and 12) disposed therein (either permanently or temporarily). These sensors sense physical states of the individual wearing the items of apparel and/or of the local environment. In one embodiment, multiple sensors sense, in alternative ways, a parameter that corresponds to a physical state of interest. Information from these alternative sensing approaches is co-processed to yield a resultant parameter value that can be used in various ways. In one embodiment, the parameter value is locally or remotely displayed. In one embodiment, the parameter value is used in comparison against risk thresholds to ascertain a degree of risk to the individual.

Claims

1. An apparatus comprising:

at least one item of apparel;

a plurality of sensors disposed within the at least one item of apparel, wherein at least two of the plurality of sensors each sense, in alternative ways, a same parameter that corresponds to a given physical state.

2. The apparatus of claim 1 wherein the at least two of the plurality of sensors are disposed within one of the at least one item of apparel.

3. The apparatus of claim 1 wherein the at least one item of apparel comprises at least one of headgear, a torso covering, a glove, footwear, pants, a dress, an apron, a belt, suspenders, and an undergarment.

4. The apparatus of claim 1 wherein at least one of the plurality of sensors is readily removable from the at least one item of apparel such that the at least one item of apparel can be laundered without the at least one of the plurality of sensors.

5. The apparatus of claim 1 wherein the given physical state comprises at least one of human blood pressure, pulse rate, temperature, respiration rate, blood oxygen, movement, and vertical bearing.

6. The apparatus of claim 1 wherein the given physical state comprises at least one of environmental temperature and environmental content.

7. The apparatus of claim 6 wherein the environmental content includes at least one of carbon monoxide, carbon dioxide, toxic gases, explosive gases, and biohazards.

8. The apparatus of claim 1 wherein at least some of the plurality of sensors sense information as a function of at least one of sound, ultrasonic sound, voltage potential, infrared, ultraviolet, temperature, and pressure, radar, electromagnetism, and laser light.

9. The apparatus of claim 1 and further comprising a radio transmitter operably coupled to at least some of the plurality of sensors, wherein the radio transmitter is disposed within the at least one item of apparel.

10. The apparatus of claim 1 and further comprising a user interface having at least one of a display and an audible alarm operably coupled to at least one of the plurality of sensors, wherein the user interface is supported by the at least one item of apparel.

11. The apparatus of claim 1 and further comprising a processing unit that is operably coupled to the at least two of the plurality of sensors and wherein the processing unit is disposed within the at least one item of apparel.

12. The apparatus of claim 11 wherein the processing unit is operably coupled via a physical link to at least one of the at least two of the plurality of sensors.

13. The apparatus of claim 11 wherein the processing unit is operably coupled via a wireless link to at least one of the at least two of the plurality of sensors.

14. A method comprising:

disposing a plurality of sensors within apparel as worn by an individual, wherein the plurality of sensors includes at least two sensors that each differently senses a same given physical state;

processing information from a plurality of the at least two sensors to develop information regarding the given physical state.

15. The method of claim 14 wherein including at least two sensors that each differently senses a given physical state includes including at least two sensors that each differently senses a given physical state using alternative sensing techniques.

16. The method of claim 15 wherein disposing a plurality of sensors within apparel as worn by an individual, wherein the plurality of sensors includes at least two sensors that each differently senses a given physical state includes disposing a plurality of sensors within apparel as worn by an individual, wherein the plurality of sensors includes at least two sensors that each differently senses a given physical state that comprises at least one of human blood pressure, human pulse rate, human temperature, human respiration rate, human blood oxygen, human vertical bearing, human movement, environmental temperature, environmental toxic gases, environmental explosive gases, environmental carbon monoxide, environmental carbon dioxide, and environmental biohazards.

17. The method of claim 15 wherein processing information from a plurality of the at least two sensors to develop information regarding the given physical state includes processing the information within the apparel.

18. The method of claim 17 and further comprising wirelessly transmitting at least some of the information.

19. The method of claim 18 wherein wirelessly transmitting includes wirelessly transmitting at least some of the information only a relatively short distance.

20. The method of claim 18 wherein wirelessly transmitting includes using at least one of infrared transmission and radio frequency transmission.

21. The method of claim 14 wherein processing information from a plurality of the at least two sensors to develop information regarding the given physical state includes using a profile of data that corresponds to an individual who is wearing the apparel.

22. The method of claim 14 and further comprising displaying at least a portion of the information proximal to the apparel.

23. The method of claim 14 wherein disposing a plurality of sensors within apparel as worn by an individual includes disposing a plurality of sensors within apparel as worn by an individual such that the plurality of sensors do not physically contact skin of the individual.

24. An article of apparel having:

multiple sensor means disposed in the article of apparel for sensing, in alternative ways, a same physical state;

processing means disposed in the article of apparel and being operably coupled to the multiple sensor means for processing signals from the multiple sensor means and for providing information regarding the physical state as a function of each of the multiple sensor means.

25. The article of apparel of claim 24 and further including transmission means for transmitting at least some of the information regarding the physical state.

26. The article of apparel of claim 24 and further including display means operably coupled to the processing means for displaying at least some of the information regarding the physical state.

27. The article of apparel of claim 24 wherein processing signals from the multiple sensor means further includes comparing sensing sensor information with at least one predetermined threshold.

28. The article of apparel of claim 27 wherein processing signals further includes providing an alarm when the sensor information exceeds the at least one predetermined threshold.

29. The article of apparel of claim 27 wherein processing signals further includes providing a display of information when the sensor information exceeds the at least one predetermined threshold.

30. The article of apparel of claim 24 and further comprising wireless transmission means for wirelessly transmitting at least some information that corresponds to the signals from the multiple sensor means.
