Abstract

A frostbite warning system for monitoring conditions adjacent a portion of a user, including an article of clothing that is configured to be disposed on the portion of the user'"'"'s body, a temperature sensor that is configured to detect a temperature within the article of clothing and produce a first input signal that is indicative of the temperature within the article of clothing, a processor configured to receive the first input signal, compare the temperature in the article of clothing to a threshold temperature at which a first warning signal is produced, and produce the first warning signal when the temperature within the article of clothing is equal to or less than the threshold temperature.

Claims

1. A frostbite warning system for monitoring conditions adjacent a portion of a user, comprising:

an article of clothing that is configured to be disposed on the portion of the user'"'"'s body;

a temperature sensor that is configured to detect a temperature within the article of clothing adjacent the portion of the user'"'"'s body that is disposed within the article of clothing and produce a first input signal that is indicative of the temperature within the article of clothing;

a programmable logic controller configured to receive the first input signal, compare the temperature in the article of clothing to a threshold temperature at which a first warning signal is produced, and produce the first warning signal when the temperature within the article of clothing is equal to or less than the threshold temperature;

an audible indicator, wherein the first warning signal from the programmable logic controller causes the audible indicator to provide an audible indication to the user and the audible indicator is one of a pair of ear buds, a pair of headphones, and a speaker; and

a moisture sensor that is configured to detect a moisture level within the article of clothing adjacent the portion of the user'"'"'s body that is disposed in the article of clothing and produce a second input signal that is indicative of the moisture level within the article of clothing,

wherein the programmable logic controller is further configured to receive the second input signal compare the moisture level in the article of clothing to a threshold moisture level at which a second warning signal is produced, and produce the second warning signal when the moisture level within the article of clothing equals or exceeds the threshold moisture level.

2. The frostbite warning system of claim 1, wherein the second warning signal from the programmable logic controller causes the audible indicator to provide an audible indication to the user.

3. The frostbite warning system of claim 2, further comprising a visual indicator, wherein the first warning signal and the second warning signal from the programmable logic controller causes the visual indicator to provide a visual indication to the user.

4. The frostbite warning system of claim 3, wherein the visual indicator is one or more light emitting diodes.

5. The frostbite warning system of claim 1, wherein the article of clothing is one of a mitten, a glove, a sock, and a hat.
