1. A monitor system for monitoring at least one condition of an animal in an extreme environment, comprising:
- at least one physiological sensor to measure at least one physiological measurement from the animal;
at least one environmental sensor to measure at least one environmental measurement from a region near the animal;
at least one processor;
a database comprising;
at least one threshold value, wherein the at least one threshold value comprises a maximum safe value of the at least one condition of the animal, and wherein the at least one threshold value is a function of at least one condition of the animal; and
at least one data quality criterion; and
an application executed by the processor to;
select a subset of the at least one physiological measurement and the at least one environmental measurement based on the at least one data quality criterion;
calculate the at least one condition of the animal using the subset of the at least one physiological measurement and the at least one environmental measurement;
retrieve the at least one threshold value;
compare the at least one condition of the animal to the at least one threshold value, wherein each threshold value comprises the maximum safe value of each of the at least one conditions of the animal; and
produce an alarm signal if the at least one condition of the animal exceeds the at least one threshold value.

8. A method for monitoring at least one condition of an animal in an extreme environment, comprising:
-
receiving at least one physiological measurement from the animal; receiving at least one environmental measurement from a region near the animal; selecting a subset of the at least one physiological measurement and the at least one environmental measurement based on at least one data quality criterion; retrieving at least one threshold value from a memory of at least one processor, wherein the at least one threshold value comprises the maximum safe value of the at least one condition of the animal, and wherein the at least one threshold value is a function of at least one condition of the animal; calculating at least one condition of the animal using the subset of the at least one physiological measurement and the at least one environmental measurement; comparing the at least one condition of the animal to the at least one threshold value, wherein each threshold value comprises the maximum safe value of each of the at least one conditions of the animal; and producing an alarm signal if the at least one condition of the animal exceeds the at least one threshold value. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for monitoring at least one condition of an animal in an extreme environment, comprising:
-
receiving a skin temperature and an accelerometer reading from the animal; receiving an ambient temperature and a relative humidity from a region near the animal; calculating an activity level of the animal by comparing the accelerometer reading to an animal activity rule; retrieving a maximum core temperature, wherein the maximum core temperature is a function of the animal activity level; calculating a core temperature by substituting the skin temperature into a core temperature rule; calculating a heat index by substituting the ambient temperature and relative humidity into a heat index rule; retrieving a maximum heat index; and producing an alarm signal if the core temperature is greater than or equal to the maximum core temperature and/or the heat index is greater than or equal to the maximum heat index. - View Dependent Claims (16, 17, 18)
