Abstract
A system and method for monitoring the condition of a human, companion animal, or livestock animal in an extreme environment is disclosed. In particular, a system and method to process at least one environmental measurement and at least one physiological measurement to assess at least one condition of a human, companion animal, or livestock animal in an extreme environment is disclosed.
Claims19
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;
- and
- 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
- an application executed by the processor to:
- calculate the at least one condition of the animal by combining 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.
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;
- 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 by combining 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.
The system of claim 14, wherein at least one data quality criterion comprises a range of valid data values, a maximum variance of the data, and a minimum data measurement rate.
The system of claim 14, wherein subset of the at least one physiological measurement and the at least one environmental measurement may be selected to eliminate redundant measurements.
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;
- retrieving a maximum core temperature, wherein the maximum core temperature is a function of an animal activity level;
- calculating the activity level of the animal by comparing the accelerometer reading to an animal activity rule;
- calculating a core temperature by substituting the skin temperature into a core temperature rule;
- producing an alarm signal if the core temperature is greater than or equal to the maximum core temperature.
