Monitoring and identifying laboratory animals through UWB and other digital sensory signatures
A method and system for the continuous monitoring of animal physiology in laboratory animal cages through the use of miniaturized sensors located throughout the cage and in various fashions including the ability to identify each rodent's digital sensory signature through data fusion and artificial intelligence.
1. A system comprising:
an enclosure;
at least two sensors, one of which is a UWB radar, located relative to the enclosure;
a processor configured to receive signals from the two sensors;
a memory configured to store information contained in the signals received by the processor; and
a feeding/watering station inside the enclosure, wherein the feeding/watering station comprises:
a water tube;
a bracket configured to be attached to the enclosure;
a paddle;
a pin attaching the paddle to the bracket;
a spring positioned to urge the paddle to pivot about the pin,
wherein the paddle is located below the water tube,
wherein the paddle further comprises a paddle switch activated by force applied to the paddle causing the paddle to pivot, about the pin, against the urging of the spring,
wherein UWB radar is located in the paddle and is activated based on activation of the paddle switch, and
wherein the processor is further configured to monitor, using signals from the UWB radar, a heart rate while an animal is activating the paddle switch.
2. The system according to claim 1 , wherein the enclosure is sized to accommodate two or more rodents.
3. The system according to claim 1 ,
wherein the processor is configured to determine a quality of the information from at least one of the sensors.
4. The system according to claim 3 ,
wherein the processor is configured to, when the information is determined to be a sufficient quality, store the information.
5. The system according to claim 3 ,
wherein the processor is further configured to, when the information is determined to be less than sufficient quality, store the information with information regarding the quality of the information.
6. The system according to claim 1 , wherein the processor is further configured to determine, from the signals from the UWB radar, heart rate variability.
7. The system according to claim 1 , wherein another of the at least two sensors is an ambient temperature sensor.
8. The system according to claim 1 , wherein another of the at least two sensors is an RFID sensor.
9. The system according to claim 1 , wherein another of the at least two sensors is an accelerometer.
10. The system according to claim 1 , wherein another of the at least two sensors is a urine analysis sensor.
11. The system according to claim 1 , wherein the processor is further configured to determine, from the signals from the UWB radar, blood pressure.
12. The system according to claim 1 , wherein the processor is further configured to:
based on the information having reached a high confidence factor, store the information.
13. The system according to claim 1 , wherein the processor is further configured to:
store the information and a confidence factor associated with the information.
14. The system according to claim 1 , wherein the processor is further configured to:
determine, using the signals from the UWB radar, whether an animal in the enclosure is deceased.
15. The system according to claim 1 , wherein the processor is further configured to:
determine, using the signals from the sensor other than the UWB radar, one or more environmental conditions.
