Abstract
A system and method for monitoring the health of an animal using multiple sensors is described. The wearable device may include one or more sensors whose resultant signal levels may be analyzed in the wearable device or uploaded to a data management server for additional analysis. One or more embodiments include variations of the sensor system to determine whether the wearable device is being worn properly by the animal so that the resultant signal levels are of optimal quality.
Claims6
A wearable device for an animal comprising:
- a housing;
- an accelerometer configured to track a tri-axial acceleration of the animal and output the tracked tri-axial acceleration as signals including a first axis acceleration signal relating to a first axis, a second axis acceleration signal relating to a second axis, and a third axis acceleration signal relating to a third axis;
- a memory storing computer-readable instructions;
- and
- a processor configured to execute the computer-readable instructions to perform processing steps including:
- receiving the first axis acceleration signal from the accelerometer;
- receiving the second axis acceleration signal from the accelerometer;
- receiving the third axis acceleration signal from the accelerometer;
- determining an acceleration vector from a combination of the first axis acceleration signal, the second axis acceleration signal, and the third axis acceleration signal;
- correlating the first axis acceleration signal, the second axis acceleration signal, and the third axis acceleration signal with the acceleration vector;
- and
- generating an alert signal when at least one of the three axis acceleration signals does not correlate with the acceleration vector,
- wherein the alert signal relates to a fit quality of the wearable device based on a lack of correlation of the acceleration vector with each of the three axis acceleration signals.
