METHOD AND DEVICE FOR DETECTING ESTRUS
First Claim
Patent Images
1. A method for detecting estrus in a cattle animal, comprising the steps of:
- sensing and accumulating acceleration level of said cattle animal, over a period of time, by an acceleration sensor, wherein the acceleration level is indicated by energy level of an acceleration signal produced by the acceleration sensor;
sensing, over a period of time, data indicative of eating performed by said cattle animal;
attenuating the energy level of the acceleration signal as the indication of eating is stronger, the energy attenuated acceleration signal identifying neutralized motion data;
extracting typical activity level of said animal based on said neutralized motion data; and
identifying abnormal behavior indicative of said estrus in said animal by comparing recently identified neutralized motion data with the extracted typical activity level.

Abstract
The present invention provides a method and device for detecting estrus in animal by sensing along time the motion of the animal and identifying when the sensed motion is not related to eating periods of the animal. Based on the sensed motion which is not related to eating periods the estrus in the animal is identified
