Abstract
Abstract An estrus detection system using a transponder mounted to an animal and including a motion sensor. The motion sensor produces a series of pulses as a function of movement. A counting circuit is energized by the sensor. A storage circuit retains the count together with an identification code unique to the animal. The transponder is interrogated to receive data and such is processed to determine estrus.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
97 words
A detection system for an animal comprising: a transponder mounted to the animal, said transponder including transducer means responsive to movement of the animal to generate a series of electrical pulses, first circuit means receiving said electrical pulses and generating a count indication of animal movement, second circuit means receiving said electrical pulses and storing electrical energy for driving said first circuit means, and means for storing said count together with an identification code unique to said animal, means for interrogating said transponder to receive data therefrom; and process means for receiving data from said interrogator means.
Claim 2
Dependent Claim
97 words
A detection system for an animal comprising: a transponder mounted to the animal, said transponder including transducer means responsive to movement of the animal to generate a series of electrical pulses, first circuit means receiving said electrical pulses and generating a count indication of animal movement, second circuit means receiving said electrical pulses and storing electrical energy for driving said first circuit means, and means for storing said count together with an identification code unique to said animal, means for interrogating said transponder to receive data therefrom; and process means for receiving data from said interrogator means.
Claim 3
Dependent Claim
37 words
