| Abstract: |
An electronic estrus detector that may be affixed to the back of a cow comprises a tapeswitch connected to a counter for storage and display of number of mounts by another cow. When a cow mounts another cow equipped with the estrus detector, the impact of the mounting cow upon the monitored cow closes the tapeswitch and increments the counter, such that the contents of the counter indicate the estrus condition of the monitored cow.
In a second embodiment, a modified electronic estrus detector indicates estrus condition based upon satisfaction of a mount-second index. A user programs the estrus detector to shwo when a specified number of mounts, coupled with a specified total time duration of all mounts, has occured.

First Claim:
Show all 13 claims |
I claim:
1. An estrus detector for detecting estrus in animals that manifest onset of estrus by standing for estrus mounting activity by another animal, comprising:
- means for sensing estrus mounts including means for generating estrus mount signals;
- means for processing said estrus mount signals, including:
- means for numerically summing and storing sensed estrus mounts;
- means for programming a desired sum of sensed estrus mounts;
- means for detecting and storing the approximate time elapsed during a sensed estrus mount as an estrus mount time;
- means for summing the estrus mount times for all sensed estrus mounts;
- means for programming a desired sum of all estrus mount times;
- means for determining that a first condition has been satisfied, wherein said first condition is that the sum of sensed estrus mounts is at least equal to the desired sum of sensed estrus mounts;
- means for determining that a second condition has been satisfied, wherein said second condition is that the sum of all estrus mount times is at least equal to the desired sum of all estrus mount times; and
- indicating means, including means for indicating that both said first and second conditions have been satisfied.
