Abstract
Abstract A method and apparatus for detecting standing heat in cattle includes an electronic timer module connected to a membrane switch. The module includes a digital timer display, a mounting counter display, a flashing clock signal to indicate activation of the module, as well as audible and visible indicators. A oval-shaped sleeve includes a transparent pocket containing the timer module and membrane switch, and the sleeve is adapted to be adhered to the base of the tail of a cow. The membrane switch is adapted to be actuated by the weight of other cows attempting to mount the cow when in heat. The switch actuates the timer, the mounting counter, and the flashing clock display, and also actuates the audible and visible signals to warn the cattle owner that the cow is in heat, it indicate how long the cow has been in heat, and also how many times the cow has been mounted.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
171 words
An apparatus for detecting the onset of estrus in a cow, comprising: a pressure responsive switch means disposed to be actuated by mounting of the cow, timer means connected to be activated by said switch means in count up fashion, mounting counter means connected to be activated by said switch means in count up fashion to count the number of times the cow has been mounted, digital display means connected to said timer means and said mounting counter means and adapted to display directly the elapsed time after mounting of the cow and the number of times the cow has been mounted, signaling means connected to said switch means to emit a warning signal in response to activation of said timer means, and means for securing said switch means, said timer means, said mounting counter means, said digital display means, and said signaling means to the cow to provide direct indication from the cow of the elapsed time since initial mounting and the number of times the cow has been mounted.
Claim 2
Independent Claim
171 words
An apparatus for detecting the onset of estrus in a cow, comprising: a pressure responsive switch means disposed to be actuated by mounting of the cow, timer means connected to be activated by said switch means in count up fashion, mounting counter means connected to be activated by said switch means in count up fashion to count the number of times the cow has been mounted, digital display means connected to said timer means and said mounting counter means and adapted to display directly the elapsed time after mounting of the cow and the number of times the cow has been mounted, signaling means connected to said switch means to emit a warning signal in response to activation of said timer means, and means for securing said switch means, said timer means, said mounting counter means, said digital display means, and said signaling means to the cow to provide direct indication from the cow of the elapsed time since initial mounting and the number of times the cow has been mounted.
Claim 3
Dependent Claim
34 words
The apparatus of claim 1, further including sleeve means for securing and supporting said switch means, said timer means, said mounting counter means, said digital display means, and said signaling means on the cow.
Claim 4
Dependent Claim
32 words
The apparatus of claim 2, wherein said sleeve means includes a flexible base member adapted to be adhered over the spine of the cow adjacent to the base of the tail thereof.
Claim 5
Dependent Claim
37 words
The apparatus of claim 3, further including a sealable pocket joined to said base member and adapted to retain said switch means, said timer means, said mounting counter means, said digital display means, and said signaling means.
Claim 6
Dependent Claim
14 words
The apparatus of claim 1, wherein said switch means includes a flexible membrane switch.
Claim 7
Dependent Claim
31 words
The apparatus of claim 1, further including a modular housing, said timer means, said mounting counter means, said digital display means, and said signaling means being secured in said modular housing.
Claim 8
Dependent Claim
49 words
The apparatus of claim 6, wherein said base member includes a mesh material adapted to be adhered to livestock adhesive applied to the cow, and a pocket formed on said base member of transparent plastic material to retain said housing and provide direct visualization of said digital display means.
Claim 9
Dependent Claim
23 words
The apparatus of claim 7, wherein said digital display means includes a clock symbol adapted to flash to indicate operation of the apparatus.
Claim 10
Dependent Claim
34 words
The apparatus of claim 8, further including on-off switch means connected to selectively disable said signaling means while permitting continued operation of said timer means, said mounting counter means, and said digital display means.
Claim 11
Dependent Claim
25 words
The apparatus of claim 9, further including a plurality of vent holes in said pocket to facilitate broadcast of audible signals from said signaling means.
Claim 12
Dependent Claim
36 words
The apparatus of claim 9, further including an opening in said pocket to facilitate emplacement of said timer means, said digital display means, said counter means, said switch means, and said signaling means in said pocket.
Claim 13
Dependent Claim
31 words
The apparatus of claim 8, wherein said switch means is disposed in said pocket to be impinged upon by the weight of another cow mounting the cow equipped with the apparatus.
Claim 14
Dependent Claim
15 words
The apparatus of claim 1, wherein said signaling means includes audible and visible warning devices.
Claim 15
Independent Claim
153 words
A method for determining the onset and time of onset of estrus in a cow, comprising the steps of: providing a timer module having a count up timer, a mounting counter, a digital display, and a local signaling device, providing a membrane switch connected to actuate said timer module, securing said membrane switch adjacent over the spine of a cow adjacent to the base of the tail of the cow, with the timer module secured directly thereto, said membrane switch being disposed to be actuated by mounting of the cow by other cows in response to onset of estrus, said membrane switch activating said timer module to indicate directly from the cow the elapsed time after initial mounting of the cow and the number of times the cow has been mounted, and to activate said local signaling device to emit a warning of onset of estrus in the cow directly from the cow.
Claim 16
Independent Claim
153 words
A method for determining the onset and time of onset of estrus in a cow, comprising the steps of: providing a timer module having a count up timer, a mounting counter, a digital display, and a local signaling device, providing a membrane switch connected to actuate said timer module, securing said membrane switch adjacent over the spine of a cow adjacent to the base of the tail of the cow, with the timer module secured directly thereto, said membrane switch being disposed to be actuated by mounting of the cow by other cows in response to onset of estrus, said membrane switch activating said timer module to indicate directly from the cow the elapsed time after initial mounting of the cow and the number of times the cow has been mounted, and to activate said local signaling device to emit a warning of onset of estrus in the cow directly from the cow.
