Patent number: 9675042Abstract: A system comprises a memory and a processor. The memory stores information about a milking stall where a dairy livestock is located at a first time, and a coordinate location of the dairy livestock at a second time. The processor is communicatively coupled to the memory and determines if the coordinate location of the dairy livestock at the second time is different than the milking stall where the dairy livestock is located at the first time. If the coordinate location where the dairy livestock is located at the second time is not the milking stall, the processor generates an error flag associated with the dairy livestock.Type: GrantFiled: July 25, 2016Date of Patent: June 13, 2017Assignee: Technologies Holdings Corp.Inventors: Parimal G. Rajkondawar, Roger K. Erdman, David A. Johnson, William S. Nelson, Paul D. Thompson, Gary C. Steingraber

Patent number: 9603342Abstract: A method for health monitoring comprises electronically receiving location information for a dairy livestock that is generated by a plurality of identification devices positioned in a pen that operate in conjunction with a tag worn by the dairy livestock. The method stores the location information associated with the dairy livestock, the location information comprising a location of the dairy livestock within the pen at each of a plurality of times during a first time period. The method determines, based on at least a portion of the stored location information, a turn index parameter indicating a number of times the particular dairy livestock reverses direction during the first time period. The method determines whether the particular dairy livestock is likely to be in estrus based at least in part upon whether the determined turn index parameter is in excess of a baseline turn index parameter by more than a predefined amount.Type: GrantFiled: January 6, 2015Date of Patent: March 28, 2017Assignee: Technologies Holdings Corp.Inventors: Parimal G. Rajkondawar, Roger K. Erdman, David A. Johnson, William S. Nelson, Paul D. Thompson

Patent number: 9603691Abstract: A method for estrus detection includes storing location information associated with a dairy livestock. This information includes coordinate locations of the dairy livestock within a free stall pen at each of a plurality of times during a time period including a first time and a second time. The coordinate locations comprise at least a first (X, Y, Z) location of the dairy livestock at the first time and a second (X, Y, Z) location of the dairy livestock at the second time. The method further includes determining, based on at least the first and second (X, Y, Z) locations, a turn index parameter indicating a number of times the dairy livestock reverses directions during the time period. The method further includes determining whether the dairy livestock is likely to be in estrus based at least in part upon whether the determined turn index parameter is in excess of a baseline turn index parameter by more than a first predefined amount.Type: GrantFiled: April 2, 2015Date of Patent: March 28, 2017Assignee: Technologies Holdings Corp.Inventors: Parimal G.
