  • Patent number: 11864528
    Abstract: A control arrangement and a control module for a milking position for milking a dairy animal includes a casing forming an inner space enclosing a printed circuit board incorporating a control system for controlling and supervising at least some functions of the milking position. A communication area is provided on a front side of the printed circuit board and communicates with the control system. The casing includes an inner front plate. The front side of the printed circuit board is attached to a rear side of the inner front plate by a transparent adhering substance so that a part of the printed circuit board projects from the rear side of the inner front plate. The inner front plate permits access to the communication area. The part of the printed circuit board is embedded in a block of plastic material.

  • Patent number: 11751537
    Abstract: A system and method for automatically matching a sensor device attached to an animal with an ID tag attached to the animal, wherein a reader device, located in or alongside a passage of an animal enclosure, transmits a signal toward the animal in the passage that triggers the ID tag to transmit ID information, and a monitoring device in communication with the reader device receives the ID information from the reader device, receives sensor device information from the sensor device including a sensor device identity, and determines that the ID tag and the sensor device are attached to a same animal based on time information associated with the ID information and the sensor device information.
