  • Patent number: 11160247
    Abstract: A cartridge and a teatcup to be attached to the teat of an animal to be milked are disclosed. The cartridge includes an elongated sleeve, having an upper end section and a lower end section, and a teatcup liner pre-mounted in the elongated sleeve. The teatcup liner includes an upper end portion located at the upper end section, a lower end portion located at the lower end section, and a barrel portion extending between the upper and lower end portions. The barrel portion has a polygonal cross-sectional shape defining a plurality of corner portions and a plurality of side portions. The elongated sleeve includes a primary locking member.

  • Patent number: 11160251
    Abstract: An animal ear tag contains control circuitry for generating data. An antenna in the tag emits a wireless signal including the data, and an energy storage provides electric energy to the control circuitry and the antenna. The energy storage is arranged in a first part of the tag and the antenna is arranged in a second part of the tag. When attached to the animal, the first and second parts are interconnected via a shaft member inserted through an ear of the animal in such a manner that the first part is located on a first side of the ear and the second part is located on a second side of the ear. When the first and second parts are interconnected, the energy storage is located off-centered from a symmetry axis of the shaft member. As a result, the tag becomes relatively fixed in a well-defined orientation.

  • Patent number: 10849305
    Abstract: The cleaning of milk transporting conduit structure involves introducing fluid and an amount of gas into the milk transporting conduit structure, which causes a slug of fluid to be formed in and forwarded through the milk transporting conduit structure. A sensor arrangement measures at least one parameter related to the slug, and repeatedly forwards updatings of the at least one measured parameter to the data processor. Based thereon, the data processor produces an indicator of at least one quality of the cleaning process. The indicator reflects a cross-sectional profile of the slug at at least one position in the milk transporting conduit structure.

  • Patent number: 10660308
    Abstract: Within a view field, a camera records image data representing a body portion of an animal. A reader unit registers identity data from a data carrier on the animal and a data processor associates the recorded image data with the registered identity data. A passageway only allows a single animal at the time within the camera's view field. The camera is arranged so that the view field covers an identification zone within the passageway. To reduce the risk that the reader unit interferes with other nearby equipment, the data processor detects the presence of any animal within the view field of the camera based on the recorded image data, and activates the reader unit only when an animal is detected within the identification zone.
