  • Patent number: 8434424
    Abstract: A method for milking animals in a milking station (9) including a milking machine (14) for milking said animals, and a first feeding device (21) for feeding said animals intermittently or continuously with feed, is disclosed, the method comprising the steps of allowing a milking animal to enter the milking station (9); feeding the milking animal in the milking station intermittently or continuously with feed by means of the first feeding device (21); and milking the milking animal in the milking station (9) by means of the milking machine (14). According to the present invention, the feeding of the milking animal is terminated at a non-final stage of the milking in order to secure that the milking animal has terminated to consume the feed when the milking is finished.

  • Patent number: 7164133
    Abstract: A system of marked medical containers comprises at least two containers having different properties in at least one respect, and at least one machine-readable marking on each of the containers, each marking being designed to allow discrimination between the difference in properties. Each marking allows discrimination between the difference by having at least one area with different absorbence or reflectance when irradiated with radiation in non-visible frequency ranges. A specific container comprises a syringe cartridge type container for use with a preparation delivery device.

  • Patent number: 6858846
    Abstract: Provided is a method for operating a preparation delivery device wherein the device comprises a) a container for the preparation having, or being prepared for the arrangement of, an opening, b) a mechanism operable to deliver at least part of the preparation in the container through the opening, c) attachment means for connection of the container to the mechanism and d) a sensor system arranged to detect at least one predetermined property of the container or its content. The method comprises transmitting radiation towards the container position or a part thereof to allow the radiation to be affected by the container position, receiving at least a part of the affected radiation from at least an area part of the container position in a non-imaging way and comparing the characteristics of the received radiation with a predetermined characteristic representative for the predetermined property to establish whether or not the predetermined property of the container is present.
